DITF: Newly developed concept for chemical protective suits

A newly developed concept for chemical protective suits is designed to make use more comfortable and safer for the user. New materials and an improved design increase wearer comfort. The integration of sensor technology enables the monitoring of vital functions.

In the event of hazards from chemical, biological or radioactive substances, chemical protective suits (CSA) protect people from physical contact. CSAs consist of breathing apparatus, head protection, carrying frames and the suit itself. This adds up to a weight of around 25 kg. The construction of a multi-coated fabric makes the CSA stiff and provides for considerable restrictions in freedom of movement. As a result, the emergency forces are exposed to significant physical stress. For this reason, the total deployment time when using a CSA is limited to 30 minutes.

In the event of hazards from chemical, biological or radioactive substances, chemical protective suits (CSA) protect people from physical contact. CSAs consist of breathing apparatus, head protection, carrying frames and the suit itself. This adds up to a weight of around 25 kg. The construction of a multi-coated fabric makes the CSA stiff and provides for considerable restrictions in freedom of movement. As a result, the emergency forces are exposed to significant physical stress. For this reason, the total deployment time when using a CSA is limited to 30 minutes.

In a joint project with various companies, institutes and professional fire departments, work is currently underway to completely redesign both the textile material composite and the hard components and connecting elements between the two. The goal is a so-called "AgiCSA", which offers significantly more comfort for the emergency forces due to its lighter and more flexible construction. The DITF subproject focuses on the development of a more individually adaptable, body-hugging suit on the one hand, and on the integration of sensors that serve the online monitoring of important body functions of the emergency personnel on the other.

At the beginning of the project, the DITF received support from the Esslingen Fire Department. They provided a complete CSA that is used as standard today. This could be tested at the DITF for its wearing properties. The researchers in Denkendorf are investigating where there is a need for optimization to improve ergonomic wearing comfort.

The aim is to construct a chemical- and gas-tight suit that fits relatively closely to the body. It quickly became clear that it was necessary to move away from the previous concept of using woven fabrics as the basic textile material and think in terms of elastic knitted fabrics. In implementing this idea, the researchers were helped by recent developments in the field of knitted fabric technology in the form of spacer fabrics. By using spacer textiles, many of the requirements placed on the base substrate can be met very well.

Spacer textiles have a voluminous, elastic structure. From a wide range of usable fiber types and three-dimensional design features, a 3 mm thick spacer textile made of a polyester pile yarn and a flame-retardant fiber blend of aramid and viscose was selected for the new CSA. This textile is coated on both sides with fluorinated or butyl rubber. This gives the textile a barrier function that prevents the penetration of toxic liquids and gases. The coating is applied to the finished suit by a newly developed spraying process. The advantage of this process over the conventional coating process is that the desired elasticity of the suit is retained.

Another innovation is the integration of a diagonal zipper. This makes it easier to put on and take off the suit. Whereas this was previously only possible with the help of another person, the new suit can in principle be put on by the emergency responder alone. The new design is modeled on modern dry suits with diagonal, gas-tight zippers.
The new AgiSCA also features integrated sensors that allow the transmission and monitoring of the vital and environmental data of the emergency worker as well as their location via GPS data. These additional functions significantly enhance operational safety.

For the hard components, i.e. the helmet and the backpack for the compressed air supply, lightweight carbon fiber-reinforced composite materials from Wings and More GmbH & Co. KG are used.
The first demonstrators are available and are available to the project partners for testing purposes. The combination of current textile technology, lightweight construction concepts and IT integration in textiles has led to a comprehensive improvement of a high-tech product in this project.

Aerogel: Frozen Smoke for Clothing and Work Safety

Comprised of up to 99.8 percent air, aerogel is the lightest solid in the world. The material, which is also called “frozen smoke” due to its appearance and physical properties, exhibits extremely low heat conductivity which exceeds other insulations many times over. This is why NASA has already been using aerogel for aerospace projects for many years.

Despite this, it has not been possible to bind the material to textiles in a high concentration and enable straightforward further processing over the roughly 90-year history of the material. Outlast Technologies GmbH has developed an innovative process - a patent has already been filed for -  for permanently adhering large amounts of aerogel to different media, like nonwoven fabric, felt and composites materials. Their original properties are retained throughout, so they can easily be further processed using conventional production methods.

Outlast Technologies GmbH has developed an innovative process - a patent has already been filed for -  for permanently adhering large amounts of aerogel to different media, like nonwoven fabric, felt and composites materials. Their original properties are retained throughout, so they can easily be further processed using conventional production methods.

The fabrics sold under the Aersulate name are only 1 to 3 mm thick and achieve very high insulation values which are largely retained even under pressure and in moist conditions. Despite their high performance, they are still soft and can be used for shoes, clothing and work safety products, as well as for sleeping bags and technical applications.
 
“Thanks to its extraordinary physical properties, NASA has already been using aerogel for many years,” remarked Volker Schuster, Head of Research and Development at Outlast Technologies. “For example, for the insulation of its Mars rovers and for capturing dust from the tail of a comet during the Stardust mission,” he continued. Since the development of aerogel by American scientist and chemical engineer Samuel Stephens Kistler in 1931, no-one had been able to apply the versatile material to textiles in large amounts without changing their original properties, despite intensive research. This means that the products were often not only very rigid, but made processing with conventional production methods impossible due to their high degree of dust abrasion. With the newly developed Aersulate technology, which was presented for the first time in June 2022, the Heidenheim-based specialist for textile thermoregulation is opening a different chapter in insulation history.

High-performance insulation just 1 to 3 mm thick
“The consistency of aerogel can be best described as liquid dust particles which spread uncontrollably throughout a room within seconds thanks to their minimal thickness,” explained Schuster. “This is why processing is a big challenge.” Outlast Technologies has managed, after a development period of around five years, to bring an innovative process involving the adhering of aerogel between multiple layers of material to market maturity. Depending on the area of application, nonwoven fabric, felt and different composite materials can be used as the media. What is special here is that the properties of the respective textiles are not adversely affected by the Aersulate technology, meaning that they can easily be further processed with conventional means and under industrial conditions despite their acquired thermal properties.
 
As a silicate-based solid, aerogel is obtained from natural quartz sand, yet exhibits a density over 1,000 times lower than glass manufactured from the same raw material. The extraordinary thermo-insulating properties of the material are thanks to its extremely porous structure, which enables it to be composed of up to 99.8 percent air.
 
“One liter of aerogel weighs just 50 g,” explained Schuster. “Just 10 g of the material has the same surface area as a soccer field, though.” Thanks to these properties, Aersulate textiles exceed all other previously known insulation materials in terms of performance, despite the fact that they are only 1 to 3 mm thick. Tests carried out by the German Institute for Textile and Fiber Research in Denkendorf (DITF) using the Alambeta method showed that the thermal resistance of an Aersulate fleece is more than double that of a conventional fleece of the same thickness. Add to this the fact that the thermo-insulating properties of Aersulate products remain high despite pressure and wetness, while they decrease enormously with other conventional materials like felt and polyurethane foam (PU) under these conditions.

Work safety and functional clothing with Aersulate
Thanks to the textile medium, thin Aersulate products are especially suitable for the shoe and clothing industry, as well as all areas of work safety. The user benefits from different properties, depending on the intended use. “With a glove made of Aersulate just 1 mm thick, you can put your hand into boiling water without being scalded, for example,” explained Schuster. “The material’s extremely hydrophobic properties play quite literally into our hands here.” In the case of knee patches on work and functional pants, as well as shoes and soles, on the other hand, the material properties also become relevant when compression occurs. This is because the thermo-insulation properties of other materials would be reduced little by little due to moisture from the outside and sweat from the inside on the one hand, and by the continual influence of body weight on the other.
          
In addition to the human body, luggage and technical devices can also be protected from extreme temperatures and the effects of weather with Aersulate. For this purpose, corresponding cell phone or equipment pockets could be sewn into garments, for example, to maintain their battery life even at very cold outside temperatures and to safeguard the devices from overheating in case of high heat exposure. “With the broad range of possible textile medium materials, Aersulate is suitable for all applications requiring high thermal resistance on the one hand, where only a little space is available and both compression and moisture can be expected on the other,” said Schuster in summary.

New 3D printing process for sustainable fiber composite components

Nature works often with fiber composites. The construction principles of nature require little material and energy and thus ensure the survival of animals and plant species. Examples include wood, plant stalks, chitinous shells, bones or tissues such as tendons and skin. Mussel shells or spider silk are also composite tissues. We can take advantage of these principles to design and manufacture bio-based, sustainable fiber reinforced composites, which are currently in high demand. Bio-based fiber reinforced composites consist of natural fibers or cellulose fibers embedded in a bio-based matrix. The bio-based components offer properties comparable to those of commonly used glass fiber composites. The German Institutes of Textile and Fiber Research (DITF), together with Arburg GmbH + Co KG, are developing an energy- and material-efficient 3D printing process for manufacturing of such lightweight bio-based fiber composites.

The German Institutes of Textile and Fiber Research (DITF), together with Arburg GmbH + Co KG, are developing an energy- and material-efficient 3D printing process for manufacturing of such lightweight bio-based fiber composites.

In fiber composites, which occur naturally, reinforcing fibers such as collagen or cellulose fibrils are embedded in a matrix of lignin, hemicellulose or collagen. The fiber strands align with the stress patterns. Tissues are formed mostly via solution-based physio-chemical processes that take place at ambient temperature. Similar to nature, new 3D printing processes with continuous fiber reinforcement also allow the deposition of fiber strands in the right place (topology optimization) and in the appropriate direction in accordance to the load. However, natural fibers such as cellulose fibers are sensitive to higher temperatures. Therefore, they cannot be processed in the commonly employed thermoplastic 3D printing process.

The result of the research work is 3D-printed fiber composite components consisting of cellulose continuous fibers embedded in a cellulose-based matrix. Newly developed 3D-printing process enables to manufacture the composites at ambient temperature. This means that - as in nature - the material and component can be produced simultaneously in a single operation at ambient temperature.

The cellulose fiber strand is first stabilized with a binder for processing in the printer. The specially designed print head transforms the binder into a matrix with which the cellulose continuous fibers are encased. Since the cellulose fibers and the matrix have similar chemical structures, the composite component is particularly stable. The mechanical properties, such as breaking strength, are exceptionally good. The solution-based and energy-efficient manufacturing method developed by the research team can also be used in other composite materials manufacturing processes. It is particularly suitable for processing temperature-sensitive materials that are in high demand, such as natural or cellulose fibers.

The " CellLoes-3D-Druck" research project is funded by the German Federal Ministry of Education and Research as part of the "Biologisierung der Technik" ideas competition.

Funding Project Raw Material Classification of Recycled Fibers

For centuries, old textiles have been used to make tear fibers and processed into new textile products. This effective recycling is one of the oldest material cycles in the world. Today, it is not only clothing that is recycled, but also high-quality technical textiles. As the products of the textile industry evolve, so do the demands on textile recycling. The basis for this is a clear assessment and classification of raw materials.

For centuries, old textiles have been used to make tear fibers and processed into new textile products. This effective recycling is one of the oldest material cycles in the world. Today, it is not only clothing that is recycled, but also high-quality technical textiles. As the products of the textile industry evolve, so do the demands on textile recycling. The basis for this is a clear assessment and classification of raw materials.

In the research project of the German Institutes of Textile and Fiber Research Denkendorf (DITF) and the Sächsisches Textilforschungsinstitut e.V. (STFI - Saxony Textile Research Institute), a methodology is being developed that will make it possible to analyze the tearing as well as the subsequent processes with regard to fiber quality. The systematic analysis should make it possible to optimize the subsequent spinning processes in such a way that the recycled content of the yarn can be increased without the yarn properties differing significantly from those of a yarn consisting of 100% good fibers. These yarns can then be processed into sustainable textile products such as clothing or composite components.

The project, which is funded by the BMWi/IGF, is scheduled to run for two years and will end on December 31, 2022. The main benefits for the participating companies are to enable them to make greater use of secondary raw materials, to open up new markets through technologies or products developed in the project, to initiate synergies and long-term cooperation, and to prepare a joint market presence.    

The project includes several steps:

  • Material selection and procurement
    Cotton fibers to be processed are obtained from used textiles (T-shirts) and waste from the cotton spinning mill. Aramid fibers are processed from used protective clothing and technical textiles.
  • Optimization of the preparation / dissolution of the textiles
    To ensure that the fibers are detached from the corresponding textiles as gently as possible and with a not too high reduction, exact settings have to be found for the tearing process, which are technologically very demanding and require a lot of experience.
  • Determination of the quality criteria for the evaluation of the fiber dissolution
    In order to define the quality criteria, the fibers coming from the tearing mill are determined by means of an MDTA-4 measuring device from Textechno GmbH & Co. KG. The criteria determined are to be used to characterize the (lowest possible) fiber shortening caused by the tearing process.
  • Determination of optimized settings in the spinning process
    In order to determine the optimum settings for producing a yarn from the recycled fibers, they are spun after the rotor spinning process. By adjusting the spinning process, the aim is to produce a yarn that has good uniformity and also appropriate firmness.
  • Production and comparison of yarns from recycled raw materials
    In order that the recycled fibers - consisting of aramid and cotton - can each be used to produce an area-measured material, the material is to be processed at industrial scale. For this purpose, the fibers are processed over a complete blowroom line with following sliver production over adapted cards. After drawing and the following roving production, yarns are produced according to the rotor or ring spinning process. The finished yarns are used to produce knitted fabrics.
  • Coordination, analysis of results and preparation of reports
    The final report is prepared by the DITF and the STFI. The results will be transferred through publications, technical information to associations and trade fair presentations. Regular meetings with the participating companies are planned.

Textination spoke with Stephan Baz, Deputy Head of the Competence Center Staple Fiber, Weaving & Simulation, Head of Staple Fiber Technology and Markus Baumann, Research Associate at the Competence Center Staple Fiber, Weaving & Simulation (both DITF) as well as Bernd Gulich, Head of Department Nonwovens/Recycling and Johannes Leis, Research Associate Focus Nonwovens/Recycling (both STFI) about the current status of the funding project.

What is the current status of the project?
We are currently in the phase of carrying out trials and the iterative optimization of several project components. As expected, several loops are necessary for the mechanical preparation itself and also for the adjustment of the spinning process with the different variants. Ultimately, after all, the project aims at coordinating the processes of mechanical preparation and spinning as processing in order to achieve optimum results. At the same time, determining the quality criteria of the fibers produced is not trivial. This also requires the further development of processes and test methods that can be implemented productively in industry and that allow the quality of the fibers produced to be assessed effectively and unaffected by residual yarns, for example. What is really remarkable is the interest and willingness of the industry to drive the project work forward. The considerable quantities of materials required for our trials were purchased from ReSales Textilhandel und -recycling GmbH, Altex Textil-Recycling GmbH & Co. KG and Gebrüder Otto GmbH & Co. KG. Furthermore, with Temafa Maschinenfabrik GmbH, Nomaco GmbH & Co. KG, Schill + Seilacher GmbH, Spinnerei Neuhof GmbH & Co. KG and Maschinenfabrik Rieter AG, many members of the project-supporting committee are actively involved in the project, from consulting to the providing of technologies. The company Textechno Herbert Stein GmbH & Co. KG has provided a testing device of the type MDTA4 for the duration of the project and supports our work with regard to the evaluation of the mechanically prepared fibers. We are of course particularly pleased about this, as it has allowed us to look at and analyze several technologies in both mechanical preparation, testing and spinning. We expect to be able to make more detailed statements at the beginning of the coming year.

Which approaches do you think are particularly promising?
With regard to technologies, we must refer to the evaluation and analysis of the trials, which are currently still ongoing. We will be able to go into more detail in the first quarter of next year.

Of course, things are already emerging. With meta-aramid waste, promising approaches could be found very quickly; with post-consumer cotton, this is considerably more complex. Obviously, there is a link between the quality of the raw material and the quality of the products. In some cases, we have already been able to determine very low average fiber lengths in the procured goods; to a certain extent, these are of course directly reflected in the output of our processes. From this, and this is not a new finding, a great importance of the design of the textiles is again derived.

What are the challenges?
In addition to the expected high short fiber content, the residual yarns after the tearing process are an issue of particular focus. The proportion of these residual yarns can vary between the materials and preparation technologies, but the further dissolution of the products of the tearing process is essential.

If the processes are considered further in a utilization phase, the question of design naturally also arises for the best possible use of recycled fibers. Many problems, but also the approaches to solutions for the use of comparatively short fibers, can also be expected to apply to the (multiple) use of mechanically recycled fibers.

Can we speak of upcycling in the final product?
We see yarn-to-yarn recycling neither as upcycling nor downcycling, but as closed-loop recycling. The background is that the products are to go into the same application from which they came and have to compete with primary material. This means that certain specific requirements have to be met and at the same time there is considerable price pressure. In the case of downcycling, a significant reduction in properties is accepted, while in the case of upcycling, the higher-priced application can make up for the reprocessing effort. In the attempt to produce yarn material again from yarn material, both are only permissible to a small extent. This represents the particular challenge.

What does a recyclate prepared from used textiles mean for the spinning process?
Part of this question is to be answered in the project by the detailed classification of the processed fibers and is thus the subject of the tests currently underway. It turns out that, in addition to the rather obvious points such as significantly reduced fiber length, process disturbances due to undissolved fabrics and yarn pieces, there are also less obvious aspects to be considered, such as a significantly increased outgoing quantity for processing in the spinning process. The outgoing quantity is of particular interest here, because in the end the newly produced yarn should also contain a considerable proportion of prepared fibers.

What consequences does this have for textile machinery manufacturing?
The consequences that can already be estimated at the present time are that, particularly in the processing of cotton, the machinery in the spinning preparatory mill is specialized in the processing of (new) natural fibers with a certain amount of dirt. In contrast to new fibers, processed fibers are clean fibers with a significantly higher proportion of short fibers. Elements that are good at removing dirt also reject an increased amount of short fibers, which can lead to unintentionally high waste quantities under certain circumstances. It is therefore necessary to adapt the established machine technology to the new requirement profile of the raw material "processed fibers". Analogous adaptations are probably necessary along the entire processing chain up to the yarn. In the drafting system of the spinning machine, of course, this is due more to the high short fiber ratio than to elements that have been optimized for cleaning out dirt and foreign substances.

Cellulose Fibre Innovation of the Year 2022: Cellulose Fibre Solutions are expanding from hygiene and textiles as well as non-wovens up to alternatives for carbon fibres for light-weight applications.

Great submissions made the nomination for the Innovation Award difficult. All of them present promising sustainable solutions in the field of cellulose fibres value chain. Six of them now get the chance to demonstrate their potential to a wide audience in Cologne (Germany), and online.

For the second time, nova-Institute grants the “Cellulose Fibre Innovation of the Year” within the framework of the “International Conference on Cellulose Fibres 2022” (2-3 February 2022). The advisory board of the conference nominated six  products, ranging from cellulose made of orange- and wood pulp to a novel technology for cellulose fibre production. The presentations, election of the winner by the conference audience and the award ceremony will take place on the first day of the conference.

Cellulose fibres show an increasingly expanding wide range of applications, while at the same time markets are driven by technological developments and political framework conditions, especially bans and restrictions on plastics and increasing sustainability requirements. The conference provides rich information on opportunities for cellulose fibres through policy assessment, a session on sustainability, recycling and alternative feedstocks as well as latest development in pulp, cellulose fibres and yarns. This includes application such as non-wovens, packaging and composites.

Here are the nominees:
Carbon Fibres from Wood – German Institutes of Textile and Fiber Research Denkendorf (Germany)
The HighPerCellCarbon® technology is a sustainable and alternative process for the production of carbon fibres made from wood. The technology starts with wet spinning of cellulosic fibres using ionic liquids (IL) as direct solvent in an environmentally friendly, closed loop filament spinning process (HighPerCell® technology). These filaments are directly converted into carbon fibres by a low-pressure stabilisation process, followed by a suitable carbonisation process. No exhaust fumes or toxic by-products are formed during the whole process. Furthermore, the approach allows a complete recycling of solvent and precursor fibres, creating a unique and environmentally friendly process. Carbon fibres are used in many lightweight applications and the fibres are a sustainable alternative to fossil-based ones.

Fibers365, Truly Carbon-Negative Virgin Fibres from Straw – Fibers365 (Germany)
Fibers365 are the first carbon-negative virgin straw fibres on the market. The Fibers365 concept is based on a unique, state of the art process to provide functional, carbon negative, and competitive non-wood biomass products such as virgin fibres for paper, packaging and textile purposes as well as high value process energy, biopolymer and fertilizer side streams. The products are extracted from the stems of annual food plants such as straw by a chemical-free, regional, farm level steam explosion pulping technology, allowing an easy separation of the fibres from sugars, lignin, organic acid and minerals. In the case of annual plants, CO2 emissions are recaptured within 12 months from their production date, offering “instant”, yearly compensation of corresponding emissions.

Iroony® Hemp and Flax Cellulose – RBX Créations (France)
Iroony® is a branded cellulose made by RBX Créations from hemp. This resistant hemp plant grows quickly within in a few months, massively captures carbon and displays a high content of cellulose. The biomass is directly collected from French farmers who cultivate without chemicals or irrigation, in extended rotation cycles, contributing to soil regeneration and biodiversity. For a diversified supply, the hemp can be combined with organically-grown flax. Through its patented process, RBX Créations extracts high-purity cellulose, perfectly suitable for spinning technologies such as HighPerCell® of DITF research centre. The resulting fibres display versatile properties of fineness, tenacity and stretch, for applications like clothing or technical textiles. Iroony® combines low impact, trackability and performance.

SPINNOVA, Sustainable Textile Fibre without Harmful Chemicals – Spinnova (Finland)
Spinnova’s innovative technology enables production of sustainable textile fibres in a mechanical process, without dissolving or any harmful chemicals. The process involves use of paper-grade pulp and mechanical refining to turn pulp into microfibrillated cellulose (MFC). The fibre suspension consisting of MFC is extruded to form textile fibre, without regeneration processes. The Spinnova process does not generate any side waste, and the environmental footprint of SPINNOVA® including 65 % less CO2 emissions and 99 % less water compared to cotton production. Spinnova’s solution is also scalable: Spinnova targets to reach 1 million tonnes annual production capacity in the next 10 to 12 years.    

Sustainable Menstruation Panties: Application-driven Fibre Functionalisation – Kelheim Fibres (Germany)
Kelheim’s plant-based and biodegradable fibres contribute significantly to a sustainable future in the field of reusable hygiene textiles. Through innovative functionalisation they are specifically adjusted to the requirements of the single layers and thereby reach a performance comparable to that of synthetic fibres. A unique duality in fibre technology is created: sustainably manufactured cellulosic fibres that allow for high wearing comfort and reusability with extraordinary, durable performance. Fibre concepts comprise Celliant® Viscose, an in-fibre infrared solution and Danufil® Fibres in the top sheet, Galaxy, a trilobal fibre for the ADL, Bramante, a hollow viscose fibre, in the absorbing core and a water repellent woven fabric, a biodegradable PLA film or a sustainable coating as a back sheet.

TENCEL™ branded Lyocell Fibre made of Orange and Wood Pulp – Orange Fiber (Italy)
Orange Fiber is the world's first company to produce a sustainable textile fibre from a patented process for the extraction of cellulose to be spun from citrus juice leftovers, which are more than 1 million tonnes a year just in Italy. The result of our partnership with Lenzing Group, leading global producer of wood-based specialty fibres, is the first ever TENCEL™ branded lyocell fibre made of orange and wood pulp. A novel cellulosic fibre to further inspire sustainability across the value chain and push the boundaries of innovation. This fibre, part of the TENCEL™ Limited Edition initiative, is characterized by soft appeal and high moisture absorbance and has already obtained the OEKO-TEX Standard 100 certificate and is undergoing a diverse set of other sustainability assessments.

Biomolecules from renewable Raw Materials for the Textile Industry

Water-repellent and more: coating textiles sustainably with chitosan

Textiles can be coated with the biopolymer chitosan and thus made water-repellent by binding hydrophobic molecules. The good thing is that this can also replace toxic and petroleum-based substances that are currently used for textile finishing. In the last few years Fraunhofer IGB and partners in the HydroFichi project have researched how this can be done: A technology has been developed to provide fibers with the desired properties using biotechnological processes and chitosan.

Water-repellent and more: coating textiles sustainably with chitosan

Textiles can be coated with the biopolymer chitosan and thus made water-repellent by binding hydrophobic molecules. The good thing is that this can also replace toxic and petroleum-based substances that are currently used for textile finishing. In the last few years Fraunhofer IGB and partners in the HydroFichi project have researched how this can be done: A technology has been developed to provide fibers with the desired properties using biotechnological processes and chitosan.

The manufacture of textiles is, even nowadays, still largely characterized by the use of chemicals: biotechnological processes, enzymes and renewable raw materials have so far played a subordinate role. For example, at present chiefly perfluorinated chemicals are used when finishing textiles to obtain water- and oil-repellent properties. These are harmful to health and also only degradable to a small degree, which is why they remain in the environment for so long.

The Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB has been researching sustainable biobased alternatives for some time. In the HydroFichi project – short for Hydrophobic Finishing with Chitosan – which was completed at the end of January 2021, researchers at the institute developed a way of producing chitosan from waste streams and using the biopolymer not only as a sizing agent in the processing of yarns, but also for the functionalization of textiles in the finishing process.

Chitosan from waste for environmental protection, medical purposes or textiles
Chitosan is a renewable raw material that is derived from chitin; after cellulose, it is the second most common naturally occurring biopolymer. Sources of the nitrogen-containing polysaccharide can be crab shells from fishing waste, insect skins and shells that result from the production of animal feed, or – as a vegan variant – the cell walls of mushrooms. The structure of the two molecules is very similar; the only difference is an acetyl group, which is removed when it is converted to chitosan. Chitin is insoluble in water and most organic solvents. Chitosan is also not readily soluble; however, the addition of mild acids makes the biopolymer water-soluble and it can therefore be used as a textile auxiliary.

In order to isolate chitosan from a particular waste stream, chitin must first be obtained from the starting materials by means of demineralization and deproteinization and then its derivative chitosan. The properties of chitosan can be individually adapted by choosing the appropriate conditions. The biomolecule produced in this way can be used directly in a wide variety of practical applications – for example as a flocculant in wastewater treatment or as a drug carrier in medicines.

There are also numerous conceivable uses for chitosan in the textile industry. In sizing, for example, the efficiency of the natural substance has proved convincing in pilot scale tests carried out by the German Institutes of Textile and Fiber Research Denkendorf. Here, the effectiveness was shown in the significantly lower roughness of the yarns after weaving textile fabrics. The values achieved with chitosan from insects were comparable to those from commercial crab shells. In the future, this fact will enable completely new possibilities of extraction in line with the bioeconomy.

As a renewable raw material, chitosan replaces fossil chemicals
“Our aim in the HydroFichi project was to provide the textile industry with a raw material for a wide variety of applications that can be obtained from renewable educts, at the same time avoiding chemicals that damage the environment and health,” explains project manager Dr. Achim Weber, deputy head of the innovation field Functional Surfaces and Materials at Fraunhofer IGB. “In addition to simple coating with chitosan, which protects the fibers, we were also able to use the substance as an anchor molecule to create cross-linking points for a wide variety of functional groups and thus to provide textiles with specific properties such as making them water-repellent. Chitosan can therefore function as a matrix material or template at the same time, and this can be done with a wide variety of fiber materials.”

The finishes were evaluated using standardized tests, but also with specially designed test stands and methods. For example, measurements on treated textiles showed contact angles of over 140°. This means that the fabrics are very water-repellent and confirms that the processing of the textiles has been successful. In a next step, the technology developed at the IGB is to be transferred from the laboratory scale to the much larger pilot scale in order to make the sustainable biomolecule ready for market use as quickly as possible, for example in the sports and outdoor sector.

For the first time biotechnological processes in textile finishing
In the project, the IGB scientists and four partners from the textile industry – the German Institutes of Textile and Fiber Research Denkendorf (DITF), J.G. Knopf's Sohn GmbH, Helmbrechts, and Textilchemie Dr. Petry, Reutlingen – were able for the first time to establish biotechnological processes in raw material extraction and finishing that have proven to be compatible with all textile processes. So far, this is a unique selling point in the finishing of textiles. “We have all recognized the great potential of chitosan for efficient hydrophobization and as a functional carrier. And, thanks to the good cooperation, we were able to successfully establish techniques for tailor-made functionalization of textiles,” adds Dr. Thomas Hahn, who conducts research in the innovation field of Industrial Biotechnology at the IGB. “In addition, other fields of application for the biopolymer are very promising. That is why we initiated the follow-up project ExpandChi immediately after HydroFichi, in which together with our partners techniques are to be developed to use biobased chitosan as a functional carrier to replace other synthetic polymers, for example for a special anti-wrinkle or flame-retardant coating. The textile industry is very interested in utilizing such a sustainable biomolecule as quickly as possible.“

The “HydroFichi” project was funded by the German Federal Ministry of Education and Research (BMBF) under promotional reference 031B0341A; the follow-up project “ExpandChi”, which began in February 2021, is funded under promotional reference 031B1047A.

Protection against Corona: Materials research provides findings at institutes of the Zuse Community

As the year draws to a close, expectations are growing that protection against COVID-19 will soon be available. Until this is the case for large sections of the population, the successes achieved in research and industry to protect against the virus in 2020 offer a good starting point in the fight against corona and beyond. At institutes in the Zuse community, progress have been made not only in medical but also in materials research.

As the year draws to a close, expectations are growing that protection against COVID-19 will soon be available. Until this is the case for large sections of the population, the successes achieved in research and industry to protect against the virus in 2020 offer a good starting point in the fight against corona and beyond. At institutes in the Zuse community, progress have been made not only in medical but also in materials research.

These successes in materials research include innovations in the coating of surfaces. "In the wake of the pandemic, the demand for antiviral and antimicrobial surfaces has risen sharply, and we have successfully intensified our research in this area," explains Dr. Sebastian Spange, Head of Surface Technology at the Jena research institute INNOVENT. He expects to see an increasing number of products with antiviral surfaces in the future. "Our tests with model organisms show that an appropriate coating of surfaces works", emphasizes Spange. The spectrum of techniques used by INNOVENT includes flame treatment, plasma coating and the so-called Sol-Gel process, in which organic and inorganic substances can be combined in one layer at relatively low temperatures. According to Spange, materials for the coatings can be antibacterial metal compounds as well as natural substances with antiviral potential.

Nonwovens produced for mask manufacturers
In 2020, the textile expertise of numerous institutes in the Zuse community ensured that application-oriented research could prove its worth in the practical fight against pandemics. After the shortage of mask supplies in Germany at the beginning of the pandemic, textile research institutes reacted to the shortage by jumping into the breach. The Saxon Textile Research Institute (STFI), for example, converted its research facilities to the production of nonwovens to supply German and European manufacturers of particle filtering protective masks. "From March to November 2020, we supplied nonwovens to various manufacturers in order to provide the best possible support for mask production and thus help contain the pandemic. At a critical time for industry and the population, we were able to help relieve critical production capacity - an unaccustomed role for a research institute, but one we would assume again in similar situations," explains Andreas Berthel, Managing Commercial Director of STFI.

Development of reusable medical face masks
For the improvement of everyday as well as medical face masks the German Institutes for Textile and Fiber Research (DITF) are working on this project. In cooperation with an industrial partner, they are currently developing in Denkendorf, among other things, reusable medical face masks made of high-performance precision fabric using Jacquard weaving technology. The multiple use avoids waste and possible supply bottlenecks.

There are regulations for all types of masks, now also for everyday masks. At Hohenstein, compliance with standards for masks is checked. A new European guideline defines minimum requirements for the design, performance evaluation, labelling and packaging of everyday masks. "As a testing laboratory for medical products, we test the functionality of medical masks from microbiological-hygienic and physical aspects", explains Hohenstein's Managing Director Prof. Dr. Stefan Mecheels. In this way, Hohenstein supports manufacturers, among other things, with technical documentation to prove the effectiveness and safety. Respiratory protection masks (FFP 1, FFP 2 and FFP 3) have been tested at the Plastics Centre (SKZ) in Würzburg since the middle of this year. Among other things, inhalation and exhalation resistance and the passage of particles are tested. In addition, SKZ itself has entered into mask research. In cooperation with a medical technology specialist, SKZ is developing an innovative mask consisting of a cleanable and sterilizable mask carrier and replaceable filter elements.

ILK tests for mouth-nose protection
The fight against Corona is won by the contributions of humans: Of researchers in laboratories, of developers and manufacturers in the Industry as well as from the citizens on the street.
Against this background, the Institute for Air and Refrigeration Technology (ILK) in Dresden has carried out investigations into the permeability of the mouth and nose protection (MNS), namely on possible impairments when breathing through the mask as well as the protective function of everyday masks. Result: Although the materials used for the mouth-nose protection are able to retain about 95 percent of the exhaled droplets, "under practical aspects and consideration of leakages" it can be assumed that about 50 percent to 70 percent of the droplets enter the room, according to the ILK. If the mask is worn below the nose only, it can even be assumed that about 90 percent of the exhaled particles will enter the room due to the large proportion of nasal breathing. This illustrates the importance of tight-fitting and correctly worn mouth and nose protection. "On the other hand, from a physical point of view there are no reasons against wearing a mask", ILK managing director Prof. Dr. Uwe Franzke emphasizes. The researchers examined the CO2 content in the air we breathe as well as the higher effort required for breathing and based this on the criterion of overcoming the pressure loss. "The investigations on pressure loss showed a small, but practically irrelevant increase," explains Franzke.

The complete ILK report "Investigations on the effect of mouth and nose protection (MNS)" is available here.

  • High internationality and excellent visitor quality ensure top ra-tings

The trade fair combination for visual communication and haptic adver-tising, EXPO 4.0, was an impressive event with 421 exhibitors and 12,518 visitors held from 30 January to 1 February 2020 in Stuttgart:
TV TecStyle Visions, trade fair for textile decoration and promotion, enriched the trade fair combination with a top-class exhibitor offering, high internationality and an accompanying programme characterised by innovations and know-how transfer. It proved its status as a leading trade fair for the European textile decoration industry in an impressive way: 262 exhibitors, including all relevant companies from the exhibition segments textiles and technology, mark the importance as a European industry get-together every two years in Stuttgart. The leading trade fair confronts the uncertain European market situation and uncertainties in trade, the number of exhibitors remained almost constant compared to the previous event (2018: 270). The 126 international exhibitors came from 21 countries to Stuttgart. The top 5 countries of origin are Germany, Great Britain, Spain, Poland and Italy.
 
Many decision-makers from the Germany/Austria/Switzerland region
Within the framework of TV TecStyle Visions the visitors were particularly interested in the different printing processes, embroidery and textiles. The EXPO 4.0 trade fair combination attracted 17 per cent international visitors from 50 countries to Stuttgart. The appeal of the leading European trade fair is manifested with the top visitor countries Switzerland and Austria. 35 percent of all visitors to TV TecStyle Visions travelled more than 300 kilometres to Stuttgart.

The quality of the visitors has been a reliable constant for years: four out of five visitors are actively involved in purchasing and procurement decisions, 87 percent have concrete intentions to invest and 84 percent of the visitors want to invest in the next 12 months. An overall rating of the trade fair combination of 2.0 ("good") and a return visit rate for 4 out of 5 visitors highlight the positive synergy effects created by the parallel timing of the three trade fairs in the trade fair combination EXPO 4.0. This is also reflected in the amount of time visitors spend at the event - on average 4.8 hours at the three trade fairs.
 
Comprehensive accompanying programme
Apart from the exhibition offering, TV TecStyle Visions has been convincing for years with a comprehensive accompanying programme. Not only real innovations and trends that move the industry are showcased at the stands. At this year's trade fair the TecCheck Area acts as a look into the near future. In the digital microfactory nine companies demonstrated the possibilities of digitalisation in production under the coordination of DITF (German Institutes for Textile and Fibre Research, Denkendorf). A polo-shirt was made in one hour, from the 3D design and conception, through to the printing, thermosetting, cutting and making-up of the garment. The trend topics of the industry and the degree of innovation were also shown in the forum, such as the option of personalisation and automation in textile finishing/textile decoration/garment decoration. The TecStyle Fashion Show, the forum and also Charlie's Corner gave visitors a platform to exchange information and ideas and for know-how transfer, as well as another presentation possibility for the exhibitors.
 
The next TV TecStyle Visions takes place in the EXPO 4.0 trade fair combination with WETEC and GiveADays in two years. The dates 10 to 12 February 2022 are currently reserved.

Clothing Production in the Future

Individualisation, automation and digitalisation: micro-factories are the way forward for the future of clothing production and will be the main theme of Texprocess in Frankfurt am Main from 14 to 17 May 2019.

“Send your favourite design to the manufacturer today via an app and wear your individually designed, perfectly fitting trainers or shirt tomorrow.
It’s a long time since this was just a pipe dream for the future,” says Michael Jänecke, Director Brand Management Technical Textiles and Textile Processing at Messe Frankfurt. “Behind it, however, lies a host of complex processes, involving production, processing and logistics. Micro-factories, based on networked and integrated procedures, represent the progressive way of making textile processing quicker, more flexible and, because it is more local, also more sustainable; whilst, at the same time, producing personalised products.”

Micro-factories, based on networked and integrated procedures, represent the progressive way of making textile processing quicker, more flexible and, because it is more local, also more sustainable; whilst, at the same time, producing personalised products.”

In a total of four micro-factories at the up-coming Texprocess, trade visitors will be able to get an idea of how integrated textile processing works and where micro-factories are already being used.


Digital Textile Micro-Factory: on-demand and virtual reality
Following the success of the last event, Texprocess, in collaboration with the German Institutes of Textile and Fibre Research in Denkendorf (Institute für Textil- und Faserforschung Denkendorf – DITF) and partners from industry, will once again be presenting a ‘Digital Textile Micro-Factory’ display - and thus fully networked production chains - live in Hall 4.1. New this year: the ‘Digital Textile Micro-Factory’ will showcase three production lines – one for apparel manufacture, one for 3D-knitted shoes and one for processing technical textiles, largely for the motor-vehicle and furniture industries.

‘Fashion Line’ integrates virtual prototypes and customer interaction
The fashion industry plays a central role in the ‘Digital Textile MicroFactory’. The customer’s digital doppelganger is becoming more and more important in development departments in the apparel industry as the starting point for individualised and perfectly fitting clothes and for links with finishing departments. In the context of the micro-factory’s production line, it is the key feature.

The production line demonstrates the various stages involved, including CAD/Design, printing, cutting out, assembly, finishing and labelling. New approaches also combine 3D simulations of clothing with direct data transfer in virtual reality (VR) and augmented reality (AR). Instead of presenting the customer with physical examples of the clothing to be produced, the examples are visualised as virtual objects. And during the production process, the customer has the opportunity for direct input into the design of the product in question. This direct interaction between the 3D simulation of an item, the representation in VR/AR displayed on the customer’s own hardware and the direct impact on the production process has never been shown before in this way. Partners of the ‘Fashion Line’ are: Assyst (CAD/design), Mitwill (materials), Caddon, ErgoSoft, Mimaki and Multiplot (printing), Zünd (cutting), Juki and Stoll (assembling), Veit (finishing) and Vuframe (AR/VR).

3D knitting on the way to Industry 4.0
From 3D image to finished prototype in 18 minutes: the future is here in the world of knitting too! The ‘Digital Textile Micro-Factory’ at Texprocess and Techtextil shows a workflow which enables 3D-knitted uppers for shoes to be produced directly from the customer’s own particular foot measurements.
The ‘3D-knitting Line’ of the micro-factory demonstrates the process from the 3D model to the creation of a geometrically accurate knitting pattern by the software, based on the 3D data set, and the development of a specification of the final knitting data, through to the manufacture of a 3D-knitted prototype. Knitting is the additive manufacturing process for textiles. The ‘3D-knitting Line’ is partnered by Stoll.

Processing technical textiles in the micro-factory
Industry 4.0 live: the focus of the third production line of the ‘Digital Textile Micro-Factory’ 2019 is on the automated processing of technical textiles, personalised for the individual customer, taking us right through to the finished product. Trade visitors will see here on-demand inkjet printing and networked machines with integrated sensors, which are linked through a bus system – a future-oriented topic for integrated manufacturing. A robot arm with a special claw for use with textiles sorts the cut items as they emerge from the cutter in a free-moving open shuttle. The items to be sewn are conveyed automatically to the sewing stations. Tracing and tracking procedures show the progress of each order through the individual stages of the manufacturing process using an auto ID. In addition, the display will also show how creative ideas from the Cloud can be incorporated in the manufacture of technical products. Technology meets creativity. Partners of the production line: Mitwill (design), ErgoSoft (RIP), Caddon (colour management), HP (large-format inkjet printing), Zünd (cutting), Dürkopp Adler (networking, integration of an open shuttle, sewing), Veit (finishing), Next Robotics (material handling).

Smart Textiles Micro-Factory: industrial-type production of smart textiles
In their ‘Smart Textiles Micro-Factory’, located in the walkway between Halls 4.1 and 5.1, the Institute for Textile Technology (ITA) at the RWTH Aachen University, together with partners from industry and research, will be producing a ‘smart’ pillow which, with the help of integrated LEDs, provides new ways of interaction. With this demonstration, the partners in the project will present an exemplary, industrial-style manufacturing process for a smart textile from design to finished product. The prototype of the pillow was displayed in advance at Heimtextil 2019. The following are all involved in the ‘Smart Textiles Micro-Factory’: the Institute for Textile Technology (ITA) of the RWTH Aachen University (project coordination), Gerber Technology GmbH (cutting), the Korea Institute for Industrial Technology KITECH (electronics), VETRON TYPICAL Europe GmbH (sewing), Wear it GmbH (product design and concept) and ZSK Stickmaschinen GmbH (embroidery).
 
World of Digital Fashion: customisation of apparel
Six companies have grouped together under the ‘World of Digital Fashion’ umbrella. They work in areas of visualisation, CAD-cutting systems, automated body measurement, cutting out and process automation. Together, they will be showcasing, in Hall 4.0, ways of integrating and combining their products in a variety of workflows within the value creation chain and will enable visitors to experience what the digital process chain is like in practice. The focus will fall particularly on the customisation of apparel and fashion items. Partners of the ‘World of Digital Fashion’ are: Browzwear Solutions and Tronog (visualisation), Software Dr. K. Friedrich (CAD), Fision (automated body measurement), Bullmer (cutting), as well as Gertsch Consulting and Mode Vision (process automation).

Micro-factory presented by Efka and Gemini: easy to implement
Manufacturers of drive mechanisms for industrial sewing machines Efka will,in collaboration with CAD suppliers Gemini, be showcasing the production of a knitted garment that can be individually designed. The core element of their micro-factory, which closely reflects industrial practice, is the link to the sewing stage of production, something which is already available today as an economic, partially automated solution. The display presents a solution that can be easily implemented and adopted by most companies, using already available resources.

The textile sector made its first appearance in the USA in 2000. This was followed by highly successful presentations in Shanghai in 2002, in Mumbai in 2007 and in Moscow in 2012.

“Taking ‘High-Tex from Germany’ to Atlanta again was a very good decision. The southeast of the USA has a long tradition of textile manufacturing. It is home to many companies that are always on the lookout for innovative textiles and machines for textile production and processing”, explained Detlev Rünger, German Consul General in Atlanta during the ‘High-Tex from Germany’ press conference. “Fairs bring people together. And this was evident here in Atlanta. With the overseas exhibition programme, we give small to medium-sized companies the chance to show their products in foreign markets”, said Patrick Specht of the Trade Fair Policy and EXPO Participations division of the BMWi.

“‘High-Tex from Germany’ within the framework of Techtextil North America and Texprocess Americas was a very good platform for our small to medium-sized companies. After Techtextil and Texprocess in Frankfurt, these two events are the second-most important editions of the trade-fair duo. ‘High-Tex from Germany’ came fully up to our expectations and anyone who failed to take part missed a great opportunity to be noticed”, said Marc Lorch, Member of the Board of Zwissler Holding, who represented the participating companies as exhibitor president.

Michael Metzler, Sales President of ZSK Stickmaschinen, confirmed this saying, “A German pavilion of this scope makes us extremely visible. Thanks to the excellent organisation, we were also able to concentrate on promoting our company and products.” In addition to the appealing exhibition-stand concept and the excellent organisation, the companies taking part were particularly pleased with the high visitor standard. “We regularly exhibit at Techtextil North America but taking part in ‘High-Tex for Germany’ resulted in our best ever day at a fair here. The pavilion is a real eye-catcher”, said Thomas Wiederer, Area Sales Manager, Brückner Textile Technologies. “The visitors to our exhibition stand were very interested in our products. We gained potential customers and were able to make numerous high-grade contacts. The level of interest shown in our highly innovative e-textile solutions, which are completely new in the sector, was very high. We are looking forward to the follow-up phase”, said Andreas Lanyi, Vice President Digital Unit and Internet of Things of the Hamburg-based start-up, Lunative Laboratories.

Besides gaining new customers, the focus of the companies taking part in ‘High-Tex from Germany’ was on cultivating customer relations. “The German pavilion in Atlanta once again gave us a good opportunity to get to know the US market better. We have had a factory in the vicinity of Atlanta for two years now and aim to expand our network in the long term”, said Ronny Schröder, Associate Sales Director Technical and Comfort Products, Sandler. “We like making presentations within the framework of the German pavilion very much”, added Georg Voggenreiter, Technical Sales, Maschinenfabrik Herbert Meyer. “Once again, ‘High-Tex from Germany’ was a good starting point for cultivating contacts with our customers in the USA.”

The companies taking part in ‘High-Tex from Germany’ made their presentations on around 1,300 square metres of exhibition space with their own exhibition stands, with selected exhibits on a central ‘Plaza’, in guided tours and no less than 35 lectures. Additionally, the German Institutes of Textile and Fibre Research (Deutsche Institute für Textil- und Faserforschung – DITF), the Association of the Finishing, Yarns, Woven Fabrics and Technical Textiles Industry (Industrieverband Veredlung, Garne, Gewebe und Technische Textilien – IVGT), the Tübingen-Reutlingen-Zollernalb location agency and the German American Chamber of Commerce of the Southern U.S. provided insights into current research projects and offered information about the sector.

As well, numerous exhibitors, including Brother, Epson, Ergosoft and Mimaki, will be showing digital printing technologies.

„“We are expanding our programme on the subject of digital printing in response to the growing demand for digitalised technologies for processing garments, technical textiles and flexible materials. This programme is of particular interest to manufacturers of technical textiles and companies that process textiles”, says Michael Jänecke, Head of Brand Management, Textiles and Textile Technologies, Messe Frankfurt.

Elgar Straub, Managing Director, VDMA Textile Care, Fabric and Leather Technologies: “Thanks to digital textile printing, it is now possible to print apparel, shoes and technical textiles directly. Given the general trend towards individualisation, demand for individualised products is increasing in the apparel industry. This is turning digital textile printing into one of the future-oriented technologies for companies that process garments and textiles.”

European Digital Textile Conference at Texprocess

In cooperation with Texprocess and Techtextil, the World Textile Information Network (WTiN) will hold the European Digital Textile Conference at Texprocess for the first time. The focus of the conference will be on digital textile printing for adding functional and decorative features to technical textiles. The WTiN European Digital Textile Conference will take place in ‘Saal Europa’ of Hall 4.0 from 09.00 to 16.30 hrs on
10 May. Tickets for the conference can be obtained from WTiN under
https://www.digitaltextileconference.com/edtc2017/

The subjects to be covered in the lectures include direct yarn colouring in the embroidery plants (Coloreel, Sweden), plasma pre-treatment for textiles before digital printing (GRINP, Italy) and chemical finishing for textiles using inkjet printing technology (EFI-REGGIANI, USA).

Texprocess Forum to spotlight digital printing technology

Digital printing technology will also be the subject of a separate lecture block at Texprocess Forum. At this international conference, experts from science and industry will focus on the latest findings relating to subjects of major importance to the sector in over 30 lectures and panel discussions on all four days of the fair. Texprocess Forum is free of charge for visitors of Texprocess and Techtextil and will be held in Hall 6.0. For the first time, three partner organisations are organising the lecture blocks: DTB – Dialogue Textile Apparel, the International Apparel Federation (IAF) and the World Textile Information Network (WTiN).

Digital Textile Microfactory

In cooperation with the German Institutes of Textile and Fibre Research Denkendorf (DITF) and renowned textile companies, Texprocess presents the complete interlinked textile production chain – the Digital Textile Microfactory – live in Hall 6.0. The digital-printing station shows large-scale inkjet printing in the form of sublimation printing on polyester and pigment printing on cotton and blended fabrics. Production orders can be combined flexibly and printed colour consistently with a variety of printing parameters. Ensuring optimum printing results at this station are hardware and software partners, Mimaki and Ergosoft, and Coldenhove and Monti Antonio. In addition to the Microfactory partners, other renowned companies, including Brother and Epson, will be showing state-of-the-art printing processes for textiles and apparel at Texprocess.

Digital-printing Outlook

Originally developed for fashion fabrics, digital textile printing is also used for printing technical textiles, such as sports clothing, and textiles for the automobile industry whereby the primary focus is on functionalising textiles. For example, swimwear can be made more colour fast to resist frequent contact with water and chlorine, and exposure to the sun. Also, textiles can be finished by applying chemicals via an inkjet printer and thus be given dirt-repellent, antimicrobial and fire-retardant properties. Additionally, using an inkjet printer in the finishing process is advantageous in terms of sustainability and efficiency.
