Lenzing: Sustainable geotextiles as glacier protection and jacket

The Lenzing Group has created an innovative concept that contributes to the sustainable protection of our glaciers while inspiring collective action for sustainable practices and a circular economy in the nonwovens and textile value chain. The concept, which was artistically staged by the Italian artist Michelangelo Pistoletto, was presented on March 21, 2024, as part of the International Day of Forests celebrations at the Palais des Nations, the headquarters of the United Nations Office at Geneva (UNOG).

The melting of glaciers is being severely impacted by global warming. Geotextiles are used to protect ice and snow. However, the nonwovens used for this are made of fossil-based fibers, which allow microplastics1 to enter the valley via streams and may enter the food chain through small organisms and animals. Nonwovens made from cellulosic LENZING™ fibers, which are biodegradable at the end of their life cycle and can be completely recycled, are the sustainable solution to this problem.

Nonwovens made from cellulosic LENZING™ fibers, which are biodegradable at the end of their life cycle and can be completely recycled, are the sustainable solution to this problem.

The covering of a small area with the new material made from LENZING™ fibers was tested for the first time during a field test on the Stubai Glacier. Four meters of ice were saved from melting. This was confirmed in a study conducted by the University of Innsbruck and the Austrian glacier lift operators on the Stubai Glacier in Tyrol (Austria). In 2023, the pilot project was successfully extended to all Austrian glaciers used by tourists.

Last year, the project was also awarded first place in the prestigious Swiss BIO TOP Awards for wood and material innovations.

Lenzing takes this innovation project as an opportunity to inspire collaborative action towards sustainable practices and circularity in the textile value chain. Together with a network of innovative partners, Lenzing is working on processing geotextiles into new textile fibers giving them a second life as a garment. The use of geotextiles is usually limited to two years, after which the nonwovens would be disposed of. In the first phase of the pilot project, the recycling of nonwovens made for geotextiles use has been successfully tested and a fashionable “Glacier Jacket” has been produced, showcasing that the recycling of geotextiles is viable. Next to Lenzing, the network includes Marchi & Fildi Spa, a specialist in the field of mechanical recycling, the denim fabric manufacturer Candiani Denim and the fashion studio Blue of a Kind.

TMAS: Digitised solutions at Techtextil and Texprocess

Members of TMAS – the Swedish textile machinery association – will display technologies in alignment with the theme of digitalisation at the forthcoming Techtextil and Texprocess 2024 exhibitions, taking place in Frankfurt from April 23-26th.

Automatic handling
The fully automated and digitised handling solutions for finished garments, home textiles and furniture of Eton Systems, for example, will be demonstrated at Texprocess.

Designed to increase value-added time in production by eliminating manual transportation and minimising handling, the individually addressable product carriers are fully managed and controlled by the latest ETONingenious™ software. This web based real-time data collection and information system continuously accumulates, processes and makes all production information instantly available to supervisors, quality control personnel and management.

This web based real-time data collection and information system continuously accumulates, processes and makes all production information instantly available to supervisors, quality control personnel and management.

Bespoke seams
Svegea will demonstrate its EC 300-XS colarette technology, which is used by garment manufacturers around the world for the production of tubular apparel components such as cuff and neck tapes and other seam reinforcements.

The EC 300-XS collarette cutter on show in Frankfurt is equipped with the latest E-Drive II system providing the operator with a very user-friendly touchscreen, providing full control of the cutting process. An accompanying FA 350 fully automatic roll slitting machine will also be demonstrated.

Digital finishing
At Techtextil meanwhile, Baldwin Technology Co. will provide full details of how its highly digitised TexCoat G4 non-contact spray technology for textile finishing and remoistening not only reduces water, chemicals and energy consumption, but also provides the flexibility to adapt to customer requirements in terms of single and double-sided finishing applications.

TexCoat G4 can reduce water consumption and chemical usage by as much as 50% compared to traditional padding application processes.

Yarn tension
Celebrating its 60th anniversary this year, Eltex will display the latest Eltex EyETM system for the continuous monitoring of yarn tension on warp beams.

The Eltex EyETM eliminates problems when warping, and also in subsequent weaving or tufting processes, monitoring the yarn tension on all positions in real-time and enabling a minimum and maximum allowable tension value it be set. If any yarn’s tension falls outside these values the operator can be warned or the machine stopped.

The Eltex ACT and ACT-R units meanwhile go beyond yarn tension monitoring to actually control yarn tension. This extends the application range greatly. The plug and play system automatically compensates for any differences in yarn tension that arise, for example from irregularities in yarn packages.

Accumulated know-how
Vandewiele Sweden AB benefits from all of the synergies and accumulated know-how of Vandewiele Group, supplying weft yarn feeding and tension control units for weaving looms to the majority of weaving machine manufacturers. It also retrofits its latest technologies to working mills to enable instant benefits in terms of productivity and control.

The company will present its latest X4 yarn feeders with integrated accessory displays (TED) as a new standard, as well as launching its own e-commerce platform – iroonline.com.

The TED function enables weft tension settings to be transferred from one machine to another, enabling a fast start-up the next time the same article is woven. The position of the S-Flex Tensioner is constantly monitored by an internal sensor – even if adjustment is made during power off.

X4 feeders are also available with integrated active tension control (ATC-W) as an option. With the ATC-W active tension control, the required tension is easily set and monitored on the integrated display. Once set, the system constantly regulates itself, ensuring consistent yarn tension during the weaving process which is constantly and accurately measured by the ATC sensor unit, sending a signal to the ATC operator unit resulting in consistently stable yarn tension at the required level.

Biocarrier for green roofs
Freudenberg is showcasing a sustainable carrier material for green roofs on urban buildings at the trade fair. The carrier is made from polylactide, i.e. from renewable resources. When filled with soil, it provides a strong foothold to root systems, enabling the growth of lightweight sedum blankets that can be rolled out to provide instant green roofs. These roofs not only help counter urban heat, they also improve stormwater management and regulate indoor temperatures.

From textile waste to padding
The company extended its circular thermal wadding product range with the release of comfortemp® HO 80xR circular, a wadding made from 70 percent recycled polyamide from discarded fishing nets, carpet flooring and industrial plastic. Because polyamide 6, also known as nylon, retains its performance characteristics after multiple recycling processes, the fibers can be used again and again to manufacture performance sporting apparel, leisurewear and luxury garments.

Packaging solutions with various sustainability benefits
Freudenberg is also showcasing products for sustainable packaging and filtration solutions. The long-lasting Evolon® technical packaging series is a substitute for disposable packaging used in the transport of sensitive industrial items such as automotive parts. The material is made from up to 85 percent recycled PET. A further highlight at Techtextil are Freudenberg’s fully bio-based solutions for manufacturing dessicant bags.

Baldwin presents spray finishing system at Techtexil

Baldwin Technology Co. will join Elmatex GmbH at Techtexil (April 23-26 in Frankfurt, Germany) to demonstrate its TexCoat™ G4 precision spray finishing system.

Baldwin Technology Co. will join Elmatex GmbH at Techtexil (April 23-26 in Frankfurt, Germany) to demonstrate its TexCoat™ G4 precision spray finishing system.

With Baldwin’s system, the chemistry is precisely distributed across the textile surface and is applied only where it is required, on one or both sides of the fabric. The non-contact technology eliminates chemistry dilution in wet-on-wet processes, allowing full control of maintaining consistent chemistry coverage rates. Plus, pad bath contamination is eliminated, and changeovers are only required when there is a change of finish chemistry.
 
Furthermore, the system offers automated speed tracking, fabric-width compensation, and real-time monitoring to track system uptime, performance and chemistry usage, as well as active care alerts.
 
In addition, the TexCoat™ G4 system can process a wide range of low-viscosity water-based chemicals, such as durable water repellents, softeners, antimicrobials, flame retardants and more. Baldwin’s technology utilizes the same chemicals used in the traditional pad bath, and no special auxiliaries are required. The recipe is adjusted by increasing the concentration and reducing the pickup by a corresponding amount, so that the same level of solids is applied.
 
Some applications, such as durable water repellents, are only applied on the face of the fabric, instead of the traditional method of saturation through dipping and squeezing. Drier fabric entering the stenter means lower drying temperatures and faster process speeds. Single-side applications also open up the opportunity to process back-coated or laminated fabrics in a single pass of the stenter, instead of two passes.

European composites market on the level of 2014

After a long phase of continuous growth, the composites market has seen strong fluctuations since 2018. In 2023, the overall market for composites in Europe fell by 8%.

The current mood on the markets in Germany and Europe is rather negative within the industry. The main drivers are the persistently high energy and raw material prices. Added to this are problems in logistics chains and a cautious consumer climate. A slowdown in global trade and uncertainties in the political arena are fueling the negative sentiment. Despite rising registration figures, the automotive industry, the most important application area for composites, has not yet returned to its pre-2020 volume. The construction industry, the second key application area, is currently in crisis. These factors have already caused the Eu-ropean composites production volume to fall significantly in recent years. There has now been another decline in Europe for 2023.

There has now been another decline in Europe for 2023.

Overall development of the composites market
The volume of the global composites market totalled 13 million tons in 2023. Compared to 2022, with a volume of 12.3 million tons, growth was around 5%. In comparison, the European composites production volume fell by 8% in 2023. The total European composites market thus comprises a volume of 2,559 kilotons (kt) after 2,781 kt in 2022.

The market is therefore declining and falling back to the level of 2014. Overall, market momentum in Europe was lower than in the global market. Europe's share of the global market is now around 20%.

As in previous years, development within Europe is not uniform. The differences are due to very different regional core markets, the high variability of the materi-als used, a wide range of different manufacturing processes and widely differing areas of application. Accordingly, there are different regional trends, especially with regard to the individual processes, although there were declines in all re-gions and for almost all processes in 2023. At almost 50% of the market volume, the transportation sector accounts for the largest share of total composites pro-duction in terms of volume. The next two largest areas are the electri-cal/electronics sector and applications in construction and infrastructure.

DITF: Biopolymers from bacteria protect technical textiles

Textiles for technical applications often derive their special function via the application of coatings. This way, textiles become, for example wind and water proof or more resistant to abrasion. Usually, petroleum-based substances such as polyacrylates or polyurethanes are used. However, these consume exhaustible resources and the materials can end up in the environment if handled improperly. Therefore, the German Institutes of Textile and Fiber Research Denkendorf (DITF) are researching materials from renewable sources that are recyclable and do not pollute the environment after use. Polymers that can be produced from bacteria are here of particular interest.

Therefore, the German Institutes of Textile and Fiber Research Denkendorf (DITF) are researching materials from renewable sources that are recyclable and do not pollute the environment after use. Polymers that can be produced from bacteria are here of particular interest.

These biopolymers have the advantage that they can be produced in anything from small laboratory reactors to large production plants. The most promising biopolymers include polysaccharides, polyamides from amino acids and polyesters such as polylactic acid or polyhydroxyalkanoates (PHAs), all of which are derived from renewable raw materials. PHAs is an umbrella term for a group of biotechnologically produced polyesters. The main difference between these polyesters is the number of carbon atoms in the repeat unit. To date, they have mainly been investigated for medical applications. As PHAs products are increasingly available on the market, coatings made from PHAs may also be increasingly used in technical applications in the future.

The bacteria from which the PHAs are obtained grow with the help of carbohydrates, fats and an increased CO2 concentration and light with suitable wavelength.

The properties of PHA can be adapted by varying the structure of the repeat unit. This makes polyhydroxyalkanoates a particularly interesting class of compounds for technical textile coatings, which has hardly been investigated to date. Due to their water-repellent properties, which stem from their molecular structure, and their stable structure, polyhydroxyalkanoates have great potential for the production of water-repellent, mechanically resilient textiles, such as those in demand in the automotive sector and for outdoor clothing.

The DITF have already carried out successful research work in this area. Coatings on cotton yarns and fabrics made of cotton, polyamide and polyester showed smooth and quite good adhesion. The PHA types for the coating were both procured on the open market and produced by the research partner Fraunhofer IGB. It was shown that the molten polymer can be applied to cotton yarns by extrusion through a coating nozzle. The molten polymer was successfully coated onto fabric using a doctor blade. The length of the molecular side chain of the PHA plays an important role in the properties of the coated textile. Although PHAs with medium-length side chains are better suited to achieving low stiffness and a good textile handle, their wash resistance is low. PHAs with short side chains are suitable for achieving high wash and abrasion resistance, but the textile handle is somewhat stiffer.

The team is currently investigating how the properties of PHAs can be changed in order to achieve the desired resistance and textile properties in equal measure. There are also plans to formulate aqueous formulations for yarn and textile finishing. This will allow much thinner coatings to be applied to textiles than is possible with molten PHAs.

Other DITF research teams are investigating whether PHAs are also suitable for the production of fibers and nonwovens.

A project, designed to enhance RadiciGroup's transparency and commitment to develop a responsible business along its entire value chain from an economic, social and environmental perspective and focus on the ever more widespread and stringent sustainability regulatory requirements. These are the features and goals of the Sustainability Plan presented by the Group and called "From Earth to Earth", precisely to emphasize the intent to focus on the Earth and future generations.

“From Earth to Earth”: The new plan defines goals and concrete actions in Environmental, Social and Governance (ESG) areas to foster value creation for all stakeholders and put new sustainability regulatory requirements at the centre of attention.

A project, designed to enhance RadiciGroup's transparency and commitment to develop a responsible business along its entire value chain from an economic, social and environmental perspective and focus on the ever more widespread and stringent sustainability regulatory requirements. These are the features and goals of the Sustainability Plan presented by the Group and called "From Earth to Earth", precisely to emphasize the intent to focus on the Earth and future generations.

In the context of a complex and constantly changing scenario, the Group has therefore decided to capitalize on the goals achieved and look beyond them with a plan defining the medium-term targets and the actions to be taken to fulfil them and covering all areas considered to be "material”, i.e., relevant from the point of view of ESG and financial risks, opportunities and impacts. Indeed, the ultimate goal of "From Earth to Earth" is to support business continuity and the growth of the company and all its stakeholders.

The project was the result of a multi-year collaboration with Deloitte, which contributed an external and objective viewpoint on the definition of the material targets and themes. However, it was not an armchair exercise, but the result of an extensive listening process involving internal and external stakeholders, all of whom were sustainability experts who helped define a shortlist of strategic themes for both the Group and its main stakeholders. These issues were then analysed in detail using working tables on the different themes to identify the objectives in Environmental, Social and Governance areas and the related concrete actions needed to achieve them, in line with the European decarbonization and energy transition policies and the
United Nations Sustainable Development Goals, a global blueprint for sustainable growth.

In particular, RadiciGroup’s environmental goals include: a 20% increase and differentiation in renewable source electricity consumption, an 80% reduction in total direct greenhouse gas emissions by 2030 compared to 2011, attention to water consumption to limit the impact on local communities and biodiversity, the extension of Life Cycle Assessment (LCA) methodology to measure the environmental impact of 70% of the products (in terms of weight) manufactured by the entire Group, collaboration among the various actors in the supply chain from an ecodesign perspective and the search for increasingly more sustainable and circular packaging solutions.

The nominees:

The Straw Flexi-Dress: Design Meets Sustainability – DITF & VRETENA (DE)
The Flexi-Dress design was inspired by the natural golden colour and silky touch of HighPerCell® (HPC) filaments based on unbleached straw pulp. These cellulose filaments are produced using environmentally friendly spinning technology in a closed-loop production process. The design decisions focused on the emotional connection and attachment to the HPC material to create a local and circular fashion product. The Flexi-Dress is designed as a versatile knitted garment – from work to street – that can be worn as a dress, but can also be split into two pieces – used separately as a top and a straight skirt. The top can also be worn with the V-neck front or back. The HPC textile knit structure was considered important for comfort and emotional properties.

HONEXT® Board FR-B (B-s1, d0) – Flame-retardant Board made From Upcycled Fibre Waste From the Paper Industry – Honext Material (ES)
HONEXT® FR-B board (B-s1, d0) is a flame-retardant board made from 100 % upcycled industrial waste fibres from the paper industry. Thanks to innovations in biotechnology, paper sludge is upcycled – the previously “worthless” residue from paper making – to create a fully recyclable material, all without the use of resins. This lightweight and easy-to-handle board boasts high mechanical performance and stability, along with low thermal conductivity, making it perfect for various applications in all interior environments where fire safety is a priority. The material is non-toxic, with no added VOCs, ensuring safety for both people and the planet. A sustainable and healthy material for the built environment, it achieves Cradle-to-Cradle Certified GOLD, and Material Health CertificateTM Gold Level version 4.0 with a carbon-negative footprint. Additionally, it is verified in the Product Environmental Footprint.

LENZING™ Cellulosic Fibres for Glacier Protection – Lenzing (AT)
Glaciers are now facing an unprecedented threat from global warming. Synthetic fibre-based geotextiles, while effective in slowing down glacier melt, create a new environmental challenge: microplastics contaminating glacial environments. The use of such materials contradicts the very purpose of glacier protection, as it exacerbates an already critical environmental problem. Recognizing this problem, the innovative use of cellulosic LENZING™ fibres presents a pioneering solution. The Institute of Ecology, at the University of Innsbruck, together with Lenzing and other partners made first trials in 2022 by covering small test fields with LENZING™ fibre-based geotextiles. The results were promising, confirming the effectiveness of this approach in slowing glacier melt without leaving behind microplastic.

The RENU Jacket – Advanced Recycling for Cellulosic Textiles – Pangaia (UK) & Evrnu (US)
PANGAIA LAB was born out of a dream to reduce barriers between people and the breakthrough innovations in material science. In 2023, PANGAIA LAB launched the RENU Jacket, a limited edition product made from 100% Nucycl® – a technology that recycles cellulosic textiles by breaking them down to their molecular building blocks, and reforming them into new fibres. This process produces a result that is 100% recycled and 100% recyclable when returned to the correct waste stream – maintaining the strength of the fibre so it doesn’t need to be blended with virgin material.
Through collaboration with Evrnu, the PANGAIA team created the world’s first 100% chemically recycled denim jacket, replacing a material traditionally made from 100% virgin cotton. By incorporating Nucycl® into this iconic fabric construction, dyed with natural indigo, the teams have demonstrated that it’s possible to replace ubiquitous materials with this innovation.

Textiles Made from Easy-to-dye Biocelsol – VTT Technical Research Centre of Finland (FI)
One third of the textile industry’s wastewater is generated in dyeing and one fifth in finishing. But the use of chemically modified Biocelsol fibres reduces waste water. The knitted fabric is made from viscose and Biocelsol fibres and is only dyed after knitting. This gives the Biocelsol fibres a darker shade, using the same amount of dye and no salt in dyeing process. In addition, an interesting visual effect can be achieved. Moreover, less dye is needed for the darker colour tone in the finished textile and the possibility to use the salt-free dyeing is more environmentally friendly.
These special properties of man-made cellulosic fibres will reassert the fibres as a replacement for the existing fossil-based fibres, thus filling the demand for more environmentally friendly dyeing-solutions in the textile industry. The functionalised Biocelsol fibres were made in Finnish Academy FinnCERES project and are produced by wet spinning technique from the cellulose dope containing low amounts of 3-allyloxy-2-hydroxypropyl substituents. The functionality formed is permanent and has been shown to significantly improve the dyeability of the fibres. In addition, the functionalisation of Biocelsol fibres reduces the cost of textile finishing and dyeing as well as the effluent load.

A New Generation of Bio-based and Resource-efficient Fibre – TreeToTextile (SE)
TreeToTextile has developed a unique, sustainable and resource efficient fibre that doesn't exist on the market today. It has a natural dry feel similar to cotton and a semi-dull sheen and high drape like viscose. It is based on cellulose and has the potential to complement or replace cotton, viscose and polyester as a single fibre or in blends, depending on the application.
TreeToTextile Technology™ has a low demand for chemicals, energy and water. According to a third party verified LCA, the TreeToTextile fibre has a climate impact of 0.6 kg CO2 eq/kilo fibre. The fibre is made from bio-based and traceable resources and is biodegradable.

Both Knitwear Lab sites each have five STOLL flat knitting machines, including models from the modern ADF range. Prototypes are produced in Almere and there is small-scale production. The production plant in Istanbul specializes in the manufacture of high-quality knitwear in small quantities. STOLL is also involved in the creative processes. For the industrial development of knitwear, Knitwear Lab offers Virtual Knitting, a revolutionary method that combines virtual and physical elements of pattern development and knitwear production to reduce waste and pre-production steps. Customers can use Virtual Knitting to create realistic, producible collections, simplify their design iteration processes and take advantage of the wide range of real-life colorways. The basis for this is comprehensive knitwear expertise, the latest 3D software and the CREATE PLUS patterning software, which was developed by STOLL together with KM.ON.

"The 3D visualization of CREATE simplifies communication with the customer considerably. We use this function every day," says Annika Klaas, Senior Knitwear Programmer. She personally appreciates the uncomplicated grading and exchange of stitch dimensions and the much faster and more efficient work with Dimensioned Shapes that this makes possible. This helps her in her day-to-day work. "We often have requests to realize the same product in different yarns, which now works much faster," says the programmer. Further simplifications would include minor optimizations in terms of the efficiency and user-friendliness of programming and additional import and export options for shapes. Discussions on implementation are already underway.

New sustainability label Autoneum Blue

With its new sustainability label Autoneum Blue, Autoneum combines the use of recycled materials with protecting the oceans and social responsibility. Autoneum Blue is a continuation of the LABEL blue by Borgers®, which was originally launched by Borgers Automotive. Following the acquisition of the German automotive supplier in April 2023, Autoneum has now fully integrated the label into its sustainable product portfolio.

Following the acquisition of the German automotive supplier in April 2023, Autoneum has now fully integrated the label into its sustainable product portfolio.

Marine pollution has reached alarming levels in recent decades, with plastic contamination posing one of the most harmful threats to the health of the world’s largest ecosystem. In light of ever-stricter legal requirements for the environmental performance of vehicles, especially regarding the recycled content of components and their end-of-life recyclability, the reduction and recycling of plastics is also one of the key challenges for the automotive industry. Autoneum Pure, the Company’s sustainability label for technologies with an excellent sustainability performance throughout the product life cycle, is already successfully helping customers to tackle these challenges. With Autoneum Blue, Autoneum is now expanding its sustainable product portfolio with a label for components that combine the use of recycled material with protecting the oceans and social responsibility.

In order to qualify for the Autoneum Blue label, components must be based on materials that consist of at least 30% recycled PET that was collected from coastal areas within a 50-kilometer range of the water. These credentials mean the products make an important contribution to preventing plastic pollution in the oceans. In addition, the process of collecting the PET bottles must be socially respon-sible and comply with human rights, and traceable procurement of the bottle flakes must be guaran-teed. Autoneum Blue thus complements the Company’s strategic target to continuously reduce water consumption in all areas of its operations with an additional focus on preventing plastic pollution of the oceans.

Autoneum currently offers selected wheelhouse outer liners, needlepunch carpets and trunk side trim under the Blue label. In principle, however, the label could be extended to any product based on Autoneum technologies that feature recycled polyester fibers. As an addition to Autoneum’s existing fully recyclable monomaterial polyester constructions, which are characterized by waste-free production and have a significantly lower carbon footprint compared to products made from virgin fibers, Autoneum Blue presents another example of the Company’s ongoing efforts and continuous strides towards a sustainable circular economy.

Hologenix: CELLIANT® as a printed coating

Hologenix has announced that its flagship product CELLIANT® infrared (IR) technology, a natural blend of IR-generating bioceramic minerals, is now more widely available from the company as a printed coating, expanding the uses of the technology and increasing the number of prospective partners. The innovation has already been named a Selection in the Fibers & Insulations Category of the ISPO Textrends Awards just last month.

Traditionally, CELLIANT has been embedded directly into fibers and yarns. However, for its print applications, CELLIANT fine mineral powder can be easily added directly onto the surface of all different fabric types. The company is particularly energized about how this expands the array of sustainable offerings that CELLIANT can be incorporated into, and is looking forward to partnering with brands to print CELLIANT on their ecofriendly fabrics. CELLIANT Print may be a cost-effective alternative to in-yarn solutions and allows for a more efficient supply chain.

fabrics or to a new fabric to create a variety of different product applications. For brands who are seeking a smaller pattern roller for apparel, orthopedic products or other close-to-skin projects, CELLIANT Print can accommodate this. There is also a larger pattern roller for bedding and larger-scale applications. As long as the print covers 80% of the fabric’s surface, the design possibilities for the print itself are virtually endless. CELLIANT Print has undergone mechanical testing for wash tests and can be confirmed to last the useful life of the product, for 50+ washes.

By applying CELLIANT Print directly onto the fabric, brand partners are able to use CELLIANT with a higher loading of bioceramic minerals than what would otherwise be possible with an in-yarn solution. This makes it ideal for recovery and performance purposes. In fact, an example of a CELLIANT Print application on kinesiology tape, KT Tape® PRO Oxygen™ was launched in April to great success.

Self-driven and sustainable removal of oil spills in water using textiles

Researchers at the ITA, the University of Bonn and Heimbach GmbH have developed a new method for removing oil spills from water surfaces in an energy-saving, cost-effective way and without the use of toxic substances. The method is made possible by a technical textile that is integrated into a floating container. A single small device can remove up to 4 liters of diesel within an hour. This corresponds to about 100 m2 of oil film on a water surface.
 
Despite the steady expansion of renewable energies, global oil production, oil consumption and the risk of oil pollution have increased steadily over the last two decades. In 2022, global oil production amounted to 4.4 billion tons! Accidents often occur during the extraction, transportation and use of oil, resulting in serious and sometimes irreversible environmental pollution and harm to humans.

There are various methods for removing this oil pollution from water surfaces. However, all methods have various shortcomings that make them difficult to use and, in particular, limit the removal of oil from inland waters.

In 2022, global oil production amounted to 4.4 billion tons!

There are various methods for removing this oil pollution from water surfaces. However, all methods have various shortcomings that make them difficult to use and, in particular, limit the removal of oil from inland waters.

For many technical applications, unexpected solutions come from the field of biology. Millions of years of evolution led to optimized surfaces of living organisms for their interaction with the environment. Solutions - often rather unfamiliar to materials scientists and difficult to accept. The long-time routine examination of around 20,000 different species showed that there is an almost infinite variety of structures and functionalities. Some species in particular stand out for their excellent oil adsorption properties. It was shown that, e.g., leaves of the floating fern Salvinia molesta, adsorb oil, separate it from water surfaces and transport it on their surfaces (Figure 1, see also the video of the phenomon.).

The observations inspired them to transfer the effect to technical textiles for separating oil and water. The result is a superhydrophobic spacer fabric that can be produced industrially and is therefore easily scalable.

The bio-inspired textile can be integrated into a device for oil-water separation. This entire device is called a Bionic Oil Adsorber (BOA). Figure 2: Cross-section of computer-aided (CAD) model of the Bionic Oil Adsorber. The scheme shows an oil film (red) on a water surface (light blue). In the floating cotainer(gray), the textile (orange) is fixed so that it is in contact with the oil film and the end protrudes into the container. The oil is adsorbed and transported by the BOA textile. As shown in the cross-section, it enters the contain-er, where it is released again and accumulates at the bottom of the container. See also the video regarding the oil absorption on the textile, source ITA).
 
Starting from the contamination in the form of an oil film on the water surface, the separation and collection process works according to the following steps:

  • The BOA is introduced into the oil film.
  • The oil is adsorbed by the textile and separated from the water at the same time.
  • The oil is transported through the textile into the collection container.
  • The oil drips from the textile into the collection container.
  • The oil is collected until the container is emptied.

The advantage of this novel oil separation device is that no additional energy has to be applied to operate the BOA. The oil is separated from the surrounding water by the surface properties of the textile and transported through the textile driven solely by capillary forces, even against gravity. When it reaches the end of the textile in the collection container, the oil desorbs without any further external influence due to gravitational forces. With the current scale approximately 4 L of diesel can be separated from water by one device of the Bionic Oil Adsorber per hour.

  • It seems unlikely that a functionalized knitted spacer textile is cheaper than a conventional nonwoven, like it is commonly used for oil sorbents. However, since it is a functional material, the costs must be related to the amount of oil removed. In this respect, if we compare the sales price of the BOA textile with the sales prices of various oil-binding nonwovens, the former is 5 to 13 times cheaper with 10 ct/L oil removed.
    Overall, the BOA device offers a cost-effective and sustainable method of oil-water separation in contrast to conventional cleaning methods due to the following advantages:
  • No additional energy requirements, such as with oil skimmers, are necessary
  • No toxic substances are introduced into the water body, such as with oil dispersants
  • The textiles and equipment can be reused multiple times
  • No waste remains inside the water body
  • Inexpensive in terms of the amount of oil removed.
  • The team of researchers from the ITA, the University of Bonn and Heimbach GmbH was able to prove that the novel biomimetic BOA technology is surprisingly efficient and sustainable for a self-controlled separation and automatic collection of oil films including their complete removal from the water. BOA can be asapted for open water application but also for the use in inland waters. Furthermore, it is promising, that the textile can be used in various related separation processes. The product is currently being further developed so that it can be launched on the market in 2-3 years.

Optimized acoustic performance thanks to sustainable technology with high recycled content

Autoneum’s sustainable, textile and lightweight Propylat technology reduces both interior and exterior noise of vehicles. Propylat was originally developed by Borgers Automotive, which was acquired by Autoneum in April 2023. The versatile technology is characterized by a flexible material composition of natural and synthetic fibers with a high recycled content and contributes to significant waste reduction thanks to its complete vertical integration. In addition, the fully recyclable technology variant Propylat PET is now part of the sustainability label Autoneum Pure.

In addition, the fully recyclable technology variant Propylat PET is now part of the sustainability label Autoneum Pure.

The ongoing electrification of mobility as well as increasingly strict regulatory requirements for vehicle performance in terms of sustainability and acoustics are presenting new challenges to car manufacturers worldwide. With Propylat, Autoneum now offers another lightweight, fiber-based and versatile technology whose sound-insulating and -absorbing properties as well as high content of recycled materials help customers address these challenges. Propylat-based products not only contribute to reducing pass-by noise and improving driver comfort, but they are also up to 50 percent lighter than equivalent plastic alternatives; this results in a lower vehicle weight and, consequently, less fuel and energy consumption as well as lower CO2 emissions.

Autoneum's innovative Propylat technology consists of a mixture of recycled synthetic and natural fibers – the latter include cotton, jute, flax or hemp, for example – that are consolidated using thermoplastic binding fibers without adding any further chemical binders. Thanks to the flexible fiber composition and the variable density and thickness of the porous material, the properties of the respective Propylat variant, for example with regards to acoustic performance, can be tailored to individual customer requirements. This allows for a versatile application of the technology in a variety of interior and exterior components such as wheelhouse outer liners, trunk trim, underbody systems and carpets. For instance, Propylat-based wheelhouse outer liners significantly reduce rolling noise both inside and outside the vehicle while at the same time offering optimum protection against stone chipping and spray water.

In terms of sustainability, Propylat always contains a high proportion of recycled fibers – up to 100% in some variants – and can be manufactured with zero waste. Thanks to the full vertical integration of Propylat and Autoneum’s extensive expertise in recycling processes, the technology also contributes to a further significant reduction in production waste. Moreover, the Propylat PET technology variant, which consists of 100% PET, of which up to 70% are recycled fibers, is fully recyclable at the end of product life. For this reason, Propylat PET has been selected for Autoneum Pure – the Company’s sustainability label for technologies with excellent environmental performance throughout the product life cycle – where it will replace the current Mono-Liner technology going forward.

Propylat-based components are currently available in Europe, North America and China.
