RadiciGroup: a Physical and digital nylon traceability

RadiciGroup announced the launch of the first physical and digital nylon traceability project at Techtextil 2024. A gilet made from the yarn manufactured in one of the Group’s European industrial sites, which, thanks to a QR code on the garment, can reveal its origin and display information about its production process.

Product traceability is a key element in guaranteeing transparency along the entire supply chain, as it means each stage of production – from spinning to weaving and from packaging through to retail – can be monitored and recorded. The project, made possible by a partnership with FibreTrace, allows manufactured nylon yarns to be traced both physically and digitally. In fact, RadiciGroup inserts a tracer (an inorganic additive) that is uniquely associated with the yarn and remains identifiable throughout all stages of processing – on both the fabric and the finished garment. Naturally, the tracer does not alter the esthetical, functional and technical performance of the yarns in any way.

In terms of digital traceability, during the production stages a scanner detects the presence of the tracer and can transmit the data relating to provenance onto a dedicated digital platform. Finally, the consumer, via a QR code, can access the digital platform that provides all information concerning the provenance of the product and its journey through the supply chain.
 
“This project is the result of almost two years’ work by our Research & Development team. We’re very proud to bring to the market the first physical and digital nylon traceability solution and we plan to extend this initiative to other fibres produced by the Group,” emphasised Filippo Bona, R&D Manager of RadiciGroup Advanced Textile Solutions.

California’s Largest Sewage Collection Study Photo: INDA

California’s Largest Sewage Collection Study: Wipes Clogging the Pipes?

In accordance with California’s Proper Labeling of Wet Wipes law (AB 818), state wastewater agencies and industry experts went deep to find out exactly what is passing through—and clogging up—municipal wastewater systems. The Responsible Flushing Alliance (RFA) alongside the California Association of Sanitation Agencies (CASA) and the Association of the Nonwoven Fabrics Industry (INDA) released the results from the largest known domestic sewage collection study conducted to reveal what’s really being flushed down the drain – and shouldn’t be.

“We took a forensic approach to this collection study, engaging industry and wastewater experts to examine our findings and determine what exactly is being flushed and how much of it,” said Adam Link, Executive Director at CASA, a co-sponsor of the Proper Labeling of Wet Wipes Law. “Now that we have the data to see what Californians are flushing and the types of non-flushable items that are causing issues within wastewater systems, local agencies can refine their public outreach and messaging to target specific problems and educate more efficiently.”

“We took a forensic approach to this collection study, engaging industry and wastewater experts to examine our findings and determine what exactly is being flushed and how much of it,” said Adam Link, Executive Director at CASA, a co-sponsor of the Proper Labeling of Wet Wipes Law. “Now that we have the data to see what Californians are flushing and the types of non-flushable items that are causing issues within wastewater systems, local agencies can refine their public outreach and messaging to target specific problems and educate more efficiently.”

Collection and material investigation took place in October 2023 at two locations: Inland Empire Utilities Agency (IEUA) in Southern California and Central Contra Costa Sanitary District (Central San) in the greater San Francisco Bay Area in Northern California. Wastewater and wipes experts collected, sorted and identified more than 1,700 items pulled from the two locations during peak flow times. Kennedy Jenks, an independent engineering firm, designed the study and compiled the findings into the report.

Why Study What’s Being Flushed?
When products that aren’t meant to be flushed down the toilet wind up in the sewer system, it can cause serious threats to public and environmental health. In fact, estimates show that local public agencies throughout California (and the ratepayers they represent) are spending more than $47 million annually to repair wastewater treatment equipment and respond to sewer overflows caused by improper flushing.

“Part of keeping communities healthy requires not flushing things we shouldn’t,” said Lara Wyss, President of the RFA. “However, the data to support which non-flushable items to target as part of education campaigns has been lacking. That’s likely why when we surveyed Californians about what they are flushing, the results revealed that approximately 25% think baby wipes are flushable (which is never true) and 60% self-reported that they flushed something they knew they shouldn’t have.2 Our study results reinforce that finding, as more than 99% of materials collected were items that shouldn’t have been flushed.”

The breakdown of items collected from pipes at the two study locations included:
•    34.1% wipes labeled with the “Do Not Flush” symbol (baby wipes, cleaning wipes, makeup wipes, etc.)
•    64.9% other non-flushable items (paper towels, period products, trash, etc.)
•    0.9% wipes labeled as flushable

“We pulled material larger than 1-inch square directly from the bar screens, and it wasn’t until everything was sorted and identified that we could see what we actually had,” said Matt O’Sickey, Director of Education and Technical Affairs, INDA. “There were a lot of paper towels and baby wipes and all of the ‘Do Not Flush’ labeled wipes we collected were fully intact, showcasing why they should never be flushed.”

What Not to Flush—and How We Tell Consumers
According to the Proper Wet Wipes Labeling law, manufacturers of non-flushable wipes, including products such as baby wipes, cleaning wipes, makeup removal wipes and many others that are primarily used in a bathroom setting must include the “Do Not Flush” symbol on the front of the packaging.
The #FlushSmart consumer education campaign promotes the “Do Not Flush” symbol and provides information on what should and should not be flushed. The message shared with consumers is simple: Look for the “Do Not Flush” symbol on wipes packaging, and if you see it – throw the wipe out. Extrapolating from the results of this study, refraining from flushing “Do Not Flush” labeled wipes, paper products and feminine hygiene products would capture over 90% of items clogging sewers.

Trützschler: Holistic approach to textile recycling

Trützschler expanded their portfolio to become the first full-liner in the preparation of textile waste – from mechanical recycling to the spinning preparation of torn secondary fibers.

The TRUECYCLED solution is the result of their cooperation with the company Balkan Textile Machinery INC.CO. in Turkey, which they announced at the ITMA 2023 trade event in Milan. Since then, Trützschler has received many inquiries for recycling systems.

The TRUECYCLED solution is the result of their cooperation with the company Balkan Textile Machinery INC.CO. in Turkey, which they announced at the ITMA 2023 trade event in Milan. Since then, Trützschler has received many inquiries for recycling systems.

Success with a systems approach
Recycling systems face significant technological challenges. On average, torn fibers are much shorter than virgin fibers. The percentage share of short fibers in the fiber mass is much higher. Unopened yarn and fabric particles are also difficult to process. Not surprisingly, much academic and practical research is currently conducted to find solutions for these problems. Dr. Georg Stegschuster, a researcher specializing in textile recycling, believes a systems approach is needed. He is working at the Recycling atelier, a model factory for mechanical recycling in Augsburg, Germany, which is committed to delivering the latest technological insights for textile recycling. “A perfect fine-tuning between tearing and spinning preparation is key for obtaining the best possible quality results and avoiding unnecessary fiber shortening,” he says. “This can be achieved if you are in control of both processes – and have the necessary expertise for both processes too.”

Gentle but effective
In some cases, for example, it may be advantageous to have less aggressive settings in the tearing line. This can help avoid unnecessary fiber shortening. The remaining higher share of unopened fabric must then be handled in a high-performance spinning preparation line. This starts with the right blow room configuration for perfect opening, cleaning and blending. A card that is specially designed for recycling materials, such as the new TC 30Ri, can also enable gentle but effective treatment of fibers.

A shortened drafting process is also a must. The integrated draw frame IDF 3 can make this possible. The draft is high enough to provide excellent levelling of the numerous short fibers, but low enough to prevent floating fibers.

Full-liner in mechanical recycling and preparation of textile waste
Trützschler now offers a complete system covering the whole process, from cutting and tearing textile waste through to carding and drawing secondary fibers. Thanks to this holistic approach and Trützschler’s expertise for the whole process, manufacturers can avoid unnecessary fiber shortening.

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.

HEREWEAR is winner of the Cellulose Fibre Innovation of the Year

At the "International Conference on Cellulose Fibers 2024" in Cologne, Germany, the Nova Institute for Ecology and Innovation awarded first place in the Innovation Prize to the project partners of the EU-funded HEREWEAR project. They presented a dress made of cellulose fibers, which is entirely made of straw pulp.

HEREWEAR is an EU-wide research project that brings together partners from research and industry. They are working to establish a European circular economy for locally produced textiles and clothing made from bio-based raw materials.
The HEREWEAR consortium consists of small and medium-sized enterprises and research institutions. HEREWEAR covers all the necessary expertise and infrastructure from academic and applied research and industry from nine EU countries.

The HEREWEAR approach includes technical and ecological innovations in the production of fibers, yarns, fabrics, knitwear and garments, as well as the use of regional value chains and the circular development of fashion items.

The HEREWEAR approach includes technical and ecological innovations in the production of fibers, yarns, fabrics, knitwear and garments, as well as the use of regional value chains and the circular development of fashion items.

New technologies for wet and melt spinning of cellulose and bio-based polyesters, e.g. PLA, from which yarns and fabrics are produced, form the technical basis. Coating and dyeing processes have been developed and tested as part of the project. In addition to reducing the carbon footprint of the product, another environmental goal is to reduce the release of microfibers throughout the textile manufacturing process and life cycle.

Improving the sustainability and recyclability of the developed garments is ensured by design for circularity and digitally networked production means. On-demand production is realized in so-called "microfactories", which are individualized and produce only for actual demand. This production method can be achieved through regional, networked value chains and enables the traceability of materials and manufacturing processes.

The dress presented at the award ceremony is an example of the cooperation and the different qualifications of the project partners: TNO (Netherlands Organization for Applied Scientific Research) provided sustainably produced pulp. The HighPerCell fibers were produced in DITF's spinning facilities. At the same time, designers from the fashion label Vretena created the design for the flexible, two-piece dress, which can be knitted without cutting waste. DITF textile experts worked with the designers to develop the knitting pattern. DITF textile engineers and technicians produced the knitted fabric and assembled the dress at the institutes’ technical center. DITF computer scientists and engineers created the "value chain" and "digital twins" for digital traceability of the production processes.

The innovation prize was awarded to the HEREWEAR consortiu for their joint achievement. Representatives of DITF Denkendorf and Vretena accepted the award on behalf of the EU project partners.

DITF: CO2-negative construction with new composite material

The DITF is leading the joint project "DACCUS-Pre*". The basic idea of the project is to develop a new building material that stores carbon in the long term and removes more CO2 from the atmosphere than is emitted during its production.       

In collaboration with the company TechnoCarbon Technologies, the project is now well advanced - a first demonstrator in the form of a house wall element has been realized. It consists of three materials: Natural stone, carbon fibers and biochar. Each component contributes in a different way to the negative CO2 balance of the material:

Two slabs of natural stone form the exposed walls of the wall element. The mechanical processing of the material, i.e. sawing in stone cutting machines, produces significant quantities of stone dust. This is very reactive due to its large specific surface area. Silicate weathering of the rock dust permanently binds a large amount of CO2 from the atmosphere.

In collaboration with the company TechnoCarbon Technologies, the project is now well advanced - a first demonstrator in the form of a house wall element has been realized. It consists of three materials: Natural stone, carbon fibers and biochar. Each component contributes in a different way to the negative CO2 balance of the material:

Two slabs of natural stone form the exposed walls of the wall element. The mechanical processing of the material, i.e. sawing in stone cutting machines, produces significant quantities of stone dust. This is very reactive due to its large specific surface area. Silicate weathering of the rock dust permanently binds a large amount of CO2 from the atmosphere.

Carbon fibers in the form of technical fabrics reinforce the side walls of the wall elements. They absorb tensile forces and are intended to stabilize the building material in the same way as reinforcing steel in concrete. The carbon fibers used are bio-based, produced from biomass. Lignin-based carbon fibers, which have long been technically optimized at DITF Denkendorf, are particularly suitable for this application: They are inexpensive due to low raw material costs and have a high carbon yield. In addition, unlike reinforcing steel, they are not susceptible to oxidation and therefore last much longer. Although carbon fibers are more energy-intensive to produce than steel, as used in reinforced concrete, only a small amount is needed for use in building materials. As a result, the energy and CO2 balance is much better than for reinforced concrete. By using solar heat and biomass to produce the carbon fibers and the weathering of the stone dust, the CO2 balance of the new building material is actually negative, making it possible to construct CO2-negative buildings.

The third component of the new building material is biochar. This is used as a filler between the two rock slabs. The char acts as an effective insulating material. It is also a permanent source of CO2 storage, which plays a significant role in the CO2 balance of the entire wall element.

From a technical point of view, the already realized demonstrator, a wall element for structural engineering, is well developed. The natural stone used is a gabbro from India, which has a high-quality appearance and is suitable for high loads. This has been proven in load tests.  Bio-based carbon fibers serve as the top layer of the stone slabs. The biochar from Convoris GmbH is characterized by particularly good thermal insulation values.

The CO2 balance of a house wall made of the new material has been calculated and compared with that of conventional reinforced concrete. This results in a difference in the CO2 balance of 157 CO2 equivalents per square meter of house wall. A significant saving!

STFI: Lightweight construction innovations at JEC World in Paris

At this year's JEC World, STFI will be presenting highlights from carbon fibre recycling as well as a new approach to hemp-based bast fibres, which have promising properties as reinforcement in lightweight construction.

Green Snowboard
At JEC World in Paris from 5 to 7 March 2024, STFI will be showcasing a snowboard from silbaerg GmbH with a patented anisotropic coupling effect made from hemp and recycled carbon fibres with bio-based epoxy resin. In addition to silbaerg and STFI, the partners Circular Saxony - the innovation cluster for the circular economy, FUSE Composite and bto-epoxy GmbH were also involved in the development of the board. The green snowboard was honoured with the JEC Innovation Award 2024 in the “Sport, Leisure and Recreation” category.

VliesComp
The aim of the industrial partners Tenowo GmbH (Hof), Siemens AG (Erlangen), Invent GmbH (Braunschweig) and STFI united in the VliesComp project is to bring recycled materials back onto the market in various lightweight construction solutions. The application fields "Innovative e-machine concepts for the energy transition" and "Innovative e-machine concepts for e-mobility" were considered as examples. On display at JEC World in Paris will be a lightweight end shield for electric motors made from hybrid nonwovens - a mixture of thermoplastic fibre components and recycled reinforcing fibres - as well as nonwovens with 100% recycled reinforcing fibres. The end shield was ultimately manufactured with a 100% recycled fibre content. The tests showed that, compared to the variant made from primary carbon fibres using the RTM process, a 14% reduction in CO2 equivalent is possible with the same performance. The calculation for the use of the prepreg process using a bio-resin system shows a potential for reducing the CO2 equivalent by almost 70 %.

Bast fibre reinforcement
To increase stability in the plant stem, bast fibres form in the bark area, which support the stem but, in contrast to the rigid wood, are very flexible and allow slender, tall plants to move in the wind without breaking.A new process extracts the bast bark from hemp by peeling.The resulting characteristic values, such as tensile modulus of elasticity, breaking strength and elongation, are very promising in comparison with the continuous rovings made of flax available on the market.The material could be used as reinforcement in lightweight construction.At JEC World, STFI will be exhibiting reinforcing bars that have been processed into a knitted fabric using a pultrusion process based on bio-based reinforcing fibres made from hemp bast for mineral matrices.

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.

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.

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.
