The German Institutes of Textile and Fiber Research Denkendorf (DITF) are coordinating the research project, which is funded as part of the European Union's Horizon Europe research and innovation program. The aim of BioFibreLoop is to develop recyclable outdoor and work clothing made from renewable bio-based materials. The kick-off event took place in Denkendorf on June 26 and 27, 2024.

The textile industry is facing two challenges: on the one hand, production must become more sustainable and environmentally friendly and, on the other, consumers are expecting more and more smart functions from clothing.

In addition, the production of functional textiles often involves the use of chemicals that are harmful to the environment and health and make subsequent recycling more difficult.

Intelligent innovations must therefore ensure that harmful chemicals are replaced, water is saved and more durable, recyclable bio-based materials are used, thereby reducing the usually considerable carbon footprint of textile products. Digitalized processes are intended to ensure greater efficiency and a closed cycle.

For example, the BioFibreLoop project uses laser technology to imitate natural structures in order to produce garments with water and oil-repellent, self-cleaning and antibacterial properties. At the end result of the research work will be affordable, resource and environmentally friendly, yet high-performance and durable fibers and textiles made from renewable sources such as lignin, cellulose and polylactic acid will be available. All processes are aimed at a circular economy with comprehensive recycling and virtually waste-free functionalization based on nature's example. In this way, greenhouse gas emissions could be reduced by 20 percent by 2035.

The technology for the functionalization and recycling of bio-based materials is being developed in three industrial demonstration projects in Austria, the Czech Republic and Germany. At the end of the project, a patented circular, sustainable and reliable process for the production of recyclable functional textiles will be established.

The BioFibreLoop project has a duration of 42 months and a total budget of almost 7 million euros, with 1.5 million going to the coordinator DITF.

The consortium consists of 13 partners from nine countries who contribute expertise and resources from science and industry:

• German Institutes of Textile and Fiber Research Denkendorf (DITF), Coordinator, Germany
• Next Technology Tecnotessile Società nazionale di ricerca R. L., Italy
• Centre Technologique ALPhANOV, France

The Lectra Group company announced a new collaboration between TextileGenesis, the textile traceability platform and the Forest Stewardship Council (FSC®). It will enable the implementation, via the TextileGenesis platform, of new solutions to ensure the traceability of cellulose fibers from responsibly managed forests.

In fashion, many textiles such as viscose, lyocell and modal use man-made cellulose fibers. These fibers are themselves made from wood pulp, the production of which can contribute to deforestation.

Founded in 1994, the Forest Stewardship Council (FSC®) is an international NGO whose mission is to promote responsible forest management worldwide. In particular, the organization offers certification for products and raw materials which have been obtained from wood grown in responsibly managed forests, and comes from supply chains where social rights of workers, communities and indigenous peoples have been safeguarded.

Amit Gautam, founder and CEO of TextileGenesis, explains: "We've already been working with Man Made Cellulosic Fiber Producers for several years to facilitate, thanks to our blockchain-inspired technology, the traceability of fibers manufactured by the most virtuous producers, and we've integrated their analysis criteria into our platform. By also becoming an FSC® partner today, we're taking things a step further. This new collaboration will support companies in the traceability of FSC certified fibers and support the administration and data management of FSC Chain of Custody certification. All players in the value chain will benefit from increased transparency and much more reliable upstream data. Fashion brands will be able to demonstrate much more easily that their garments use textiles made from responsibly sourced man-made cellulose fibers."

Fabian Farkas, FSC International Chief Commercial Director, adds: “We are seeing a rapid increase in interest in FSC certification from the textile industry, marking a very positive trend. Through this collaboration with TextileGenesis, we aim to simplify the administrative part of FSC certification for companies within the textile supply chain by automating many required data processes. Our goal is to empower brands to identify opportunities for seamless progress in meeting their FSC procurement policies.”

Following the signature in October 2023 of a memorandum of understanding with the International Cotton Association (ICA) and the launch last January of two consortiums with footwear and leather players, and more recently the announcement of its partnership with the Aid by Trade Foundation (AbTF), the initiator of The Good Cashmere Standard® (GCS), TextileGenesis confirms, with this new collaboration with the FSC®, its central place in the ecosystem of players mobilizing for more sustainable and responsible fashion.

INDA, the Association of the Nonwovens Fabrics Industry, announces the publication of the eleventh edition of the annual North American Nonwovens Supply Report.  

Based on extensive research, producer surveys and interviews with industry leaders, this report provides a comprehensive view of the North American supply of nonwoven materials including the key metrics of capacity, production and operating rates, and regional trade through 2023.

The Executive Summary from annual Supply Reports, the quarterly INDA Market Pulse and monthly Price Trends Summary are provided to INDA members on a complimentary basis as part of their membership. The data gathered for this annual report serves as the foundation for both the biennial Global Nonwoven Markets Report to be published in October 2024 and the biennial North American Nonwovens Industry Outlook, which was published in October 2023.

Findings from this year’s Supply Report include:

• North American capacity continues to increase with investments being made across all processes and for a variety of end-uses. Production output is shifting and has slowed down in 2023 to reflect larger machine installations just now coming on-line.
• In 2023, the capacity of nonwovens in North America reached 5.713 million tonnes, an increase from the previous year of over 230,000 tonnes.
• Many new nonwoven production lines were installed in 2023, but mostly in the long-life sectors which shows a positive move towards sustainable goals across the board.

As the 2024 edition of Techtextil, the leading international trade fair for technical textiles and nonwovens, gets underway in Frankfurt, Beaulieu Fibres International is introducing its Sustainable Fibres Program to help reshape fibres for sustainable solutions.

Through the initiative the company is looking to gain deeper insights into the challenges encountered by customers across the value chain to identify opportunities to leverage its expertise to deliver impactful products and services.

Beaulieu has identified several conversation triggers for Techtextil 2024, including recyclable, high performance, renewable, bio-circular, co-developed and made in Europe fibres, to find out what matters most to customers in terms of targets, green initiatives and sustainability expectations.
The Sustainable Fibres Program serves as a charter to help Beaulieu Fibres International accelerate its ‘fibres that build futures’ campaign, by educating on existing solutions, reshaping products and creating partnerships to facilitate market cooperation on shared challenges.

In addition to leading the market within the framework of the European Green Deal, and alignment with the objectives of the proposed Ecodesign for Sustainable Products Regulation, Beaulieu Fibres International is committed to achieving its own sustainability targets outlined in its roadmap known as ROUTE 2030.

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.

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.

The German Institutes of Textile and Fiber Research Denkendorf (DITF) have modernized and expanded their melt spinning pilot plant with support from the State of Baden-Württemberg. The new facility enables research into new spinning processes, fiber functionalization and sustainable fibers made from biodegradable and bio-based polymers.

In the field of melt spinning, the DITF are working on several pioneering research areas, for example the development of various fibers for medical implants or fibers made from polylactide, a sustainable bio-based polyester. Other focal points include the development of flame-retardant polyamides and their processing into fibers for carpet and automotive applications as well as the development of carbon fibers from melt-spun precursors. The development of a bio-based alternative to petroleum-based polyethylene terephthalate (PET) fibers into polyethylene furanoate (PEF) fibers is also new. Bicomponent spinning technology, in which the fibers can be produced from two different components, plays a particularly important role, too.

Since polyamide (PA) and many other polymers were developed more than 85 years ago, various melt-spun fibers have revolutionized the textile world. In the field of technical textiles, they can have on a variety of functions: depending on their exact composition, they can for example be electrically conductive or luminescent. They can also show antimicrobial properties and be flame-retardant. They are suitable for lightweight construction, for medical applications or for insulating buildings.

In order to protect the environment and resources, the use of bio-based fibers will be increased in the future with a special focus on easy-to-recycle fibers. To this end, the DITF are conducting research into sustainable polyamides, polyesters and polyolefins as well as many other polymers. Many 'classic', that is, petroleum-based polymers cannot or only insufficiently be broken down into their components or recycled directly after use. An important goal of new research work is therefore to further establish systematic recycling methods to produce fibers of the highest possible quality.

For these forward-looking tasks, a bicomponent spinning plant from Oerlikon Neumag was set up and commissioned on an industrial scale at the DITF in January. The BCF process (bulk continuous filaments) allows special bundling, bulking and processing of the (multifilament) fibers. This process enables the large-scale synthesis of carpet yarns as well as staple fiber production, a unique feature in a public research institute. The system is supplemented by a so-called spinline rheometer. This allows a range of measurement-specific chemical and physical data to be recorded online and inline, which will contribute to a better understanding of fiber formation. In addition, a new compounder will be used for the development of functionalized polymers and for the energy-saving thermomechanical recycling of textile waste.

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.

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.
