From the Sector

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.

CARBIOS, a pioneer in the development and industrialization of biological technologies to reinvent the life cycle of plastic and textiles, announces its membership to Paris Good Fashion, the association that unites over 100 French players in the sector - brands, designers and experts - around their commitment to sustainable fashion. CARBIOS is the first recycling technology supplier to join, demonstrating the importance given to recycling to achieve textile circularity. By contributing its solution for the biorecycling of polyester, the world's most widely used and fastest-growing textile fiber, CARBIOS aims to contribute Paris Good Fashion’s mission, which focuses on concrete actions, best practice sharing and collective intelligence to accelerate change in the fashion industry.

CARBIOS will be particularly involved in the association's project to set up a working group dedicated to the development of a "fiber-to-fiber" industry, one of Paris Good Fashion's top priorities over the next five years. While only 1% of textiles are currently recycled fiber-to-fiber (circular), this working group will identify levers for significantly increasing the share of recycled fibers in the industry.  Polyester currently follows a linear model from which we need to break out: virgin polyester is made from petroleum, and recycled polyester from PET bottles. After use, most of these products end their lives in landfill or incineration. A circular, "fiber-to-fiber" industry will give new life to textiles and reduce the environmental impact associated to their end-of-life management.

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.

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.

Kelheim Fibres is showcasing recent research findings at this year's Cellulose Fibres Conference (13rd-14th of March). The development, led by Dr. Ingo Bernt, Project Leader of Fibre & Application Development at Kelheim Fibres, and Dr. Thomas Harter from Graz University of Technology, provides insights into the correlation between the geometry of viscose fibres and the liquid absorption of tampons.

Kelheim Fibres has long been engaged in the functionalization of viscose fibres, including the specific adaptation of fibre cross-sections. The trilobal Galaxy® serves as an example. The current study underscores the properties of the fibre, primarily rooted in its geometry. This involves taking a closer look at the underlying mechanisms. It has been confirmed that, in contrast to the traditionally round viscose fibres and despite similar chemical compositions and mechanical properties, Galaxy® enables significantly better liquid absorption.

While the higher specific surface area of trilobal fibres already promotes improved liquid absorption, this is not the main factor accounting for the difference in absorption. Instead, the geometric shape of the fibres proves to be crucial. Trilobal fibres create and maintain a more voluminous, extensive network within the absorbent body, providing a larger volume for liquid absorption.

Dr. Ingo Bernt emphasizes, "The results of our study are not limited to tampons—any application requiring increased absorbency can benefit from the properties of our Galaxy® fibres."

The lecture "Geometry Matters: Unveiling Tampon Absorption Mechanisms" by Dr. Ingo Bernt und Dr. Thomas Harter takes place on the 14th of March at 2:50pm.

At this year's JEC World 2024 from 5 to 7 March, KARL MAYER GROUP will be exhibiting with KARL MAYER Technical Textiles and its STOLL Business

One focus of the exhibition will be non-crimp fabrics and tapes made from bio-based yarn materials for the reinforcement of composites.

"While our business with multiaxial and spreading technology for processing conventional technical fibres such as carbon or glass continues to do well, we are seeing increasing interest in the processing of natural fibres into composites. That's why we have a new product in our trade fair luggage for the upcoming JEC World: an alpine ski in which, among other things, hemp fibre fabrics have been used," reveals Hagen Lotzmann, Vice President Sales KARL MAYER Technische Textilien.

The winter sports equipment is the result of a subsidised project. The hemp tapes for this were supplied by FUSE GmbH and processed into non-crimp fabrics on the COP MAX 5 multiaxial warp knitting machine in the KARL MAYER Technical Textiles technical centre.

The STOLL Business Unit will be focussing on thermoplastic materials. Several knit to shape parts with a textile outer surface and a hardened inner surface will be on display. The double-face products can be made from different types of yarn and do not need to be back-moulded for use as side door panels or housing shells, for example. In addition, the ready-to-use design saves on waste and yarn material.

HeiQ AeoniQ Holding, a subsidiary of HeiQ Group, is appointing Julien Born as its CEO, leveraging his extensive executive leadership and profound textile industry expertise cultivated in prestigious organizations such as DuPont, KOCH Industries, and The LYCRA Company, where he served as CEO since 2021. Julien Born will champion the growth of the cellulosic filament fiber HeiQ AeoniQ™.

The HeiQ AeoniQ™ technology is poised for commercial production at the inaugural manufacturing facility in Portugal by the close of 2025.

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.

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.

Panda Biotech announced that building construction is complete and the official commissioning process to bring its Panda High Plains Hemp Gin™ (the “Panda Hemp Gin”) project online began in early Q4. The commissioning process marks the final stage before beginning commercial operations in Q1 2024 at the 500,000 square foot Wichita Falls, Texas facility. The Panda Hemp Gin will process 10 metric tons of industrial hemp per hour to produce textile-grade fiber, hurd, short-fiber hurd mix, and a nutrient-rich co-product that will be pelletized. The facility is expected to be the largest hemp decortication center in the Western Hemisphere and among the largest in the world.

Using only renewable energy sources, the engineering and production process at the Panda Hemp Gin has been certified green by Mid-South Engineering Company, in accordance with the International Capital Market Association’s Green Bond Principles. Panda Biotech has also partnered with Oritain, a scientific traceability company, to bring the most traceable hemp grown 100 percent in the United States to market.

Additionally, Panda Biotech is actively signing contracts with producers to grow the hemp feedstock for the 2024 growing season, as well as purchasing hemp fiber that has already been harvested or processed. The company recently unveiled an unmatched pay-to-grow program for producers to begin growing Panda hemp. With up-front, guaranteed money and agronomy support, Panda producers also receive tested and proven seed at no cost, successfully mitigating the risk producers may assume and underscoring Panda’s commitment and promise to the farming community. The benefits of growing hemp are substantial, as it is an excellent rotational crop that remediates the soil and provides a competitive margin.

“Each piece of the Panda Hemp Gin production line, including the three miles of overhead pneumatic duct lines, refining, blending, mechanical cottonization, hurd bagging and storage, baling, and more, must be individually started, checked, balanced, and commissioned,” says Panda Biotech Executive Vice President Scott Evans. “Currently, all equipment is individually being brought online to be officially placed in service.”

CARBIOS, a pioneer in the development and industrialization of biological technologies to reinvent the life cycle of plastic and textiles, has received an initial payment of €1.2 million from the French Agency for Ecological Transition (ADEME) for the OPTI-ZYME research project, carried out in partnership with INRAE2, INSA3 and CNRS4 via the TWB5 joint service and TBI6 research units, a project co-funded by the French State as part of France 2030 operated by ADEME. With CARBIOS' aim to optimize and continuously improve its unique enzymatic PET depolymerization technology, the 4-year7 OPTI-ZYME project aims to investigate the scientific and technical levers for improving the competitiveness of the process, optimizing the necessary investments and reducing its environmental footprint.

This collaborative R&D program focuses on the technical and economic optimization of process stages, while preserving the quality of the monomers obtained. These optimizations, new developments and the exploration of innovative solutions should enhance the technology's flexibility with regards to incoming waste. Raw materials could come from different sources that are currently rarely or not recycled, notably food trays and textiles, or a mix of incoming materials. It also aims to limit input and water consumption, as well as regenerate or reduce co-products and ultimate residual waste. Finally, it seeks to support enzyme optimization to maximize the process’ economic profitability and competitiveness.

The project therefore aims to achieve an overall improvement in performance, combining efficiency, quality and environmental sustainability, to benefit the Longlaville plant which is currently under construction, and future licensed plants.

In May 2023, CARBIOS, the project leader and coordinator, announced that it had been awarded a total of €11.4M in funding by the French State as part of France 2030, operated by ADEME, including €8.2M directly for CARBIOS (€3.2M in grants and €5M in repayable advances) and €3.2M for its academic partners INRAE, INSA and CNRS (via the TWB mixed service and TBI research units). This funding, which is made up of grants and repayable advances, will be paid out in several instalments over the course of the project, including an initial instalment of 15%, equivalent to €1.2 million, received by CARBIOS on 5 December 2023. The first Monitoring Committee with ADEME for the first key stage of the project will be held in February 2024 to validate the granting of the second instalment of funding.

This project 2282D0513-A is funded by the French State as part of France 2030 operated by ADEME.

In cooperation with the Swiss company Haelixa, Oerlikon Manmade Fibers Solutions will, in future, be able to make the entire value chain of a textile end product transparent and hence sustainable. The two development partners are offering a solution for the comprehensive traceability of products, as required by the European Green Deal.

An essential part of the solution is the DNA marker technology developed by Haelixa that enables complete traceability of materials. These markers survive all production process steps, validating that the end product is identifiable. "This innovative technology employs distinct DNA tailored for each project, establishing a unique identity for the material," explains Holly Berger, Marketing Director at Haelixa. "Once the DNA is integrated into the material, it becomes irremovable, impervious to falsification or alteration." Handling is straightforward: the DNA marker is fed into the spinning process with the preparation oil, for example. The preparation system is modified accordingly. Further feeding options are currently being developed.

Smart factory: total transparency with atmos.io
The concept is complemented by atmos.io, Oerlikon's digital platform, which records and evaluates extensive production and process data during the yarn manufacturing process. Atmos.io gives the yarn its digital identity during its time on Oerlikon systems, from the melt to the packaged package. This technology has been used successfully for some time to monitor the production process. With atmos.io, deviations in process parameters and yarn data can be identified and rectified within a very short time, which in turn keeps the yarn quality stable and reduces waste rates.

Combining both technologies enables clear traceability of the yarn produced, even in the downstream process steps. Hence, the yarn's components, qualities, manufacturing conditions, and origin are traced beyond doubt in the finished garment. "The unique DNA carries the 'roots' of the yarn digitally recorded in atmos.io into the everyday life of the end consumer," says Jochen Adler, CTO at Oerlikon Manmade Fibers. The textile end products meet the requirements of the digital product passport required by the EU, which contains the information needed to assess their life cycle assessment and circularity. Initial long-term tests have shown 100% traceability of the yarns in the POY and FDY spinning process. If the yarn manufacturer relies on the atmos.io platform, production systems can be adapted relatively easily to use the DNA markers.
