From the Sector

The “Cellulose Fibres Conference 2024” held in Cologne on 13-14 March demonstrated the innovative power of the cellulose fibre industry. Several projects and scale-ups for textiles, hygiene products, construction and packaging showed the growth and bright future of this industry, supported by the policy framework to reduce single-use plastic products, such as the Single Use Plastics Directive (SUPD) in Europe.

40 international speakers presented the latest market trends in their industry and illustrated the innovation potential of cellulose fibres. Leading experts introduced new technologies for the recycling of cellulose-rich raw materials and gave insights into circular economy practices in the fields of textiles, hygiene, construction and packaging. All presentations were followed by exciting panel discussions with active audience participation including numerous questions and comments from the audience in Cologne and online. Once again, the Cellulose Fibres Conference proved to be an excellent networking opportunity to the 214 participants and 23 exhibitors from 27 countries. The annual conference is a unique meeting point for the global cellulose fibre industry.  

For the fourth time, nova-Institute has awarded the “Cellulose Fibre Innovation of the Year” Award at the Cellulose Fibres Conference. The Innovation Award recognises applications and innovations that will lead the way in the industry’s transition to sustainable fibres. Close race between the nominees – “The Straw Flexi-Dress” by DITF & VRETENA (Germany), cellulose textile fibre from unbleached straw pulp, is the winning cellulose fibre innovation 2024, followed by HONEXT (Spain) with the “HONEXT® Board FR-B (B-s1, d0)” from fibre waste from the paper industry, while TreeToTextile (Sweden) with their “New Generation of Bio-based and Resource-efficient Fibre” won third place.

Prior to the event, the conference advisory board had nominated six remarkable innovations for the award. The nominees were neck and neck, when the winners were elected in a live vote by the audience on the first day of the conference.

First place
DITF & VRETENA (Germany): The Straw Flexi-Dress – Design Meets Sustainability
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.

Second place
Honext Material (Spain): HONEXT® Board FR-B (B-s1, d0) – Flame-retardant Board made From Upcycled Fibre Waste From the Paper Industry
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, the product is verified in the Product Environmental Footprint.

Third Place
TreeToTextile (Sweden): A New Generation of Bio-based and Resource-efficient Fibre
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.

The next conference will be held on 12-13 March 2025.

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.

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.

Suedwolle Group introduces ACTIVEYARN®, the company’s first seasonless corporate collection: ACTIVEYARN® is composed of a selection of weaving, flat and circular knitting, hosiery and technical yarns, with advanced spinning technologies, wool blends and other natural and traceable fibres.

While OEKO-TEX® categorizes low-level BPA as less than 100 parts per million (ppm), these new products contain less than 1 ppm BPA, a testament to Freudenberg’s unyielding standards.

DOWN FEEL WA 150LB and FIBERBALL WB 400LB are available globally and more low-level BPA thermal insulation options are available in Asia.

Radilon® Chill-fit is the new solution to maximise the breathability and freshness that a fabric can offer. The highly functional nylon yarn is capable of ensuring an intrinsic and permanent thermoregulation without the need for additional treatments while offering high protection against UV rays. Visitors will be able to touch and feel the yarn for the first time at the autumn edition of Performance Days, the reference trade fair for trends and innovations in yarn, fabric and accessories, to be held in Munich (Germany) on 4 and 5 October.

Radilon® Chill-fit’s high breathability allows air and moisture to pass through quickly, keeping the wearer fresh and comfortable: a result also proven by a specific test on body temperature changes (thermocamera test) comparing a garment made with traditional yarn and one made with Chill-fit.

To reach its goal of being the world’s leading supplier of enhanced recycled polyethylene terephthalate (PET), gr3n is signing a binding Memorandum of Understanding (MOU) with its shareholder Intecsa Industrial to set up a Joint Venture.

gr3n together with Intecsa Industrial will join forces and build a “First-of-a-Kind” manufacturing facility able to produce 40.000 tons of virgin-like PET, commencing EPC phase in Q4-2024 and aiming to be operational in 2027. gr3n’s chemical recycling technology is capable of processing PET from various industries including textile waste, closing the loop for hard-to-recycle PET applications.

The world’s first industrial-scale MADE PET recycling plant will have the capability to process post-industrial and post-consumer PET waste including hard-to-recycle waste, to produce approximately 40.000 tons of virgin PET chips from the recycled monomers saving nearly 2 million tons of CO2 during its operating life. The post-consumer and/or post-industrial polyesters will be both from bottles (colored, colorless, transparent, opaque) and textiles (100% polyester but also mixtures of other materials like PU, cotton, polyether, polyurea, etc. with up to 30% of presence in the raw textile).

The technical concept of the MADE plant is to break down PET into its main components (monomers) so they can potentially be re-polymerized endlessly to provide brand new virgin PET or any other polymer using one of the monomers. Polymers obtained can be used to produce new bottles/trays and/or new garments, essentially completely displacing feedstock material from fossil fuels, as the recycled product has the same functionality as that derived traditionally. This means that gr3n can potentially achieve bottle-to-textile, textile-to-textile, or even textile-to-bottle recycling, moving from a linear to a circular system.

gr3n’s process has the potential to change the way PET is recycled worldwide, enabling huge benefits for both the recycling industry and the entire polyester value chain. Many efforts have been made in the past to transfer enhanced recycling from research laboratories to the manufacturing industry, but the economics and skepticism of the first adopters have constantly blocked the progress of the proposed solutions. Thanks to the MADE technology developed by gr3n, this approach is now feasible and makes gr3n one of the few companies with the potential to provide a reliable enhanced recycling solution that closes the life cycle of PET, and also offers food grade polymer material, processes a large variety of waste and reduces the carbon footprint of these materials usually destined for incineration or landfill.

RadiciGroup took part in the Phygital Sustainability Expo, this year in its fourth edition, which was held in Rome on 5 and 6 July. This event is entirely dedicated to the ecological transition of fashion and design brands through technological innovation. The show is an important platform for discussion on sustainable transition issues, involving Italian and international brands, fashion tech start-ups, representatives from the institutional, business and educational fields, and consumers.

RadiciGroup's participation in the event was further evidence of the Group's commitment to making a contribution to sustainability and circularity in the fashion and textile industry, in collaboration with all the other players in the supply chain. During the narrated fashion show, held on the evening of Wednesday, 5 July, in the evocative archaeological complex of the Imperial Forum Museum, RadiciGroup presented a maxi dress made of Biofeel® eleven, a yarn of completely natural origin featuring high technical, aesthetic and environmental performance. This yarn is produced starting from a small bean cultivated in India on semi-arid land and thus does not compete with human food production. These beans yield a special oil ideal for obtaining biopolymers, such as the one produced by Arkema and spun into yarn at RadiciGroup in Italy.

The dress is not only made from a low environmental impact raw material, but is also an example of ecodesign: the garment was realized on a Shima Seiki WholeGarment knitting machine, where the entire item was knit directly from spools of Biofeel® eleven yarn, bypassing the traditional stages of weaving and tailoring. It is a zero-waste process, as only the quantity of yarn strictly needed for the garment is used.

Biofeel® eleven yarn endows the dress with unique characteristics, including low moisture absorption, greater lightness and high resistance and durability. Besides being 100% biobased, the yarn is also 100% recyclable because it is made of a mono-material polymer, which facilitates its end-of-life recycling and processing into new materials suitable for any application requiring high performance.

As a global provider of sustainable woodfibre products, Sappi will be showcasing its solutions for the garment industry under the theme “Fashion meets Forest” at ITMA 2023 – with sublimation papers and its dissolving wood pulp, used for the production of garment fibres under the “Verve” brand name.

How can the woodfibre industry support a more sustainable garments market? Sappi is eager to answer this question at the ITMA and has created a “knowledge trail” for visitors to explore under the motto “Fashion meets Forest”. Visitors to the stand can follow the journey from wood via cellulose and fibre to the finished yarn and the printed garment.
