From the Sector

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.

C.L.A.S.S. MATERIAL HUB is a careful selection of smart ingredients made by cutting-edge companies and innovators across the globe. The wide range includes transparent and traceable products, which can be natural/organic, up or re-cycled/able, or innovative and always representing a new generation of innovation that is minimizing its impact on people, environment, animals and oceans.

Sensil® BioCare sustainable premium Nylon fiber is enhanced with a technology, that helps lessen the persistence of textile waste in sea water and in landfills. With its embedded technology, if any microfibers of Sensil® BioCare garments are released during washing, they will be broken down at a quicker rate compared to conventional Nylon 6.6 fibers when they end up in the oceans. Tests were conducted in both landfill soil and sea water simulations to understand the potential impact of Sensil® BioCare on both ecosystems. Specifically, initial testing following the ASTM D6691 Standard Test Method For Determining Aerobic Biodegradation Of Plastic Materials In The Marine Environment and the ASTM D5511 Standard Test Method For Determining Anaerobic Biodegradation Of Plastic Materials Under High-Solids Anaerobic-Digestion Conditions indicates that Sensil® BioCare yarns break down more rapidly (with a biodegradation of about 40% in 500 days) than conventional nylon. These promising findings point to reduced waste accumulation in both oceans and landfills.

NILIT, owner of the sustainable brand SENSIL®, has also teamed up with The Ocean Foundation’s Blue Resilience Initiative to reestablish and safeguard essential ocean meadows and other coastal habitats. These marine grasslands, which are being damaged at a rate of two football fields every hour, are vital ecosystems for sequestering CO2 from the atmosphere, thus reducing global warming and ocean acidification. In addition, ocean grasslands sustain sea life, defend coast lines against erosion and storm surge, and support economies around the world.

NILIT’s plant in Israel, who produce Sensil ® Biocare boosts, renowned certifications such as GRS (Global Recycled Standard)*, ISO 9001**, ISO 14001*** and ISO 45001****. Moreover, the company has already announced that all other plants in  the USA, China and Brazil will be ISO 14001 certified within 2021 and ISO 45001 certified within 2025. Worth to mention, 40% of Nilit’s team is made up of women.

• Huntsman Textile effects redefines dyeing of polyester including microfiber and blends with UNIVADINE® E3-3D diffusion accelerant
• Eco-friendly diffusion accelerant provides reproducible, high-speed polyester dyeing

Singapore – Huntsman Textile Effects introduces UNIVADINE® E3-3D next-generation diffusion accelerant to help mills achieve high-performance dyeing of polyester, microfibers and blends in an environment-friendly way that complies with current and anticipated industry sustainability standards.

The demand for polyester and man-made fibers is booming as sports and athleisure apparel markets expand rapidly around the world. At the same time, big-name brands that set trends in the sector continue to increase focus on sustainability and performance. As such, this is putting pressure on mills since the current industry standard involves chemically active diffusion accelerants that contain unwanted chemicals and require additional leveling agents and anti-foaming products that may be hazardous to people and the environment.

Developed by Huntsman Textile Effects specifically to meet these challenges, UNIVADINE® E3-3D diffusion accelerant is low-odor, free of benzyl benzoate and other hazardous substances. Part of Huntsman’s range of innovative dyEvolution™ dyeing auxiliaries, it uses Huntsman’s Active Diffusion Technology to enable high-speed dyeing with best-in-class leveling, retarding and migration properties.

“UNIVADINE® E3-3D diffusion accelerant delivers across three key dimensions – diffusion, leveling and migration – for exceptional performance and environmental and economic sustainability. Its environmental credentials offer mills greater processing flexibility and an optimum price-performance ratio,” said Kerim Oner, Global Marketing Manager for Dyeing Auxiliaries at Huntsman Textile Effects. “We expect this latest offering to change the way that the industry dyes polyester and blends while meeting stringent environmental standards.”

UNIVADINE® E3-3D diffusion accelerant has a high affinity to polyester, causing the fiber to swell and increasing the diffusion of the disperse dye, even at lower temperatures. Multiple leveling mechanisms then slow down the exhaustion rate to ensure safe, defect-free dyeing. Finally, as the dye bath heats up, the product’s strong support for disperse dye migration ensures the dye molecules are evenly absorbed.

As a result of this cutting-edge diffusion technology, UNIVADINE® E3-3D diffusion accelerant can be used to successfully dye polyester fibers in tightly wound or high-density yarn/beam dyeing and is suitable for jet applications without the need for anti-foaming products. Reducing exposure to high heat, its Active Diffusion Technology minimizes the potential to damage the elastane in polyester-elastane blends and provides for on-tone dyeing of microfibers. The superior migration support of UNIVADINE® E3-3D diffusion accelerant also increases reproducibility, allowing mills to dispense with additional leveling agents. Polyester, microfibers and blends treated with UNIVADINE® E3-3D diffusion accelerant comply with the requirements of bluesign®, in addition to being suitable for Standard 100 by OEKO-TEX® and an approved input dyeing auxiliary chemical for GOTS (Global Organic Textile Standard) certified textile products*.
