From the Sector

Freudenberg Performance Materials Apparel Europe (Freudenberg) has reached a further sustainability milestone: The new Freudenberg Apparel Competence Center in Sant’Omero, Italy, successfully completed the 4sustainability® Chemical Management protocol (4s CHEM) recently and reached the Advanced Level. The aim of the protocol is to progressively eliminate toxic and hazardous chemicals and related risks throughout the production process.

Competence center for interlinings
Freudenberg opened its Apparel Competence Center in Sant’Omero in May 2023. The factory in Italy is an innovative competence center that coats and finishes nonwoven, woven and weft interlinings for apparel customers in Europe.
Freudenberg has now taken the next logical step: as part of a comprehensive audit, the Apparel Competence Center has implemented ZDHC guidelines in its production process. To achieve this, Freudenberg called in the experts from Process Factory, a consultancy that specializes in sustainability topics. With their support, Freudenberg’s Sant’Omero site has reached the Advanced level of the 4sustainability® Chemical Management protocol (4s CHEM), in line with the ZDHC Roadmap to Zero Program.
Implementation is controlled annually based on this protocol and offers companies in the fashion industry a degree of reliability. It guarantees structured, fully transparent procedures, regular monitoring, and continuous control of Freudenberg’s production processes.  

ZDHC
By demonstrating its rejection of environmentally harmful chemicals and substances, the Apparel Competence Center shows that Freudenberg gives top priority to taking responsibility for people and the environment.
The aim of the Zero Discharge of Hazardous Chemicals (ZDHC) Foundation and its globally recognized Roadmap to Zero Program is to eliminate the release of toxic chemicals in the textile and fashion industry’s supply chain based on the ZDHC Manufacturing Restricted Substances List (ZDHC MRSL).
By applying the 4s CHEM protocol, the production site in Sant’Omero is sending a clear signal to the fashion industry that Freudenberg products meet the highest quality standards and are also safe and environmentally friendly.

Bemberg™, a brand of cupro fibre by Asahi Kasei Corporation, Japan, announces its collaboration with luxury couture label Anita Dongre to unveil the ‘Azure’ collection.

Anita Dongre, known for her timeless elegance and commitment to sustainability, has integrated Bemberg™ yarn into the ‘Azure’ collection, symbolizing a dedication to responsible fashion practices. Bemberg™ yarn, sourced from Asahi Kasei in Japan, embodies luxury and environmental responsibility.

The ‘Azure’ collection captures the serene essence of the sea, evoking the tranquil ebb and flow of waves against a backdrop of pristine skies. With soft hues and delicate color palettes, the collection introduces a fresh, breezy aesthetic, featuring flowy dresses, kaftans, and elegant sets designed to elevate the simplicity of spring-summer fashion.

With the aim to help the denim industry reduce the environmental impact of its wastewater and move towards circularity, Archroma, G-Star RAW and Advance Denim have renewed their joint commitment to the production of aniline-free denim apparel based on Archroma’s DENISOL® PURE INDIGO 30.

Their joint aim is to produce high-quality denim in authentic blue shades without the aniline impurity carried through from the synthesis of standard synthetic indigo. In traditional denim production, this aniline remains bound with the indigo pigment on the fabric; the remaining aniline is discharged during the dyeing and washing process. This can be a problem because aniline is toxic to aquatic life and two-thirds of aniline waste currently ends up in wastewater discharge where it could potentially pollute waterways and the ocean.

Archroma developed DENISOL® PURE INDIGO 30 to answer this key challenge. A 30% pre-reduced indigo solution, DENISOL® PURE INDIGO 30 makes it possible to produce indigo-dyed denim without aniline impurities throughout the process.

Easy to use with automated dosing, DENISOL® PURE INDIGO 30 reduces the water needed for preparation, washing and wastewater treatment compared to indigo grains. It also reduces hazardous chemical consumption while allowing high reproducibility and creating the authentic and iconic deep indigo shades traditionally associated with denim.

G-Star RAW is working towards making 20% of its entire collection from Cradle to Cradle Certified® fabrics by 2025. Its partnership with Archroma and Advance Denim contributes to this goal, since the aniline-free DENISOL® holds a Gold Level Material Health Certificate from the Cradle to Cradle Products Innovation Institute. DENISOL® PURE INDIGO 30 is also compliant with other eco-standards and the requirements of leading retailers and brands.

Advance Denim, G-Star RAW and Archroma have previously collaborated to launch collections based on Archroma’s EarthColors® technology, which upcycles plant waste from the herbal industry to create sustainable colorways.

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.

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.
