Aus der Branche

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.

California born and bred, Tillys is one of fashion’s leading specialty casualwear retailers. And now, thanks to its collaboration with Recover™ , their premium denim brand RSQ, it is set to become a leader of sustainable fashion.

The three brands – Tillys, Recover™ and RSQ – have come together to create a sustainable capsule collection. The new collection includes classic-inspired denim, a tee, and an on-trend chore jacket, all of which contain a minimum of 20% of Recover’s low-impact recycled cotton fiber. To shop the exclusive Recover™ pieces in the RSQ collection, go to tillys.com or visit one of Tillys stores across 33 states.

To bring this collaboration to life, textile waste has been salvaged that would otherwise end up in a landfill to create high-quality recycled fiber that Tillys used to produce its premium-quality RSQ collection. Using recycled fiber significantly reduces the carbon and water footprint compared to apparel made with virgin fiber. This collaboration models how post-industrial textile waste can be integrated back into the system creating a more sustainable production model.

“We are delighted to celebrate this new partnership with Tillys, helping to reduce the environmental impacts created by the fashion industry and pave the way towards a more sustainable future.”

• Carbios has succeeded in producing a 100% enzymatically recycled white PET fiber from colored textile waste
• At the same time, the company has produced the first 100% recycled PET bottles, that have successfully passed the food contact validation tests, from the same textile waste.
• Carbios received €827,200 for the validation of this final technical stage of the project co-funded by ADEME

Carbios announced the validation of the 3^rd and final technical step of the CE-PET research project, co-funded by ADEME3 (France’s Environment and Energy Management Agency), for which Carbios is the lead partner alongside its academic partner TWB. This achievement confirms, once again, the full potential and breadth of Carbios’ enzymatic recycling process, C-ZYME™. This breakthrough innovation makes it possible to produce a wide variety of products of equivalent quality to those of petro-sourced origin from any PET waste, including textiles.
 
The first white PET fiber recycled enzymatically from colored textile waste
Worldwide, around 90 million tons of PET are produced each year, more than 2/3 of which are used to manufacture fibers. However, only 13% of textile waste is currently recycled, mainly for downcycling, i.e. for lower quality applications (such as padding, insulators or rags). By successfully manufacturing at pilot scale a white PET fiber that is 100% enzymatically recycled from colored textile waste, Carbios is paving the way for the circular economy in the textile industry.  C-ZYME™ is now on the doorstep of industrialization and will soon enable the biggest brands to move closer to their sustainability goals.
 
Emmanuel Ladent, Chief Executive Officer of Carbios: « Thanks to our breakthrough process, it will soon be possible to manufacture, on a large scale, t-shirts or bottles using polyester textile waste as raw material. This is a major breakthrough that gives value to waste that currently has little or no value. It is a concrete solution that opens up a global market of 60 million tons per year of potential raw materials and will help to reduce the use of fossil resources. »
 
Separate collection of textile waste soon to be mandatory in Europe
From 1 January 2025 the separate collection of textile waste, which is already in place in some countries, will be mandatory for all EU Member States (European Directive 2018/851 on waste).  Carbios’ process will enable this waste to be sustainably recovered and included in a true circular economy model.
 
These technological validations were carried out as part of the CE-PET research project, co-funded by ADEME3. In particular, the project aimed to develop Carbios’ enzymatic PET recycling process on textile waste. The C-ZYME™ technology is complementary to thermomechanical recycling and will make it possible to process plastic and textile waste deposits that are currently not or poorly recovered. For the validation of this stage of the project, Carbios received €827,200 (€206,800 in grants and €620,400 in repayable advances).

The textile industry is constantly searching for new, sustainable, and circular materials. Following thorough research and testing, Spinnova and KT Trading have developed a natural leather fabric made from leather waste without harmful chemicals.

"Leather is an amazing high-quality material with unique properties. With this new textile, we have taken yet another step towards completing the circular economy for leather," says Kristian Geert Jensen, CEO of KT Trading, who now has a joint venture with Spinnova.

Spinnova CEO: Sustainable innovation
Together with KT Trading, ECCO’s key leather provider, Spinnova has established the Respin company - a new joint venture. The partners are already constructing a leather fibre production pilot plant in Finland.

ECCO’s Applied Research division and Spinnova have been in a R&D collaboration since 2018 and have made successful trials with spinning the protein biomass into fibre. Processing leather raw material does not require further technology development from Spinnova. The company already has proof of concept from using the method on wood-based raw material.
