ITA Aachen - Digital ring spinning tester for recycled fibres enables spinning of fine yarns with high recycled fibres content
The Institut für Textiltechnik of RWTH Aachen University (ITA) will be exhibiting a digital ring spinning tester, which spins recycled fibres directly and conventionally with a particularly high content of 60-70 percent. Up to now, recycled yarns have mainly been rotor-spun in this blend ratio. This results in rather coarse yarns and is not suitable for finer textiles such as outerwear. Ring spinning of recycled yarns now enables the spinning of finer yarns and thus a higher application level for recycled materials.

A unique selling point of the ITA ring spinning tester is the simultaneous spinning in the direct spinning process from the sliver and in the classic ring spinning process. For this purpose, the strength and elongation of the spun yarn are determined online and digitally for the first time. The real-time measurement allows process parameters and yarn properties to be adjusted iteratively and quickly. The ring spinning tester was upgraded from an existing tester to Industry 4.0 standard and is operated via a tablet. Operation via tablet enables the adjustment of process parameters including online quality monitoring remotely from anywhere in the world.
 
For this purpose, the ring spinning tester is also able to produce fine ring spun yarns. These yarns made from recycled material opens up a multitude of further fields of application for woven and knitted goods. Now, for example, clothing and technical textiles can be made from recycled material, the production of which was not possible before - such as outerwear made from recycled material. The development of new industries and fields of application opens up new market potential for recycled yarns - also and especially for processing in Europe. This creates the opportunity to preserve key technologies and jobs in cost-intensive locations.

ITA Augsburg - Recycling Atelier: Walk4Recycling
The Recycling Atelier of the Institut für Textiltechnik Augsburg gGmbH on stand H3-A207 presents the textile recycling from used textiles into new products via the various process steps and, together with the industrial partners, opens up solution paths for industrial implementation.

Under the headline "Walk4Recycling", a tour of the fair shows the cycle of used textiles from used knitwear into a new knitted pullover via a ring yarn made from a blend of 65 percent recycled cotton and 35 percent virgin polyester. The key innovation here is the high proportion of recycled fibres from post-consumer textiles for a ring yarn of this fineness. Today, mainly coarse rotor yarns for low-quality textiles are spun from these materials. The industrial partners participating in the Walk4Recycling are partners of the Recycling Atelier and contribute with their technologies to the fact that fibre material from old clothes can be processed in various process stages into a yarn of new value and high-quality ready-made garments.

The Walk4Recycling offers visitors the opportunity to experience a complete recycling cycle with the numerous process stages from tearing the old textiles, preparing and spinning the fibres and knitting a new jumper live during the fair. Get detailed information on the mechanical recycling of clothing via QR code, website and flyer about the participating exhibitors and their machines and technologies. A short movie will give you additional insights into the various processes involved in the production of the jumper.

The steering committee for the Denim Deal has announced that Haelixa, the Swiss standard in physical traceability, is approved as a new signature. The Denim Deal is an international collaboration of more than 50 private and public sector companies united in the commitment to produce denim more circularly.

The Denim Deal aims to close the loop and achieve change in the value chain. Based in Amsterdam, the group is working towards a circular economy where textile waste no longer exists. The brand and manufacturing members pledge to work towards using 5% recycled post-consumer cotton in all future denim collections and produce 3 million denim jeans made with 20% recycled post-consumer cotton.

Coordination of the Denim Deal is led by Roosmarie Ruigrok, where the objective is to unite potential allies who have made the journey to circularity a priority. She has been working to improve sustainability in textiles for more than two decades and is an expert on enrolling the correct stakeholders to instigate change. Ruigrok states, "a circular supply chain in the textile industry is like a well-prepared machine - it ensures that every part of the production process runs smoothly, from sourcing post-consumer materials to delivering well-made finished products to customers. It not only drives efficiency and profitability but also builds trust among stakeholders and fosters sustainable practices - we welcome Haelixa who offers a trustful traceability solution."

Over the last few years, the demand for the technology in recycled denim has grown as brands are asked to validate their recycling claims. Haelixa’s unique DNA solution marks and traces fibers from the source to retail. Using DNA to mark the recycled post-consumer cotton, Haelixa substantiates claims by testing the final garment to validate that the marked waste is present.

The Denim Deal is pushing to lead the change in how denim is made. Changing the standards of operation is always challenging, and traceability is a key to authenticating recycled claims. “We are committed to promoting the use of recycled fibers through traceability and thrilled to align with this group,” said Holly Berger, Haelixa’s Marketing Director. “The goals of the Denim Deal support our vision for a circular economy.”

Specifically, Ctrl+Z is material science that hits “undo” on post-industrial waste delivering fabrics made from recycled and regenerated content that look and feel identical to their former compositions with increased strength and durability.

Kelheim Fibres, a leading manufacturer of viscose speciality fibres, has joined Recycling Atelier Augsburg. Recycling Atelier Augsburg is a unique centre for research and development in the field of textile recycling. It is located at the Institut für Textiltechnik Augsburg an affiliated institute of Augsburg University of Applied Sciences. The two institutions founded the Recycling Atelier in June 2022 together with twelve partners from the German textile industry.

In the Recycling Atelier, the focus is on the triad of technical and ecological sense as well as economic benefit. In this way, the partners of the Recycling Atelier are standing up against fast fashion, outsourced corporate responsibility and a general decline in raw material quality, which often fuels downcycling - the low-quality reuse - of materials.

As a model factory, the Recycling Atelier Augsburg combines the most important processes of textile recycling and offers holistic and comprehensive research along the value chain," explains Georg Stegschuster, head of the Recycling Atelier Augsburg. The scientists research on all process steps of textile recycling: from material analysis to sorting, preparation and textile processing to sustainable product design. Comprehensive data collection and the use of artificial intelligence as well as innovative materials play a central role.

Kelheim Fibres is a producer of high-quality viscose fibres, which consist of cellulose, the main component of the renewable raw material wood, and are used worldwide for products in areas such as hygiene, textiles, and technical applications.

"In New Business Development as well as Fibre and Application Development, we follow the Open Innovation concept - the cooperation with the Recycling Atelier offers us an ideal platform for this. Here we work with partners to advance sustainability and performance," explains Maik Thiel, project manager at Kelheim Fibres.

Recycled cotton fibres are often very short or of uneven length, which makes further processing of 100 % recycled material a challenge. Adding speciality fibres from Kelheim Fibres should enable the production of high-quality new products, such as nonwovens. In the future, the fibres provided by Kelheim Fibres will also be made from recycled pulp.

Textile waste is a problem in Europe. Out of 7-7.5 million tonnes of textiles discarded every year, 30-35 % are collected separately – and of that quantity, 15-20 % are sorted by medium and larger sorting facilities within the EU. After sorting, 60 % still qualify as wearable clothes, however after a second or third collection-loop, all of the textiles become non-wearable sooner or later. Therefore, fibre-to-fibre recycling is becoming increasingly important to preserve the valuable resources.
 
The textile recycling value chain is not yet mature, but we are on the verge of a turning point, as different fibre-recycling technologies are deployed on a large scale. If successful, the textile recycling industry could reach a recycling rate of 18 to 26 percent of gross textile waste in 2030. This would create economic, social and environmental value that could total 3.5 to 4.5 billion euros in 2030.

Today, there is a sorting gap to achieve a circular economy for textiles in Europe. To feed this new circular value chain, a significant sorting-capacity increase is needed with 150 to 250 sorting and recycling facilities nearby, as the McKinsey-study “turning waste into value” assessed.

There is also a technology and capacity gap in sorting for reuse and recycling to ensure that high quality raw materials from non-wearable textile waste can be made available on a large scale. This is why the “Transform Textile Waste into Feedstock” project was initiated by TEXAID, within the ReHubs initiative together with well-known stakeholders of the textile value chain.

The major outcome of this project will be a sorting-factory blueprint fulfilling the requirements to the future needs of fibre-to-fibre recycling, enabling the future of more sustainable textiles by using recycled fibres. TEXAID, who is leading the project, is committed to build and operate scalable sorting facilities across Europe, the first with a capacity of 50,000 tonnes by the end of 2024.

Companies like Concordia, CuRe Technology, Decathlon, Inditex, Indorama Ventures, L’Atelier des Matières, Lenzing, Marchi & Fildi, PurFi, Södra, Worn Again and others are taking part in the project to jointly evaluate technologies and the business case for scaled sorting for reuse and recycling. ITA Academy GmbH (in cooperation with RWTH Aachen) together with CETIA has been commissioned for the assessment of technologies. The outcome will be an innovative sorting system 4.0, building on cross-functional technologies with digitalization and automation are at the heart.

Sustainable solutions provider Perstorp has added new corporate sustainability targets, for water and waste, to its sustainability strategy. Its long-term sustainability ambition is to become Finite Material Neutral, which involves water and waste, along with raw materials, energy and catalysts. In 2021 the company set its first 2030 targets, for greenhouse gas emissions (using approved science-based targets) and (eco) toxic impact. Now Perstorp has added new sustainability targets that will address its long-term ambition.

These new 2030 corporate targets (all measured using 2019 as the base year) are:

• 30% absolute reduction of freshwater consumption
• 30% absolute reduction of hazardous waste directed to disposal
• 30% absolute reduction of non-hazardous waste directed to disposal

"Fresh water consumption and waste are two areas of big importance in reducing our environmental impact and working toward increased circularity," says Anna Berggren, Vice President Sustainability at Perstorp Group. "Fresh water scarcity is already a fact around the world, and we have a responsibility to reduce our consumption and utilize alternative water sources. We must also minimize waste generation and find new circular solutions of reusing and recycling the waste streams into new products, either ourselves or so that a third party can use them as raw material. We have set ambitious and absolute sustainability targets, that are to be achieved regardless of production growth. To be able to reach these targets we have several large projects planned that will contribute significantly."

All Perstorp production plants use water for multiple purposes, including, for example: for cooling, as a solvent for chemical reactions, as a carrier for products, and as a heat-transfer medium. One way to reduce fresh water consumption is to purify and recycle wastewater. Perstorp sees this as an important core technology and is planning to invest in wastewater recycling projects at several of its production sites.

A key to reducing waste directed to disposal is to develop circular solutions that use waste streams as raw materials for new products. One example is Project Air, in which captured carbon dioxide together with residue streams from Perstorp's production plant in Stenungsund, Sweden, will serve as raw material for production of sustainable methanol that will replace all the virgin fossil methanol used by Perstorp in Europe.
