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.

Freudenberg Performance Materials Apparel (Freudenberg) launches its biodegradable fusible cotton shirt interlinings range 46xx. With this innovation, the world’s leading specialist in woven, knitted, weft and nonwoven interlinings reduces its impact on the environment and supports customers in achieving their own sustainability objectives. In Asia, the series is marketed under the name 42xx series.

Approved biodegradability and non-toxicity by Hohenstein Laboratories
The new Freudenberg fusible interlinings for shirts and blouses have been developed in such a way that they are harmless to people and the environment at the end of their life cycle. Germany’s independent Hohenstein Laboratories performed biodegradation tests on the 46xx series, based on the Hohenstein method which draws on DIN EN ISO 11721-2:2003 and EN ISO 846, and approved it as biodegradable and ecotoxicologically harmless. The tests by Hohenstein showed no negative effects on either the germination of garden cress nor on earthworms in the acute toxicity test.

Energy-saving interlining
The new biodegradable shirt interlinings also show great potential for energy saving, as the fusing can be performed at a low temperature. Concretely, this means that the resulting temperature between the upper fabric and the shirt interlining during fusing is only 127°C which is significantly lower than the commonly used temperature of 143°C. Certified to OEKO-TEX® STANDARD 100 Class II for successfully testing for no harmful substances, the shirt interlinings are washable at up to 40°C and resistant to dry cleaning. In addition, it has also passed all ecological-toxicological tests and is a perfect end-of-life cycle solution.

Product details and availability
The products in range 46xx are available in Europe in the color white and the following weight classes: 4605 (90g/m2), 4616 (150g/m2) and 4618 (55g/m2). The adhesive of the interlinings consists of a 100% degradable bio-polymer. The shirt interlinings are ideal for reinforcing shirt and blouse collars, cuffs and plackets used in fashion, leisure and business clothing. The biodegradable, non-toxic interlinings are particularly important for labels with an ecologically sustainable claim.

• Spunbond, meltblown and composite structures for new market opportunities

RadiciGroup is participating with its Advanced Textile Solutions business area at Index in Geneva from 18 to 21 April 2023. Among the Group’s products showcased are spunbond and meltblown for different application sectors, such as roofing, construction, automotive, HO.RE.CA. and filtration.

“The key message we are bringing to the fair is sustainability,” noted Enrico Buriani, CEO of the Nonwovens division of RadiciGroup Advanced Textile Solutions. “Those who already know us know that, for many years, the Group has been focused on proposing low environmental impact products and processes where sustainability is scientifically measured or certified by independent third parties. Our company is dedicated to nonwovens, which, by the way, are produced using 100% renewable energy. We have expanded our portfolio of innovative solutions for customers interested in realizing projects with sustainability as an essential requirement.”

Respunsible® is a spunbond brand manufactured from recycled polypropylene. A preliminary Life Cycle Assessment (LCA) study was carried out by RadiciGroup to demonstrate the correlation between the reduction in environmental impact and the percentage increase in recycled material. The final results demonstrate that a variable percentage of from 50 to 70% recycled material leads to a reduction in CO2 emissions of from 30 to 40%, compared to a fabric made of 100% virgin material, without comprising high technical performance.

Additionally, since RadiciGroup has achieved ISCC PLUS certification (International Sustainability and Carbon Certification), it can offer bio, biocircular or circular polypropylene spunbond and meltblown nonwovens, in which the sustainable polypropylene is biomass balanced. This certification signifies traceability along the supply chain and verifies that the certified companies meet high environmental and social standards.

“Since 2020, we have had a technologically advanced meltblown production line,” Mr. Buriani concluded. “This allows us to make composite structures, sold under the brand name Radimelt®. Now our goal is to expand our filtration applications, diversifying and developing new business, for instance vacuum cleaner bags or HVAC (heating, ventilation and air conditioning) system filters, where we can meet the high efficiency and mechanical resistance demanded, thanks to our latest generation technology.”

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.”

The Global Organic Textile Standard is pleased to announce the release of GOTS Version 7.0, which features an expanded scope of environmental and social criteria while maintaining a standard that is practicable for industrial production and appropriate for a wide range of products. During the regular year-long revision process, international stakeholders with expertise in organic production, textile processing, textile chemistry, human rights and social criteria, as well as representatives from industry, NGOs and civil society organisations, contributed to the new Version 7.0 through multiple consultation rounds. Final decisions were made by the multistakeholder GOTS Standard Revision Committee.

GOTS Version 7.0 provides a comprehensive solution for companies who want to produce organic textiles ensuring compliance with environmental and human rights due diligence along the entire supply chain, from field to finished product. With full traceability from origin to destination, GOTS certification provides an efficient means of verifying genuine sustainability efforts. GOTS 7.0 introduces new requirements to conduct risk-based due diligence of Certified Entities’ own operations and their supply chains based on the UN Guiding Principles for Business and Human Rights and the OECD guidelines. The Social Criteria section was substantially revised to include a broader human rights-focused approach. GOTS 7.0 now allows recycled organic fibres as additional materials. Key requirements, such as certified organic fibre content, a general ban on toxic and harmful chemicals such as PFAS, conventional cotton and virgin polyester restrictions, and social compliance management, are maintained in GOTS Version 7.0.

Some of the changes in Version 7.0 include:

• GOTS and the Manual for the Implementation of GOTS were restructured, and sections were grouped to reflect the standard’s scope.
• New due diligence criteria ensures that Certified Entities address their actual and potential negative impacts on human rights and the environment.
• GOTS Environmental Criteria, Product Stewardship, and Environmental Health and Safety (EHS) requirements will also apply to the subcontractors of chemical formulators.
• Criteria for the incoming organic material have been made stricter.
• Quinoline is included among the prohibited substances and some existing restrictions have been made tighter such as of “aniline, free”, residue limit is decreased to 20 mg/kg from 100 mk/kg.
• GOTS 7.0 reduces the permissible quantity of recycled synthetic (polymer) fibres in its certified products, taking into account the disadvantages associated with recycled synthetics, such as microplastics and poor quality.
• In the pursuit of circularity, GOTS will allow use of recycled GOTS Goods waste as an additional fibre in its certified products.
• GOTS Human Rights and Social Criteria will now require Certified Entities to respect internationally recognised human rights protocols, including the International Bill of Human Rights and other international human rights treaties.
• Criteria concerning Discrimination, Violence and Harassment were revised to make them more comprehensive and include the International Labour Organisation (ILO) Violence and Harassment Convention (C190).
• Certified Entities are now required to develop a plan to cover the living wage gap.
• GOTS Occupational Health and Safety criteria were revised to consider best international practices and recommendations from the ILO.

• Standard assesses fibre release, biodegradation and ecotoxicity for the first time

Testing service provider Hohenstein has worked with the project partners Trigema, Freudenberg, DBL ITEX and Paradies to create a new standardized test method for detecting and classifying the environmental effects of textiles during washing. DIN SPEC 4872 combines analysis of fibre release, biodegradability and ecotoxicity. The test method according to DIN SPEC 4872 shows how many fibres are released during textile laundering, how well these fibres degrade in wastewater and how harmful the fibre residues are to the environment.

Studies have shown that washing textiles releases microfibres into the wash water, which cannot be sufficiently retained by wastewater treatment plants. Synthetic fibres pose the greatest risk to the environment because of their longevity and inability to biodegrade. However, Hohenstein project manager Juliane Alberts does not give the all-clear for biodegradable fibres and natural fibres: "Biodegradability alone does not mean that pure natural fibres, for example, are completely harmless to the environment. They, too, remain in ecosystems until they completely degrade and can also have a negative impact. In addition, additives, auxiliaries or finishes used in textile production can further slow the degradation process and leach into the environment."

The new standard enables textile producers and suppliers to test, evaluate and compare products for fibre release during washing and environmental impact. Juliane Alberts sees this systematic evaluation as an opportunity for the textile industry to take the initiative on environmental impact: "Our reliable data can be used as a basis for more targeted product development. This is a way to actively and consciously control further environmental pollution."

From April 2023, OEKO-TEX® will officially launch its new ORGANIC COTTON label. Two initial pilot customers have already been certified by the testing service provider Hohenstein: the Indian textile supplier Milan Group and the Turkish cotton producer Akasya.

The new organic label ensures that all requirements for labeling as organic cotton are met. In addition to testing in accordance with OEKO-TEX® STANDARD 100, it ensures that the cotton contains less than ten percent genetically modified material, complies with pesticide limits and guarantees its organic origin.

Textile companies whose products have been certified with the OEKO-TEX® STANDARD 100 can now have their certificates extended to an ORGANIC COTTON certificate after ensuring ecological production.

"A combination with OEKO-TEX® MADE IN GREEN is ideal," explains Ivonne Schramm, Head of OEKO-TEX® at Hohenstein. "This ensures environmental friendliness, transparency and socially responsible conditions in a single certification."

The certificate can be used for ready-made articles (e.g. T-shirt, bedspread, etc.) as well as for textile intermediate products (e.g. intermediate products such as raw fibers, yarns, etc.). Mixtures of organic and conventional cultivation are not permitted.

By using a high share of recycled content in its Evolon® materials, Freudenberg Performance Materials (Freudenberg) offers technical packaging textiles with a carbon footprint decreased by 35%. An independent LCA study showed additional benefits such as energy resource savings and lower water use. Furthermore, Evolon® fabrics provide sustainability benefits over the packaging entire life cycle thanks to high end performance and durability.

By replacing virgin PET with recycled PET, the cradle-to-gate carbon footprint of Evolon® packaging textile materials decreased by 35%. This is the result of a study by an independent LCA and eco-design consultancy firm, which made a Cradle-to-Gate assessment of several Evolon® products using virgin PET or recycled PET. The study was finalized in 2022 and conducted according to the principles of ISO 14040/ ISO 14044 standards, following the recommendations of the Product Environmental Footprint and the Circular Footprint Formula.

Evolon® microfilament textiles have a small carbon footprint because their manufacturing process uses low CO2 energy sources. The fabrics are lightweight and can be reused throughout entire production programs, e.g. of a car model when it is about the automotive industry. Furthermore, the new Evolon® RE fabrics contain up to 85% of recycled PET which is produced in-house out of post-consumer PET bottles.

Evolon® textiles are suitable for reusable technical packaging, which eliminate the use of thousands of disposable packaging materials. Evolon® fabrics offer scratch-free, lint-free, high-end surface protection for molded plastic parts, painted parts and other sensitive industrial and automotive parts during transport. This contributes to lower the scrap rate of parts and provide both financial and ecological benefits. By using Evolon® reusable packaging to transport highly-sensitive parts, customers can increase their efficiency and save resources.

January, 3rd, ZDHC announced the release of the updated ZDHC Man-Made Cellulosic Fibres (MMCF) Guidelines Version 2.0, and its supporting document. By publishing these documents the industry shall be pushed forward increasingly innovative and sustainable fibre production.

The ZDHC MMCF Guidelines V2.0 now include the Responsible Fibre Production Guidelines, Wastewater Guidelines and Air Emissions Guidelines as three separate chapters in a single document.

Fibres are key components of production processes in the textile and fashion value chain and it is crucial to reduce the environmental impact of their manufacture. ZDHC guidelines give suppliers producing MMCF unified criteria for measuring output indicators like wastewater, sludge, air emissions and other process-related parameters.

Among other changes, this update reflects the expansion of the scope to accommodate Viscose Filament Yarn, Lyocell, Cuprammonium Rayon (Cupro) and Cellulose Acetate (Acetate). The ZDHC Man-Made Cellulosic Fibres (MMCF) Guidelines V2.0 provide an aligned approach for included fibres, including defined chemical recovery, wastewater and sludge discharge, and air emission discharge.

ZDHC continues to advocate for the improvement of processes which minimise emissions while also working towards the recovery of input substances and by-products. These dual goals, reduction and recovery, directly address the negative impact of outputs arising from MMCF production.

ZDHC MMCF Guidelines Industry Standard Implementation Approach Version 2.0: Additional Industry Support for Implementation
Along with the ZDHC Man-Made Cellulosic Fibres (MMCF) Guidelines V2.0, ZDHC has also updated its ZDHC MMCF Guidelines Industry Standard Implementation Approach. This document aims to support the implementation process of the ZDHC MMCF Guidelines V2.0, and features new implementation timelines that assist suppliers in setting their goals to achieve Foundational, Progressive or Aspirational Level on the ZDHC Supplier Platform.
