Digital Product Passports can now be processed at TEXAID’s largest sorting facility, thanks to circular.fashion’s intelligent sorting stations, which use RFID and NFC technology to improve the quality and consistency of manual sorting.

Digital Product Passports (DPP) have been recognised by the EU as an enabler for circular fashion and textiles. Technology company circular.fashion has been a leader in this effort, releasing the circularity.ID in 2018 and developing Intelligent Sorting Stations to bring ID based sorting to the textile reuse and recycling industry.

ID based sorting optimises the manual sorting process for reuse and recycling by giving sorters data to make decisions more accurately and consistently. TEXAID has, by adopting this technology, increased Europe’s capacity to process DPPs.

The installation and testing of TEXAID’s new Intelligent Sorting Stations was completed successfully shortly before the holiday period. Initial test results indicate that ID based sorting can make sorting decisions more reliable and more consistent. The team also sees a potential for ID based sorting to reduce training costs for new employees and maximise the value of their sorting decisions. This advancement was made through the CIRTEX project, funded through the KMU Innovativ funding programme from the German Federal Ministry of Education and Research.

The Intelligent Sorting Stations at TEXAID are now operational, and brands and retailers have the ability to adopt the circularity.ID as a Digital Product Passport and have textile products returned to TEXAID for ID based sorting.

Monforts has installed and commissioned a new Montex finishing range at the Baltic Works of Halley Stevensons in Dundee, Scotland, to further boost the weatherproofing specialist’s highly flexible operations.

The range, with a working width of two metres, was built at the Montex assembly plant in Austria and consists of a Montex®Coat coating unit in knife execution for paste and foam coating and a Montex 8500 6F stenter.

Founded in 1864, Halley Stevensons has amassed unique technical know-how and manufacturing experience in the art of waxed cotton for weatherproofed fabrics and is able to provide international orders in custom colours and finishes to very low minimum quantities where required. The company exports worldwide and its premium brand customers include Belstaff, Barbours, Filson and J.Crew.

The range has replaced one of the company’s older stenter/coating lines and has already enabled Halley Stevensons to recreate various products with lower coating applications at higher speeds than was previously possible.

Waxed cotton was originally developed by sailors in the early 15th century when Scottish North Sea herring fleets began treating flax sailcloth with fish oils and grease in an attempt to waterproof their sails. Remnants of these sails were used by the sailors as capes to withstand the high winds and sea spray.

By the mid 1850s, sailcloth was being treated with linseed oil, but while initially highly effective, it would yellow and stiffen through weathering over time and eventually lose its waterproofing qualities.

In the years that followed, various treatments were applied to cottons in an attempt to find the most effective weatherproofing solution, and the combination of densely-woven cotton impregnated with a paraffin waxed coating proved most successful. For over 150 years, Halley Stevensons created many different variations of both woven constructions and finishing treatments and now supplies thousands of metres of waxed cotton every year, with each roll produced to custom specifications.

“The beauty of waxed cotton is its durability and longevity,” says Managing Director James Campbell. “The fabrics are breathable, with the wax adjusting to ambient temperatures to be softer and more breathable in warm weather and stiffer and more wind proof in cold conditions.”
While traditional waxes are petroleum or paraffin based, Halley Stevensons has always been comfortable about using a waste product from industry and reusing it to make products that last a lifetime.  

“We are always exploring different finishing techniques and one of our most popular finishes is our hybrid aero – an emulsified blend of waxes,” Campbell says. “This fabric is water repellent but has little wax in the mixture so the handle is much drier to touch than the traditional wet waxes.”

The company has also recently launched a new 100% plant-based wax – Ever Wax Olive – consisting of a blend of olive oil, rape seed and castor bean with comparable water repellence to petroleum and a far better rating than other natural waxes which have come before it.

“The high tradition of skills and fabric innovation imposed by our original guildsmen is still our benchmark standard of honest workmanship today,” Managing Director James Campbell concludes “We use responsibly sourced cotton fabrics and processes that are gentle to the product and low impact to the environment. Our dyeing methods use very low levels of water and our waxes are simply heated up for application and cooled down to store when not in use, meaning no waste discharges. Now, with this new Monforts line, we are also achieving running speeds two-to-three times faster than with the older stenter, combined with less gas usage. It’s proved a great partnership.”

More than 350 million tons of plastic are produced worldwide every year, and vast amounts of plastic waste simply end up in the environment. The circular economy offers enormous potential for keeping plastics in the loop and thus conserving resources and the environment. Since 2018, six Fraunhofer institutes in the Fraunhofer CCPE cluster have been researching how to make the plastics value chain circular, and Prof. Manfred Renner has been the new head of the cluster since August 2022. Research results, implementation projects and strategies to accelerate the transformation to a circular plastics economy will be presented by Fraunhofer CCPE at the first international Fraunhofer CCPE Summit on February 8 and 9, 2023 in Munich.

In a circular plastics economy, resources can be saved, products can be intelligently designed for long service life, and end-of-life losses can be reduced. Systemic, technical and social innovations are needed to make the transition from a linear to a circular economy a success. This is what the Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE is researching in the three divisions “Materials”, “Systems” and “Business”. The cooperation of the six Fraunhofer institutes IAP, ICT, IML, IVV, LBF and UMSICHT enables a multi-stakeholder approach in which the appropriate R&D competencies are bundled.

Fraunhofer CCPE would like to present and discuss successful projects and research approaches on an international scale at the Fraunhofer CCPE Summit on February 8 and 9, 2023 in Munich. The summit is to become an international forum for exchanging ideas for solutions and innovations for a circular plastics economy.

Cross-industry collaboration - local, regional and international
Since August 2022, Prof. Manfred Renner, Institute Director of Fraunhofer UMSICHT, is the new head of Fraunhofer CCPE. He succeeds Prof. Eckhard Weidner, who has retired. “Cross-industry cooperation - very local, but also regional and international - is the elementary prerequisite for a functioning circular plastics economy. At the summit, players from all points of the compass will meet and network in order to rethink the plastics value chain together," explains Prof. Manfred Renner, adding, “We want to provide answers to the following questions:  How can we make all Circular Economy principles, i.e. the ten R-strategies, known? How can industry, science and society best cooperate in a transformation to a circular plastics economy for the greatest possible impact?”

Results of the Fraunhofer CCPE cluster so far are innovative approaches for circular business models, intelligent collection, sorting, and recycling technologies, but also new formulations for circular polymers and compounds to enable multiple recycling cycles. With the newly developed assessment tool CRL® , companies can, for example, self-assess the maturity of products or product systems with regard to the circular economy. The tool checks the extent to which a product already takes into account circular economy principles in the areas of product design, product service system, end-of-life management and circular economy, and where there is still potential for improvement.

The ability to anticipate future changes and to proactively shape the change is therefore an increasingly decisive competitive factor for modern companies. Trends are considered to be important indicators of impending

Kelheim Fibres, a leading manufacturer of viscose speciality fibres, stands out in the industry not least for its innovative strength, as evidenced by numerous awards such as the Techtextil Innovation Award 2022 in the “New Concept” category. At this year’s Global Fiber Congress Dornbirn, Innovation Manager Ilka Kaczmarek will give an insight into the innovation management of the Bavarian fibre experts in her presentation “Trend Management meets Open Innovation: Best Practice Examples from Kelheim”. Ilka Kaczmarek will show how successful product solutions were developed in a short time by focusing on customer needs and working closely with partners along the value chain.

Natalie Wunder, Project Manager at Kelheim Fibres, will explain one of these examples in detail in her presentation “Development of Menstruation Pants using Speciality Viscose Fibres”. Based on the current trend and the desire of end customers for reusable products, Kelheim Fibres was able to develop a washable and thus reusable, yet bio-based solution for feminine hygiene products.

A new fabric inspection technique for accurately detecting the most subtle of defects on patterned fabrics during high speed production has been developed by BTMA member Shelton Vision, of Leicester, UK.

The patent-pending system has been integrated into the company’s WebSpector platform and validated through factory trials on a purpose-built full scale in-house demonstration system with sophisticated fabric transport capabilities. As a result, a first system has already been ordered by a manufacturer of both plain and patterned fabrics, including camouflage, in Colombia. This follows the successful conclusion of a 21-month Innovate UK project in which techniques for the resolution of complex pattern deformations were developed by machine vision and computer scientists in the company, backed up by the machine vision and robotics department at Loughborough University.

Restrictions
Traditional methods for defect detection rely on human inspection which is ineffective, with detection rates under 65%, while the Shelton WebSpector machine vision system offers a sophisticated platform for automated defect detection of over 97%, but until now has been restricted to plain textiles.

While pattern matching and neural network approaches have previously been tried for patterned textiles, they have failed to provide a practical solution due to the extreme complexity associated with pattern matching on deformable substrates like textiles, as well as the time required to train a neural network for each pattern type.

Challenges
The challenge is that fabrics are not rigid and can be creased or stretched and are also subject to local distortion,” says Shelton Vision Managing Director and CEO Mark Shelton. “As a result, inspection without the technique we have developed, would lead to thousands of false positives. Our sophisticated pattern inspection software techniques ensure a clean image, allowing the detection of faults on fabrics running at speeds of up to a hundred metres a minute.”

The full system consists of:

• A camera and lighting system for optimum image capture at high speed and associated image processing hardware.
• Self-training software utilising statistical analysis to automate the system configuration for new textile products.
• An advanced suite of defect detection algorithms for the detection of all textile defect types.
• An AI-driven defect classification system which learns and automates defect naming in real time, as well as a real time defect grading capability based on client decision rules.
• A system for recording and retrieving complete roll map images for subsequent review and quality control.

The generation of textile roll maps with complete defect data allows for an optimised textile cut plan, improved downstream processing and quality assurance.

• Aims to tackle the immense textile waste generated in urban environments, on the back of import bans of waste materials
• Addresses the shortcomings of current textile recycling technologies, which are unsuitable for urban settings due to the use of heavy chemicals
• Technologies developed by the newly-formed RGE-NTU Sustainable Textile Research Centre will be test-bedded in RGE’s pilot urban-fit textile recycling plant, projected for completion as early as 2024

Royal Golden Eagle (“RGE”), a global group of resource-based manufacturing companies, which includes a world-leading viscose fibre producers Sateri and Asia Pacific Rayon (APR), is developing urban-fit, closed-loop textile-to-textile recycling solutions, through the newly-formed RGE-NTU Sustainable Textile Research Centre (RGE-NTU SusTex). This is a five-year research collaboration between RGE and Nanyang Technological University, Singapore (“NTU”), to accelerate innovation in textile recycling that can be deployed in urban settings. The research centre will develop new technologies to recycle textile waste into fibre and create new, next-generation eco-friendly and sustainable textiles.

This move comes on the back of the tightening of waste import bans in countries such as China, India and Indonesia, which are among the world’s largest waste processors. The stricter import bans have left cities in need of viable local textile recycling solutions to tackle the immense textile waste generated.

RGE Executive Director, Mr Perry Lim, said, “Current textile recycling technologies, which rely primarily on a bleaching and separation process using heavy chemicals, cannot be implemented due to environmental laws. At the same time, there is an urgent need to keep textiles out of the brimming landfills.” He added, “As the world’s largest viscose producer, we aim to catalyse closed-loop, textile-to-textile recycling by developing optimal urban-fit solutions that can bring the world closer to a circular textile economy.”

Globally, an estimated 90 million tonnes of textile waste is generated and disposed of every year, with less than 1% being upcycled into new clothing or other textile materials. By 2030, the amount of global textile waste, which currently accounts for almost 10% of municipal solid waste, is expected to reach more than 134 million tonnes. The textile industry is also responsible for 10% of global greenhouse gas emissions – more than international flights and maritime shipping combined.

At present, most of the available textile recycling technologies are open-loop, where textile waste is typically downcycled to lower-quality products (insulating materials, cleaning cloths, etc.) or be used in waste-to-heat recycling.

“Closed-loop textile-to-textile recycling processes, particularly chemical recycling, are still under development. Scaling up the technologies to industrial scale remains a challenge. A key bottleneck is that refabricating textile waste into fibre needs purity standards for feedstock. However, most of the clothes that we wear are made of a mixture of different synthetic and natural fibres, which makes separating the complex blends of materials challenging for effective recycling.

“Our aim is to address this industry pain point by developing viable solutions that use less energy, fewer chemicals and produces harmless and less effluents, and then potentially scale up across our global operations,” Mr Lim said.

To tackle the key challenges in closed-loop textile recycling, RGE-NTU SusTex is looking into four key research areas, namely cleaner and more energy efficient methods of recycling into new raw materials, automated sorting of textile waste, eco-friendly dye removal, and development of a new class of sustainable textiles that is durable for wear and, at the same time, lends itself to easier recycling.

Technologies developed by RGE-NTU SusTex will be test bedded at RGE’s pilot urban-fit textile recycling plant in Singapore, which is projected for completion as early as 2024. If successful, RGE has plans to replicate the plant in other urban cities within its footprint.

Um zukünftig abfallfreie Industrieprozesse realisieren und vollständig geschlossene Stoffkreisläufe schaffen zu können, bedarf es leistungsstarker und anwendungsspezifischer Separationsverfahren. Vor diesem Hintergrund plant die IWS Innovations- und Wissensstrategien GmbH für den Herbst 2022 ein Innovationsnetzwerk zum Thema "Abfallfreie Industrieprozesse durch innovative Filtrationstechnologien" und stellt die Entwicklung innovativer Filtrationstechnologien zur Rückgewinnung von Ressourcen aus Industrieprozessen in den Fokus.

Mit der aktiven Anbahnung von Partnerschaften und Projektideen innerhalb des Netzwerks sowie mithilfe einer umfangreichen Unterstützung bei der Beantragung von Fördermitteln sollen Unternehmen und Forschungsinstitution auf dem Weg zu erfolgreichen Kooperationsprojekten unterstützt werden.

Um das Potential der Kreislaufwirtschaft zu nutzen, bringt das Innovationsnetzwerk zum Thema "Abfallfreie Industrieprozesse durch innovative Filtrationstechnologien" Kompetenzen aus den Umwelt- und Nanowissenschaften mit mittelständischen Herstellern und Dienstleistern aus den Zielbranchen Chemische Industrie, Abwasseraufbereitung und Umwelttechnik zusammen. Die stark interdisziplinäre Ausrichtung soll es den Akteuren ermöglichen, Synergiepotentiale zu nutzen und gemeinsam innovative Lösungen mit hohen Marktchancen umzusetzen.

Im Rahmen gemeinsamer Forschungs- und Entwicklungsvorhaben zwischen Unternehmen und Forschungseinrichtungen sollen innovative Filtrationstechnologien entwickelt und so mittelständischen Unternehmen den Zugang zu neuen und individuellen Lösungen für eine nachhaltige Verwendung von stofflichen Ressourcen in Industrieprozessen ermöglicht werden.

Freudenberg Performance Materials (Freudenberg) will be presenting Evolon® eco-friendly microfiber reinforcement material for leather goods that is manufactured in Europe with no solvent and no chemical binder at the Lineapelle international trade show for the leather industry. Another sustainability highlight is binder-free strobel material made from 100% recycled PET for the shoe industry. The company will also be showing a nonwoven crimping material that meets the increasing demands of manufacturers and consumers alike in the footwear market.

Evolon® contains 80% recycled PET. It is produced at Freudenberg’s facility in Colmar, France, where the manufacturing process is highly sustainable: it is certified to STeP by OEKO-TEX® and fully complies with the DETOX TO ZERO by OEKO-TEX® criteria. In addition, shorter transport routes help to secure supply chains for players in the European leather goods industry.

The binder-free strobel material is made from 100% recycled PET. It is GRS-certified for reliable traceability. The GRS certification recognizes the share of recycled materials in the strobel material. This allows customers to calculate the total amount of recycled material in shoes. Moreover, the mono-component material itself is fully recyclable. In terms of performance, the material is lightweight and also demonstrates a high tensile strength.

Made from nonwoven fabric, the innovative crimping material optimally combines high permanent moldability and shape retention with flexibility and suppleness. This crimping material enables manufacturers to reduce their production costs, while consumers benefit from increased comfort. Compared to conventional knitted fabric-based crimping materials, the nonwoven crimping material offers multi-directional stretching properties, improved fitting, greater design freedom and reduced weight.
