RHEON LABS: Fibre with unique strain-rate sensitive characteristics

RHEON LABS, a fast-growing materials technology company based in Battersea, London, has completed an extensive 6 month trial with FET, a world leader in laboratory and pilot meltspinning equipment. Backed by a £173,000 grant from Innovate UK for feasibility studies, RHEON LABS has further developed its RHEON™ technology, a reactive polymer that dynamically stiffens when subjected to force. The technology can control energy of any amplitude or frequency, from small vibrations to forces at ballistic-speeds and therefore has a wide range of applications.
 
This Innovate UK Smart Grant-backed project aims to develop a hyper viscoelastic fibre from RHEON™ which displays high strain-rate sensitive properties. Creating a fibre with unique strain-rate sensitive properties will be a world first. It will enable the creation of a 'breakthrough-generation' of stretch textiles that can actively absorb, dampen and control energy during movement, rather than simply acting as a spring.

It will enable the creation of a 'breakthrough-generation' of stretch textiles that can actively absorb, dampen and control energy during movement, rather than simply acting as a spring.

For close-fitting activewear and sports bras, the ability to actively control muscle mass or soft tissue movement during exercise will be a game-changing advancement. It will allow brands to engineer garments that relax during everyday use but actively stiffen during exercise for improved support and performance.
The Innovate UK grant was awarded under the category of Hyper-Viscoelastic Fibre Extrusion for Textile Manufacture. Fibre Extrusion Technology Limited (FET) enabled the customer trials at its bespoke Fibre Development Centre in Leeds, England using its in-house FET-103 Monofilament meltspinning facilities, in harness with RHEON and FET technical operatives. The next phase will be to upscale the trials of preferred materials on RHEON’s own new FET-103 meltspinning line, with FET’s continued support and expertise on hand.
 
Creating a fibre with unique strain-rate sensitive characteristics could be as radical a change in the market as the initial introduction of stretch fibre with the launch of Lycra™. The textiles would have a multitude of beneficial properties and would provide significantly less compression in the garment than conventional materials, substantially improving user comfort, support and performance.

Flocking is an application method in which tiny fibers are piled on to the surface of a textile, creating textures for both decorative and functional purposes. CELLIANT Viscose in a flocked material has many potential applications in the medical field for tapes, bandages, braces and orthopedic products, home textiles and decor, dog beds, clothing, and more.  CELLIANT features natural, ethically sourced minerals, which convert body heat into infrared energy for increased local circulation and cellular oxygenation.  These CELLIANT minerals are then embedded into viscose plant-based fibers. The Viscose fibers are then flocked onto a base material. CELLIANT Viscose provides all the benefits of being a viscose fiber — lightweight, soft, highly breathable, excellent moisture management — as well as the fiber enhancements from CELLIANT infrared technology.

CELLIANT Viscose is the first IR flocked material that Spectro is producing. CELLIANT Viscose also represents a further expansion into sustainable products for Spectro. In addition, Spectro products are made in the USA, as is CELLIANT’s mineral blend.

A take-back scheme where consumers can wear it down and then return it by scanning a QR code via the product so it can be remade. Moving adidas closer to its goal to help end plastic waste.

It’s currently estimated that just under 1% of all textiles worldwide are recycled into new textiles, so it’s vital the textile industry comes together to learn and knowledge-share. Scheduled across a three-year period, the consortium which includes partners such as Frankenhuis have collected and sorted post-consumer end-of-life textiles, which using pioneering Infinited Fiber technology have been regenerated into a new man-made cellulosic fiber called Infinna™ - which looks and feels just like virgin cotton. This is then turned into a yarn blended with organic cotton, for garment production.

Designing the tracksuit, made using viscose (60% viscose, 40% organic cotton) as a consortium member took the process from a linear to a circular model , as the apparel’s function and style were of equal focus to the garment’s end of life existence.

At the end of the project, consortium partner Aalto University, a Finnish multidisciplinary community specialising in science, art, technology , and design, will distribute learnings with the industry and bring this potential circular design solution to the ever-eco-conscious consumer.

World Natural Fibre Update September 2022

World Natural Fibre Production in 2022 is estimated at 32.6 million tonnes, down 1.1 million tonnes from the estimate one month ago. Production reached 33.3 million tonnes in 2021 and 31.6 million in 2020.

A drought in Texas where over half of cotton produced in the United States is grown, and flooding in Pakistan, the fifth largest cotton producer, account for the decline (www.ICAC.org).

A drought in Texas where over half of cotton produced in the United States is grown, and flooding in Pakistan, the fifth largest cotton producer, account for the decline (www.ICAC.org).

  • Nearby cotton futures on the Intercontinental Exchange rose 14% from the end of July and finished August at $2.60 per kilogram.
  • The Eastern Market Indicator of wool prices in Australia, fell 1% from mid-July to mid-August to US$9.27 per kilogram.
  • Prices of jute fibre in India quoted by the Jute Balers Association (JBA) at the end of August converted to US$ fell 4% from a month earlier to 79 cents per kilogram.
  • Prices of silk in China equalled US$ 28.7 per kilogram at the end of August, compared with US$29.5 per kilogram in July 2022, a change of 3%.
  • Coconut coir fibre in India held at US cents 21 per kilogram in August.

World production of jute and allied fibres is estimated unchanged at 3.2 million tonnes in 2022 compared with 2021. High market prices in 2021 motivated farmers to expand planted area in both Bangladesh and India, but dry weather during June and July will limit yields per hectare. Normal monsoon rains resumed in South Asia during August, too late for the 2022 jute crop (https://www.wgc.de/en/).

Production of coir fibre rose by an average of 18,000 tonnes per year during the past decade, and production was at a record high of 1.12 million tonnes in 2021. Production is expected to remain high in 2022.

Flax has also been trending upward, rising by an average of 27,000 tonnes per year, and production in 2022 is estimated to remain above one million tonnes.

World wool production is forecast up by 5% in 2022 to 1.09 million tonnes (clean), the highest since 2018. Wetter weather in the Southern Hemisphere, following eight years of drought, is allowing farmers to rebuild herds (https://www.wool.com/market-intelligence/).

Natural fibres are heavily-traded commodities, and supply chain disruptions are causing significant economic losses as freight costs remain high and deliveries are delayed.

About 40% of world cotton production moves as fibre in international trade each season. Over half of world jute production moves as fibre or product, and around 55% of world wool production is exported as raw wool. Abaca, flax, and sisal are also heavily traded.

Most natural fibre exports traverse back-haul ocean freight routes from the Western Hemisphere to East Asia and the Middle East, from South Asia to East Asia and Europe, from Africa to East Asia and the Middle East, and from Australia and South Africa to China. Such routes are relatively underserved in the best of times, and reduced sailings since the start of Covid are restricting trade volumes.

As of the end of August, Freightos (https://fbx.freightos.com/) quoted the cost of moving a 40’ container from the United States West Coast to East Asia at $793, compared with $1,020 in March 2022. Nevertheless, average freight costs on back -haul routes used by natural fibres remain approximately triple their pre-covid levels. In addition to ocean freight costs, inland transportation is also affected by high fuel prices and a lack of containers. As one example, charges for inland handling of export containers in Bangladesh, the largest exporter of raw jute, increased by 48 per cent during August.

Lenzing also switches to green electricity at its Chinese site

The Lenzing Group, a leading provider of wood-based specialty fibers, is expanding its global clean electricity portfolio by gradually transitioning to green energy at its production site in Nanjing. This will enable its Chinese subsidiary Lenzing Nanjing Fibers to use electricity derived solely from renewable sources from 2023 onwards and reduce the site’s carbon emissions by 100,000 tonnes annually. Lenzing only recently announced the transition to green electricity at its Indonesian production facility.

In 2019, Lenzing became the first fiber producer to set a target of halving its carbon emissions by 2030 and becoming climate neutral by 2050. This carbon reduction target has been recognized by the Science Based Targets Initiative. In Nanjing, Lenzing is currently investing in cutting its carbon emissions and converting a standard viscose production line to 35,000 tonnes of TENCEL™ branded modal fibers. Thanks to this move, the Chinese site will exclusively produce eco-friendly specialty fibers.

Ionofibres a new track for smart and functional textiles

Electronically conductive fibres are already in use in smart textiles, but in a recently published research article, ionically conductive fibres have proven to be of increasing interest. The so-called ionofibres achieve higher flexibility and durability and match the type of conduction our body uses. In the future, they may be used for such items as textile batteries, textile displays, and textile muscles.

The research project is being carried out by doctoral student Claude Huniade at the University of Borås and is a track within a larger project, Weafing, the goal of which is to develop novel, unprecedented garments for haptic stimulation comprising flexible and wearable textile actuators and sensors.

In Claude Huniade’s project, the goal is to produce conductive yarns without conductive metals.
"My research is about producing electrically conductive textile fibres, and ultimately yarns, by coating non-metals sustainably on commercial yarns. The biggest challenge is in the balance between keeping the textile properties and adding the conductive feature," said Claude Huniade.

"My research is about producing electrically conductive textile fibres, and ultimately yarns, by coating non-metals sustainably on commercial yarns. The biggest challenge is in the balance between keeping the textile properties and adding the conductive feature," said Claude Huniade.

Currenty, the uniqueness of his research leans towards the strategies employed when coating. These strategies expand to the processes and the materials used.

Uses ionic liquid
One of the tracks he investigates is about a new kind of material as textile coating, ionic liquids in combination with commercial textile fibres. Just like salt water, they conduct electricity but without water. Ionic liquid is a more stable electrolyte than salt water as nothing evaporates.

"The processable aspect is an important requirement since textile manufacturing can be harsh on textile fibres, especially when upscaling their use. The fibres can also be manufactured into woven or knitted without damaging them mechanically while retaining their conductivity. Surprisingly, they were even smoother to process into fabrics than the commercial yarns they are made from," explained Claude Huniade.

Ionofibres could be used as sensors since ionic liquids are sensitive to their environment. For example, humidity change can be sensed by the ionofibers, but also any stretch or pressure they are subjected to.

"Ionofibres could truly shine when they are combined with other materials or devices that require electrolytes. Ionofibres enable certain phenomena currently limited to happen in liquids to be feasible in air in a lightweight fashion. The applications are multiple and unique, for example for textile batteries, textile displays or textile muscles," said Claude Huniade.

Needs further research
Yet more research is needed to combine the ionofibres with other functional fibres and to produce the unique textile devices.

How do they stand out compared to common electronically conductive fibres?
"In comparison to electronically conductive fibres, ionofibers are different in how they conduct electricity. They are less conductive, but they bring other properties that electronically conductive fibers often lack. Ionofibres achieve higher flexibility and durability and match the type of conduction that our body uses. They actually match better than electronically conductive fibres with how electricity is present in nature," he concluded.

Die Bremer Baumwollbörse und das Faserinstitut Bremen e.V. laden gemeinsam am 29. und 30. September zur 36. International Cotton Conference Bremen ein. Unter dem Motto „Cotton Decoded“ wird den Tagungsteilnehmern sowohl in Bremen vor Ort als auch online über eine Tagungsplattform ein anspruchsvolles Programm mit aktuellen Vorträgen und lebhaften Diskussionsrunden geboten.

Die Europäische Union nimmt Textilunternehmen mit ihrem geplanten Lieferkettengesetz in die Verantwortung. Dies erfordert ein Umdenken im Lieferkettenmanagement. Zusätzliche Herausforderungen entstehen durch Fast Fashion, kürzere Zykluszeiten der Textil- und Bekleidungsindustrie sowie Forderungen nach Transparenz und mehr Nachhaltigkeit. Hierbei spielen auch Fragen der für ein Produkt notwendigen Baumwollqualität eine wesentliche Rolle. Mit Methoden der Rückverfolgbarkeit und der Transparenz in Lieferketten sowie den Möglichkeiten zu Beurteilung von Baumwollqualität beschäftigt sich die Internationale Baumwolltagung in ihren Sessions ‚Traceability‘ und ‚Cotton Quality und Testing‘.

Digitale Ökosysteme – was in Zukunft möglich ist!
Gesine Köppe, wissenschaftliche Mitarbeiterin am Institut für Textiltechnik der RWTH Aachen lässt die Konferenzteilnehmer in das Modell eines komplett digital vernetzten Ökosystems eintauchen. Es bietet völlige Transparenz mit der Möglichkeit der Rückverfolgbarkeit innerhalb der gesamten textilen Produktions- und Lieferkette vom Baumwollfeld bis zum Textil- und Bekleidungseinzelhandel. Die Lösung liegt laut Gesine Köppe in der Anwendung einer ‚Distributed Ledger-Technologie‘ mit der Möglichkeit einer gezielten Dokumentation von ausgewählten Transaktionen, wie man sie in ähnlicher Form auch von Blockchains kennt. Jeder Teilnehmer der Supply Chain gibt für das gesamte Netzwerk sichtbar relevante Informationen in ein dezentral geführtes digitales ‚Hauptbuch‘, wie man es aus der Buchführung kennt, ein. Während des Projekts wird ein ständiges Dokumentations- und Informationssystem eingerichtet, um die vertikale und horizontale Integration der Technologien zu gewährleisten. Somit soll der Textil- und Bekleidungsindustrie ein Anreiz durch Kooperation geboten werden.

Baumwolle Usbekistan: Rückverfolgbarkeit von Feld bis zur Spinnerei
Dr. Rinat Gulyaev, Direktor beim Cotton Science-Innovation Center, Tashkent in Usbekistan, stellt in seinem Vortrag ein Projekt vor, das darauf abzielt, Baumwolle und Baumwollprodukte durch digitale Technologie zu identifizieren und zu kennzeichnen. Damit soll eine Rückverfolgbarkeit für die Teilnehmer der Lieferkette von der Baumwollfarm bis zur Textilfabrik geschaffen werden. Dabei kommen moderne internationale Standards und bewährte Verfahren zum Einsatz. Besonderer Wert wird hierbei auf das Zusammenspiel der Digitaltechnologie mit anderen Plattformen im Kontext der digitalen Transformation der usbekischen Wirtschaft gelegt.

Effektivität lokal vernetzter Wertschöpfungsketten
Miriam Paris, Bayer Crop Science, USA, stellt in ihrem Vortrag ein spezielles ‚Field to Closet‘ -Projekt vor, bei dem in Georgia angebaute Baumwolle in Produkten im Medizinbereich Verwendung fand. Die Besonderheit: Die Stoffe für die Berufsbekleidung sind mit dem PROTX2® AV-Schutz des US-Unternehmens Intelligent Fabric Technologies N.A. ausgerüstet. Es handelt sich hierbei um eine antimikrobielle Technologie, die das Wachstum von Bakterien hemmt. Ein Thema, das für den Medizinbereich von hoher Bedeutung ist.

Textil-Tracker: Aus welcher Baumwolle besteht mein T-Shirt?
Gesicherte Herkunftsnachweise sind in der textilen Kette von wesentlicher Bedeutung. Karin Ratovo, wissenschaftliche Mitarbeiterin der Hochschule Niederrhein, Mönchengladbach sowie Markus Bonner, Agroisolab GmbH, Jülich, werden zur Tagung die Untersuchungsergebnisse des Projektes "Textile-Tracker" vorstellen. Agroisolab ist eines der führenden europäischen Laboratorien im Bereich Isotopenanalytik. Im Rahmen der Forschungsarbeit am Projekt wurde analysiert, ob chemische Signaturen von Baumwollfasern in den üblichen Textilverarbeitungsschritten erhalten bleiben. Bei erfolgreicher Validierung besteht die Möglichkeit, eine georeferenzierte Herkunftsdatenbank für Baumwolle und Textilien aufzubauen.

15 Jahre CSITC-Rundtest: Ergebnisse und Nutzen
Seit 2007 organisiert das Faserinstitut Bremen e.V. in Kooperation mit dem International Cotton Advisory Committee (ICAC) und dem US-Landwirtschaftsministerium (USDA) Rundtests zur Standardisierung von Instrumenten-Tests für Baumwolle im Rahmen des Committee on Standardized Instrument Testing of Cotton (CSITC). Es geht um die Überprüfung und Harmonisierung von High Volume-Instrumenten (HVI). Die Ergebnisse von mit HVI-Technik durchgeführten Baumwolltests sind u. a. im Baumwollhandel oder bei Spinnereien gefragt. Deshalb sollte die Prüfung einer bestimmten Baumwollqualität in zertifizierten Laboren international annähernd gleiche Ergebnisse aufweisen. Axel Drieling, Senior Manager Cotton und Mitglied des Vorstands beim Faserinstitut, sowie der neue Leiter der CSITC Task Force und Chefberater für das australische Unternehmen Textile Technical Services, Geelong, Marinus van der Sluijs, stellen die erzielten Fortschritte bei den Tests der letzten 15 Jahre vor. Van der Sluijs strebt an, die Anzahl der Teilnehmer am Rundtest gerade auch auf Seiten der Baumwollverarbeiter zu erhöhen. Dazu werden die Vorteile der Harmonisierung und Überprüfung für die Baumwollproduktion, für den Handel und für die Spinnereien genannt und faktisch untermauert.

Recycling und Faserqualität
Stephan Baz, Leiter des Bereichs Stapelfaser-Technologie am Deutschen Institut für Textil- und Faserforschung, Denkendorf (DIFT) stellt zur Tagung Zwischenergebnisse eines Projekts vor, das Lösungen für die Bewertung von für Reyclingzwecke zerrissene Materialien aus Baumwolle oder synthetischen Fasern mittels bewährter Rohstoffklassifizierung bietet. Im Zuge der Nachhaltigkeitsdebatte ist die Wiederverwertung von Textilien im Rahmen einer Kreislaufwirtschaft inzwischen ein viel diskutiertes Thema. Ziel des Projektes ist es, durch die Optimierung notwendiger Reißprozesse ein für den Spinnprozess qualitativ brauchbares Garn mit möglichst geringem Eigenschaftsverlust herzustellen.

Faserqualität und Entkörnung
Marinus van der Sluijs wirft mit seinem zweiten Vortrag einen Blick auf die Effektivität verschiedener Entkörnungsverfahren bzw. einzelner Prozessstufen bei der Reinigung von Saatbaumwolle. Parallel dazu wurde überprüft, welche Auswirkungen diese konkret auf die Faserqualität haben.
Laut Studie beträgt der durchschnittliche Schmutzanteil von angelieferter Saatbaumwolle in der Regel weniger als 10 Prozent. Im Reinigungsprozess können 20 bis 40 Prozent der Verunreinigungen entfernt werden. Je nach Verfahren fallen aber wesentliche Qualitätsmerkmale wie Längengleichheit, Kurzfaseranteil, Nissenanteil, Dehnfähigkeit, Festigkeit, Feinheit und Reife durchaus unterschiedlich aus. Bei der Auswahl von Baumwolle lohnt es sich, einen Blick darauf zu werfen.

SGL Carbon increases sales and earnings guidance again for 2022

Due to the continued good business development, especially in the Carbon Fibers Business Unit, SGL Carbon SE is increasing its Group sales and earnings guidance for the current fiscal year and now expects Group sales of approximately €1.2 billion (previously: approximately €1.1 billion). The company expects to achieve adjusted EBITDA (EBITDA pre = earnings before interest, taxes, depreciation and amortization before one-off effects and non-recurring items) of €170 - €190 million (previously: €130 - €150 million) in 2022.

Based on lower prices for acrylonitrile as main raw material of the Business Unit Carbon Fibers as well as higher than expected customer demand for acrylic and carbon fibers combined with consistently good production capacity utilization and capability, the management of SGL Carbon SE assumes an improved earnings development of this Business Unit.

Based on lower prices for acrylonitrile as main raw material of the Business Unit Carbon Fibers as well as higher than expected customer demand for acrylic and carbon fibers combined with consistently good production capacity utilization and capability, the management of SGL Carbon SE assumes an improved earnings development of this Business Unit.

SGL Carbon assumes that the factors mentioned will continue at least until the end of the year and that the earnings situation of the Business Unit Carbon Fibers will exceed previous expectations. Combined with the continued good business development of the other three Business Units (Graphite Solutions, Process Technology and Composite Solutions), an improvement in the sales and earnings situation at Group level is expected.

In line with the forecast increase for adjusted EBITDA (EBITDA pre) to between €170 and €190 million (previously: €130 - €150 million), the company is forecasting adjusted EBIT (earnings before interest and taxes and before one-off effects and non-recurring items) of between €110 and €130 million (previously: €70 - €90 million). The forecast for return on capital employed (ROCE) of originally 7% - 9% has been raised to 10% to 12% corresponding to the development of earnings. The expectations for free cash flow (significantly below previous year's level of €111.5 million) remain unaffected by the expected improvement in sales and earnings.

The updated forecast for fiscal 2022 has been prepared on the basis of the currently prevailing market environment and assumes no deterioration in the general conditions, in particular due to the war in Ukraine and its consequences for the global economy.
 
The definition of key figures used in this release is aligned to the Annual Report 2021. There were no changes in the scope of consolidation or accounting methods compared with the previous guidance.

AZL: Plastic-based multi-material solutions for cell-to-pack battery enclosures

The future of e-mobility will be determined in particular by safe battery enclosures. As batteries for electric vehicles become more performant, higher volumetric energy density plays a crucial role. If more energy is to be stored in less installation space, new material and design solutions are required. The development of suitable enclosures made of safe and highly robust lightweight materials is also required. This is a case for the Aachen Centre for Integrative Lightweight Production (AZL). A project on cell-to-pack battery enclosures for battery-electric vehicles, which has been eagerly awaited in the industry, will start in October this year there.

The future of e-mobility will be determined in particular by safe battery enclosures. As batteries for electric vehicles become more performant, higher volumetric energy density plays a crucial role. If more energy is to be stored in less installation space, new material and design solutions are required. The development of suitable enclosures made of safe and highly robust lightweight materials is also required. This is a case for the Aachen Centre for Integrative Lightweight Production (AZL). A project on cell-to-pack battery enclosures for battery-electric vehicles, which has been eagerly awaited in the industry, will start in October this year there.

The design of battery housings is crucial for safety, capacity, performance, and economics. The Cell-to-Pack project, which is starting now, will focus on developing concepts for structural components and for producing them based on a variety of materials and design approaches. The concepts will be compared in terms of performance, weight and production costs, creating new know-how for OEMs, producers and their suppliers throughout the battery vehicle value chain. Companies are now invited to participate in this new cross-industry project to develop battery enclosure concepts for the promising and trend-setting cell-to-pack technology.

The basis for the project is the lightweight engineering expertise of the AZL experts, which they have already demonstrated in previous projects for multi-material solutions for module-based battery housings. Together with 46 industry partners, including Audi, Asahi Kasei, Covestro, DSM, EconCore, Faurecia, Hutchinson, Johns Manville, Magna, Marelli and Teijin, 20 different multi-material concepts were optimized in terms of weight and cost and compared with a reference component made from aluminum. All production steps were modelled in detail to obtain reliable cost estimates for each variant. Result: depending on the concept, 20% weight or 36% cost savings potential could be identified by using multi-material composites compared to the established aluminum reference.

It is expected that the design concept of battery enclosures will develop in the direction of a more efficient layout. In this case, the cells are no longer combined in modules in additional production steps, but are integrated directly into the battery housing. The elimination of battery modules and the improved, weight-saving use of space will allow for higher packing density, reduced overall height and cost saving. In addition, various levels of structural integration of the battery housing into the body structure are expected. These new designs bring specific challenges, including ensuring protection of the battery cells from external damage and fire protection. In addition, different recyclability and repair requirements may significantly impact future designs. How the different material and structural options for future generations of battery enclosures for the cell-to-pack technology might look like and how they compare in terms of cost and environmental impact will be investigated in the new AZL project. In addition to the material and production concepts from the concept study for module-based battery enclosures, results from a currently ongoing benchmarking of different materials for the impact protection plate and a new method for determining mechanical properties during a fire test will also be incorporated.

The project will start on October 27, 2022 with a kick-off meeting of the consortium, interested companies can still apply for participation until then.

RGE: Closed-loop urban-fit textile-to-textile recycling solutions in Singapore

  • 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.

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.

No Planet, no Fashion
Für den international operierenden Modekonzern HUGO BOSS stehen Nachhaltigkeit und unternehmerisches Handeln in keiner Weise im Widerspruch zueinander. Sie sind unverzichtbar miteinander verzahnt. Andreas Streubig, Senior Vice President Global Corporate Responsibility & Public Affairs, wird in seinem Vortrag deutlich machen, wie HUGO BOSS Nachhaltigkeit als wesentliches Leitprinzip seiner als „CLAIM 5“ definierten technologiegesteuerten Wachstumsstrategie implementiert hat. Den fünf Claims ‚Boost Brands‘, Product is King‘, Lead in Digital‘, Rebalance Omnichannel‘ und ‚Organize for Growth‘ liegt ein ganzheitliches und handlungsanweisendes Nachhaltigkeitsverständnis zugrunde. In diesem Sinne ist Nachhaltigkeit ein Zeichen für die Zukunftsfähigkeit des Unternehmens, verbunden mit intensiven Transformations- und Innovationsprozessen. Um gemeinsam entscheidende Verbesserungen zu erreichen, engagiert sich HUGO BOSS in unterschiedlichen Initiativen wie ZDHC, UNFCCC, FLA und beim Textilbündnis.
 
Nachhaltigkeit braucht Transparenz
Dr. Gary Adams ist Präsident und CEO des US-amerikanischen National Cotton Council. Seine Organisation vertritt die US-Baumwollindustrie in ihrer gesamten Bandbreite, bestehend aus Landwirten, Genossenschaften, Entkörnungsunternehmen, Dienstleistern sowie dem Handel. Nachhaltigkeitsaspekte spielen dabei eine wesentliche Rolle. In seinem Vortrag bietet Gary Adams einen Überblick über die von seiner Organisation mitinitiierte Nachhaltigkeitsinitiative U.S. Cotton Trust Protocol.
Ein wichtiges Ziel des Protocols besteht darin, eine kontinuierliche, messbare Verbesserung bedeutender Nachhaltigkeitskennzahlen zu erreichen. Diese Daten werden völlig transparent an Marken und Einzelhändler zur Information der Endkonsumenten weitergegeben. In der Präsentation werden der Gesamtumfang und die Struktur der Initiative sowie ein Überblick über die aggregierten Nachhaltigkeitsdaten der teilnehmenden Erzeuger vorgestellt.
 
Ökobilanz: T-Shirts aus US-Baumwolle
Roger Gilmartin ist Fachberater für Großbritannien im technischen Team von Cotton Council International (CCI). Er berichtet über die Ergebnisse eines Forschungsprojektes, in dem es darum ging, eine Umweltbilanz für die Herstellung und Vermarktung von T-Shirts aufzustellen. Bisher veröffentlichte Ökobilanzen konzentrierten sich auf das Geschehen innerhalb der Landwirtschaft. Die von ihm vorgestellte aktuelle Studie schließt ergänzend dazu alle Prozesse mit ein, die in einer Textil- und Bekleidungsfabrik in Bangladesch ablaufen. Die Studie liefert fundierte Daten über den Beitrag der Fertigungsprozesse zur globalen Erwärmung, über die Gefahren einer Schädigung der Ozonschicht, zum Entstehungspotential von Sommersmog durch fotochemische Reaktionen, der Süßwasser-Ökotoxität, der Entstehung sauren Regens sowie der übermäßigen Anreicherung der Gewässer durch Rückstände z. B. ausgelöst durch übermäßigen Einsatz von Pestiziden oder Phosphor- und Stickstoffverbindungen.
 
Nachhaltigkeit: Der technische Blick
Bekleidung aus Baumwoll-/Chemiefasermischungen im Waschprozess

Im Zusammenhang mit Mikroplastik textiler Herkunft befasst sich die wissenschaftliche Forschung hauptsächlich mit Produkten aus reinen Chemiefasern. Doch Baumwolle ist eine der am häufigsten verwendeten Naturfasern für Kleidungsstücke. Hinzukommen viele Mischgewebe. Im Mittelpunkt des Vortrags von Dr. Claudia Heller, ehemalige wissenschaftliche Mitarbeiterin an der Hochschule für Technik und Wirtschaft in Berlin, jetzt Bosch Siemens Hausgeräte BSH, stehen die Ergebnisse einer Waschstudie. Hierbei wurde ein Hemd und ein T-Shirt mit unterschiedlicher Materialzusammensetzung und Stoffkonstruktion nach einem bestimmten Standard haushaltsnah einem wiederholten Waschprozess ausgesetzt.
 
Die Ergebnisse zeigen die Veränderung der Fasereigenschaften durch Einfluss von Waschmittel, Schmutz und Kalk. Anhand der Analysemethode lässt sich zeigen, dass nur ein kleiner Teil der Filterrückstände bei der Kaskadenfiltration des Grauwassers der Waschmaschine Chemiefasern sind und welche Anteile an Baumwollfasern, Waschmittel und Schmutz im Haushaltswaschprozess vorkommen.
 
Biologische Abbaubarkeit: Was passiert mit gefärbter Baumwolle?
Die Verschmutzung der Umwelt durch Mikrofasern ist ein großes Problem mit vielen unkalkulierbaren Folgen. Fasern, die von Textilien abgeschieden werden, tragen zum Problem bei. In den letzten vier Jahren wurde viel unternommen, um den biologischen Abbau von Baumwollfasern in der natürlichen Umwelt zu untersuchen. Mary Ankeny, Vice President Product Development and Implementation bei Cotton Incorporated, USA informiert in ihrem Vortrag über die Ergebnisse der biologischen Abbaubarkeit von gefärbten und veredelten Baumwolltextilien in unterschiedlichen natürlichen Umgebungen. Insbesondere wurden die Abbauprodukte der Chemikalien untersucht, die verwendet werden, um Baumwollkleidung Farbe und spezielle Eigenschaften zu verleihen.
