From the Sector

At this year's JEC World 2024 from 5 to 7 March, KARL MAYER GROUP will be exhibiting with KARL MAYER Technical Textiles and its STOLL Business

One focus of the exhibition will be non-crimp fabrics and tapes made from bio-based yarn materials for the reinforcement of composites.

"While our business with multiaxial and spreading technology for processing conventional technical fibres such as carbon or glass continues to do well, we are seeing increasing interest in the processing of natural fibres into composites. That's why we have a new product in our trade fair luggage for the upcoming JEC World: an alpine ski in which, among other things, hemp fibre fabrics have been used," reveals Hagen Lotzmann, Vice President Sales KARL MAYER Technische Textilien.

The winter sports equipment is the result of a subsidised project. The hemp tapes for this were supplied by FUSE GmbH and processed into non-crimp fabrics on the COP MAX 5 multiaxial warp knitting machine in the KARL MAYER Technical Textiles technical centre.

The STOLL Business Unit will be focussing on thermoplastic materials. Several knit to shape parts with a textile outer surface and a hardened inner surface will be on display. The double-face products can be made from different types of yarn and do not need to be back-moulded for use as side door panels or housing shells, for example. In addition, the ready-to-use design saves on waste and yarn material.

CARBIOS and De Smet Engineers & Contractors (DSEC), a provider of Engineering, Procurement and Construction services in the biotech’s and agro-processing industries, announce their collaboration to spearhead the construction of the world's first PET biorecycling plant. Under the agreement, De Smet has been entrusted with the project management and detailed engineering, including procurement assistance and CARBIOS partners’ management, to ensure the execution of the plant's construction in Longlaville, France, due for commissioning in 2025.  CARBIOS’ first commercial facility will play a key role in the fight against plastic pollution by offering an industrial-scale solution for the enzymatic depolymerization of PET waste to accelerate a circular economy for plastic and textiles.

With over 70 members of De Smet's expert team dedicated to the project and working alongside CARBIOS teams, the collaboration aims to guarantee the project timeline and budget while upholding quality, safety, health, and environmental standards. Construction is currently underway and on schedule.

Many end-users now expect recycled materials to be in textile products they purchase – and this is driving innovation throughout the industry. However, there are still many technical and economic issues facing yarn and fabric producers using recycled resources. Members of the Swiss Textile Machinery Association offer some effective solutions to these challenges.

Synthetic recycled materials such as PET can usually be treated similarly to new yarn, but there are additional complexities where natural fibres like wool and cotton are involved. Today, there’s a trend towards mechanically recycled wool and cotton fibres.

Spinning recycled cotton
The use of mechanically recycled fibres in spinning brings specific quality considerations: they have higher levels of short fibres and neps – and may often be colored, particularly if post-consumer material is used. It’s also true that recycled yarns have limitations in terms of fineness. The Uster Statistics 2023 edition features an extended range of fibre data, supporting sustainability goals, including benchmarks for blends of virgin and recycled cotton.
In general, short fibres such as those in recycled material can easily be handled by rotor spinning machines. For ring spinning, the shorter the fibres, the more difficult it is to guide them through the drafting zone to integrate them into the yarn body. Still, for wider yarn counts and higher yarn quality, the focus is now shifting to ring spinning. The presence of short fibres is a challenge, but Rieter offers solutions to address this issue.

Knitting recycled wool
For recycling, wool fibres undergo mechanical procedures such as shredding, cutting, and re-spinning, influencing the quality and characteristics of the resulting yarn. These operations remove the natural scales and variations in fibre length of the wool, causing a decrease in the overall strength and durability of the recycled yarn. This makes the yarn more prone to breakage, especially under the tension exerted during knitting.

Adapting to process recycled materials often requires adjustments to existing machinery. Knitting machines must be equipped with positive yarn suppliers to control fibre tension. Steiger engages in continuous testing of new yarns on the market, to check their suitability for processing on knitting machines. For satisfactory quality, the challenges intensify, with natural yarns requiring careful consideration and adaptation in the knitting processes.

From fibres to nonwovens
Nonwovens technology was born partly from the idea of recycling to reduce manufacturing costs and to process textile waste and previously unusable materials into fabric structures. Nonwovens production lines, where fibre webs are bonded mechanically, thermally or chemically, can easily process almost all mechanically and chemically recycled fibres.

Autefa Solutions offers nonwovens lines from a single source, enabling products such as liners, wipes, wadding and insulation to be produced in a true closed loop. Fibres are often used up to four times for one product.

Recycling: total strategy
Great services, technology and machines from members of Swiss Textile Machinery support the efforts of the circular economy to process recycled fibres. The machines incorporate the know-how of several decades, with the innovative power and quality standards in production and materials.
Stäubli’s global ESG (environmental, social & governance) strategy defines KPIs in the context of energy consumption, machine longevity and the recycling capacity in production units worldwide, as well in terms of machinery recyclability. The machine recyclability of automatic drawing in machines, weaving systems and jacquard machines ranges from 96 to 99%.

More than 82 companies, businesses and social organizations – including AkzoNobel – are involved in a major Dutch research program focused on developing new technologies that will help solve some of today’s societal challenges.
 
Seven broad consortia have been established as part of the government-funded “Perspectief” program, with AkzoNobel set to play a leading role in the SusInkCoat project, which will explore how to make inks and coatings more sustainable.

The company will work together with private partners and other societal stakeholders to develop new materials, processes and applications to improve the durability, functionality and recyclability of coatings, thin films and inks. The program, which will run for the next five years, is backed by the Ministry of Economic Affairs and Climate Policy and the Dutch Research Council (NWO).

“Our discussions about collaborating with our SusInkCoat partners have been very positive,” says AkzoNobel’s R&D Director of Scientific Academic Programs, André van Linden, who is also the co-lead of SusInkCoat. “We’re all facing the same societal challenges – how to become more circular – and we’re looking for the same solutions in different application areas. But we’ve never done that together for this specific research topic, so we need an ecosystem to help us solve these challenges.
 
Van Linden adds that the program – one of many R&D projects the company is involved with – will also support AkzoNobel’s ambition to achieve 50% less carbon emissions in its own operations – and across the value chain – by 2030.
 
 “We want to make the recyclability of materials - such as furniture, building materials and steel constructions - easier by introducing functionalities like self-healing, higher durability and triggered release,” he continues. “The more you can leave the materials in their original state, the more sustainably you can operate.”

AkzoNobel will be collaborating with Canon, Evonik, GFB, PTG and RUG Ventures, who together possess extensive knowledge of market demands, supply chains and production processes. All the SusInkCoat partners will also work with academic researchers at several Dutch universities in an effort to identify promising developments that can be commercialized, used for education purposes or for outreach to the public.

Research being conducted by the other six consortia includes investigating methods to make tastier plant-based food; flat optics for more sustainable hi-tech equipment; and cheaper and more accessible medical imaging technology.

Refashion, a textile industry’s eco-organisation, has renewed its authority approval until 2028. 6 years during which it will continue to transform the industry in keeping with the objectives set by the French Ministry of Ecological Transition and the French Ministry of the Economy, including the objective to collect 60% of CHF (clothing, household linen and footwear textiles) placed on the market by 2028. This new period is reflected in an ambitious road map and significantly increased investment. Nearly 1.2 billion euros, financed by the marketers, will be spent on transforming the industry during this new period of authority approval.

Determined to achieve the objectives set out in the ambitious specifications set down by the Secretary of State at the Ministry of Ecological Transition, Berangère Couillard, Refashion has worked on a road map with all of its stakeholders involved in the transformation that is underway. Maud Hardy, nominated as the eco-organisation’s CEO in January 2022, started a collaborative working method that will continue throughout this new period to support areas that are key in this transformation. In the next few months, projects will begin and will visibly highlight the progress made in the three phases of a product’s life cycle: production consumption, regeneration.

Production

• Recognising eco-design initiatives through the eco-modulation of the fees paid by marketers (durability, environmental information labelling, integration of recycled materials). For marketers, these initiatives should represent the scheme’s cornerstone. The aim is to involve all stakeholders in reducing the environmental impact of products.

Consumption

• As from 2023, Refashion will spend 5 million euros minimum per year in awareness-raising activities and on information to the general public by supporting an array of local authority initiatives.
• The launch of a repair fund in 2023, in particular to prolong the usage of textiles and footwear products. More than 150 million euros will be invested between 2023 and 2028 to change the habits of the French population to increase repairs by 35% (guideline target by the ADEME 2019).

Regeneration

• Accelerating clothing, household linen and footwear collection, in particular thanks to an operational mix in the sector. Funding traditional sorting operators will remain central, but Refashion will also develop an additional operational system in order to achieve the collection target of 60% of products placed onto the market (versus 34% in 2021).
• 5% of fees paid to Refashion will go towards the redeployment/reuse funds to provide support for reuse within the remit of stakeholders in the Social and Solidarity Economy. In addition to this funding, additional funding arrangements open to all stakeholders will be established. The total budget throughout the authority approval period represents 135 million euros.
• 5% of fees, i.e., 58 million euros in 6 years, will be spent on R&D to help achieve these milestones in order to industrialise the recycling of used CHF: recyclability that is considered during the design stage; automated sorting and recycling.

A lot of waste is generated in the trade fair and event industry. It makes sense to have furniture that can quickly be dismantled and stored to save space - or simply disposed of and recycled. Paper is the ideal raw material here: locally available and renewable. It also has an established recycling process. The German Institutes of Textile and Fiber Research (DITF) and their project partners have jointly developed a recycling-friendly modular system for trade fair furniture. The "PapierEvents" project was funded by the German Federal Environmental Foundation (DBU).

Once the paper has been brought into yarn form, it can be processed into a wide variety of basic elements using the structure winding process, creating a completely new design language.

The unusual look is created in the structure winding process. In this technology developed at the DITF, the yarn is deposited precisely on a rotating mandrel. This enables high process speeds and a high degree of automation. After the winding process, the individual yarns are fixed, creating a self-supporting component. A starch-based adhesive, which is also made from renewable and degradable raw materials, was used in the project for the fixation.

The recyclability of all the basic elements developed in the project was investigated and confirmed. For this purpose the research colleagues at the project partner from the Department of Paper Production and Mechanical Process Engineering at TU Darmstadt (PMV) used the CEPI method, a new standard test procedure from the Confederation of European Paper Industries.

Sensor and lighting functions were also implemented in a recycling-friendly manner. The paper sensor yarns are integrated into the components and detect contact.

Also, a modular system for trade fair and event furniture was developed. The furniture is lightweight and modular. For example, the total weight of the counter shown is well under ten kilograms and individual parts can easily be shipped in standard packages. All parts can be used several times, making them suitable for campaigns lasting several weeks.

A counter, a customer stopper in DIN A1 format and a pyramid-shaped stand were used as demonstrators. The research work of the DITF (textile technology) and PMV (paper processing) was supplemented by other partners: GarnTec GmbH developed the paper yarns used, the industrial designers from quintessence design provided important suggestions for the visual and functional design of the elements and connectors and the event agency Rödig GmbH evaluated the ideas and concepts in terms of usability in practical use.

Celanese Corporation, a specialty materials and chemical company, and Under Armour, Inc., a company in athletic apparel and footwear, have collaborated to develop a new fiber for performance stretch fabrics called NEOLAST™. The innovative material will offer the apparel industry a high-performing alternative to elastane – an elastic fiber that gives apparel stretch, commonly called spandex. This new alternative could unlock the potential for end users to recycle performance stretch fabrics, a legacy aspect that has yet to be solved in the pursuit of circular manufacturing with respect to stretch fabrics.

NEOLAST™ fibers feature the powerful stretch, durability, comfort, and improved wicking expected from elite performance fabrics yet are also designed to begin addressing sustainability challenges associated with elastane, including recyclability. The fibers are produced using a proprietary solvent-free melt-extrusion process, eliminating potentially hazardous chemicals typically used to create stretch fabrics made with elastane.

NEOLAST™ fibers will be produced using recyclable elastoester polymers. As end users transition to a more circular economy, Celanese and Under Armour are exploring the potential of the fibers to improve the compatibility of stretch fabrics with future recycling systems and infrastructure.

In addition to the sustainability benefits, the new NEOLAST™ fibers deliver increased production precision, allowing spinners to dial power-stretch levels up or down and engineer fibers to meet a broader array of fabric specifications.

Fashion for Good's Sorting for Circularity framework expands to address the challenge of ensuring rewearable textiles remain in use as opposed to finding their way into global waste streams or landfills. This 18-month project tests automated sorting technologies using artificial intelligence and machine learning to optimise the sorting of rewearable garments and enable greater circularity.

This project will test automated sorting technologies using machine learning and artificial intelligence (AI) to collect product information — such as colour, style, garment type, and quality. This will enable sorters and brands to make better decisions and sort efficiently based on product data and criteria from local, European, and export resale market requirements, thus optimising the flow of textiles to achieve their highest value potential.

To ensure accuracy and representation in capturing data on the flow of textiles within the EU and export markets, this project will focus on specific geographical regions: Lithuania (Nordic/Baltic), the Netherlands (Western), Poland (Central-Eastern), and Spain (Southern Europe).

The findings will be shared in a report with a supporting business case and implementation roadmap to inform investment decisions in infrastructure, Circular Business Models (CBM) and repair centres.

The Rewear Project builds on Fashion for Good’s Sorting for Circularity framework initiated in 2021 and subsequently launched in Europe, India and the United States harmonising the collection, sorting and recycling industries in order to advance textile-to-textile recycling technologies and the resale industry.

It is funded by brand partners adidas, BESTSELLER, Bonprix, C&A, Inditex, Levi Strauss & Co., Otto Group, PVH Corp., and Zalando. Circle Economy Foundation leads the creation and implementation of the methodology, with support from Consumption Research Norway, Oslo Metropolitan University and Revaluate.

The Lenzing Group has once again been recognized for its sustainability performance and its active contribution to transforming the industry towards a circular economy. The rating agency MSCI awarded Lenzing an “AA” rating for the third time in a row, placing Lenzing among the top eight percent of rated companies in its peer group. In addition, Lenzing participated for the first time in the SAC Higgs FEM verification to assess the environmental impact of product manufacturing at its sites and achieved positive results.

According to the rating agency MSCI, Lenzing continues to lead the way among global companies in terms of governance structures. In addition, MSCI highlights Lenzing’s leadership in implementing initiatives to mitigate the risk of environmental liabilities associated with the release of toxic pollutants and highlights its water stewardship program, which includes a water risk assessment. The confirmation of the “AA” rating from MSCI ESG enables Lenzing to further reduce its interest expense. In November 2019, Lenzing placed a bonded loan in the amount of around EUR 500 mn, which is linked to the company's sustainability performance. In line with its commitment under the bonded loan, the company will donate the entire interest expense it saves thanks to the “AA” rating to a social-ecological project.

By November 2023, all Lenzing sites, with the exception of the sites in Brazil and Thailand, which are however scheduled for 2024, have completed the first external verification of the module with excellent results. With almost 20,000 participating companies from different sectors of industry, which achieved less than 50 percent in total average in 2023, Lenzing sites achieved verified scores of more than 70 percent to 95 percent.
