From the Sector

As part of a broader initiative to reduce environmental impacts and keep ahead of evolving global chemical regulations, Active Apparel Group (AAG), manufacturer of performance apparel for the leisure/lifestyle and active market, is embracing water-based OEKO-TEX 100 Class 1 Standard Printing Inks in their manufacturing process.

Common and inexpensive inks used in the global manufacture of apparel contain a wide range of toxic chemicals, including phthalates, petroleum-based co-solvents, PVC, and other volatile organic compounds. AAG’s initiative to use OEKO-TEX approved, water-based inks creates benefits for factory workers, people living local to these factories, consumers, and everyone downstream.

AAG offers a range of printing methods to address a variety of customer needs, including:  digital printing, screen printing, and heat transfers for on-garment logos and care instructions. OEKO-TEX certified water-based inks are used for all of its digital printing and for the majority of its screen printing. These non-toxic water-based inks offer a socially and environmentally better alternative to the more commonly used Plastisol inks.

Making a sizable environmental impact, the printing service of AAG’s business is significant. Digital printing averages 25,000 meters per month with screen printing averaging 60,000 garments per month.

The use of water-based inks requires a skilled production team and training of employees is ongoing. AAG currently employs 30 people at its printing operations in Ningbo, China.

Freudenberg Performance Materials Apparel Europe (Freudenberg) has reached a further sustainability milestone: The new Freudenberg Apparel Competence Center in Sant’Omero, Italy, successfully completed the 4sustainability® Chemical Management protocol (4s CHEM) recently and reached the Advanced Level. The aim of the protocol is to progressively eliminate toxic and hazardous chemicals and related risks throughout the production process.

Competence center for interlinings
Freudenberg opened its Apparel Competence Center in Sant’Omero in May 2023. The factory in Italy is an innovative competence center that coats and finishes nonwoven, woven and weft interlinings for apparel customers in Europe.
Freudenberg has now taken the next logical step: as part of a comprehensive audit, the Apparel Competence Center has implemented ZDHC guidelines in its production process. To achieve this, Freudenberg called in the experts from Process Factory, a consultancy that specializes in sustainability topics. With their support, Freudenberg’s Sant’Omero site has reached the Advanced level of the 4sustainability® Chemical Management protocol (4s CHEM), in line with the ZDHC Roadmap to Zero Program.
Implementation is controlled annually based on this protocol and offers companies in the fashion industry a degree of reliability. It guarantees structured, fully transparent procedures, regular monitoring, and continuous control of Freudenberg’s production processes.  

ZDHC
By demonstrating its rejection of environmentally harmful chemicals and substances, the Apparel Competence Center shows that Freudenberg gives top priority to taking responsibility for people and the environment.
The aim of the Zero Discharge of Hazardous Chemicals (ZDHC) Foundation and its globally recognized Roadmap to Zero Program is to eliminate the release of toxic chemicals in the textile and fashion industry’s supply chain based on the ZDHC Manufacturing Restricted Substances List (ZDHC MRSL).
By applying the 4s CHEM protocol, the production site in Sant’Omero is sending a clear signal to the fashion industry that Freudenberg products meet the highest quality standards and are also safe and environmentally friendly.

Lightweight design is a key enabler for addressing the energy transition and sustainable economy. Following the liquidation of the state agency Leichtbau BW GmbH, a consortium consisting of the Allianz Faserbasierter Werkstoffe Baden-Württtemberg (AFBW), the Leichtbauzentrum Baden-Württemberg (LBZ e.V. -BW) and Composites United Baden-Württemberg (CU BW) now represents the interests of the lightweight construction community in the State.

The Lightweight Design Agency for Baden-Württemberg is set up for this purpose on behalf of and with the support of the State. The Lightweight Construction Alliance BW is the central point of contact for all players in the field of lightweight construction in the State and acts in their interests at national and international level. Professor Markus Milwich from the German Institutes of Textile and Fiber Research Denkendorf (DITF) represents the agency.

The use of lightweight materials in combination with new production technologies will significantly reduce energy consumption in transportation, the manufacturing industry and the construction sector. Resources can be saved through the use of new materials. As a cross-functional technology, lightweight construction covers entire value chain from production and use to recycling and reuse.

The aim of the state government is to establish Baden-Württemberg as a leading provider of innovative lightweight construction technologies in order to strengthen the local economy and secure high-quality jobs.

Among others, the "Lightweight Construction Alliance Baden-Württemberg" will continue the nationally renowned "Lightweight Construction Day", which acts as an important source of inspiration for a wide range of lightweight construction topics among business and scientific community.

Professor Milwich, an expert with many years of experience and an excellent network beyond the State's borders, has been recruited for this task. In his role, Milwich also represents the state of Baden-Württemberg on the Strategy Advisory Board of the Lightweight Construction Initiative of the Federal Ministry for Economic Affairs and Climate Action, which supports the cross functional-technology and efficient transfer of knowledge between the various nationwide players in lightweight construction and serves as a central point of contact for entrepreneurs nationwide for all relevant questions.

From 2005 to 2020, Professor Milwich headed the Composite Technology research at the DITF, which was integrated into the Competence Center Polymers and Fiber Composites in 2020. He is also an honorary professor at Reutlingen University, where he teaches hybrid materials and composites. "Lightweight design is an essential aspect for sustainability, environmental and resource conservation. I always showcase this in research and teaching and now also as a representative of the lightweight construction community in Baden-Württemberg," emphasizes Professor Milwich.

The EU directive on the further development of sustainability reporting (CSRD) poses major challenges for companies and the public sector. Until now, the regulations have only applied to large capital market-oriented companies. However, far-reaching changes to sustainability reporting are expected when the CSRD is transposed into national law in 2024. The German Institutes of Textile and Fiber Research (DITF) are facing up to this challenge of external reporting and at the same time the responsibility for sustainable and resource-conserving science. The Textile Research Center has therefore set up a specialist department reporting to the Executive Board.

The DITF are reaffirming their commitment to sustainability with the appointment of the previous Head of the Competence Center Textile Chemistry, Environment & Energy, Dr.-Ing. habil. Thomas Stegmaier, as Chief Sustainability Officer (CSO). In addition to this new role, Stegmaier will continue to provide his expertise to the Competence Center Textile Chemistry, Environment & Energy as Deputy Head.

The task of the Chief Sustainability Officer is to develop solutions to reduce the DITF's energy and resource consumption, promote renewable energies and implement efficient energy use. The management team, the operational organizational units and all employees are involved in the process.

The CSO also acts as a driving force for both the Executive Board and the research departments to promote sustainability issues.

Re:NewCell AB announced that the Stockholm District Court has decided to approve the previously communicated bankruptcy application and has declared the company bankrupt.

The appointed bankruptcy trustee is lawyer Lars-Henrik Andersson at Cirio Advokatbyrå.

February,25 the Board of Directors had decided to file for bankruptcy of Re:NewCell AB at the Stockholm District Court. The reason for the decision to file for bankruptcy was that Re:NewCell has not been able to secure sufficient financing to complete the strategic review, announced on 20 November 2023, with satisfactory result.

As part of the strategic review, Re:NewCell has had well advanced negotiations with its two largest shareholders, H&M and Girindus, its existing lenders BNP Paribas, European Investment Bank, Finnvera (as partial guarantor), Nordea, AB Svensk Exportkredit and potential new investors as well as other stakeholders regarding long-term financing solutions. These discussions have not resulted in a solution which would provide Re:NewCell with the necessary liquidity and capital to ensure its operations going forward.

"I regret to inform that we have been forced to take this decision to file for bankruptcy. As we have a strong belief in the company’s long-term potential, we have together with our advisors spent very substantial time and efforts into trying to secure the necessary liquidity, capital and ownership structure for the company to secure its future. As part of the negotiations, we have had intense dialogues with both current main owners, new investors and our banks, as well as other stakeholders. However, these discussions have not been successful. This is a sad day for the environment, our employees, our shareholders, and our other stakeholders, and it is a testament to the lack of leadership and necessary pace of change in the fashion industry” says Chairman of the Board of Directors, Michael Berg.

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.
