Eastman announces a partnership with Patagonia to address textile waste.

The outdoor apparel company teamed up with Eastman to recycle 8,000 pounds of pre- and post-consumer clothing waste, which Eastman processed through its molecular recycling technology. The process involves breaking down Patagonia’s unusable apparel into molecular building blocks that Eastman can use to make new fibers.

"We know apparel waste is a major problem, and consumers increasingly want better, more sustainable solutions when their most loved clothing reaches the end of its life," said Natalie Banakis, materials innovation engineer for Patagonia.

"Our collaborations show the world what’s possible when it comes to sustainability,” said Carolina Sister Cohn, global marketing lead for Eastman textiles. “We have the technology to make the textiles industry circular, and we know it requires collaboration with innovative brands to make circular fashion possible. This is only the beginning, and we look forward to more collaborations throughout 2024."

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.

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%.

In January 2024, ERCA Textile Chemical Solutions TCS was launched as an independent entity within the ERCA Group.

The decision to make ERCA TCS a separate company stems from the desire to focus exclusively on solutions for the textile industry and to build an agile entity oriented towards responsible research and production, while continuing to leverage a solid productive and financial background from ERCA S.p.A.

ERCA TCS aims to be the unique and innovative point of reference for textile companies in terms of products and services specifically designed for the needs of a sector that is currently facing challenges and opportunities related to sustainability and responsible production.

ERCA TCS bases its activity on the principles of "green chemistry" to offer the textile industry chemical solutions that make concrete the concepts of safety, performance, and circularity. Its flagship product - REVECOL® - is born from critical waste materials (used vegetable oils) and present in abundance, which through a process attentive to environmental compatibility and safety, are transformed into a line of innovative, certified, high-performance chemical auxiliaries usable by the entire textile industry.

ERCA Group has six plants in three macro-regions: Europe, Latin America, and Asia and produces chemical specialties and auxiliaries with an approach of responsible innovation. Its production covers several markets: textile, cosmetics, polyurethanes, concrete. It has a turnover of 150 million euros and employs 350 people worldwide, 100 of whom are in the sole Grassobbio plant.

A collaboration between Deakin University researchers and Australia’s largest commercial linen supplier Simba Global is tackling a critical global issue, the spread of harmful microplastics through our laundry.

Clothing and textiles are estimated to generate up to 35 per cent of the microplastics found in the world’s oceans, making them one of the biggest contributors. But there is still a lot to be learnt about the characteristics of these microplastics and exactly how and why they are generated.

Researchers at the ARC Research Hub for Future Fibres in Deakin’s Institute for Frontier Materials (IFM) have teamed up with Simba Global, a global textile manufacturing and supply company, to better understand the extent and type of microplastics shed when their products are laundered. Simba Global wants to lead the charge to reduce the environmental impact of textiles.

Lead scientist IFM Associate Professor Maryam Naebe said working with an industry partner on the scale of Simba Global meant the research could have a huge real-world impact.

Simba Global is the major linen supplier to Australia’s hospitals, hotels and mining camps, resulting in 950,000 tonnes of textile products – including bedsheets, bath towels, scrubs and much more – going through the commercial laundering process each year. It also supplies international markets in New Zealand, Singapore and the US.

“As part of our research, we will investigate potential solutions including the pre-treatment of textiles to reduce the shedding of microplastics, or even increasing the size of the plastics that break down so they can be better captured and removed by filtration during the laundering process,” Associate Professor Naebe said.

“Microplastics are now ubiquitous in the environment, they’re in the air we breathe, the food we eat and the earth we walk on. The magnitude of the problem is bigger than previously thought.

“Of serious concern is the mounting evidence that microplastics are having a negative impact on human and animal health. There are not just physical, but chemical and biological impacts.”

Associate Professor Naebe’s team have taken the first steps in the project, analysing wastewater samples from commercial laundries with high-powered electron microscopes in their Geelong laboratory, part of the largest fibres and textiles research facility in Australia.

The team recently presented a new scientific paper at the Association of Universities for Textiles (AUTEX) Conference 2023, which started the important process of formally categorising these types of microplastics, as well as developing standard terminology and testing methods.

“Because our understanding of microplastics is still in its infancy, we needed to start right at the beginning,” Associate Professor Naebe said.

“We need to have a standard definition of what is a microplastic. Up to this point that has been lacking, which makes it difficult to compare and incorporate other studies in this area.

“We are now developing a systematic method for sampling and identifying microplastics in laundry wastewater. It has been tricky to measure the different sizes, but this is important information to have. For example, there are studies that suggest some sizes of microplastics are causing more issues in certain animals.

“The next step will be establishing an essential method to prevent the release of microplastics from textile laundering. This may involve a coating on the surface of the textile or better ways to collect the waste during the washing process.”

Simba Global Executive Chair Hiten Somaia said the company had a strong focus on sustainability, driven by the business’ purpose statement.

“We are proud to partner with Deakin University in what is the first significant research into textile microplastic pollution in Australia. What we are most excited about is sharing the results of this research with all other textile markets in Australia – including clothing – and putting an end to microplastic pollution from textiles.”
