From the Sector

As one of the driving forces helping to create a fully circular fashion industry, ISKO has partnered with Swedish research and development company MoRe Research, a part of RISE Research Institutes of Sweden, to investigate and develop new, sustainable technologies made from cellulosic-based materials, derived from waste textiles, for the company’s 25,000+ range of products. It is hoped that this research will also help make the production of cellulose-based materials more sustainable.

The work with MoRe Research feeds into ISKO’s Responsible Innovation™ strategy and will link with various sustainability projects the company is working on. For example, ISKO recently signed an agreement with HKRITA to license its Green Machine – a unique technology that fully separates and recycles cotton and polyester blends at scale.

ISKO will leverage MoRe Research!s expertise and resources to find ways of repurposing the clean and toxic-free cellulose powders that are created from the decomposed cotton, as well as the recycled polyester and reintegrate this back into fabric production. By using all of the outputs from the recycling of textiles back into textiles, the prospect of a closed-loop system becomes more feasible.

The investment in this new technology is the latest in ISKO’s ongoing drive for advancements in sustainability. As part of the company’s R-TWO™ program ISKO is also working to develop fabrics with a guaranteed minimum +50% GRS (Global Recycle Standard) recycled content blend. This will significantly reduce the carbon and water footprint of a fabric, as well as make it easy to trace a garment’s sustainable journey step-by-step from the beginning of the supply chain through to the end product.

• Long-term partnership between the Austrian textile producer FEINJERSEY and the German textile machinery manufacturer BRÜCKNER

The Feinjersey Group is an internationally operating textile company and supplies the "global players" of the textile industry worldwide. The value chain of the company, which is based in Götzis, Austria, ranges from yarn processing to the finished product.

As a fully integrated production company, the internationally active textile company Feinjersey attaches great importance to a high quality standard and guarantees care at every step in the process chain. With approx. 250 employees and annual sales of around 45 million euros, the company knits, dyes and finishes top-quality knitted fabrics as well as elastic woven fabrics for a wide range of applications.

Products are made for the fashion, sports, workwear and technical textiles sectors. Among other things, fabrics for the automotive industry, laminating backings and coating substrate for artificial leather or foils, construction textiles or fabrics for medical technology are all produced.

The Austrian textile manufacturer has been certified with the Bluesign textile seal and ensures efficient use of resources with modern machinery. Water and energy consumption as well as pollutant emissions are to be reduced to a minimum.

In textile finishing in particular, the focus is on minimising energy consumption as this process is the most energy-intensive in the entire process chain. Feinjersey uses its own photovoltaic system for this purpose, as well as the heat recovery and exhaust air purification systems on the stenter frames. By using the waste heat from production, the company's buildings are heated. All six stenter frames at Feinjersey are made by BRÜCKNER and produce with three-stage heat recovery and exhaust air purification systems.

The latest BRÜCKNER line has a working width of 4.20 m and is mainly used for the finishing of high-ly elastic and extremely sensitive knitted fabric. In order to avoid yellowing on the fabric, the stenter is equipped with an indirect gas heating system. The knitting oil vapours coming from the fabric during the heat-setting process are extracted from the dryer and cleaned in a BRÜCK-NER ECO-AIR exhaust air cleaning system before being extracted to atmosphere. The complete exhaust air treat-ment on the newest stenter is carried out by a multistage BRÜCKNER ECO-HEAT and ECO-AIR system.

There has been a sharp rise in demand for organic cotton products. Compared to conventionally grown cotton, the cultivation of organic cotton requires the renunciation of genetically modified seeds, chemical pesticides or fertilisers. Nevertheless, genetic modifications are repeatedly found in textiles that are falsely labelled with organic claims. Often, available certification systems are not backed up by lab testing. At best, they only take random seed samples. Textile testing specialist, Hohenstein, has developed an assessment method specifically for cotton. This new DNA analysis method makes it possible to ascertain the amount of genetically modified cotton contained in products. This is good news for textile industry stakeholders who will be on the safe side in terms of quality control and labelling of organic cotton products.

First step: qualitative screening and identification. Second step: quantification of genetically modified cotton.
For qualitative screening, Hohenstein experts had developed molecular biological detection systems to make clear yes/no statements about genetically modified cotton. Testing can be applied to all kinds of materials, from raw cotton to chemically untreated yarns and fabrics. In addition, Hohenstein is one of only a few laboratories in the world accredited to test for GMOs in accordance with the ISO/IWA 32:2019 protocol. Its method provides reliable evidence of the presence or exclusion of genetic modification in cotton textile precursors.

Once qualitative proof of genetic modification is obtained, Hohenstein experts begin quantifying the type and extent of the genetic modifications. To do this, they use DNA analysis to search for different cotton lines known to contain genetic alterations and quantify the proportion. Only by pinpointing individual genetic modifications and quantifying the extent of modification is it possible to provide precise information on whether there is an extremely small proportion of contamination, or whether larger proportions of GMOs have been mixed in. This offers clear benefits to manufacturers, brand owners and retailers when it comes to supply chain transparency and fraud prevention.

International technology Group ANDRITZ has received an order from Renaissance Textile to deliver a recycling line for their first recycling platform, located in Laval, France. Start-up of the recycling line from ANDRITZ Laroche is scheduled for the end of Q2 2022.

First of all, postconsumer waste fibers will be opened, then mixed with virgin fibers and spun once again in order to ultimately produce new textiles. The specific design of this line is the outcome of close collaboration between experts from ANDRITZ Laroche and the customer, with customized trials being conducted at the ANDRITZ technical center in Cours, France.

Renaissance Textile’s target is to become the first French recycling platform dedicated to end-of-life
textiles, and the company will soon open the new 12,000 sqm plant.

ISKO, a global, leading premium denim ingredient brand, announced its participation in The Jeans Redesign – a project, established by the Ellen MacArthur Foundation’s Make Fashion Circular initiative, to encourage and guide the denim industry to transform the way jeans are made and move towards a circular economy for fashion.

ISKO meets the requirements for participation set by The Jeans Redesign guidelines and has made a commitment that 85% of its entire fabric production will consist of recycled material content made from pre-consumer and post-consumer recycled materials. This production will be independently verified by Textile Exchange audit bodies.

This achievement is made possible using ISKO’s R-TWO™ technology which is created through a patented and exclusive yarn spinning technique that retains the unique properties and benefits found in ISKO’s statement fabrics. ISKO’s R-TWO™ is the embodiment of its Responsible Innovation™ mindset and aligns with the principles of a circular economy espoused by the Ellen MacArthur Foundation – to ensure durability, material health, recyclability and traceability. R-TWO™ positions ISKO as a sustainability leader and enables it to exceed the project guidelines to create denim that is designed to be used more, made to be made again and made from safe and recycled or renewable inputs.

Truetzschler Nonwovens will deliver equipment to enlarge an existing spunlacing line - put into operation in 2015 at the Turkish Eruslu Nonwovens Group - into a flexible, state-of-the-art production line for various light to heavy weight sustainable nonwovens.

Last year Eruslu decided to broaden its portfolio in the wipes segment by adding biodegradable products from renewable resources. The group took full advantage of the 2015 small capacity line and went for:

• a second NCR random and a NCA airlay card
• fiber preparation and card feeding equipment for the two new cards
• more hydraulic power to reliably and efficiently hydroentangle multi-layer webs
• an extension to the dryer for increased evaporation capacity

After starting up in the second half of 2022, Eruslu will be operating an ultra-modern, highly flexible NCR-NCA-NCR spunlace line, the first of its kind in Turkey. The line is tailor-made to process virgin cotton fibers, comber noils and short fibers at high speeds. End products are top-quality, lightweight natural wipes or heavy-weight, three-layer nonwovens for cosmetic pads.

Iluna Group comes back to Milano Unica with a great and important goal: to relaunch the qualities and dimensions of sustainability by going beyond the ingredient.

Iluna’s new path, which was born in a moment when the market seems to speak about “fragility”, begins with the investment in the renewal of machines, which allow it to fly ever higher in terms of high-tech developments, quality, definition, effects of yarns and patterns. The journey into the new dimension of responsible quality continues with ad hoc developments in the field of GRS (Global Recycled Standard) certified recycled yarns, aimed at unprecedented effects both in look, in performance and in the hands of fabrics. Including cord yarn, shiny threads and an expansion of the range of GRS yarns, previously available only opaque. The cord yarn is a precious yarn with a ROICA™ EF premium stretch yarn core, GRS certified and developed with 50% of pre-consumer waste materials content - double, covered with an equally recycled shiny thread; the bright and translucent is instead to add brilliant effects so far not possible with a GRS yarn.

The printing processes are also born from this constant search for innovation towards new materials and new techniques, becoming more and more sustainable: Global Recycle Standard (GRS)-certified sublimation printing and register printing carrying Global Organic Textile Standard (GOTS) certification. This one overlap exactly on the design and color the details, reaching where the dye cannot reach.

Diversification has become essential in today’s competitive market and the fragility of the moments experienced in 2020 was the stimulus to return to being here again, to return to action. Flexibility is the watchword today, along with research. And Iluna has managed to go further: starting from the ingredients at the base of the materials, last year launched a collection with natural dyes made with GOTS certified plant-based dyes, up to proposing magnificent prints with extraordinary effects for this edition of the Milanese fair.

The three dimensions of sustainability, design and innovation are thus finally linked thanks to valuable partnerships with expert and excellent reference companies that have allowed these new developments and these unique results thanks to advanced technologies designed specifically for Iluna, which is today the only company to offer ingredients, natural colors and prints, all three strictly certified.

• Fraunhofer, SABIC, and Procter & Gamble join forces
• The Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE and its Institute for Environmental, Safety and Energy Technology UMSICHT have developed an advanced recycling process for used plastics.
• The pilot project with SABIC and Procter & Gamble serves to demonstrate the feasibility of closed-loop recycling for single-use facemasks.

Due to COVID-19, use of billions of disposable facemasks is raising environmental concerns especially when they are thoughtlessly discarded in public spaces, including - parks, open-air venues and beaches. Apart from the challenge of dealing with such huge volumes of essential personal healthcare items in a sustainable way, simply throwing the used masks away for disposal on landfill sites or in incineration plants represents a loss of valuable feedstock for new material.

“Recognizing the challenge, we set out to explore how used facemasks could potentially be returned into the value chain of new facemask production”, says Dr. Peter Dziezok, Director R&D Open Innovation at P&G. “But creating a true circular solution from both a sustainable and an economically feasible perspective takes partners. Therefore, we teamed up with Fraunhofer CCPE and Fraunhofer UMSICHT’s expert scientists and SABIC’s Technology & Innovation specialists to investigate potential solutions.”

As part of the pilot, P&G collected used facemasks worn by employees or given to visitors at its manufacturing and research sites in Germany. Although those masks are always disposed of responsibly, there was no ideal route in place to recycle them efficiently. To help demonstrate a potential step change in this scenario, special collection bins were set up, and the collected used masks were sent to Fraunhofer for further processing in a dedicated research pyrolysis plant.

“A single-use medical product such as a face mask has high hygiene requirements, both in terms of disposal and production. Mechanical recycling, would have not done the job”, explains Dr. Alexander Hofmann, Head of Department Recycling Management at Fraunhofer UMSICHT. “In our solution, therefore, the masks were first automatically shredded and then thermochemically converted to pyrolysis oil. Pyrolysis breaks the plastic down into molecular fragments under pressure and heat, which will also destroy any residual pollutants or pathogens, such as the Coronavirus. In this way it is possible to produce feedstock for new plastics in virgin quality that can also meet the requirements for medical products”, adds Hofmann, who is also Head of Research Department “Advanced Recycling” at Fraunhofer CCPE.

The pyrolysis oil was then sent to SABIC to be used as feedstock for the production of new PP resin. The resins were produced using the widely recognized principle of mass balance to combine the alternative feedstock with fossil-based feedstock in the production process. Mass balance is considered a crucial bridge between today’s large scale linear economy and the more sustainable circular economy of the future, which today is operated on a smaller scale but is expected to grow quickly.

“The high-quality circular PP polymer obtained in this pilot clearly demonstrates that closed-loop recycling is achievable through active collaboration of players from across the value chain”, emphasizes Mark Vester, Global Circular Economy Leader at SABIC. “The circular material is part of our TRUCIRCLE™ portfolio, aimed at preventing valuable used plastic from becoming waste and at mitigating the depletion of fossil resources.”

Finally, to close the loop, the PP polymer was supplied to P&G, where it was processed into non-woven fibers material. “This pilot project has helped us to assess if the close loop approach could work for hygienic and medical grade plastics”, says Hansjörg Reick, P&G Senior Director Open Innovation. “Of course, further work is needed but the results so far have been very encouraging.”

The entire closed loop pilot project from facemask collection to production was developed and implemented within seven months. The transferability of advanced recycling to other feedstocks and chemical products is being further researched at Fraunhofer CCPE.
