From the Sector

Korteks, one of the world’s biggest yarn producers based in Bursa, Turkey, has started the production of recycled polyester filament yarn in its production facility using a Starlinger recycling line.

With the new recycling facility, which comprises a total closed area of 17,000 m² and has a monthly production capacity of 600 tons, Korteks was able to reduce the production waste at its virgin PES yarn site to zero.

The Starlinger recoSTAR universal 165 H-VAC iV+, which is part of Korteks’ 10 million dollars investment in a new polymer recycling facility, took up operation in May 2021. It has a production capacity of 7,200 tons per year and currently processes clean in-house polyester fibers from production scrap together with washed post-consumer PET flakes at a ratio of 50/50. Korteks uses the polyester regranulate at a share of 100 % for its new polyester filament yarn line it is going to market under the name “TAÇ Reborn”. With this investment, the company has made an important step towards establishing a circular economy in the Turkish textile industry.

The Starlinger recycling line is the first of its kind in Turkey and is equipped with special components for filament yarn recycling. A RSC (Rapid Sleeve Changer) candle filter developed by Starlinger ensures finest melt filtration down to 15 μm. It has been specially designed for polyester recycling and reaches an output of 1000 kg/h. For continuous operation the filter elements are changed “on the fly” without interrupting production, which significantly limits melt loss.

The viscoSTAR SSP unit at the end of the recycling process guarantees consistent IV increase according to the first-in-first-out principle. This makes sure that the produced regranulate has the ideal properties required for filament yarn production. The technical configuration of the line does not only allow the processing of a polyester fiber/PET flake mix as input materials, but also 100 % polyester filament scrap or 100 % PET bottle flakes.

Korteks expects the recycling market in general to grow as there is increased acceptance for recycled products in the society, and predicts the need for recycling solutions also for other synthetic and natural fibers.

• New brand Trevira CS eco

After a challenging 2020 for Trevira CS®, a year in which the coronavirus crisis put pressure on the contract market, in particular on the hotel and event sector, and also on the cruise shipping industry, the market is starting to show some signs of improvement. Numerous new developments are seizing upon the trends that have emerged since the crisis began.

Although the coronavirus pandemic had a negative effect on individual business sectors, it also has the potential to open up new market opportunities for flame retardant Trevira CS fabrics in the long run. The increase in people working from home and the longer and more frequent stay within one’s own home have led to a change in perspective in terms of the relevance of interior design. The design of the living space has undergone a revaluation. Sustainability, durability, high quality, and the desire for safe products that contain little to no harmful substances are defining criteria for selecting a new textile interior. The colour range of the new Trevira CS developments is directed specifically towards this trend and often comes across as discreet and close to nature. After Trevira CS products have found their way more and more into private homes, the new Trevira CS collections include numerous attractive textiles not only for the contract sector but also for the residential sector.

In the contract sector, notably in the hotel industry, the trends towards sustainability and quality are likely to continue to grow. Moreover, there is an increase in awareness as far as hygiene requirements are concerned. Textiles that are easy to clean without losing their appearance or their functionality can excel here. Accordingly, products ordinarily used in the healthcare sector might start to be of interest to the hotel and catering industry, public spaces, the transport industry, and to offices. This will apply in particular to areas where there is a regular flow of visitors and where people come into direct contact with fabrics. Antimicrobial textiles provide additional protection in these situations. Besides their flame retardancy, many new Trevira CS products integrate additional functions such as noise or sun protection.

Trevira has launched the Trevira CS eco brand for flame retardant textiles that consist of recycled Trevira products.
The new Trevira CS eco brand unites sustainability and flame retardancy. Trevira offers products for this which have been manufactured through different recycling processes. The flame retardant filament yarns are based on the use of recycled PET bottles (post-consumer recycling). Textiles bearing the Trevira CS eco trademark consist of at least 50% recycled materials.

Trevira uses an agglomeration facility to recycle reusable waste materials from production to manufacture recycled fibres that, after further processing, retain the same quality and performance characteristics as the original products (pre-consumer recycling).

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.

The Swiss group presents three creative inspirations to explore new shapes, colors, materials and define a new offer featuring a variety of solutions and ideas.
A tribute to health and to balance with nature, to the advanced goldsmith craftsmanship and to the effortless sophistication of industrial luxury: the FW 2022-23 collection by Riri Group is a true kaleidoscope of shapes, colors and materials, where three different creative inspirations meet – Biophilic, Stones&Gold and Industrial Luxe – for a high-end line of accessories.

All three paths are the result of state-of-the-art techniques, of an R&D effort and of the renowned expertise of the Swiss group. Part of the offer is also a selection of pieces by Cobrax Metal Hub, among which stand out buckles and locks with peculiar shapes and finishing.

Looking to the new season with a positive and enthusiastic attitude, the Group continues to work towards an increasing sustainability when it comes to products and processes. The collection, in fact, is a further step toward Riri’s path of green responsibility that the company has taken to bring actual improvement in its sustainable performance. This year, Riri Group published its first Sustainability Report, calculated in compliance with Global Reporting Initiative Standard (GRI), and adopted recycled polyester as production standard for zips’ tapes.

Biophilic
A way to honor love for life, this line emphasizes the importance of physical and mental wellbeing, answering the questions raised during the challenges faced in the last year. Balance with nature becomes a concrete product circularity operation resorting to manufacturing processes with a low environmental impact and to organic and biodegradable materials. Among them stands out recycled polyester for zips which is Global Recycled Standard (GRS) certified, Global Organic Textile Standard certified organic cotton and other alternative fibers, such as nettle, a natural resource that is a great alternative to synthetic fibers. Rivets, zips, buttons and metal components are made of stainless steel, which guarantees durability and resistance, 100% recycled copper and aluminum – light, ductile and resistant to oxidation. Among the most interesting solutions are rice peel powder – used on buttons’ overseals – and eco-sustainable thermoplastic polyurethane, obtained from renewable raw sources.

Stones & Gold
Sophistication and advanced craftsmanship mark the pieces of this creative path which, inspired by goldsmith and glyptic craft tradition, reveals a delicate sense of positivity and richness. Gems, lapis lazuli, marble, and mother-of-pearl are protagonists of a refined selection of accessories designed to amaze and catch the eye, resembling actual jewels. Essential the use of gold, especially in its liquid form: dominating zips and buttons’ finishes, this precious and versatile metal becomes a decorative feature on printed tape.

Industrial luxe
The third proposal embodies the unique style and timeless elegance that have always defined Riri’s products, embellishing them with new engineering details which makes them very relevant. The accessories come with golden and black finishes, both glossy and matt, and explore shapes developed to bring life to a range of luxury accessories with a sophisticated industrial aesthetics. A dominating role goes to stainless steel, along with a selection of impactful and elegant tapes which includes jacquard options, for a retro-futuristic look that is revealed also through the use of mechanical elements, such as screws and etched metal sheets, and in the clean and boxy shapes of pullers and buttons.

Royal DSM, a global science-based company in Nutrition, Health and Sustainable Living, and SABIC, a global leader in the chemical industry, announced a collaboration to create recycled-based Dyneema®. Through a joint pilot with multiple CirculariTeam® members, the manufacturing and usage of Dyneema® using mixed plastic waste as feedstock (via mass balance approach) will be successfully demonstrated. It is an important step toward the future goal of fully closing the loop by delivering Dyneema® made from ultra-high molecular weight polyethylene (UHMwPE) waste. This collaboration underlines DSM’s and SABIC’s efforts to accelerate a circular economy for materials.

By working together with members of CirculariTeam®, DSM will produce recycled-based Dyneema® made using SABIC’s certified circular ethylene as a pilot project in both a sailing rope and a pelagic trawl net application. The circular ethylene, from SABIC’s TRUCIRCLE™ portfolio, uses mixed plastic waste as feedstock (mass balance approach), which not only contributes to preventing valuable plastic from becoming waste and the avoidance of carbon emissions compared to incineration, but it will also help preserve fossil resources. These pilots are an important early-stage milestone in the journey toward making fully circular Dyneema® from HMPE post-production and post-consumer waste.

Jon Mitchell, Managing Director at Marlow Ropes: “We’re proud to be one of the first manufacturers to integrate recycled-based Dyneema® within our products and demonstrate the material’s feasibility. By collaborating with materials science pioneers such as DSM and SABIC, we are able to create products that not only deliver superlative functional performance but also have a lower environmental impact. Our products are trialed and tested by professional offshore sailing teams including 11th Hour Racing Team, a proud partner of ours at Marlow, with whom we share a progressive approach to seeking sustainable solutions: no more business as usual."

Klaus Walther, Managing Director at Gleistein: “Warm congratulations to DSM and SABIC for pushing the boundaries of science to deliver a truly unique product. We’re proud that our ropes can be produced from what once was typical household plastic waste. This is an important stepping stone towards becoming circular. It will enable our customer Maritiem BV to further develop high-tech fishing gear whilst contributing to the circular economy. Not to forget Cornelis Vrolijk Fishing Company, who again illustrate their commitment to Corporate Social Responsibility by introducing this concept in fishery.”

Swiss dairy company Emmi is partnering with Borealis and Greiner Packaging to produce iced coffed drinking cups using chemically recycled polypropylene.

The cups are produced by Greiner Packaging and the chemically recycled material comes from Borealis, one of the world’s leading providers of advanced and circular polyolefin solutions based in Vienna, Austria.

Emmi, Switzerland’s largest milk processor is committed to climate protection and the circular economy. The dairy company has the stated goal to make all of its packaging 100% recyclable and is committed to various measures to promote circularity such as packaging that contains at least 30% recyclate by 2027.

From September 2021 Emmi will use at least 100 tonnes of plastic based on the recycled material each year. Chemical recycling renews plastic back to plastic creating recycled materials with a level of purity equivalent to fossil-fuel based PP and hence, fit for protective, food-safe and other demanding applications. In this way, Emmi is utilizing difficult to recycle feedstock preventing plastic waste that would be likely landfilled or incinerated. In the future, depending on the availability of suitable material, the amount of recycled plastic in packaging is to be further increased.

The new technology to recover the polypropylene is currently still in its infancy, where Greiner Packaging and Borealis are leading the way. Only limited quantities of chemically recycled polypropylene are currently available, and Emmi is one of only a few food manufacturers to have secured a share of the chemically recycled polypropylene plastic through its early commitment and long-standing collaboration with the development companies.

The chemically recycled material used for the cups consists entirely and solely of ISCC (International Sustainability & Carbon Certification) material, on a mass balance basis. Mass balance is a methodology that makes it possible to track the amount and sustainability characteristics of circular and/or bio-based content in the value chain and through each step of the process. This provides transparency ultimately also to the consumers, enabling them to know that the product they are buying is based on this renewable material.

• Renewably Sourced Materials to Help Replace Petrochemicals in Apparel for a Healthier Planet

lululemon athletica inc. (NASDAQ:LULU) announced a multi-year collaboration with sustainable materials leader Genomatica to bring renewably-sourced, bio-based materials into lululemon’s products. This represents lululemon’s first-ever equity investment in a sustainable materials company and Genomatica’s largest partnership within the retail industry. Together, the two companies will create a lower-impact, plant-based nylon to replace conventional nylon, which is the largest volume of synthetic material currently used to make lululemon products.

Genomatica uses biotechnology and fermentation to convert plant-based ingredients into widely used chemical building blocks, like those used to make nylon. These building blocks are converted to pellets and yarns, and the companies will be working closely with lululemon’s fabric supply chain to incorporate this material into future products. Through this collaboration, the companies seek to create positive change within the $22B global nylon market by building more sustainable supply chains.  

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.

• Testing and development achieve rigidity and safety milestone

Basaltex, pioneers in innovative uses of basalt fibres, has achieved a significant milestone in developing and testing a new composite material solution comprising fibres of basalt combined with EconCore’s patented honeycomb technology.

This new material development has greatly improved fire resistance and is highly rigid, as well as the usual honeycomb properties of light-weighting.

The company has tested the composite of basalt fibres, a bio resin and rPET honeycomb.

Filaments of only stone fibres are extruded at a temperature of 1450°C, similar to glass but with a number of advantages, not least the absence of boric acid in the process.

Combining this ecological fibre with EconCore’s sustainable technology using rPET, and the bioresin polyfurfuryl alcohol - 100% derived from a waste stream of sugar cane - make this a very sustainable and environmentally friendly product, unlike the majority of thermoset solutions in this type of application.

Railway applications require materials with enhanced fire resistance and the testing has shown that the EconCore-Basaltex solution fits these needs well, at the same time offering the perspective of drastic weight reduction against traditional monolithic GRPs used rather widely in train interiors.

Such sandwich panel could be deployed in applications such as cladding panels, partitions, tables and flooring. The thermoset skin layers give a fast cure at elevated temperature, meaning short cycle time and enabling automated production’.

As well as the railway interior application, this new material combination could be used in any application that requires fire performance combined with a low weight.

Denim manufacturers employing Monforts technologies showcased their latest activities, including sustainable fabric manufacturing, new advances in fibres, dyes and chemicals, as well as process and supply improvements and recycling options, at Première Vision’s Digital Denim Week, held from July 5-9.

The users of Monforts equipment included AGI Denim (Pakistan), Azgard 9 (Pakistan), Berto (Italy), Bossa (Turkey), DNM (Turkey), Kilim (Turkey) and Orta (Turkey).

The new Naveena Denim Mills (Pakistan) Holistic collection, for example, employs a suite of sustainable materials such as organic cotton and post-consumer and post-industrial waste cotton that has been shredded and recycled at its in-house unit in Pakistan.

Supply chain transparency is also becoming increasingly important, and Turkey’s Bossa is now sharing information on its dyes, energy sources and recycled content use with its customers. For organic cotton in particular, Bossa provides QR codes with which brands can identify the names of individual farms and their locations, as well as details such as the origins of specific seeds and the use of irrigation by growers.

Turkey’s Orta’s new Denim Route – inspired by the historical Silk Road for trade between the East and West – is an interactive supplier map detailing the regions from which it sources cotton, dyestuff, chemicals and various fibres to complement its other transparency initiatives.

Meanwhile, a living and breathing piece of clothing that absorbs carbon dioxide while simultaneously producing oxygen was introduced at Digital Denim Week 2021 by Azgard 9 (Pakistan) .
