For the third time, nova-Institute awards the “Cellulose Fibre Innovation of the Year” award in the frame of the “Cellulose Fibres Conference 2023” (8-9 March 2023). The conference advisory board nominated six remarkable products, including cellulose fibres from textile waste, banana production waste and bacterial pulp, a novel technology for producing lyocell yarns and a hygiene product. The innovations will be put to the vote of the conference audience on the first day of the event, with the awards ceremony taking place in the evening. The innovation award “Cellulose Fibre Innovation of the Year 2023” is sponsored by GIG Karasek (AT).

Here are the six nominees
Vybrana – The new generation banana fibre – GenCrest Bioproducts (India)
Vybrana is a Gencrest’s Sustainable Cellulosic Fibre upcycled from agrowaste. Raw fibres are extracted from the Banana Pseudo stem at the end of the plant lifecycle. The biomass waste is then treated by the Gencrest patented Fiberzyme technology. Here, cocktail enzyme formulations remove the high lignin content and other impurities and help fibre fibrillation. The company's proprietary cottonisation process provides fine, spinnable cellulose staple fibres suitable for blending with other staple fibres and can be spun on any conventional spinning systems giving yarns sustainable apparel. Vybrana is produced without the use of heavy chemicals and minimized water consumption and in a waste-free process where balance biomass is converted to bio stimulants Agrosatva and Bio Fertilizers & organic manure.

HeiQ AeoniQ™ – technology for more sustainability of textiles – HeiQ (Austria)
HeiQ AeoniQ™ is the disruptive technology and key initiative from HeiQ with the potential to change the sustainability of textiles. It is the first climate-positive continuous cellulose filament yarn, made in a proprietary manufacturing process and the first to reproduce the properties of polyester and nylon yarns in a cellulosic, biodegradable, and endlessly recyclable fibre.
HeiQ AeoniQ™ can be manufactured from different cellulosic raw materials such as pre- and post-consumer textile waste, biotech cellulose, and non-valorized agricultural waste, such as ground coffee waste or banana peels. It naturally degrades after only 12 weeks in the soil. Each ton of HeiQ AeoniQ™ saves 5 tons of CO2 emissions. The first garments made with this innovative cellulosic filament fiber were commercially launched in January 2023.

TENCEL™ LUXE – lyocell filament yarn – Lenzing (Austria)
TENCEL™ LUXE is LENZING’s new versatile lyocell yarn that offers an urgently needed sustainable filament solution for the textile and fashion industry. A possible botanical alternative for silk, long-staple cotton, and petrol-based synthetic filaments, is derived from wood grown in renewable, sustainably managed forests, and produced in an environmentally sound, closed-loop process that recycles water and reuses more than 99 % of organic solvent. Certified by The Vegan Society, it is suitable for a wide range of applications and fabric developments, from finer high fashion propositions to denim constructions, seamless and activewear innovations, and even agricultural and technical solutions.

Nullarbor™ – Nanollose & Birla Cellulose (Australia/India)
In 2020, Nanollose & Birla Cellulose started a journey to develop and commercialize tree-free lyocell from bacterial cellulose, called Nullarbor™. The name derives from the Latin “nulla arbor” which means “no trees”. Initial lab research at both ends led to a joint patent application with the patent “production of high-tenacity lyocell fibres made from bacterial cellulose”.
Nullarbor is significantly stronger than lyocell made from wood-based pulp; even adding small amounts of bacterial cellulose to wood pulp increases the fibre toughness. In 2022, the first pilot batch of 260kg was produced with 20 % bacterial pulp share. Several high-quality fabrics and garments were produced with this fibre. The collaboration between Nanollose & Birla Cellulose now focuses on increasing the production scale and amount of bacterial pulp in the fibre.

Circulose® – makes fashion circular – Renewcell (Sweden)
Circulose® made by Renewcell is a branded dissolving pulp made from 100 % textile waste, like worn-out clothes and production scraps. It provides a unique material for fashion that is 100 % recycled, recyclable, biodegradable, and of virgin-equivalent quality. It is used by fibre producers to make staple fibre or filaments like viscose, lyocell, modal, acetate or other types of man-made cellulosic fibres. In 2022, Renewcell, opened the world’s first textile-to-textile chemical recycling plant in Sundsvall, Sweden – Renewcell 1. The plant will eventually reach 120,000 tons of annual capacity.

Sparkle sustainable sanitary pads – Sparkle Innovations (United States)
Globally, around 300 billion period products are discarded every year, resulting in millions of tons of non-biodegradable waste. Since most conventional sanitary pads contain up to 90 % plastics, they do not biodegrade for around 600 years. Sparkle has designed sustainable, plastic-free, biodegradable and compostable Sparkle sanitary pads. From product to packaging, they are made up of around 90 % cellulose-based materials with top sheet, absorbent core, release paper, wrapping paper and packaging made of cellulose-based fibres. Whether Sparkle pads end up in a compost pit, are incinerated or end up in a landfill, they are a more sustainable alternative compared to conventional pads that contain large amounts of plastics, complex petro-chemical based ingredients and artificial fragrances. When tested according to ISO 14855-1 by a leading independent lab in Europe, Sparkle pads reached over 90 % absolute biodegradation within 90 days in commercial composting conditions.

The viscose fibre manufacturer Kelheim Fibres - exclusively using FSC® or PEFCTM certified pulps exclusively from sustainably managed sources - welcomes the preliminary political agreement reached between the European Parliament and the Council on an EU regulation on deforestation-free supply chains. The new rules, adopted at the end of 2022, are intended to prevent goods that cause forest degradation or deforestation from being placed on the EU market.

As one of the largest economies worldwide, the EU is a major consumer of wood-based raw materials. Therefore, the new law can significantly contribute to reducing global deforestation and forest degradation as well as protecting threatened forest areas.

“Wood is an incredibly versatile and valuable renewable resource and the basis for countless products. Our viscose fibres are just one example – they offer an environmentally friendly alternative to synthetic materials in various applications and are thus a promising material for the future. Of course, this only applies if the production of our raw materials does not take place at the expense of our earth's natural forest resources. These forests are a bastion of biodiversity and climate protection for our entire planet and must be protected at all costs. No one can escape this responsibility," says Craig Barker, CEO at Kelheim Fibres.

Carbios and Novozymes announced an exclusive long-term global strategic partnership. This major agreement ensures the long-term production and supply of Carbios’ proprietary PET-degrading enzymes at an industrial scale for the world’s first biological PET-recycling plant due to start production in 2025 in Longlaville (France), as well as Carbios’ future licensee customers.
 
Carbios and Novozymes have had a partnership since 2019 to develop enzyme-based solutions and address  the sustainability challenge of plastic pollution, both within PET-recycling[1] and PLA-biodegradation[2].  Building on the current Joint Development Agreement (JDA), under the new agreement, Carbios and Novozymes will extend their collaboration to develop, optimize and produce enzymes that will subsequently be supplied by Novozymes to all licensees of Carbios’ technology.  The new agreement grants both parties exclusivity in the field of the partnership.
 
The strategic partnership supports the large-scale industrial deployment of Carbios’ patented PET-recycling technology starting with Carbios’ future industrial reference unit in Longlaville (France), which will be the world’s first biological PET-recycling plant. Construction will begin later this year, and both building and operating permits having been filed with local authorities.  Production at the plant is set to start in 2025 and the processing capacity will be 50,000 tonnes of waste per year.

Haelixa, the Swiss traceability company and Damteks Textiles have announced a collaboration to mark and trace recycled acrylic fiber. Damteks is offering their recycled yarn to customers whereby they are able to place an order with the unique Haelixa DNA already attached.

The Haelixa solution is DNA markers which are solved in liquid and applied to fibers as a fine spray. Spot checks are completed after spraying to determine the presence of DNA and identify the product. The test is based on PCR technology that is 100% reliable and has forensic validity.

Damteks saw an increase in demand for blended yarn in the last year. The request is most often a composition of 30% recycled fiber with 70% standard fiber. Brands are looking for options to be more sustainable and Damteks proactively sought out an answer. They are offering the yarn with Haelixa DNA to validate the recycled acrylic in the mix.

The haelixa team visited the Damteks recycling facility in Istanbul to kick off the partnership that will continue throughout 2023. The traceability program has the DNA sprayed on the recycled fibers before spinning. The project also saw the use of a tailored Haelixa liquid sprayer designed by the team based in Switzerland. When manufacturers do not have built-in moisturizing systems, Haelixa provides them with a custom unit to shower the DNA liquid onto the fibers. This sprayer is engineered to match the mechanical processing of the customer.

Damteks is a family-owned business that pride itself in carefully selecting environmentally responsible options for its production processes. On top of the certifications they have obtained including - GRS, RCS, GOTS, OCS - Damteks decided to have their products "Marked and Traced by Haelixa" to add additional credibility and reliability. Damteks plans to offer marked and traced by Haelixa yarn in different dyes as their offering to brands.

In occasion of the next edition of Pitti Uomo, Bemberg™ by Asahi Kasei – the unique fiber with a circular economy footprint obtained from cotton linters through a closed-loop process ensuring certified sustainability credentials through its transparent and traceable approach- reveals a very special Bemberg™ fabrics smart range dedicated to premium denimwear.

This has been made possible thanks to the partnership with PureDenim, a leading Italian company whose strategy since 10 years is based on an entire re-design of the production system, inspired by circular economy principles that combines technology and innovative materials in order to offer the highest levels of design, innovation and real responsible values derived from an holistic approach to sustainability.
The “Blue di Cupro” collection is made with seven fabrics made with Bemberg™, either 100% Bemberg™ or in blend with cotton, wool, and it applies the most advanced Pure Denim Technologies. The Blue di cupro fabrics made with Bemberg™ will also be dyed with “Smart Indigo” an indigo dye technology internally produced by PureDenim, through a chemical-free production. The only elements involved are: water, indigo pigments, and electricity. In terms of finishing, fabrics’ looks and performances are enhanced by the “Eco Sonic” ultrasounds finishing technology which brings significant reduction of water used, increased aesthetic features and controlled discoloration. And last but not least every yarn used at PureDenim is protected by NaturalReco® a 100% natural product that completely SUBSTITUTE the use of plastic films that are one of the key causes of microplastic emission for denim application.

“Blue” seems to be the new colour of Bemberg™, in fact, the company in early November 2022 announced, at the Blue Friday initiative by UNESCO's Intergovernmental Oceanographic Commission (IOC), the achievement of the OK biodegradable MARINE certification, which guarantees the biodegradability of its products even in the marine environment, as certified by TÜV AUSTRIA, meaning a lot in the context of microplastics in water issue solutions. This Bemberg™ certification’s achievement comes on top of other key ones such as the INNOVHUB report that confirms Bemberg™ biodegradability in soil without releasing hazardous substances, the RCS by Textile Exchange, and the Oeko-Tex Standard 100 and ISO 14001 corporate certifications.

In view of the easing of pandemic restriction policies in China, the Spring Editions of Intertextile Shanghai Apparel Fabrics, Yarn Expo and Intertextile Shanghai Home Textiles have been moved to the new timeslot of 28 – 30 March 2023. This will allow both local and international fairgoers more time to prepare for their participation, with a higher industry turnout now expected at the three fairs. The fairs will still be located at the National Exhibition and Convention Center in Shanghai where they were originally due to be held from 8 – 10 March.

Discussing the change of dates, Ms Wilmet Shea, Deputy General Manager of Messe Frankfurt (HK) Ltd explained: “After talking to our stakeholders, we believe adjusting the spring show dates to the end of March is the right move. It provides enough time for exhibitors and visitors from local and abroad to plan for the fairs and capitalise on the ample international business opportunities brought by the reopening of China’s border.”

Fibres, fabrics, epoxy resins and adhesives from Sicomin have been used by Grand Largue Composites (GLC) to construct the first Class40 racing yacht to feature a significant quantity of flax-fibre reinforcements.
The yacht, called Crosscall, won the Class40 World Championships in June 2022 and is a prototype of the new Lift V2 design by Marc Lombard, one of the leading naval architects in this field.

Class40 is one of the most competitive fleets in yacht racing. The hulls of Class40 yachts must be light in weight, strong and stiff, and durable in the most extreme of conditions. Furthermore, to keep costs down, they cannot be reinforced with carbon fibres. The quality and reliability of the resins used for the infusion and lamination of the hulls are therefore of paramount importance.

Crosscall's cockpit was designed to be effectively non-structural, with the mainsheet, which can generate huge shock loads, supported separately. This would allow the cockpit to be made from a hybrid biaxial fabric comprising 50% flax fibres. Other parts of the boat that incorporate flax fibre include the tunnel, the engine cover, the ballast tanks and the cap. The rest of the boat is reinforced with 100% glass-fibre fabrics.

To help it realise this ambitious design, GLC, an infusion specialist, turned to its long-time material supplier, Sicomin. The hull was moulded and infused in one piece and the deck – including the hybrid flax-fibre cockpit – was also infused as a single part. The internal structure was then laminated into the hull by hand before the hull and deck were finally bonded together.

The infusion resin selected was Sicomin’s SR 1710, a high-modulus structural epoxy. Designed specifically for use in infusion and injection processes, it has exceptionally low viscosity and its low-reactivity hardener makes it suitable for the production of large parts. Composites components made from SR 1710 possess high interlaminar shear-strength and the resin retains its mechanical properties in wet environments.

Sicomin’s low-toxicity SR 8200 was used to laminate the internal structures onto the skin of the hull. Ideal for hand laminating, this system includes a choice of hardeners with a wide range of reactivities, which makes it equally suitable for making large or small parts. The hull and deck were joined together with Sicomin’s Isobond SR 7100, which demonstrates high fatigue strength and is very resistant to microcracking.

An epoxy bonding primer – called Undercoat EP 215 HB+ and supplied by Sicomin’s sister company, Map Yachting – was applied to the moulds first to make demoulding easier. It also serves as an undercoat in the polyurethane exterior paint system that is used instead of gelcoat to protect the epoxy hull from UV damage.

Since the launch of Crosscall, GLC has started building a second Lift V2 Class40 and a third one is now planned, both for which Sicomin will supply the materials.

• made out of recycled PET flakes and recyclable again
• suited for finishing recycled yarns and fabrics
• moisture management in sports and active wear

For the sustainable use of resources, the CHT Group has developed the product ARRISTAN rAIR, according to the principles of the circular economy. Here, plastic waste is converted into a valuable textile finishing product to achieve, for example, optimal moisture management in sports and active wear. Other areas of application include socks and tights in the clothing sector, filtration media and nonwovens in the technical textiles sector, and pillows and curtains in home textiles.

Since ARRISTAN rAIR is made out of recycled PET flakes, it is suited for finishing recycled yarns and fabrics which are subsequently recyclable again.

The hydrophilizing agent ARRISTAN rAIR is characterized by its fast-drying properties in combination with excellent soil release and thermoregulation. It therefore offers, especially in the field of functional textiles, optimal functionalities for high-quality and durable sportswear.
