From the Sector

Viscose speciality fibre manufacturer Kelheim Fibres, nonwoven producer Sandler, and hygiene product manufacturer pelzGROUP have jointly developed a new panty liner that is plastic-free according to the European Single-Use Plastics Directive (SUPD). This innovative solution is a step towards reducing the amount of plastic in hygiene products – and thus also a contribution to tackling the problem of plastic pollution.

According to a UNEP study on marine litter and microplastics, eight million tons of plastic end up in the oceans every year. A significant portion of this pollution comes from single-use plastic products, including conventional period products such as pads or panty liners.

The partnership between the three companies was formed under the Open Innovation principle, which allowed for creative idea exchange and facilitated the development of an innovative product. According to Jessica Zeitler, R&D Specialist at Sandler, “Our collaboration with Kelheim Fibres and pelzGROUP is a great example of how companies can work together to create solutions that benefit both the environment and consumers. We are proud to be part of this project and the opportunities it offers.”

For hygiene product manufacturer pelzGROUP, it is important to combine sustainability and performance to achieve broad acceptance in the market. “Our panty liner meets the strict requirements of the European Single-Use Plastics Directive (SUPD) while also matching the performance of conventional synthetic products. At the same time, our new panty liner has a completely European supply chain. This means short distances and therefore low CO2 emissions, and – especially in times of global disruption – reliability for our customers,” emphasizes Dr. Henning Röttger, Head of Business Development at pelzGROUP.

"Our viscose speciality fibres are an environmentally friendly and high-performance alternative to synthetic materials," says Dominik Mayer, Project Manager Fibre & Application Development at Kelheim Fibres. "They are at the very beginning of the product value chain and yet have an enormous impact on the functionality of the end product. Open innovation allows us to bring all partners in the value chain to the table, to find the best solution together in a very short time and bring it to commercialisation - the collaboration with Sandler and pelzGROUP is an important milestone in our AHP journey."

Kelheim Fibres, a leading manufacturer of viscose speciality fibres, has joined Recycling Atelier Augsburg. Recycling Atelier Augsburg is a unique centre for research and development in the field of textile recycling. It is located at the Institut für Textiltechnik Augsburg an affiliated institute of Augsburg University of Applied Sciences. The two institutions founded the Recycling Atelier in June 2022 together with twelve partners from the German textile industry.

In the Recycling Atelier, the focus is on the triad of technical and ecological sense as well as economic benefit. In this way, the partners of the Recycling Atelier are standing up against fast fashion, outsourced corporate responsibility and a general decline in raw material quality, which often fuels downcycling - the low-quality reuse - of materials.

As a model factory, the Recycling Atelier Augsburg combines the most important processes of textile recycling and offers holistic and comprehensive research along the value chain," explains Georg Stegschuster, head of the Recycling Atelier Augsburg. The scientists research on all process steps of textile recycling: from material analysis to sorting, preparation and textile processing to sustainable product design. Comprehensive data collection and the use of artificial intelligence as well as innovative materials play a central role.

Kelheim Fibres is a producer of high-quality viscose fibres, which consist of cellulose, the main component of the renewable raw material wood, and are used worldwide for products in areas such as hygiene, textiles, and technical applications.

"In New Business Development as well as Fibre and Application Development, we follow the Open Innovation concept - the cooperation with the Recycling Atelier offers us an ideal platform for this. Here we work with partners to advance sustainability and performance," explains Maik Thiel, project manager at Kelheim Fibres.

Recycled cotton fibres are often very short or of uneven length, which makes further processing of 100 % recycled material a challenge. Adding speciality fibres from Kelheim Fibres should enable the production of high-quality new products, such as nonwovens. In the future, the fibres provided by Kelheim Fibres will also be made from recycled pulp.

The Woolmark Company, the Italian wool fabric mill Vitale Barberis Canonico (VBC) and Haelixa took part in a trial to trace Australian wool fibers up to the final fabric.

Funded by Australian woolgrowers, The Woolmark Company (TWC) is an enterprise that focuses on investments that enhance the profitability, international competitiveness, and sustainability of Australian wool. In their operations, TWC seeks to be transparent and accountable. In line with this strategy, traceability is necessary to ensure transparency and maintain the credibility of TWC.

In December 2021, Haelixa marked wool fibers with their DNA tracing solution. There are infinite DNA markers that could be produced and used to indicate a specific origin, supply chain, material, or particular collection. In this case, a single DNA has been applied to greasy wool and a second DNA marker to scoured wool. The first DNA identifies the origin of the Australian wool, while the second determines the manufacturer where the wool has been further processed; at Vitale Barberis Canonico mill.

Samples were collected from various production stages, where a qPCR test was used to detect each specific DNA marker. Haelixa uses a “Key-Lock” system to detect a marker; one needs to know the particular DNA to screen for, ensuring that the system is tamper-proof. The DNA markers stay safely embedded in the product, enabling traceability of greasy and scoured wool up to greige fabric and finished fabric, respectively.

With increasing cost pressure and competition in the wool fabric market, traceability is becoming a prerequisite to proving authenticity and origin. TWC and Vitale Barberis Canonico support the culture of sustainability and collaboration.

Avgol®, a manufacturer of high-performance nonwoven fabric solutions, will use this month’s FILTECH exhibition in Germany to showcase its latest developments in using Algaeing™’s patented algae bio-based formulations for colorants and fibers.

Together with its sister companies from Indorama Ventures Limited (‘IVL’), Avgol will be presenting biotransformation capable fibers and meltblown for diversified end-use markets at the event from 14-16 February. Avgol will discuss with visitors how this new technology and the company’s biotransformative products can help businesses achieve their 2030 sustainability goals.

Algaeing’s technologies utilize various sustainably sourced, vertically farmed algae species to produce a wide range of appealing colors, many of which replicate the colors used in nonwoven fabrics today.

“The benefits of using an algae bio-source go far beyond the removal of chemically synthesized colorants, and include synergistic benefits of vastly reduced water consumption, chemical and fertilizer use, and carbon dioxide emissions,” says Avgol CEO Tommi Bjornman. “We will be demonstrating to FILTECH visitors that following an extensive development path, the fibers both absorb and retain a range of colors - such as vibrant greens and blues – and that we can even deliver a ‘heathered’ appearance for a more natural looking material, all without affecting the filtration, barrier quality or feel of the final product.”

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.
