From the Sector

Kelheim Fibres and SUMO are presenting their high-performance absorbent pads for the reusable Sumo diaper at this year's Cellulose Fibres Conference. The Sumo diaper is a sustainable and washable cloth diaper made entirely from biobased materials, offering high performance and innovative design.

The Sumo diaper offers a reusable alternative, consisting of a waterproof shell and absorbent pads. To enhance the performance of the pads, Sumo collaborated with Kelheim Fibres, a leading viscose specialty fibre manufacturer with decades of experience in the hygiene sector.

Together with the Saxon Textile Research Institute STFI, Sumo and Kelheim Fibres have developed a high-performance absorbent pad that is free of fossil-based materials and has already been awarded the Techtextil Innovation Award. The basis for the innovative construction are Kelheim's functionalized specialty viscose fibres with modified cross-sections, which ensure particularly high absorbency and extremely low rewet values.

To ensure the washability of the product, needle-punched/thermally bonded nonwovens were chosen, consisting of a mixture of specialty viscose and PLA bicomponent fibres. By combining nonwovens, typically used in single-use applications, with reusable products, the partners have chosen a new approach.

Natalie Wunder, project manager at Kelheim Fibres, and Luisa Kahlfeldt, founder and designer of SUMO, explain in their joint presentation at the Cellulose Fibre Conference how open innovation has led to successful development collaboration, how this response to current consumer needs has emerged, and what steps are planned for the future.

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.

Freudenberg Performance Materials (Freudenberg) will present surfacing veils and core materials for lightweight fiber reinforced plastic (FRP) parts at JEC in Paris, France. Freudenberg will also be showcasing Enka® Solutions flow media and spacers for efficient vacuum infusion, resin transfer and foam injection molding processes for applications in the composites industry, etc. at the international composites show.
 
Freudenberg’s solutions for the FRP industry include a variety of glass, PAN and PET nonwovens, as well as core materials for the production of lightweight fiber reinforced plastic parts. These products are designed for anti-corrosion coatings in piping and tank construction, smooth UV resistant surfaces for facade panels, and other applications for a diverse range of end products. Products made from fiber reinforced plastics must be equipped with surfacing veils to provide abrasion resistance, corrosion resistance, smooth surfaces and mechanical strength. Freudenberg offers high-tech nonwovens that can meet these challenges.
 
Enka® Solutions products are characterized by their typical 3D entangled polymeric filament structures. Thanks to this structure, they are exceptionally suitable as flow media and spacers when producing composite materials.

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.

Price Trends

• The nearby cotton futures contract on the Intercontinental Exchange was down just 1% in December and closed the year at $1.84 per kilogram. A year earlier, the March contract closed at $2.30 per kilogram.  
  
  Cotton futures have been inverted for nearly three years because of supply chain disruptions that prevented normal on-time deliveries of international shipments. With the easing of container shortages and increased sailings, cotton futures are gradually reverting to the normal pattern in which contracts for forward delivery exceed nearby contracts by the cost of insurance, storage and interest between delivery months. The May and July 2023 contracts also finished 2022 at $1.84 per kilogram. In November, the May and July contracts were each several cents per kilogram lower than the March contract.
• The Eastern Market Indicator of prices for fine wool in Australia rose 9% in December to US$9.06 per kilogram. A year earlier, the EMI was $9.66. Australian analysts note that sheep for meat, cattle, and grain production, are competing alternatives for the use of land, and wool prices must continue upward if production is to be maintained in 2023.
• Prices quoted by the Indian Jute Balers Association (JBA) at the end of December converted to US$ fell 2% from a month earlier to an average of 74 cents per kilogram. The decline occurred entirely because of a weakening exchange rate. Prices in Rupee rose marginally. A year earlier, quoted prices averaged 84 cents per kilogram. The 16-percent decline year-on-year was caused about equally by a decline in quoted prices in Rupee and a weakening of the exchange rate.  
  
  The Indian jute industry is almost entirely focused on domestic demand, while half of total demand in Bangladesh comes from exports. Because of shortages of higher quality jute, export prices in Bangladesh are reportedly rising.

  India extended the anti-dumping duty at the end of December on jute and jute products imported from Bangladesh and Nepal for a period of five years. Bangladesh had urged the Indian government not to accept recommendations for extension, while the Indian industry was lobbying to ensure the duty remained in place. The duty rates range from approximately $6 per tonne at current exchange rates for low-quality fibres to $350 per tonne for finished products. The duty was originally imposed in January 2017 and was to expire at the end of 2022.
• Prices of silk in China rose 2% during December to US$28.0 per kilogram. Prices in yuan fell marginally during the month, but the RMB rose 3% against the USD. Prices of textile-grade silk in China were essentially unchanged at the end of 2022 compared with the end of 2021. However, prices closed 2022 about 40% above the average level pre-Covid. https://www.sunsirs.com/uk/prodetail-322.html and  https://businessanalytiq.com/procurementanalytics/index/raw-silk-price-index/ .
• Coconut coir fibre in India quoted in US$ remained in a narrow range, averaging $0.205 per kilogram in December. Prices in Rupee have been stable, and changes in dollar prices reflect changes in the exchange rate.

 
Production
 
World Natural Fibre Production in 2022 is estimated as of early January at 32 million tonnes, approximately one million below production in 2021 and down 900,000 tonnes compared with the estimate in early December.

World cotton production is estimated at 24.2 million tonnes in 2022/23 (August to July), 700,000 tonnes lower than in 2021/22 (ICAC.org). World cotton production rose from 20 million tonnes to 25 million between 2020/21 and 2005/06, but there has been no growth in the nearly two decades since.  
 
World production of jute is forecast down nearly 400,000 tonnes in 2022 because of inadequate rainfall during the harvest period to permit proper retting. Production in India is estimated up by 100,000 tonnes to 1.7 million tonnes, but production in Bangladesh fell by nearly one-third to just one million tonnes.
 
Production of coir, flax and sisal in 2022 are each estimated based on recent trends. Coir and flax have each been trending upward over the past decade, while world sisal production has been largely stable.

World wool production is forecast up 5% in 2022 to 1.09 million tonnes (clean), the highest since 2018. The Australian Wool Production Forecasting Committee issued its third estimate of 2022/23 production in December, keeping the estimate unchanged from September. Above-average rainfall in Australia, and across most of the Southern Hemisphere, is resulting in better pasture conditions and a rebuilding of sheep numbers. Sheep numbers shorn in Australia are climbing from 67 million in 2020/21 to 72 million in 2021/22 and to an estimated 75 million in 2022/23. https://www.wool.com/market-intelligence/wool-production-forecasts/  
 
According to the International Sericulture Commission (https://www.inserco.org/), silk production in China dropped from 170,000 tonnes in 2015 to 53,000 in 2020, with further declines estimated during Covid. Consequently, world silk production dropped from 202,000 tonnes in 2015 to 92,000 in 2020, and estimates of production during 2022 remain below 100,000 tonnes.

January, 3rd, ZDHC announced the release of the updated ZDHC Man-Made Cellulosic Fibres (MMCF) Guidelines Version 2.0, and its supporting document. By publishing these documents the industry shall be pushed forward increasingly innovative and sustainable fibre production.

The ZDHC MMCF Guidelines V2.0 now include the Responsible Fibre Production Guidelines, Wastewater Guidelines and Air Emissions Guidelines as three separate chapters in a single document.

Fibres are key components of production processes in the textile and fashion value chain and it is crucial to reduce the environmental impact of their manufacture. ZDHC guidelines give suppliers producing MMCF unified criteria for measuring output indicators like wastewater, sludge, air emissions and other process-related parameters.

Among other changes, this update reflects the expansion of the scope to accommodate Viscose Filament Yarn, Lyocell, Cuprammonium Rayon (Cupro) and Cellulose Acetate (Acetate). The ZDHC Man-Made Cellulosic Fibres (MMCF) Guidelines V2.0 provide an aligned approach for included fibres, including defined chemical recovery, wastewater and sludge discharge, and air emission discharge.

ZDHC continues to advocate for the improvement of processes which minimise emissions while also working towards the recovery of input substances and by-products. These dual goals, reduction and recovery, directly address the negative impact of outputs arising from MMCF production.

ZDHC MMCF Guidelines Industry Standard Implementation Approach Version 2.0: Additional Industry Support for Implementation
Along with the ZDHC Man-Made Cellulosic Fibres (MMCF) Guidelines V2.0, ZDHC has also updated its ZDHC MMCF Guidelines Industry Standard Implementation Approach. This document aims to support the implementation process of the ZDHC MMCF Guidelines V2.0, and features new implementation timelines that assist suppliers in setting their goals to achieve Foundational, Progressive or Aspirational Level on the ZDHC Supplier Platform.

December 29, Renewcell dispatched the first shipment of Circulose® dissolving pulp produced at its Renewcell 1 plant in Sundsvall to a customer. This sale is the latest step in the ramp-up of Renewcell 1 to its initial capacity of 60,000 tonnes per year.

Founded by innovators from Stockholm’s KTH Royal Institute of Technology in 2012, Re:NewCell AB (publ) (‘Renewcell’) is a multi-award-winning sustaintech company based in Sweden. The company’s vision is to make fashion circular. Through its patented process, Renewcell is able to recycle cellulosic textile waste, such as worn-out cotton clothes and production scraps, transforming it into a pristine new material called Circulose®.

Valérius 360 wanted to make a sustainable, circular approach possible in the fashion industry. Working together with Trützschler, a collaborative project has now achieved high-quality recycled yarn – opening up massive potential to drive measurable progress toward a circular and sustainable textile industry.

Testing at the Trützschler Technical Center
The team from Valérius 360 wanted to find ways of improving the processes for yarns made from 50 % recycled and 50 % virgin cotton (Ne30). In particular, it was seeking ways to reduce thick and thin spots, which disturb the appearance of the textile surface.

At the Trützschler Technical Center in Mönchengladbach, they conducted special trials that showed that using a direct spinning process for this application delivers much better results than a process with a draw frame passage for rotor yarns.

In direct spinning, the sliver from the card is directly drawn in the draw frame which is integrated in the can stock. This involves one less process step than using an autoleveller draw frame, while also saving space and giving staff more time for other operations.

On-site support from Trützschler Customer Service
The team from Valérius 360 also received in-house training from the Trützschler Customer Service department. Together, they analyzed and significantly improved the process at the Valérius 360 production site. This helped to bring yarns made from recycled raw materials up to the required level of the 50% Usterstatistics. This is the reference level for yarns made from virgin raw materials. Accordingly, 50 % of all yarn producers with raw cotton for rotor yarns and comparable yarn counts produce a poorer quality.
