From the Sector

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.

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.

• Sales of CHF 890.3 million in second half-year 2022
• EBIT margin of around 2% expected for full year 2022
• Order intake of CHF 1 157.3 million in 2022; order backlog of around CHF 1 540 million as of December 31, 2022
• Preparations for ITMA 2023 on schedule
• Implementation of action plan to increase sales and profitability ongoing
• Rieter site sales process on schedule

For Rieter, in addition to the geopolitical uncertainties, the 2022 financial year was characterized by three main challenges:
Due to the rapid rise in inflation, the exceptionally high order backlog of around CHF 1 840 million at the beginning of 2022 was processed at significantly higher costs. It was only possible to offset these higher costs in part by means of price increases and other remedial measures.

In order to safeguard deliveries, it was necessary to compensate for serious material bottlenecks, particularly in electronic components, which resulted in considerable additional development expenditure.

Major expenses were also incurred in connection with the acquired businesses (Accotex, Temco and Winder).

Sales
The realization of sales from the exceptionally high order backlog developed better than expected. With sales of CHF 1 510.9 million, Rieter achieved an increase of 56% compared with the previous year (2021: CHF 969.2 million). In the second half of 2022, especially in the fourth quarter, the measures introduced to address material bottlenecks had a positive impact. Consequently, sales increased to CHF 890.3 million compared with the first six months (first half-year 2022: CHF 620.6 million).

EBIT margin
The trend in the EBIT margin was strongly influenced by substantial cost increases, which could only be offset in part through price increases and other remedial measures. In addition, to compensate for material shortages, expenses were incurred in connection with the development of alternative solutions and the acquired businesses.

Rieter succeeded in improving profitability compared with the first half of 2022 due to the higher sales volume and offsetting measures to compensate for increased costs, and expects a positive EBIT margin of around 2% for the full year 2022 (2021: 4.9%).

Order intake
In line with expectations, the order intake of CHF 1 157.3 million in 2022 was below the record year of 2021 (CHF 2 225.7 million). The market situation is characterized by investment restraint due to geopolitical uncertainties, higher financing costs and consumer reticence in important markets.

Order backlog
The company had an order backlog of around CHF 1 540 million at the end of 2022, which thus extends well into 2023 and 2024. In 2022, Rieter recorded order cancellations of less than 10% of the order backlog of CHF 1 840 million at the beginning of the year.

Preparations for ITMA 2023 on schedule
Rieter has continued to boost its innovative capability and, in order to further extend its technology leadership, will present new innovative solutions at ITMA 2023 in Milan.

Action plan to increase sales and profitability
Implementation of the action plan to increase sales and profitability is ongoing. With regard to the profitability of the order backlog, which remains high, the implemented price increases in combination with a favorable trend in costs, particularly in logistics, are having an impact. In addition, progress was made in eliminating material bottlenecks and reducing expenses for the three acquired businesses.

Rieter site sales process
The sales process for the remaining land at the Rieter site in Winterthur (Switzerland) is proceeding according to plan. In total, around 75 000 m² of land will be sold. The Rieter CAMPUS is not part of this transaction.

Results press conference 2023
Rieter will provide further details on the 2022 financial year and an outlook for the 2023 financial year on March 9, 2023.

• Iconic 200 Series fleece to be the first fabric made from this new process.

Polartec®, a Milliken & Company brand, announces Polartec® Shed Less Fleece, a new milestone in its industry-leading efforts to reduce textile fiber fragment shedding. Shed Less is a process that combines yarn construction, knitting, chemistry, and manufacturing to reduce home laundry fiber fragment shedding by an average of 85%. The first fabric to receive this new technology is the brand’s iconic Polartec® 200 Series Fleece, the modern version of the original PolarFleece® launched in 1981, and in 1993, the first performance fleece knit from yarn made from recycled plastic bottles.

The Shed Less process works by engineering the lofted fibers that give fleece its soft hand the ability to resist breaking and rubbing off during home laundering, cited as one contributing factor to the spread of fibers fragments (commonly referred to as microfibers). Polartec® Shed Less Fleece achieves this while maintaining all of the attributes that continue to make Polartec fleece a staple of midlayer collections - lightweight, breathable and warm.

The brand used the AATCC (American Association of Textile Chemists and Colorists) TM212-2021 test method for fiber fragment release during home laundering. This test was conducted with large sample sizes to account for variability. The testing concluded that Shed Less Fleece reduced fiber fragment shedding by an average of 85% compared to the baseline fabric.

“In 2016 we began looking into how we might test for fiber loss because there wasn’t a lot of research on the issue.” said Aimee LaValley, Polartec Textile Development, Dye and Chemistry Manager. “This led to new products like Polartec Power Air™, new manufacturing processes, as well as our participation in the TextileMission workgroup to study the issue on an interdisciplinary basis.”

TextileMission was a three year collaborative initiative of academia and industry to reduce the impact of textile microplastics funded by the German Federal Ministry of Education and Research. Founding partners include The Association of the German Sporting Goods Industry, Hochschule Niederrhein - University of Applied Science; TU Dresden - Institute of Water Chemistry; Vaude Sport; WWF Germany; Adidas AG; Henkel AG; Miele & CIE; and Polartec, LLC.

Polartec® Shed Less Fleece will be initially launched in the United States and will be available to customers beginning March 1, 2023. The brand plans to apply the Shed Less process to many other industry-leading fabric platforms and manufacturing facilities around the world.

• Standard assesses fibre release, biodegradation and ecotoxicity for the first time

Testing service provider Hohenstein has worked with the project partners Trigema, Freudenberg, DBL ITEX and Paradies to create a new standardized test method for detecting and classifying the environmental effects of textiles during washing. DIN SPEC 4872 combines analysis of fibre release, biodegradability and ecotoxicity. The test method according to DIN SPEC 4872 shows how many fibres are released during textile laundering, how well these fibres degrade in wastewater and how harmful the fibre residues are to the environment.

Studies have shown that washing textiles releases microfibres into the wash water, which cannot be sufficiently retained by wastewater treatment plants. Synthetic fibres pose the greatest risk to the environment because of their longevity and inability to biodegrade. However, Hohenstein project manager Juliane Alberts does not give the all-clear for biodegradable fibres and natural fibres: "Biodegradability alone does not mean that pure natural fibres, for example, are completely harmless to the environment. They, too, remain in ecosystems until they completely degrade and can also have a negative impact. In addition, additives, auxiliaries or finishes used in textile production can further slow the degradation process and leach into the environment."

The new standard enables textile producers and suppliers to test, evaluate and compare products for fibre release during washing and environmental impact. Juliane Alberts sees this systematic evaluation as an opportunity for the textile industry to take the initiative on environmental impact: "Our reliable data can be used as a basis for more targeted product development. This is a way to actively and consciously control further environmental pollution."

Freudenberg Performance Materials (Freudenberg) is widening its product range of technical packaging textiles. Evolon® ESD protects automotive and industrial parts with electronic components from electrostatic discharge. This includes trim lines, dashboards, mirrors, steering wheels, etc.

The ESD (ElectroStatic Discharge) feature of the new Evolon® technical packing textile provides permanent electrostatic discharging protection and the fabric’s surface resistivity can be customized. This eliminates ESD damage to electronic components during transport because electrostatic charging due to movement and friction is safely prevented. As this kind of damage cannot be detected with the naked eye, Evolon® ESD helps to avoid failures which can occur after the final product is assembled and released. Manufacturers benefit from fewer complaints and warranty costs, as well as better end customer satisfaction.

Further protection feature
Unlike conventional ESD packaging solutions, Evolon® ESD also protects parts surfaces by avoiding micro-scratches or lint contamination. By using Evolon® reusable packaging to transport parts with highly-sensitive surfaces, customers reduce the number of damaged parts and the reject rate.

Additional benefits
Evolon® microfilament textiles are also extremely strong and are available in different weights to meet a wide range of requirements – from lightweight to heavy-duty. They can be used to pack and transport very heavy parts without damage. In addition, Evolon® fabrics are durable, and contain up to 85% recycled PET.

Archroma, a manufacturer of sustainable specialty chemicals and solutions for industries such as textiles, packaging & paper, paints and coatings, announced that it has secured all regulatory approvals required to complete the acquisition of the Textile Effects business from Huntsman Corporation (“Huntsman Textile Effects”).

Both parties expect the transaction, which was first announced on 09 August 2022, to close on 28 February 2023.

Archroma is a portfolio company of US-based private investment firm SK Capital Partners.
