From the Sector

HeiQ AeoniQ Holding, a subsidiary of HeiQ Group, is appointing Julien Born as its CEO, leveraging his extensive executive leadership and profound textile industry expertise cultivated in prestigious organizations such as DuPont, KOCH Industries, and The LYCRA Company, where he served as CEO since 2021. Julien Born will champion the growth of the cellulosic filament fiber HeiQ AeoniQ™.

The HeiQ AeoniQ™ technology is poised for commercial production at the inaugural manufacturing facility in Portugal by the close of 2025. The just concluded €5M acquisition of land and buildings, within a 2-year project total investment of €80M, marks a pivotal milestone for the 15,000m2 facility in Maia, Porto. Situated strategically in Portugal's textile hub and a mere 20 minutes from a major commercial port, this facility is poised to catalyze the scale-up phase of the business, going from pilot manufacture to mass production when it wants to compete at full-scale on cost and performance with fossil fuel-based fibers.

HeiQ intends to consolidate the Group’s current and future activities in Portugal at the newly acquired site. This includes Shared Service Center functions as well as the Innovation Hub for the HeiQ Textile & Flooring business unit.

The recent addition of Julien Born to lead the charge follows the nomination of Robert van de Kerkhof to the HeiQ Board, a seasoned executive with extensive textile experience holding positions as CCO, CSO, Board member of Lenzing Plc, and Chairman of CIRFS, the European Man-Made Fibres Association. Robert will also serve as the Chairman of the HeiQ AeoniQ Holding Board.

HeiQ AeoniQ Holding, established as an independent subsidiary to attract new investors, value-chain partners, and brands, embarks on an ambitious multi-year scale-up strategy. This strategy involves integrating diverse sources of bio-derived feedstock and hyper-scaling cellulosic filament fiber production capacity over the next decade, targeting industries such as apparel, footwear, automotive, home textiles, and aeronautics.

Many end-users now expect recycled materials to be in textile products they purchase – and this is driving innovation throughout the industry. However, there are still many technical and economic issues facing yarn and fabric producers using recycled resources. Members of the Swiss Textile Machinery Association offer some effective solutions to these challenges.

Synthetic recycled materials such as PET can usually be treated similarly to new yarn, but there are additional complexities where natural fibres like wool and cotton are involved. Today, there’s a trend towards mechanically recycled wool and cotton fibres.

Spinning recycled cotton
The use of mechanically recycled fibres in spinning brings specific quality considerations: they have higher levels of short fibres and neps – and may often be colored, particularly if post-consumer material is used. It’s also true that recycled yarns have limitations in terms of fineness. The Uster Statistics 2023 edition features an extended range of fibre data, supporting sustainability goals, including benchmarks for blends of virgin and recycled cotton.
In general, short fibres such as those in recycled material can easily be handled by rotor spinning machines. For ring spinning, the shorter the fibres, the more difficult it is to guide them through the drafting zone to integrate them into the yarn body. Still, for wider yarn counts and higher yarn quality, the focus is now shifting to ring spinning. The presence of short fibres is a challenge, but Rieter offers solutions to address this issue.

Knitting recycled wool
For recycling, wool fibres undergo mechanical procedures such as shredding, cutting, and re-spinning, influencing the quality and characteristics of the resulting yarn. These operations remove the natural scales and variations in fibre length of the wool, causing a decrease in the overall strength and durability of the recycled yarn. This makes the yarn more prone to breakage, especially under the tension exerted during knitting.

Adapting to process recycled materials often requires adjustments to existing machinery. Knitting machines must be equipped with positive yarn suppliers to control fibre tension. Steiger engages in continuous testing of new yarns on the market, to check their suitability for processing on knitting machines. For satisfactory quality, the challenges intensify, with natural yarns requiring careful consideration and adaptation in the knitting processes.

From fibres to nonwovens
Nonwovens technology was born partly from the idea of recycling to reduce manufacturing costs and to process textile waste and previously unusable materials into fabric structures. Nonwovens production lines, where fibre webs are bonded mechanically, thermally or chemically, can easily process almost all mechanically and chemically recycled fibres.

Autefa Solutions offers nonwovens lines from a single source, enabling products such as liners, wipes, wadding and insulation to be produced in a true closed loop. Fibres are often used up to four times for one product.

Recycling: total strategy
Great services, technology and machines from members of Swiss Textile Machinery support the efforts of the circular economy to process recycled fibres. The machines incorporate the know-how of several decades, with the innovative power and quality standards in production and materials.
Stäubli’s global ESG (environmental, social & governance) strategy defines KPIs in the context of energy consumption, machine longevity and the recycling capacity in production units worldwide, as well in terms of machinery recyclability. The machine recyclability of automatic drawing in machines, weaving systems and jacquard machines ranges from 96 to 99%.

A major capacity expansion has been completed at AkzoNobel’s Powder Coatings site in Como, Italy, which will help secure supply to customers across Europe, Middle East and Africa (EMEA).

Four new manufacturing lines are now operational following the €21 million project – two of them dedicated to automotive primers and two to architectural coatings. New bonding equipment lines have also been added, ensuring that the products meet and exceed industry standards.

The extra capacity in Como has been installed in a renovated building where powder coatings were originally made – a sustainable reuse of an existing part of the site, which was established in 1992. The new lines also use recycled energy and are focused on meeting the highest standards in sustainable production, supporting the company’s ambition to reduce its carbon emissions by 50% by 2030.

AkzoNobel’s Como site is the company’s largest plant for producing powder coatings. It supplies products for market segments, such as home appliances, architecture, automotive, furniture and more.

In a judgment in December 2023, the Supreme People’s Court of the People’s Republic of China ruled in favor of Rieter in a legal dispute. The case concerned the infringement of a Rieter patent by a competitor’s draw frame. Rieter protects its innovations with patents and registered designs and consistently takes action against infringements of its intellectual property.

Rieter draw frames are known for their stable operation with high sliver quality and productivity. Scanning precision and autoleveling dynamics ensure outstanding sliver evenness and thus the production of high-quality yarns. Draw frames have also been the subject of a patent litigation by Rieter in China at various levels of jurisdiction. Rieter had sued a competitor for unauthorized use of its patented draw frame technology.

In the summer of 2022, the Shanghai Intellectual Property Court confirmed the patent infringement identified by Rieter and prohibited the accused competitor from continuing to use Rieter’s patented technology. The infringing party was also ordered to pay damages to Rieter.

The culpable competitor then appealed the decision of the Shanghai court to the Supreme People’s Court of the People’s Republic of China.

In December 2023, the Supreme Court of China in Beijing upheld the Shanghai decision, confirming that the patent had been infringed. As a result, Rieter’s competitor is prohibited from selling the infringing machine types and is required to pay the damages determined by the court.

This Supreme Court decision represents a major success for Rieter in defending its proprietary technologies in China. It is further proof that foreign companies can effectively defend their intellectual property in China.

As the technology leader in spinning machinery manufacturing, Rieter invests around 5% of its turnover annually in research and development. Rieter protects its innovative products with patents and registered designs and takes consistent action against infringements of industrial property rights.

In January 2024, ERCA Textile Chemical Solutions TCS was launched as an independent entity within the ERCA Group.

The decision to make ERCA TCS a separate company stems from the desire to focus exclusively on solutions for the textile industry and to build an agile entity oriented towards responsible research and production, while continuing to leverage a solid productive and financial background from ERCA S.p.A.

ERCA TCS aims to be the unique and innovative point of reference for textile companies in terms of products and services specifically designed for the needs of a sector that is currently facing challenges and opportunities related to sustainability and responsible production.

ERCA TCS bases its activity on the principles of "green chemistry" to offer the textile industry chemical solutions that make concrete the concepts of safety, performance, and circularity. Its flagship product - REVECOL® - is born from critical waste materials (used vegetable oils) and present in abundance, which through a process attentive to environmental compatibility and safety, are transformed into a line of innovative, certified, high-performance chemical auxiliaries usable by the entire textile industry.

ERCA Group has six plants in three macro-regions: Europe, Latin America, and Asia and produces chemical specialties and auxiliaries with an approach of responsible innovation. Its production covers several markets: textile, cosmetics, polyurethanes, concrete. It has a turnover of 150 million euros and employs 350 people worldwide, 100 of whom are in the sole Grassobbio plant.

Celanese Corporation, a specialty materials and chemical company, and Under Armour, Inc., a company in athletic apparel and footwear, have collaborated to develop a new fiber for performance stretch fabrics called NEOLAST™. The innovative material will offer the apparel industry a high-performing alternative to elastane – an elastic fiber that gives apparel stretch, commonly called spandex. This new alternative could unlock the potential for end users to recycle performance stretch fabrics, a legacy aspect that has yet to be solved in the pursuit of circular manufacturing with respect to stretch fabrics.

NEOLAST™ fibers feature the powerful stretch, durability, comfort, and improved wicking expected from elite performance fabrics yet are also designed to begin addressing sustainability challenges associated with elastane, including recyclability. The fibers are produced using a proprietary solvent-free melt-extrusion process, eliminating potentially hazardous chemicals typically used to create stretch fabrics made with elastane.

NEOLAST™ fibers will be produced using recyclable elastoester polymers. As end users transition to a more circular economy, Celanese and Under Armour are exploring the potential of the fibers to improve the compatibility of stretch fabrics with future recycling systems and infrastructure.

In addition to the sustainability benefits, the new NEOLAST™ fibers deliver increased production precision, allowing spinners to dial power-stretch levels up or down and engineer fibers to meet a broader array of fabric specifications.

A new research project links some of Denmark's leading researchers in PFAS remediation with artificial intelligence. The goal is to develop and optimise a new form of wastewater and drinking water treatment technology using artificial intelligence for zero-pollution goals.

In a new research and development project, researchers from Aarhus University aim to develop a new technology that can collect and break down perpetual chemicals (PFAS) in one step in a purification process that can be connected directly to drinking water wells and treatment plants.

The project has received funding from the Villum Foundation of DKK 3 million, and it will combine newly developed treatment technology from some of Denmark's leading PFAS remediation researchers with artificial intelligence that can ensure optimal remediation.

"In the project, we will design, construct and test a new, automated degradation technology for continuous PFAS degradation. We’re also going to set up an open database to identify significant and limiting factors for degradation reactions with PFAS molecules in the reactor," says Associate Professor Xuping Zhang from the Department of Mechanical and Production Engineering at Aarhus University, who is co-heading the project in collaboration with Associate Professor Zongsu Wei from the Department of Biological and Chemical Engineering.

Ever since the 1940s, PFAS (per- and polyfluoroalkyl substances) have been used in a myriad of products, ranging from raincoats and building materials to furniture, fire extinguishers, solar panels, saucepans, packaging and paints.

However, PFAS have proven to have a number of harmful effects on humans and the environment, and unfortunately the substances are very difficult to break down in nature. As a result, the substances continuously accumulate in humans, animals, and elsewhere in nature.

In Denmark, PFAS have been found in drinking water wells, in surface foam on the sea, in the soil at sites for fire-fighting drills, and in many places elsewhere, for example in organic eggs. It is not possible to remove PFAS from everything, but work is underway to remove PFAS from the groundwater in drinking water wells that have been contaminated with the substances.

Currently, the most common method to filter drinking water for PFAS is via an active carbon filter, an ion-exchange filter, or by using a specially designed membrane. All of these possibilities filter PFAS from the water, but they do not destroy the PFAS. The filters are therefore all temporary, as they have to be sent for incineration to destroy the accumulated PFAS, or they end in landfills.

The project is called 'Machine Learning to Enhance PFAS Degradation in Flow Reactor', and it aims to design and develop an optimal and permanent solution for drinking water wells and treatment plants in Denmark that constantly captures and breaks down PFAS, while also monitoring itself.

"We need to be creative and think outside the box. I see many advantages in linking artificial intelligence with several different water treatment technologies, but integrating intelligence-based optimisation is no easy task. It requires strong synergy between machine learning and chemical engineering, but the perspectives are huge," says Associate Professor Zongsu Wei from the Department of Biological and Chemical Engineering at Aarhus University.
