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.

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.

Automotive supplier, Yanfeng has been awarded a second consecutive A−rating by Carbon Disclosure Project (CDP) for the group's global leadership in transparency and action on climate change in 2022. Nearly 15,000 companies were rated based on data which they submitted to the organization. Yanfeng also received an Environmental Leadership Award by CDP China

CDP is a non-profit organization which operates a global disclosure system to enable investors, companies, cities, states, and regions to manage their environmental impacts. Every year, several thousand companies worldwide are analyzed about their strategic approach to the challenges of climate change and their climate management activities are rated on the basis of a comprehensive list of criteria. CDP’s annual environmental disclosure and rating process is widely recognized as the gold standard for corporate environmental transparency.

Yanfeng improved its scores in value chain engagement and climate-related requirements for suppliers, as well as targets for increasing low-carbon energy consumption or production.
“As our company-wide target for carbon neutrality, we aim to achieve 100% of our total energy consumption from renewable energy sources by 2030,” said Gunnar Büchter, Vice President of Global Sustainability at Yanfeng. All European plants converted to renewable energy by the beginning of 2022, and other regions also increased their utilization of renewable energy sources. Significant progress has been made in China. By end of 2021 a total of 30% of energy came from renewable sources.

The details of the proposed restriction of around 10 000 per- and polyfluoroalkyl substances (PFASs) are now available on ECHA’s website. ECHA’s scientific committees will now start evaluating the proposal in terms of the risks to people and the environment, and the impacts on society.

The proposal was prepared by authorities in Denmark, Germany, the Netherlands, Norway and Sweden and submitted to ECHA on 13 January 2023. It aims to reduce PFAS emissions into the environment and make products and processes safer for people.

All PFASs in the scope of the proposal are very persistent in the environment. If their releases are not minimised, people, plants and animals will be increasingly exposed, and without a restriction, such levels will be reached that have negative effects on people’s health and the environment. The authorities estimate that around 4.4 million tonnes of PFASs would end up in the environment over the next 30 years unless action is taken.

Peter van der Zandt, ECHA’s Director for Risk Assessment said: “This landmark proposal by the five authorities supports the ambitions of the EU’s Chemicals Strategy and the Zero Pollution action plan. Now, our scientific committees will start their evaluation and opinion forming. While the evaluation of such a broad proposal with thousands of substances, and many uses, will be challenging, we are ready.”

Next steps
ECHA’s scientific committees for Risk Assessment (RAC) and for Socio-Economic Analysis (SEAC) will check that the proposal meets the legal requirements of REACH in their meetings in March 2023. If it does, the committees will begin their scientific evaluation of the proposal. A six-month consultation is planned to start on 22 March 2023.

RAC will form an opinion on whether the proposed restriction is appropriate in reducing the risks to people’s health and the environment, while SEAC’s opinion will be on the socio-economic impacts, i.e. benefits and costs to society, associated with the proposal. Both committees form their opinions based on the information in the restriction proposal and the comments received during consultations. The committees also consider advice from the Enforcement Forum on the enforceability of the proposed restriction. Once the opinions are adopted, they will be sent to the European Commission who, together with the EU Member States, will then decide on the potential restriction.

An online information session will be organised on 5 April 2023 to explain the restriction process and to help those interested in participating in the consultation.

Over the past three years, a dedicated AI development team at BTMA member Shelton Vision has been developing tailored machine learning solutions for the textiles industry.

The aim has been to elevate the detection process and the accuracy of naming and grading subtle defects in textiles, in real time within production environments.

“Big Data ‘off-the-shelf’ systems such as those behind technolgies like facial recognition and Google Maps involve reading many thousands of single images each second and simply take too long to accumulate sufficient data for what’s required in this specific case,” says Shelton Vision CEO and Managing Director Mark Shelton. “A feature of the textile industry is that in many sectors, the product range changes several times within a year and it is not uncommon to have to inspect hundreds, if not thousands of different styles in a year based on precise settings.”

In terms of defect types, he adds, there may typically be over 100 that need to be accurately detected, classified (named) and graded in real time.

“Added to this is the need to ‘filter out’ the random occurrence of ‘non defects’, such as loose threads, lint and dust on the surface – the number of which can be higher than actual defects – and it is clear that a bespoke system is required.”
The development team has consequently established metadata for identifying defect properties, enabling the successful identification of faults from a much smaller number of images.

“The system employs a unique combination of machine learning for automated style training and novel algorithms for defect detection, to provide high quality images for the AI real time defect classification and grading software,” Shelton explains. “Due to the inherent variation in fabric features – raw materials, construction, texture, colour and finishes, as well as the differing product quality standards in value chains and the regional variations in what defects are called – our AI engine uses models built for each individual company or group of companies, or product value chain.”

The AI models are constructed so that the user operatives can populate them with their own data produced by the vision system or by obtaining defect images from another imaging source (eg a mobile phone camera).  

The occurrence of defects is sporadic and many defect types occur infrequently, although when they do, they can have severe consequences. These scenarios re-enforce the need for the AI engine to be quickly set up and able to operate accurately with limited data sets of typically between 30 and 50 good quality images per defect type.

A further feature is a tool enabling the user to periodically ‘clean up’ the AI data during the set up phase. This is used to resolve conflicting data and to correct mis-named images.

Generally, the highest cost component of fabric production is the raw material and in addition to finished product inspection, a cost effective use for vision systems is in process operation.

Generally, the highest cost component of fabric production is the raw material and in addition to finished product inspection, a cost effective use for vision systems is in process operation.

“There is a need for the real time detection of defects that are being created in separate processes, such as printing or coating and for real time automated systems that can accurately determine the defects and their severity and provide a reliable signal for an operative to rectify the issue, This can result in considerable savings.

Prior to Shelton introducing powerful customised machine vision and real time defect classification, the only systems available were those that required manual sifting through vast numbers of images, which included both real defects and ‘non defect’ images. The task was very often overwhelming and did not provide much benefit beyond manual fabric inspection.

Toray Industries, Inc., announced that it has combined nanotechnology and fiber technology to create a cross-shaped polymethyl methacrylate (PMMA) nanopore fiber that efficiently adsorbs pathogenic proteins in the blood.

The company developed this fiber by employing its PMMA hollow fiber membrane spinning technology. Changing the nanopore size on the surface and inside the fiber makes it possible to control the types of protein that this material adsorbs. This could become a fundamental blood purification technology for a range of protein adsorption columns that cause diseases.

The fiber’s cross-shaped cross section has a larger surface area than fibers with round ones. This provides much better contact between the blood and fiber and significantly enhances protein adsorption efficiency.

Toray is the only company to have commercialized a PMMA hollow-fiber membrane artificial kidney for dialysis treatment. Its new nanopore fiber benefits from PMMA’s good protein adsorption and biocompatibility. Using the structural formation of a stereocomplex from two PMMA types entangled spirally during the spinning process to form the fiber shape, Toray made it possible for the fiber itself to develop pores of several to dozens of nanometers. Depending on the pore size, large proteins cannot go inside the pores. If they are too small, they are not trapped. This enables selective adsorption of moderately sized proteins trapped in pores.

The fiber pore sizes are adjustable to the diameters of target proteins for a range of diseases. These include inflammatory proteins in sepsis, autoantibodies in autoimmune diseases, and causative proteins in chronic illnesses. Toray’s technology is thus fundamental to developing disease-causing protein adsorption columns to purify blood.

Toray’s cross-shaped cross section suppresses inter-fiber adhesion, increasing the surface area per volume and enabling highly efficient protein adsorption. For blood purification applications, higher capacity adsorption columns increase blood removal amounts from the body, which can be especially stressful for the elderly and children. The new fiber’s highly efficient protein adsorption should contribute to compact, high-performance protein adsorption columns.

Trützschler Card Clothing (TCC), technology leader in the manufacture of high-performance card clothings for textile yarn processing, is expanding its site in Neubulach, Germany. With the twelve-million-euro investment, the supplier for the international textile machinery industry is expanding its production, warehouse and office capacities. A groundbreaking ceremony will take place during the coming winter.

The new building will expand the warehouse and logistics area by 600 square meters, to make a total area of 2,800 square meters. In the optimized cube of the new hall, a modern warehouse system will double the storage capacity. There will also be a fully automated warehouse for coils for sawtooth wires. During the construction phase, logistics and shipping will be temporarily outsourced to Pforzheim-Büchenbronn.

The move into the new building is planned for 2024. TCC will also expand the range of services and the production intensity at the site, while optimizing the process flows. Trützschler intends to recruit the additional employees required within a short timeframe by hiring new staff and offering apprenticeships at the Neubulach site. TCC employs more than 130 people in Germany, with a further 220 people employed worldwide at locations in Brazil, China, India, Mexico, Turkey and the USA.

Overall, the production area will be expanded from 4,000 to 5,400 square meters. This will enable the process flows to be optimized. The office space will be increased to 1,000 square meters. An additional level of the building will provide modern workplaces for administration and sales.

The new building will also improve access and exit routes for truck traffic. This will provide considerable relief for the local neighborhood in terms of noise emissions and other factors. Good integration into the region is very important to Trützschler. All contracts for planning, construction and air conditioning technology have been awarded to local companies.

In the future, TCC will operate its production facility in Neubulach in a climate-neutral manner. This will contribute important progress toward achieving the ambitious climate goals of the Trützschler Group. The new production facility will meet the highest requirements for energy efficiency and climate protection. Heating is provided by process heat recovery and geothermal energy. In addition, the company produces green electricity via its own solar panels.

"By expanding our business here in Neubulach, we are strengthening our presence in this area and our leading global market position too," says Managing Director Peter Gäbler. The Trützschler Group SE is also investing in India to build a new site with over 100,000 square meters for the Spinning, Card Clothing and Nonwovens business units. "It is important to be close to the customer worldwide because our foreign companies make a significant contribution to the success of the Group," says Gäbler.

TCC achieved another record sales result in 2021. Demand for the technology components for carding fibers in spinning mills and for carding in nonwovens production has increased significantly. The steel sawtooth wires, which are wound onto coils and produced for customers around the globe, eventually get worn down by use in production processes – so it is necessary to replace them regularly. For this reason, further growth is expected in 2022 and beyond.
