From the Sector

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.

The Lenzing Group, a leading supplier of sustainably produced specialty fibers, and Renewcell, the Swedish textile-to-textile recycling pioneer, have signed a multi-year supply agreement to accelerate the transition of the textile industry from a linear to a circular business model. The agreement contains the sale of 80,000 to 100,000 tonnes of Renewcell’s 100 per cent recycled textile Circulose® dissolving pulp to Lenzing over a five-year period, for use in the production of cellulosic fibers for fashion and other textile applications.

“The textile industry must change. By signing the agreement with Swedish textile-to-textile recycling company Renewcell, Lenzing is able to further integrate recycling and accelerate the transition of the textile industry from linear to circular. As champions of sustainability, we know that moving towards a circular economy is vital to address the enormous textile waste challenges of the industry”, says Christian Skilich, Chief Pulp Officer of the Lenzing Group.

“Lenzing is a major player in our industry, with an inspiring track record of path-breaking technical excellence and sustainability leadership. Our new partnership fits perfectly into Renewcell’s strategy to accelerate the scale-up of circular materials by collaborating with fashion’s most important players. We are more than pleased to join forces with Lenzing with the shared goal of making fashion circular.” said Patrik Lundström, CEO of Renewcell, in a comment on the agreement.

Canopy, a not-for-profit environmental organization dedicated to protecting forests, species, and climate, welcomes the agreement between Lenzing and Renewcell.
“Accelerating the transition to low-impact, circular production is the challenge of the decade for the fashion industry. That is why this partnership between Renewcell and Lenzing is so refreshing – it will bring low-carbon Next Gen solutions to market at scale,” exclaimed Nicole Rycroft, Executive Director of Canopy. “With the climate and biodiversity clocks ticking, the race to circularity is one we need all companies to win.”
 
It is an essential part of Lenzing’s corporate strategy and ambitious sustainability targets to become a true champion of circularity and to offer TENCEL™ and LENZING™ ECOVERO™ branded specialty textile fibers with up to 50 percent post-consumer recycled content on a commercial scale by 2025. To reach this goal Lenzing partners with recycling pioneers like Renewcell.
Circulose® originates 100 per cent from textile waste, like old jeans and production scraps, and turns into dissolving pulp. It transforms textile waste and production scrap into new high-quality textile products.

Automotive carpets are typically multi-layered systems that can be challenging to recycle. By introducing a carpet made of 100% polyester, Autoneum now opens up new opportunities for vehicle manufacturers to meet their sustainability targets. The innovative carpet systems are fully recyclable, thus paving the way for an improved and more sustainable end-of-life recycling of electric vehicles. In addition, the high content of recycled PET as well as the zero waste and less energy-intensive production process further improve the carbon footprint of Autoneum’s new monomaterial needlepunch and tufted carpets.

Autoneum’s fully recyclable carpet systems ensure a closed material loop and are thus proof of the Company’s commitment to improving the sustainability performance of its products and manufacturing processes. The 100% polyester carpets build on the existing lightweight and particularly sustainable Autoneum Pure technologies: the carpet surface, for example, is made of Di-Light or Relive-1, while Hybrid-Acoustics PET is used for the decoupler. Thanks to Autoneum’s innovative alternative backcoating (ABC) process, which uses a thermoplastic adhesive instead of latex, the production of the new monomaterial needlepunch and tufted carpets also requires significantly less energy and no water at all.

Autoneum’s sustainable tufted carpet system made of 100% polyester is already in development for an electric model of a German vehicle manufacturer that will be available in Europe and Asia.

Confirming its commitment as a global sustainability player.

The Sharm el-Sheikh Climate Change Conference (COP 27) has turned out to be one of the most closely watched events in recent years, an opportunity to bring together leaders from around the world in the face of a pressing and undeniable need

Renaissance Textile in Laval, France has successfully started up a complete textile recycling line, delivered, installed, and commissioned by ANDRITZ Laroche, part of the international technology group ANDRITZ.

The ANDRITZ textile recycling equipment enabled Renaissance Textile to become the first French recycling platform dedicated to industrial end-of-life textiles. The project aims to produce new fibers from the collected post-consumer apparel, which will be used to weave new recycled fabrics in the end.

The new 12,000 m² plant is equipped with a complete tearing line whose design is the result of close collaboration between R&D specialists from ANDRITZ Laroche and Renaissance Textile, as well as customized trials carried out jointly by the two parties at the ANDRITZ technical center in Cours, France.

The new clothing produced based on this type of circular economy model thus reflects the social and sustainability commitments of Renaissance Textile in terms of decarbonizing the textile industry, the fight against global warming, autonomy in raw material sourcing, and promotion of local staffing, particularly for people who have been unemployed for a long time or are seeking to enter the labor market for the first time. By 2025, for example, Renaissance Textile plans to create no less than 110 direct jobs.

• Focus on the guiding principle of "textile intelligence" and sustainability

Long before sustainability became a trend in the textile industry, Schoeller Textil AG, which has been innovating technical fabrics and smart textile finishing technologies for more than 150 years, made it its mission to develop textile innovations in harmony with nature. Now the company is undergoing an extensive rebranding, whilst unveiling its strong brand foundation in the process. The result embodies the newly defined guiding principle of “Textile Intelligence” - the development and successful implementation of innovative textiles and intelligent textile technologies.

Innovations in the textile industry must meet requirements on several levels – offering both new and optimized solutions to sociological, ecological, and economic challenges of our time. Creating this holistic added value is firmly rooted in the Schoeller brand origin and is still the top priority in textile product development today. The brand essence has thus remained the same, but it has been embodied anew.

“At the beginning of the rebranding process, it was clear to us we had to root ourselves in (Swiss) tradition in order to fully realize Schoeller’s entire brand potential and successfully explore new, digital paths,” said Antonio Gatti Balsarri, Schoeller chief commercial officer.

“The goal of the rebranding is to communicate our traditional brand values in a completely new brand presence. The result was a sharpened brand profile, a clear brand strategy and tonality, as well as a clean, modern corporate design. We will specifically address our sustainability commitment through the expansion of digital touchpoints, their cross-media use, and an increased online presence. Simplified, straightforward, sustainable - in accordance with our greatest source of inspiration: nature.”

Transparency and Sustainability
Paramount to Schoeller’s corporate identity is the full disclosure of brand principles and transparency around all business divisions. A simplified logo design was established by reducing logo elements and colors for a modern look and feel that can be produced in a much more resource-efficient manner. Schoeller’s new brand mantra of “Textile Intelligence” speaks to its company mission of more than 150 years.

Schoeller has been a bluesign system partner from the very beginning and uses the Higg Facility Environmental Module (FEM) to assess sustainable performance. In addition to environmentally-friendly manufacturing processes and careful material selection, the highest quality and sustainability standards in production also mean guaranteeing fair working conditions. Schoeller follows a Code of Conduct that guarantees transparent production chains, environmental protection, and fair working conditions.

“Zero Textile Waste” becomes a targeted brand strategy. While the production of textiles and textile technologies is continuously being optimized to preserve resources, the manufacturing processes are often costly and complex. To this end, Schoeller offers new approaches to efforts around Zero Waste in the industry. Its new online shop, “Schoeller re-Fabric” sells textile remnants from production directly to designers and smaller productions to increase its overall production volume efficiency and avoid textile waste.

Freudenberg Performance Materials (Freudenberg) has launched an elastic variant of its flexible superabsorbers for modern wound dressings. These superabsorbers increase the comfort level for patients as well as enabling longer wear time, thus reducing the frequency of dressing changes. Freudenberg is debuting the elastic superabsorbers at this year’s Compamed in Düsseldorf, from November 14 – 17, 2022. Further highlights at the trade fair include components for more sustainable wound care, PU foams with directly applied silicone adhesives, and an innovative hydrophilic debridement foam.

Freudenberg uses a new technology to manufacture the elastic superabsorbers. Unlike other methods, this technology does not perforate or slit the material, thus achieving a high degree of consistent elasticity. Furthermore, the technology used by Freudenberg bonds the superabsorbent fibers more uniformly with the material, thus enhancing the integrity of this layer in the wound dressing.

“Our new elastic superabsorbers demonstrate yet again how Freudenberg components help increase comfort for patients, reduce the workload for nursing staff and lower healthcare costs. Our extensive technology platform and our innovative strength are the basis for this,” Dr. Henk Randau, SVP and General Manager Global Division Healthcare at Freudenberg Performance Materials, said.
