From the Sector

OETI – a member of the internationally active TESTEX Group – has bought the German company ECS to expand its service portfolio in the field of personal protective equipment (PPE).

OETI has been offering testing services for textile work clothing since 1983 – for about 40 years. Since the introduction of CE labelling for personal protective equipment and the enactment of the PPE Directive by the European Union in 1993, OETI has not only been testing textile personal protective equipment, but now on also certifies it in conformity with EU standards. In 1995, OETI was certified in Brussels as a Notified Body (0534) for type-examinations and quality assurance monitoring of personal protective equipment end products. Testing and certification is carried out in accordance with the current PPE Regulation (EU) 2016/425.

Testing and Certification Body for Eye and Face Protection, based in Aalen, was founded 15 years ago and is a globally active institution for testing and certification of eye and face protection equipment. The company is one of the leading independent testing institutions for personal protection products in laser applications and for welding work.

ECS tests and evaluates occupational health and safety goggles with and without a filter action, passive and active switching protection filters and shields for welders, and laser protection filters, goggles, and shields. The company also tests the optical properties of sunglasses, sports glasses, ski goggles, swimming goggles and motorbike goggles.

With OETI’s takeover, the ECS location in Aalen is retained, and all employees will continue working at ECS. The new Managing Director of ECS GmbH as of 1 July 2023 is Dipl.-Ing. Rolf Diebolder.

‘We are present on the European market, on the American market and, via a representative office, on the Chinese market. With the aid of the new distribution channels through OETI and TESTEX, we want to steadily advance ECS’ expansion and be present on all five continents’, says Managing Director Rolf Diebolder, explaining his strategic plans for ECS. ‘I would like OETI and ECS to develop a joint strategy in order to be able to offer existing and new customers of both companies a complete package which, when combined, will give us a unique selling point in the marketplace’, says Diebolder.

Diebolder also sees further potential in the cooperation with regard to protective laser clothing. According to him, this is where the laser laboratory commissioned by ECS could be used to make textiles laser-safe. In the future, there will be more and more ‘hand-held’ devices, i.e. laser welding devices, for which gloves and protective jackets are needed.

• ITA Master's graduate wins Hanns Voith Foundation Award 2023

In his Master's thesis, Flávio André Marter Diniz, a graduate of the Institut für Textiltechnik of RWTH Aachen University (ITA), developed ultra-thin polyethylene (PE) carbon fibres with a filament diameter 2-3 times smaller than usual. In addition, the use of PE-based precursors will make it possible to reduce the price of carbon fibres by 50 per cent in the future, thus opening up a wide range of other possible applications in key industries such as wind power, aerospace and automotive. For this groundbreaking development, Marter Diniz was awarded the Hanns Voith Prize with the Hanns Voith Foundation Award in the category "New Materials". The prize is endowed with € 5,000 in prize money.

Flávio André Marter Diniz won the prize in the category "New Materials" for his master thesis entitled "Investigation of the stabilisation and carbonisation process for the production of ultra-thin polyethylene-based carbon fibres".

The use of carbon fibres in highly stressed lightweight construction solutions, such as today's growth applications of wind turbines or pressure tanks, has become indispensable due to their excellent mechanical properties and low density. High manufacturing costs of conventional PAN precursor-based carbon fibres make the material very cost-intensive. In addition, it is not sufficiently available. New manufacturing approaches that develop alternative raw materials and manufacturing processes can be a key and growth engine for further industrial composites applications.

The aim of the work was to develop a new and cost-effective manufacturing process for high-quality ultra-thin carbon fibres using a polyethylene precursor. For this purpose, the sulphonisation process, which is time-consuming today, was to be significantly shortened. As a result, Mr. Marter Diniz produced novel ultra-thin polyethylenebased carbon fibres with a filament diameter < 3 μm with an excellent surface quality of the fibres without detectable structural defects. The fibre diameter is 2-3 times smaller than that of conventional PANbased CF. This provides the basis for mechanically high-quality material properties. At the same time, Mr. Marter Diniz was able to reduce the sulphonisation time by 25 percent. The developed material and technology set important milestones on the way to cheaper carbon fibres. With PE-based precursors, the price of CF can be reduced by 50 percent compared to conventional PAN-based CF.  

A total of five other young scientists were awarded in six categories (Drive Technology, Innovation & Technology/Artificial Intelligence, New Materials, Paper, Hydropower and Economic Sciences. This year, for the 10th time, the Hanns Voith Foundation awarded the Hanns Voith Prize to outstanding young scientists.

"ITA Aachen and ITA Augsburg are part of the ITA Group International Centre for Sustainable Textiles. Experience our textile innovations at two exhibition booths," explains ITA Institute Director Professor Dr. Thomas Gries. "See our ring spinning tester at booth H3-B304, which spins recycled fibres sustainably and individually in a previously impossible fineness. In addition, there is digital yarn monitoring, which enables new market potentials. Get an idea of the Recycling Atelier of ITA Augsburg at booth H3-A207 and see the textile cycle from used textile to solution steps for industrial implementation together with industry partners. Join us on the Walk4Recycling and follow the path from used textile to a new knitted pullover on a tour of the trade fair. This is how we live up to our claim as the ITA Group: sustainable - digital - individual."

ITA Aachen - Digital ring spinning tester for recycled fibres enables spinning of fine yarns with high recycled fibres content
The Institut für Textiltechnik of RWTH Aachen University (ITA) will be exhibiting a digital ring spinning tester, which spins recycled fibres directly and conventionally with a particularly high content of 60-70 percent. Up to now, recycled yarns have mainly been rotor-spun in this blend ratio. This results in rather coarse yarns and is not suitable for finer textiles such as outerwear. Ring spinning of recycled yarns now enables the spinning of finer yarns and thus a higher application level for recycled materials.

A unique selling point of the ITA ring spinning tester is the simultaneous spinning in the direct spinning process from the sliver and in the classic ring spinning process. For this purpose, the strength and elongation of the spun yarn are determined online and digitally for the first time. The real-time measurement allows process parameters and yarn properties to be adjusted iteratively and quickly. The ring spinning tester was upgraded from an existing tester to Industry 4.0 standard and is operated via a tablet. Operation via tablet enables the adjustment of process parameters including online quality monitoring remotely from anywhere in the world.
 
For this purpose, the ring spinning tester is also able to produce fine ring spun yarns. These yarns made from recycled material opens up a multitude of further fields of application for woven and knitted goods. Now, for example, clothing and technical textiles can be made from recycled material, the production of which was not possible before - such as outerwear made from recycled material. The development of new industries and fields of application opens up new market potential for recycled yarns - also and especially for processing in Europe. This creates the opportunity to preserve key technologies and jobs in cost-intensive locations.

ITA Augsburg - Recycling Atelier: Walk4Recycling
The Recycling Atelier of the Institut für Textiltechnik Augsburg gGmbH on stand H3-A207 presents the textile recycling from used textiles into new products via the various process steps and, together with the industrial partners, opens up solution paths for industrial implementation.

Under the headline "Walk4Recycling", a tour of the fair shows the cycle of used textiles from used knitwear into a new knitted pullover via a ring yarn made from a blend of 65 percent recycled cotton and 35 percent virgin polyester. The key innovation here is the high proportion of recycled fibres from post-consumer textiles for a ring yarn of this fineness. Today, mainly coarse rotor yarns for low-quality textiles are spun from these materials. The industrial partners participating in the Walk4Recycling are partners of the Recycling Atelier and contribute with their technologies to the fact that fibre material from old clothes can be processed in various process stages into a yarn of new value and high-quality ready-made garments.

The Walk4Recycling offers visitors the opportunity to experience a complete recycling cycle with the numerous process stages from tearing the old textiles, preparing and spinning the fibres and knitting a new jumper live during the fair. Get detailed information on the mechanical recycling of clothing via QR code, website and flyer about the participating exhibitors and their machines and technologies. A short movie will give you additional insights into the various processes involved in the production of the jumper.

At ITMA 2023 in Milan, Zünd is focusing on the advantages of digital single-ply cutting in modern garment production.

At the show, Zünd will demonstrate the advantages of individual cutting on demand and what benefits single-ply cutting of textiles offers. In the course of digitalization, the market environment of the apparel industry has changed. Producers are responding to increasing digitalization and ever-shorter product life cycles by investing in lean and highly automated production workflows. Solutions from Zünd supported process streamlining from ordering to cutting while minimizing manual interventions.

Zünd's single-ply cutters are the cutting tools in digitized production, offering manufacturers flexibility and profitability. Intelligent automation functions, optical solutions and software tools facilitate resource optimization, keep an eye on material consumption and support employees who can turn their attention to value-adding activities. With digital single-layer cutting, manufacturers speed up their cutting and expand their production capacities at the same time. They can accept orders at very short notice and easily meet delivery times thanks to highly economical and efficiently scalable on-demand production. Peaks in demand can be easily managed.

Zünd cutters give users new flexibility in their production workflow. He can work with complex motifs, demanding textiles and different shapes. The cutting technology enables the apparel industry to produce highly individualized customized garments in small batches and on demand just as economically and efficiently as in high volumes. It can process and handle more orders in less time. At the same time, both material and time are saved. In combination with the MindCut production software and precise single-layer cutting, there is almost no waste. The cut parts can be nested very close to each other and close to the material edges. This not only offers considerable savings potential, but also helps to reduce the ecological footprint.

• Electromagnetically heatable nanomodified stent for the treatment of hollow organ tumours wins second place at the RWTH Innovation Award

Almost every fourth person who dies of cancer has a hollow organ tumour, for example in the bile duct or in the oesophagus. Such a tumour cannot usually be removed surgically. It is only possible to open the hollow organ for a short time using a stent, i.e. a tubeshaped prosthesis. However, the tumour grows back and penetrates the hollow organ through the stent. Ioana Slabu from the Institute of Applied Medical Technology and Benedict Bauer from the Institut für Textiltechnik of RWTH Aachen University have now developed a novel technology for the therapy of hollow organ tumours, which was awarded second place in the RWTH Innovation Award. This involves a polymerstent that contains magnetic nanoparticles. When electromagnetic fields are applied, these nanoparticles lead to a controlled heating of the stent material and thus of the tumour. Because the tumour reacts much more sensitively to heat than healthy tissue, it is destroyed and the hollow organ remains open. Thus, the stent develops a self-cleaning effect.  

Ioana Slabu of the AME explains: "Not only can we drastically reduce treatment costs, but above all we can provide relief for millions of patients worldwide.
 
A manufacturing process and proof of concept for magnetic hyperthermia are already in place. This novel technology has a very high development potential because it can also be used for tumours in other parts of the body such as the prostate, stomach, intestine or urinary bladder or for cardiovascular diseases.  

The AiF/IGF project started under the project title "ProNano" funded by BMWK. Now the approval for the follow-up project "ProNano2" has also been received. The approved project is called: "Validation of the innovation potential of heatable stents for heat-induced treatment of cavity tumours" and is funded by BMBF in course of the VIP+ program. With the Clinic for General, Visceral and Transplantation Surgery of the University Hospital Aachen and the Institute for Technology and Innovation Management at RWTH Aachen University, the consortium is enriched by clinical and economic expertise. Every year, RWTH Aachen University honours particularly innovative university projects with the Innovation Award. Professor Malte Brettel, Prorector for Business and Industry, presented the certificates to four outstanding projects as part of RWTHtransparent.

ITMF has invited some of the start-ups that have presented at the ITMF Annual Conference 2023 to share in more depth during a series of interactive webinars their digital platforms/tools and how companies can benefit from digital workflows. The first webinar with the start-up “ColorDigital” took place in the first half of February. The second webinar will take place in March with the start-up “Frontier.Cool”.

In cooperation with the “Institut für Textiltechnik” (Institute for Textile Technology) of RWTH Aachen University, ITMF has developed a series of webinars that will have a closer look at the concept, political and legal environment as well as technology regarding circularity and recycling in the textile industry. In six webinars of 60-75 minutes each, international experts will discuss the backgrounds and potential of circularity in the textile industry. The webinar series start in March and will be completed by the end of May 2023.

The webinars are free of charge for ITMF members and all their affiliated members.

• Formula 1 cars will be cheaper in future

Carbon is the stuff Formula 1 cars are made of, at least the bodywork. But until now, carbon has been expensive. It can be produced more cheaply and efficiently if artificial intelligence monitors the production processes. A camera system combined with artificial intelligence automatically detects defects in the production of carbon fibres. This makes expensive manual inspection of the carbon fibres obsolete and the production price of the carbon fibre can be reduced in the long term.

For this idea, the young engineer Deniz Sinan Yesilyurt received the second prize of the "Digitalisation in Mechanical Engineering" Young Talent Award on 6 December.

Carbon fibres are sought after because of their good properties. They are very light - they weigh up to 50 percent less than aluminium. The combination of low weight and good mechanical properties offers many advantages. Especially in times of the energy transition, lightweight materials like carbon are more relevant than ever before. At the same time, carbon fibres are as resistant to external stresses as metals. However, achieving these good properties of carbon fibres is very complex.

Up to 300 individual fibre strands - bundles of individual fibres - have to be monitored simultaneously during production. If carbon fibres tear, it costs time and money to sort out the damaged fibres. This is just one example of various defects that can occur in the fibres during production.

Therefore, Deniz Sinan Yesilyurt attached a camera to the carbon fibre line that takes pictures of various fibre defects during production and collects them in a database. The artificial intelligence in the camera's information technology system evaluates the fibre defects by assigning the images to predefined reference defects. In doing so, it recognises various fibre defects with a classification accuracy of 99 per cent. The process can also be used in other areas that produce chemical fibres.

Deniz Sinan Yesilyurt received the prize from the German Engineering Federation (VDMA) in Frankfurt am Main, Germany. He is a Bachelor's graduate at the Institut für Textiltechnik (ITA) of RWTH Aachen University. The full title of his bachelor's thesis is: "Development of a Kl-supported process monitoring using machine learning to detect fibre damage in the stabilisation process". The VDMA awarded the prize to a total of four theses from different universities. The prize is awarded for outstanding theses and was offered in Germany, Austria and Switzerland.

As an accredited testing and certification body, the “OETI - Institut fuer Oekologie, Technik und Innovation GmbH“ (OETI for short) has been successfully responding to prevailing market requirements for 55 years and, in the process, has made a name for itself worldwide. To mark its anniversary, this international centre of excellence with its origins in Austria is taking a look back at the most important milestones in its history as well as providing interesting insights into future developments.

As renowned flooring manufacturers founded the Austrian Carpet Institute on 25th of September 1967, no one could have imagined how successful the company would become. But even back then, one thing was clear to the experts: the need to establish a carpet research and testing centre in the form of an association. Today, over five decades later, OETI is a testing and certification services provider for OEKO-TEX® certificates and labels, textiles, leather, due diligence along the textile and leather supply chain as well as for personal protective equipment (PPE), flooring technology, furnishings and indoor air quality.

In 1992, OETI was a founding member of the ‘International OEKO-TEX® Association for Research and Testing in the Field of Textile and Leather Ecology’ with independent certifications and product labels. Ever since, OEKO-TEX® has enabled companies along the textile and leather supply chain and every consumer to make responsible decisions for safe, environmentally friendly and fairly manufactured products.

In line with its focus on sustainability, OETI and its Swiss parent company, TESTEX AG, wanted to build the new OETI headquarters using low energy construction techniques and ensure its carbon-neutral operation. To achieve these goals, the highest possible thermal insulation and energy optimisation standards were applied, while the carbon-neutral power supply is generated by its in-house photovoltaics system as well as domestic renewable energy.

The new headquarters, which the company moved into in 2021, provides space for 75 employees over 2,500m2 and boasts bright and perfectly equipped office areas. The laboratory areas, the analytical/chemical laboratory and the physical / fire laboratory were also designed based on the latest methods and technologies. This makes OETI, alongside its Swiss parent company TESTEX, the second fully fledged laboratory site in the entire, global TESTEX Group.
