From the Sector

Trützschler expanded their portfolio to become the first full-liner in the preparation of textile waste – from mechanical recycling to the spinning preparation of torn secondary fibers.

The TRUECYCLED solution is the result of their cooperation with the company Balkan Textile Machinery INC.CO. in Turkey, which they announced at the ITMA 2023 trade event in Milan. Since then, Trützschler has received many inquiries for recycling systems.

Success with a systems approach
Recycling systems face significant technological challenges. On average, torn fibers are much shorter than virgin fibers. The percentage share of short fibers in the fiber mass is much higher. Unopened yarn and fabric particles are also difficult to process. Not surprisingly, much academic and practical research is currently conducted to find solutions for these problems. Dr. Georg Stegschuster, a researcher specializing in textile recycling, believes a systems approach is needed. He is working at the Recycling atelier, a model factory for mechanical recycling in Augsburg, Germany, which is committed to delivering the latest technological insights for textile recycling. “A perfect fine-tuning between tearing and spinning preparation is key for obtaining the best possible quality results and avoiding unnecessary fiber shortening,” he says. “This can be achieved if you are in control of both processes – and have the necessary expertise for both processes too.”

Gentle but effective
In some cases, for example, it may be advantageous to have less aggressive settings in the tearing line. This can help avoid unnecessary fiber shortening. The remaining higher share of unopened fabric must then be handled in a high-performance spinning preparation line. This starts with the right blow room configuration for perfect opening, cleaning and blending. A card that is specially designed for recycling materials, such as the new TC 30Ri, can also enable gentle but effective treatment of fibers.

A shortened drafting process is also a must. The integrated draw frame IDF 3 can make this possible. The draft is high enough to provide excellent levelling of the numerous short fibers, but low enough to prevent floating fibers.

Full-liner in mechanical recycling and preparation of textile waste
Trützschler now offers a complete system covering the whole process, from cutting and tearing textile waste through to carding and drawing secondary fibers. Thanks to this holistic approach and Trützschler’s expertise for the whole process, manufacturers can avoid unnecessary fiber shortening.

All shortlisted Trailblazers will also have the opportunity to showcase their businesses within an exhibit at the Summit to connect with other key industry stakeholders and potential investors.
 
The Trailblazer Programme corresponds with the theme of the upcoming Global Fashion Summit - ‘Unlocking The Next Level’. Inspired by a significant milestone, 2024 marks 15 years since the inaugural Global Fashion Summit was hosted in 2009. This pivotal anniversary offers a special moment to not only take stock of the evolution of the sector and the progress made so far, but, most importantly, look ahead at what actions must urgently be implemented in the near term, and the gaps that must be filled to accelerate industry transformation.

Fibre Extrusion Technology Ltd (FET) of Leeds, UK has appointed Dr Kristoffer Kortsen as Senior Materials and Process Scientist. He will report directly to R&D Manager, Dr Jonny Hunter, who joined FET in early 2023 in a growing Research and Development team.

Kortsen’s main area of work is in Gel Spinning of UHMWPE (Ultra-High Molecular Weight Polyethylene). His contribution will help provide gel spinning expertise and equipment in the near future to a range of industries including medical, aerospace, defence aerospace and marine.

He completed a Master’s in chemistry at KU Leuven, graduating magna cum laude in 2018. For his Master’s placement, he worked on the production of impact modifier additives for PVC at Kaneka Belgium. Continuing a partnership with this international chemical manufacturing company, he joined the Howdle group at the University of Nottingham for a PhD project looking into the industrial potential of scCO₂ dispersion polymerisations for additive production. After graduating, he worked in the Shaver group at the University of Manchester, developing a holistic approach to plastics recycling and sustainability across the many stakeholders in the field.

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.

More than 82 companies, businesses and social organizations – including AkzoNobel – are involved in a major Dutch research program focused on developing new technologies that will help solve some of today’s societal challenges.
 
Seven broad consortia have been established as part of the government-funded “Perspectief” program, with AkzoNobel set to play a leading role in the SusInkCoat project, which will explore how to make inks and coatings more sustainable.

The company will work together with private partners and other societal stakeholders to develop new materials, processes and applications to improve the durability, functionality and recyclability of coatings, thin films and inks. The program, which will run for the next five years, is backed by the Ministry of Economic Affairs and Climate Policy and the Dutch Research Council (NWO).

“Our discussions about collaborating with our SusInkCoat partners have been very positive,” says AkzoNobel’s R&D Director of Scientific Academic Programs, André van Linden, who is also the co-lead of SusInkCoat. “We’re all facing the same societal challenges – how to become more circular – and we’re looking for the same solutions in different application areas. But we’ve never done that together for this specific research topic, so we need an ecosystem to help us solve these challenges.
 
Van Linden adds that the program – one of many R&D projects the company is involved with – will also support AkzoNobel’s ambition to achieve 50% less carbon emissions in its own operations – and across the value chain – by 2030.
 
 “We want to make the recyclability of materials - such as furniture, building materials and steel constructions - easier by introducing functionalities like self-healing, higher durability and triggered release,” he continues. “The more you can leave the materials in their original state, the more sustainably you can operate.”

AkzoNobel will be collaborating with Canon, Evonik, GFB, PTG and RUG Ventures, who together possess extensive knowledge of market demands, supply chains and production processes. All the SusInkCoat partners will also work with academic researchers at several Dutch universities in an effort to identify promising developments that can be commercialized, used for education purposes or for outreach to the public.

Research being conducted by the other six consortia includes investigating methods to make tastier plant-based food; flat optics for more sustainable hi-tech equipment; and cheaper and more accessible medical imaging technology.

Fibre Extrusion Technology Limited (FET) has been awarded £50,000 of grant funding to collaborate with the University of Manchester on complex spin pack and spinneret designs. This funding will provide FET with access to the expertise of four universities and the National Physical Laboratory to develop the next generation of machinery.

The grant is awarded by a consortium led by AMPI (The Advanced Machinery and Productivity Institute) and NPL (The National Physical Laboratory). AMPI’s Innovation for Machinery (I4M) programme supports businesses in West Yorkshire and Greater Manchester as part of an overall initiative to drive innovation for the UK’s advanced machinery manufacturers to meet the challenges of developing new technology and entering emerging markets.

In this project, FET will be working with the University of Manchester to conduct computational fluid dynamics (CFD) studies on a number of complex spin pack and spinneret designs. The aim of this work is to identify areas of improvement for FET’s spin packs and spinnerets and to use computer aided designs to develop significantly more efficient versions. The goal is that the research will improve the throughput of FET extrusion systems, thus reducing the amount of polymer lost through inefficient flow paths. This development, in turn, will reduce the environmental impact of synthetic polymer processing.

FET designs, develops, and manufactures extrusion equipment for a range of high value textile material applications worldwide. Established in 1998, FET’s major strength has always been to collaborate with customers in testing, evaluating and developing high value materials with diverse, functional properties. Efficiency and sustainability are key, so enhanced development of spinneret technology will contribute significantly to these objectives.

A collaboration between Deakin University researchers and Australia’s largest commercial linen supplier Simba Global is tackling a critical global issue, the spread of harmful microplastics through our laundry.

Clothing and textiles are estimated to generate up to 35 per cent of the microplastics found in the world’s oceans, making them one of the biggest contributors. But there is still a lot to be learnt about the characteristics of these microplastics and exactly how and why they are generated.

Researchers at the ARC Research Hub for Future Fibres in Deakin’s Institute for Frontier Materials (IFM) have teamed up with Simba Global, a global textile manufacturing and supply company, to better understand the extent and type of microplastics shed when their products are laundered. Simba Global wants to lead the charge to reduce the environmental impact of textiles.

Lead scientist IFM Associate Professor Maryam Naebe said working with an industry partner on the scale of Simba Global meant the research could have a huge real-world impact.

Simba Global is the major linen supplier to Australia’s hospitals, hotels and mining camps, resulting in 950,000 tonnes of textile products – including bedsheets, bath towels, scrubs and much more – going through the commercial laundering process each year. It also supplies international markets in New Zealand, Singapore and the US.

“As part of our research, we will investigate potential solutions including the pre-treatment of textiles to reduce the shedding of microplastics, or even increasing the size of the plastics that break down so they can be better captured and removed by filtration during the laundering process,” Associate Professor Naebe said.

“Microplastics are now ubiquitous in the environment, they’re in the air we breathe, the food we eat and the earth we walk on. The magnitude of the problem is bigger than previously thought.

“Of serious concern is the mounting evidence that microplastics are having a negative impact on human and animal health. There are not just physical, but chemical and biological impacts.”

Associate Professor Naebe’s team have taken the first steps in the project, analysing wastewater samples from commercial laundries with high-powered electron microscopes in their Geelong laboratory, part of the largest fibres and textiles research facility in Australia.

The team recently presented a new scientific paper at the Association of Universities for Textiles (AUTEX) Conference 2023, which started the important process of formally categorising these types of microplastics, as well as developing standard terminology and testing methods.

“Because our understanding of microplastics is still in its infancy, we needed to start right at the beginning,” Associate Professor Naebe said.

“We need to have a standard definition of what is a microplastic. Up to this point that has been lacking, which makes it difficult to compare and incorporate other studies in this area.

“We are now developing a systematic method for sampling and identifying microplastics in laundry wastewater. It has been tricky to measure the different sizes, but this is important information to have. For example, there are studies that suggest some sizes of microplastics are causing more issues in certain animals.

“The next step will be establishing an essential method to prevent the release of microplastics from textile laundering. This may involve a coating on the surface of the textile or better ways to collect the waste during the washing process.”

Simba Global Executive Chair Hiten Somaia said the company had a strong focus on sustainability, driven by the business’ purpose statement.

“We are proud to partner with Deakin University in what is the first significant research into textile microplastic pollution in Australia. What we are most excited about is sharing the results of this research with all other textile markets in Australia – including clothing – and putting an end to microplastic pollution from textiles.”

Felix Pohlkemper and Tim Röding from Institut für Textiltechnik (ITA) of RWTH Aachen University are developing a technology with their start-up CarboScreen GmbH that makes complex carbon fibre production controllable through sensor monitoring. With the help of CarboScreen technology, it should be possible to double the production speed from the current 15 m/min to 30 m/min in the medium term. The doubling of production speed alone could result in an increase in turnover of up to €37.5 million per year and production plant. Felix Pohlkemper and Tim Röding were awarded third place in the AVK Innovation Award 2023 in the Processes and Procedures category for this ground-breaking development. The award ceremony took place during the JEC Roof Forum in Salzburg, Austria.

The production of carbon fibres is highly complex. In the current state of the art, however, the manufacturing process is only monitored manually by semi-skilled workers. However, even minimal fibre damage during production leads to a reduction in the quality of the carbon fibre. In extreme cases, it can also lead to plant fires. To ensure production quality, the production speed is currently limited to a maximum of 15 m/min. In fact, the production speed of the systems could be higher. The sensor-based online monitoring of Carbo-Screen makes it possible to increase the production speed to 30 m/min in the medium term. As a result of the increased production volume per system, the specific production costs of the carbon fibre are reduced, which can result in lower prices.

A reduced sales price would make it possible to use carbon fibres and their composite materials even more widely in traditional markets such as aerospace technology and wind energy, as well as for mass production in the automotive industry.

The CarboScreen online monitoring system is currently being developed for industrial use. It is to be validated at an industrial plant in 2024. CarboScreen GmbH was founded as part of EXIST funding and offers AI-supported sensor systems for carbon fibre production. The sensor technology continuously monitors the fibre throughout the entire production process. Deviations are detected automatically.

The winners of the AVK Innovation Award are honoured annually by the AVK Industrievereinigung Verstärkte Kunststoffe. Companies, institutes and their partners are honoured in three categories: products and applications, processes and procedures, and research and science.
