ITA presents innovations in the production of reinforcing fibres and in the textile processing of high-modulus fibres. It also shows the impregnation of high-modulus fibres with thermosetting and thermoplastic matrix systems.  

ITA will be exhibiting in hall 6 together with Textechno, Mönchengladbach, Germany, textile testing equipment and Maruhachi Fukui, Japan, Thermoplastic Composite Material Systems. The Interreg AACOMA project will also be presented at the stand. 

• 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.

Kelheim Fibres, a leading manufacturer of viscose speciality fibres, has joined Recycling Atelier Augsburg. Recycling Atelier Augsburg is a unique centre for research and development in the field of textile recycling. It is located at the Institut für Textiltechnik Augsburg an affiliated institute of Augsburg University of Applied Sciences. The two institutions founded the Recycling Atelier in June 2022 together with twelve partners from the German textile industry.

In the Recycling Atelier, the focus is on the triad of technical and ecological sense as well as economic benefit. In this way, the partners of the Recycling Atelier are standing up against fast fashion, outsourced corporate responsibility and a general decline in raw material quality, which often fuels downcycling - the low-quality reuse - of materials.

As a model factory, the Recycling Atelier Augsburg combines the most important processes of textile recycling and offers holistic and comprehensive research along the value chain," explains Georg Stegschuster, head of the Recycling Atelier Augsburg. The scientists research on all process steps of textile recycling: from material analysis to sorting, preparation and textile processing to sustainable product design. Comprehensive data collection and the use of artificial intelligence as well as innovative materials play a central role.

Kelheim Fibres is a producer of high-quality viscose fibres, which consist of cellulose, the main component of the renewable raw material wood, and are used worldwide for products in areas such as hygiene, textiles, and technical applications.

"In New Business Development as well as Fibre and Application Development, we follow the Open Innovation concept - the cooperation with the Recycling Atelier offers us an ideal platform for this. Here we work with partners to advance sustainability and performance," explains Maik Thiel, project manager at Kelheim Fibres.

Recycled cotton fibres are often very short or of uneven length, which makes further processing of 100 % recycled material a challenge. Adding speciality fibres from Kelheim Fibres should enable the production of high-quality new products, such as nonwovens. In the future, the fibres provided by Kelheim Fibres will also be made from recycled pulp.

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.

The biomass waste is then treated by the Gencrest patented Fiberzyme technology. Here, cocktail enzyme formulations remove the high lignin content and other impurities and help fibre fibrillation. The company's proprietary cottonisation process provides fine, spinnable cellulose staple fibres suitable for blending with other staple fibres and can be spun on any conventional spinning systems giving yarns sustainable apparel. Vybrana is produced without the use of heavy chemicals and minimized water consumption and in a waste-free process where balance biomass is converted to bio stimulants Agrosatva and Bio Fertilizers & organic manure.

HeiQ AeoniQ™ – technology for more sustainability of textiles – HeiQ (Austria)
HeiQ AeoniQ™ is the disruptive technology and key initiative from HeiQ with the potential to change the sustainability of textiles. It is the first climate-positive continuous cellulose filament yarn, made in a proprietary manufacturing process and the first to reproduce the properties of polyester and nylon yarns in a cellulosic, biodegradable, and endlessly recyclable fibre.
HeiQ AeoniQ™ can be manufactured from different cellulosic raw materials such as pre- and post-consumer textile waste, biotech cellulose, and non-valorized agricultural waste, such as ground coffee waste or banana peels. It naturally degrades after only 12 weeks in the soil. Each ton of HeiQ AeoniQ™ saves 5 tons of CO2 emissions. The first garments made with this innovative cellulosic filament fiber were commercially launched in January 2023.

TENCEL™ LUXE – lyocell filament yarn – Lenzing (Austria)
TENCEL™ LUXE is LENZING’s new versatile lyocell yarn that offers an urgently needed sustainable filament solution for the textile and fashion industry. A possible botanical alternative for silk, long-staple cotton, and petrol-based synthetic filaments, is derived from wood grown in renewable, sustainably managed forests, and produced in an environmentally sound, closed-loop process that recycles water and reuses more than 99 % of organic solvent. Certified by The Vegan Society, it is suitable for a wide range of applications and fabric developments, from finer high fashion propositions to denim constructions, seamless and activewear innovations, and even agricultural and technical solutions.

Nullarbor™ – Nanollose & Birla Cellulose (Australia/India)
In 2020, Nanollose & Birla Cellulose started a journey to develop and commercialize tree-free lyocell from bacterial cellulose, called Nullarbor™. The name derives from the Latin “nulla arbor” which means “no trees”. Initial lab research at both ends led to a joint patent application with the patent “production of high-tenacity lyocell fibres made from bacterial cellulose”.
Nullarbor is significantly stronger than lyocell made from wood-based pulp; even adding small amounts of bacterial cellulose to wood pulp increases the fibre toughness. In 2022, the first pilot batch of 260kg was produced with 20 % bacterial pulp share. Several high-quality fabrics and garments were produced with this fibre. The collaboration between Nanollose & Birla Cellulose now focuses on increasing the production scale and amount of bacterial pulp in the fibre.

Circulose® – makes fashion circular – Renewcell (Sweden)
Circulose® made by Renewcell is a branded dissolving pulp made from 100 % textile waste, like worn-out clothes and production scraps. It provides a unique material for fashion that is 100 % recycled, recyclable, biodegradable, and of virgin-equivalent quality. It is used by fibre producers to make staple fibre or filaments like viscose, lyocell, modal, acetate or other types of man-made cellulosic fibres. In 2022, Renewcell, opened the world’s first textile-to-textile chemical recycling plant in Sundsvall, Sweden – Renewcell 1. The plant will eventually reach 120,000 tons of annual capacity.

Sparkle sustainable sanitary pads – Sparkle Innovations (United States)
Globally, around 300 billion period products are discarded every year, resulting in millions of tons of non-biodegradable waste. Since most conventional sanitary pads contain up to 90 % plastics, they do not biodegrade for around 600 years. Sparkle has designed sustainable, plastic-free, biodegradable and compostable Sparkle sanitary pads. From product to packaging, they are made up of around 90 % cellulose-based materials with top sheet, absorbent core, release paper, wrapping paper and packaging made of cellulose-based fibres. Whether Sparkle pads end up in a compost pit, are incinerated or end up in a landfill, they are a more sustainable alternative compared to conventional pads that contain large amounts of plastics, complex petro-chemical based ingredients and artificial fragrances. When tested according to ISO 14855-1 by a leading independent lab in Europe, Sparkle pads reached over 90 % absolute biodegradation within 90 days in commercial composting conditions.

The UK’s new Business Secretary, Grant Shapps has visited the Henry Royce Institute’ hub in Manchester to seal the second phase of R&D investment in the institute of £95 million. Fibre Extrusion Technology Limited (FET) of Leeds, England had previously installed its FET-200LAB wet spinning system at the University of Manchester site and this proved to be a focus for the Business Secretary’s interest, as he discussed the project with FET’s Research and Development Manager, Mark Smith.

This wet spinning technology enables fibres to be derived from sustainable wood pulp to produce high quality apparel and trials are now underway to perfect this process. FET is a world leading supplier of laboratory and pilot melt spinning systems, having successfully processed more than 35 different polymer types in multifilament, monofilament and nonwoven formats.

During his visit, Shapps spoke of the investment programme as a means of reinforcing the UK’s standing as a leader in advanced materials research, development and innovation.

“R&D investment is a critical way to turbocharge Britain’s growth. Growing an economy fit for the future means harnessing the full potential of advanced materials, making science fiction a reality by supporting projects from regenerative medicine to robots developing new recycling capabilities, right across the country. Today’s £95 million investment will do just that, bringing together the brightest minds across our businesses and institutions to help future-proof sectors from healthcare to nuclear energy.”

The Henry Royce Institute was established in 2015 with an initial £235 million government investment through the Engineering and Physical Sciences Research Council and the latest £95 million sum represents the second phase of the investment.

Opportunities being investigated by Royce include lightweight materials and structures, biomaterials and materials designed for reuse, recycling and remanufacture. Advanced materials are critical to the UK future in various industries, such as health, transport, energy, electronics and utilities.

Fibre Extrusion Technology Limited (FET) of Leeds, England has installed a FET-200LAB wet spinning system at the University of Manchester which will play a major part in advanced materials research to support sustainable growth and development.

This research programme will be conducted by The Henry Royce Institute, which operates as a hub model at The University of Manchester with spokes at other leading research universities in the UK.

The Henry Royce Institute identifies challenges and stimulates innovation in advanced UK materials research, delivering positive economic and societal impact. In particular, this materials research initiative is focused on supporting and promoting all forms of sustainable growth and development.
These challenges range from biomedical devices through to plastics sustainability and energy-efficient devices; hence supporting key national targets such as the UK’s zero-carbon 2050 target.

FET-200 Series wet spinning systems complement FET’s renowned range of melt spinning equipment. The FET-200LAB is a laboratory scale system, which is especially suitable for the early stages of formulation and process development. It is used for processing new functional textile materials in a variety of solvent and polymer combinations.

In particular, the FET-200LAB will be utilised in trials for a family of fibres made from wood pulp, a sustainable resource rather than the usual fossil fuels. Bio-based polymers are produced from biomass feedstocks such as cellulose and are commonly used in the manufacture of high end apparel. The key to cellulose and other materials like lyocell and viscose is that they can be recycled, treated and fed back into the wet spinning system for repeat manufacture.

Established in 1998, FET is a leading supplier of laboratory and pilot melt spinning systems with installations in over 35 countries and has now successfully processed more than 35 different polymer types in multifilament, monofilament and nonwoven formats.
