• 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.

RadiciGroup took part in the Phygital Sustainability Expo, this year in its fourth edition, which was held in Rome on 5 and 6 July. This event is entirely dedicated to the ecological transition of fashion and design brands through technological innovation. The show is an important platform for discussion on sustainable transition issues, involving Italian and international brands, fashion tech start-ups, representatives from the institutional, business and educational fields, and consumers.

RadiciGroup's participation in the event was further evidence of the Group's commitment to making a contribution to sustainability and circularity in the fashion and textile industry, in collaboration with all the other players in the supply chain. During the narrated fashion show, held on the evening of Wednesday, 5 July, in the evocative archaeological complex of the Imperial Forum Museum, RadiciGroup presented a maxi dress made of Biofeel® eleven, a yarn of completely natural origin featuring high technical, aesthetic and environmental performance. This yarn is produced starting from a small bean cultivated in India on semi-arid land and thus does not compete with human food production. These beans yield a special oil ideal for obtaining biopolymers, such as the one produced by Arkema and spun into yarn at RadiciGroup in Italy.

The dress is not only made from a low environmental impact raw material, but is also an example of ecodesign: the garment was realized on a Shima Seiki WholeGarment knitting machine, where the entire item was knit directly from spools of Biofeel® eleven yarn, bypassing the traditional stages of weaving and tailoring. It is a zero-waste process, as only the quantity of yarn strictly needed for the garment is used.

Biofeel® eleven yarn endows the dress with unique characteristics, including low moisture absorption, greater lightness and high resistance and durability. Besides being 100% biobased, the yarn is also 100% recyclable because it is made of a mono-material polymer, which facilitates its end-of-life recycling and processing into new materials suitable for any application requiring high performance.

After nearly 30 years with the company, Matthew North, Commercial Director at the viscose specialty fibre manufacturer Kelheim Fibres, will retire on July 1, 2023. Throughout his long and successful career, he has played a significant role in transforming Kelheim Fibres from a supplier of standard fibres to the European textile industry into a supplier of predominantly customized specialty fibres for the hygiene, specialty paper, and textile industries.

Mark von der Becke will assume the position of Sales Director and become part of the management team at Kelheim Fibres. The 48-year-old brings extensive experience in sales, marketing, and key account management. He has held various leadership positions in renowned companies such as Hoechst, Clariant, and DS Smith in Germany, Switzerland, and China. He is known for successfully developing and implementing strategy and change programs.

Dr. Marina Crnoja-Cosic, who has been serving as Director of New Business Development and a member of the management team at Kelheim Fibres since 2020, will take on the responsibility for marketing and communications. She will now drive the further development of the marketing strategy and communication with customers and partners.

Trevira CS is exhibiting for the first time at CSI Miami (Cruise Ship Interiors Design Expo Americas). Taking place on 6 – 7 June, 2023 at the Miami Beach Convention Center, CSI will bring together buyers and suppliers involved in cruise ship interiors, including interior designers, architects, outfitters, shipyards and suppliers.
 
On the Trevira CS stand, visitors can get an idea of the wide range of flame retardant fabrics suitable for use on board cruise ships. 53 fabrics from 20 Trevira CS customers will be on display that either have IMO certification and/or have been tested to the fire safety standards (FTP Code) required in the marine sector. Trevira CS fabrics are inherently flame retardant, meaning that their flame retardant properties cannot be washed out or lost through aging or use. This is due to the chemical structure of the polyester fiber: the flame retardant properties are firmly anchored in the fiber and cannot be altered by external influences. A surface-applied flame retardant finish is therefore not necessary.

In the marine sector, the demands placed on textiles are not only high in terms of fire protection, but also with regards to light resistance and durability. This is particularly true for textiles used in outdoor applications. These must be extremely robust, as they are exposed to moisture and sunlight. To meet these requirements, Trevira CS has launched a range of 30 new spun-dyed, UV-stable filament yarns. Besides color depth and durability, spun-dyed yarns offer another advantage: They are more sustainable because the fabrics made from them can be produced in a more environmentally friendly way than textiles that are dyed in one piece or consist of brightly colored yarns. In fabric production, a large share of resource consumption goes to the dyeing and finishing of fabrics as well as the use of chemicals and water. However, with spun-dyed yarns, these processing steps are unnecessary – the yarn immediately comes out of the spinneret in the desired color, reducing the products’ environmental impact.

The topic of sustainability is also taken up in other Trevira CS products. For example, Trevira CS fabrics are available in recycled versions. They consist of fiber and filament yarns obtained in different recycling processes. Filament yarns are produced using recycled PET bottles, they contain 50% post-consumer recycled material. Recycled fibers are obtained using an agglomeration plant and in further processing steps from residual pre-consumer waste from production. They consist of 100% recycled material (pre-consumer recycling). All flame retardant recycled Trevira® products are GRS (Global Recycled Standard) certified.
Fabrics made from these yarns are marked with the Trevira CS eco trademark. The prerequisite for this is a recycled content of at least 50%. Among the fabrics presented at the Trevira CS trade fair stand are 8 fabrics bearing the Trevira CS eco brand.

The long-term goal in developing sustainable products is undoubtedly to enter a circular economy. For this new path, an innovative Trevira CS product development was launched, producing flame retardant fibers and filament yarns from chemically recycled raw material. In this case, the basic raw material for the chemical recycling was PET bottles, but essentially it could be most any other PET recyclables, such as packaging material or even textiles. Chemical recycling involves depolymerization, a sequence of chemical reactions in which the polymer chains are broken down again into their original components, i. e. the monomers. In a further processing step, impurities are removed. Before the polymerization process is initiated, a small amount of MEG (mono ethylene glycol) is added.

The same technology used to produce the original (virgin) raw material for Trevira CS is also used here. The flame retardant modification is added during polymerization. In this way, the flame retardant properties are indelibly anchored in the polymer.

By recycling valuable materials such as packaging material, waste can be avoided. The raw material obtained from the recycling process is comparable to the original material can be used again in high-quality products.

CHT and Fulgar have collaborated to support the goal of reducing the carbon footprint with an effective and sustainable solution for the textile market.

Combining FULGAR’s circular economy ready yarns with CHT’s resource-saving dyeing techniques significantly reduces the usage of natural resources and leads to lower environmental impact and ultimately a lower carbon footprint. The combined process needs less water, uses less energy, and saves time while meeting the color fastness standards for finished textile products.

The combination of 100 % biobased polyamide EVO® by FULGAR yarns with CHT sustainable dyeing application can save water up to 64 %, energy use up to 50 % and process time up to 50 %, when compared to standard dyeing processes. Sustainable dyeing of EVO® is promoted using CHT’s soy-based dyeing auxiliary SARABID TS 300. SARABID TS 300 has accredited a C2C Certified Material Health Certificate at Gold level and USDA Certified Biobased Product Certification.

EVO® by FULGAR, the totally renewable yarn based on castor plants, does not require high amounts of water - 4 times less compared to cotton. In addition to the sustainable aspect, EVO® by FULGAR offers characteristics like lower fiber weight, particular moisture management and higher stretch often without the need for elastomer fiber. This helps to avoid material mixes for better recycling opportunities. EVO® provides greater user comfort, mainly for performance and casual apparel.

• Reactive dyes for water and energy saving dye processes with significantly shortened process time

BEZAKTIV ONE covers a broad color spectrum with tinctorial very strong dyes. This enables a cost-efficient dye process with significantly less dye and salt. The excellent wash-off behavior allows short rinse cycles at lower temperatures and therefore offers further ecological and economic advantages. The dyes are particularly suitable for durable textiles due to their good multiple wash fastness.

Cellulosic fibers are often dyed with reactive dyes, as these are commercially available in a wide range of colors that result in dyeings with high wash fastness. However, reactive dyeings require a lot of water due to the necessary rinsing processes. Due to increased ecological requirements, the development of energy and water saving processes is not just a trend, but rather a core prerequisite for new dyes.

A minimal number of rinsing baths and generally lower temperatures for dye exhaust, rinsing and soaping contribute to an overall efficient water and energy saving dyeing processes.

BEZAKTIV ONE dyes can be dyed, rinsed and soaped between 40 and 60 °C. Therefore, the BEZAKTIV ONE exhaust dyeing process is significantly shorter compared to conventional reactive dyeing processes, where temperatures between 60 and 98 °C are required. This advantage means savings in process time and higher productivity for the textile dyer.

The advantages become particularly clear when dyeing medium to dark shades with the BEZAKTIV ONE process. Due to the high fixation level in combination with good color build-up dark shades can be matched with lower dye concentrations of BEZAKTIV ONE than with conventional bifunctional reactive dyes. The addition of the auxiliary COTOBLANC SEL in the second soap bath has an additional positive effect, so that a washing process with low water and energy consumption generates excellent wet fastness properties on the textile.

As a global provider of sustainable woodfibre products, Sappi will be showcasing its solutions for the garment industry under the theme “Fashion meets Forest” at ITMA 2023 – with sublimation papers and its dissolving wood pulp, used for the production of garment fibres under the “Verve” brand name.

How can the woodfibre industry support a more sustainable garments market? Sappi is eager to answer this question at the ITMA and has created a “knowledge trail” for visitors to explore under the motto “Fashion meets Forest”.

Klaus Steger (64), CEO of ERWO Holding AG (“ERWO Holding”) and Hoftex Group AG (“Hoftex Group”), will step down from the Management Board of both companies at the beginning of 2024 in accordance with internal policies of the family and the company regarding the retirement age. Already on June 30, 2023, ERWO Holding Management Board member Hans-Georg von Schuh will retire as planned. ERWO Holding Management Board member Manfred Heinrich will also leave the Board as planned at this time and will continue to hold his mandate as one of the managing directors in the Südwolle Group together with Stéphane Thouvay and Johannes Rauch.

Steger’s designated successor as CEO of both companies is Manuela Spörl (50), currently CFO of ERWO Holding and also CFO of Hoftex Group. Hoftex Group is a group of medium-sized companies in the textile industry, in which ERWO Holding holds a significant stake. In addition, ERWO Holding acts as the parent company of the Südwolle Group, in which the Group’s worsted yarn activities are bundled.

Spörl has a degree in business administration and has been working for Hoftex Group since 2000. Her professional career began in the Corporate Controlling department, and in 2012 she was appointed as an advisor to the Board of Management. She was granted power of attorney in 2015, followed by appointments as CFO of the Hoftex Group in 2020 and CFO of the ERWO Group in 2022. A search for a successor for Spörl in the position of CFO of the Hoftex Group and, subsequently, of ERWO Holding is currently underway. Until the new CFO takes office, the two members of the Management Board, together with the Supervisory Board, will ensure an orderly transition.

The announced change in the Management Board of ERWO Holding, which acts as the parent company of the Südwolle Group, also ensures continuity at the leading manufacturer of worsted yarns for weaving, circular and flat knitting products in pure wool and wool blends. In the future, the management of Südwolle Group will continue to consist of the longstanding members Manfred Heinrich (Technology, Production & Planning), Johannes Rauch (Finance & Controlling) and Stéphane Thouvay (Sales & Marketing and Product Management & Innovation). Together with the designated board member of the parent company ERWO Holding, they will continue the successful development of the Südwolle Group from a mere supplier to a strategic partner of its customers as well as the growth trend of recent years.

The founding family Steger remains involved in the various supervisory bodies of the group of companies and will continue to work closely with them as the sole shareholder of ERWO Holding.

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.
