From the Sector

After three years, VUB a.s again got the chance to actively participate in the European trade fair Techtextil 2022m being present at a joint stand of Czech companies active in production and application of technical textiles, organized by Clutex - Cluster Technical Textiles.

In cooperation with partners from academic and production sphere many products were developed over the past years, sold by VUB under the brand Clevertex. For the presentation at the fair, a wide range of ESD protective clothing for the electrotechnical industry and for each worker dealing with electrostatic discharge sensitive components was on display. As well as another product line of the Clevertex brand representing wearable skincare textile products with antiseptic effects based on purely natural textile materials.

Attention was paid to the advanced solutions for smart textiles and e-textiles products esp. electrically conductive hybrid threads based on ultrafine metallic micro-wires. A significant advantage of these threads lies in their full compatibility with standard textile manufacturing processes, and possibility of customization in terms of fineness, electrical conductivity and temperature resistance of individual thread. As an example of one of the applications of conductive threads, different types of woven elastic conductive ribbons were demonstrated, which could be used as bus bars or as textile conductors wherever a variable length of conductive element is required without the negative influence on their electrical resistance during the change the length.

• Target markets: automotive, furnishings, sports and technical apparel
• New product entry: radipeople® line of personal protective equipment

RadiciGroup is at Techtextil 2022, the leading European trade fair for technical textiles, taking place in Frankfurt am Main, Germany, from 21 to 24 June. On display in the RadiciGroup exhibition area are the Group’s latest products for the automotive, furnishings and apparel markets: from nylon and polyester yarn, including biosource and recycled lines, to nonwovens and the new radipeople® line of personal protective equipment (PPE).

Indeed, at Techtextil, RadiciGroup is showcasing RENYCLE®, a yarn obtained from recycled nylon; REPETABLE®, a polyester yarn from post-consumer recycled plastic bottles; RESPUNSIBLE®, a nonwoven fabric from recycled polypropylene; and BIOFEEL®, a brand identifying a yarn line obtained from renewable sources of both nylon and polyester.

Moreover, RadiciGroup is participating in a forum organized by the Technical Textiles Section of Sistema Moda Italia in collaboration with the Italian Space Agency (ICE) (Hall 12.1 – Stand C58), with the goal of introducing product innovations not only coming from a single manufacturer, but also from an innovative synergistic approach all along the supply chain, from raw materials to finished products. An example of this synergistic collaboration is the “Mars Spacesuit”, recently tested in the USA by analogue astronauts as part of a space medicine project designed to measure the vital signs of future astronauts and develop technologies to support the simulation of life in space and planetary environments. RadiciGroup teamed up with major Italian textile companies and supplied the materials to make the suits for the six analogue astronauts participating in the mission and coordinated the development of the technologies needed to create the technicalwear for use in extreme environmental conditions.

International technology group ANDRITZ will be presenting its innovative nonwovens production and textile solutions at Techtextil in Frankfurt from June 21 to 24. The ANDRITZ product portfolio covers state-of-the-art nonwovens and textile production technologies, such as air-through bonding, airlay, needlepunch, spunlace, spunbond, wetlaid/WetlaceTM, converting, textile finishing, recycling, and natural fiber processing. For Techtextil, special focus lies on technologies for textile recycling, needlepunch, airlay, wetlaid glass fibers and textile calendering.

TEXTILE RECYCLING TECHNOLOGIES BASED ON TEARING
With the acquisition of ANDRITZ Laroche SAS, ANDRITZ has expanded its product portfolio to include airlay and recycling technology as well as bast fiber processing technologies. Complete recycling lines for post-consumer and industrial textile waste to produce fibers for re-spinning and/or nonwoven end-uses are one focus of this product range. Customer awareness and regulations are forcing clothing brands to recycle their textile waste in their own products. Recycled fibers can also be used in the nonwovens industry for various applications, for example in the automotive industry, for insulation, mattresses, and furniture felts.

ANDRITZ Laroche offers a complete process range of tearing lines from 50 up to 3,000 kg/h, which can be used for almost all types of pre/post-consumer textile waste. The aim is to preserve the character of the original fibers, for example cotton, by maximizing fiber length, strength and feel.

Gebr. Otto is exhibiting at this year’s Techtextil from 21 to 24 June in Frankfurt. The Dietenheim-based textile company manufactures a selected range of functional high-tech yarns made, for example, of conductive, high-strength and flame-retardant fibres. Gebr. Otto’s aim at the trade fair is to make personal contacts and to expand regional technology chains. The textile solution provider is to be found, as in past years, at the BW-I joint stand in Hall 12.1 at Booth No. C80.

Growing demand for technical yarns
“In the industry Gebr. Otto is mostly known for its cotton yarns and twines,” says Robin Hefter, who is in charge of technical textiles at Gebr. Otto. Cotton is the fibre that is mainly spun in the company’s spinning mill. It has been Gebr. Otto’s main line of business for over 100 years. The technical yarns that have been in the company’s product range for a good five years are, by contrast, still relative newcomers. They account for around 10 per cent of the company’s output, their share of which is on the increase. “Technical textiles have proved to be a growth sector in recent years,” Hefter explains, “and due to current political events demand for them has increased even further.”

Portfolio with a protective character
That is a reference to personal protective equipment – clothing and gloves. Gebr. Otto’s highperformance functional yarns, many of which are based on high-tech fibres, are specially designed for use in this area. In addition to flame-retardant yarns made of meta-aramid Gebr. Otto processes antistatic or conductive fibres.

As a rule many chemical fibres are easily electrically chargeable without being able to discharge by themselves due to their low moisture absorption. That is why undesired discharges occur,
maybe even the next time you shake hands. In some situations, they can be life-threatening. “Imagine the team at a pit stop in a Formula 1 race,” Robin Hefter says. “refuelling a racing car
under pressure of time. There must not be a single spark, no matter how small.” That is why Gebr. Otto adds antistatic fibres to its technical yarns. They prevent electrostatic charging and
offer safety not only to pit stop teams but also to filling station attendants. If electric conductivity is required, conductive fibres are added. And high-strength fibres are used if high or ultra-high tensile strength is required.

Colour fastness rather than safety is required when it comes to spun-dyed yarns. The fibres take up the pigments more homogeneously than if they are dyed as yarn. They are much more colourfast and fade markedly less in sunlight because the pigment particles are better enclosed in the fibre.

The AVK – Industrievereinigung Verstärkte Kunststoffe – has once again presented its Innovation Awards to companies, institutes and their partners. Three composites innovations were recognised in each of the three categories – “Innovative Products/Applications”, “Innovative Processes” and “Research and Science” – at the new event JEC Forum DACH on 23 November 2021, the first edition of which was held in Frankfurt.

“As usual, the submissions included a lot of very interesting and promising products and processes this year. The Innovation Awards highlight the outstanding efficiency, cost-effectiveness and sustainability of fibre-reinforced plastics as well as the companies and institutes operating in the sector,” explains Dr. Elmar Witten, Managing Director of the AVK. The jury of leading experts from the industry honoured the following innovations this year:

Category “Research and Science”
First place in the “Research and Science” category was awarded to the German Aerospace Center (DLR) for its Bondline Control Technology (BCT). This innovative process is used for quality control and assurance of bonded joints. The core element is a porous fabric which is applied to a joining surface using an epoxy adhesive or matrix resin. Peeling away the fabric creates a chemically reactive and undercut surface and can also be used as a test to check adhesion to the substrate. BCT has potential in a variety of possible applications. For example, peel ply can be replaced by BCT fabric to produce composite components with an optimised joining surface. The cost-effective BCT peel test is suitable for coupon testing and process control. In addition, the combined adhesion test and surface pre-treatment can be used for quality assurance of bonded repairs on fibre composite structures.

Second place was taken by the Institute of Textile Technology (ITA) at RWTH Aachen University and its partners AEROVIDE GmbH, Altropol Kunststoff GmbH, Basamentwerke Böcke GmbH, TechnoCarbon Technologies GbR with “StoneBlade – Lightweight construction with granite for the wind industry”. This innovation enables manufacturers to reduce the amount of non-recyclable materials used in rotor blade construction. At the same time, it reduces the weight of these components and improves the mechanical properties relating to the stability of wind turbines. The innovative approach replaces glass-fibre reinforced plastic in the blade components with hard rock – a natural, cost-effective and recyclable lightweight material. The slabs of rock are cut and ground to a thickness of just a few millimetres and embedded in a fibre composite laminate with carbon fibre, which stabilises them for alternating load cases. The pre-stressed material is pressure-stable in the composite and can absorb tensile forces in the event of continuously alternating loads without any loss of stiffness.

Third place went to the Dresden University of Technology – Institute for Lightweight Construction and Plastics Technology (ILK) with its partner Mercedes Benz AG for the interdisciplinary development of a highly integrated inductive charging module for electric vehicles. The ultra-thin charging module was designed to make optimum use of space in the vehicle underbody without reducing ground clearance. An interdisciplinary approach was adopted for the development process. This involved the electrical, mechanical and process characterisation of high-frequency Litz wires, ferromagnetic foil and metal wire cloth as well as the creation of a simulation model. The result is a demonstrator for a charging system with a structural height of 15 mm and a total weight of 8 kg. It achieves a transmission efficiency of up to 92 percent at 7.2 kW nominal power and active air cooling. The hardware demonstrator was fabricated in a 3-step process using RTM and VARI techniques.

Kelheim Fibres GmbH is announcing that with effect from 01. October 2021, or as contracts and agreements allow, prices for its range of viscose fibres will be increased by €0,20/kg. In addition, freight cost adjustments will be applied on an individual customer basis. In cases where energy cost adjustments are not included in contracts and agreements, a temporary energy surcharge will be applied.

“The measures we are taking are absolutely necessary to ensure that Kelheim Fibres remains in a position to supply fibres with the levels of quality and service expected by our customers,” says Matthew North, Commercial Director of Kelheim Fibres.

The year 2021 has brought extraordinary challenges for society and for industry. Alongside the Covid-19 pandemic, recovering demand, disruption in the global freight systems and dramatically increased energy costs are driving significant cost increases for raw materials and negatively influencing supply chains. Prices for energy and freight currently lie well outside their historical ranges.

Es sei der Kelheim Fibres GmbH gelungen, die Auswirkungen der Pandemie auf die Faserproduktion zu begrenzen. Aber als Unternehmen mit eigener Kraft-Wärme-Kopplungsanlage und einem hohen Exportanteil in Staaten außerhalb Europas hätten sich diese Kostenfaktoren im zweiten und dritten Quartal 2021 stark negativ auf die Margen ausgewirkt. Da die Energiekosten auf einem beispiellos hohen Niveau verharrten und im vierten Quartal möglicherweise weiter ansteigen werden, keine Entlastung bei den hohen Frachtkosten absehbar sei und auch die Rohstoffkosten auf hohem Niveau blieben, müsse das Unternehmen Maßnahmen ergreifen, um eine weitere Margenerosion zu verhindern.

Kelheim Fibres GmbH had succeeded in limiting the impact of the pandemic on fibre production. However, as a company operating its own cogeneration energy plant and with a high level of export business outside Europe, these cost factors have had a severe negative impact on margins during the second and third quarters of 2021. With energy costs set to remain at unprecedentedly high levels and potentially increase further in the fourth quarter, no relief to the high level of freight costs foreseeable, and raw material costs also remaining at a high level, the company needs to take steps to prevent further margin erosion.

Kelheim Fibres’ Business Managers will be in contact with individual customers during September with further information.
