From the Sector

The DiloGroup informs at Techtextil in Frankfurt (June 21 – 24, 2022) about new developments aimed at improving production technologies with a focus on needlefelts.

It becomes more evident that the textile industry comes into the focus of regulatory authorities who push respecting sustainability principles and who initiate a new body of laws. Hence all industrial sectors are requested to achieve savings in material and energy. The textile machine building, of course, plays an important role by seizing this initiative and offering solutions for fibre pulp recycling and reduction of energy, water and ancillaries. DiloGroup has made big efforts to meet these challenges together with a circle of partner companies. In this regard focal points of the development work are:

1. Intense Needling
   Needling per se is a mechanical production method with a high energy efficiency. For this reason, the development efforts of DiloGroup aim at producing nonwovens by “intense needling” instead of water entangling, even for light nonwovens made of fine fibres for the medical and hygiene sector with an area weight of 30 – 100 g/m². This would result in a reduction of the environmentally relevant production costs; per annum to about 1/3 to 1/5 of current.
   Despite the prospective advantages of the mechanical intense needling method over the hydrodynamical, water entanglement is at the moment the most important production method for low area weights and highest production capacity and is also offered by the DiloGroup as general contractor in cooperation with partner companies.
2. “Fibre Pulp Recycling”
   Fibrous material in nonwovens and particularly used clothes can be successfully recycled, if staple length can be conserved in the tearing process. In the classical tearing process, staple lengths are dramatically reduced and therefore these fibres can only be used as base material for inferior uses in thermal or acoustic insulation or in protective textiles, transportation or protective covers etc.
   When recycling textile waste in the context of the collection of used clothes, the so called “filament-saving” tearing using special tearing machines and methods must be used to produce fibres with longer staple lengths which can be fed to a nonwoven installation. Hence product characteristics can be better specified and controlled.
3. Additive nonwoven production
   The additive production method of the “3D-Lofter” is especially suited for automotive parts with differently distributed masses; but there may also be potential for increasing uses in the sector of apparel and shoe production.
4. “IsoFeed”-card feeding
   In the field of card feeding, the “IsoFeed” method offers great potential for a more homogeneous card feeding at the same time reducing the variation in cross-machine fibre mass distribution and thus the fibre consumption while conserving the end product quality.

• Natural fibers combined with bio-derived epoxy resins provide sustainable options for Industrial markets

Hexcel has developed a new product range that combines Hexcel resin systems made with bio-derived resin content with natural fiber reinforcements to create material solutions for Automotive, Winter Sports, Marine and Wind Energy applications.

HexPly Nature Range includes proven resins such as HexPly M49, M78.1-LT and M79 but with bio-derived epoxy resin content. The excellent resin characteristics remain unchanged in the new Nature Range products, maintaining high mechanical performance and consistent processing properties.
In addition, the HexPly Nature Range provides prepreg options with natural fiber reinforcements that can be seamlessly integrated into existing production processes.

Hexcel worked with TÜV Austria to provide independent, high-quality measurement and assessment of the bio-content of HexPly Nature Range products. TÜV Austria’s OK biobased certification uses a standardized measurement of the biobased carbon content enabling transparency and easy like-for-like comparison between products.

At JEC World in Paris on May 3-5, Hexcel presented an alpine ski produced by the Tecnica Group Ski Excellence Center which produces skis for Blizzard and for Nordica using HexPly Nature Range M78.1-LT UD flax fiber prepreg. In addition to providing a bio-based material solution, the natural fiber-reinforced prepreg also offers the potential to improve impact performance and vibration damping in the ski.

Claude Despierres, VP of Sales and Marketing – Industrial at Hexcel, said, “Our new HexPly Nature Range forms an important part of providing customers with biobased, TÜV-certified material options based on our established prepreg resin systems. Marine, winter sports, wind energy and automotive manufacturers can now have the choice to switch from petroleum-based material solutions to Hexcel HexPly Nature Range with no compromise in performance or process efficiency.”

Um erfolgreich zu segeln, muss alles zusammenkommen: Kraft, Ausdauer und Erfahrung des Teams, modernste Technik und bestes Material rund um das Boot. Besonders, wenn es um die Highspeed-Variante des Segelns geht, das Foilen. Durch gewölbte Tragflügel am Rumpf, die Foils, hebt sich das Boot beim Segeln aus dem Wasser, reduziert so den Wasserwiderstand und erreicht eine Spitzengeschwindigkeit von 35 Knoten bzw. 65 Kilometern pro Stunde. Die hohen Geschwindigkeiten und die raue Umgebung – Sonne, Wind und Salzwasser – stellen enorme Anforderungen an das verwendete Material. SEILFLECHTER produziert die notwendigen anspruchsvollen Seile und lässt sie von einem erfolgreichen Segler testen, Lukas Hesse.

Derzeit ist Lukas Hesse, 22 Jahre, Deutscher Meister 2020 auf der 49er Jolle, mit dem Schweizer Jann Schüpbach und der Hawaiianerin CJ Perez als „Clean Sailors Youth Racing Team“ beim 69F Youth Foiling Gold Cup am Start. Eins der fünf Rennen, die Bacardi Cup Invitational Regatta in Miami, hat das Team Mitte März auf ihrer Persico 69F gewonnen.

Das erfolgreiche Racing-Team arbeitet mit der gemeinnützigen Organisation Clean Sailors zusammen, die sich den besseren Schutz der Umwelt auf die Fahnen geschrieben hat und einen neuen Standard für sauberes Segeln innerhalb der globalen Segelgemeinschaft setzen will. Der Fokus liegt dabei auf langlebigen und performanten Materialien und dem Re- bzw. Upcycling von gebrauchtem Material. SEILFLECHTER unterstützt Clean Sailors bei diesen Vorhaben.

Lukas Hesse setzt voll auf die Top-Seile von SEILFLECHTER. Sie sind belastbar und robust und tragen so dazu bei, das Segeln umweltfreundlicher zu machen. Die Erfahrungsberichte von Lukas Hesse helfen SEILFLECHTER, die Seile kontinuierlich zu optimieren.

• The first year of TECHNYL® in China under the DOMO brand name; DOMO will be pushing forward its expansion plan of high-performance polyamides in China
• Continued innovation in engineered nylon materials for a sustainable future

DOMO Chemicals announced a long-term investment plan in China to continue expanding its production capacity of TECHNYL® high-performance polyamides. This plan aims to meet growing demand in the automotive, electrical & electronics, and industrial consumer goods industries, and help build a sustainable future. DOMO Chemicals acquired Solvay's Performance Polyamides business in 2020 and has sold the TECHNYL® products globally since February 1, 2022, including in China, one of the company's key strategic markets.

The global demand for polyamide materials is currently booming at a CAGR of up to 3 percent. The adoption of new energy vehicles (including pure electric, hybrid and fuel cell vehicles) is expected to reach 45 percent globally by 2030, and automakers are increasingly using sustainable materials to make components, which are key growth drivers of the polyamide market. In addition, the demand for miniaturized circuit breakers, contactors, plug switches, and other components in the electrical and electronics and industrial consumer goods industries further opens up the application potential for polyamide materials.

• Focus on the embossing technique applied to the recycled fabrics collection of the NATIVE Sustainable Textiles line

Performance Days, the leading trade fair on the latest trends in the development of fabrics for the functional textile industry, has as main focus the PERFORMANCE FORUM, where the most recent innovations and developments are presented with a prize awarded to the winner of the category chosen for the current year, which for 2022 will be “The Journey to Carbon Neutrality - CO₂ Reducing Technologies and Measuring Tools”.

Protagonists are therefore all those materials that contain carbon in reduced form and the strategies/technologies that companies implement to ensure the reduction of CO₂ emissions during production and how these reductions are actually measured (through energy saving, careful use of resources, use of more sustainable materials, local production and other technological and production measures).

In this sense, Sitip’s strategy for reducing CO₂ emissions and maximizing the use of resources is based on consolidating and optimizing the layout and logistics of the production plants, installing a cogeneration plant and a new generation smoke smoke abatement system and the transition to an energy-saving lighting system.

Regarding products, at Performance Days Sitip brings its latest innovations with an absolute focus on the embossing technique, a particular system of mechanical processes that can also be used on the recycled items from the NATIVE Sustainable Textiles line, a technology that is applied to fabrics produced with recycled yarns and chemicals with low environmental impact, implementing the GRS standard (Global Recycle Standard), result of the journey towards sustainability implemented by the company.

The collection of embossed designs combines performance, style and sustainability: thanks to special mechanical processes that combine heat and pressure, the fabric is embossed with geometric and design motifs for a more structured and palpable texture.

High-performance yarns now offer almost unlimited possibilities for replacing traditional raw materials in a vast range of technical applications. Often tailor-made, these filament yarns go way beyond the conventional idea of ‘textiles’ – finding new uses in sectors such as automotive, aviation, maritime, medical and construction, among many others.

Technical textiles are everywhere in our daily lives today, even if we may not always realize it. Some are in more obviously textile products, from sewing threads to artificial turf. But then, take cars as an example: modern vehicles are stuffed with parts made from sophisticated yarns. It’s common for producers of automotive parts now to send template material and requirement lists to Swiss Textile Machinery members, trusting their expertise and experience. Members operate development and testing centers with latest machine installations, where their experts devise customized solutions, as well as calling on the pure innovative spirit which is part of their DNA.

At the extremes
Technology drives applications beyond our current imagining in the case of Heberlein air splicers. Developed for a wide range of uses with high-strength technical fibers, they have no problems splicing aramid fibers up to 16’100 dtex, carbon up to 30’000 dtex, Dyneema up to 5’500 dtex, and glass up to 4’800 tex. Using compressed air, the splicers produce a tear-resistant, homogeneous splice of material without interfering knots.

Retech has the technology to achieve specifications for filament yarns, drawing and stretching fibers to perfection. Top heated godet rolls – many customized – are developed for high-performance fibers. Temperatures up to 400 °C can be achieved. Combining the right settings and wide speed ranges for each specific process results in unique end-products.

Fabric producers of high-end applications must avoid any quality risk. Yarn producers are well aware of this responsibility, so they use precision package winders for technical yarns, developed by Rieter’s subsidiary SSM. Taking yarns from ring twisting bobbins, its specialist finish winders can produce coarse-count technical yarns up to 50’000 dtex, offering a new level of flexibility and winding quality.

Lifestyle essentials
At first glance, motorists might fail to notice many of the technical yarns ‘hidden’ inside their cars. These products have functions such as providing stability with hardly any weight, or absorbing tensile forces at defined elongation. This kind of controlled elongation behaviour, for example, arises from the choice of textile material and the special construction of the yarns used.

Such specifications make twisting and cabling machines essential for the automotive industry. Saurer offers machines for the production of technical yarns made from a variety of feed materials in a very wide yarn count range. They are needed for vehicle products such as tire carcasses, toothed engine belts, seat belts, airbags and lorry tarpaulins.

Technical yarns also play a surprising role in our mobile devices. Tapping, scrolling and swiping are second nature for billions, with our phones and a plethora of other lifestyle essentials. Yet, how many people would know that the touch-sensitivity we take for granted on these screens is largely made possible by twisted glass fibers. Bräcker, part of Rieter’s components business, offers a selection of vertical sinter metal rings and nylon travelers for glass fiber twisting, so that mills can achieve high levels of productivity and quality.

Future unlimited
Automotive and communication technology are already important industries for Swiss Textile Machinery members, along with well-known technical textiles markets in sectors such as medical, transport and construction. Smart-wear is already noted as a field with significant potential. Naturally, members are constantly investigating other possibilities. Swiss textile machinery is already applied in energy (batteries), and plastics.

The Swiss Textile Machinery Pavilion will be at the Techtextil exhibition in Frankfurt, Germany, taking place from 21 to 24 June 2022.

Freudenberg Performance Materials announces a general upward adjustment of their prices for nonwoven performance materials for flooring and filtration applications in EMEA. This revision, effective January 1, 2022, has become necessary because of sustained and unprecedented surge in cost for raw materials, packaging, freight, consumables and energy combined with disruptions in their inbound supply chain.

Prices across all categories have by far outpaced their expectations and are forecasted to remain on high levels throughout 2022. This historic price trend has placed significant pressure on Freudenberg Performance Materials, and they understand in a similar way on their customers.

At this stage their business can no longer absorb the effects of such high price levels. Freudenberg Performance Materials will therefore adjust our prices for all their Colback® and Lutradur branded nonwoven products for flooring and filtration application by double-digit increases depending on product types.

Freudenberg Performance Materials will continue to work on improving productivity to offset inflationary pressure to keep attractive price levels and to avoid further price adjustments. They will continue to monitor the market development and in case of sustained and unexpected downward trends they will adjust our prices accordingly.

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.
