From the Sector

wear2wear is an innovative industrial partnership dedicated to high-quality and sustainable clothing. Five expert partners in Europe have come together to cover the entire recycling loop. On cutting-edge production systems, textile fibres from used clothing will be turned into functional fabrics. Schoeller Textil AG is supplying a wholistic textile portfolio for the workwear area. At Schoeller Textil, the recyclable, functional fabrics from the wear2wear concept belong to the Inspire fabric group. These are high-quality protective workwear fabrics made of 100 percent polyester, which offer the greatest clothing comfort and often feel just like cotton. They are also compliant with the stringent requirements of the bluesign® system.

The sustainable wear2wear concept is synonymous with high-quality, responsible clothing. In European operations, textile fibres from used garments are used to produce new functional fabrics. Depending upon the area of intended use, they also meet strict waterproofing, breathability, protection and comfort requirements. To ensure that the raw material cycle comes full circle, these textiles can be recycled again when they reach the end of their service life. As a result, there is no waste, and they go on to produce new garments. As the wear-2-wear partner companies guarantee that – from the quality of the raw materials to the guaranteed recycling end process – these are 100 percent recyclable, functional fabrics made of recycled textile fibres. Water- and dirt-repelling technologies based on renewable raw materials, along with the most advanced membrane technology, will ensure that the textiles are manufactured and impregnated entirely without the use of PFC in the future too.

Five partner companies  
The five European partner companies in the wear2wear cooperation cover the entire recycling loop. Heinrich Glaeser Nachfolger GmbH is a German fibre and yarn producer and the “recycler” in the loop. Märkischen Faser GmbH (D) is the “upcycler” and fibre manufacturer. Carl Weiske GmbH & Co. KG (D) develops the polymers, fibres, yarns, chemical additives and textile systems, and TWD Fibres GmbH (D), a fully-integrated filament yarn producer, covers the entire range of polyester and polyamide 6.6 continuous filament yarns. Schoeller Textil AG, the innovative Swiss company, is responsible for textile production and manufactures sustainable high-tech fabrics with maximum clothing comfort. The matching climate-neutral and similarly 100 percent recyclable PTFE and PFC-free membrane, as well as recycled outer materials and linings, are supplied by Sympatex Technologies (D), the ecological alternative among the textile function specialists. DutchSpirit is a Dutch company which has been dedicated to environment-friendly clothing since 2010. Its mission is to significantly increase the awareness for sustainable clothing and offer recyclable clothing in the workwear segment. DutchSpirit is the initiator for the development of the Inspire products from Schoeller Textil and provided the inspiration for the wear2wear concept. Further garment-making partners who now also belong to the cooperative group include: Anchor Workwear BV (NL), Hüsler Berufskleider AG (CH), Groenendijk Bedrijfskleding BV (NL), Bedrijfskledingdiscounter BV (NL) and Rifka'S (NL).

At ITMA 2019 in Barcelona from June 20-26 FONG’S Europe, a member of CHTC FONG’S International Group, will be providing details of its new THEN Supratec LTM hydraulic long-tube dyeing machine.

This machine is distinguished by the ability to vary the angle of the Then Flexkier for either dry (jet) or wet (overflow) mode dyeing, in order to optimise the dye liquor ratio – from 1:15 down to 1:4 – depending on the materials being dyed.

This translates into considerable savings in auxiliaries, water and energy.

The Supratec LTM is suitable for the treatment of both woven and knitted fabrics ranging from the most sensitive articles to heavyweight materials within the weight range of 25 g/lm to 380 g/lm, and operates at very low tension due to the extremely low lifting height between the variable nozzle and the plaited fabric.

“Existing Supratec machines on the market are providing excellent performance for a wide range of delicate synthetic fabrics, from polyester to polyamide with high content of elastane,” says FONG’S Europe Director of Sales and Marketing Richard Fander. “Heat-setting can often can be avoided, which improves the handle of the material and saves costs and the lengthwise-elongation of the fabric being treated is lower than on winch-driven machines.”

• Hexcel’s Composite Innovations For Aerospace, Automotive, Energy And Marine Applications At JEC World 2019 Hall 5 - Stand J41

STAMFORD, Conn. – At this year’s JEC World taking place in Paris on March 12-14, Hexcel will promote a wide range of composite innovations for customer applications in aerospace, automotive, energy and marine markets.

Aerospace Innovations

Hexcel’s HiTape® and HiMax™ dry carbon reinforcements were developed to complement a new generation of HiFlow™ resin systems, producing high quality aerospace structures using the resin infusion process. HiTape® was developed for the automated lay-up of preforms and HiMax™ is a range of optimized non-crimp fabrics (NCF). Both products incorporate a toughening veil to enhance mechanical properties, meeting the structural requirements for aerospace parts.

Visitors to JEC will see an Integrated Wing Panel demonstrator and an I-beam, both made with HiTape® reinforcements, and an Opticoms rib made with HiMax™ NCF. The Opticoms rib and I Beam were both manufactured using C-RTM (Compression Resin Transfer Molding). They were injected with Hexcel’s RTM6 resin in a process taking less than 5 minutes. The total manufacturing cycle for both parts was just 4.5 hours.

Also among the Aerospace exhibits, Hexcel will display a composite petal for a satellite antenna, manufactured by Thales Alenia Space Italia. The petal is part of a set of 24 deployable structural elements that form the large area reflector assembly used on board Low Earth Orbit (LEO) observation satellites. Thales Alenia Space Italia selected Hexcel’s HexPly® M18 prepreg for this application, acknowledging the superior mechanical and outgassing properties provided.

Another Hexcel prepreg application on show is a “zero” frame, manufactured by Aerofonctions for the engine area of Daher’s TBM 910/930 single-engine turboprop aircraft. Hexcel’s HexPly® M56 prepreg was selected by Daher for the “zero” frame – a product developed for Out of Autoclave applications that provides the same high quality and performance as autoclave-cured prepregs, from a simple vacuum bag cure in an oven.

With 50 years of experience behind its comprehensive range of high-strength, high-strain PAN-based carbon fibers, Hexcel continues to innovate, and is introducing two new fibers to its portfolio. HexTow® HM50 combines high modulus and high tensile strength, making it ideal for commercial and defense aircraft and engines. HexTow® 85 was developed specifically to replace rayon-based carbon fiber for ablative applications.

HexTow® carbon fiber holds the most qualified carbon fiber positions on aerospace programs in the industry and is the best unsized fiber available on the market. It provides excellent bonding interfacial properties with thermoplastic matrices and is the best-performing fiber for 3D printing applications.

Additive manufacturing is another area of expertise for Hexcel, using PEKK ultra-high performance polymers and HexAM™ technology to manufacture carbon-reinforced 3D printed parts. This
innovative process provides a weight-saving solution for intricate parts in highly demanding aerospace, satellite and defense applications. HexPEKK™ structures offer significant weight, cost and time-to-market reductions, replacing traditional cast or machined metallic parts with a new technology.

Hexcel is well known for its range of weight-saving, stiffness-enhancing honeycombs and the company adds value by providing a range of engineered core solutions to customers from facilities in the USA, Belgium and the newly opened Casablanca plant in Morocco. Hexcel’s engineered core capabilities enable highly contoured parts with precision profiling to be produced to exacting customer specifications. An example of such a part will be on display at JEC. Made from Aluminum FlexCore®, the part is CNC machined on both sides, and formed and stabilized with both peel ply and flyaway layers of stabilization. Aircraft engines benefit from a number of Hexcel core technologies including HexShield™ honeycomb that provides high temperature resistance in aircraft engine nacelles. By inserting a thermally resistant material into honeycomb cells, Hexcel provides a core product with unique heat-shielding capabilities that allows for the potential re-use of material after a fire event.

Hexcel’s Acousti-Cap® broadband noise-reducing honeycomb significantly improves acoustic absorption in aircraft engine nacelles. The acoustic treatment may be positioned at a consistent depth and resistance within the core, or can be placed in a pattern of varying depths and/or resistances (Multi-Degrees of Freedom and 3 Degrees Of Freedom), offering an acoustic liner that is precisely tuned to the engine operating conditions. These technologies have been tested at NASA on a full engine test rig and meet all 16 design conditions without trade-offs.

HexBond™ – the new name in Adhesives

Hexcel’s range of high performance adhesives has expanded considerably following the company’s acquisition of Structil. The company has now decided to unite the range by marketing all of its adhesive products using HexBond™ branding. The comprehensive range of HexBond™ structural film adhesives, foaming adhesive films, paste adhesives, liquid shims, epoxy fillets and Chromium free liquid primers is suitable for a wide range of applications in combination with Hexcel’s prepreg and honeycomb products.

Automotive Innovations

Hexcel’s carbon prepreg patch technology provides an innovative way of locally stiffening and reinforcing metal parts, providing noise and vibration management functionality. HexPly® prepreg patches consist of unidirectional carbon fiber impregnated with a fast curing epoxy matrix that has self-adhesive properties, enabling it to bond to metal in a highly efficient one-step process. These key technology properties are demonstrated in an 18.5kg aluminum subframe (that is 50% lighter than steel equivalents), which was reinforced with 500 grams of HexPly® prepreg and tested by Saint Jean Industries. The part demonstrates a significant reduction in noise, vibration and harshness (NVH). Other benefits include lower production costs, energy savings, increased driver comfort, production flexibility and part count reduction. With this technology Hexcel is a finalist in the JEC Innovation Awards 2019 in the Automotive Applications category.

HexPly® prepreg patch technology was also applied to a hybrid side sill demonstrator developed with Volkswagen and Dresden University to address future crash test requirements, specifically for electric cars. Combining fiber-reinforced plastic (FRP) with metal, the hybrid construction allows for optimum performance including weight savings, enhanced safety, increased energy absorption, battery protection in a crash situation and production flexibility.

Hexcel will also display a lightweight CFRP transmission crossmember produced from Hexcel’s high performance HexMC®-i 2000 molding compound. The transmission crossmember was developed in partnership with the Institute of Polymer Product Engineering (at Linz University), Engel and Alpex. As the part connects the chassis together and supports transmission it has to be stiff and strong, resisting fatigue and corrosion. Hexcel’s HexMC®-i 2000 was selected as the best-performing molding compound on the market, curing in as little as two minutes to produce lightweight, strong and stiff parts.
To produce the transmission crossmember HexMC®-i 2000 preforms are laid up in Alpex molds and compression-molded in a v-duo press that was tailored for the application by Engel. Ribs, aluminum inserts and other functions can be molded into the part using the single-stage process, reducing component-count. Any offcuts from the preforms can be interleaved between the plies of material to provide additional reinforcement in key areas - meaning that the process generates no waste.

Other Automotive promotions on Hexcel’s stand at JEC World include a composite leaf spring manufactured by ZF using HexPly® M901 prepreg. In contrast to steel leaf springs, composite versions offer many advantages including weight savings of up to 70%, high corrosion resistance, optimized system integration and superior performance. HexPly® M901 prepreg reduces the cure cycle to below 15 minutes and provides 15% higher mechanical performance, with enhanced fatigue properties. It also operates at high temperatures, providing a Tg of up to 200°C following a post cure.

Marine Innovations

Hexcel has a comprehensive range of products aimed at racing yacht and luxury boat builders that include America’s Cup, IMOCA class and DNV GL-approved prepregs, woven reinforcements and multiaxial fabrics for hull and deck structures, masts and appendages.

At JEC World Hexcel will display an IMOCA yacht mast manufactured by Lorima using HexPly® high modulus and high strength carbon fiber prepreg from Hexcel Vert-Le-Petit. Lorima is the exclusive official supplier of masts for IMOCA 60 class racing boats.

Hexcel’s HexTow® IM8 carbon fiber has been selected as the highest performing industrial carbon fiber on the market and will be used by spar and rigging manufacturer Future Fibres to manufacture their AEROrazr solid carbon rigging for all the teams in the 36th America’s Cup.

Hexcel’s HiMax™ DPA (Dot Pattern Adhesive) reinforcements are non-crimp fabrics supplied pre-tacked, allowing multiple fabrics to be laid-up more easily in preparation for resin infusion. Providing an optimal, consistent level of adhesion, they allow a faster and more consistent resin flow, as well as eliminating the use of spray adhesive for a healthier working environment and lower risk of contamination. Simply unrolled and applied to the mold or core layer before the introduction of resin, HiMax™ DPA fabrics are widely used in boat building, where lay-up times can be reduced by up to 50%.

Wind Energy Innovations

Hexcel has developed a range of HexPly® surface finishing prepregs and semi-pregs for wind turbine blades and marine applications. Providing a tough, durable and ready-to-paint surface without using in-mold coats, these products shorten the manufacturing cycle and reduce material costs. HexPly® XF2(P) prepreg is optimized for wind blades and has a ready-to-paint surface, straight from the mold, saving at least 2 hours of takt time.

Polyspeed® pultruded carbon laminates were developed for load-carrying elements in a blade structure and are manufactured with a polyurethane matrix that provides outstanding mechanical performance in terms of stiffness and durability. The blade manufacturing process is optimized, with increased throughput. The pultruded laminates are supplied in coils as continuous cross section profiles.
HiMax™ non-crimp fabrics using E-glass, high modulus glass and carbon fibers are also available in a wide range of unidirectional, biaxial and triaxial constructions. HiMax™ fabrics have applications throughout the turbine, from the stitched carbon fiber UDs used in the main structural elements, to glass fabrics and hybrids for blade shells and nacelles. There are also specialist applications such as lightweight fabrics for heated leading edge de-icing zones.

Most of the composite structures for aircraft are made of carbon-epoxy composites, which can withstand a maximum service temperature of 130°C. As a consequence, carbon-epoxy materials cannot be used in hot zones like engine vicinity areas. The Aeronautical Development Agency (ADA) and CSIR-NAL took up the challenge of developing high temperature resistant composites for use in hot zones of light combat aircraft, which would result in significant weight and cost savings, as well as a considerable reduction in the meantime between failures (MTBF) due to thermal ageing.

The first task was to choose a material system with a service temperature of about ~ 200°C. During the material selection process, it was found that BMI resins are a relatively young class of thermosetting polymers. Hence, a carbon-BMI prepreg was selected due to a number of unique features including excellent physical property retention at elevated temperatures and in wet environments.

It was realized that weight savings and performance can be maximized using co-curing technology. This results in a large reduction of fabrication cycle times, costs and weight. Co-cured structures have fewer fasteners, which results in shorter assembly cycle times and also reduces sealing issues.

A prototype engine bay door assembly was built and tested at 180°C for flight certification. The engine bay door consists of an inner skin and co-cured outer skin assembly with eight transverse stiffeners. The stiffeners were designed with ‘J’ sections. The door size was 1.5 m length, 1 m width and 0.4 m overall depth. The co-cured door was developed using autoclave moulding. Two doors were installed in prototype aircraft and successfully flown.

Aachen researchers have developed the adaptive textile facade green.fACade, which was presented on 2^nd August 2018 in the Aachen Faculty of Architecture of RWTH Aachen University, Germany. green.fACade is installed in front of a building like a second skin and can permanently reduce nitrogen oxide pollution in cities.

The researchers achieve the reduction of harmful nitrogen oxides (NO and NO2) by coating the facade with titanium dioxide. Titanium dioxide acts as a photo catalyst and enables the oxidation of nitrogen oxides to form washable nitrate (NO3-). Since the facade is also greened, it contributes to the conversion of carbon dioxide into oxygen by photosynthesis. In addition, a green facade creates an optical resting point in the cityscape and reduces urban heat through evaporation cooling. The enclosed pictures demonstrate how the introduction of green.fACade can have an effect. Picture 1 shows the Aachen Central Bus Station after, picture 2 before the possible introduction of green.fACade.

green.fACade is part of the innovative research project "adaptive textile facades", which uses the special properties of textiles. Thanks to its design, textiles can let sunlight and air through, thus contributing to a modern, aesthetic building design. A new feature of the research project is that further elements such as the titanium oxide coating or sun protection elements are integrated into the textile facade and placed in front of the existing building facade. The adaptive textile facade acts independently and thus reduces energy consumption through the positive climatic effects on the building facade.

"Adaptive Textile Facade" is part of a current research series with the aim of developing innovative facade constructions that are climate-neutral and increase the comfort of local residents. The research team consists of the three RWTH fields of architecture (Faculty of Architecture, PhD student architect M.Sc. Jan Serode), medicine (University Hospital RWTH Aachen, Clinic for Ophthalmology, Prof. Dr Walter) and textile technology (Institut für Textiltechnik, Prof. Dr Gries) and was able to contribute its expertise in the best possible way.

This summer the research team was supported for the first time by the Munich architectural office Auer Weber, represented by managing director Philipp Auer: "For us architects, developments in the field of textile outer shells are a special challenge. Here, highly developed textile materials and processing methods are combined with the lightness and grace of fabrics. Adaptive textile facade elements will increasingly turn the "building shell" into a "building skin", a system that not only offers weather, heat and sun protection, but is in constant intelligent exchange with its environment".

The great importance of these topics for the public was documented by the presence of Kirsten Roßels, representative of the Department of Economics, Science and Europe of the city of Aachen.  Ms Roßels explains: "As the city of Aachen, we are delighted with the innovative and future-oriented project ideas that are being developed at Aachen University, such as the adaptive textile facade. These developments underline the importance of Aachen as a city of science and I would appreciate it if these and other technologies could also become visible in Aachen in the future".

Prof. Dr Gries from the Institut für Textiltechnik sums up: "As textile researchers, we see a great opportunity to develop concrete solutions for our urban living spaces together with renowned experts from other disciplines. I'm sure we can make the urban climate more pleasant and reduce pollution."

As the countdown to the 2018 edition of Cinte Techtextil China enters its last two months, the final exhibitor line-up is starting to take shape.
