From the Sector

At ITMA 2019 in Barcelona from June 20-26th, Goller will introduce the new Knit Merc for achieving the highest quality mercerization of knitted fabrics at the lowest tension and with under 3% variation in dimensional stability with high grade fabrics, for perfect dyeing results every time.

Mercerization is an essential textile finishing step for all cotton and cellulosic fibre-based fabrics in order to improve dye uptake and tear strength while reducing fabric shrinkage and imparting a silk-like lustre to the materials.

The Knit Merc is the result of intensive R&D developments at Goller and follows the successful introduction to the market of the company’s Sintensa Cyclone drum washing compartments for achieving the highest washing efficiency at the lowest tension.

The Knit Merc being exhibited at ITMA 2019 can accommodate 8.4 metres of fabric in its impregnation compartment and a further four metres in its first chain section to achieve a production speed of 25m/min at 30 seconds dipping time.

It is designed for dry-on-wet mercerizing, either cold or hot, and is equipped with an inlet combination of scroll and slat rollers for fabric guidance, a Tandematic uncurler in front of a rubberized de-airing roller and a grooved 320mm bottom roller with 320mm and 600mm perforated upper drums.

It benefits from automatic tension regulation and the low liquor content is ensured by the integrated lye tank and automatic circulation and filtration units.

An 8-ton high efficiency squeezer is stationed at the exit before the chain section and a 5-ton squeezer at the exit of the chain field.

Further fabric control and stability is provided by a cast iron pin chain with automatic optical and mechanical sensors, the Tandematic uncurler, an overfeed device and a driven belt arrangement for fabric support.

At home, at work, on the street, in the sky, on the water, even in space, technical textiles and nonwovens are swinging towards ever higher performances in amazing applications. Versatile and light, but sometimes stronger than metal, these materials of the future gain their superpowers from the interaction of precisely coordinated textile systems. At Techtextil in Frankfurt am Main from May 14 to 17, 2019 in Hall 3, B06, Oerlikon will be showing chemical fiber applications made of polyester, polypropylene and Co. and what they can do in these fields. However, these exhibits are only a communicative means to an end, as Oerlikon is primarily interested in placing the associated machinery and plant solutions at the centre of discussions with trade fair visitors.

More than two thirds of all technical innovations are directly or indirectly based on new materials, says the German Research Ministry. One could add: The key to a more advanced world, for technological products with amazing functions, breathtaking performance and greater environmental benefits, is also to improve the properties and processing of materials. This applies first and foremost to textiles. Probably no other fabric is so strong as a "team player" who draws its strength from its cohesion. A single polyester thread, for example, looks inconspicuous. Processed into a thigh-thick special weave, however, high-strength High Modulus/High Tenacity fibers anchor floating oil platforms in the deepest waters. These kilometer-long "Mooring Ropes" withstand a breaking load of well over 1,000 tons and perform their task better than steel. For decades, Oerlikon Barmag has been offering special solutions for the production of so-called industrial yarns (IDY) that are tailored to customers worldwide. "We will once again be presenting numerous innovations at this trade fair to inspire our customers," explains Dr.-Ing. Dipl.-Chem. Roy Dolmans, Technology Manager IDY and R&D Filament Processing.

• 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.

Hexcel is exhibiting at the Aero India show for the sixth time, continuing to support customers in the Indian subcontinent and throughout Asia. This year’s show takes place in Bangalore from February 20-24 (Stand AB2.5D, Hall AB) to promote a range of carbon fibers and composites that are benefiting Indian aerospace manufacturers for commercial aircraft, helicopters and space programs.

To coincide with the show, Hexcel is announcing the opening of its new sales office, Hexcel Composites India LLP. The office is located in Bangalore and will be fully operational in March 2019. Mr Vijay Sharma, Sales Manager, and Mr Ram Kumar, Technical Representative, will manage the sales activities and support key customers in the region.

Hexcel has supplied carbon and glass fiber fabrics, prepregs, honeycombs and adhesives to Indian aerospace companies for more than 28 years, including Hindustan Aeronautics Ltd (HAL), National Aerospace Lab (NAL), Indian Space Research Organisation (ISRO), Vikram Sarabhai Space Centre (VSSC) and TATA Advanced Materials.

Hexcel’s high strength and intermediate modulus carbon fiber range has been augmented by the launch of HexTow® HM63, a high modulus carbon fiber that has the highest tensile strength of any existing HM fiber. HexTow® HM63 provides outstanding translation of fiber properties in a composite, including superior inter-laminar shear and compression shear strength. HexTow® HM63 is therefore ideal for any high stiffness and strength-critical applications including space, satellites, UAV, commercial aerospace and helicopters.

At JEC World 2019, Sika Advanced Resins will unveil Ullit’s new composite tank for trucks that run on compressed natural gas (CNG).

Together with its tailor-made epoxy system designed by Sika Advanced Resins, who are a leader in the development and production of high-performance resins, the tank helps to reduce pollution in urban traffic.

An epoxy laminating system that adapts to different designs
The tank, which contains up to 320 liters is the same size as a conventional diesel fuel tank. "We have been innovating together for more than 10 years! Sika Advanced Resins has developed a specific resin for our new range of high-pressure tanks. This high-performance resin can be adapted to all design constraints, particularly for our very high-pressure hydrogen tanks, up to 700 bar," explains Ullit founder and CEO Claude Hembert.

Sika Advanced Resins has used its expertise to develop a tailor-made resin to withstand the cyclic pressurization loads on the filament-wound tanks. In combination with carbon fiber the resin provides mechanical resistance for different tank shapes including those for vehicles running on natural gas. "The tank is placed in the same place as a diesel fuel tank and avoids the need for transformations in trucks. In addition Ullit-Sika composites reduce the weight of the tank by a factor of four, a huge benefit when we estimate that one tonne saved on a truck saves four liters of fuel per 100 kilometers in urban traffic," explains Patrick Noirclerc, Local Expert Composites at Sika Advanced Resins.

• Latex-free: UltraBond allows 100% recyclable thermal bonded nonwovens
• Sustainability & cost-efficiency: significant reductions in CO2 emissions and energy and water consumption for manufacturers of needlepunched exhibition & contract flooring
• UltraBond debuts at Domotex 2019 Stand B56 Hall 11

Beaulieu Fibres International (BFI) unveils a unique opportunity for carpet manufacturers to create fully recyclable needlepunch carpets, and benefit from production and resource savings, without influencing performance.

Launched at Domotex 2019, new UltraBond is a patented polyolefin bonding staple fibre that eliminates the need for latex or other chemical binders to bind nonwovens. It opens up a new path for creating 100% polypropylene (PP) needlepunch carpets which meet the same performance requirements as traditional latex-bonded carpets while reducing the end-of-life environmental impact. Functional properties such as pilling resistance, resistance to wear and abrasion, and also UV resistance are guaranteed.

Using UltraBond manufacturers finally gain the potential to cost-efficiently produce 100% recyclable carpets. In addition to the general benefits of making recycled PP available for the plastics production chain and reduced waste generation, environmental advantages and financial savings arise from a total lack of water and less energy use. As a 100% dry process, thermal bonding uses no water and results in a total absence of waste water. There is also a reduction in the VOC level of the carpet. This all leads to a significant reduction in a needlepunch carpet’s ecological footprint.

The sustainability benefits are quantified through lifecycle analysis (LCA) of an exhibition carpet application – among the primary applications for needlepunch carpets. Evaluations show that the absence of water consumption directly translates into a large energy saving of 93% when using UltraBond compared to a latex bonding solution, and also a potential annual water saving of over 20 million litres for 100 million m2 of exhibition applications in the EU. Without the addition of any other bonding agent, CO2 emissions are reduced by 35% over the full production process.

Karena Cancilleri, Vice President Beaulieu Engineered Products, Beaulieu International Group, commented, “Recyclability and achieving a greener, more cost-effective production process without compromising on current performance levels are significant unsolved topics within today’s carpet industry. By eliminating the need for latex and chemical binders through UltraBond, we offer needlepunch manufacturers a breakthrough they have been looking for that boosts environmental and economic sustainability. We see textile flooring as just the beginning. Together with our customers, we look forward to exploring the potential of this unique thermal bonding fibre in other applications such as laminated nonwovens or as an alternative to dry powders.”

Discover more about UltraBond from the Beaulieu Fibres International team at Stand B56 Hall 11, Domotex 2019 in Hannover, Germany from January 11-14, 2019.

A new important partnership marks the path of Itema towards a greener future for the whole denim production chain. Prosperity Textile, one of the main denim producers worldwide, has chosen for its new facility one of the most interesting and sustainable-oriented Itema technologies, iSAVER™ equipped on the Itema R95002denim. Prosperity Textiles is, in fact, one of the early adopters of this new technology chosen for the new plant that the world-famous indigo fabrics producer will open in Vietnam, and that will be exclusively equipped with the latest Itema weaving machine model, demonstrating once again its green, future-oriented approach.

Thanks to its partnership with Itema, Prosperity Textiles makes again a step forward in terms of sustainable innovation, as one of the first denim producers able to successfully turn - even the weaving production - green. A partnership that is planned to be showcased in some of the most important textiles exhibitions worldwide focusing on Asian and denim markets. A path that starts with KingpinsShow, Amsterdam (October 24-25) where the Chinese denim producer will put into the spotlight this brand-new solution aimed at further increasing the eco-driven approach of the company; an important appointment is also in the Itema calendar: the ITMA Asia + CITME 2018 exhibition, Shanghai (October 15-19) where the Italian company showcased the important green step-forward in denim weaving processes and the full range of its innovations.

iSAVER™: the ideal green tool for denim weaving
This new technology, developed by ItemaLab™, the Itema Advanced Innovation Department, isable to completely eliminate the left-hand weft waste, allowing to insert the weft yarns in the fabric without the need of additional yarns. iSAVER™ significantly reduces raw material waste, leading to tangible benefits in terms of machine’s efficiency, cost reduction and energy saving.

Just consider that the weaver will gain a minimum saving of € 2.000 per year per machine, and our planet will gain even more. In fact, for the first time in the weaving industry, a sustainable approach when choosing the weaving equipment is now possible. Thanks to iSAVER™, 1.000 Kg of cotton per machine per year – the 3% of the total raw materials - will be saved, thus avoiding the waste of 20 million liters of water, equivalent to 400.000 showers.

Numbers are clear: the introduction of iSAVER™ clearly sets a new benchmark in terms of sustainability within denim fabric production. Furthermore, the iSAVER™ is one of the key features of the Itema R95002denim, the rapier weaving machine born and designed to weave denim guaranteeing to weavers superior textile quality, outstanding user-friendliness and tangible energy and raw materials saving.

A joint eco-driven path
Itema, understanding very well the importance of saving resources and energy to drive the textile production in the direction of a more conscious manufacturing, focused its attention to develop breakthrough weaving solutions and in 2018 introduced to the market the iSAVER™, a revolutionary device dedicated specifically to denim fabrics able to eliminate the waste selvedge on the left-hand side of the fabric.

This is one of the reasons-why Prosperity Textiles has chosen to adopt this extraordinary technology for its new facility. Today Prosperity Textiles is one of the main denim producers worldwide, counting 1,300 employees and 20 offices worldwide. Moreover, a second state-of-theart denim mill will be inaugurated in Vietnam by the end of 2018.
What makes Prosperity able to stand out on a global scale, is not simply its products high quality but the ability to conciliate flawless denim fabric production with a sustainability-oriented mindset that permeates every stage of their textile supply chain.

Prosperity, indeed, adopted innovative green manufacturing concepts through all stages of the company’s operations, from product development, raw materials procurement and processing, to natural resources and energy utilization including waste management. Prosperity’s denim production is based on the employment of best quality yarns available on the market, while still targeting the most sustainable sources, from BCI to organic, recycled cotton, and from Tencel™ Lyocell to Sustans™, in 2017, more than 20 million yards fabric sales from Prosperity are with sustainable fibers inside.
The introduction of eco-friendly dyeing and finishing practices allows the company to create beautiful indigo shades and performance denims, with less water and energy consumption compared to the traditional systems. Last year, Prosperity produced 20% more fabrics than 2016, yet the water and electricity use and greenhouse gas emission was down by 11.5%, 7.9% and 5.4% respectively.

In this continuous process of improvement and contribution to a greener industry and planet, plays a central role the recent renewal of the historic partnership and strategic alliance with Itema – the leading manufacturer of cutting-edge weaving solutions – which represents the natural evolution of a constant process of research for partners able to support Prosperity Textiles’ growth as a sustainable company.
Up to now, all innovations and efforts done in this regard addressed the traditionally more polluting steps of the denim production. In fact, if the development of green technologies is nowadays spread in many fabric processing stages, such as finishing and dyeing, weaving was not yet capable to provide sustainable solutions to weavers.

Because aircraft engine noise contributes to environmental noise around airports and populated cities, the aerospace industry has been working on new aircraft designs that will emit less noise so they can meet the ever-increasing requirements imposed on the industry to reduce noise pollution. Shielding and absorbing aircraft engine noise at the source represents one of the most effective ways to address this issue.

Hexcel, a global leader in advanced composite technology, has been at the forefront of acoustic technology development with its Acousti-Cap® broadband sound-reducing honeycomb, which enables engine designers to reduce the noise from takeoffs and landings yet without adding significant weight to the aircraft.
 
“Hexcel has continued investing in the evolution of Acousti-Cap® product technology to improve performance and reduce cost,” said Imad Atallah, Group Product Manager for Honeycomb at Hexcel. “Collaboration with industry leaders, including NASA and Boeing, has been key to that development,” he added.
 
The 2DOF (Two Degrees of Freedom) honeycomb core acoustic liner was introduced in 2008 and was subsequently adopted and installed on the Boeing 787 Dreamliner inlet, the Boeing 747-8 inlet and transcowl, and more recently on the Boeing 737 MAX inlet. This success enabled continued technology development and evolution in MDOF (Multi-Degrees of Freedom) where the acoustic septum is inserted in the honeycomb cell at different heights, as well as having two septums in honeycomb chambers. This type of technology allows for improved acoustic attenuation at a broader frequency range, as well as increased absorption.
 
“Hexcel’s Acousti-Cap® technology has shown great performance benefits over competing technologies from the beginning” said Clark Smith, Director of Technology -- Core Products at Hexcel. “We have continued to improve the technology through taking advantage of the single cell treatment concept, by adding capability that the industry was looking for,” he added.   
 
Hexcel’s latest Acousti-Cap® technology was recently tested in a joint NASA-Boeing flight test on a B737 MAX test platform, and the results beat expectations as reported by Aviation Week. Collaboration between Hexcel and NASA over several years on the development of MDOF technology led to the successful test results on this latest flight test.
 
The ability to attenuate a broader noise frequency range and increase acoustic absorption with the Hexcel liner has allowed an optimized design of the overall inlet that reduces drag and improves noise attenuation. Hexcel continues to invest in acoustic liner technology and is proud of the positive results of this NASA-Boeing flight test.
