From the Sector

• First fiber producer to have an approved science-based target – CO₂ neutrality by 2050
• Breakthrough in REFIBRA™ technology – worn textiles can also be used as fiber raw material
• Pioneer in the introduction of blockchain technology for fiber recognition
• On track to meet all sustainability targets

Lenzing – Just ahead of the “Day of Forests ” on March 21, which the FAO (Food and Agricultural Organization of the United Nations) introduced in the 1970s in response to global deforestation, the Lenzing Group presents its Sustainability Report 2019. This sets out how the company is actively dealing with the global challenges.

Lenzing produces fibers from the renewable raw material wood and is well known among its customers and partners in the global textile and nonwoven fabric industry for the clear position it takes as a sustainable producer. It is no accident that the new report is appearing on the International Day of Forests. Lenzing’s sustainable practices in procurement, especially for wood and pulp, were once again ranked as leading in the 2019 reporting year (Hot Button Report).

“Stand up! A gainst business as usual ”

Under the motto “Stand up! Against business as usual ”, Lenzing emphasizes its wider responsibilities over and above its products. Business - as - usual scenarios have to be overcome, in particular for climate protection. With a science-based target, Lenzing is taking action to master the problems caused by climate change. The Lenzing Group is committed to reducing its greenhouse gas emissions per ton of product by 50 percent by 2030 (baseline: 2017). The Science-Based Target s initiative has approved Lenzing’s climate target as science-based.

Breakthrough in REFIBRA™ technology

One of Lenzing’s strategic principles under its “Naturally positive” sustainability strategy and a focus in the 2019 Sustainability Report is the circular economy. To address the enormous textile waste challenges of industry and society, Lenzing has developed a unique recycling technology branded REFIBRA™. This technology enables garment production waste to be reprocessed into fibers. 

Kelheim’s premium tampon fibre Galaxy® has proven effective in sanitary pads: It can substitute up to 70% of the synthetics in ADL (Acquisition-Distribution-Layers) in feminine hygiene pads. The amount of feminine hygiene waste is enormous – and often the time it takes for these products to degrade is hundreds of years longer than the lifespan of the woman who used it, because the synthetic components are not bio-degradable. Changing consumer behavior drives the need for environmentally friendly yet safe alternatives.

The viscose hygiene fibres from Kelheim offer significant ecologic advantages: they are made from cellulose, which means they are based on renewable wood and they are fully biodegradable. These fibres are manufactured exclusively in Germany, in one of the most environmentally friendly plants worldwide.

Galaxy® in sanitary pads offers not only a benefit for the environment. Due to its excellent wicking and absorption capacity it conducts liquids quickly and efficiently away from the body and leaves a pleasant feeling on the skin – in other words, it does exactly what the ADL layer is made for. In addition, Galaxy® helps to distribute the liquid evenly in the absorbent core enhancing so the overall performance of the pad.

“Plastic must disappear from these single-use products. The substitution of single synthetic components in sanitary pads is the first step”, says Dominik Mayer from the Bavarian fibre expert’s R&D team. “Down the road we want to offer a completely bio-based solution for sanitary pads and for various other hygiene applications.

Monforts Textilmaschinen GmbH & Co. KG will be providing information on its extensive range of coating and finishing technologies for the production of nonwovens and technical textiles at the forthcoming Techtextil India exhibition.

“India is already a very important market for Monforts and there are exciting prospects ahead for Indian manufacturers of technical textiles, who are well positioned to capitalise on growth opportunities,” says Monforts Head of Denim Hans Wroblowski, who will be at the Monforts stand in Hall 4, booth C52 at the show. “India has one of the largest working-age populations in the world and a complete textile value chain for both natural and synthetic fibres.”

In addition, he adds, India’s government, through its Ministry of Textiles, has been actively promoting the growth of technical textiles through various programmes based on investment promotion, subsidies, the creation of infrastructure and the stimulation of consumption.

As a result, India’s Ministry of Textiles is forecasting that the growth of technical textiles in the country will be over 18% annually in the next few years, from a value of US$16.6 billion in 2018 to US$28.7 billion in 2021.

Value addition

High value-added technical products such as wide-width digital printing substrates, carbon fabrics for high-performance composites, filter media, flame retardant barrier fabrics and heavy-duty membranes are now being coated on Monforts texCoat ranges and finished with the company’s industry-leading Montex stenters.

“Since we acquired the technology that our coating units are based on in 2015, we have made a lot of refinements,” says Hans. “All of these developments are reflected in higher coating accuracy and the resulting quality of the treated fabrics. At the same time, our latest multi-functional coating heads offer an unprecedented range of options, with a wide range of modules available.”

The texCoat user interface is now equipped with the unique Monforts visualisation system and the magnetic doctor blade has greater power reserves. Options include a carbon fibre-reinforced composite coating drum with a more scratch-resistant surface and maximum rigidity and remote control which simplifies exact adjustment for the operator.

Montex stenters in special executions are meanwhile ideal for the drying and finishing of both technical woven fabrics and nonwovens and characterised by high stretching devices in both length and width.

“The European-built Montex range of stenters has earned its leading position in the technical textiles market due to the overall robustness, reliability and economy of these machines,” Hans concludes. “Whatever the intended end-product – and we continue to discover potentially new areas in which technical textiles can be utilised all the time – we have the machine specification and know-how to turn ideas into reality. In India we also benefit from the strong sales and service support of A.T.E. Enterprises.”

Texchtextil India takes place alongside World of Composites at the Bombay Exhibition Centre in Mumbai from November 20-22.

Recently, upgrades and retrofits were made available for Oerlikon Barmag ACW-series winders, with which the benefits of the WINGS concept become tangibly close for operators of POY spinning systems equipped with ACW technology. Worldwide, thousands of winders could take advantage of this system upgrade.

In addition to savings in terms of energy, waste and HR, the benefits of the WINGS concept above all include the consistently high yarn quality, making WINGS yarn a winner in further processing. Particularly with regards to its dyeing properties, the yarn is considerably superior to products manufactured using conventional winder technology.

Yarn producers can now also achieve these typical WINGS properties with ACW winders – with a corresponding system upgrade. The ACW WINGS conversion components and ACW upgrades for draw units can be installed as plug-in units in virtually no time at all, hence minimizing system downtimes. Analog to WINGS, the new ACW WINGS draw unit is more compact and also guides the yarn using rollers instead of yarn guides. This minimizes friction for the yarn and the angles of deflection remain the same, which in turn optimizes the yarn tension on all packages.

Already being used in China
The first expansion phase with 96 positions is already successfully operating at Chinese polyester yarn manufacturer Zhejiang Rongsheng. “We achieved excellent yarn values after just four days. The yarns are of AA quality for a full package rate of 98% and a yarn break rate of 0.5 per ton”, summarizes Xu Yongming, Plant Manager at Rongsheng, talking about the upgrade package. “This has allowed us to once again become one of the top manufacturers with our ACW yarns.” A second expansion phase with 88 further positions will follow at the end of 2019.

The conversion package is also particularly interesting as a result of its fast ROI (return-on-investment) of less than one year. ACW WINGS is available for all ACW-type POY / HOY winders for polyester, polyamide 6 and polyamide 6.6.

• Reduction of material usage by up to 50 percent through innovative draping strategy in the production of fibre composite materials

In fibre reinforced plastic (FRP) production, stamp forming is one of the most economical processes for automated large-scale production, e.g. in the BMW i-series. However, the current processes are susceptible to draping errors and a high proportion of waste. An innovative process developed at the Institut für Textiltechnik of RWTH Aachen University, short ITA, can now significantly reduce the scrap rate and reduce the waste rate of high-priced reinforcing textiles, such as carbon fibre textiles, by up to 50 percent. Sven Schöfer from ITA achieved this effect with his work "Development of a textile-based material feed to increase the preform quality during stamp forming of reinforcing layers". On 10 September 2019, he won the third AVK Innovation Prize in the "Research and Science" category at Composite Europe in Stuttgart, Germany.

Current process
In stamp forming, clamping grippers are usually used in industry to feed the stacked individual layers to the forming process and position them on the lower tool via a clamping frame or hold-down device. Due to the clamping grippers, the cutting proportion of cost-intensive reinforcing textiles is high, as additional material at the textile edge is necessary with clamping systems. Other approaches to feeding the reinforcing semi-finished product during forming and simultaneously improving the draping quality are also not economical: they are usually only designed for certain textile cuts, cannot be automated, are prone to errors or are expensive special solutions.

There is currently no system in the industry that can apply retention forces along a final contour with low waste and remains flexible in terms of geometry.

Innovative approach of Sven Schöfer
The innovative process developed by Sven Schöfer works with a detachable textile joint, a so-called tufting seam. It allows the single layers to slide off during the forming process under a retention force dependent on the seam design.

This reduces or completely eliminates draping errors in previously critical areas, even with complex preform geometries. This leads to a significant increase in preform quality and a reduction in scrap rates. The process is also highly efficient, as tensile forces can be applied to any component geometry on near-net-shape blanks. This reduces the material input by up to 50 percent.

A wide range of new technologies will be demonstrated by Vandewiele at the ITMA 2019 textile machinery show in Barcelona from June 20-26, including the latest RCE2+ digital carpet weaving machine.

All Vandewiele technologies are now being equipped for machine-to-machine interaction and learning, as part of the company’s comprehensive TEXconnect programme.

Meeting new industry needs
As a leader in complete carpet manufacturing systems – including BCF extrusion lines, heat setting systems and carpet weaving and tufting machines – Vandewiele has rapidly responded to the evolving needs of the textile industry for smaller and customised production runs, the most challenging of designs, and faster and more sustainable manufacturing.

The company’s sensors, software programmes and servers have become increasingly sophisticated as part of the TEXconnect program, and the real-time data from different machines – across connected manufacturing sites and across different countries and even continents – can be collected and shared. Digital models of both machines and production processes can be created and analysed for the optimisation of production settings, to vastly improve scheduling and planning and also make considerable savings in raw materials and energy consumption.

Virtual and remote control now allows for the Big Data analysis that is propelling the industry forward and will pave the way for AI applications. For carpet manufacturers, all of this is leading to the creation of truly Smart Factories.

RCE2 carpet weaving
The new RCE2+ Rug and Carpet Expert weaving machine is a truly digital workhorse, with all yarns continuously controlled and measured and the difficult bobbin changes of the past completely eliminated. This is as a result of Vandewiele’s latest Fast Creel, with the feed and tension of each pile yarn controlled by individual servomotors.

The pile yarns are now fed directly into the machine without having to pass pile-stop motions, to both increase efficiency and eliminate any waste yarns, while achieving previously unreachable industrial speeds.

The filling enters the machine smoothly via the latest IRO X3 winders, heavy duty filling brakes with multi lamellas, an active yarn recuperator and a high speed weft mixer, where again, all tensions are set electronically. Vandewiele’s servo-driven heddle frames (Smart Frames) are meanwhile already well proven in the industry.

TEXconnect further provides readily-available data on all yarn consumption, tension and threading, and then will supply the predictive maintenance that is paving the way to self-learning carpet weaving machines.

All of this would be unnecessary, if it didn’t result in allowing manufacturers to make the highest quality carpets at the most economic prices ever, with savings on the highest-bulk pile yarns from the Vandewiele extrusion lines, reduced waste yarns in the creel and industrial production speeds that have never before been attained.

Techtextil 2019: Schoeller launches its new finishing technology called NanoSphere® Plus. The special effect of this new development is its protection against fingerprints and greasy stains. Furthermore, even after being absorbed by the fabric stains are quickly and easily wiped away without washing.

Every human being leaves its marks. In particular, on daily-use items that are picked up or touched often. Especially on textile surfaces, hand and fingerprints in combination with dirt and dust particles leave an unpleasant, greasy dirt film, which is very difficult to clean.

NanoSphere® Plus, developed by Schoeller Technologies AG, the business unit for technologies at Schoeller Textil AG, works on the basis of a functional chain. Textiles are equipped with a matrix finish to reduce the capillary effect in the textile’s fibers. Especially unpleasant sebum residues and dirt that are often released by finger and handprints are less absorbed by the fabric and can be easily wiped away.

Beside the excellent protection against finger and handprints, textiles with NanoSphere® Plus are additionally water and oil repellent, abrasion resistant and extremely durable. The finishing technology rarely affects the look or feel of the fabric.

Non-washable textiles that are often touched by hands or fingers, or fabrics that are in direct contact with the skin benefit most from this new technology. Therefore, NanoSphere® Plus is ideal for woven fabrics and synthetic leather or synthetic suede for bags, covers of electronical devices, head phones, loud speakers or other items in the field of interior equipment.

• 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.

PERLON® - The Filament Company presenting will be showcasing PearlTech®, their latest product brand at Techtextil in Frankfurt from 14th – 17th May. PearlTech® is a monofilament which has special particles incorporated into it. The size and shape of the particles is irregular and the material is unrelated to the base polymer.

PearlTech® is currently available in a PET based variant as well as in PA. The particles are added into the polymer melt and evenly distributed over the whole cross-section. These newly acquired properties remain intact throughout the lifetime of the monofilament. The particles incorporated into the polymer matrix protrude slightly from the monofilament surface, giving PearlTech® an interesting optical appearance and a structured surface finish.

PearlTech® provides improved stability against wear, reduces machine power consumption whilst reducing the build-up of dirt on the end product. This is in comparison to standard polymers. The particles have no negative effect on hydrolysis resistance and furthermore offer the possibility to avoid the use of fluoropolymers.

CHOMARAT, the expert in composites reinforcements, is the partner of BABOLAT with its multiaxial carbon, C-PLY™ Hexagonal. Indeed, the specialist racket sports goods manufacturer is launching the new version of the BABOLAT’s Pure Aero. A combination of ultra-modern design and high performance, this tennis racket for champions has made an appearance on the courts of the Rolex Paris Masters. “We are very proud to be chosen by BABOLAT. Our new carbon reinforcement, added to the heart of the racket, enables better control and makes each shot more precise and stable,” says Pascal JOUBERT DES OUCHES, Sports Equipment Market Director at CHOMARAT.

C-PLYTM HEXAGONAL, THE PERFECT ALLIANCE OF PERFORMANCE & DESIGN
The addition of C-PLY™, CHOMARAT’s multiaxial carbon reinforcement, to the core of the BABOLAT’s Pure Aero has increased the racket’s stability while enhancing its performance. The specificity of the reinforcement lies in its stitching thread. “This unique thread brings out the color of the resin pigments because it has been designed to remain visible after its impregnation. It also contributes to extra reinforcement and an exceptional design!” concludes Pascal JOUBERT DES OUCHES.
