From the Sector

Textile innovator Devan Chemicals will launch two new technologies at the upcoming Techtextil show in Frankfurt (May 14-17). Bio-flam, a bio-based flame retardant product and Odour Breakdown, a wash durable, non-biocidal odour control solution.
As tradition goes, every two years Devan participates in Techtextil, the leading international trade fair for technical textiles and nonwovens. In the quest for sustainability and transparency every company faces these days, the new Devan technologies offer answers to product developers and portfolio designers.

Bio-flam
Some facts & figures: There are at least 5000 fire incidents each day in the EU. Yearly, about 70 000 people are hospitalised with fire-related injuries. Fires cause pollution. So sustainable fire performance of products is an economic, environmental and human necessity. Take the example of mattresses: tests indicate that when on fire, non-FR treated products give less than 5 minutes escape time. Unfortunately, that is not enough time for the fire brigade to arrive. Needless to say that to increase escape time, to reduce the risk and to save lives, products need to be flame retardant. The challenge is to obtain flame retardant properties in the most natural way, to find the right balance between safety for the people and for the planet.

Companies can do this by replacing raw materials from a non-renewable source, by bio-based FR treatments, which are made from renewable sources and do not contain halogens or heavy metals, as described in the norm EN 16785 1:2015. Bio-based FR treatments, like Bio-flam, are made from renewable, vegetable sources and enable the FR treated products to be biodegradable. The active components are 100% halogen- and heavy metal-free. A welcome innovation for the bedding industry, as the European Commission requires mattresses to be recyclable by 2030 in order to reduce landfill.

Bio-flam P307 is the first introduction in the new Devan BIO-FR family, and is biodegradable and is developed to be used on 100% cotton or cotton/viscose mixtures, in order to create an ecological concept, safe for people and planet, whatever might happen. Bio-flam P 307 is developed for mattress ticking to pass EN 597 1&2. The Devan researchers are developing other bio-based products for other market segments and for other fire standards.

imogo is a new Swedish company formed by a team with long experience in textile processing technology. It is now boldly aiming to change the face of the textile manufacturing industry with its new Dye-Max spray dyeing technology, to be introduced to the market at ITMA 2019 in Barcelona.

While still at the prototype stage, and with a first full-scale line currently under construction and due to be demonstrated this Autumn before delivery, the DyeMax nevertheless promises to slash the use of fresh water, waste water, energy and chemicals by as much as 90% compared to conventional jet dyeing systems.

Spray cassettes
Its application unit consists of a closed chamber containing a series of spray cassettes with precision nozzles for accurate and consistent coverage, in combination with the patented imogo pro speed valve that controls the volume to be applied. The chamber is equipped with an exhaust system and droplet separator to ensure that the environment around the unit is free from particles.

“The spray cassettes are a key part in the Dye-Max line,” explains Imogo’s founding partner Per Stenflo. “There is one set of spray cassettes for each of the three separate dye dispersion feed lines and they can be easily exchanged without the need for tools in less than a minute. This allows for extremely fast changeovers between different colours without the need for cleaning. And because the spray cassettes are removable, all maintenance can be performed off line. 
After applying the dye dispersion the fabric is rolled onto a shaft and moved to the autoclave for deep dye fixation via heat and pressure.”

The savings in treatment water the Dye-Max achieves are due to the extremely low liquor ratio of 0.5 litres per kilo of fabric Stenflo adds. 

“At the same time, the low liquor ratio and the spray process require considerably less auxiliary chemistry to start with, and all of it is used in the process, which also greatly reduces the production of waste water, with only 20 litres being required for wash at changeovers. The low liquid content in the fabric meanwhile minimises the energy needed for fixation.”

The Dye-Max has a working speed of up to 50m/min with the practical speed determined by the fabric weight and application volume. 
 

At the Texprocess trade fair in Frankfurt/Main, Germany (May 14th to 17th 2019) VEIT Group will present on more than 400 m² the latest highlights in the areas of ironing, finishing, pressing and fusing in the garment industry as well as automotive and interior sectors.

"Pressing for Excellence" is the corporate slogan of the VEIT Group. In addition, this year's motto at Texprocess is "LOVEIT" which is a wordplay on "love it" or “love VEIT”. In the words of VEIT Group President Günter Veit: “Our motto stands for the passion that we have for the engineering of our products, our love of perfection and our devotion to our customers. This is the basis of their trust in our products. We want to offer our customers value not only now, but also for the future which we believe will be more digital and more sustainable. Both Industry 4.0 readiness, as well as the good of operator and environment are essential components of our product development efforts.”

Among the large portfolio of high-performance technology presented at the trade show, there is a significantly improved shirt finisher SF 26. With the new model SF 26, VEIT manages to further increase both the functionality and the ergonomics of the shirt finisher. For the customer, this optimisation in application technology is reflected in higher quality of the finished product and simplified operation.

Combined with the improved FS shirt folding table series – a highly successful product – VEIT offers true streamlining potential while maintaining high quality levels when folding shirts, blouses and polos in 3 versions.

Reacting to the customers’ demands, VEIT has equipped their popular BX fusing machines – BXT, the universal solution for shirts and outerwear – with a separate feeding belt and a 7” colour operating panel. These changes make the BX fully industry 4.0 ready and helps to further improve the ergonomics and energy efficiency.

In order to increase flexibility in the shaping of textiles, VEIT will present a new solution for high-quality finishing of the elbow seam in the area of BRISAY machines – the BRI 860 VC sleeve seam finish pressing machine. The 8430 universal multiform finisher was enhanced to cover an even wider range of applications. It can now also be used for finishing, among other items, also polos, T-shirts, blouses, blousons and jackets.

In addition to the innovative machine highlights, VEIT has also developed special solutions for customers' investment decisions. "More and more companies that are making investments are not only looking at the purchase price, but rather at the total lifetime cost of ownership," explains Vice President Christopher Veit. VEIT is presenting two interesting offers to meet this trend:
Customers may choose to buy a machine according to the “Pay Per Piece” system, which means that they pay for how much the machine is used, instead of a full up-front investment. This reduces the investment risk and allows more flexible reactions to especially to scalable business opportunities. Alternatively, when purchasing a machine the traditional way, customers can limit operating costs, extend the machine’s lifespan and achieve improved machine availability by signing a service contract. With its global service and partnership network, VEIT Group can offer this service worldwide.

The innovative technology addresses the growing need for on-demand textile design and production

Kornit Digital, a global market leader in digital textile printing innovation, has announced the introduction of the new Kornit Presto, the only industrial single-step solution for direct-to-fabric printing. The Kornit Presto solution eliminates the need for pre and post treatment of fabric and allows for high-quality printing on a broad variety of fabric types and applications. The Kornit Presto does not consume water in the printing process, making it a environmentally friendly solution.

The new Kornit Presto comes with the NeoPigment Robusto, a Pigment-based ink. Implemented into the Kornit NeoPigmentTM process, the Robusto provides above industry standard wash and rub results and exceptional color fastness across a wide fabric and application range. The Robusto enjoys faster physical and chemical bonding characteristics, enabling a significantly shorter curing time, while providing quality and a wide color gamut.

The Kornit Presto solution suits a wide range of business and application needs in a variety of industry segments, including fast growing segments within the on-demand fashion and home décor markets. It is a highly productive solution, available in multiple configurations and able to print 450 square meters per hour.

Gart Davis, CEO at Spoonflower, the world’s first web-based service for custom, on-demand fabric and design creation and a long-time Kornit customer, commented, “We were thrilled to be able to test the new system and found the Presto to be in a class by itself; it prints beautifully on all kinds of fabrics, in a single-step, with an environmentally friendly dry process, and now at a multiple of productivity.  Our partnership with Kornit continues to be fundamental to our mission to make custom fabric accessible to designers, creative individuals and small businesses all over the world. We can’t wait to get going.”

• essenscia Innovation Award is Belgium’s most prestigious prize for industrial innovation
• UltraBond is a cost-effective solution for fully recyclable, latex-free, sustainable carpets
• Significant reductions in ecological footprint and cost for carpet manufacturers

Beaulieu Fibres International, Europe’s largest producer of polyolefin fibres, was nominated for the 2019 essenscia Innovation Award for its recently introduced UltraBond fibre.

The biannual award is the most prestigious prize for industrial innovation in Belgium. Created by essenscia, the Belgian Federation for Chemistry and Life Sciences industries, it aims to promote innovations in the Belgian industry and encourages companies to invest even more in innovative and sustainable products and applications. During the evaluation of the nominated innovation projects, the jury assesses their link with chemistry, life sciences and materials, their contribution to sustainable development, their intellectual property management strategy as well as their added value for the economy.

Formally introduced in early 2019, UltraBond is a patented polyolefin bonding staple fibre that eliminates the need for latex or other chemical binders to bond nonwovens. It enables carpet manufacturers to create 100% PP needlepunch carpets that meet the same performance requirements as traditional constructions, while also reducing end-of-life environmental impact.

UltraBond helps manufacturers make a significant contribution to the circular economy through the production of 100% recyclable carpets. In addition to making recycled PP available for the plastics production chain and reduced waste generation, their total lack of water use and reduced energy use result in significant environmental advantages and financial savings. 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 to the tune of a 35% reduction in CO2 emissions during the full production process.

• Challenging market environment due to low prices for standard viscose, less favorable exchange rates and higher raw material and energy prices
• Very positive development of specialty fiber business with revenue share exceeding 45 percent
• Dividend proposal of EUR 3.00/share plus a special dividend of EUR 2.00/share
• Results for 2019 expected at about the level of 2018 despite a significantly more demanding market environment

The Lenzing Group’s business developed well in the 2018 financial year. A significantly more challenging market environment led to a decline in revenue as well as earnings compared with the record results of the previous year. This was primarily caused by lower selling prices for standard viscose, exchange rate effects as well as higher raw material and energy costs.

• 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.

Michelman, a global developer and manufacturer of environmentally friendly advanced materials, including sizing for glass and carbon fiber, has invested in the FIMATEST adhesion measurement system to ensure their sizing solutions continue to contribute to enhanced performance of composite parts.
