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. 
 

Sappi launches a sublimation paper optimised for glue-belt printers
The rapid individualisation and personalisation of fashion and home textiles on polyester-based materials using sublimation transfer is in high market demand. With this in mind, Sappi is expanding its portfolio of dye sublimation papers: with its silky-smooth reverse side, the Transjet Drive sublimation paper innovation enables better runnability on digital high-speed printers with a glue-belt system. This smooth printing performance increases productivity. Moreover, due to its low grammage, Transjet Drive offers weight per unit area advantages.

The new sublimation paper is specifically designed for glue-belt printers, but is also suitable for high-speed printers without a glue-belt system. Due to its specially treated reverse side, it adheres to the printing belt without slipping and can pass through quickly. The smooth reverse side also ensures that the paper does not stick to the adhesive-belt and that it slides away without leaving any residue on the belt. These special properties protect the glue-belt and save work steps such as cleaning or corrections during production. With grammages of 45 and 55 g/m², Transjet Drive also offers weight advantages. Here is another reason why this new product is attractive to customers: every ton of Transjet Drive gives you more printable paper area compared to heavier grammages.

On the surface, the paper is specially coated, so that the ink dries quickly and the final result on the textiles appears very colour-intensive. Thanks to fast drying, the webs can be rolled up again immediately after printing. Because of these properties, Transjet Drive is used especially for fashion and home textiles such as scarves, bed linen and curtains. The 55 g/m² version is also suitable for soft signage.

• New game-changing Kornit NeoPoly Technology with industry-first innovation for industrial polyester printing that prevents dye migration.
• New Kornit Avalanche Poly Pro system unveiled at events during April, commercially available immediately.

Kornit Digital Ltd. (NASDAQ: KRNT), a global market leader in digital textile printing innovation, unveiled the game-changing Kornit NeoPoly Technology, which is the industry’s first digital, industrial process for high-quality printing on polyester.

Polyester is the second largest category in the overall T-shirt market, it is key in the sport segment, and is growing in the athleisure and functional apparel segments. Currently polyester is printed predominantly by analog solutions, which creates major technological, cost and sustainability challenges.  

The new ground-breaking Kornit NeoPoly Technology addresses these challenges with a new process and ink set implemented in the renowned Kornit NeoPigmentTM process. Kornit’s new process handles polyester applications without compromising on design, run size, substrate or labor.

The breakthrough technological innovation is achieved by an innovative ink set and a physical and chemical process specifically developed for low temperature curing, and polyester enhancing functionalities developed to maintain fabric characteristics and provide superior fastness. This unique process prevents dye migration on polyester.  The inks are Oeko-Tex and Eco-Passport certified and do not contain PVCs or other toxic ingredients.

The first system equipped with the Kornit NeoPoly Technology is the new Kornit Avalanche Poly Pro, a member of Kornit’s world-class reliable, highly productive industrial platform. The single-step Poly Pro is the perfect system for the industry, enabling easy and cost effective short-runs and on-demand printing on polyester garments.

This year, AZL won the JEC AWARD 2019 for the development of the new machine system “Ultra-Fast Consolidator Machine”. This innovative machine system is a result of an 18-months AZL Joint Partner Project, conducted in 2017-2018 by the research partners AZL Aachen and Fraunhofer IPT Aachen, in cooperation with industrial partner companies including Conbility, Covestro, Engel, Evonik, Fagor Arrasate, Faurecia SE, Laserline, Mitsui Chemicals, Mubea Carbo Tech, Philips Photonics, SSDT and Toyota (in alphabetical order).

The new UItra-Fast Consolidator Machine offers both high flexibility and mass production of tailored thermoplastic laminates with reduced scrap. Fully consolidated multi-layer laminates with different fiber directions and minimized scrap (tailored blanks) can be produced in cycle times below 5 seconds with this new scalable machine setup. This individualized mass production is accomplished by a combination of laser-assisted tape placement with in-situ consolidation and a piece-flow principle, which is state of the art in the printing industry but has not been used in such a way within composite production. The achievable productivity is enhanced to more than 500 kg/hour by this piece-flow principle with carriers moved through multiple application stations which are equipped with multiple tape placement applicators. The new machine is scalable: multiple application stations can be added, e.g. for each layer one station for mass production or for each fiber direction one station with a carrier-conveyor carousel: here the carriers are moved multiple times through the application stations.

The system will be commercialized by some of the industrial partners in 2019. The real machine setup has been presented at the AZL booth during the JEC Exhibition in Paris 2019.

The follow-up project has just started and is still open to join for industrial partners. This follow-up project comprises a further upscale of the machine system as well as a preparation of the commercialization by long-term durability tests and further process optimizations using different tape materials.

IPC, the Industrial Technical Centre with expertise dedicated to plastic and composite innovation, is presenting two prototypes on its stand: an intelligent motorcycle helmet and a multifunctional windturbine blade. "With these two prototypes, IPC demonstrates its ability to functionalize composites, particularly with printed electronic components. Live demos will be organized during the three days of the show on our booth," explains Bertrand Fillon, General Manager of Research at IPC. The helmet was manufactured in partnership with the technical and creative paper manufacturer Arjowiggins, and the wind turbine blade, with the CEA. These two demonstrators will also be exhibited in Germany at the LOPEC exhibition 2019 in Munich on 20-21 March.

IMPROVE THE USER EXPERIENCE
The objective is to add new features to improve the user experience, without impacting security. The motorcycle helmet is equipped with sensors and NFC communication functions. "Here, printed organic electronics are used in the helmet to allow remote temperature changes," adds Lionel Tenchine, Program Line Manager for "Technologies for Intelligent Products" at IPC. The helmet manufacturing process is based on the use of composites and the infusion process.

DETECTING POTENTIAL DAMAGE IN ADVANCE
Developing predictive maintenance is an important issue when it comes to avoiding sudden, serious accidents. A recent McKinsey study estimates that by 2025 it will save $630 billion for companies, for example. The wind turbine blade presented at JEC World detects potential damage that could occur on the blade structure beforehand, making it possible to carry out preventive repairs on the one-meter-long blade. Printed organic electronics are used in the demonstrator to integrate strain gauges and the temperature detection function.

DOMO Chemicals, a global leader in the field of material engineering will discuss economic and environmental challenges at the 2019 Wood Mackenzie European Nylon Conference in Frankfurt am Main, Germany from March 5 to 7.

Ron Bult, Director of Global Sales of DOMO Engineering Plas-tics will highlight solutions based on ECONAMID®, a family of PA6 & PA66 compounds based on sustainable post-industrial feedstock derived either from film manufactur-ing or from fiber and yarn manufacturing. Depending on the applications and the desired level of physical and mechanical properties, DOMO can provide grades that are unfilled, mineral filled, glass-fiber filled, or carbon-fiber filled.

“DOMO is making major efforts to accelerate the development of sustainable solu-tions that bring value to our customers’ businesses, while acting responsibly towards the environment, employees and communities,” says Bult.

Also at the conference, Philippe Guerineau, VP Sales & Marketing in the company’s Nylon & Intermediates business unit, will join a panel discussion at the conference to discuss on the economic outlook and the future of the polyamide industry. DOMO will be holding consultations and exclusive events for its customers as well.

• 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.
