Following their entry into the fibres and textiles sector, as announced at K 2022, recycling machine manufacturer EREMA launches the INTAREMA® FibrePro:IV - which has been specially developed for PET fibre-to-fibre recycling - at ITMA in Milan from June 8 to 14. Thanks to its especially gentle material preparation and efficient removal of spinning oils, the rPET produced can be reused in proportions of up to 100 percent for the production of very fine fibres.

PET is regarded as a key material for the production of synthetic fibres. Around two thirds of the total volume of PET goes into the production of PET fibres for the textile industry. This highlights the importance of high-quality recycling solutions for the circular economy. By combining proven INTAREMA® technology with a new IV optimiser, EREMA succeeds in processing shredded PET fibre materials heavily contaminated by spinning oils in such a way that the finest fibres can be produced again from the recycled pellets. The system, which now joins EREMA's machine portfolio as the INTAREMA® FibrePro:IV, is characterised by a longer residence time of the PET melt. This is an essential factor for achieving high quality recycled pellets, as it allows the spinning oils and other additives used to improve the handling of the fibres during manufacturing to be removed more efficiently than in conventional PET recycling processes. Following extrusion, by polycondensation the intrinsic viscosity (IV) of the PET melt is increased in the new IV optimiser and under high vacuum to the precise level that is needed for fibre production. "Including filtration the output quality that we achieve with this recycling process is so high that ultra-fine fibres of up to 2 dtex can be produced using these rPET pellets, with an rPET content of 100 percent," says Markus Huber-Lindinger, Managing Director at EREMA. Waste PET fibre from production processes can therefore be further processed into rPET filament fibre, carpet yarn and staple fibre.

While the focus of the fibre and textiles application is currently still on PET fibre recycling, EREMA is committed to driving forward the recycling of mixed fibre materials from classic textile recycling collection in a next project phase. In order to accelerate development work, the EREMA Group opened its own fibre test centre, where a cross-company team is working on recycling solutions for fibre-to-fibre applications. The centre also operates a fully equipped and variable industrial-scale recycling plant. It includes the peripheral technology required and is available to customers for trials.

DiloGroup will be attenting India ITME 2022 (December 8 – 13, 2022), an exhibition for the textile industry, which offers a central forum for dialogue within the textile production sector, including textile machine building, fibre production, ancillaries and accessories. For DiloGroup this event is a good oppportunity to inform customers and interested parties about new developments aimed at improving production technologies with a focus on needlefelts.

Focal points of the development work are:

1. Intense Needling:
   The development efforts of DiloGroup aim at producing nonwovens by “intense needling” instead of water entangling, even for light nonwovens made of fine fibres for the medical and hygiene sector with an area weight of 30 – 100 g/m². This would result in a reduction of the environmentally relevant production costs; per annum to about 1/3 to 1/5 of current.
2. “Fibre Pulp Recycling”
   Fibrous material in nonwovens and particularly used clothes can be successfully recycled, if staple length can be conserved in the tearing process. In the classical tearing process, staple lengths are dramatically reduced and therefore these fibres can only be used as base material for inferior uses in thermal or acoustic insulation or in protective textiles, transportation or protective covers etc.
   When recycling textile waste in the context of the collection of used clothes, the so called “filament-saving” tearing using special tearing machines and methods must be used to produce fibres with longer staple lengths which can be fed to a nonwoven installation. Hence product characteristics can be better specified and controlled.
3. Additive nonwoven production
   The additive production method of the “3D-Lofter” is especially suited for automotive parts with differently distributed masses. It is also suited for uses in the sector of apparel and shoe production.
4. “IsoFeed”-card feeding
   In the field of card feeding, the “IsoFeed” method offers great potential for a more homogeneous card feeding at the same time reducing the variation in cross-machine fibre mass distribution and thus the fibre consumption while conserving the end product quality.

International technology group ANDRITZ will present its innovative nonwovens and textile technologies at the booth of its Indian representative PRN Techtex at Techtextil India 2021 in Mumbai, India, from November 25 to 27, 2021. A special focus will lie on its technologies for air-through bonding, needlepunch, textile recycling, and processes for biodegradable wipes, like spunlace and WetlaceTM.

Air-through Bonding
Air-through-bonding lines are the preferred choice for producing nonwovens with the best quality of softness and bulk for acquisition distribution layers, top sheets, and back-sheet products. With ANDRITZ carding machines and the new flat belt oven, customers benefit from high-performance fabrics from 16 to 80 gsm, produced with bicomponent fibers. Several Chinese customers have already invested in ANDRITZ aXcess carding machines, which provide perfect web uniformity. In addition, the CETI (European Center for Innovative Textiles) in Lille, France, has installed an air-through-bonding oven from ANDRITZ.

Textil-recycling Technologies
Recently, ANDRITZ acquired Laroche SAS, a leading supplier of fiber processing technologies such as opening, blending, dosing, airlay web forming, textile waste recycling, and decortication of bast fibers. The product portfolio further complements and increases the ANDRITZ Nonwoven product range. One focus of this product range lies on complete recycling lines for post-consumer and industrial textile waste to produce fibers for re-spinning and/or nonwoven end uses.

Needlepunch Technologies
Driven by the dynamic market for durable nonwovens, ANDRITZ has developed an elliptical pre-cylinder tacker – the PA3000. With this modern machine, ANDRITZ is responding to customer demands for higher capacities and lighter products. The PA3000 is an optimized cylinder pre-needleloom, which offers greater speeds and widths and has been specially developed for lighter webs. There is no friction between the web and the rolls, and there are no issues with the visual appearance.

ANDRITZ is also focusing on its latest needling technology for producing veloured felts, mainly for applications in the automotive industry.

In addition, ANDRITZ will be presenting the next generation of its batt-forming technology, the ProWin system. ProWin is a further development of ProDynTM and ProWidTM, which have achieved a high level of acceptance on the market with around 200 systems installed. This technology improves the current weight-profiling options and increases the actual production capacity.

Production of Bio-Wipes
For many years now, ANDRITZ has offered different nonwoven processes, such as spunlace and Wetlace, with one goal in mind: reduction and elimination of plastic raw materials while maintaining the high quality of the desired product properties. The latest development in this field is the ANDRITZ neXline wetlace CP line. This is a fully engineered production line, combining the benefits of wetlaid and drylaid technologies to produce a new generation of biodegradable wipes. This process achieves high performance entirely with plastic-free raw materials. The added benefit of using a blend of fibers, like wood pulp, short-cut cellulosic fibers, viscose, cotton, hemp, bamboo, or linen, without chemical additives, results in a 100% sustainable fabric.

• Polynova to gain market share for the GRAFE Group in the Swiss region from November The GRAFE Group, Blankenhain, has found a new sales representative for Switzerland in Polynova Group AG, Risch-Rotkreuz (Switzerland).

The partnership will be officially launched at Fakuma 2021. "Our new Swiss agency specialises in the distribution and production of high-quality technical plastic granulates and has been active on the market for more than 20 years. The company has a large customer base and the necessary technical expertise to advance our goals in this important market. This includes raising our profile, educating people about our product range and ultimately gaining market share," says Stefanie Theuerkauf, Sales Manager for the D-A-CH region. Polynova employs five sales staff and three in logistics, all of whom have a technical background. The company's own warehouse in Rothenburg also ensures the availability of the plastics.

"GRAFE fits perfectly into our product portfolio," says Thomas Weigl, co-owner and responsible for business development at the Swiss distribution company, whose employees recently underwent intensive training in Blankenhain. "Our customers come from the sports goods, housing technology, automotive supplier and medical technology sectors - there are many synergies with GRAFE." Weigl himself has extensive experience in the masterbatch sector and has worked for two companies in the industry - Sukano and Americhem - as managing director. "Swiss companies want Swiss contact persons. We speak the languages German, Italian and French, are on site in the shortest possible time, offer direct contact and understand the needs of the customers and the requirements of the market," he explains. "Polynova is thus faster, closer and more direct." "The Swiss market is large and important for us," reports Theuerkauf and Weigl explains the background: "There are over 300 plastics processors, many are family-run and very technically oriented. The origins of the companies are often in the watch industry and in the production of the smallest precision parts such as gear wheels. In addition, coffee machine manufacturers, medical technology providers and automotive suppliers are important market players. A large number of well-known OEMs are located here."

Even though there are already masterbatch manufacturers in the Alpine country, says the sales expert, no one has the know-how to adjust compounds and masterbatches as perfectly and precisely as the company from Thuringia. In addition to a complete range of colours on practically all plastic substrates, flame retardants, UV additives, thermal stabilisers or lubricants are further examples of the extensive product portfolio. GRAFE is one of the specialists in the modification of thermoplastics and is an innovation driver in the production of colour masterbatches. "The technical possibilities in terms of a state-of-the-art technical centre and production machinery, as well as one of the largest research and development departments in the industry, are also not to be found elsewhere on the Swiss market. Our task now is to bring these to the attention of domestic customers," says Thomas Weigl, co-owner of Polynova AG together with founder Renato R. Huebscher.

“When it comes to working on new developments, we always start from new ideas and the constant research that starts from a concept that becomes reality, by increasingly raising the bar of sustainability” said Alice Tonello, R&D and Marketing Director of Tonello. “The research for technologies and solutions have always been part of our DNA, is a daily commitment to the environment, the market, our people and all human beings with their needs.  Based on this vision, two revolutionary patent-pending process, are born, Wake and OBleach, that allow to create incredible and totally responsible effects on garments” continued Alice Tonello.

This is how The Laundry (R)Evolution was born: a radically new conception thought to simplify and optimize the entire garment finishing process.

It involves only 2 technologies in the entire finishing cycle, reducing waste and optimizing resources: LaserBlaze, and The All-in-One-System. Metro is used, a software that processes real data, in real time to check all laundry consumption, optimizing processing times and improving performance.

The All-in-One System performs all washing operations by integrating 4 sustainable technologies into a single machine: ECOfree 2, which uses ozone in both the water and air; NoStone® for authentic and pumice-free stone-wash effects; UP, for washing processes with at least 50% less water; Core, a nebulizing system improving performance and reducing water consumption.

In terms of effects, the latest results of the Laundry (R)evolution are OBleach and Wake.

OBleach is the new Tonello patent-pending process which, by using only ozone, “returns to the future” with an authentic, sustainable and cool Bleach.

Wake is the first totally natural dyeing system. In fact, it uses only plants and vegetable waste, organic items like flowers, berries and roots left to dry and infuse, without harmful chemicals additives.

Tonello will be live during DenimsandJeans Virtual Show on October 14th and 15th.

• 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.

Twelve companies from eight different countries will receive a JEC Innovation Award at JEC Asia 2018. Asia-Pacific is an innovative region that sets the tone for all other regions of the globe. Once again, the JEC Innovation Awards highlight how composites bring solutions considering the new challenges in terms of efficiency, sustainability and life-cycle analysis.

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

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

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

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

• JEC World 2018, closes its doors on March 8 with a record increase in attendance resuming 3 days of vibrant networking and knowledge sharing.

The event confirms its leading position of JEC Group as number one organization for the promotion and development of the composites industry. Indeed the show welcomed more than 1,300 exhibitors from every continents and counted 42,445 professional visits from 115 countries. “The ability of JEC Group to gather the whole composites Industry under one roof over 3 days lies in the fact that we always initiate new precursory programs to the service of composites professionals.” says Ms. Frédérique Mutel, JEC Group President & CEO. “This year we initiated new programs, for instance the Composite Challenge allowing 10 PhD students to pitch their thesis in front of the industry, thus facilitating connections between students and industrialists. In the same spirit, we increased in power our Start Up Booster and Innovation Award Programs to accelerate relations between young or innovative companies with investors or established enterprises. We also introduced one new planet called “Make it Real” along with the Aero, Auto and Construction planets. In this planet, we could discover astonishing futuristic products for example the Aeromobil, a flying car that would revolutionize urban transportation in the near future,“ she adds. “We launched our new Book on Natural Fibers: Flax and Hemp. We had strong communications on Composites Environmental Input and Recycling.”

The event was the first event to promote and host the new “French Fab”, a French government initiative to internationally promote the French Industry and Manufacture. Also, JEC World welcomed the French Secretary of State to the Minister of Economy and Finance Ms. Delphine Gény-Stephann, visit that demonstrates the growing role of composites in the industry.

Inspiring Keynotes to foster composites disruption

Dirk Ahlborn,CEO of Hyperloop opened the Startup Booster ceremony by supporting the spirit of ingenuity in the Industry. Dayton Horvath, industry expert and consultant in additive manufacturing presented his vision of how to apply artificial intelligence to composite Materials and Manufacturing. Finally, Yves Rossy, the “jetman” using the latest carbon-fiber wings for flight introduced the JEC Innovation awards ceremony, motivating the audience to pursue their dreams and explaining how composites could made his dreams come true.

The "Public Choice” Awards Winners

A first at the show this year was the introduction of the public votes to elect their favorite projects among two JEC programs promoting innovation. “The goal to create the “public choice awards” was to involve and embark our community to make their innovation loud. Our vision at JEC is to demonstrate and to make understand towards a broader scope the vast range of possibilities that composite materials offer.”
