From the Sector

Hexcel has collaborated with HP Composites S.p.A (HP Composites), a world leader in the production of carbon fiber components for automotive and motorsports, to develop carbon fiber Class A body panels. Hexcel HexPly® XF surfacing technology is being extensively used by the Italian component producer to manufacture external body panels and other components for supercars such as Alfa Romeo’s stunning new supersport sedans, the Giulia GTA, and GTAm.

With five production plants in Italy, HP Composites has built an impressive track record of high-performance composite successes on both road and racetrack. HP has combined this processing expertise with Hexcel HexPly® XF3 surfacing material, HexPly® M47, and HexPly® M49 prepregs, working to the highest standards set by the most prestigious supercar OEMs and leading motorsport teams.

Hexcel’s automotive composites portfolio is the result of decades of industry experience and the creation of strategic partnerships to develop and optimize leading-edge technologies. HexPly XF3 is an epoxy prepreg surface material, developed with processing input from the HP Composites team to address the challenges of producing high-quality Class A automotive body panel surfaces with excellent resistance to aging tests.

Applied as the first ply in the mold and after curing at 120-180˚C in an autoclave, HexPly XF3 produces a smooth part surface with no porosity, that requires minimal preparation for painting.

HexPly XF3 is supplied in an easy-to-handle roll format with good tack and drapability. After curing, it can be easily prepared for painting with a rapid sanding process. HP Composites has incorporated automated robotic sanding techniques for this finishing stage with the paint-ready HexPly XF3 surface providing excellent paint adhesion according to EN ISO 2409.

HP Composites typically uses autoclave processing for HexPly XF3 parts, maximizing weight savings and structural performance of the final components. In addition, HP has also developed its own proprietary press and compression molding processes, including Air Press Moulding® technology, compatible with HexPly XF3 and other HexPly prepregs for higher volume production series that require increased production rates.

“Our long-term experience has given us a detailed understanding of the critical features that influence how prepregs and surfacing technologies interact with different production processes,” said Abramo Levato, General Manager, HP Composites S.p.A. “The relationship we have with Hexcel is both highly technical and highly supportive. As a result we have a complete material package for high-quality Class A body panels that are formulated specifically with our requirements in mind.”

“Combining the expertise of HP with a strong technical interaction and collaborative dialogue, Hexcel and HP were together able to develop the optimum HexPly XF surfacing technology,” said Claude Despierres, VP Sales and Marketing, Hexcel. “With HexPly XF3 we satisfy the toughest industry standards.”

• FILO, 29th-30th September 2021, booth C5

Bemberg™ by Asahi Kasei has been invited to showcase at Filo fair, the international exhibition of orthogonal weaving yarns for clothing and furnishings, circular knitwear and technical textiles, in a new special area, a dedicated open space reserved to sustainable fibers that will allow visitors to discover all their production cycle and performances, in full relax and transparency.

Bemberg™, an exceptional fiber made from the smart-tech transformation of cotton linters pre-consumer materials and converted through a traceable and transparent closed loop process, will brings to Filo its history, experience, know-how and market partnerships to prove its versatility and design-driven look and touch Last but not least we are talking about a true circular economy-oriented ingredient, with certified sustainable performance: Bemberg™ is biodegradable and compostable material as verified by the INNOVHUB 3rd party test and it has GRS (Global Reycled Standard) certification from Textile Exchange proving recycling authenticity.

Bemberg™ application history starts with high-quality suit lining, but today we can find it in many other applications such as fashion couture, outerwear, innerwear, bedding, and sportswear where its amazing unique touch and quality is offering a distinctive performance.

And to prove all of this, Bemberg™ will be at Filo showing some selected fabric innovation, and three responsible-driven designers representing different and complementary part of contemporary consumer wardrobe: ZEROBARRACENTO, Maurizio Miri and WAXEWUL - who have all chosen Bemberg™ fiber to create special collections. Three different ways to see and represent how sustainability and style – even if completely different ones – together can be highly successful, performing and interesting to the new consumer.

ZEROBARRACENTO, a gender-neutral emerging outerwear brand focusing on zero-waste product development, selects Bemberg™ for two fundamental reasons: firstly, from a stylistic point of view for its extreme versatility: in the various collections we have adopted it to create Kimonos, padded jackets, wrap dresses as well as for the interiors of our garments, which are intended to be soft embraces for total physical and mental comfort. The second but no less important reason is that this fibre has circular values in line with their zero-waste commitment.

The concept of the brand "Maurizio Miri" has a strong personality and a clear intent: to create a product that stimulates the wearer towards beauty. A garment should not simply be worn, but it has also to create a perfect symbiosis with the person wearing it and generate an exchange of positive energies. The purpose is to make the individual feel in perfect harmony with their own image. With this aim in mind, the designer selects extremely precious Bemberg™ linings for their sophisticated tailor jackets. 

Finally, WAXEWUL, a brand of sartorial clothing and artisan accessories with an urban-afro soul that has environmental and social sustainability as its basic ethics. WAXEWUL will bring to Filo its brand-new product, the J_Hood Bag: a doubleface jacket with a comfortably removable hood that can be transformed into a finely hidden doubleface bag. An exclusive, innovative and sustainable garment with minimal impact on the environment made of BemBAZIN™ - a new generation of bazin created, patented and produced by Brunello which is composed by the high-tech and responsible fibers of Bemberg™ - on one side and of wax on the other, traceable and certified, guaranteeing a reduction in waste (two jackets in one) and a long-life cycle.

Composites Evolution Ltd has teamed up with leading natural fibre reinforcement specialists Bcomp to launch a new range of flax-epoxy prepreg materials, designed to offer enhanced sustainability without compromising on performance.

Evopreg ampliTex™ prepregs combine Composites Evolution’s high-performance Evopreg epoxy resin systems with Bcomp’s award-winning ampliTex™ flax reinforcements, to deliver a family of materials which offer outstanding performance for component applications.

To reach the full performance of natural fibres, Evopreg ampliTex™ prepregs have been tailored to be compatible with Bcomp’s powerRibs™ reinforcement grid, enabling the same stiffness and weight as thin-walled monolithic carbon fibre parts while decreasing the CO₂ footprint by 85% and improving safety thanks to a blunt braking behaviour without dangerous debris or sharp edges.

Composites Evolution’s Sales & Marketing Director, Ben Hargreaves, explains further.
“Sustainability is an increasingly important factor for many of our customers - particularly those involved in motorsports and high-performance automotive applications. As you’d expect in these sectors though, sustainability can’t come at the expense of performance the two must go hand-in-hand. This is something that other prepreggers can struggle with, as natural fibres behave very differently to carbon or glass, for example.”

Customers would be able to understand the strengths and weaknesses of natural fibre composites, and to show where and how they can be adopted without the need for significant changes to existing composite component production processes.

One such customer is Retrac Group, whose composites division is one of the UK’s most experienced composites engineering companies across motorsports, automotive and aerospace. It recently used Evopreg ampliTex™ + powerRibs™ to produce a demonstrator bonnet panel for a race-bred supercar. Project Manager Alan Purves explains.

“We’re seeing a growing interest in flax fibre composites, particularly in the motorsports and niche vehicle sectors. It is therefore essential that we have developed an in-depth understanding of the processing requirements and performance capabilities of these materials, and are ready to respond to our customers' requirements. Being able to tap into the combined expertise and experience of both Composites Evolution and Bcomp is proving invaluable.”

Devan Chemicals has been supporting high performance sport in the UK and Belgium with its ‘cool comfort technology’ Moov&Cool.

Worldwide, hot temperatures are a new reality that brings extra challenges for athletes. Thermoregulation technology is becoming more and more important in order for athletes to perform at their best on the pinnacle of sports.

Working alongside the English Institute for Sport (EIS) and Sally Cowan Ltd, the technology is being applied to garments with the aim of improving the thermal comfort of elite athletes.

Moov&Cool consists of a multi-functional polymer technology that proposes to absorb heat during performance and improve the moisture management properties of the fabric. The treatment has been designed to simultaneously react to sweat build up and heat emission.

In Belgium, Devan has been involved in the Gold2Gold project carried out by Sport Vlaanderen. Gold2Gold is a unique collaboration between sports, government and the industry to prepare Belgian athletes to perform better in hot environments during world-level championships. Thermoregulating technology is increasingly becoming a key aspect of endurance performance for elite athletes. At that top level, small differences in body core temperature can make the difference between being on the podium or sometimes not even finishing the race.

Schoeller Textil AG, the Swiss textile and technology company, announces a shift in leadership as Joachim Kath takes over as CEO. Following a 10-year career at the global textile solutions brand, CEO Siegfried Winkelbeiner is moving into his retirement later this month. Joachim Kath, who comes from the chemical industry, has been working closely with Winkelbeiner as COO at Schoeller for the past year and a half.

The transition comes after long-term planning. Since February 2020, and in close partnership with Siegfried Winkelbeiner, Joachim Kath (on the left) has been preparing as Schoeller COO to take over its management. Joachim Kath originally comes from Flensburg (DE) and, following his studies of Chemical Engineering in Karlsruhe, shaped his professional career in the chemical industry with Ciba (-Geigy) / BASF in Basel (CH). His career over 30 years has incorporated engineering, production and marketing & sales in diverse management functions – in a wide range of business segments for various industries and areas of application around the globe. Joachim Kath spent 12 years of his career dedicated to textile finishing, with a period of intensive travel in Asia and a 3-year stay in the USA.

Asked how he sees himself, Joachim Kath said: “The common thread running through all my assignments and business activities is process orientation, interest in new paths, and an instinct for what is feasible – with the goal of achieving customer benefits and satisfaction. Kath aims to ensure that Schoeller can continue to face the challenges of changing market requirements with outstanding and exceptional products, while evolving and innovating to stay ahead of consumer needs for the future. High performance capability, sustainable product development, premium quality, reliability, productivity, and keeping the customer as the central focus of all activities continue as essential keys to Schoeller’s continued business success.

Iluna Group comes back to Milano Unica with a great and important goal: to relaunch the qualities and dimensions of sustainability by going beyond the ingredient.

Iluna’s new path, which was born in a moment when the market seems to speak about “fragility”, begins with the investment in the renewal of machines, which allow it to fly ever higher in terms of high-tech developments, quality, definition, effects of yarns and patterns. The journey into the new dimension of responsible quality continues with ad hoc developments in the field of GRS (Global Recycled Standard) certified recycled yarns, aimed at unprecedented effects both in look, in performance and in the hands of fabrics. Including cord yarn, shiny threads and an expansion of the range of GRS yarns, previously available only opaque. The cord yarn is a precious yarn with a ROICA™ EF premium stretch yarn core, GRS certified and developed with 50% of pre-consumer waste materials content - double, covered with an equally recycled shiny thread; the bright and translucent is instead to add brilliant effects so far not possible with a GRS yarn.

The printing processes are also born from this constant search for innovation towards new materials and new techniques, becoming more and more sustainable: Global Recycle Standard (GRS)-certified sublimation printing and register printing carrying Global Organic Textile Standard (GOTS) certification. This one overlap exactly on the design and color the details, reaching where the dye cannot reach.

Diversification has become essential in today’s competitive market and the fragility of the moments experienced in 2020 was the stimulus to return to being here again, to return to action. Flexibility is the watchword today, along with research. And Iluna has managed to go further: starting from the ingredients at the base of the materials, last year launched a collection with natural dyes made with GOTS certified plant-based dyes, up to proposing magnificent prints with extraordinary effects for this edition of the Milanese fair.

The three dimensions of sustainability, design and innovation are thus finally linked thanks to valuable partnerships with expert and excellent reference companies that have allowed these new developments and these unique results thanks to advanced technologies designed specifically for Iluna, which is today the only company to offer ingredients, natural colors and prints, all three strictly certified.

Winding technology offers simplicity, productivity and product control for premium tissue products

Paper Converting Machine Company (PCMC)—a division of Barry-Wehmiller and a global supplier of high-performance converting machinery for the tissue, nonwovens, package-printing and bag-converting industries— is pleased to announce the launch of its Paragon tissue rewinder.

Paragon features a patent-pending center-surface design that produces superior caliper, bulk and diameter flexibility. Log winding takes place in a new-concept nest, comprised of a winding drum, winding belt, compound-motion rider roll and center drives.

"Paragon offers a completely new method of tissue rewinding,” said Andrew Green, PCMC Vice President of Tissue and Folding. “It is radical only in the sense that we made the wind nest as simple as possible. Usually when you increase a machine’s speed, you sacrifice ease of use, but we know customers want both. With Paragon, we created a machine capable of higher speeds that is easier to operate. It’s remarkable.”

Many of Paragon’s subsystems are proven technology solutions in use on PCMC’s trusted Forte rewinder, with several upgrades. Paragon’s enhanced web handling and grade changes are mainly recipe-driven, and its specially designed tools guide fast calibrations. Like the Forte rewinder, Paragon has an intentional open-access design, plus, typical areas to clean require less frequent attention, and recovery and restart occur safely and quickly. Paragon also closes the gap between humans and machines with a new Smart Touch human-machine interface (HMI), which delivers Industry 4.0 tools that transform data to action. Following high-performance design principles, the clean and modern interface provides enhanced operator help, and new smart analytic features offer insights to improve overall equipment effectiveness. The Smart Touch HMI works much like today’s mobile devices with swipe functionality, enabling a short learning curve and improved productivity.

“While the focus is on the new wind nest, a Paragon line is more than that,” said Green. “We added elements like advanced web handling and a state-of-the-art HMI. At PCMC, we are not into hyperbole, but we believe that this machine has raised the bar and is what future tissue-converting machines will be judged against. And, that’s why we called it Paragon.” 

Teijin Limited announced today that its Tenax™ carbon fiber prepreg has been adopted for a part of nacelle, or streamlined housing, for next-generation aircraft engine to be used by Airbus. A prototype of the nacelle part, which Nikkiso Co., Ltd. is developing for Airbus’s Propulsion of Tomorrow project, will be delivered to Airbus by the end of 2021.

The Tenax™ prepreg used for the nacelle part was developed especially for aircraft applications using high-performance and rapid-curing epoxy resin. Notably, the Tenax™ prepreg can be molded at a lower temperature and in a shorter time than conventional prepregs for aircraft applications. In addition to general autoclave molding, the Tenax™ prepreg also is suited to press molding for mass production, achieving excellent quality required for aircraft applications. Furthermore, it is compatible with automated fiber placement (AFP) therefore can be combined with automatic laminating technology and short-time molding to maximize production efficiency. The excellent productivity and cost efficiency of the Tenax™ prepreg were key reasons why it was adopted for Nikkiso’s nacelle.

Teijin is intensively accelerating its development of mid- to downstream applications for aircraft, one of the strategic focuses of its medium-term management plan for 2020-2022. Going forward, Teijin intends to further strengthen its carbon fiber and intermediate material businesses to contribute to increasing global sustainability, aiming to become a company that supports the society of the future.

Under vacuum, the new BB Engineering large-area filter produces a homogeneous, pure melt with a targeted IV setting for instance, for returning polyester production waste to the melt flow, but also for achieving a homogeneous viscosity in the case of virgin material.

BB Engineering has expanded its melt filter portfolio to include a patented large-area vacuum filter designed especially for processing polyester waste. The so-called Visco+ filter is already known as the key component of the BB Engineering VacuFil recycling system. Now, it is also available as a separate and easily-integratable upgrade component for existing systems. Within this context, the uses of the Visco+ are by no means limited to just decontamination. Here, the Visco+ offers the following solutions:

• IV homogenization: if an existing production system is struggling with IV fluctuations, the Visco+ is able to actively intervene and balance out any irregularities;
• IV increase: if the final viscosity is insufficient when processing recycled materials, the Visco+ can increase the IV without the negative impact of long residence times.

In this way, the Visco+ enables fast and flexibly-controllable viscosity build-up and reliable viscosity monitoring of the polyester melt using a to-date unique, patented process. Depending on the intended end use, the melt can be ad-justed to the further processing procedure in a targeted manner. The requi-site melt properties above all the intrinsic viscosity, but also the purity and homogeneity are achieved in a reliable and reproducible manner and can also be adjusted during ongoing operation.

As a melt filter, the Visco+ operates like a liquid-state polycondensation unit. A maintenance-intensive reactor or a deposit-prone stirring unit are not required. Moisture is removed from the PET in the filter, which – in conjunction with an adjustable residence time – results in the desired IV increase in the vacuum. This enables a controlled IV build-up of up to 30%. The intrinsic vis-cosity is the central quality figure in PET recycling and rPET processing. It determines the melt performance in the downstream production process and the properties of the end products. The intrinsic viscosity is continually moni-tored by means of an integrated viscosity measurement unit and reliably adjusted in the event of deviations (caused by disparate input qualities, for ex-ample). At the same time, the filter provides an enormous material surface compared to the volume and continuously renews this. To this end, contamination can be removed particularly effectively from the starting material by means of automatically-regulated high-performance vacuum (1-30 mbar).

The Visco+ is particularly suitable for recycling PET waste that is to be reused for high-end products.
