From the Sector

Lenzing presented at FILO its sustainable approach and on a selection of key innovations such as TENCEL™-branded specialty fibers.

As part of the space dedicated to Cittadellarte – Fondazione Pistoletto and Fashion B.E.S.T., the first Italian collective of responsible fashion designers, a selection of TENCEL™’s key technologies were under the spotlight:

• TENCEL™ x REFIBRA™, using cotton textile waste and wood pulp as the feedstock for cellulosic fibers, creating a circular solution;
• TENCEL™ x Indigo Color, infusing pigment into fibers directly during the spinning process;
• TENCEL™ Luxe, providing superior aesthetics, performance and comfort to be the perfect partner of other noble fibers such as silk, cashmere or wool;
• TENCEL™ Carbon Zero, offering carbon-zero CarbonNeutral®-certified products by Natural Capital Partners;
• TENCEL™ x Eco Clean, bringing totally chlorine-free-bleached TENCEL™ Modal fibers to the textile industry.

Lenzing's priority has been to produce fibers for many sectors (fashion, beauty care, cleaning, hygiene and home textiles) in a sustainable way. Each Lenzing product is made of cellulose from wood, a renewable natural resource, coming only from certified sustainable sources.
The Lenzing Group operates two commercial-scale biorefineries with 100% wood utilization, which ensure that the totality of wood constituents are used to produce fibers, biobased chemicals, and bioenergy, thus maximizing value creation from an economic and environmental perspective. This concept was illustrated by Carlo Covini, Lenzing Business Development Manager Italy & Switzerland, in his presentation “Lenzing’s biorefinery concept”.

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.”

Global energy consumption reached a record high in 2019, following a 40-year trend for rapidly increasing energy demand that was only halted by the Coronavirus pandemic. It’s estimated that more than 80 % of this energy is still generated from fossil fuels that produce CO2 emissions and contribute to climate change. Renewable energy offers a solution to this problem, but saving energy whenever possible is an even more effective approach. That are the motives for Trützschler to develop the intelligent card TC 19i, which sets a new benchmark for energy-efficient carding.

The intelligent Trützschler card TC 19i features the unique T-GO gap optimizer, which continuously and automatically monitors and adjusts the carding gap to an ideal position during production. Innovative drive- and air technology further reduce energy consumption of the TC 19i.

The most energy-intensive elements in a carding machine are the drive, the dust suction process and the compressed air system. Permanent suction is needed to remove dust and cotton waste in key places. Smart optimization of these areas has made the intelligent card TC 19i a benchmark for energy efficiency in carding because it uses less electricity, lower suction pressure and less compressed air than other machines, while providing the highest production rates currently available on the market.

In a head-to-head comparison between the TC 19i and a high-performance card from a competitor, the TC 19i consumed at least 10 % less energy per kilogram of material produced when manufacturing rotor yarn from a cotton and cotton waste mix. The compared energy values included electric power consumption and energy required for suction and compressed air and were measured in both cards at the same production of 180 kg/h. A 10 % reduction in energy per kilogram of sliver produced, as proven here by TC 19i, can have a significant impact on a spinning mill’s profitability; annual savings worth a five-digit sum are frequently possible, depending on factors such as the output of the mill. The customer trial also showed TC 19i’s excellent reliability at the customer’s usual production rate of 180 kg/h, and even demonstrated stable performance at 300 kg/h in the same application. Because the TC 19i with T-GO gap optimizer realizes maximum production rates at no compromise in quality, manufacturers can reduce their energy demand and investment costs drastically: Less machines are needed to achieve the desired output, and energy consumption per production is reduced.

This improvement was made possible by a long and sometimes challenging innovation process involving mathematical models of air flows, as well as flow simulations and prototypes. By combining the final flowoptimized parts in the TC 19i, Trützschler’s experts have developed a card that operates with suction pressure of just -740 Pa and with an air requirement of only 4200 m³/h. This translates into 40 % less energy demand for air technology compared to the latest high-performance competitor model.

More and more brands are actively speaking up against the use of PFAS chemicals in products and supply chains. ChemSec’s corporate initiative the PFAS Movement was started in 2020, with the aim of creating a network of companies that would like to see PFAS chemicals regulated more efficiently. As of September 2021, 50 companies have joined the movement.

PFAS, short for per- and polyfluoroalkyl substances, is a chemical family consisting of almost 5,000 industrially produced chemicals. In manufacturing, PFAS are favored for their durability and well-functioning properties. They provide features such as non-stick, water repellency and anti-grease to many types of everyday products, including cosmetics, food packaging, frying pans and clothes, just to name a few.

Lately, more and more reports have been suggesting that PFAS are a serious problem. Human epidemiological studies have found associations between PFAS exposure and a number of health disorders.

One of the biggest challenges connected to PFAS is that, with very few exceptions, they are perfectly legal to use. This means that the brands and retailers who want to stop them from being used as ingredients in their products have very limited ways of communicating this in the global supply chain. As long as there is not a restriction in place, suppliers will continue to use these very effective chemicals in manufacturing. That’s why companies act together with a unified voice, like in the case of ChemSec’s PFAS Movement.

WEIDMANN GmbH in Süßen is known worldwide as a specialist for the finishing of fiber and down-proof articles and woven industrial fabrics. Customers particularly appreciate the company's reliability and flexibility with regard to their individu-al requirements, and consistently high quality of its products. The Swabian textile manufacturer finishes premium fabrics, mainly for the bedding industry, using the latest technology and in an environmentally conscious manner.

The complex production and finishing processes for high-quality fabrics require a reliable and efficient machine technology. With this in mind, WEIDMANN has always relied on the proven stenter technolo-gy from BRÜCKNER. For many decades, the German textile machinery manufacturer has been a world leader in the con-struction of production lines for the finishing of classical textiles, woven industrial  fabrics, nonwovens, glass fabrics and floor coverings. In addition to stenters, the company's production program also in-cludes coating lines, relaxation dryers, sanfor lines, continuous dyeing lines as well as ovens for the bonding of nonwovens and other special lines. All machines are produced 100% in-house in Germany.

Both companies continuously invest in new and innovative technology in order to be successful and competitive today and in the future. Only Recently, a completely newly developed BRÜCKNER stenter was installed in the ultra-modern plant at WEIDMANN. During the intensive project engineering phase it soon became clear which features are of special importance for their daily production requirements:

• uniform moisture distribution in the machine entry and during pick-up of the specialized   chemicals in the finishing padder before the thermoprocess
• weft-straight fabric flow with minimized residual distortion
• very good accessibility for maintenance and daily cleaning
• sensor technology and automation of setting parameters for energy optimization
• heat-recovery with hot water generation for the dye house
• the line must be fully Industry 4.0 capable

Textechno reports launch of a new standard for the drapability and deformability of fabrics and non-wovens: ISO 21765

World market leader for precision testing equipment Textechno and their partner SAERTEX, global market leader in non-crimp fabrics (NCF) are proud to announce that the newly developed international standard ISO 21765:2020 to quantify material behaviour in terms of drapability and deformability was recently published by ISO.

The new standard ISO 21765 allows the world-wide comparable measurement of all relevant parameters regarding the deformability and drapability of all kinds of fabrics, including woven fabrics and NCFs as well as knitted fabrics and non-wovens on Textechno´s precision testing equipment DRAPETEST. This can be very useful in the carbon fibre recycling since one of the most efficient applications of recycled carbon fibres will be in non-wovens.

This is the first testing instrument world-wide to quantify not only the force which is required for deforming a fabric, but also the various defects such as gaps, undulation, or wrinkles which can arise due to the deformation.

In the frame of a publicly funded project which started in 2011, Textechno developed the award-winning automatic drapability tester DRAPETEST along with other partners, amongst them SAERTEX.  

Dietmar Möcke, CTO at SAERTEX says: „With ISO 21765, we finally have a standardized testing method with world-wide validity. It allows us to provide our customers with comparable and reproducible measurement values regarding the draping characteristics of our products.”

Ulrich Mörschel, Managing Director of Textechno adds: “We are grateful for the support from all around the world allowing us to establish the new ISO standard. The standard finally fills a gap in the testing methods for fabrics both in the fields of textiles and composites.”

Dr. Michael Effing, Managing Director of AMAC GmbH and Senior Advisor to Textechno: “A lot of research is dedicated to new production technologies of composites, non-crimp fabrics and classical fabrics for thermosets have with 33 % a significant market share in the production of all composite materials. The application of the new standard for non-wovens from recycled carbon fibres comes perfectly on time for this market sector which will gain more and more importance within the next years.
