From the Sector

Vom 23. bis 26. April präsentiert die CHT auf der Techtextil 2024 nachhaltige Hilfsmittel für technische Textilien.

Das Produktportfolio der CHT Gruppe umfasst wässrige, aber auch silikonbasierte (z.B. LSR) Ausrüstungs- und Beschichtungssysteme, die neue innovative Funktionalitäten zulassen.

Produkte der TUBCOSIL-Reihe sind LSR-Beschichtungen, die auf fast allen Textilien und Nonwoven appliziert werden können. Aufgrund ihrer Materialeigenschaften können sie höchste technische Anforderungen hinsichtlich Beständigkeit, Mechanik, Haptik und Optik erfüllen. TUBCOSIL-Produkte sind lösemittelfrei und somit auch aus ökologischer Sicht interessant.

Ein sortenreines Endprodukt (z.B. Teppiche, Filter, Gepäcknetze usw.) lässt sich leicht recyceln und kann damit dem Wertstoffkreislauf wieder zugeführt werden. CHTs TUBICOAT PET-Linie ist speziell für sortenreine Materialien auf Basis Polyester (PES) entwickelt worden.

TUBINGAL® RISE ist der erste Textilweichmacher der CHT Gruppe aus recycelten Silikonen. Ganz im Sinne der Kreislaufwirtschaft werden „End-oflife“-Silikone wiederverwertet und mit Emulgatoren aus nachwachsenden Rohstoffen zu einem neuen hydrophilen Weichmacher formuliert. Die Produktqualität ist identisch zu einem Silikonweichmacher aus Primärrohstoffen – nur nachhaltiger. TUBINGAL® RISE ist für alle Faserarten geeignet.

Ebenfalls nach den Prinzipien der Kreislaufwirtschaft hat die CHT Gruppe das Produkt ARRISTAN rAIR entwickelt. Hierbei werden Kunststoffabfälle in ein hochwertiges Textilveredelungsprodukt umgewandelt, um damit beispielsweise ein optimales Feuchtigkeitsmanagement bei Sport- und Aktivbekleidung zu erzielen. Weitere Anwendungsfelder sind Socken und Strumpfhosen im Bekleidungsbereich, Filtrationsmedien und Vliesstoffe im Bereich der technischen Textilen sowie Kissen und Vorhänge bei den Heimtextilien.

POLYAVIN bPEN ist die neue Plug-in-Lösung zum Ersatz von fossilen Rohstoffen. POLYAVIN bPEN ist das erste Ausrüstungsmittel mit einer Kohlenstoffaufnahme. Die Reduktion wird durch die Verwendung von biobasierten Rohstoffen, die Kohlendioxid aus der Atmosphäre binden, erreicht. Das Produkt kann als Prozesshilfsmittel eingesetzt werden, um die Reibung von Garnen zu verringern, um Nähschäden bei der Konfektionierung zu verhindern, um gleichmäßige Raueffekte zu erzielen sowie um das Sanforisieren/Kompaktieren von Maschenwaren und Geweben zu unterstützen. POLYAVIN bPEN eignet sich auch als Leistungsadditiv zur Erhöhung der Reiß- und Scheuerfestigkeit sowie zur Veränderung der Haptik.

Produkte der APYROL-Reihe sind Flammschutzmittel, die im Brandfall die Flammenausbreitung zeitlich verzögern und so gefährdeten Personen mehr Zeit für Rettungs- bzw. Löschmaßnahmen oder zur Flucht verschaffen.

Eine Weiterentwicklung, speziell für die Anforderungen im Bereich wässriger Beschichtungen, stellt die neue PFC-freie Hydrophobierungsgamme unter der Bezeichnung ECOPERL COAT dar.

Die TUBICOAT PU ECO-Gamme umfasst biobasierte Beschichtungslösungen auf Basis von wässrigen Polyurethandispersionen.

Freudenberg Performance Materials (Freudenberg) is showcasing solutions for the automotive, building, apparel, filtration and packaging industries at this year’s Techtextil in Frankfurt am Main from April 23 – 26.

Sustainable nonwoven for car seats
One innovation highlight at Techtextil is a novel Polyester nonwoven material for car seat padding. Also available as a nonwoven composite with PU foam, it is not only easier for car seat manufacturers to handle during the mounting process, but also ensures better dimensional stability as well as providing soft and flexible padding. It has a minimum 25 percent recycled content, for example, by reusing nonwoven clippings and waste, and is fully recyclable. Full supply chain transparency enables customers to trace and verify the content of the nonwoven and thus ensures a responsible production process. The Freudenberg experts will also be presenting several other nonwoven solutions made of up to 80 percent recycled materials that can be used in car seat manufacturing.

Biocarrier for green roofs
Freudenberg is showcasing a sustainable carrier material for green roofs on urban buildings at the trade fair. The carrier is made from polylactide, i.e. from renewable resources. When filled with soil, it provides a strong foothold to root systems, enabling the growth of lightweight sedum blankets that can be rolled out to provide instant green roofs. These roofs not only help counter urban heat, they also improve stormwater management and regulate indoor temperatures.

From textile waste to padding
The company extended its circular thermal wadding product range with the release of comfortemp® HO 80xR circular, a wadding made from 70 percent recycled polyamide from discarded fishing nets, carpet flooring and industrial plastic. Because polyamide 6, also known as nylon, retains its performance characteristics after multiple recycling processes, the fibers can be used again and again to manufacture performance sporting apparel, leisurewear and luxury garments.

Packaging solutions with various sustainability benefits
Freudenberg is also showcasing products for sustainable packaging and filtration solutions. The long-lasting Evolon® technical packaging series is a substitute for disposable packaging used in the transport of sensitive industrial items such as automotive parts. The material is made from up to 85 percent recycled PET. A further highlight at Techtextil are Freudenberg’s fully bio-based solutions for manufacturing dessicant bags. The binder-free material based on bio-fibers is also industrially compostable.
In addition, the experts will be giving trade fair visitors an insight into Freudenberg’s filtration portfolio.

At the PERFORMANCE DAYS Functional Fabric Fair in Munich on 20 and 21 March 2024, CHT will present its latest sustainable textile technologies with a focus on dyeing and effect chemicals.

These products are used to finish textiles with special functions such as water repellency, breathability and efficient moisture transport. Significant amounts of water and energy can be saved during the dyeing and finishing process, resulting in a lower CO2 footprint.

In addition to effect chemicals, CHT will be presenting its dyeing products with a focus on the use of bio-based, biodegradable and recycled materials to support the circular economy.

Hexcel will continue to celebrate its 75th anniversary and highlight its latest developments for the Marine market at METSTRADE 2023 on November 15-17. Hexcel will showcase innovative advanced lightweight material technologies including new intermediate and high modulus fiber HexPly® M79 prepregs and present example high-performance superyacht and windship components developed by customers using Hexcel materials.

The new intermediate modulus prepreg combines the low temperature curing and simple processing of the DNV GL accredited HexPly M79 resin system with the market-leading stiffness of HexTow® IM2C fiber, creating a uniquely optimized composite material for highly loaded components. Originally developed to provide best-in-class performance for America’s Cup and IMOCA hull and deck structures, the new combination minimizes structural deformation under load in parts such as rigs, foils, and other appendages.

For a high modulus solution, HexTow® HM54 fiber is also now available with the HexPly M79 resin system. The unique mechanical properties of HexTow HM54 fiber allow structural designers to achieve higher safety margins for both stiffness and strength critical applications. Both products can be manufactured with Hexcel G-Vent technology for out-of-autoclave processing, delivering a reduction in process time and cost without compromising mechanical performance.

Hexcel will also display customer products that have benefited from the performance and processing gains provided by HexPly materials. A section of a Solid Sail mast made using Bureau Veritas (BV)-approved HexPly® M9.6 prepregs will be exhibited at METS. Such masts are used for wind propulsion and, by harnessing the power of ocean winds, they reduce reliance on engines, reducing fuel usage and emissions.

Visitors to the Hexcel booth will also see a section of a radar arch part from luxury motor yacht builder Sunseeker made using HexPly® XF surfacing technology and HexPly® SuperFIT semi-pregs. The part is lighter in weight and stiffer than versions made using resin-infusion processes and de-molds with a pinhole-free surface that needs minimal preparation to be ready for painting. Sunseeker has recorded an overall reduction in process time and material costs of around 30% against traditional prepreg parts, using Hexcel composite materials.

With a ribbon cutting ceremony on October 24, 2023 CHT USA celebrated the $ 25 million expansion at its US headquarters in Cassopolis, Michigan. More than 100 attendees came to the celebrations, among others officials from local, county and state governments, neighbors, and area business leaders, CHT employees, CTO Dr. Bernhard Hettich as representative of CHT’s Global management team, and members of the press.

In his speech, Dr. Bernhard Hettich, CTO of CHT Group, thanked the local authorities for their business-friendly policies and stated that a development towards sustainability in many areas would not be possible without CHT's silicone products: "With CHT's largest single investment outside Europe, CHT is taking a big step and doubling its silicone production capacity. We intend to use this expansion not only to support our customers in the Americas, but also to leverage the capacity for our global growth. In line with the motto "CHT first", further steps in this direction will follow."

For the Cass County site, the approximately 45,000 square feet new facility with 5 reactors and distillation units resulted in an increase in the total area of the company's site to 120,000 square feet. This will then allow sufficient space for additional reactors and downstream processes. The CHT USA site expansion has created approximately 30 highly skilled jobs in the community.

CHT USA’s Regional Sales and Marketing Director NORAM, Matthew Loman hosted the Ribbon Cutting ceremony.

Germany-based ZwissTex is a leading manufacturer of textiles with over 150 years of experience, creating innovative and sustainable textile solutions for the automotive and apparel industries. The company also operates in Mexico, to specifically serve the automotive sector across North American Free Trade Agreement (NAFTA) markets. Via OEMs, ZwissTex supplies German automakers including Volkswagen Auto Group, BMW, and Mercedes, as well as American manufacturers in select cases.

Unlike other Kornit customers, ZwissTex had no previous experience printing their own materials, and saw Kornit’s sustainable, single-step, Presto MAX S production system as an effective means of increasing their product capabilities.

“Our textiles were not classically printed in the past, and we did not produce any classical textiles in fashion, which is why we didn’t have any printing experience internally,” said Ralph Moldan, Technical Specialist at ZwissTex, as the system was being installed in their facility. “The only option was to find a system that would enable us to implement the areas in which we are active on the market easily and quickly, without requiring a lot of printing experience.”

One benefit of integrating Kornit technology into the ZwissTex production ecosystem: applying ink only where it is needed and seen, rather than to the full surface of each material. This translates to both reducing the company’s carbon footprint, and minimizing materials waste for a more cost-effective operation.

Prior to making the decision to invest in Kornit, ZwissTex conducted a series of tests and consultations, evaluating possible applications for different materials and engaging with their own key clients to ensure these finished products would meet their rigorous quality and durability standards. This included presenting Kornit-decorated samples at the Techtextil 2022 exhibition in Frankfurt.

Moldan found Kornit’s production capabilities opened new doors to customization of interior areas, a market that continues to grow. He anticipates this technology will create new opportunities with customers they could not reach previously, including new opportunities in sectors such as motor homes, airlines, and aircraft outfitters.

CHT and Fulgar have collaborated to support the goal of reducing the carbon footprint with an effective and sustainable solution for the textile market.

Combining FULGAR’s circular economy ready yarns with CHT’s resource-saving dyeing techniques significantly reduces the usage of natural resources and leads to lower environmental impact and ultimately a lower carbon footprint. The combined process needs less water, uses less energy, and saves time while meeting the color fastness standards for finished textile products.

The combination of 100 % biobased polyamide EVO® by FULGAR yarns with CHT sustainable dyeing application can save water up to 64 %, energy use up to 50 % and process time up to 50 %, when compared to standard dyeing processes. Sustainable dyeing of EVO® is promoted using CHT’s soy-based dyeing auxiliary SARABID TS 300. SARABID TS 300 has accredited a C2C Certified Material Health Certificate at Gold level and USDA Certified Biobased Product Certification.

EVO® by FULGAR, the totally renewable yarn based on castor plants, does not require high amounts of water - 4 times less compared to cotton. In addition to the sustainable aspect, EVO® by FULGAR offers characteristics like lower fiber weight, particular moisture management and higher stretch often without the need for elastomer fiber. This helps to avoid material mixes for better recycling opportunities. EVO® provides greater user comfort, mainly for performance and casual apparel.

• Reaktivfarbstoffe für wasser- und energiesparende Färbeprozesse mit stark verkürzten Prozesszeiten

BEZAKTIV ONE deckt ein breites Spektrum an außergewöhnlich starken Farbstoffen ab. Dies ermöglicht kosteneffiziente Färbeprozesse mit weniger Farbstoff und Salz. Das ausgezeichnete Auswaschverhalten ermöglicht kurze Spülprozesse bei tiefer Temperatur und bietet dadurch einen weiteren ökonomischen und ökologischen Vorteil. Die Farbstoffe eignen sich durch ihre gute Mehrfachwaschechtheit besonders für langlebige Textilien.

Zellulosefasern werden häufig mit Reaktivfarbstoffen gefärbt, da diese in einer Vielzahl von Farben kommerziell erhältlich sind und Färbungen mit hoher Waschechtheit ergeben. Reaktivfärbungen benötigen durch die notwendigen Spülprozesse jedoch viel Wasser. Aufgrund der gestiegenen ökologischen Anforderungen ist die Entwicklung energie- und wassersparender Verfahren eine Kernanforderung an neue Farbstoffe.

Eine minimale Anzahl von Spülbädern und generell niedrigere Temperaturen der Färbe-, Spül- und Seifbäder tragen zu effizienten wasser- und energiesparenden Färbeprozessen bei.

BEZAKTIV ONE Farbstoffe können zwischen 40 und 60 °C gefärbt, gespült und geseift werden. Daher ist der Ausziehfärbeprozess im Vergleich zu herkömmlichen Reaktivfärbeverfahren, bei denen Temperaturen zwischen 60 und 98 °C erforderlich sind, deutlich kürzer. Dieser Vorteil bedeutet für den Textilfärber Einsparungen bei der Prozesszeit und eine höhere Produktivität.

Besonders deutlich werden die Vorteile des Verfahrens bei mittleren bis dunklen Farbtönen. Durch die Kombination von hohem Fixiergrad und gutem Farbaufbau können insbesondere dunkle Nuancen mit geringeren Farbstoff-Einsatzmengen als mit herkömmlichen bifunktionellen Reaktivfarbstoffen erreicht werden. Durch die Zugabe des Hilfsmittels COTOBLANC SEL im zweiten Seifbad ergibt sich ein zusätzlicher positiver Effekt, so dass ein Waschprozess mit geringem Wasser- und Energieaufwand zu hervorragenden Nassechtheiten auf dem Textil führt.
