From the Sector

Trevira CS is exhibiting for the first time at CSI Miami (Cruise Ship Interiors Design Expo Americas). Taking place on 6 – 7 June, 2023 at the Miami Beach Convention Center, CSI will bring together buyers and suppliers involved in cruise ship interiors, including interior designers, architects, outfitters, shipyards and suppliers.
 
On the Trevira CS stand, visitors can get an idea of the wide range of flame retardant fabrics suitable for use on board cruise ships. 53 fabrics from 20 Trevira CS customers will be on display that either have IMO certification and/or have been tested to the fire safety standards (FTP Code) required in the marine sector. Trevira CS fabrics are inherently flame retardant, meaning that their flame retardant properties cannot be washed out or lost through aging or use. This is due to the chemical structure of the polyester fiber: the flame retardant properties are firmly anchored in the fiber and cannot be altered by external influences. A surface-applied flame retardant finish is therefore not necessary.

In the marine sector, the demands placed on textiles are not only high in terms of fire protection, but also with regards to light resistance and durability. This is particularly true for textiles used in outdoor applications. These must be extremely robust, as they are exposed to moisture and sunlight. To meet these requirements, Trevira CS has launched a range of 30 new spun-dyed, UV-stable filament yarns. Besides color depth and durability, spun-dyed yarns offer another advantage: They are more sustainable because the fabrics made from them can be produced in a more environmentally friendly way than textiles that are dyed in one piece or consist of brightly colored yarns. In fabric production, a large share of resource consumption goes to the dyeing and finishing of fabrics as well as the use of chemicals and water. However, with spun-dyed yarns, these processing steps are unnecessary – the yarn immediately comes out of the spinneret in the desired color, reducing the products’ environmental impact.

The topic of sustainability is also taken up in other Trevira CS products. For example, Trevira CS fabrics are available in recycled versions. They consist of fiber and filament yarns obtained in different recycling processes. Filament yarns are produced using recycled PET bottles, they contain 50% post-consumer recycled material. Recycled fibers are obtained using an agglomeration plant and in further processing steps from residual pre-consumer waste from production. They consist of 100% recycled material (pre-consumer recycling). All flame retardant recycled Trevira® products are GRS (Global Recycled Standard) certified.
Fabrics made from these yarns are marked with the Trevira CS eco trademark. The prerequisite for this is a recycled content of at least 50%. Among the fabrics presented at the Trevira CS trade fair stand are 8 fabrics bearing the Trevira CS eco brand.

The long-term goal in developing sustainable products is undoubtedly to enter a circular economy. For this new path, an innovative Trevira CS product development was launched, producing flame retardant fibers and filament yarns from chemically recycled raw material. In this case, the basic raw material for the chemical recycling was PET bottles, but essentially it could be most any other PET recyclables, such as packaging material or even textiles. Chemical recycling involves depolymerization, a sequence of chemical reactions in which the polymer chains are broken down again into their original components, i. e. the monomers. In a further processing step, impurities are removed. Before the polymerization process is initiated, a small amount of MEG (mono ethylene glycol) is added.

The same technology used to produce the original (virgin) raw material for Trevira CS is also used here. The flame retardant modification is added during polymerization. In this way, the flame retardant properties are indelibly anchored in the polymer.

By recycling valuable materials such as packaging material, waste can be avoided. The raw material obtained from the recycling process is comparable to the original material can be used again in high-quality products.

The Trevira CS brand will be presented at Heimtextil 2022. This year the trade fair will be held as a one-time Summer Special from 21 to 24 June in Frankfurt am Main, Germany. The booth will feature more than 200 fascinating, versatile, flame retardant Trevira CS fabrics.

These will be displayed in the Long Stay Apartment installation. Changing lifestyles, living and working arrangements as well as the housing shortage in countless large cities mean the Long Stay Apartment segment of the hospitality sector has experienced exponential growth, becoming ever more important. For this reason, it is the focus of this year’s Trevira CS booth. The presentation of the “Long Stay Apartment by Trevira CS” is intended to familiarise visitors – particularly interior architects, designers and furnishers – with the trendsetting, innovative uses of Trevira CS fabrics in the contract sector.

For the design of the apartment installation, the traditional Trevira CS Fabric Competition 2022 was announced at the end of 2021 and invited all customers to submit their latest Trevira CS products according to certain specifications. The winning fabrics will be announced at the trade fair and specially exhibited at the Trevira CS booth.

Director Marketing & Business Development Anke Vollenbröker: “Our exhibition gives exciting new insights into the modern concept of the Long Stay Apartment, presenting the live application of our customers’ Trevira CS innovations. An apartment designed for Long Stayers is a special challenge since it has to provide more than a hotel room or even an ordinary rental apartment: It needs to be an attractive temporary home while also offering the services and advantages of a hotel. We have made the Long Stay Apartment particularly “textile” and included submissions from all participants of our Trevira CS Fabric Competition 2022.”

• 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.

Teijin Carbon Europe introduces a new thermoplastic carbon fiber tape (TPUD) based on PPS. The new Tenax™ TPUD with PPS matrix allows entry in new cost-sensitive markets while offering the typical TPUD advantages like high resistance to chemicals and solvents, low flammability, storage or shipping at room temperature and recyclability.  

Due to its flame retardant properties and low smoke emission, it can be used in interior applications of aircraft or rail vehicles, among others. The maximum continuous operating temperature is up to 220 °C. Very low water absorption, excellent creep resistance even at elevated temperatures and high dimensional stability round off the property portfolio of this new TPUD. It is therefore also suitable for demanding applications in the aerospace, oil & gas, sporting goods or industrial sectors, while remaining cost-effective. These properties make the product perfect for highly automated processing routes such as ATL or AFP in combination with overmolding for complex geometries. Production start for the Tenax™ TPUD with PPS matrix is the first quarter in 2021.

For almost 10 years, unidirectional tapes (TPUD) have been manufactured from carbon fibers and thermoplastics in Heinsberg, Germany. The semi-finished products have so far been offered with PEEK or PAEK – and PPS is now added to the list of available matrixes. PPS allows a lower process temperature compared to PEEK or PAEK. For the industrial market in particular, increasing the production rate to make processes more cost-efficient is an opportunity.
