From the Sector

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.

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.

ANDRITZ will be presenting its innovative solutions for nonwovens production and textile manufacturing at INLEGMASH 2022 in Moscow, Russia, from March 14 to 17.

AIRLAY TECHNOLOGY
Protecting the environment and conserving natural resources require new technologies. In the textile-related industries, the current challenge is to develop industrially and economically viable solutions to use eco-friendly fibers in nonwovens. ANDRITZ focuses on the airlay nonwoven application for hemp fibers (used in mattress production, insulation, ...) and also geotextile end uses.

TEXTILE RECYCLING TECHNOLOGIES
ANDRITZ Laroche is a leading supplier of fiber processing technologies such as opening, blending, and dosing, airlay web forming, textile waste recycling, and decortication of bast fibers. 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. ANDRITZ will present recycling technologies for end-of-life textile products that can be used in multiple applications, such as automotive, insulation, mattresses, and furniture felts.

Customer awareness and regulations are pushing apparel brands to recycle their textile waste and use the recycled textile fibers in their own products. To support ANDRITZ customers, a team with process know-how is available to conduct customized trials in our advanced technical center located at the ANDRITZ Laroche facilities in Cours, France.

BAST FIBERS
For the demanding Russian market for technologies based on bast fibers, ANDRITZ will present innovative products and the valorization of bast fibers, in particular hemp.
ANDRITZ Laroche is a player in the textile waste recycling sector, with airlay nonwoven technologies but also bast fiber decortication and cottonizing lines.

These eco-friendly fibers are used to spin yarn mixed with cotton, saving cotton as raw material, which reduces the consumption of water, pesticides applied in its cultivation and chemicals used during the dyeing and finishing processes.
