Trevira has intensified its activities in the field of technical textiles. This year the fiber and filament producer will not only be appearing again in June at the Technical Fair in Frankfurt, but, for the first time, also in March at Techtextil North America in Anaheim (California/ USA), and at Textile Solutions, took place in April as part of
the Hannover fair. The Trevira program covers fibers (including bicomponent
fibers) in polyester and PLA (Ingeo™), flame retardant and other special fibers and yarns in polyester, standard and spun-dyed filaments, as well as microfilament and
hybrid yarns.
Trevira filaments cover a broad range of applications for technical text iles. Flame reta rdant yarns for th e construction of exhibition stands and print base materials
(Trevira CS) a re now standa rd. In addition, the re a re special yarns for medicine and hygiene textiles, as well as textured PBT filaments as a basis for transdermal patches and bandages. Hybrid yarns constitute an important specialty. Here a low-melt component (NSK) is combined with a Trevira standard or flame retardant filament.
Using thermal treatment, textile fabrics made from these hybrid yarns can be controlled and shaped almost at will, and finally fixed in this state. They can in fact also be described as thermoplastic composites / prepregs. The single-material composition of these products (1 0 0% Polyester) means they can be recycled. They can be finished in a variety of ways, all energy saving, and they are dyeable and printable. This makes them an interesting alternative, in both ecological and economic terms, since a stiffening coating of acrylate, for example, becomes superfluous. When used in combination with flame retardant Trevira filaments the materials satisfy important international fire standards.
Mixing Trevira NSK filaments with glass and/ or carbon filament makes it possible to produce high-performance thermoplastic composites or prepregs, e.g. for vehicle construction.
With staple fibers Trevira continues to focus on customerspecific product developments. Standard elements in the delivery program are short-cut fibers for airlaid and wetlaid applications, for instance in hygiene products or the paper industry. Flame reta rdant fibers are also in cre a sin gly to be fo un d in n o nwo ve n p ro ducts. The extensive range in bico fibers comprises the various raw material combinations, such as PET/ PE, PET/ Co- PET and PET/ PBT. Bico fibers in core-sheath technology are used primarily in the manufacture of thermally bonded materials (nonwovens), for instance in the automotive sector, for insulation and filtration materials, and also for hygiene products. In new developments within its fiber program Trevira is focusing more and more on ecological solutions.
The sustainability concept in this product range is mainly based on optimizing existing products in the PES fiber program, such as a PET/ PE fiber with low melting point. This saves energy during processing and/ or allows a higher operational throughput. In addition, the range of fibers in biopolymers (PLA) for a variety of technical applications has been extended. It now includes a PLA/ PLA bicofiber that is currently at the commercialization stage. Recycling is also an imp ortant issue. At Trevira headquarters in Bobingen work is proceeding on the development of a concept for recycling Trevira products.
