Trevira expands its Technical Textiles activities
The fibre and filament producer Trevira has been participating for the first time at Techtextil North America in Anaheim, California, as well the company will be present at Textile Solutions these days at Hannover Fair (D) and at Techtextil 2013 in Frankfurt next June
The Trevira programme entails fibres (including bio-component fibres) in polyester and PLA (IngeoTM), flame retardant and other special fibres and yarns in polyester, standard and spun-dyed filaments, as well as microfilament and hybrid yarns.
The filaments cover a broad range of applications for Technical Textiles. Flame retardant yarns for the construction of exhibition stands and print base materials (Trevira CS) are now standard. Additionally there are special yarns for medicine and hygiene textiles, as well as textured PBT filaments as a basis for trans-dermal patches and bandages.
Using thermal treatment, textile fabrics made from these hybrid yarns dan be controlled and shaped almost at will, and finally fixed in this state, they can be described as thermoplastic composites / prepregs. The single material composition of these products (100 % polyester) allows recycling. They can be finished in a variety of ways, all energy saving and they are as well dyeable and printable. All of this is offering an 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 are in line with important international fire standards.
Staple fibres are focused on customer specific product developments. Standard elements are short cut fibres for airlaid and wetlaid applications such as in hygiene products or for the paper industry’s use. Flame retardant fibres are also making a n inroad in nonwoven products.
Trevira’s extensive range in bico fibres are based on various raw material combinations, such as PET/PE, PET/Co-PET and PET/PBT. Bico fibres 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, but also for hygiene products. The sustainability concept is mainly based on optimising existing products in the PES fibre programme, such as a PET/PE fibre with low melting point, saving energy during processing and/or allows a higher operational throughput. The range of fibres in biopolymers (PLA) for a variety of technical applications has been extend and does include now a PLA/PLA bico fibre and is just arriving at the commercialisation stage. At Trevira headquarters in Bobingen (D) work is proceeding on the development of a concept for recycling Trevira products.
