Trevira to present fibres and filaments for technical applications at Techtextil

This year the leading fibre manufacturer Trevira is once again exhibiting at the Techtextil trade fair that takes place from 4-7 May in Frankfurt, seeking to strengthen its existing contacts with manufacturers of technical textiles and nonwovens and to gain new customers.

As at Index 2014, the company is making a joint presentation with its owner Indorama Ventures and sister companies FiberVisions and Wellman. Their stand offers a wide portfolio of man-made fibres.

Fibre sector

In the fibre sector the focus for Trevira lies in customised special solutions in polyester, PLA and bico fibres. Fibres from biopolymers (PLA / Ingeo) for a variety of nonwovens make up an essential element in the product programme. Trevira is the most important partner in staple fibres of NatureWorks, its supplier of raw materials.

Initially used principally in hygiene products, bico fibres are appearing more and more in developments for customer projects aimed at technical applications, like filtration or insulation, the company reports.

Flame retardant fibres are increasingly gaining ground in technical textiles as well. In this area Trevira intends to extend business particularly in nonwovens, and to concentrate on customised applications in soundproofing, insulation and applications in the automotive sector. Further attention is going to short cut fibres for a great variety of end uses, such as wallpaper and food packaging.

Filaments range

Trevira filaments cover a steadily growing spectrum of applications in technical textiles for standards, but also for niche products and for requirements that are constantly becoming more specialised.

Technical applications for Trevira filaments include special yarns for medicinal and hygiene textiles, together with textured PBT filaments as basis for plasters and bandages containing active ingredients. Meanwhile, demand has been rising steadily for PLA multifilaments.

Hybrid yarns

Hybrid yarns for stiffened materials constitute a rapidly growing specialty, where a yarn from a co-polyester filament, modified at melting point, is combined with another yarn. According to a demand, this latter can be either a Trevira standard or flame retardant filament. Combinations with high tenacity filaments, possibly glass and carbon filaments, are also conceivable.

Textiles made from these components can be shaped almost at will, but in a controlled manner and they can be fixed in this form. In the composites segment such intermediate products are designated thermoplastic prepregs – materials much in demand in modern automotive construction.

Technical applications for flame retardant hybrid yarns in rather textile materials are, for instance, acoustic materials, exhibition construction textiles, and advertising banners. In home textiles interior sun shading can be added to the list. The textiles can be coloured and printed, and there are in addition articles from spun-dyed yarns. Made from 100% polyester, the fabrics can also be recycled.
