Trevira GmbH, specialist for functional fibers and yarns, is presenting products for a wide range of technologies and applications in the technical and functional textiles segment at Techtextil this week. It will exhibit jointly with sister companies in the Indorama Ventures parent group.
Amongst the latest developments in filaments are yarns made from biopolymers (PLA). Numerous applications focus on home textiles, project textiles (e.g. trade fair construction) and technical uses, but also functional apparel.
Another product novelty is a phosphorescent yarn, which continues to glow in the dark up to 7 hours after brief exposure to light. This development is of special interest for use in vehicle interiors.
A further new development is a high-tenacity, permanently flame retardant textured yarn that is being produced in collaboration with the sister company PHP. This is primarily suitable for furnishing textiles, where it is important, along with contract market performance, to combine greater tenacity with less elongation, as is the case for instance with wall coverings.
Demand for hybrid yarns for stiffened textiles is still growing. Recent developments for specific uses in this yarn programme aim at segments like knitted spacer fabrics, acoustic textiles and interior sun screening. In particular, spun-dyed and flame retardant variants take their place here.A new offering in biopolymer fibres is a PLA hollow fibre for the use in fillings. In response to customer demand in terms of product functions and material properties, the comprehensive product range for airlaid applications is being continuously enhanced. This also applies to special fibres for the carding sector and shortcut types for the paper industry; where the focus is on improving dispersion.
With regard to the increased need for fibres with additional functionalities and to the use of new combinations of raw materials, capacities in bico-fibres are being expanded. For both the polyester and the PLA programme, Trevira has also developed modified fibres for the hygiene sector (e.g. for wet wipes). These stand out due to their particularly soft handle.
