Teijin Frontier, the Teijin group’s fibres and products converting company, has launched its new Solotex Eco-Hybrid high-stretch side-by-side (S/S) conjugated fibre. It is an eco-friendly plant-derived polymer with a chemically recycled polyester polymer, each featuring different heat-shrinkage characteristics to enable the formation of coiled crimp yarn.
Solotex Eco-Hybrid represents a new line in Teijin Frontier’s polytrimethylene terephthalate (PTT) fibre Solotex family. Solotex Eco-Hybrid filament yarn and textile will be introduced as a featured product for 2020 autumn/winter fashion apparel, offering many possibilities for enhanced sportwear, uniforms, and more. Annual sales of Solotex Eco-Hybrid are expected to grow from JPY 500 million in 2020 to JPY 1.5 billion in 2022 (filament yarn equivalent).
The key features of Solotex Eco-Hybrid includes extra stretchability achieved with new technology for conjugating PTT polymer and polyethylene terephthalate (PET) polymer made with chemically recycled raw material, which are then processed to create a crimp structure. The crimp structure is equivalent to that of petroleum-derived raw materials. Dyeability is also achieved with optimised yarn-making conditions, according to a press release by Teijin.
Solotex Eco-Hybrid is eco-friendly and comes with a versatile fineness. It is very stretchable and dyeable, equivalent to those of petroleum-derived materials, and soft texture.
Solotex Eco-Hybrid has the same features as conventional S/S conjugated fibre made with petroleum-derived raw materials. Teijin Frontier’s existing S/S conjugated fibre comprises a highly stretchable Solotex PTT-fibre polymer made with about 40 per cent plant-based raw materials and PET made of recycled raw materials. The newest version, Solotex Eco-Hybrid, solves the problem of achieving a consistent crimp structure in an eco-friendly S/S conjugated fibre made with recycled PET.
