Teijin Frontier’s new high-stretch SOLOTEX®ECO-hybrid fiber made with plant-derivedand recycled materials

Teijin Frontier Co., Ltd., the Teijin Group's fibers and products converting company, announced today its new SOLOTEX®ECO-Hybrid high-stretchside-by-side (S/S) conjugated fiber an eco-friendly plant-derived polymer with a chemically recycled polyester polymer, each featuring different heat-shrinkage characteristics to enable the formation of coiled crimpyarn.

SOLOTEX®ECO-Hybrid represents a  new  line in Teijin  Frontier’s polytrimethylene terephthalate (PTT) fiber 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-Hybridare expected to grow from JPY 500 million in 2020 to JPY 1.5 billion in 2022 (filament yarn equivalent).

Key Features of SOLOTEX®ECO-Hybrid

Polymers

Extra stretchability achieved with newtechnology for conjugating PTTpolymer and polyethylene  terephthalate  (PET) polymer made  with chemically recycled raw material, which are then processed to create a crimp structure.

Filament production

Crimp   structure is equivalent   to that   of petroleum-derived   raw materials.Dyeability achieved with optimizedyarn-making conditions.

SOLOTEX®ECO-Hybrid has  the  same  features  asconventional S/S  conjugated  fibermade with petroleum-derived raw materials.

Eco-friendly

PTT  polymer is  partly  made  with plant-derived  raw  materials  and PET polymer is made with chemical recycled raw materials such as used polyester fibers.

Versatile fineness

Wide  range  of  fineness,  from 33-330 decitex, *and filament  yarn processing is possible.

Highly practical

Very stretchable and dyeable, equivalent to those of petroleum-derived materials, and soft texture.

*Thread thickness measured in grams per 10,000m

In  recent  years, demands have  been growing  for  materials  offering functionality  and comfort, such  as  stretch ability and  soft  textures.  Also, users  are  seeking eco-friendly fabrics made with recycled and plant-derived materials.

Teijin   Frontier’s   existing S/S   conjugated   fiber comprises   a   highly   stretchable SOLOTEX®PTT-fiber polymer  made  with  about  40%  plant-based  raw  materials  and PET  made  of  recycled  raw materials. The  newest  version, SOLOTEX®ECO-Hybrid, solvesthe  problem  of achieving a  consistent  crimp  structure in  an eco-friendly S/S conjugated fibermade with recycled PET.

VAUDE eliminates PFAS from all products
