Teijin Frontier’s New High-stretch SOLOTEX® ECO-Hybrid Fiber
Made with Plant-derived and Recycled Materials
Tokyo, Japan, June 30, 2020 --- Teijin Frontier Co., Ltd., the Teijin Group's fibers andproducts converting company, announced today its new SOLOTEX® ECO-Hybrid
high-stretch side-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 crimp yarn.
SOLOTEX® ECO-Hybrid represents a new line in Teijin Frontier’s polytrimethylene
terephthalate (PTT) fiber SOLOTEX® family. SOLOTEX® ECO-Hybrid filament yarn andtextile will be introduced as a featured product for 2020 autumn/winter fashion apparel,
offering many possibilities for enhanced sportwear, uniforms and more. Annual sales ofSOLOTEX® ECO-Hybrid are expected to grow from JPY 500 million in 2020 to JPY 1.5billion in 2022 (filament yarn equivalent).
Key Features of SOLOTEX® ECO-Hybrid
Extra stretchability achieved with new technology for conjugating PTTPolymers

polymer and polyethylene terephthalate (PET) polymer made withchemically recycled raw material, which are then processed to create acrimp structure.

Filamentproduction

Crimp structure is equivalent to that of petroleum-derived rawmaterials.
Dyeability achieved with optimized yarn-making conditions.

Chemically recycled PET

Plant-derived PTT

PET polymer is made with chemical recycled raw materials such as
used polyester fibers.

Versatile finenessHighly practicalWide range of fineness, from 33-330 decitex,* and filament yarnprocessing is possible.

*Thread thickness measured in grams per 10,000m

In recent years, demands have been growing for materials offering functionality andcomfort, such as stretchability 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 andPET 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/Sconjugated fiber made with recycled PET.
