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.

Teijin announces availability of DPP-compliant products aligned with Europe’s ESPR Environmental Regulation

Teijin Limited announced today that it has started rolling out initiatives to enable aramid fibers and carbon fibers to be accompanied by Digital Product Passport (DPP) technology, which enhances supply chain transparency by verifying the origins of materials and supporting sustainability claims. The company is using the supply chain traceability system from Netherlands-based Circularise B.V., in which Teijin has invested since November 2024, to develop DPPs for each product.

Teijin Carbon showcases new eco-friendly Tenax Next™ R2S 513 6mm short carbon fiber at JEC World 2025

Teijin Carbon, a leading manufacturer of carbon fiber products, is presenting its latest development in sustainable materials at JEC World 2025 (hall 6, G22). New Tenax Next™ R2S 513 6mm is a short carbon fiber product in rice-shaped form for reinforcing thermoplastic compounds that not only offers exceptional performance characteristics but also reinforces the company’s commitment to environmental responsibility and circularity.

Teijin to invest in Circularise B.V. and adopt its supply chain traceability platform to promote the Circular Economy

Teijin Limited announced today that it will invest in Circularise B.V., a company based in The Hague, Netherlands, which develops product traceability management systems using blockchain technology. Teijin will also implement Circularise’s software to improve visibility into its global supply chain. Circularise’s proprietary “Smart Questioning”(*) solution, which utilizes Zero-Knowledge Proof (ZKP) technology, provides both anonymity and transparency to ensure a highly reliable product traceability system.

Advanced Recycling Conference 2026 to showcase innovations – Call for abstracts

The call for abstracts is now open for the Advanced Recycling Conference (ARC) 2026, taking place on 17–18 November 2026 in Cologne, Germany, and online. Europe’s leading platform for advanced recycling brings together hands-on solutions and cutting-edge research on recycling technologies for various waste streams like plastics, polymers, textiles or automotive, highlighting progress towards a circular renewable carbon economy.

Europe needs tipping point to scale textile-to-textile recycling, BCG and ReHubs say

A new report from Boston Consulting Group (BCG) and ReHubs, titled “Advancing Textile Circularity – Europe’s textile waste challenge: Scaling Textile-to-Textile requires enabling mechanisms”, highlights the urgent need for systemic action to tackle Europe’s growing textile waste and scale a circular textile economy.
