Overview

On October 2, 2025, Teijin Frontier Co., Ltd. introduced THERMOFRONT™, a new master brand of sustainable, high-performance sheet insulation products designed to deliver exceptional warmth. The innovative insulation incorporates over 70% ECOPET® — Teijin Frontier’s own recycled polyester fiber — blended with hollow cross-sectional fibers and advanced raw materials to enhance thermal performance. THERMOFRONT™ targets applications spanning sportswear, outdoor apparel, and casual wear, meeting rising consumer demand for warmth, comfort, and sustainability.

Teijin Frontier is launching three initial THERMOFRONT™ sub-brands:

• THERMOFRONT™ OA: Features OCTAIR™, an 8-fin hollow cross-sectional staple fiber, combined entirely with recycled polyester for lightweight bulkiness and lasting thermal insulation.
• THERMOFRONT™ SL: Uses SOLOTEX®, a polytrimethylene terephthalate (PTT) fiber with spring-like molecules, blended with AEROCAPSULE® γ ECO hollow fibers, offering softness, shape retention, and superior warmth.
• THERMOFRONT™ BE: Combines BEMBERG® regenerated cellulose cupro fiber with AEROCAPSULE® γ ECO fibers to provide moisture control and comfort, with up to 97% recycled and regenerated content.

The products will be available domestically and internationally starting October 7, 2025, targeting the Autumn/Winter 2026 season for outdoor, sports, and casual wear markets.
