October 13, 2025 | Tokyo – Teijin Frontier Co. Ltd., a leader in textile innovation, has launched THERMOFRONT™, a master brand of sustainable sheet insulation combining environmental responsibility with exceptional thermal performance. Aimed at outdoor, sports, and casual apparel markets, THERMOFRONT insulation features over 70% ECOPETⓇ recycled polyester fiber, augmented with advanced fiber technology to deliver superior warmth and comfort.

Sustainable Innovation Meets Performance

THERMOFRONT insulation leverages Teijin Frontier’s expertise in nonwoven fabric design and recycling technology.

The brand addresses rising consumer demand for eco-friendly yet high-functioning insulated outerwear shaped by diversified lifestyles and environmental awareness.

Product Lineup: Three Specialized Sub-Brands

ThermoFront™ launches with three sub-brands targeting the Autumn/Winter 2026 season:

• THERMOFRONT OA: Made entirely from recycled polyester using OCTAIR™, an 8-fin hollow staple fiber delivering lightweight bulk and sustained thermal performance through optimized sheet density.

• THERMOFRONT SL: Combines SOLOTEXⓇ (a spring-like polytrimethylene terephthalate fiber) with AEROCAPSULEⓇ γ ECO (three-hole hollow spiral polyester fiber) to provide softness, shape retention, and enhanced warmth.

• THERMOFRONT BE: Features a blend of BEMBERGⓇ (regenerated cellulose cupro fiber) and AEROCAPSULEⓇ γ ECO, offering superior moisture absorption and breathability. This product reaches 97% recycled and regenerated content, improving wearer comfort by controlling sweat-related humidity.
