| Commercial stretch sports fabrics commonly combine PET filament with OP (polyurethane elastic yarn, or spandex). A four-way stretch construction provides close fit and freedom of movement, reducing tension and restriction during high-mobility activities. However, combining different polymers increases the complexity of material identification, sorting, and recycling at end of life. AFFT (Advanced Fully Functional Technology Inc.) Cool release TPEE Cooling Single Jersey Knit Fabric combines fine-denier, high-filament-count PET filament with TPEE polyester elastic yarn to create a comfortable polyester-family stretch system without OP. The fine PET filament provides lightweight, smoothness, and a soft hand, while TPEE delivers stable elongation and recovery. Together, they allow the single-jersey fabric to stretch comfortably during movement and reduce the sense of restriction against the body. Developed for a cooling touch, this series uses fine-denier filament, a smooth fabric surface, and single-jersey construction to balance a lightweight hand with a fresh sensation upon skin contact. Moisture management, quick drying, and UV-protection functions can also be incorporated. During dyeing and finishing, gentler heat-setting conditions can be planned according to the TPEE grade, blend ratio, and fabric construction. This helps control post-wash dimensional stability and fabric weight, providing brands with greater flexibility in silhouette, weight, and performance positioning. TPEE can also offer chlorine resistance, stable wash shrinkage, and elastic recovery. TPEE/elastoester systems produced through solvent-free melt extrusion can reduce the solvent use associated with conventional OP spinning. By avoiding OP and other non-polyester materials, Cool release TPEE Cooling Single Jersey Knit Fabric retains a more consistent material foundation for polyester-family recycling and textile-to-textile circular design. Suitable for underwear, T-shirts, lightweight active tops, sports pants, and dance or performance apparel, balancing comfortable stretch, lightweight cooling performance, and polyester-family circular design. |
