Circu-Texfilm enables chemical recycling of PET/PU and PET/OP composite textiles without manual disassembly or decolorization. It converts mixed-color fabrics directly into polyurethane resins and waterproof-breathable films with uniform appearance and controlled properties. By optimizing PET/PU ratios, ITRI overcame PET’s high crystallinity and low breathability, resulting in high-performance, GRS- and bluesign®-certified films. Developed with eco-friendly functional textile manufacturer SINGTEX, Circu-Texfilm provides the world’s first textile-to-textile circular pathway that transforms waste fabrics into advanced apparel materials.
