Far infrared (FIR) fabrics has a growing market for use in clothing and healthcare products for pain relief, muscle recovery, sleep improvement and body temperature regulation. Produced through structural modification of man-made fibres, our unique textile has a permanent FIR function that helps to increase blood microcirculation, enhance metabolism and enable thermal preservation. Through theoretical simulation and national standard assessment, it is proved to achieve higher FIR emission and better temperature preservation. In addition, this FIR textile demonstrates better quality in terms of weight, moisture management and wear comfort. It is also cost-effective and eco-friendly with no added chemicals.
