Far Infrared Functional Textiles

The making of far-infrared (FIR) functional textile is a green method which the FIR function is induced by modifying the physical fibre structure during the spinning process. Better FIR absorptivity and emissivity performances can be achieved with more internal reflections. The production of the FIR textile is chemical-free, cost-competitive and eco-friendly. 


The FIR functional textile is a safe material for the application in areas such as thermal wear, active wear and sleepwear. The materials are able to improve blood circulation which the better circulatory flow can further enhance the bio-healthcare abilities such as keeping warm and increasing metabolic rate and blood oxygen level.

With significant results of enhancing emissivity efficiency and a higher level of temperature rise, the products made by the FIR functional fibres may provide a new healthcare alternative for enhancing daily functioning and well-being. Besides, it provides a sustainable way of producing personal health care apparel with bio-active functions and advantages induced by the FIR. 

Industry benefit

Compared to the conventional method, the highly efficient far infrared functional textiles are more cost-competitive and eco-friendly. The solution provides permanent far infrared function for heat preservation.

Consumers are increasingly concerned about how products are made. The FIR functional textiles are able to produce high value-added products through an innovative eco-production technology.

With these breakthroughs, this technology may fill the traditional products’ gap and gain a key position in the FIR functional textile market.

Technological breakthrough

The new production modifies the structure of fibre cross-session to achieve better FIR radiation absorptivity and emissivity, thus enhancing heat preservation of FIR textiles. The structural modification of fibre cross-section is applicable in all types of synthetic materials. The production method does not require any chemicals, additives, or coatings. As such, the function is more durable and able to endure numerous washes. Textile products made by such fibres are light in weight with a balance between the properties of moisture-thermal management and comfortability.
