Process of making heat-retaining fibers

摘要

A method for making heat-retaining fiber and fabrics. According to the present invention, the white conductive particles and the white particles with good radiating efficiency of far-infrared radiation are added in fiber-forming polymers to obtain the mixed composition. The fiber and fabrics made of the mixed composition is characteristic of excellent effect of heat-retaining usable for the use of requiring good heat-retaining effectiveness.
