Abstract
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.
Claims14
A process for making heat-retaining fibers, comprising:
- adding (1) 0.05-20 wt % of white conductive particles, and (2) 0.1-20 wt % of white particles with good radiating efficiency of far-infrared radiation into the fiber-forming polymer to obtain a mixed composition, wherein the total amount of said two types of particles are under 20 wt %;
- and
- melting and drawing the mixed composition with one extruder to obtain heat-retaining filaments or heat-retaining staple fibers.
