Heat-insulating dark cool-feeling textile and dark cool-feeling fiber thereof

Abstract

A heat-insulating dark cool-feeling textile and a dark cool-feeling fiber thereof are provided. The dark cool-feeling fiber is formed by adding to the fiber nano microparticles which account for 0.05-5 wt % of the total weight of the textile fiber. The particle size of the nano microparticles is 300-1,800 nm, and the material of the nano microparticles is selected from two or more of iron, copper, nickel, cobalt, and chromium. The dark cool-feeling fiber is suitable for knitting or weaving to obtain a heat-insulating dark cool-feeling textile.
