The dark cool fiber of the invention can be added with the nano-micro-particles by adopting the existing melt spinning technology. The preparation method of the dark cool fiber comprises the following steps:
A. preparing heat-insulating cool master batch from nano microparticles with a predetermined ratio and natural high molecular substances or synthetic high molecular substances; for example, the weight ratio of Fe to Cr is 24: 1 preparing heat-insulating cool master batch with natural high molecular substances or synthetic high molecular substances;
B. mixing the prepared heat insulating cool feeling master batch with other high molecular substance master batches or synthetic high molecular substance master batches uniformly;
C. mixing by a screw, and extruding by a spinning mechanism to obtain the dark cool fiber.
