Abstract (en)
[origin: US4813969A] The invention deals with a process for production of synthetic hairs for use in wigs, hair pieces, etc. While the natural appearance of synthetic hair is retained, the synthetic hair has a high thermal resistance. In the process, individual hair is given a diffuse light refraction by altering its structure surface, by means of chemically disturbing the surface. The process is so conducted that the surface of a single filament polyester fiber is disturbed by means of a corrosive alkaline lye, in which the solution of about 20 g/l of natrium hydroxide works into the fiber at a temperature of 96 DEG C.-100 DEG C.
