Abstract
Artificial hair having a look and feel that both are close in character to that of natural human hair, compared with artificial hair made from polyamide fibers, polyester fibers, acrylic fibers, etc., and which holds that character over time. By means of artificial hair composed of monofilaments containing poly(trimethylene terephthalate), in particular, by means of artificial hair composed of monofilaments containing poly(trimethylene terephthalate) having a denier of 22 to 333 dtex, a melting point of 225 to 235° C., a glass transition temperature of 45 to 80° C., the physical properties of elastic recovery, strength, stretch, and texture resemble natural human hair, and the occurrence of frizzes and gloss is kept under control.
