Embodiment 1-3
[0066] 100 parts by weight of the PPS resin shown in the following Table 1 of MI was spun, and the amount of the silica matting agent was 0.5-1.0 parts by weight. The barrel temperature of the spinning machine was 290° C., the head temperature was set at 313° C., a 160-hole nozzle was used to prepare undrawn fibers, and the fibers were drawn 3.8 times using a roll drawing machine. The stretched fibers were heated using a roller heat treatment device at 240° C., and heated under tension. Immediately thereafter, 50 dtex synthetic hair fibers were prepared by relaxation and slight wave formation in a heating cabinet at 150° C. in the stress-free state.
