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.

Abstract

The present invention provides a polyphenylene sulfide synthetic hair filament. The synthetic hair filament comprises (A) a polyphenylene sulfide resin; and (B) an inorganic particle quencher additive, wherein said PPS resin melt index range is 60~110, wherein said inorganic quencher additive is added at 0.1~2.0 parts by weight on a 100 parts by weight PPS resin. The synthetic hair filament has a filament size of about 30 to about 80 dtex. The polyphenylene sulfide resin (A) has a p-phenylene sulfide repeating unit above 85% mole. The inorganic particle quencher additive may be of silicon dioxide, talc or the combinations thereof. A suitable inorganic particle quencher additive has an average diameter range of 0.01~3.0 [mu]m.

Description

technical field [0001] The invention relates to a polyphenylene sulfide synthetic hair fiber and a preparation method thereof. More particularly, the present invention relates to mixing a matting agent with a polyphenylene sulfide (PPS) resin to produce polyphenylene sulfide synthetic hair fibers and a method for preparing the synthetic hair fibers. Background technique [0002] Synthetic hair fibers used in wigs need and require hair fibers that are bright in color, natural in luster, light in weight, smooth to the touch, supple, can form and hold curls, and are flame retardant and heat resistant. As used herein, "flame retardancy" is described as being self-extinguishing and molten polymers are resistant to dripping. As used herein, "heat resistance" is described as the property of fibers that can withstand the normal temperatures of hair dryers and irons so that shrinkage or deformation due to normal temperatures does not occur. To replace the functions of natural hair,...
