Problems solved by technology

[0021] However, these fibers adhered to the silicone-based fiber treatment agent, although the smooth touch, combability, etc. are improved, but because the silicone-based fiber treatment agent itself is flammable, there are flame-retardant synthetic fibers. The problem of significantly lower flame retardancy

[0148] To the composition of polyethylene terephthalate, brominated epoxy-based flame retardant, organic particles, and inorganic particles in the proportions shown in Table 1 and Table 2, which is dried to a moisture content of 100 ppm or less, add the coloring agent 2 parts of polyester pellets PESM 6100BLACK (manufactured by Dainichi Seika Kogyo Co., Ltd., carbon black content 30%, polyester contained in component (A)) were dry-blended, supplied to a twin-screw extruder, and melt-kneaded at 280°C , After granulation, dry to a moisture content of 100ppm or less. Then, using a melt spinning machine, the molten polymer was sprayed from a spinneret having a circular cross-section orifice with a nozzle diameter of 0.5 mm at 280° C., cooled in air, and wound at a speed of 100 m / min to obtain a spun filament. The resulting spun yarn is drawn in a warm water bath at 80°C to become a 4-fold drawn yarn, wound at a speed of 30 m / min using a hot roll heated to 200°C, and heat-treated t...

[0180] Add polyester particles for coloring PESM 6100 BLACK to the composition of polyethylene terephthalate, brominated epoxy flame retardant, and inorganic fine particles in the ratio shown in Table 7, which has been dried to a moisture content of 100 ppm or less (manufactured by Dainichi Seika Kogyo Co., Ltd., carbon black content 30%, polyester contained in component (A)) 2 parts are dry-blended, supplied to a twin-screw extruder, melt-kneaded at 280°C, granulated, and dried To water content 100ppm or less. Then, using a melt-spinning machine at 280 ° C from having become Figure 8-10 The spinneret of the orifice of cross-sectional shape ejects molten polymer, air-cools, and is made into spun filament by winding at the speed of 100m / min. Draw the obtained spun filaments in a warm water bath at 80°C to become 4-fold drawn filaments, use a hot roll heated to 200°C, wind up at a speed of 30m / min, perform heat treatment, and adhere separately Fiber treatment agent KWC-Q (eth...

[0193] Add polyester particles for coloring PESM 6100 BLACK to the composition of polyethylene terephthalate, brominated epoxy flame retardant, and inorganic fine particles in the ratio shown in Table 9, which has been dried to a moisture content of 100 ppm or less (manufactured by Dainichi Seika Kogyo Co., Ltd., carbon black content 30%, polyester contained in component (A)) 2 parts are dry-blended, supplied to a twin-screw extruder, melt-kneaded at 280°C, pelletized, and dried To water content 100ppm or less. Then, using a melt-spinning machine at 280 ° C from having become Figure 8 , 9 The spinning head of the orifice of cross-sectional shape ejects molten polymer, air cooling, winds up by the speed of 100m / min, makes spinning filament. Draw the obtained spun filaments in a warm water bath at 80°C to become 4-fold drawn filaments, use a hot roll heated to 200°C, wind up at a speed of 30m / min, perform heat treatment, and adhere separately The fiber treating agent shown i...

Abstract

The invention relates to a flame-retardant polyester fiber for artificial hair which is produced by melt-spinning a composition comprising 100 parts by weight of at least one polyester (A) selected from among polyalkylene terephthalates and copolyesters comprising polyalkylene terephthalates as the main component and 5 to 30 parts by weight of a brominated epoxy flame retardant (b). Further, the invention relates to a flame-retardant polyester fiber for artificial hair as described above which has at least one modified cross section; a flame-retardant polyester fiber for artificial hair as described above which is a mixed fiber having a mixing ratio of circular cross section to modified cross section of 8 : 2 to 1 : 9; and a flame-retardant polyester fiber for artificial hair which is produced by making a hydrophilic fiber treatment adhere to the above polyester fiber and is excellent in smoothness to the touch, combing properties, and flame retardance.

Description

technical field [0001] This invention relates to flame-retardant polyester fibers for artificial hair formed from polyester and brominated epoxy-based flame retardants. More specifically, it relates to fibers for artificial hair that maintain fiber properties such as flame retardancy, heat resistance, strength, and elongation; and are excellent in setting properties, transparency, devitrification resistance, and combability. [0002] In addition, the present invention relates to fibers with special-shaped cross-sections, and more specifically, to fibers for artificial hair used for hair decoration such as wigs, braids, extension hair, etc., having luster, hue, feel, A bulky fiber with a different cross-section, and a fiber for artificial hair using the fiber with a different cross-section. [0003] In addition, the present invention relates to fibers for artificial hair having excellent smooth touch, combability and antistatic properties. Background technique [0004] Fibe...
