Problems solved by technology

[0010] However, since artificial hair requires high heat resistance, when these copolyester fibers are used as artificial hair, the amount of copolymerization must be large. As a result, the heat resistance of polyester is greatly reduced, and melt spinning is difficult. Occasionally, fire and combustion do not occur, but other problems such as melting and dripping occur
In addition, when compounding the above-mentioned phosphorus flame retardant, in order to express flame retardancy, its addition amount must be increased, and the sticky feeling caused by this will increase. In addition, the artificial hair made of the obtained polyester fiber , under the condition of heat history or high humidity, it is easy to have problems on the appearance of fibers such as devitrification
[0011] Therefore, the actual situation is to maintain the fiber properties of conventional polyester fibers such as flame retardancy, heat resistance, and elongation, and artificial hair excellent in fixability, drip resistance, transparency, and devitrification resistance is still did not receive

Embodiment 1～16

[0111] In the composition shown in Table 1, which is composed of polyethylene terephthalate dried to a moisture content of 100ppm or less, phosphorus-containing flame retardant, organic particles, and inorganic particles in the proportions shown in Table 1, polyester for coloring is added. Two parts of granule PESM6100 BLACK (manufactured by Dainichi Seika Co., Ltd., carbon black content 30%, containing polyester (A) component) were dry-blended, supplied to a twin-screw extruder, and melt-kneaded at 280° C. to produce After being granulated, it is dried to a moisture content of 100ppm or less. Then, with a melt spinning machine, at 280°C, the molten polymer is ejected from a spinning spinneret with a nozzle diameter of 0.5mm in a circular cross-section orifice at 280°C. Cool in a water bath, and wind up at a speed of 100 m / min to obtain an undrawn yarn. Stretch the obtained unstretched yarn in a hot water bath at 80°C to make a 4-fold stretched yarn, wind it with a heating ro...

Abstract

The present invention provides a common polyester fiber which maintains fiber physical properties such as heat resistance and elongation, and is excellent in flame retardancy, fixation, drip resistance, transparency, and devitrification resistance, and the fiber beauty is controlled Polyester fiber and its artificial hair. It consists of 100 parts by weight of polyester (A) composed of one or more of polyalkylene terephthalate polyesters and copolyesters mainly composed of polyalkylene terephthalate polyesters, and organic cyclic phosphorus compounds and / or a composition obtained by melt-kneading 2 to 20 parts by weight of a phosphate ester amide compound (B), and a composition in which organic microparticles (C) and / or inorganic microparticles (D) are mixed in the composition, by By melt spinning, a flame-retardant polyester-based artificial hair fiber having solved the above-mentioned problems was obtained.

Description

technical field [0001] The present invention relates to a flame-retardant polyester-based fiber for artificial hair comprising a composition obtained by melt-kneading a specific phosphorus-containing flame retardant in polyester. More specifically, it relates to a fiber for artificial hair that maintains fiber properties such as flame retardancy, heat resistance, and body strength, and is excellent in fixability, drip resistance, transparency, and devitrification resistance. Background technique [0002] Fibers composed of polyethylene terephthalate or polyester with polyethylene terephthalate as the main body have excellent heat resistance and chemical resistance due to their high melting point and high elastic modulus. Therefore, it is widely used in curtains, bedding fabrics, clothing materials, blankets, bed sheets, tablecloths, sofa releases, wall decoration materials, artificial hair, automotive interior decoration materials, exterior reinforcement materials, safety ne...
