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...

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...
