Embodiment 1
[0025] Take 97.9 parts of dried polyethylene terephthalate (percentage by weight, the same below), 2 parts of alumina powder, and 0.1 part of γ-glycidoxypropyltrimethoxysilane. After fully mixing, Extruded by twin-screw at 270°C, pelletized. The fiber cortex material is produced; take 84 parts of polyethylene, 4 parts of paraffin, and 12 parts of ethyl vanillin. After thorough mixing, extrude through twin-screw at 150° C., and granulate. The fiber core layer material is produced; after the obtained sheath-core material is fully dried, the winding yarn is spun with a skin-core composite spinning machine according to the weight ratio of the fiber skin to core of 7:3; , stretched 3 times, then relaxed heat-setting, cutting, to obtain the functional fiber. It was determined that the far-infrared emissivity of the obtained fiber was 82% (100° C.).
Embodiment 2
[0027]Take 92.6 parts of polypropylene with a melt index of 50, 4 parts of alumina powder, 3 parts of magnesium oxide powder, and 0.4 part of γ-methacryloxytrimethoxysilane. Twin-screw extrusion, granulation. Manufacture the fiber cortex material; take 87 parts of polypropylene (MI=25), 3 parts of ethylene-vinyl acetate (EVA), and 10 parts of vanillin. grain. Manufacture the fiber core layer material; after fully drying the sheath-core material, according to the sheath-to-core ratio of the fiber is 6:4, the coiled yarn is spun on the skin-core composite spinning machine; then the coiled yarn is heated at 65°C Draw down 4 times, can obtain described functional fiber. It was determined that the far-infrared emissivity of the obtained fiber was 86% (100° C.).
Embodiment 3
[0029] Get 95.8 parts of polytrimethylene terephthalate (PTT), 2 parts of magnesium oxide powder, 2 parts of zirconium dioxide powder, 0.2 part of N-beta-(aminoethyl)-gamma aminopropyltrimethoxysilane, After thorough mixing, extrude through twin-screw at 260°C and granulate. Manufacture the fiber cortex material; take 85 parts of low-melting point polyester (melting point: 150°C), 5 parts of polyethylene glycol, 5 parts of ethylene-vinyl acetate (EVA), 1 part of jasmonal, 2 parts of jasmone, and 3 parts of jasmonin Parts, after thorough mixing, twin-screw extrusion at 170°C, granulation. The fiber core layer material is produced; according to the sheath-to-core ratio of the fiber is 5:5, winding filaments are spun on the sheath-core composite spinning machine; then the fiber post-treatment is carried out according to Example 2 to obtain the functional fiber. It was determined that the far-infrared emissivity of the obtained fiber was 84% (100° C.).
