Problems solved by technology

Because this method adopts the post-finishing process, the microcapsule essence and the like are easy to fall off due to washing, etc., so the stability and durability of its fragrance function are poor
Within the scope known to the applicant, there is no bibliographical report on functional fibers with far-infrared health-care effects and aromatic smells

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, granulated. 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 a fiber skin-core weight ratio of 7:3; then the winding yarn is heated at a temperature of 95°C , 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.).

Abstract

The invention relates to a functional fiber and its manufacturing method, where the functional fiber has a skin-core structure, the weight ratio of skin to core 3 / 7 - 7 / 3; and the formula of the skin materials in weight percent comprises: skin polymer 91.6-97.6%, far infrared powder 2-8%, and coupling agent 0.1-0.4%; the skin polymer is one of PTT, PBT, PA-6, PET and PP with fusion index of 25-50; the coupling agent is one of gama-shink glycerol oxy propyl trimethoxy silane, gama-methyl propylene acyl oxy trimethoxy silane, N-beta-(amido ethyl)-gama amido propyl trimethoxy silane, and gama-amido propyl triethoxy silane; and the formula of the core-layer materials in weight percent comprises: core-layer polymer 88-99%, and flavor 1-12%; wherein the core-layer polymer is one of PE, PP and PET with melting point of 150-200 deg.C. The fiber of the invention has far infrared emissivity of 81-86%, very strong spicery and is a synthetic health functional fiber.

Description

technical field [0001] The present invention relates to chemical fiber and its manufacturing method technology, specifically a functional fiber with aromatic smell and far-infrared health care function and its manufacturing method technology. The IPC main classification number is proposed to be Int.Cl 7 D01F 2 / 08. Background technique [0002] Both far-infrared fiber and aromatic fiber are functional fibers that have a certain health care effect on the human body. A lot of researches have been done at home and abroad. Existing a large number of patent literature reports for far-infrared fiber, for example, Japanese Patent Laid-Open No. 1-24837 has introduced the method for adding far-infrared powder in polymer to prepare far-infrared fiber; The technology of adding far-infrared ceramic powder to make far-infrared health-care synthetic fibers; Chinese patent CN 1095118 also discloses a preparation method of far-infrared ceramic chemical fibers. There are also many patent ...
