Abstract

The invention discloses colored micron filament composite superfine fiber and a preparation method thereof. The colored micron filament composite superfine fiber comprises the following components in parts by weight of 5-7 parts of colored master batch, 50-70 parts of polyester polymer and 20-50 parts of polyamide polymer. The composite fiber is characterized in that the polyester polymer is polyethylene glycol terephthalate or polybutylene terephthalate; and the polyamide polymer is one of nylon 6, nylon 66, nylon 46, nylon 610, nylon 612 and nylon 12. The composite fiber has the advantages that a melt spinning method is adopted, and the composite fiber has good fiber characteristics, good flexibility, good hygroscopicity and good air permeability. By adopting the mode of adding the colored master batch, the change of a melt spinning process is reduced to the greatest extent, the flexibility and diversity are realized, the characteristic that varieties are changed in time at any time is achieved, and the obtained colored superfine fiber product is small in chromatic aberration, good in color fastness, not easy to fade, easy to industrially produce, environmentally friendly and capable of reducing three-waste pollution.

Description

technical field [0001] The invention relates to the technical field of chemical fibers, in particular to a colored micron filament composite superfine fiber and a preparation method thereof. Background technique [0002] Due to the extremely fineness of ultra-fine fibers, the stiffness of the silk is greatly reduced, and the fabric feels extremely soft. The fine fibers can also increase the layered structure of the silk, increase the specific surface area and capillary effect, and make the internal reflection of the fiber more delicate on the surface. , so that it has a silky elegant luster, and has good moisture absorption and moisture dissipation. Most of the traditional industries use dyeing method to obtain colored microfibers, but this method not only has poor dyeing effect, but also causes certain environmental pollution. Contents of the invention [0003] The object of the present invention is to provide a kind of colored micro-filament composite superfine fiber wh...
