Problems solved by technology

[0002] At present, the composite ultrafine fibers of polypropylene and nylon are simply twisted from ultrafine polypropylene fibers and ultrafine nylon fibers. This simple twisted composite fiber brings certain difficulties to the post-processing due to the different fiber properties. In particular, the coloring properties of polypropylene fiber and nylon fiber are completely different, which brings great difficulties to the dyeing of composite fibers

Abstract

The invention discloses a colored polypropylene fiber and nylon composite superfine fiber. The colored polypropylene fiber and nylon composite superfine fiber comprises a colored superfine polypropylene fiber and nylon composite fiber, the superfine polypropylene fiber and nylon composite fiber is composed of a superfine polypropylene fiber as a core wire and a modified nylon fiber layer coating outside the core wire, the core dimension of the superfine polypropylene fiber is 1.5-0.5mum, the diameter of the coated composite fiber is 4-1mum, and the modified nylon is a nylon 6 melt containing a cerium oxide nanopowder material. The colored polypropylene fiber and nylon composite superfine fiber has good fiber characteristics of the polypropylene fiber, has a good resilience, and has an elastic recovery rate of above 90% when the elongation rate is 18%; and the colored polypropylene fiber and nylon composite superfine fiber also has a good colorizing characteristic of nylon, and the addition of the cerium oxide nanopowder material to nylon 6 greatly improves the activity of a dye when the nylon 6 is colorized, so the color fastness of the nylon 6 is improved, and the chromaticity of the nylon 6 to a plurality of dyes is further improved.

Description

technical field [0001] The invention relates to a fiber production technology, in particular to a production method of colored acrylic composite superfine fibers. Background technique [0002] At present, the composite ultrafine fibers of polypropylene and nylon are simply twisted from ultrafine polypropylene fibers and ultrafine nylon fibers. This simple twisted composite fiber brings certain difficulties to the post-processing due to the different fiber properties. In particular, the coloring properties of polypropylene fiber and nylon fiber are completely different, which brings great difficulties to the dyeing of composite fibers. Contents of the invention [0003] The purpose of the present invention is to provide a kind of uniform coloring in order to solve above-mentioned deficiencies in the prior art, the production method of the colored acrylic composite microfiber that color fastness is big. [0004] In order to achieve the above object, the present invention pr...
