Problems solved by technology

For example, the Chinese patent discloses a preparation method of polyester fiber textile thread. This patent is to dye the polyester fiber after it is formed. The dyeing is difficult, and the subsequent processing technology is cumbersome, the cost is high and it is not environmentally friendly.
Chinese patent "Preparation method of colored flame-retardant matting hollow polyester filament", application number 200910303607.6, application date 2009-06-24, this patent solves the problem of difficult polyester dyeing
But the cost of preparing polyester filament according to the method in this invention is higher, after adding color masterbatch and delustering agent, cause the spinnability of polyester filament to deteriorate, resulting in poor product quality

Abstract

The invention relates to the technical field of a chemical fiber textile flame-retardant material, particularly to a preparation process of a colorful polyester fiber. The preparation process comprises the following steps: drying, grinding, mixing, melting, spinning, after-processing and shaping raw materials to obtain a finished product. The colorful polyester fiber prepared by adopting the process has good spinning property, good flame-retardant effect, high decomposition temperature, good heat stability and excellent dyeing property; the color is brighter compared with the ordinary dyeing fiber, and the color fastness is high.

Description

technical field [0001] The invention relates to the technical field of chemical fiber textile flame-retardant materials, in particular to a preparation process of colored polyester fibers. Background technique [0002] Most of the clothing, decorations and industrial products used in textile materials require that the textiles should have flame retardant properties, such as children's clothing, special industry clothing, textile decorations used in public places such as hotels and entertainment, and transportation. Textiles, packaging textiles, etc. Therefore, flame-retardant textile materials have broad market application prospects and requirements. Due to its excellent properties such as high strength, chemical resistance, good weather resistance, and good dimensional stability, polyester materials are currently the fiber variety with the largest production scale and output in chemical fibers, and it is also one of the fiber varieties with a wide range of applications. Ho...
