Dyeing and finishing process of corn fibers and cotton blending and mixed fabrics

Abstract

The invention discloses a dyeing and finishing process of corn fibers and cotton blending and mixed fabrics, comprising the following steps: end stitching of greige cloth, pre-setting, pre-treatment, dyeing, dehydration, post finishing, and warehouse entry inspection. In the pre-setting process, the temperature is 120-130 DEG C and the time is 30-45 minutes; in the pre-setting process, the presetfabrics are placed in an overflow dying machine to conduct desizing and remove the hairiness on the surface of the fabrics; in the dying process, the corn fibers adopt middle temperature type and lowtemperature type dispersing dyes to conduct dying; and in the post finishing process, the dyed fabrics are placed in a 8-12g / L of hydrophilic amino-silicone softener for padding, and then the padded fabrics are dried and stentered and set at 100-120 DEG C. The dyeing and finishing process of corn fibers and cotton blending and mixed fabrics has good coloring rate, ensures the strength and feel ofcorn fibers, and also has significant impact on the industrial development of the textile industry.

Description

Background technique [0001] The invention relates to the textile field, in particular to a dyeing and finishing process of corn fiber and cotton blended and interwoven fabrics. Background technique [0002] Corn fiber is also called polylactic acid fiber and PLA fiber. It is a new type of polyester fiber made from corn, wheat and other starch raw materials through fermentation, polymerization, spinning and other processes. It is also commonly called polylactide fiber. It has biological Degradation characteristics, the degradation products are carbon dioxide and water, no pollution to the environment, it is a new type of environmentally friendly synthetic fiber that can be completely recycled naturally. [0003] Since Cargill-Dow launched polylactic acid fiber, people have never stopped studying it. Many excellent properties of polylactic acid fiber have stimulated its application in the field of fibers and nonwovens. Silk or multifilament, BCF with trilobal cross-section (u...

AI Technical Summary

Problems solved by technology

At present, although many other research institutions and textile printing and dyeing enterprises at home and abroad have carried out relevant research on the dyeing and finishing of corn fiber, the research on the dyeing and finishing technology of corn fiber blended (interwoven) fabrics is not deep enough.
