Problems solved by technology

Sorghum fiber can be blended with cotton fiber, so that the resulting blended fabric has the advantages of both fibers, but the difference in properties of the two fibers makes the dyeing process of the blended fabric more complicated. The traditional dyeing process makes the sorghum fiber cotton blended fabric The same color is poor

Abstract

The invention discloses a dyeing method of a protein fiber cotton blended fabric, and belongs to the field of spun-dyed fabrics. The dyeing method of the protein fiber cotton blended fabric comprisesthe following steps that cotton fibers are pretreated with a sodium hydroxide solution, washed to be neutral and dried; protein fibers are pretreated with a weak acid resist agent and dried; the pretreated cotton fibers and the pretreated protein fibers are subjected to scutching and carding procedures and then are mixed and drawn, and the protein fiber cotton blended fabric is obtained through aroving frame and a spinning frame; and the protein fiber cotton blended fabric, a neutral dye, a dyeing accelerant and a color fixing agent are put into a constant-temperature water bath kettle filledwith water for dyeing and color fixing, and water washing, soaping and drying are performed to obtain a dyed protein fiber cotton blended fabric. According to the invention, the union dyeing propertyof the blended fabric is improved.

Description

technical field [0001] The invention belongs to the field of spinning and dyeing fabrics, and more specifically relates to a method for dyeing protein fiber cotton blended fabrics. Background technique [0002] Protein fiber is a kind of green fiber that is not often used in industry. At present, there are relatively few industrial utilization means and methods for sorghum fiber. Sorghum fiber can be blended with cotton fiber, so that the resulting blended fabric has the advantages of both fibers, but the difference in properties of the two fibers makes the dyeing process of the blended fabric more complicated. The traditional dyeing process makes the sorghum fiber cotton blended fabric The same color is poor. Contents of the invention [0003] 1. The technical problem to be solved by the invention [0004] The technical problem mainly solved by the invention is to provide a method for dyeing protein fiber cotton blended fabrics, in order to improve the same color of the...
