Cashmere fiber dyeing method for improving wash-resistant firmness

Abstract

The invention belongs to the technical field of cashmere fiber dyeing, and particularly relates to a cashmere fiber dyeing method for improving the wash-resistant firmness. The method comprises the steps of cashmere fiber pretreatment, plasma treatment, soaking and alkaline pectinase solution spray coating after cold storage. Compared with the prior art, the method has the following advantages that the cashmere fiber is pretreated; the softening, bleaching and sterilization effects can be achieved; the subsequent coloring uniformity can be improved; after the drying, plasma treatment is performed, so that the scale form structure on the surface of the cashmere fiber can be changed; the cashmere fiber is enhanced; the distribution is realized in the dyeing process; the ultrasonic treatment is performed, so that the dyeing rate can reaches 97 percent or higher; the color fading cannot easily occur; the dyeing process is simple; the damage to the cashmere fiber is small; after the cold storage treatment, the treatment is performed by the alkaline pectinase, so that hollow groove positions of the cashmere fiber scales can be filled; a reticular crosslinking film structure can be formed, so that the dyed finished product has the vivid and full color and luster; meanwhile, the color fastening effect is further enhanced; the handfeel of the fiber is improved.

Description

technical field [0001] The invention belongs to the technical field of cashmere fiber dyeing, and in particular relates to a cashmere fiber dyeing method for improving washing fastness. Background technique [0002] Cashmere is usually purely spun or blended with fine wool. The cashmere products made are expensive, feel good, and beautiful. Light yellow or yellow, especially the hair tips on the back of sheep are darker, even brown or brownish black, some parts of the fleece are also yellower due to bacterial stains, urine stains, etc., which directly affects the whiteness of pure white products Appearance quality indicators such as color and luminosity, and whether these resistant wools can be put into production is a question of whether resources can be effectively used, so further research is needed. Contents of the invention [0003] The purpose of the present invention is to provide a kind of cashmere fiber dyeing method that improves washing fastness to existing pro...
