Dyeing process of silk knitted fabric active dye

Abstract

The invention discloses a dyeing process of a silk knitted fabric active dye. The dyeing process of the silk knitted fabric active dye comprises the steps of dyeing, fixing color, rosining, soaping, washing in hot water, washing in cold water and drying. Silk knitted fabrics are dyed by active dyes so that color is bright and dye fastness is good; the process is simple and convenient; silk abrasion caused by high-temperature dyeing on the silk knitted fabrics can be avoided.

Description

[0001] technical field [0002] The invention belongs to the dyeing process of knitted fabrics, in particular to a reactive dye dyeing process of real silk knitted fabrics. [0003] Background technique [0004] Silk knitted fabrics have long been dyed with acid or neutral dyes. The silk knitted fabrics dyed with acid dyes are bright in color, but the wet fastness is poor. The wet fastness of silk knitted fabrics dyed with neutral dyes is better, but the color is not bright enough. [0005] Contents of the invention [0006] In order to overcome the above-mentioned defects in the prior art, the object of the present invention is to provide a reactive dyeing process for real silk knitted fabrics, which has bright color and good color fastness. [0007] The reactive dyeing process of real silk knitted fabrics provided by the invention has the following steps: [0008] (a) Dyeing: put the silk knitted fabric into the dye solution containing 8-10 g / L of X-type reactive dye...
