Dyeing Process of Silk Interwoven Jacquard Fabric

Abstract

The invention discloses a process for dyeing a silk interwoven jacquard fabric, belonging to the field of silk interwoven jacquard fabric dyeing technology. The process comprises the steps of dye fixing, primary washing, soaping, secondary washing and cylinder discharge and drying, wherein in the dye fixing step, the pretreated silk interwoven jacquard fabric is put into an active dye solution and dyed by adopting a jig dyeing method at 80-85 DEG C for 60-200 minutes; the active dye solution is obtained by mixing 1-5% owf of lanasol dye, 1-5% owf of HE type dye, 20-50g / L of anhydrous sodium sulphate, 5-20g / L of sodium carbonate and water. The process disclosed by the invention can be used for realizing bath dyeing when silk fibers and cellulose fibers in the silk interwoven jacquard fabric are dyed with different colors respectively, the color fastness of the obtained silk interwoven jacquard fabric with the double-color effect can reach the two-bath dyeing fastness, meanwhile, energy is saved, emission is reduced, and the process time is obviously shortened.

Description

technical field

[0001] The invention relates to a silk interwoven jacquard fabric dyeing process, which belongs to the technical field of silk interwoven jacquard fabric dyeing. Background technique

[0002] Silk interwoven jacquard fabric can not only reflect the softness and smoothness of silk, but also reflect the close fit and comfort of cellulose fibers, and improve the taste and grade of fabrics. Different from the design that silk fiber and cellulose fiber can only be dyed in the same color in ordinary silk-cotton interwoven fabrics, there is also a design of two-color silk interwoven jacquard fabrics in silk interwoven jacquard fabrics. Two-color silk interwoven jacquard fabric is designed by dyeing silk fiber and cellulose fiber with different colors respectively, that is, one color is dyed on silk fiber and another color is dyed on cellulose fiber. The design of the two-color silk interwoven jacquard fabric can make the jacquard area on the silk interwoven jacquar...
