Silk gradient printing and dyeing process

Abstract

The invention discloses a silk gradient printing and dyeing process,and belongs to the field of silk printing and dyeing. The silk gradient printing and dyeing process comprises the following steps: S1: preparing a blank silk, pretreating the blank silk, and blending pigments, S2: using a plurality of arrayed spray coloring devices to produce a gradient of two or more colors on a fabric, S3: naturally drying, and removing moisture, so that a color transition effect is better and the cost is reduced, S4: after drying, performing steaming and fixing to improve the color fastness, then using silksol to treat the silk, and fixing the dye on the surface of the silk for color fixing, S5: performing washing, washing off dye and auxiliaries that are not dyed on the silk, and performing drying andfinishing on the color-fixed silk. According to the invention, the backfilling method can make the color transition effect better, save the dye, and can fix the dye on the silk surface, so that the dye is not easy to be detached, and the color fixing effect is improved.

Description

technical field [0001] The invention relates to the field of silk printing and dyeing, more specifically, to a silk gradient color printing and dyeing process. Background technique [0002] Silk is a hydrophobic fiber with a strong silk-like feel and bright luster, but it is not soft enough. It has a shiny effect, smooth, flat, and good elasticity. Gradient printing and dyeing of thin fabrics such as silk are mainly hung on star frames or square frames. The gradient color is carried out on the dyeing equipment. The color depth changes gradually with the length of the fabric. Most of the dyes used in the traditional silk printing and dyeing process are directly acidic and neutral dyes. When dyeing, the dye utilization rate is low. It is a waste of resources, and the color fixing effect is poor. It cannot be washed in the same bath with other clothes, and the color will become light and old due to fading. Contents of the invention [0003] 1. Technical problems to be solved...
