[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 with other clothes in the same bath, and the color will become light and old due to fading

Embodiment 1

[0027] see figure 1 , a silk gradient color printing and dyeing process, comprising the following steps:

[0028] S1: Prepare gray silk first, perform fabric refining and bleaching pretreatment on it, refine it with alkali refining, use hydrogen peroxide as oxidant, bleach gray silk, facilitate later coloring, reduce its wastewater concentration, thereby reducing printing and dyeing The waste water produced in the waste water, and then the pigment is prepared, and the silk to be printed and dyed is soaked in warm water for 45 minutes and then taken out to color it;

[0029] S2: Carry out gradient coloring for silk, and adjust the concentration of dyeing liquid in the liquid spray shader by using the method of increasing the concentration increasing coefficient, which can improve the transition effect of dark and light colors, and use the liquid spray shader that can color silk in a small width range , combine multiple spraying liquid shaders in a certain order, adjust the con...

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...
