Problems solved by technology

Before the gray cloth is dyed, there may be problems such as uneven distribution of various parts and different permeability of the cloth surface. Due to the constraints of various conditions, there are differences in the absorption of dyes, resulting in the color difference in the edge of the fabric.

Embodiment 1

[0025] A kind of fabric dyeing and finishing technology that prevents the difference in edge, comprises the following steps:

[0026] S1: Pre-type. Control the difference in moisture content between the left, middle, right and front, middle and back of the gray cloth to 2.5% before pre-setting. The first stage, width preservation, setting time is 5s, the setting temperature of the first part is 160°C, and the setting temperature of the second part is 185°C; the second stage, progressive stretching, the width stretching rate is 3.5%, and the setting time is 4s, the setting temperature is 195°C; the third stage, width preservation, the setting time is 3s, the setting temperature is 195°C; the fourth stage, progressive narrowing, the width shrinkage rate is 2%, the setting time is 3s, the setting temperature 195°C; the fifth stage, width preservation, setting time is 3s, setting temperature is 180°C;

[0027] Obviously, this embodiment may also include a subsequent dyeing proce...

Embodiment 2

[0029] A kind of fabric dyeing and finishing technology that prevents the difference in edge, comprises the following steps:

[0030] S1: Gray fabric pretreatment. After unwinding, cold stacking, and open-width washing, keep the moisture content difference between the left, middle, right and front, middle, and back of the cloth surface at 2.5%;

[0031] S2: Pre-type. The first stage, width preservation, the setting time is 10s, the setting temperature of the first part is 150°C, and the setting temperature of the second part is 180°C; the second stage, progressive tentering, the width stretching rate is 3%, and the setting time is 8s, the setting temperature is 190°C; the third stage, width preservation, the setting time is 5s, the setting temperature is 190°C; the fourth stage, progressive narrowing, the width shrinkage rate is 2%, the setting time is 5s, the setting temperature 190°C; the fifth stage, width preservation, setting time is 5s, setting temperature is 170°C;

Abstract

The invention relates to the field of textile fabrics, in particular to a fabric dyeing and finishing process for preventing color shading of the side and the center. According to the technical scheme, a segmented preset process is adopted, the internal stress of the fabric is relaxed after three times of width preservation, one time of width stretching and one time of width folding, the energy inthe fiber is reduced, the problem of the color shading of the side and the center generated in a subsequent dyeing and finishing process is effectively prevented, and the obtained fabric is pure andfull in color and excellent in color fastness.

Description

technical field [0001] The invention relates to the field of textile fabrics, in particular to a fabric dyeing and finishing process for preventing edge centering. Background technique [0002] In the process of fabric dyeing and finishing, various color differences often occur due to different weaving dyeing and finishing processes. Among them, color difference in the edge is one of the most common and extremely difficult problems in the printing and dyeing process. Before the gray cloth is dyed, there may be problems such as uneven distribution of various parts and different permeability of the cloth surface. Due to the constraints of various conditions, there are differences in the absorption of dyes, resulting in edge-to-edge color difference in the fabric. There are two ways to improve the color difference in the edge on the market. One is to strengthen the inspection of gray fabrics during pre-treatment, improve various pre-treatment processes, reduce the color differe...
