Problems solved by technology

Grooves are formed on the surface of the fiber after reducing the amount of alkali, resulting in poor coloring rate of the grooves formed on the surface of the fiber during subsequent dyeing, and the dye is not easy to be dyed in the gaps in the grooves, which eventually leads to the overall dyeing of the strong twisted polyester fabric Low rate

Embodiment 1

[0046] refer to figure 1 , a dyeing process of strong-twisted polyester cloth, the selected strong-twisted polyester gray cloth (hereinafter referred to as gray cloth) is processed in the following steps:

[0047] S1: Preshrink the gray fabric to be dyed. Place the gray cloth in the high temperature and high pressure overflow dyeing machine, and then add sodium hydroxide solution in the high temperature and high pressure overflow dyeing machine for pre-shrinking treatment. The concentration of sodium hydroxide is 4-6g / L, and the temperature is controlled at 110°C. The time is 40 minutes. Wash twice after shrinking.

[0048] S2: Presetting the gray cloth after S1 treatment. Put the gray cloth into the heat-setting machine, adjust the temperature in the heat-setting machine to 180°C for 5 minutes, and then wait for the gray cloth to cool to room temperature (25°C).

[0049] S3: reducing the amount of alkali on the gray cloth after S2 treatment. The gray cloth is put into th...

Abstract

The invention relates to the technical field of textile processing, and discloses a dyeing technology of heavy twisting polyester fabrics. Gray fabrics are processed by adopting a processing method. The processing method comprises the following steps that S1, the gray fabrics are subjected to pre-shrinking; S2, the preshrunk gray fabrics are subjected to one-time presetting; S3, after one-time presetting, the gray fabrics are subjected to alkali amount reduction; S4, after alkali amount reduction, the gray fabrics are subjected to washing and neutralizing; S5, after washing and neutralizing, the gray fabrics are dyed; S6, the dyed gray fabrics are subjected to deep dyeing, wherein deep dyeing comprises the following steps that a, dye liquid for dyeing in the S5 is used, and the gray fabrics are subjected to continuous flushing dyeing at high temperature; b, after flushing dyeing, the temperature is preserved; c, after temperature preservation, the temperature is reduced to the indoor temperature; S7, after deep dyeing, the gray fabrics are subjected to overflow-water washing; S9; after overflow-water washing, the gray fabrics are subjected to setting; after setting in the S9, the dyed heavy twisting polyester fabrics are obtained. Through the above-mentioned dyeing technology, the dye-uptake rate of the integral heavy twisting polyester fabrics is increased ultimately.

Description

technical field [0001] The invention relates to the technical field of textile processing, more specifically, it relates to a dyeing process of strongly twisted polyester cloth. Background technique [0002] Polyester is a synthetic fiber that is widely used in textiles and has excellent comprehensive properties. Strong-twisted polyester fabrics have high requirements for the selection of materials, the change of twist and twist direction, the time and temperature of thread setting, the tension and uniformity of weaving threads, etc., and the production has certain technical difficulties. In recent years, the use of shuttleless looms, the popularization of two-for-one twisters, and the maturity of alkali reduction technology have provided necessary conditions for the development of strong-twisted polyester fabrics, and also provided technical guarantees for stable product quality. [0003] There are many types of strong-twisted polyester, but they all have common characteri...
