Embodiment 1

[0021] A kind of lace two-color thick strand thread of nylon wrapping cotton core thread is dyed, comprises the following steps:

[0022] First stage dyeing: At room temperature, add reactive dye (RedCDN) and first stage auxiliary agent (Yuanming powder, 90g / L) to the dyeing bath water that has not passed the lace two-color thick strands in sequence, and add the first stage auxiliary agent for 20 minutes. The middle dyeing solution is heated up at a rate of 2.5°C / min, and the temperature is raised to 80°C for dyeing bath. After 60 minutes in the dyeing bath at 80°C, soda ash (30g / L) is added, and the dyeing bath is continued for 30 minutes after adding soda ash;

[0023] The first stage of post-dyeing treatment: the dyeing solution is cooled to 50°C and released from the dyeing bath, and the lace two-color thick strands after the first dyeing are subjected to initial washing, soaping and post-washing;

[0024] The initial washing temperature is normal temperature and the time ...

Embodiment 2

[0028] A kind of lace two-color thick strand thread of nylon wrapping cotton core thread is dyed, comprises the following steps:

[0029] First stage dyeing: at room temperature, add reactive dye (BlueCDN) and first stage auxiliary agent (Yuanming powder, 80g / L) to the dyeing bath water that has not passed the lace two-color thick strands in sequence, add the first stage auxiliary agent for 25 minutes and then dye the pool The middle dyeing solution is heated up at a rate of 2°C / min, and the temperature is raised to 80°C for dyeing bath. After 50 minutes in the 80°C dyeing bath, soda ash (40g / L) is added, and the dyeing bath is continued for 40 minutes after adding soda ash;

[0030] The first stage of post-dyeing treatment: the dyeing solution is cooled to 50°C and released from the dyeing bath, and the lace two-color thick strands after the first dyeing are subjected to initial washing, soaping and post-washing;

[0031] The initial washing temperature is normal temperature ...

Embodiment 3

[0035] A kind of lace two-color thick strand thread of nylon wrapping cotton core thread is dyed, comprises the following steps:

[0036] First-stage dyeing: At room temperature, add reactive dye (Yellow HE-GG) and first-stage auxiliary agent (Yellow HE-GG) and first-stage auxiliary agent (Yellow HE-GG, 100g / L) to the dyeing bath water that has not passed through the lace double-color thick strands, and add the first-stage auxiliary agent for 30 minutes Finally, heat up the dye solution in the pool at a rate of 3°C / min, then heat up to 80°C for dyeing bath, add soda ash (20g / L) after 50 minutes in the dyeing bath at 80°C, and continue dyeing bath for 50 minutes after adding soda ash;

[0037] The first stage of post-dyeing treatment: the dyeing solution is cooled to 50°C and released from the dyeing bath, and the lace two-color thick strands after the first dyeing are subjected to initial washing, soaping and post-washing;

[0038] The initial washing temperature was at room t...

Abstract

The invention provides a lace bi-color thick plied yarn of a nylon-wrapped cotton-core thread and a dyeing method of the lace bi-color thick plied yarn. The dyeing method comprises first-section dyeing, first-section dyeing aftertreatment, second-section dyeing and second-section dyeing aftertreatment. According to the technical scheme, sufficient dyeing of a cotton thread in a plied yarn core isrealized mainly by changing a dyeing process and adding sequences of both of a dyeing dye and an additive. Sufficient permeation of the plied yarn is realized on the precise of neither prolonging thedyeing time nor increasing energy consumption. Stable colors are obtained, mutual color crossing is less and follow-up physical performance is favorable.

Description

technical field [0001] The invention relates to the field of printing and dyeing, in particular to a nylon-wrapped cotton core thread double-color thick-strand lace thread and a dyeing method thereof. Background technique [0002] In the dyeing field of lace fabrics, the two-color thick strands of lace are nylon-wrapped cotton core threads. In the dyeing and printing of lace two-color thick strands of nylon wrapped cotton core thread, the thick strands are difficult to penetrate in the conventional dyeing method, often the outer layer of nylon has been colored, but the inner layer of cotton thread is not fully dyed, resulting in poor printing and dyeing effects , more substandard products. Contents of the invention [0003] For this reason, need to provide a kind of dyeing method that can carry out sufficient dyeing to the lace two-color thick strand thread of nylon wrapping cotton core thread. [0004] In order to achieve the above object, the inventor provides a method...
