Problems solved by technology

With the improvement of people's living standards, the requirements for clothing and fabrics are getting higher and higher, but the fading of denim is a common problem at present
[0003] The fading of denim, first, the denim products become lighter and lighter after repeated cleaning, and the clothes look worn out and unattractive; secondly, due to the fading of denim, it is necessary to wash the clothes separately, which greatly increases the workload and wastes resources, waste of time

Embodiment 1

[0045] A non-bleaching denim printing and dyeing process, the gray fabric is elastic denim knitted fabric, comprising the following steps:

[0046] (1) Pre-treatment gray cloth: treat the gray cloth with alkali, refining agent and hydrogen peroxide, and dehydrate and shape it;

[0047] (2) Slurry printing: Prepare the printing paste, and its viscosity is controlled at 16000Pa·S. After the preparation is uniform, filter it with a 30-mesh screen, then filter it with a 55-mesh screen, pretreat it with ultrasonic waves for 60 minutes, and then use a flat screen printing machine Dyeing and printing, drying at 110°C;

[0048] (3) Steaming: After steaming at 110°C for 15 minutes, increase the temperature to 125°C for 8 minutes;

[0049] (4) Water washing: select a continuous rope washing machine, the first three are washed with cold water, the fourth is washed with hot water, the last two are washed with cold water, and the centrifuge is dehydrated;

[0050] (5) Soaking: Soak with ...

Embodiment 2

[0059] A non-bleaching denim printing and dyeing process, the gray fabric is elastic denim knitted fabric, comprising the following steps:

[0060] (1) Pre-treatment gray cloth: treat the gray cloth with alkali, refining agent and hydrogen peroxide, and dehydrate and shape it;

[0061] (2) Slurry printing: Prepare the printing paste, and its viscosity is controlled at 17000Pa·S. After the preparation is uniform, filter it with a 40-mesh screen, then filter it with a 60-mesh screen, pretreat it with ultrasonic waves for 80 minutes, and then use a flat screen printing machine Dyeing and printing, drying at 113°C;

[0062] (3) Steaming: After steaming at 113°C for 12 minutes, increase the temperature to 124°C for 9 minutes;

[0063] (4) Water washing: select a continuous rope washing machine, the first three are washed with cold water, the fourth is washed with hot water, the last two are washed with cold water, and the centrifuge is dehydrated;

[0064] (5) Soaking: Soak with ...

Embodiment 3

[0074] A non-bleaching denim printing and dyeing process, the gray fabric is elastic denim knitted fabric, comprising the following steps:

[0075] (1) Pre-treatment gray cloth: treat the gray cloth with alkali, refining agent and hydrogen peroxide, and dehydrate and shape it;

[0076] (2) Slurry printing: Prepare the printing paste, and its viscosity is controlled at 18000Pa·S. After the preparation is uniform, filter it with a 50-mesh screen, then filter it with a 65-mesh screen, pretreat it with ultrasonic waves for 80 minutes, and then use a flat screen printing machine Dyeing and printing, drying at 115°C;

[0077] (3) Steaming: After steaming at 115°C for 10 minutes, increase the temperature to 125°C for 8 minutes;

[0078] (4) Water washing: select a continuous rope washing machine, the first three are washed with cold water, the fourth is washed with hot water, the last two are washed with cold water, and the centrifuge is dehydrated;

[0079] (5) Soaking: Soak with ...

Abstract

The invention relates to a printing-dyeing technology for denim with fast color. Grey cloth adopts elastic denim knitted cloth. The printing-dying technology comprises the following steps: (1), pretreatment of the grey cloth; (2), paste preparation and printing; (3), ageing; (4), washing; (5), soaking; (6), washing and (7), shaping. According to technology improvement, printing paste is subjected to ultrasonic treatment after preparation, continuous ageing is performed at two different temperatures after printing, then the cloth is soaked and cleaned with sodium carbonate and saline water, and the denim is prepared. With application of the printing-dyeing technology, the dye-uptake of the cloth is improved, the viscosity of the printing paste is reduced, so that coloring is easier, obscure and three-dimensional effects of the colorful denim are obtained, the style of the denim product style is improved greatly, and the technology has high market competitiveness.

Description

technical field [0001] The invention relates to the technical field of knitted fabric printing and dyeing, in particular to a non-decolorizing denim printing and dyeing process. Background technique [0002] In modern life, denim is ubiquitous in people's lives. Denim has the advantages of natural color, comfortable wearing, wear resistance and good elasticity, which are sought after by everyone, and often lead the fashion trend. Along with the raising of people's living standard, also more and more higher to the requirement of clothing and cloth, but the easy fading of denim is a ubiquitous problem at present. [0003] The fading of denim, first, the denim products become lighter and lighter after repeated cleaning, and the clothes look worn out and unattractive; secondly, due to the fading of denim, it is necessary to wash the clothes separately, which greatly increases the workload and wastes resources, waste of time. So it is particularly important to find a denim pri...
