Embodiment 1

[0027] A kind of dyeing process of polyester blended fabric, its specific steps are as follows:

[0028] Fabric pretreatment: Put polyester blended fabrics into the cooking liquid, and add caustic soda solution to the cooking liquid, adjust the pH to 10, then heat the cooking liquid to 75°C, add 0.5% of the weight of the cooking liquid to the cooking liquid A mixture of sodium sulfite, sodium silicate and sodium phosphate, wherein the mass ratio of sodium sulfite, sodium silicate and sodium phosphate is 8:5:2, slowly heat up to 100°C and cook for 40 minutes, pick it up after cooking, and put it into sodium hypochlorite for bleaching Bleaching in liquid for 50min, washing with water after bleaching to obtain polyester blended fabric to be dyed;

[0029] Preparation of dye solution: add appropriate proportion of water and dye to the dye vat, and add caustic soda to adjust the pH to 8, then heat to 55°C, then add diffusing agent, surfactant, leveling agent to the dye vat, and ult...

Embodiment 2

[0033] A kind of dyeing process of polyester blended fabric, its specific steps are as follows:

[0034] Fabric pre-treatment: put polyester blended fabric into the cooking liquid, and add caustic soda solution to the cooking liquid, adjust the pH to 10, then heat the cooking liquid to 75°C, add 0.6% of the weight of the cooking liquid to the cooking liquid A mixture of sodium sulfite, sodium silicate and sodium phosphate, wherein the mass ratio of sodium sulfite, sodium silicate and sodium phosphate is 8:5:2, slowly heat up to 95°C and cook for 40 minutes, pick it up after cooking, and put it into sodium hypochlorite for bleaching Bleaching in liquid for 50min, washing with water after bleaching to obtain polyester blended fabric to be dyed;

[0035] Preparation of dye solution: add appropriate proportion of water and dye to the dye vat, and add caustic soda to adjust the pH to 8, then heat to 55°C, then add diffusing agent, surfactant, leveling agent to the dye vat, and ultr...

Embodiment 3

[0039] A kind of dyeing process of polyester blended fabric, its specific steps are as follows:

[0040] Fabric pre-treatment: Put polyester blended fabric into the cooking liquid, add caustic soda solution to the cooking liquid, adjust the pH to 8, then heat the cooking liquid to 75°C, add 0.5% of the weight of the cooking liquid to the cooking liquid A mixture of sodium sulfite, sodium silicate and sodium phosphate, wherein the mass ratio of sodium sulfite, sodium silicate and sodium phosphate is 8:5:2, slowly heat up to 95°C and cook for 40 minutes, pick it up after cooking, and put it into sodium hypochlorite for bleaching Bleaching in liquid for 50min, washing with water after bleaching to obtain polyester blended fabric to be dyed;

[0041] Preparation of dye solution: Add appropriate proportion of water and dye to the dye vat, and add caustic soda to adjust the pH to 10, then heat to 55°C, then add diffusing agent, surfactant, leveling agent to the dye vat, and ultrason...

Abstract

The invention provides a dyeing process of a dacron blended yarn weaved fabric. The dyeing process comprises the following four steps of conducting pretreatment on the fabric; feeding the dacron blended yarn weaved fabric into cooking liquor, adding a caustic soda solution to the cooking liquor, adding a mixture of appropriate sodium sulfite, sodium silicate and sodium phosphate into the cooking liquor, cooking the fabric, fishing up the fabric and then feeding the fabric into bleaching liquid to be bleached; preparing dye liquor; adding clear water and dye into a dye vat, adding caustic soda,heating to 50-60 DEG C, adding a dispersing agent, a surface active agent and a dye leveler into the dye vat, and then conducting ultrasonic dispersion treatment; and dyeing, washing and drying the fabric. According to the dyeing process, impurities on the surface of the pretreated fabric are effectively removed so that the fabric is colored more easily, and the color fastness of the colored fabric is higher. Moreover, in the dye liquor, the fabric is dyed at the two different temperature stages of medium-temperature coloring and high-temperature coloring, the temperature rising and falling rate is strictly controlled, and therefore, the dyeing effect is better.

Description

technical field [0001] The invention relates to the technical field of dyeing of fabrics, in particular to a dyeing process of polyester blended fabrics. Background technique [0002] Polyester fabric is a kind of chemical fiber clothing fabric widely used in daily life. It has high strength and elastic recovery ability, so it is durable, wrinkle-resistant and non-ironing. However, polyester fabrics also have poor hygroscopicity, feel stuffy when worn in summer, and are prone to static electricity in winter. Therefore, although these fabrics can basically meet people's needs. [0003] Polyester blended fabric is a kind of fabric that is more popular in recent years. It is made of polyester fabric as the main body and a variety of fabrics of different materials. It not only has the advantages of polyester fabrics, but also completely overcomes the shortcomings of polyester fabrics. However, in the process of dyeing polyester blended fabrics, there are some problems. For exam...
