Problems solved by technology

[0003] Polyester cotton is a kind of blended fabric, including polyester and nylon. Due to the large difference between polyester and nylon, the two-bath two-step dyeing process is usually used in the dyeing process. This process has high energy consumption and more sewage discharge. , low output and poor benefit
At present, there is still a lack of better polyester-cotton dyeing methods, so it is necessary to develop a dyeing process for polyester-cotton fiber fabrics with energy saving, emission reduction and good dyeing effect.

Embodiment 1

[0032] A kind of dyeing process of polyester-cotton fiber fabric, comprises the following steps:

[0033] (1) Pre-setting: Pre-setting the fiber fabric through a pre-setting machine. During the pre-setting process, the setting temperature is 160°C, the speed is 10m / min, and the overfeed is 5%;

[0034] (2) Pre-treatment: Pre-treat the pre-shaped fiber fabric with a pre-treatment solution, specifically using a softener triethanolamine stearate quaternary ammonium salt 4 g / L, an emulsifier BP 1.5 g / L, and a penetrant JFC 3 g / L, accelerator 1227 1 g / L, soda ash 2 g / L, 60% hydrogen peroxide 2 g / L, treat in a water bath at 30°C for 2-3 min, the bath ratio is 20:1, then heat up in the water bath, heat up The speed is 2.5°C / min. When the temperature rises to 98°C, it is kept at this temperature for 30 minutes, and then the temperature of the water bath is lowered at a speed of 1.5°C / min. When the temperature drops to 60°C, the treated wastewater is discharged and re- Just inject wat...

Embodiment 2

[0043] A kind of dyeing process of polyester-cotton fiber fabric, comprises the following steps:

[0044] (1) Pre-setting: Pre-setting the fiber fabric through a pre-setting machine. During the pre-setting process, the setting temperature is 160°C, the speed is 13m / min, and the overfeed is 8%;

[0045] (2) Pre-treatment: The pre-formed fiber fabric is pre-treated with a pre-treatment solution, specifically using a softener triethanolamine stearate quaternary ammonium salt 5 g / L, an emulsifier BP 2.5 g / L, and a penetrant JFC 3.5 g / L, accelerator 1227 1.5 g / L, soda ash 2.5 g / L, 60% hydrogen peroxide 2.5 g / L, treat in a water bath at 30°C for 2-3 minutes, the bath ratio is 20:1, and then heat up in the water bath, then heat up The speed is 2.8°C / min. When the temperature rises to 98°C, it is kept at this temperature for 35 minutes, and then the temperature of the water bath is lowered at a rate of 2°C / min. When the temperature drops to 60°C, the treated wastewater is discharged a...

[0054] A kind of dyeing process of polyester-cotton fiber fabric, comprises the following steps:

[0055] (1) Pre-setting: Pre-setting the fiber fabric through a pre-setting machine. During the pre-setting process, the setting temperature is 160°C, the speed is 15m / min, and the overfeed is 10%;

[0056] (2) Pre-treatment: The pre-formed fiber fabric is pre-treated with a pre-treatment liquid, specifically, the softener triethanolamine stearate quaternary ammonium salt 6 g / L, the emulsifier BP 3.5 g / L, the penetrant JFC 4 g / L, accelerator 1227 2 g / L, soda ash 3 g / L, 60% hydrogen peroxide 3 g / L, treat in 30°C water bath for 2-3 min, bath ratio is 20:1, water bath and then heat up, heat up The speed is 3°C / min. When the temperature rises to 98°C, it is kept at this temperature for 40 minutes, and then the temperature of the water bath is lowered at a speed of 2.5°C / min. When the temperature drops to 60°C, the treated wastewater is discharged and re- Just inject water;

Abstract

The invention provides a dyeing process of a polyester cotton fiber fabric. The dyeing process comprises the following steps of preforming, pretreatment, drying, dyeing, washing, soaping, color fixing, drying, forming and winding. According to the dyeing process, a high-temperature leveling agent is added during dyeing, so that the problem that level dyeing effect and penetration dyeing effect are affected and even generate color dots and color patches occur caused by gathering of dyes because the heat stability resistance of fuel is reduced due to temperature increase is avoided, and the dyeing effect is good; the temperature is increased in a stepped progressive mode in the dyeing procedure, and the temperature increase and decrease velocity and the dyeing time are strictly controlled, so that high dyeing fastness, dyeing uniformity and good dyeing stability of the polyester cotton fiber fabric are achieved; the dyes with single property are not used and dispersed dyes and neutral dyes are compounded in the dyeing procedure, and the dispersed dyes and the neutral dyes supplement each other, so that good dyeing fastness is achieved; the traditional two-bath two-step method dyeing is abandoned, and the one-bath one-step method dyeing is adopted, so that the energy is saved, and the emission amount is reduced.

Description

technical field [0001] The invention relates to the field of chemical fibers, in particular to a dyeing process for polyester-cotton fiber fabrics. Background technique [0002] Chemical fibers are fibers with textile properties that are made from natural polymer compounds or artificially synthesized polymer compounds through the processes of preparing spinning dope, spinning and post-treatment. It has the advantages of light resistance, wear resistance, easy washing and drying, no mildew and no moths. Widely used in the manufacture of clothing fabrics, filter cloths, conveyor belts, hoses, ropes, fishing nets, electrical insulation wires, medical sutures, tire cords and parachutes, etc. [0003] Polyester cotton is a kind of blended fabric, including polyester and nylon. Due to the large difference between polyester and nylon, the two-bath two-step dyeing process is usually used in the dyeing process. This process has high energy consumption and more sewage discharge. , l...
