Problems solved by technology

[0003] Dyeing is an important treatment process for chemical fibers. At present, acid dyes and metal complex dyes are usually used for dyeing in the dyeing process. Acid dyes and metal complex dyes have poor wet fastness in application performance, and their environmental protection performance is also poor. , thus limiting its use, and will inevitably be eliminated by the market in the long run

Embodiment 1

[0031] A chemical fiber dyeing process with anti-ultraviolet function, comprising the following steps:

[0032](1) Pretreatment: Pretreatment of chemical fiber, specifically: 1 g / L urea, 4.5 g / L TF-104M phosphate-free neutral deoiling spirit, 1 g / L sodium dodecylbenzenesulfonate, 60 % hydrogen peroxide 2 g / L, treated in a water bath at 30°C for 2-3 minutes, the bath ratio is 20:1, then the water bath is heated up at a rate of 2°C / min, when the temperature rises to 90°C, keep at this temperature After 30 minutes, the temperature of the water bath is lowered at a rate of 1°C / min. When the temperature drops to 60°C, the treated wastewater is discharged, and then re-injected with clean water and rinsed at room temperature until the lotion is neutral, and finally dried;

[0033] (2) Pre-setting: the pre-setting process is performed on the chemical fiber through the pre-setting machine. During the pre-setting process, the setting temperature is 160°C, the speed is 20m / min, and the o...

Embodiment 2

[0042] A chemical fiber dyeing process with anti-ultraviolet function, comprising the following steps:

[0043] (1) Pretreatment: Pretreatment of chemical fibers, specifically: urea 1.2 g / L, phosphorus-free neutral degreasing spirit TF-104M 5 g / L, sodium dodecylbenzenesulfonate 1.2 g / L, 60% hydrogen peroxide 2.5 g / L, treated in a 30°C water bath for 2-3 minutes, the bath ratio is 20:1, the water bath is then heated up at a rate of 2.5°C / min, when the temperature rises to 90°C, at this temperature Keep it for 35 minutes, then lower the temperature of the water bath at a rate of 1.5°C / min. When the temperature drops to 60°C, discharge the treated wastewater, then re-inject clean water and rinse at room temperature until the lotion is neutral, and finally dry it;

[0044] (2) Pre-setting: the pre-setting process is performed on the chemical fiber through the pre-setting machine. During the pre-setting process, the setting temperature is 165°C, the vehicle speed is 25m / min, and th...

Embodiment 3

[0053] A chemical fiber dyeing process with anti-ultraviolet function, comprising the following steps:

[0054] (1) Pretreatment: Pretreatment of chemical fibers, specifically: urea 1.5g / L, phosphorus-free neutral degreasing spirit TF-104M 5.5 g / L, sodium dodecylbenzenesulfonate 1.5 g / L , 60% hydrogen peroxide 3 g / L, treated in a 30°C water bath for 2-3 minutes, the bath ratio is 20:1, the water bath is then heated up at a rate of 3°C / min, when the temperature rises to 90°C, at this temperature Keep it at high temperature for 40 minutes, then lower the temperature of the water bath at a rate of 2°C / min. When the temperature drops to 60°C, discharge the treated wastewater, then re-inject clean water and rinse at room temperature until the lotion is neutral, and finally dry it;

[0055] (2) Pre-setting: the pre-setting process is performed on the chemical fiber through the pre-setting machine. During the pre-setting process, the setting temperature is 170°C, the speed is 30m / min...

Abstract

The invention provides a chemical fiber dyeing technology with the ultraviolet protection function. The chemical fiber dyeing technology comprises pretreatment, pre-shaping, dyeing, washing, soaping, color fixing, softening treatment, drying, shaping and rolling. The natural dyestuff of sophora flower bud is adopted, aluminum potassium sulfate dodecahydrate is used as a mordant, the dyeing effect is better, and the washability is greatly enhanced; meanwhile, due to the performance of the sophora flower bud, dyed chemical fiber has the good ultraviolet protection performance and the antibacterial and oxidation resistance; the washing technology and the color fixing technology are added, the dyeing firmness is good, green and environment-friendly and aldehyde-free TCD-R is adopted in the color fixing technology, and the chemical fiber obtained after color fixing is dried step by step, so that the firmness of the chemical fiber is greatly improved; the softening treatment technology is added, the fabric color firmness and flexibility are improved, the fabric roughness is lightened, and the fabric is fluffy and full of elasticity.

Description

technical field [0001] The invention relates to the chemical fiber field, in particular to a chemical fiber dyeing process with an anti-ultraviolet function. 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] Dyeing is an important treatment process for chemical fibers. At present, acid dyes and metal complex dyes are usually used for dyeing in the dyeing process. Acid dyes and metal complex dyes have poor wet fastness in application performance, and their environmental protec...
