Description
Technical Field
The invention belongs to the technical field of energy conservation and emission reduction, and particularly relates to a short-process dyeing method for a brocade/ammonia high-elasticity fabric.
Background
The polyamide belongs to polyamide fiber, is the synthetic fiber produced in the earliest industrialization in the world, and still occupies an important position in the synthetic fiber till now. The nylon fiber has excellent physical performance, textile performance, chemical stability and many advantages of synthetic fiber, such as no-ironing, no-washing and wearing, good dimensional stability, small shrinkage, high weather resistance and the like.
The chinlon fabric has the characteristics of high strength, good elasticity, small specific gravity, good wear resistance and durability, mildew resistance, moth resistance and the like, so that the chinlon fabric is popular with consumers. The nylon/ammonia high-elastic fabric formed by interweaving nylon and high-proportion spandex (the content of the spandex is more than 10 percent and is usually 10 to 25 percent) is the preferred fabric for high-grade swimwear and yoga clothes.
Because the wet treatment fastness of chinlon dyed is poor, acid color fixation is needed, and in order to obtain a good color fixation effect, the traditional process firstly discharges liquid and then fixes color after dyeing (that is, other components do not influence the color fixation effect), so that the process is long, the efficiency is low, the water consumption is high, and the energy consumption is high.
At present, for 100% nylon fabric and common nylon/ammonia fabric (the content of spandex is not more than 10%, usually 5%), the direct color fixation without liquid discharge after dyeing can be realized according to the reports of documents, and the color fixation effect is basically equivalent to that of the traditional process.
However, no literature report that the brocade/ammonia high-elastic fabric is directly fixed without liquid discharge after dyeing is found.
In addition, for the nylon/ammonia high-elastic fabric, the traditional process has the following defects: for deep and bright color systems, the color fixing effect is poor, and the color fastness is not ideal.
Disclosure of Invention
The invention aims to solve the problems and provides a short-process dyeing method for brocade/ammonia high-elastic fabrics, which can obtain better color fixing effect after direct color fixing without discharging liquid after dyeing, and particularly has higher color fastness for dark colors and bright colors.

thirdly, dyeing the nylon/ammonia high-elasticity fabric, and directly performing acid color fixation without discharging liquid after dyeing; the acidic color fixing adopts DM-2537 acidic color fixing agent;
and fourthly, softening the nylon/ammonia high-elasticity fabric.
The refining treatment in the step I adopts the following formula of treatment liquid: 1-2 g/L of refining agent, 1-2 g/L of refining emulsifier and the balance of water.
The refining treatment in the step I is carried out at the temperature of 80-98 ℃ for 15-30 min.
In the second step, the temperature of acid neutralization is 20-40 ℃, and the time is 10-20 min.
The formula of the dye solution adopted in the dyeing in the third step is as follows: 0.5-2 g/L of leveling agent, 0.5-1.5 g/L of glacial acetic acid, 0.01-6% of acid dye and the balance of water.
The specific dyeing method in the third step is as follows: firstly adding a leveling agent for running for 5-10 min, then using 1/2 glacial acetic acid and an acid dye to dissolve and stir uniformly, slowly adding into a dye vat, controlling the feeding time to be 20-30 min, then using the residual glacial acetic acid to adjust the pH value of a dye solution to be 4-6, finally controlling the heating rate, heating to 98 ℃, and keeping the temperature for 30-40 min.
And in the third step, the acid color fixing temperature is 75-85 ℃, and the time is 15-30 min.
In the third step, the dosage of the acidic color fixing agent is 2-5 g/L.
The softening treatment in the step IV is carried out at the temperature of 20-40 ℃ for 15-30 min.
In the fourth step, the softening treatment adopts a hydrophilic softening agent, and the dosage is 1-3 g/L.
The invention has the following positive effects:
(1) a large number of experiments show that the DM-2537 acidic color fixing agent can realize direct color fixing without discharging liquid after dyeing and still can obtain a good color fixing effect on nylon high-elastic fabrics, and particularly, various color fastness of dark colors/bright color systems such as black, bright red, turquoise blue and the like is even superior to that of the traditional process, so that the process can be shortened, and the water consumption can be reduced.
(2) Compared with the traditional process, the short-flow dyeing method disclosed by the invention can save time by 1-2 h (the time saving rate is 12.5-25%), can save water by at least 2 cylinders (the water saving rate is at least 28.6%) in the whole dyeing process, and has obvious energy-saving and emission-reducing effects.
