Description
Technical Field
The utility model belongs to the technical field of the dyeing and finishing of weaving, a washing-free non-aqueous solvent dyeing equipment of reactive dyes is related to.
Background
Most of the existing reactive dyes for dyeing loose fibers, yarns, fabrics or ready-made clothes are reactive dyes, and the hydrolysis of reactive groups in an aqueous medium in the dyeing process not only causes the waste of a large amount of reactive dyes, but also consumes a large amount of water and discharges a large amount of high-chroma sewage which is difficult to treat in the dyeing process, which is a bottleneck of the reactive dyes all the time.
In order to avoid hydrolysis of reactive dyes and to increase the availability of reactive dyes, scientists have long noted and studied the dyeing of reactive dyes in non-aqueous media. The non-aqueous medium dyeing has the advantages that the reactive dye is not hydrolyzed in the dyeing process, and the reaction degree of the reactive dye with loose fibers, yarns, fabrics or ready-made clothes can be improved. However, there are still many problems in dyeing with non-aqueous media, mainly including the solubility of reactive dyes in non-aqueous media, the swelling capacity of loose fibers, yarns, fabrics or garments in non-aqueous media, the solubility of fixing alkaline agents in non-aqueous media, and the leveling property and permeability of dyeing. Although the reactive dye has a plurality of difficulties in dyeing in the non-aqueous medium, the cost of water is gradually increased at the present stage, people pay more and more attention to environmental protection, and the non-aqueous medium dyeing of the reactive dye also receives more and more attention with good application prospect.
In the last 80 th century India textile technology research institute, dimethylformamide is adopted to dissolve reactive dye C.I. reactive red 12, trichloroethylene is added in batches in the process of heating to 80 ℃, and heat preservation is carried out for 1h, so that the dye is almost completely dyed, and the color fixing rate is 84%. Although the method provides a better solvent dyeing idea, the color fixing rate has less advantages than the traditional dyeing method, a large amount of water is still needed for high-temperature soaping to remove the loose color after dyeing, the industrial application prospect is not large, and further development is not achieved.
The solvent reverse micelle dyeing method is a novel non-aqueous solvent dyeing process appearing in recent years, the research on the non-aqueous solvent dyeing of the reactive dye is greatly advanced recently, and the Guangdong Yida textile company develops a washing-free non-aqueous solvent dyeing method for the reactive dye, the method can ensure that the reactive dye is completely and uniformly dyed and fixed on cotton fibers, and the washing and neutralization are not needed after the dyeing is finished, so the dyeing period is short, and the energy consumption is low.
