Efficient and continuous dyeing process method for textile fabric through wet-state steaming

Abstract

The invention provides an efficient and continuous dyeing process method for textile fabric through wet-state steaming, which belongs to the fabric dyeing method. The process method comprises the following steps in sequence: fabric soaking in dyeing solution, bake-steaming for color fixation, water washing and drying and feeding. During the drying and feeding procedure, the humidity of mixed gas in the reaction steam box is 25-35 percent, the temperature of the mixed gas is 120-130 DEG C, the air volume of the mixed gas is 4m3 / s, and the processing time is 2-3 minutes; the saturated vapor pressure is 0.15-0.2MPa; and during the water washing procedure, the content of the water softener B in lotion is 2-3g / L, and the rest is water. The dyeing process method shortens the process flow, thereby not only improving the production efficiency, but also saving the energy. In addition, compared with the traditional dyeing process, the dyeing process method has the advantages of high color fixing speed, high color fixing rate, bright color, no dye transfer, low alkali consumption, good reproducibility, good levelness, good penetration and the like. Therefore, the invention can be used for obtaining good washing-resistant and friction-resistant fastness.

Description

technical field

[0001] The invention provides a fabric dyeing method, in particular a high-efficiency continuous dyeing process for home textile fabrics made of natural cellulose fibers such as cotton and hemp and regenerated cellulose fibers (such as rayon, Lyocell, and Modal). Background technique

[0002] With the implementation of national energy saving and emission reduction and cleaner production policies and regulations, the printing and dyeing industry is also actively developing new dyeing and finishing processes that are conducive to energy saving, emission reduction and cleaner production. Among them, dyeing technology is one of the key areas of development. First of all, develop new varieties of environmentally friendly and efficient reactive dyes to gradually replace those dyes with low dyeing rate, low color fixation rate and high environmental pollution pressure, such as sulfur dyes, direct dyes, azo dyes, acid dyes, etc. Second, improve the dyeing process. ...
