Title:
REACTIVE DYE MOISTURE FIXATION CONTINUOUS DYEING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/088242
Kind Code:
A1
Abstract:
A reactive dye moisture fixation continuous dyeing method, comprising steps of pretreatment, dye liquor padding, pre-drying, rolling and stacking. Compared with a conventional pad-drying pad-steaming process, processes of reactive material steam, solid, liquid padding and steaming are removed during operation, the process is short, the operation is simple, and the working efficiency is improved; the use amount of inorganic salt is low, reactive dye low-salt dyeing is achieved, and environmental pollution is reduced. Compared with a cold pad-batch process, in this method, a color sample is pre-dried after being padded by a dye working liquor, the moisture content is controlled within a certain range, hydrolysis of the dye is reduced, and the fixation rate is increased. The fabric obtained by using the method is full in cloth cover and deep in color yield, and the color fastness comprehensively satisfies the standard requirements.
