Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and relates to a washing-free reactive dye non-aqueous solvent dyeing device and a dyeing method thereof. Background technique [0002] At present, reactive dyes are mostly used in the dyeing of reactive loose fibers, yarns, fabrics or garments. During the dyeing process, due to the hydrolysis of active groups in aqueous media, not only a large amount of reactive dyes are wasted, but also in the dyeing process. Consuming a large amount of water and discharging a large amount of high-color sewage that is difficult to treat are also the bottlenecks that have always existed for reactive dyes. [0003] In order to avoid the hydrolysis reaction of reactive dyes and improve the utilization rate of reactive dyes, scientists have paid attention to and studied the dyeing of reactive dyes in non-aqueous media very early. The advantage of dyeing with non-aqueous media is that reactive ...
