Abstract

The invention relates to a micro-water dyeing method suitable for wool. The micro-water dyeing method comprises the following steps that a, products to be dyed are prepared; b, a dedicated dyeing system is configured, specifically, reactive dyes and metered water only used for dissolving the reactive dyes are uniformly stirred, and poor solvents of the reactive dyes are added to prepare the dedicated dyeing system; c, dyeing is carried out; d, soaping is carried out; e, dehydrating is carried out; and f, drying is carried out, and dyeing products are obtained. Compared with a traditional woolreactive dyeing method, the dyeing method does not require any accelerating salt, with the help of non-aqueous media with low surface tension, the reactive dyes can be rapidly dyed to the surfaces ofwool fibers, the reactive dyes hardly hydrolyze without an alkaline agent, and the fixation rate of the reactive dyes is greatly improved. According to the micro-water dyeing method suitable for the wool, the use ratio of the reactive dyes for wool dyeing is effectively improved, the dyed wool is not required to be specifically processed, and the wet rubbing fastness meets the requirements in themarket.

Description

technical field [0001] The invention relates to a dyeing method, in particular to a micro-water dyeing method suitable for wool, and belongs to the technical field of dyeing. Background technique [0002] In recent years, the application of wool-specific reactive dyes has become more and more common. However, because wool structure is one of the most complex natural fibers, the surface is covered with scales and is hydrophobic. The dye solution is not easy to diffuse into the fiber, which hinders the adsorption and diffusion of dyes. , the dye is difficult to dye to the fiber. Especially for some dyes with low affinity, the dye concentration in the raffinate is relatively high, and the sewage treatment is difficult. Therefore, wool dyeing generally adopts higher temperature and longer dyeing time, resulting in higher energy consumption during dyeing and greater damage to fibers, especially when dyeing outside the isoelectric point of wool, the damage to wool is greater. Ro...
