Abstract

The invention relates to a room temperature wool pad dyeing microwave color fixing method which comprises the following steps: (1) mixing active dye or acid medium-contained dye for wool, cosolvent, areducing agent, a level dyeing agent and a penetrating agent at room temperature and uniformly stirring; (2) padding wool fabrics in the dye liquor, wherein the padding residual rate is 80-120 percent; and carrying out heating color fixation processing, water washing and drying on the wool by a microwave. The invention has simple process, low cost, high productivity, short period, energy saving and environmental protection and is suitable for industrialized production; the level-dyeing performance of dyeing and the planeness of the fabrics are better than those of a common dyeing method, andthe dosage of dyeing auxiliary agents is greatly reduced.

Description

technical field [0001] The invention belongs to the field of wool pad dyeing, in particular to a microwave color fixing method for wool pad dyeing at room temperature. Background technique [0002] Wool fiber has many excellent properties and is deeply loved by consumers. However, due to the hydrophobic outer skin layer and dense scale layer on wool fiber, the dyeing and internal diffusion of dyes are hindered. Therefore, wool dyeing is generally carried out in the Boiling or near boiling aqueous solution. This not only adversely affects the quality of the wool fiber, but also affects the spinnability, yield, hand feel, vividness and luster, and high temperature and long-term boiling also consumes a lot of energy. Water-saving and energy-saving dyeing of wool has been paid more and more attention by the wool spinning industry. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a microwave color-fixing method for w...
