Abstract

The invention relates to a vintage dyeing method for knitted wool fabric. The method comprises the steps of: (1) laying knitted wool fabric fully deoiled in a dyeing machine, feeding water, adding a pretreating agent, conducting temperature rise and preservation, discharging pretreatment solution, and washing; (2) feeding water, adding in a cation modifying agent and glacial acetic acid, controlling the pH value at 5-7.5, conducting temperature rise and preservation, discharging residual liquid, and washing; and (3) feeding water, adding in a leveling agent at room temperature, running for 5 to 10min, adding in coating, running for 10-20min, then conducting temperature rise, adding in a color fixing agent and a softening agent, running for 10-20min, then conducting temperature rise, adding in glacial acetic acid, running for 30-60min, conducting temperature reduction to 55-60 DEG C, discharging liquid and washing. The method is adopted for dyeing the wool fabric, the dye-uptake of the coating is high, no residual liquid is left; the excellent washing fastness and wet friction color fastness are achieved, and good application prospects can be reached.

Description

technical field [0001] The invention belongs to the field of fabric dyeing, in particular to an imitation dyeing method for knitted wool fabrics. Background technique [0002] Coatings have long been widely used in fabric printing in the printing and dyeing industry. It was not until the 1960s that some patents and research reports on paint dyeing began to be published, but due to the unsatisfactory dyeing effect, this technology has not been widely used. Since the 1990s, with the continuous emergence of new adhesives and additives and the continuous improvement of application technology, paint dyeing technology has received widespread attention and promotion at home and abroad, especially for dyeing light and medium-color products. In recent years, paint-dyed products such as colored denim, knitted denim, distressed garments, washed cloth and other fabrics have been favored by many consumers because of their rich colors and unique styles. [0003] Compared with dye dyeing...
