Abstract

The invention provides an ultraviolet light water-free washing method of a denim fabric made of pigment dyeing yarns. The water-free washing method is characterized by comprising the following process flows of: (1) providing denim clothes made of the pigment dyeing yarns; (2) conducting pretreatment such as washing treatment, softening treatment and modified TiO2 treatment on the denim clothes made of the pigment dyeing yarns; (3) placing special parts or a whole set of the denim clothes to be washed under an ultraviolet lamp for irradiation; and (4) conducting aftertreatment such as washing and drying on the denim clothes after irradiation. Compared with a traditional denim fabric washing method, the water-free washing method has the advantages of short flow, wide color spectrum, firmness in dying, high dye uptaking rate, low cost, less energy consumption and water saving, capability of basically achieving zero emission, and the like. Compared with coating, the water-free washing method has the advantages of good flexibility, excellent air permeability, good weather fastness, resistance to sunlight, resistance to washing, and the like, and effectively solves the problems of pollution, denim shrink after washing, and the like in a washing industry. In addition, the water-free washing method also has the advantages of capabilities of saving water to 100% and regularly washing.

Description

technical field [0001] The invention relates to the field of dyeing and post-finishing of textiles, in particular to a water washing method for weaving denim fabrics with paint dyed yarns. Background technique [0002] Paint-dyed denim fabrics are not coated fabrics, but use paint to dye the yarn directly, rely on the film-forming substances formed by binders and cross-linking agents to fix the pigment on the yarn, and then use the paint yarn as a warp to weave into denim clothing. Compared with dye dyeing, it has the advantages of short process, wide chromatogram, firm dyeing, high dyeing rate, low cost, low energy consumption, water saving, and basically zero discharge. It has the advantages of good air permeability, good weather resistance, sunlight resistance and washing resistance. [0003] The basic principle of paint dyeing is mainly to use film-forming substances to coat the pigment on the surface of the yarn. If this layer of film is damaged, the pigment will co...
