Abstract

The invention relates to a water-free reactive dye printing treatment liquid, which is composed of the following components in mass fractions based on the total weight: water-based crosslinking agent: 1%-15%, water-based polyester emulsion: 20%-70% %, the balance is water. The invention also discloses the application of the above water-free reactive dye printing treatment solution in transfer printing of fabrics. The water-free reactive dye printing treatment liquid of the present invention can enhance the cross-linking fixation degree of the dye and the fiber, and at the same time, the fabric treated with the treatment liquid will not affect the fabric feel after printing, and the utilization rate of the dye in the transfer printing process is improved. The discharge of printing and dyeing wastewater in actual production is reduced.

Description

technical field [0001] The invention relates to the technical field of transfer printing, in particular to a water-free reactive dye printing treatment liquid and an application thereof. Background technique [0002] Fabrics transferred with reactive dyes have more floating colors and poor color fastness before washing; after washing, the color fastness is improved but a large amount of printing and dyeing wastewater will be generated. Therefore, it is of great significance to invent a method for washing-free reactive dye printing, so as to improve the utilization rate of dyestuffs and reduce the discharge of printing and dyeing wastewater during the transfer printing process of fabrics. [0003] CN03819480.5 discloses a method for dyeing or printing cellulose-containing fiber materials using disperse dyes, which includes bonding with water-soluble or water-dispersible polyester resin and water-soluble or water-dispersible acrylate Aqueous composition of agent for treating ...
