Abstract

The invention relates to washing-free reactive dye printing treatment liquid. By using the total weight as the standard, the washing-free reactive dye printing treatment liquid is prepared from the following ingredients in percentage by mass: 1 percent to 15 percent of a water-based crosslinking agent, 20 percent to 70 percent of water-based polyester emulsion and the balance water. The inventionalso discloses application of the washing-free reactive dye printing treatment liquid to transfer printing on fabrics. The washing-free reactive dye printing treatment liquid provided by the inventionhas the advantages that the crosslinking fastness of dye and fiber can be enhanced; meanwhile, after the fabric treated by the treatment liquid is printed, the hand feeling of the fabric cannot be influenced; the dye utilization rate in the transfer printing process is improved; and the discharge of printing and drying waste water in practical 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 ...
