Abstract

The invention discloses a bright yellow reactive dye mixture and an application thereof. The bright yellow reactive dye mixture is prepared by mixing the following dyes in parts by weight: 70 to 80 parts of dye I, 10 to 15 parts of dye II and 10 to 15 parts of dye III; the dye I is a compound and a salt of the compound in formula I; the dye II is a compound and a salt of the compound in formula II; the dye III is a compound and a salt of the compound in formula III; the formula I, the formula II and the formula III are respectively shown in the attached figures. The bright yellow reactive dye mixture has the advantage that a fabric which is printed and dyed by the dye mixture has good sun exposure-resistant, sweat-resistant and abrasion-resistant properties.

Description

technical field [0001] The invention belongs to the field of dyes, in particular, the invention relates to a bright yellow reactive dye mixture and its application. Background technique [0002] Recently, the application practice of reactive dyes has put forward higher requirements on the dyeing quality and the economy of the dyeing method. In addition, textiles used outdoors, such as sportswear, military or police training clothing, need to have good light fastness, rubbing fastness and perspiration fastness, and the current reactive dyes often cannot meet their needs. [0003] Therefore, there is an urgent need in the market to develop a dye with excellent sun resistance, perspiration resistance, and friction resistance, especially for dyes that require excellent fastness properties for printed and dyed fabrics. This dye can be used for hydroxyl or nitrogen-containing fibers. Dyeing and printing of materials can also be used in inkjet printing for printing hydroxyl-contai...
