Problems solved by technology

[0002] Reactive dark dyes such as brown, blue, navy blue and black dyes have become the most used varieties in reactive dyes, but the existing dark dyes still have low dyeing rate and fixation rate, and the dyeing depth is not strong. The color fastness is not good, dyed fabrics are not easy to clean, etc. In recent years, dye researchers have done a lot of work in the research and development of reactive dark dyes, such as patents CN102245712A, CN1730566A, CN1745147A, etc., but with the improvement of ecological environmental protection requirements and The development of textile fabrics has put forward higher requirements for products, and the existing dark dyes still need to be further improved

Abstract

The invention discloses a dark reactive dye composition and a dye product. The composition is prepared from the following components in percentage by mass: 10-90 percent of a component A, 5-85 percentof a component B and 5-30 percent of a component C, based on total mass of the components A, B and C, wherein the component A is selected from at least one dye compound as shown in a formula (I), thecomponent B is selected from at least one dye compound as shown in a formula (II), the component C is selected from at least one dye compound as shown in a formula (III). A dark reactive dye productcontains the dark reactive dye composition. The dark reactive dye composition and the dye product have good solubility, are easy to wash, cannot be easily stained during washing, and have the characteristics of excellent compatibility, good dyeing depth, excellent fixation rate and excellent fastness.
