Problems solved by technology
[0004] With the functional and diversified development of textile materials, various blended fabrics such as polyester-nylon interwoven, polyester-nylon composite fibers, polyester-cotton, polyester-viscose and other clothing fabrics have become popular in recent years. The traditional dyeing and finishing process is long, energy-consuming and water-consuming. Disadvantages such as high pollution discharge and high cost restrict the style and quality of multi-fiber blended fabrics
The one-bath two-step process can greatly shorten the dyeing time and reduce sewage discharge. Currently, the reactive dyes dyed by the one-bath two-step method on the market still have problems such as low color fixation rate, poor reproducibility, and poor color fastness. The two-step dyeing method cannot be widely applied

The invention discloses a reactive blue to black dye composition, a dye product and applications thereof. The reactive dye composition comprises component A, component B and component C, and the component A is selected from at least one compound shown in formula (I), and the component B is selected from at least one formula ( The compound shown in II), the component C is selected from at least one compound shown in formula (III). The reactive dye product includes the reactive dye composition, which can be sold as a commodity or directly applied to printing and dyeing of textile materials. The invention also provides the application of the reactive dye product in the printing and dyeing of cellulose fiber, polyamide fiber or its blended fabrics. When printing and dyeing fabrics, it has blue to black hue, high color fixing rate, good reproducibility, and various color fastnesses. Excellent fastness, especially rubbing resistance and washing fastness, good high temperature printing and dyeing performance, especially suitable for one-bath two-step dyeing of cotton blended fabrics.
