The invention discloses a reactive dark blue dye composition. The dye composition comprises a component A, a component B and a component C, the component A is selected from at least one compound represented by formula (I), the component B is selected from at least one compound represented by formula (II), and the component C is selected from at least one compound represented by formula (III). Thedye composition and a dye product have the advantages of high fixation rate, good reproducibility, excellent color fastness, especially outstanding light fastness and washing fastness, and suitableness for printing and dyeing of cellulose fibers or cellulose-containing fiber materials.
Description
[0001] (1) Technical field [0002] The invention relates to a reactive navy blue dye composition, a dye product and its application in printing and dyeing of cellulose fibers or materials containing cellulose fibers. [0003] (2) Background technology [0004] Nylon belongs to polyamide fiber, which has high resilience, fatigue resistance, and good moisture absorption performance; while cotton belongs to cellulose fiber, which has the advantages of soft hand feeling, good air permeability and moisture absorption, and comfortable wearing, but it is easy to wrinkle. After weaving brocade and cotton, the fabric can not only have the advantages of brocade and cotton fibers, but also overcome their respective shortcomings, showing a strong body and smooth feel. Affected by the structure of polyamide and cellulose itself and the performance and process of the dyes used in the dyeing process, the traditional nylon / cotton fabric dyeing method uses two-bath dyeing methods such as dispe...
