Abstract

Disclosed in the present invention is a dispersed dark blue dye preparation method, comprising the following steps: 1) mixing dye monomers or finished dye with an auxiliary agent, the mixed dye after mixing comprising dye monomer A as shown in formula (I) having a mass fraction of 0.1-70%, dye monomer C as shown in formula (III) having a mass fraction of 0.1-15%, and the remaining mass being the auxiliary agent; in formula (I), R＝CH3 or CH2CH3; and in formula (III), R1＝CL or Br and R2＝COCH3 or OCOCH3; 2) adding an appropriate amount of water to grind until the dispersion is uniform; and 3) spray-drying. The dye prepared using the present method has the advantages of a high dyeing rate, good washing fastness, excellent fastness, low thermal migration resistance, high strength, and relatively low price.

Description

technical field [0001] The invention belongs to the technical field of disperse dyes, in particular to a preparation method and application of disperse dark blue dyes. Background technique [0002] In the quality inspection of textile color fastness, color fastness to washing is an important inspection item, and its test results are directly related to the overall color fastness of the fabric. Some dyes with poor color fastness can also cause varying degrees of damage to the human body and pollute the environment. Therefore, different organizations and countries have formulated corresponding standards to strictly limit the color fastness grades of clothing and home textiles. [0003] Judging from the current situation of textile fabrics, the proportion of fabrics made of a variety of fibers is increasing year by year, such as some domestic high-end fabrics, including polyester blended fabrics. The dark blue monomer dyes currently available on the market are expensive and ca...
