Abstract

The invention discloses a disperse dye with high washing fastness and a preparation process thereof. According to the key point of the technical scheme, the dye is prepared from the following components in parts by mass: 50 to 60 parts of C.I. Direct yellow 106 dye, 30 to 40 parts of plant extract, 50 to 60 parts of o-phenylphenol, 20 to 30 parts of methyl salicylate, 30 to 40 parts of hematoxylin, 4 to 8 parts of dibenzodioxazine, 3 to 8 parts of cyanuric chloride, 5 to 10 parts of anti-deposition agent, 4 to 8 parts of dispersant, 3 to 8 parts of surfactant, 5 to 6 parts of stabilizer and 7 to 10 parts of bacteriostatic agent. The disperse dye with high washing fastness is not easy to decolor and oxidize during use, and has excellent washing fastness; the preparation process of the disperse dye with high washing fastness is simple in steps, the vegetable red dye is adopted as one of main components, the yellow color is natural, the cost is low, and the disperse dye has a wide application prospect.

Description

technical field [0001] The invention relates to the field of dyes, in particular to a disperse dye with high washing fastness and a preparation process thereof. Background technique [0002] With the continuous improvement of living standards, consumers have higher and higher requirements for textiles, and the demand for various dyes is also increasing. However, some textiles often suffer from decolorization due to the poor performance of the dyes used.
