Environment-friendly composite disperse dye composition capable of performing discharge printing

Abstract

The invention discloses an environment-friendly composite disperse dye composition capable of performing discharge printing. The composition comprises the following components in percentage by weight: 40 to 85 percent of component A, 5 to 10 percent of component B, 10 to 50 percent of component C, 0 to 40 percent of component D and 0 to 10 percent of component E, wherein the component A is a compound shown in a formula (1); the component B is one or more of compounds shown in the formula (2); the component C is a compound shown in the formula (3); the component D is a compound shown in the formula (4); and the component E is one or more of compounds shown in the formula (5). The environment-friendly composite disperse dye composition capable of performing discharge printing can be used for direct printing, discharge printing and resist printing, has superior fastness and has the advantages of superior environmental friendliness, superior discharge printing property and high fastness in other aspects.

Description

technical field [0001] The invention relates to a disperse dye composition, in particular to an environment-friendly composite disperse dye composition capable of dyeing and printing. Background technique [0002] With the continuous improvement of energy saving and environmental protection requirements, the printing industry is monopolized by its less water consumption, less pollution, and fast production cycle. Discharge printing is only a small branch of the printing industry. Although it is more difficult to process than direct printing, it has printing advantages that cannot be replaced by direct printing. The biggest feature of discharge printing is that it can print light-colored patterns on dark-colored fabrics. Although there are many discharge dyes on the market, especially black discharge dyes, such as the black discharge dyes reported in the literature of CN100528974C as the patent number, although its white discharge effect is good, it contains the disperse dye...
