A kind of disperse dye mixture and its application

Abstract

The invention discloses a disperse dye mixture and an application thereof. The disperse dye mixture is a dark blue to black dye mixture, comprising dye A, dye B, dye C and its auxiliaries, wherein the weight percentage of dye A in the mixture is: 10% to 60%, the weight percentage of dye B is 1% to 10%, the weight percentage of dye C is 2% to 40%, and the rest are auxiliary agents. The dye mixture prepared by the invention is applied to the dyeing and printing of hydrophobic fiber materials, and has excellent improvement in both dyeing and printing, better jet blackness, and higher washing fastness and sublimation fastness.

Description

technical field [0001] The invention relates to the technical field of disperse dyes, and more particularly to a disperse dye mixture and its application. Background technique [0002] In recent years, with the continuous development and expansion of China's dye industry, dye varieties have also been transformed and upgraded in the direction of high color fastness, high improvement, and high added value to meet the needs of the market. Among them, disperse dyes with high improvement and high color fastness have become the focus of market attention. The market has higher and higher requirements for dyes, especially disperse black, and higher requirements for color fastness of textiles. [0003] At the same time, due to the increasing pressure on environmental protection in recent years, the production cost of dyes has increased, the price of dyes has risen more, and the cost of dyeing and chemical materials for printing and dyeing enterprises has greatly increased. Therefore...

Problems solved by technology

Conventional disperse dark blue and disperse black, such as disperse blue ECO, disperse black ECT, and disperse black S-4BL, although the price is relatively low, but the improvement is average, and the color fastness cannot meet the requirements

[0004] In recent years, domestic and foreign dyestuff manufacturers have successively launched a series of high-fastness dyes, such as the WW series launched by Huntsman with a phthalimide structure, and the XF2 series launched by DyStar with a long carbon chain ester group. Structure; Chinese patents CN201610283333.9 and CN201510988025.1 also provide some high-fastness dye varieties, but the biggest disadvantages of the above-mentioned dye varieties are complex structure, high production cost, and general improvement.
