Abstract

The invention relates to a composite dye composition, composite disperse dye and a preparation method thereof. The composite dye composition is composed of compounds as shown in a formula (I-a), a formula (I-b), a formula (II) and a formula (III). The composite disperse dye prepared from the composite dye composition has good comprehensive fastness property and high lifting force, and is suitablefor dyeing and printing terylene and blend fabrics.

Description

technical field [0001] The invention relates to an environment-friendly composite dye composition, a composite disperse dye, and a preparation method thereof, which are suitable for dyeing and printing of polyester and its blended fabrics. Background technique [0002] Composite disperse dyes are dyes made by compounding different dye compounds. There are already many composite disperse dyes. Compared with single dyes, composite disperse dyes have obvious advantages in both cost and performance. However, the existing composite disperse dyes still have the problem that various properties are not good enough, especially in the comprehensive properties such as comprehensive fastness performance and lifting power, which still need to be improved. Contents of the invention [0003] The invention provides a kind of compound dye composition, is made up of component (A), (B), (C), and wherein component (A) is the mixture of following formula (I-a) compound and (I-b) compound, ...
