Embodiment 1

[0027] 17.6 grams of formula (I) compound, 9.4 grams of formula (II) compound, 11 grams of formula (III) compound and 62 grams of sodium lignosulfonate and 300 grams of water were ground and dried together to prepare a composite disperse dye.

Embodiment 2

[0036] 17.6 grams of formula (I) compound, 9.4 grams of formula (II) compound, 11 grams of formula (III) compound and 62 grams of sodium lignosulfonate and 300 grams of water were ground and dried together to prepare a composite disperse dye.

Embodiment 3-13

[0046] According to the components and contents shown in Table 3, the prepared composite dye composition, the auxiliary agent was mixed with water, ground, and spray-dried to obtain a composite disperse dye.

[0047] table 3

[0048]

[0049] In Table 3, the structural formula of the compound of formula (V) is as follows:

[0050]

[0051] From the above comparison, it can be seen that the composite disperse dye of the present invention with specific components does not contain the compound of formula (IV), the lifting power and strength are improved, and the cost is reduced.

[0052] According to the method identical with embodiment 1,2, obtain black textile material.

[0053] According to the standards of GB / T2397-2003 and GB / T2394-2006, the lifting force and strength were tested, and the results are shown in Table 4.

Abstract

The invention relates to a composite dye composition, composite disperse dye and a preparation method thereof. The composite dye composition is composed of a formula (I), a formula (II), a formula (III) and an optional formula (IV). The composite disperse dye prepared from the composite dye composition has high intensity and lifting force, and is suitable for 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. The composite disperse dye is suitable for dyeing and printing 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 of not being good enough in various properties, especially in aspects such as lifting power and strength, 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, component B, component C and optional component D, wherein, component A is following formula (I) compound, [0004] [0005] Component ...
