Embodiment 1

[0099] 10.7 grams of dye A with general formula (Ie), 31.2 grams of dye B with general formula (IIe) and 20.0 grams of dye C with general formula (IIIi) and 4.7 grams of dye D with general formula (IVc) and 13.4 gram of dye E with the general formula (Ve) was ground together in a sand mill for 3 hours with 500 milliliters of water and 20 grams of sodium lignosulfonate, and then spray-dried (inlet temperature 130°C, outlet temperature 60°C), namely Disperse dye mixture 1 was obtained.

Embodiment 2

[0101] 3.6 grams of dye A containing general formula (Id) and 0.5 gram of diffusing agent MF and 10 g of water, 12 grams of dye B containing general formula (IId) and 1 gram of diffusing agent MF and 40 g of water, containing general formula (Ⅲj) 5.1 grams of dye B and 1 gram of dispersing agent MF and 20 g of water, 8.6 grams of dye D containing general formula (IVe) and 0.5 gram of dispersing agent MF and 30 g of water, 4.6 grams of dye E containing general formula (Ⅴf) and Mix 0.5 g of diffusing agent MF and 30 g of water, grind and spray dry, and finally mix four kinds of dyes to obtain disperse dye mixture 2.

Embodiment 3

[0103] Contain 5.1 grams of commercial dye A of general formula (Ib), contain 14.8 grams of commercial dye B of general formula (IIa), contain 8.9 grams of commercial dye C of general formula (IIIk), and contain 9.8 grams of commercial product of general formula (IVi).

Abstract

The invention relates to the technical field of dye, and provides a disperse dye mixture and application thereof, aiming to solve the problems that the wash resistance and crockfastness resistance of an ordinary sunshine disperse dye cannot be ensured at the same time. The disperse dye mixture is prepared by mixing a dye A, a dye B, a dye C, a dye D and a dye E. By adopting the dye mixture for dyeing, wash resistance and crockfastness resistance are satisfactory.

Description

technical field [0001] The invention relates to the technical field of dyes, in particular to a compound mixture of black disperse dyes and its application. Background technique [0002] As we all know, neither anthraquinone type disperse dyes, azo type dyes nor heterocyclic type disperse dyes can simultaneously satisfy excellent light fastness, washing and rubbing fastness. However, with the improvement of people's quality of life and the needs of national construction, based on the market's growing demand for high-end sportswear, casual wear, mountaineering suits, military camouflage fabrics, and automotive interior fabrics, a disperse dye is required to meet its needs. Requirements for high light fastness and high rubbing fastness. For this reason, it is urgent to develop a kind of sun-resistant, rub-resistant disperse dyes. [0003] The Chinese patent application number 200710066619.2 discloses a disperse black dye composition, which provides a disperse black dye compo...
