Embodiment 1

[0054] 21 grams of dyes represented by the general formula I-A, 25 grams of dyes represented by the general formula I-C and 60 grams of dispersant MF are mixed with water, and then ground and dispersed with a grinder until the particle size of the disperse dye is 1-3 μm. Stop grinding, and then spray-dry at high temperature to obtain red dye powder (disperse dye composition).

Embodiment 2

[0056] Mix 15 grams of dye with the general formula I-C, 75 grams of the dye with the general formula II-A and 80 grams of dispersant MF, add water and mix them, grind and disperse with a grinder until the particle size of the disperse dye is 1-3 μm , stop grinding. The blue dye powder (disperse dye composition) was obtained by spray drying at high temperature.

Embodiment 3

[0058] 75 grams of the dyestuff represented by the general formula II-B, 10 grams of the dyestuff represented by the general formula III-C and 120 grams of dispersant MF are mixed with water, and then ground and dispersed with a grinder until the particle size of the disperse dye is 1 When -3μm, stop grinding. The blue dye powder (disperse dye composition) was obtained by spray drying at high temperature.

Abstract

The invention discloses a disperse dye composite, which consists of the original dye and an aid, wherein the original dye consists of 2 to 4 kinds selected from 0 to 2 kinds of dyes shown as a general formula (I), 0 to 2 kinds of dyes shown as a general formula (II) and 0 to 2 kinds of dyes shown as a general formula (III), wherein in the general formula (I), R1 and R3 is hydrogen or chlorine independently, R2 is chlorine or nitryl, R4 is hydrogen, methyl, ethyl or methoxyl, and R5 is hydrogen, nitryl or methyl; in the general formula (II), R6 is methyl, ethyl or methoxyl, and R7 is hydrogen, nitryl or methyl; and in the general formula (III), R8 is chlorine or nitryl, R9 is hydrogen or chlorine, and R10 is hydrogen, nitryl or methyl. The disperse dye composite has the advantages of high dispersity and oxidative resistance, and is suitable for processing technologies of pretreatment and one-bath dyeing of polyester fabrics in the presence of an oxidant; and the polyester fabrics dyed by the disperse dye composite are gorgeous in color and high in soaping fastness, dry friction fastness and wet friction fastness.

Description

technical field [0001] The invention belongs to the field of fine chemicals, and in particular relates to a disperse dye composition used for pretreatment and dyeing in one bath, a dyeing method and a preparation method thereof. Background technique [0002] At present, with the higher and higher requirements for energy saving, energy saving and emission reduction in printing and dyeing processing, it is of great significance to develop dyeing processing technology suitable for polyester short process. [0003] According to the artificial impurities added by polyester fiber weaving, there are mainly two types, one is impurities such as size and surfactant on polyester woven fabrics, and the size is mostly polyvinyl alcohol (PVA pulp), polyacrylic acid and esters (PA slurry), or a mixture of polyvinyl alcohol and polyacrylic acid and esters. The other is impurities such as oils and surfactants on polyester knitted fabrics, most of which are complexes of spinning oils and ant...
