Embodiment 1

[0066] 5 grams of yellow dye represented by general formula (I-A), 50 grams of yellow dye represented by general formula (I-C) and 82 grams of dispersant MF are mixed with water, and then ground and dispersed with a grinder until the particle size of disperse dye is When it is 1-3μm, stop grinding. Then, the yellow dye powder (disperse dye composition) was obtained by high-temperature spray drying.

Embodiment 2

[0068] 15 grams of yellow dye represented by general formula (I-B), 45 grams of yellow dye represented by general formula (I-E) and 120 grams of dispersant MF are mixed with water, and then ground and dispersed with a grinder until the particle size of disperse dye is When it is 1-3μm, stop grinding. Then, the yellow dye powder (disperse dye composition) was obtained by high-temperature spray drying.

Embodiment 3

[0070] 55 grams of yellow dye represented by general formula (I-E), 8 grams of orange dye represented by general formula (II-A) and 130 grams of dispersant MF are mixed with water and then ground and dispersed with a grinder until the disperse dye When the particle size is 1-3 μm, stop grinding. Then, the yellow dye powder (disperse dye composition) was obtained by high-temperature spray drying.

Abstract

The invention discloses a disperse dye composition, which consists of an original dye and an aid, wherein the original dye consists of any 2-4 kinds of dyes selected from 0-2 kinds of dyes shown as a general formula (I), 0-2 kinds of dyes shown as a general formula (II), 0-2 kinds of dyes shown as a general formula (III) and 0-2 kinds of dyes shown as a general formula (IV), wherein R1, R4, R6 and R8 in the formula (I), formula (II), formula (III) and formula (IV) are independently hydrogen, methyl or methoxy; when R2 is hydrogen, R3 is 2-nitrobenzophenone or 2,4-dinitrophenyl; when R2 is methyl, ethide or cyanoethyl, R3 is benzyl or 2-methyl benzyl; R5 and R7 are independently hydrogen, nitryl, methyl or ethyl; and R9 is methyl, ethyl, benzyl, 2-methyl benzyl or 2-nitrobenzophenone. The invention further discloses a dyeing method for a dacron. The disperse dye composition provided by the invention has the advantages of high dispersing property and high oxygen resistance.

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...
