Embodiment 1

[0059] 2 grams of dye of general formula (I-A) (red), 20 grams of dye of general formula (II-A) (blue), 5 grams of dye of general formula (III-A) (orange) And 73 grams of dispersant MF, after adding water and blending, grind and disperse with a grinder until the particle size of the disperse dye is 1-3 μm, stop grinding. The navy blue dye powder (disperse dye composition) was obtained through high-temperature spray drying.

Embodiment 2

[0061] 2 grams of dye of general formula (I-B) (red), 45 grams of dye of general formula (II-B) (blue), 3 grams of dye of general formula (III-B) (orange) And 50 grams of dispersant MF, after adding water and blending, 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

[0063] 5 grams of dye of general formula (I-C) (red), 15 grams of dye of general formula (II-C) (blue), 20 grams of dye of general formula (III-C) (orange) And 60 grams of dispersant MF, after adding water and blending, grind and disperse with a grinder until the particle size of the disperse dye is 1-3 μm, stop grinding. Then, the black dye powder (disperse dye composition) was obtained through high-temperature spray drying.

Abstract

The invention discloses a disperse dye composition, which consists of a dye A shown as a general formula (I), a dye B shown as a general formula (II), a dye C shown as a general formula (III) and an aid D, wherein in the formulae (I), (II) and (III), R1, R3 and R5 are independently hydrogen, methyl or methoxy; and R2, R4, R6 are independently hydrogen, nitryl, methyl or ethyl. The invention further discloses a dyeing method of a dacron and a preparation method of the disperse dye composition. The disperse dye composition provided by the invention has the advantages of high dispersing performance and oxidation resistance, and is suitable for a processing technology for pretreating and dyeing the dacron in one bath in the presence of an oxidant; and the dacron obtained by dyeing the disperse dye composition has the advantages of bright chromatic light, high soaping fastness, high dry rubbing fastness and superior wet rubbing 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...
