preparation example Construction

[0066] The preparation method of the disperse dye composition specifically includes: mixing the above dye composition and a dispersing agent in a certain ratio, and micronizing by grinding to obtain the disperse dye composition.

[0067] Preferably, the mass of the diffusing agent is 0.8-5 times the mass of the dye composition.

[0068] Preferably, the diffusing agent is sodium methylene bismethyl naphthalene sulfonate, sodium methylene dinaphthalene sulfonate or a mixture of two, including diffusing agent NNO, dispersing agent MF, modified dispersion agent MF and dispersant CNF.

[0069] The preparation method of the disperse dye composition specifically includes: mixing the above dye composition and the dispersing agent according to the stated ratio, and micronizing by grinding to obtain the disperse dye composition.

[0070] The present invention provides a method for carrying out short-process alkaline dyeing of polyester fiber fabrics based on the above-mentioned dispers...

Embodiment 1

[0078] Mix 20 grams of dye (orange) with general formula (I-16) and 80 grams of dispersant MF with water, grind and disperse with a grinder until the particle size of the disperse dye is 1-3 μm, stop grinding, The orange dye powder was obtained by high temperature spray drying.

Embodiment 2

[0080] 5 grams of the dye (yellow) represented by the general formula (I-1), 35 grams of the dye (red) represented by the general formula (I-9) and 60 grams of dispersant MF are mixed with water and then mixed with a grinder Grinding and dispersing until the particle size of the disperse dye is 1-3 μm, stop grinding, and then spray-dry at high temperature to obtain orange dye powder (disperse dye composition).

Abstract

The invention discloses an isothiazole dye composition, which is selected from one or a mixture of more than two in a general formula (V) or selected from a mixture of one in general formulas (I) to (III) and one in the general formula (V). By adopting the dyeing method disclosed by the invention, a dye chromatograph of a disperse dye for dyeing under an alkaline condition is expanded, short-process dyeing process of the polyester fabric is achieved, and the original desizing and dyeing procedures of the polyester fabric are merged into one procedure, so that multiple water resources are saved, a plurality of washing procedures are reduced, consumption of an energy source also can be reduced, and the application limitation of alkaline dyeing of the disperse dye at present is thoroughly changed.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and in particular relates to an isothiazole dye composition and a short-process alkaline dyeing method for polyester fiber fabrics using the dye composition. Background technique [0002] Polyester fibers are dyed with disperse dyes, which were usually carried out in acidic medium. In order to achieve the requirements of energy saving, energy saving and emission reduction in polyester printing and dyeing, the dyeing medium of polyester fiber fabric must use alkaline medium, so as to realize the requirement of short dyeing process and achieve the purpose of reducing energy consumption. [0003] In order to achieve alkaline medium dyeing of polyester fiber, it is extremely important to select alkali-resistant disperse dyes. Due to the difference in structure, disperse dyes show different alkali resistance. Therefore, the selection of alkali-resistant disperse dyes is the basi...
