Problems solved by technology

[0006] Today, as the requirements for energy saving, energy saving and emission reduction are getting more and more attention, it is necessary to develop new polyester fabric printing technology, which requires short printing process, low water consumption and low waste water discharge. It also has the advantages of excellent printing color fastness and soft fabric feel; at the same time, it is necessary to avoid the disadvantages of large water consumption and large waste water discharge by direct printing, and avoid hard or rough hand feeling and poor color fastness of pigment printing Shortcomings

Embodiment 1

[0066] 18.0g butyl acrylate, 2.5g acrylonitrile, 0.5g acrylic acid, 0.5g N-methylolacrylamide, 0.2g pentaerythritol tetraacrylate, 1.0g ethylene glycol dimethacrylate, 2.0g isotridecyl Acrylic ester, 0.5g emulsifier SP-80, 1.0g sodium dodecylsulfonate, 0.5g isomeric tridecyl alcohol polyoxyethylene ether (12) and 60.5g water were mixed, and fully stirred to form an emulsion. Dissolve 1.0 g of ammonium persulfate in 11.8 g of water at room temperature and stir well to form an initiator solution. Take half of the mass of the emulsion and half of the mass of the initiator solution and put them into the reaction device, stir while heating, and raise the temperature to 70°C. When the temperature reaches 70°C, under stirring state, slowly add the mixture of half of the mass of the remaining emulsion and the mass of the initiator solution dropwise at the same time, and the dropping time is 120 minutes. After the dropwise addition, the stirring was continued for 120 min at 74°C±2°C t...

Embodiment 2

[0068] Mix 12.0g of the original dye (2), 0.6g of isomeric tridecyl alcohol polyoxyethylene ether (8) potassium salt of phosphate, 0.6g of stearic acid polyoxyethylene ether (9), and 86.8g of water, and mix them in a sand mill Medium grinding until the particle size of the dye is 1-3 μm, to prepare 100 g of liquid disperse dye. Add 0.02g of H90 synthetic thickener and 2.0g of functional prepolymer A to the liquid disperse dye, and stir thoroughly to obtain slurry-like disperse dye A.

Embodiment 3

[0070] Mix 15.0g of the original dye (4), 1.0g of potassium tridecyl alcohol ether (6) phosphate ester, 2.0g of tridecyl alcohol polyoxyethylene ether (12), and 82.0g of water in sand Grinding in a grinding device until the particle size of the dye is 1-3 μm, and 100 g of liquid disperse dye is obtained. Add 0.02g of H90 synthetic thickener and 1.5g of functional prepolymer A to the liquid disperse dye, and stir thoroughly to obtain slurry-like disperse dye B.

Abstract

The invention discloses a slurry-like disperse dye and a preparation method and application thereof. The slurry-like disperse dye consists of a liquid disperse dye, a functional prepolymer and a synthetic thickener. Adding synthetic thickeners and functional additives to pulp disperse dyes can prepare a small amount of printing color paste, which can be used to print polyester fabrics on conventional screen printing machines or screen printing machines; The setting machine is subjected to high temperature treatment, the temperature is 180°C to 210°C, and the time is 45 to 120 seconds to prepare polyester printed fabrics. The slurry disperse dye of the present invention is used for polyester fabric printing, and has the characteristics of short printing process, the fabric feels soft, does not need to be post-treated, saves a lot of water resources and energy consumption, almost no waste water discharge, and the processing equipment is all Conventional equipment is a green printing processing technology.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a paste-like disperse dye and a preparation method and application thereof, which are used in a short-flow, energy-saving and emission-reducing printing process for polyester fabrics. Background technique [0002] In the 1930s, synthetic fibers ushered in a new era of textile fibers, and a variety of synthetic fibers came out one after another. The development of dyes has always been closely related to the development of fibers. In the textile printing and dyeing industry, powdery dyes are commonly used. When mixing pulp or preparing dye liquor, the dye dust is flying, which not only hinders environmental protection, but also often adheres to the ingredients used, or is suspended in the foam of the dye liquor, especially It is a disperse dye with low solubility and poor dispersibility, which is easy to form agglomerates, and is prone to defects in ...
