Embodiment 1

[0065] A preparation method for a synthetic thickener for novel dye printing, comprising the following steps:

[0066] 1), 12 parts by weight of acrylic acid and 5 parts by weight of methacrylic acid are neutralized with 20 parts by weight of a neutralizer (30% potassium hydroxide aqueous solution) to obtain a neutralized solution with a pH value of 6.0 to 6.2, and the neutralized solution is mixed with 8 parts by weight of acrylamide, 0.01 part by weight of a cross-linking monomer (N,N'-methylenebisacrylamide), 0.1 part by weight of a water-soluble dispersion stabilizer and 10 parts by weight of deionized water are uniformly mixed to obtain an aqueous phase;

[0067] 2), add 15 parts by weight of No. 10 white oil, 2 parts by weight of oil-soluble emulsifier (Span60), 0.1 part by weight of reactive nonionic emulsifier and 2 parts by weight of oil-soluble monomer (methyl acrylate, methyl acrylate) in the reactor methyl acrylate, butyl acrylate and hydroxyethyl acrylate) to form...

Embodiment 2

[0083] This example is based on Example 1, and the difference from the example is that the raw materials for preparing the synthetic thickener, the ratio between the raw materials and the parameters are adjusted, as shown in Table 3,

[0084] The synthetic thickener prepared by the method described in this embodiment is composed of the following parts by weight:

[0085] 0.5 parts by weight of reactive nonionic emulsifier, 1 part by weight of water-soluble dispersion stabilizer, 20 parts by weight of water-soluble monomer, 4 parts by weight of oil-soluble monomer, 0.05 part by weight of crosslinking monomer, 28 parts by weight of neutralizer, 2.4 parts by weight of oil-soluble emulsifier, 2.4 parts by weight of inverse emulsion, 0.10 parts by weight of initiator, 18 parts by weight of white oil, and 15 parts by weight of deionized water.

Embodiment 3

[0087] This example is based on Example 1, and the difference from the example is that the raw materials for preparing the synthetic thickener, the ratio between the raw materials and the parameters are adjusted, as shown in Table 3,

[0088] The synthetic thickener prepared by the method described in this embodiment is composed of the following parts by weight:

[0089] 0.8 parts by weight of reactive nonionic emulsifier, 2 parts by weight of water-soluble dispersion stabilizer, 20 parts by weight of water-soluble monomer, 6 parts by weight of oil-soluble monomer, 0.05 parts by weight of cross-linking monomer, 30 parts by weight of neutralizer, 3.5 parts by weight of oil-soluble emulsifier, 3.5 parts by weight of inverse emulsion, 0.2 parts by weight of initiator, 23 parts by weight of white oil, and 26 parts by weight of deionized water.

Abstract

The invention discloses a novel synthetic thickener for pigment printing as well as a preparation method and application thereof. The novel synthetic thickener is prepared from a reactive nonionic emulsifier, a water-soluble dispersion stabilizer, a water-soluble monomer, an oil-soluble monomer, a cross-linking monomer, a neutralizing agent and an oil-soluble emulsifier as raw materials, and white oil as a solvent through inverse emulsion polymerization under the action of an initiator. Due to addition of the water-soluble nonionic emulsifier and the water-soluble dispersion stabilizer, not only are the electrolyte resistance and the anti-bleeding property of the novel synthetic thickener disclosed by the invention improved, but also the water retention property, the stability and the washing easiness of the novel synthetic thickener can be improved, and the paste removal rate of a printed fabric can be increased.

Description

technical field [0001] The invention relates to a novel synthetic thickener for dye printing and its preparation method and application technical field, in particular to a novel synthetic thickener for dye printing and its preparation method and application. Background technique [0002] Dye printing has the advantages of bright color, complete color spectrum, excellent fastness of printed fabrics, soft fabric feel and simple process, and has been widely used all over the world. Dye printing mainly includes reactive dye printing and disperse dye printing. Reactive dye printing paste is composed of printing paste, reactive dyes, soda ash, resist salt, urea and water, and disperse dye printing paste is composed of printing paste, disperse dyes, urea and water. In the process of dye printing, the performance of the printing paste plays a vital role in the printing effect. It can control the rheology, permeability and migration of the color paste, and is the most important fact...
