Problems solved by technology

Due to the lack of good bonding fastness between the existing polyester antistatic agent and polyester fiber, it is easy to be removed together with the pretreatment agent in the process of reduction cleaning and water washing, especially in the presence of other pretreatment agents, polyester antistatic The combination fastness of the inkjet printing agent and polyester fiber is even worse. Therefore, it is difficult to obtain good antistatic property after inkjet printing, and it does not have washing resistance, and its durable antistatic effect is not good.
[0005] At the same time, in the prior art, in order to prepare ink-jet printed polyester fabric with good durable antistatic effect, it usually needs to be processed through a long industrial route, such as the two-bath process processing method, which is harmful to water, electricity, steam and other energy sources. Large consumption, not an ideal scientific production and processing method

Synthetic example 1

[0038] Mix 8.0kg butyl acrylate, 2.0kg styrene, 1.0kg ammonium persulfate, 4.0kg emulsifier AES and 39.0kg water, and fully stir to form an emulsion to obtain emulsion A1;

[0039] Take 36.0kg of emulsion A, 23.0kg of allyl alcohol polyoxyethyl polyoxypropyl ether (p=3, q=3) and 15.0kg of water and mix them, and fully stir them into an emulsion to prepare emulsion B1;

[0040] In the reaction device, add 18.0kg of emulsion A1, 1.0kg of ammonium persulfate, and 7.0kg of water to mix, and heat up to 80°C while stirring, and continue to react at this reaction temperature for 30 minutes; then slowly add 74.0kg of Emulsion B1: After the addition is complete, continue to react at 80-85°C for 100 minutes, and cool to obtain the pre-condensation body A.

Synthetic example 2

[0042] 12.0kg butyl acrylate, 4.0kg styrene, 1.0kg ammonium persulfate, 3.2kg emulsifier AES and 33.8kg water were mixed, and fully stirred into an emulsion to obtain emulsion A2;

[0043] Take 36.0kg of emulsion B1, 19.0kg of allyl alcohol polyoxyethyl polyoxypropyl ether (p=2, q=4) and 15.0kg of water and mix them, and fully stir them into an emulsion to prepare emulsion B2;

[0044] In the reaction device, add 18.0kg of emulsion A2, 0.5kg of ammonium persulfate, and 11.5kg of water to mix, and heat up to 80°C while stirring, and continue to react at this reaction temperature for 30 minutes; then slowly add 70.0kg of Emulsion B2: After the addition is complete, continue to react at 80-85°C for 120 minutes, and cool to obtain the pre-condensation body B.

Embodiment 1

[0047] 2.5kg of precondensate A, 1.0kg of pentaerythritol tetraacrylate, 0.4kg of carboxymethylcellulose, 0.2kg of potassium persulfate and 95.9kg of water were mixed to prepare pretreatment solution C1. Then the polyester fabric is padded with the pretreatment solution C1 and dried; then the required printing pattern is printed with an inkjet printer, and the inkjet ink is the D2551-R disperse red ink of DuPont Company of the United States. After the printing is completed, it is dried and baked on a heat-setting machine. The baking temperature is 170°C and the baking time is 60S. Finally, the above-mentioned polyester fabric was washed on a washing machine at a washing temperature of 80° C. and a washing time of 10 minutes; after washing, it was dried on a drying device to obtain an antistatic inkjet printed fabric.

Abstract

The invention discloses an antistatic preprocessing solution for polyester digital inkjet printing. The solution is specifically prepared from, by mass, 2.5-4.0% of a preshrinking body, 1.0-2.0% of acrosslinking agent, 0.3-1.5% of a thickening agent, 0.1-0.3% of peroxide and the balance water. A polyester fabric is padded with the preprocessing solution before inkjet printing, and the polyester fabric processed through the solution is subjected to inkjet printing so that the high coloring depth, excellent color fastness and excellent antistatic effect can be obtained and the antistatic performance can be durable. Meanwhile, processing devices used for the solution are all conventional devices, and a low-energy-consumption environmental-friendly one-step processing technology is realized.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to an antistatic pretreatment solution for polyester digital inkjet printing and its application in treating polyester fabrics. Background technique [0002] In the prior art, the common processing flow when carrying out digital inkjet printing to polyester fabric is: first padding pretreatment solution, drying; Then use disperse dye ink to print and dry on the digital inkjet printing machine; Then Carry out high-temperature dye hair color treatment and post-treatment (such as reduction cleaning or hot water washing), and finally make printed products by drying. [0003] There is a problem in the process of polyester fabric treatment. As a kind of hydrophobic fiber, polyester fiber is easy to generate static electricity, which affects the wearing performance. In order to improve the antistatic properties of polyester fabrics, manufacturers usually pad dyed or pr...
