Problems solved by technology

[0022] The technical problem to be solved by the present invention is to provide a pre-printing slurry to solve the problems of large amount of sizing of hydrophilic fiber fabrics in the existing inkjet printing technology and large amount of wastewater discharge during subsequent washing; In direct-injection printing, only light colors can be printed, and medium and dark colors cannot be printed. In addition, it also solves the problems caused by wet-on-wet printing methods in flat screen printing, rotary screen printing and roller printing in existing textile printing. Insufficient patterns such as fuzzy pattern and dragging color

Embodiment 1

[0056] First, take some sodium alginate insoluble in organic solvents, add it into a grinder and grind it until the fineness is below 200 mesh, take it out for later use; then, add 8 kg of the above-ground sodium alginate fine powder, 1.5 kg of triethanolamine, 8 kg of urea in ethanol. Stir to fully dissolve urea and triethanolamine, and evenly disperse the fine powder of sodium alginate in the ethanol solution; finally, take 100 kg of the above solution, and mix high-viscosity polyvinyl butyral (viscosity 2%, 6000mPa.s, mPa.s) into the above solution to adjust the viscosity to 3000mPa.s, and thus it is configured as a pretreatment slurry for cotton inkjet printing.

[0057] Get some 40*40*13372 pure cotton poplin cloths, put them into an inkjet printing sizing machine, pour the above slurry into the sizing machine trough, sizing the surface of the above poplin, and dry it for later use.

[0058] Put the above-mentioned starched cotton cloth into the Italian MSJP6 digital pri...

Embodiment 2

[0066] First, take 20 kg of etherified seed glue (viscosity of 2%, 10000mPa.s) insoluble in organic solvents, add it to the ink ball mill, then add 30 kg of butanone, 50 kg of propylene glycol methyl ether, and grind for 48 hours to prepare Printing paste mother liquor, the fineness of the etherified seed gum in the test mother liquor is less than 800 meshes; then, take 90 kg of butanone and propylene glycol methyl ether mixture with a weight ratio of 1:1, add 5 kg of the etherified seed gum suspension After turbid printing mother liquor, add 5 kilograms of polyvinylpyrrolidone to adjust viscosity again, after stirring fully to dissolve, test its viscosity to be 3500mPa.s, namely prepare the pretreatment slurry for polyester inkjet printing.

[0067] Put the polyester pongee fabric on the cloth feeding frame of the coating machine, use a scraper to evenly coat the above slurry on the surface of the pongee fabric, dry it, and roll it up for later use.

[0068] Put the above fab...

Embodiment 3

[0074] First, take 39 kilograms of etherified cellulose, mix with 30 kilograms of butanone and 30 kilograms of butyl acetate, stir to form a suspension, add a ball mill to grind for 72 hours, and prepare a printing paste mother liquor, and detect the etherified cellulose in the mother liquor. The fineness is below 800 meshes; then, take 8 kilograms of the above-mentioned suspension, add 40 kilograms of methyl ethyl ketone, 50 kilograms of alcohol, add 1.2 kilograms of glycerin, 0.2 kilograms of citric acid, fully stir, glycerin and citric acid are fully dissolved; finally, Then add 5 kg of hydroxypropyl cellulose to adjust the viscosity to 800 mPa.s to prepare the pretreatment slurry for nylon mesh inkjet printing.

[0075] Take the nylon mesh cloth (the weight is 18 grams per square meter), install it on the gravure coating machine, use the 80-mesh gravure coating roller, coat the above-mentioned pretreatment slurry on the nylon mesh cloth, dry, roll up, spare.

[0076] Put ...

Abstract

The invention discloses a printing pre-treatment thickener. The pre-treatment thickener comprises the following components in percentage by weight: 1%-30% of printing past which is not dissolved into an organic solvent, 0.5%-10% of macromolecular substances which are dissolved into the organic solvent, 1%-20% of a water absorbent, 0.1%-8% of an acidic agent and 32%-97.4% of the organic solvent. The invention further discloses a preparation method of the thickener. According to the thickener and the method disclosed by the invention, the disadvantages in the prior art that the sizing amount of hydrophilic fiber textiles is great and the discharging amount of wastewater in an later water washing process is not enough are overcome; and furthermore, the disadvantages that hydrophobic textiles can be only printed with shallow colors but not medium and deep colors in a direct injection printing process are overcome.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing, in particular to a printing pretreatment slurry and a preparation method thereof. Background technique [0002] Inkjet printing, also known as digital printing, is printing using digital technology. Inkjet printing technology is a high-tech product that integrates machinery, computer, electronic information technology and gradually formed with the continuous development of computer technology. It first appeared in the mid-1990s. The emergence and continuous improvement of this technology , has brought a brand-new concept to the textile printing and dyeing industry, and its advanced production principles and means have brought an unprecedented development opportunity to the textile printing and dyeing industry. [0003] Simply put, the production process of inkjet printing is to input various digital patterns into the computer through various digital means such as scanning, digital phot...
