Problems solved by technology

In recent years, with the improvement of living standards, people have become interested in the trace elements needed by humans in sodium alginate. Sodium alginate has begun to be transformed into medical and edible aspects, resulting in an increase in its price and an increase in printing costs.
[0004] At present, there are no reports of glycerin, PEG 200 blending instead of urea for reactive dye printing, and glycerin, PEG200 blending instead of urea, and thickener PTF-RT instead of sodium alginate paste for reactive dye printing.

Embodiment 1

[0020] The urea-free reactive dye printing paste of the present embodiment is made from the raw materials of the following weight ratio: reactive red K-2G 1%, PEG 200 0.5%, glycerin 0.5%, sodium bicarbonate 2% , anti-staining salt S 1%, thickener PTF-RT 5%, the balance is water.

[0021] The printing process of the urea-free reactive dye printing paste of the present embodiment to cotton fabrics, the steps are as follows: Weigh the PEG 200 and glycerin of the formula amount, add an appropriate amount of water to fully dissolve it, and then add the formula amount of anti-staining salt S , fully stirred to dissolve the anti-staining salt S to obtain a mixture A; weigh the reactive dye of the formula amount, add a small amount of distilled water to make a paste, pour it into the mixture A, and stir fully to dissolve the reactive dye to obtain a mixture B; then Mixture B is slowly added to the diluted thickener PTF-RT in the formula amount, pour the remaining water, stir well, add...

Embodiment 2

[0023] The urea-free reactive dye printing paste of the present embodiment is made from the raw materials of the following weight ratio: reactive red K-2BP 1.5%, reactive red M-8B 0.5%, PEG 200 0.5%, glycerin 1%, sodium bicarbonate 2%, anti-staining salt S 1%, thickener PTF-RT 6%, the balance is water.

[0024] The printing process of the urea-free reactive dye printing paste of the present embodiment to cotton fabrics, the steps are as follows: use reactive red K-2BP 1.5%, reactive red M-8B 0.5%, PEG 200 0.5%, glycerin 1%, Sodium bicarbonate 2%, resist salt S 1%, thickener PTF-RT 6%, the balance is water printing paste (preparation method is the same as Example 1) to print on cotton fabrics, and then dry at 90°C for 6min , steamed at 105°C for 7 minutes, and then post-treatment. The post-treatment process includes cold water washing, hot water washing, neutral soap washing, hot water washing, cold water washing, and drying.

Embodiment 3

[0026] The urea-free reactive dye printing color paste of the present embodiment is made from the raw materials of the following weight ratio: reactive yellow K-RN 3%, PEG 200 1%, glycerin 1%, sodium bicarbonate 2.5% , anti-staining salt S 1%, thickener PTF-RT 4%, the balance is water.

[0027] The printing process of the urea-free reactive dye printing paste of the present embodiment to cotton fabrics, the steps are as follows: use reactive yellow K-RN 3%, PEG 200 1%, glycerin 1%, sodium bicarbonate 2.5%, resist Salt S 1%, thickener PTF-RT 4%, the balance is water printing paste (preparation method is the same as Example 1) to print on cotton fabrics, then dry at 80°C for 7min, steam at 102°C for 10min, and then Carry out post-processing, the post-processing process includes cold water washing, hot water washing, neutral soap washing, hot water washing, cold water washing, and drying.

Abstract

The invention discloses urea-free active dye printing color paste and a printing technology thereof. The printing color paste is prepared from, by weight, 1%-10% of active dye, 0.5%-3% of PEG 200, 0.5%-3% of glycerol, 2%-5% of sodium bicarbonate, 0%-1% of sodium carbonate, 1% of reserve salt S, 3%-6% of a thickening agent PTF-RT and the balance water. A cotton fabric is printed through the printing color paste according to the processes of printing, drying, steaming and aftertreating, and the printed fabric is bright in color and luster and good in color fastness; urea is replaced with glycerol and PEG 200 for active dye printing, and therefore the problem that water eutrophication is caused by ammonia nitrogen compounds in wastewater can be thoroughly solved. The thickening agent PTF-RT is a high-concentration and high-quality synthetic thickening agent which is specially developed for active dye printing of the fabric, and the production cost is reduced by replacing sodium alginate with the thickening agent PTF-RT for active dye printing.

Description

technical field [0001] The invention belongs to the technical field of fabric printing, and in particular relates to a urea-free reactive dye printing paste which uses PEG 200 and glycerin instead of urea, and uses a thickener PTF-RT instead of sodium alginate raw paste and a printing process thereof. Background technique [0002] Reactive dyes have complete chromatograms, bright colors, excellent color fastness, and simple printing process. They are one of the dyes commonly used in cotton fabric printing. Reactive dye molecules contain water-soluble groups, which can be directly dissolved in water. However, during printing, due to the high concentration of dyes, it is difficult to dissolve the dyes. It is usually necessary to add a co-solvent to help the reactive dyes dissolve. After reactive dye printing, the dye is transferred from the size film to the fiber during the steaming process, diffuses into the fiber, and combines with the fiber in the form of a covalent bond. ...
