Problems solved by technology

However, synthetic thickeners have poor electrolyte resistance, and the printed fabric feels hard. This is a common defect of synthetic thickeners, and it is also a major obstacle for synthetic thickeners to replace sodium alginate.

Embodiment 1

[0018] The technological prescription of pure cotton fabric printing slurry of the present invention is calculated by each component by weight percentage:

[0019]

[0020] Preparation method of printing paste:

[0021] (1) Preparation of 4% sodium alginate: first add sodium alginate to water and stir until the sodium alginate is completely dissolved, prepare sodium alginate with a mass fraction of 4%, and set aside for 4 hours;

[0022] (2) Preparation of printing slurry: add 4% sodium alginate, thickener, urea, baking soda, soda ash, and anti-staining salt S to water in sequence according to the above process parameters and stir until uniform.

[0023] The application performance of the product after printing by this process: the color yield is 10% darker than the sample, the fineness is higher, and the dry / wet rubbing fastness: 3-4 / 2-3.

Embodiment 2

[0025] The technological prescription of pure cotton fabric printing slurry of the present invention is calculated by each component by weight percentage:

[0026]

[0027] Preparation method of printing paste:

[0028] (1) Preparation of 4% sodium alginate: first add sodium alginate to water and stir until the sodium alginate is completely dissolved, prepare sodium alginate with a mass fraction of 4%, and set aside for 4 hours;

[0029] (2) Preparation of printing slurry: add 4% sodium alginate, thickener, urea, baking soda, soda ash, and anti-staining salt S to water in sequence according to the above process parameters and stir until uniform.

[0030] The application performance of the product after printing by this process: the color yield is 10% darker than the sample, the fineness is higher, and the dry / wet rubbing fastness: 3-4 / 2-3.

Embodiment 3

[0032] The technological prescription of pure cotton fabric printing slurry of the present invention is calculated by each component by weight percentage:

[0033]

[0034] Preparation method of printing paste:

Abstract

The invention provides a pure cotton fabric coating paste and a preparation method thereof. The coating paste is prepared from the following components in percentage by weight: 30-40% of 4% sodium alginate, 1-2% of thickening agent, 5-8% of urea, 3-4% of baking soda, 3-4% of soda ash, 1-2% of reserve salt and the balance of water. The coating paste is low in cost, higher in printing effect fineness, high in color yield, wider in application range, and simple in preparation method.

Description

technical field [0001] The invention relates to the field of textile printing, in particular to a pure cotton fabric printing paste and a preparation method thereof. Background technique [0002] Sodium alginate is the most ideal paste for reactive dye printing of pure cotton fabrics. It has strong paste rate, good permeability, no reduction, and a wide range of applicable pH values. Sodium alginate is a natural polysaccharide compound extracted from kelp, and the preparation process is limited by resources. Moreover, with the continuous development of printing technology, sodium alginate has been gradually transformed into food products in recent years, and its price has increased, resulting in an increase in printing production costs. Therefore, in the past ten years, domestic and foreign research and development of pastes for reactive dye printing have turned to synthetic thickeners, mainly anionic polyacrylates, which have the advantages of fast paste formation, high co...
