Problems solved by technology

Traditional discharge printing is realized by screen or paint printing, the process is cumbersome, and the amount of slurry is too large to cause water pollution, and these printing methods limit the characteristics of discharge printing to a certain extent, such as fine patterns, rich layers, and clear outlines.
[0003] Existing discharge printing compositions generally contain whitening agents, which release free formaldehyde during production and use, endangering human health and the ecological environment

Embodiment 1

[0028] According to the ink composition, the mass fraction is: 8% formaldehyde-free whitening agent, 8% N-methylpyrrolidone, 6% caprolactam, 0.8% sodium hexametaphosphate, 1.2% Ph regulator and 76% deionized water mixed together and fully stirred for 30 minutes to obtain a mixed solution of whitening ink, during which the dissolution of each component can be accelerated by heating.

Embodiment 2

[0030] According to the ink composition, the mass fraction is: 4% formaldehyde-free whitening agent, 5% caprolactam and N-methylpyrrolidone mixture, 5% polyethylene glycol 400, 0.1% sodium hexametaphosphate, 1% Ph regulator and 84.9% deionized water is mixed together and fully stirred for 45 minutes to obtain a white ink mixed solution, during which heating can be used to accelerate the dissolution of each component.

Embodiment 3

[0032] The mass fraction according to the ink composition is: 10% formaldehyde-free whitening agent, 20% caprolactam, 20% polyethylene glycol 200, 0.5% disodium edetate / 2.5% Ph regulator and 47% The ionic water is mixed together and fully stirred for 60 minutes to obtain a whitening ink mixed solution. During this process, the dissolution of each component can be accelerated by heating.

[0035] The black ink was prepared, and the components of each example are listed in Table 2.

[0036] Example 1:

[0037] According to the ink composition, the mass fraction is: 0.1% anti-pulling dye, 4% formaldehyde-free whitening agent, 5% N-methylpyrrolidone, 5% caprolactam, 0.1% sodium hexametaphosphate, 1% Ph regulator and 79.8 % of deionized water were mixed together and fully stirred for 30 minutes to obtain a mixed black ink solution, during which heating could be used to accelerate the dissolution of each component.

Abstract

The invention relates to a formula for discharge printing. The formula is used for preparation of white discharging ink and is characterized by comprising, by weight, 4 to 10% of a formaldehyde-free white discharging agent, 5 to 20% of a solubilizer, 5 to 20% of a humectant, 0.1 to 2% of an additive and 48 to 85.9% of deionized water. Ink is prepared from the formaldehyde-free white discharging agent or a mixture of the formaldehyde-free white discharging agent and discharge printing-resistant dyes, so discharge printing and inkjet printing can be integrated; thus, full play is given to the characteristics of delicateness, verisimilitude, hierarchy, brilliant and plump colors, sharp color contrast, edge sharpness, plump ground color, etc. of patterns obtained after discharge discharging.

Description

technical field [0001] The invention relates to a composition, in particular to a discharge printing composition. Background technique [0002] Discharge printing is printing on the dyed fabric. The printing paste (printing paste) contains a chemical substance (called whitening agent) that can destroy the dyeing dye, and the printing method of destroying or decolorizing the ground color dye at the printing place. . The pattern of discharge dyeing printing has the characteristics of meticulous, lifelike, rich layers, plump and gorgeous, strong color contrast, clear outline, and full background color. Traditional discharge printing is realized by screen or paint printing, the process is cumbersome, and the amount of slurry is too large to cause water pollution, and these printing methods limit the characteristics of discharge printing to a certain extent, such as fine patterns, rich layers, and clear outlines. . [0003] Existing discharge printing compositions generally co...
