Urea-free active dye printing color paste and printing technology thereof

[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...

[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.
