Embodiment 1

[0040] The pure cotton plain weave fabric is deboiled, scoured and bleached for later use;

[0041] Industrial pure reactive yellow KN-G (reactive dye), industrial pure urea, food grade sodium alginate (thickener), industrial pure sodium carbonate (alkali agent), industrial pure hexadecimal Sodium phosphate and add deionized water to 100% to prepare color paste; the specific method is as follows:

[0042] ①Slowly add sodium alginate to deionized water and stir to prepare the original paste;

[0043] ②Dissolve the weighed dye, urea, and sodium carbonate in deionized water to form a solution;

[0044] ③ Add the dye solution and urea solution prepared in step ② to the original paste prepared in step ① in turn, stir while adding, and finally add the sodium carbonate solution prepared in step ②.

[0045] Print pure cotton plain fabric with prepared color paste;

[0046] Wrap the printed pure cotton plain weave fabric with a plastic film and stack it for the time specified in Tab...

Embodiment 2～ Embodiment 8

[0057] The procedure of Example 1 was repeated at the component contents and storage temperature and storage time specified in Table 1 below, the test results are listed in Table 1.

Embodiment 9～ Embodiment 11

[0059] Repeat the method of embodiment 1 by the specified component content and stacking temperature and stacking time in the following table 1, but replace reactive yellow KN-G with reactive brilliant blue KN-R, test result is listed in table 1 .

Abstract

The invention discloses a piling and printing method of a cotton fabric by a reactive dye. The method comprises the following steps: adding water into 1-3% by weight of the reactive dye, 2-6% by weight of urea, 15-20% by weight of a thicker and 1-5% by weight of an alkaline agent to 100% and preparing a mill base; then, printing the cotton fabric by the mill base; then, piling the printed cotton fabric for 6-10 hours at 25-35 DEG C for fixation; and finally, washing, soaping and washing and airing the fixed cotton fabric. The method disclosed by the invention is low in energy consumption, less in environmental pollution, high in color fastness, uniform in dyeing, simple in process and good in product quality.

Description

technical field [0001] The invention relates to a printing and dyeing method, in particular to a cotton fabric reactive dyestack printing method. Background technique [0002] Reactive dyes are also called reactive dyes, which have one or more active groups in the dye molecule, that is, reactive groups. Under certain conditions, they can interact with hydroxyl groups on cellulose fibers and protein fibers, polyamides, etc. A type of dye that undergoes bonding reactions such as amino groups on the fiber to form a covalent bond between the dye and the fiber. [0003] Reactive dyes have simple molecular structure, bright color, complete chromatogram, convenient use, and low cost. They contain sulfonic acid aqueous solution groups, which can be ionized into dye anions in water, and have high stability, diffusibility and level dyeing property to hard water. better. However, reactive dyes still have problems such as low color fixation rate, high-salt dyeing and high-concentratio...
