Abstract

The invention relates to the technical field of textile printing and dyeing, in particular to a method for improving active dyeing depth of a pure cotton fabric. According to the method for improvingthe active dyeing depth of the pure cotton fabric, the pure cotton fabric is dyed by the process of pressing, rolling and stacking, drying, steaming and color fixing, wherein the steaming and color fixing process comprises the steps of padding and color liquid fixing, steaming, water washing and soaping. According to the method for improving the active dyeing depth of the pure cotton fabric, the problem that the color quantity is low in continuous rolling dyeing is solved, the dyeing depth of the printed and dyed fabric can be improved by 25% or above on the original basis, the washable colorfastness of the dyeing fabric reaches 4 grade or above, the abrasion color change can reach 4 grade or above, the dry friction color fastness reaches 4 grade or above, the wet friction color fastnessreaches 3 grade or above, and the color change delta E after 30 times of water washing is within 0.5.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a method for increasing the reactive dyeing depth of pure cotton fabrics. Background technique [0002] Pure cotton fabrics are mostly dyed with reactive dyes, and the dyeing methods are divided into exhaust dyeing and pad dyeing, of which pad dyeing is divided into continuous pad dyeing and intermittent cold pad-batch dyeing. Continuous pad dyeing is favored by many printing and dyeing enterprises because of its high production efficiency, but this dyeing method has the disadvantage of low color yield, and some deep and thick colors cannot reach the ideal dyeing depth, while intermittent cold pad batch Although dyeing has high dyeing depth, it has the disadvantages of long time consumption and low production efficiency. How to efficiently improve the depth of reactive dyeing has become a difficult problem that needs to be broken through. [0003] Patent CN10...
