Problems solved by technology

[0002] In the printing and dyeing process of cationic products, fabric pretreatment and cationic dye dyeing are generally divided into two baths for production, because the pH value of the treatment liquid in the two processing methods is different, the pretreatment should be alkaline, while the cationic dye dyeing requires partial Acid; if the two processing methods are combined in the same bath, the respective processing or dyeing effects will be affected; develop a pre-treatment compounding agent that allows catabolic products to treat catabolic fabrics under acidic conditions , it is particularly important to change the production process of the pretreatment and dyeing process of the anodic adhesive, and to simplify the production process of the anodic adhesive
It is mainly able to solve the problems of long processing time, high energy consumption and high production cost of existing processing methods

Abstract

The invention relates to a printing and dyeing method, and especially relates to a production method for outside pasting product pretreatment and cationic dye one-bath process dyeing. The method comprises the following steps: selecting a sample cloth, pre-setting a grey, singeing the grey, preparing a complex formulation assistant according to a formula, using the complex formulation assistant according to a ratio, designing a dyeing formula, carrying out jar dyeing on the cloth sample, carrying out hot setting, singeing the obtained color body, washing by water, drying, carrying out oiling setting, carrying out after-finishing calendering, carrying out after-finishing full decatizing, and examining the obtained finished product. The production method for for outside pasting product pretreatment and cationic dye one-bath process dyeing has obvious energy saving and emission reduction effects, and the handle elasticity, the color fullness and various quality indexes of fabrics obtained in the invention can meet requirements of different clients.
