Abstract

The invention relates to a printing and dyeing method, and especially relates to a grey dyeing production method for removing chemical pulp and oligomers. The method comprises the following steps: selecting a sample cloth, carrying out pretreatment desizing, 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, carrying out alkali amount reduction in a sample jar, designing a dyeing formula, carrying out jar dyeing on the 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 grey dyeing production method for removing chemical pulp and oligomers has the advantages of dyeing stability increase, effective increase of the one-time success rate, reduction of the dyeing repairing rate, and obvious energy saving and emission reduction effects, produced fabrics have good handle resilience, drapability and flexibility, and various quality indexes of the fabrics can meet requirements of clients.

Description

technical field [0001] The invention relates to a printing and dyeing method, in particular to a gray cloth dyeing production method for removing chemical pulp and oligomers. Background technique [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 Therefore, 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.
