Abstract

The invention a printing and dyeing method, and especially relates to a production method for a polyester cotton oxygen bleaching and disperse dyestuff dyeing one bath process. The method comprises the following steps: selecting a sample cloth, carrying out pretreatment desizing, pre-setting a grey, singeing the grey, mercerizing, 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 the polyester cotton oxygen bleaching and disperse dyestuff dyeing one bath process 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.

Description

[0001] technical field [0002] The invention relates to a printing and dyeing method, in particular to a production method for polyester cotton oxygen bleaching and disperse dyeing in one bath. Background technique [0003] In the existing production process of polyester-cotton products, cotton oxygen bleaching and polyester disperse dyeing are divided into two-bath production and processing, because the pH value of the production treatment liquid involved in the two processing methods is different, if the two processing methods are combined in the same Bath treatment will affect their respective treatment effects. This processing method has long processing time, high energy consumption and high production cost. Contents of the invention [0004] The present invention mainly solves the deficiencies in the prior art, and solves the problems of long processing time, high energy consumption and high production cost in the production and processing of existing polyes...
