Abstract

The invention discloses a processing method for increasing printing permeability of terylene fabric. The method comprises the following steps: preparing pre-treatment fluid containing an alkali agent,a high-molecular polymer dispersant, and water; performing dip padding on the terylene fabric with the pre-treatment fluid, placing the terylene fabric after dip padding treatment in a baking oven, washing the fabric with water having hardness being less than 10 mg / L, and drying the material; and performing further printing processing on the processed fabric, and the printing processing is characterized in that a tamarindus disperse printing paste is used for preparing a printing color paste; printing is carried out on the obtained terylene fabric, the printed terylene fabric is dried, backed, and subjected to reductive cleaning, washing with water, and drying.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing, in particular to a treatment method for improving the printing permeability of polyester fabrics. Background technique [0002] The basic component of polyester is polyethylene terephthalate. Because there are no specific active groups on its molecular chain and its polarity is small, it is difficult for dye molecules to enter the fiber during printing, and its permeability is poor. [0003] At present, there are two commonly used methods to increase the permeability of polyester printing. One is to use penetrants to improve the permeability of polyester fabrics. The function of penetrants is to reduce the surface tension of fibers. However, it also promotes the diffusion of the printing paste along the horizontal direction of the polyester fabric, causing the printing paste to bleed and the outline of the pattern is not clear; another method is to increase its penetration by increasing...
