Abstract

The invention provides a water-saving and energy-saving polyester dyeing method, and is applied to the technical field of polyester dyeing. The method comprises the steps of pretreatment, soft alkaline dyeing, saponification dyeing, color fixation and rolling; a water-saving and energy-saving polyester dyeing process is realized, and the outstanding advantages of low polyester dyeing cost, good environmental protection effect and high dyeing efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of polyester dyeing, in particular to a water-saving and energy-saving dyeing method for polyester. Background technique [0002] Polyester (polyester) is polyester fiber, invented in 1941, is an important variety in synthetic fibers; polyester is based on purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol ( MEG) is a fiber-forming high polymer prepared by esterification or transesterification and polycondensation of raw materials. The fiber made by spinning and post-treatment has the biggest advantage of good wrinkle resistance and shape retention. Polyester fiber is Among all textile fibers, the most processed chemical fiber varieties, the development of differentiated varieties, increasing the added value of products, and improving the economic benefits of enterprises are of great importance to the impact of the entire chemical fiber industry; product differentiation is t...
