Full-polyester fabric printing and dyeing process and method

Abstract

The invention discloses a full-polyester fabric printing and dyeing process and a method. The method comprises the following steps of preparation before printing and dyeing of full-polyester fabric, and preparation of clean water in the whole printing and dyeing process; putting the full-polyester fabric onto a goods checking station, and mainly checking the abnormalities of yarn drawing-out, pirnbarre, yellow spot, mildew spot and the like in a fabric blank; checking whether the fabric variety is matched with the required fabric variety or not; under the normal condition, checking each batch. The method has the advantages that by feeding potassium hydroxide into the softened clean water, the alkaline reduction treatment is performed on the full-polyester fabric; the concentration of thepotassium hydroxide in the clean water is effectively increased via the clean water with the temperature of 90 to 100 DEG C; by adding the full-polyester fabric, the alkaline reduction treatment can be effectively performed, so as to solve the problem of influence to the dyeing treatment of the full-polyester fabric due to higher concentration of alkaline in the existing full-polyester fabric; byusing the clean water to flush, the alkaline dirt at the outer surface of the fully-polyester fabric is cleared, thereby avoiding the influence to the treatment of bleaching due to bringing of the alkaline dirt into a reaction kettle.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing methods for all polyester fabrics, in particular to a short process and method for printing and dyeing all polyester fabrics. Background technique [0002] Polyester is an important variety of synthetic fibers, which is made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) through esterification or transesterification and polycondensation reactions. The obtained fiber-forming high polymer - polyethylene terephthalate (PET), the fiber made by spinning and post-processing. [0003] The existing polyester imitation silk fabric is a polyester fabric with a real silk appearance style woven from polyester filaments or short fiber yarns with round and special-shaped cross-sections. It has the advantages of low price, wrinkle resistance and non-ironing, and is very popular among consumers. There are: polyester silk, polyester crepe, polyester sat...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a short process and method for printing and dyeing of all polyester fabrics, which solves the problem of poor printing and dyeing effects of all polyester fabrics during the printing and dyeing process, which leads to the post-processing rate of all polyester fabrics, thereby reducing work efficiency. question
