Abstract
The invention provides a discharge additive of a polyester fabric. The discharge additive is prepared from, by weight, 50-73% of deionized water, 1-5% of phosphoric acid, 15-25% of a reducing agent, 1-5% of an emulsifier and 10-15% of a thickening agent. A printing paste of the polyester fabric comprises 94-100% of the discharge additive and 0-6% of a P type disperse dye. The invention also provides a discharge printing method of the polyester fabric. The method comprises the following steps of (1) printing by the printing paste, wherein the printing paste is applied on the surface of the colored polyester fabric for printing to form a pattern with colors; (2) aging, wherein the reducing agent performs reduction on the original disperse dye applied on the surface of the polyester fabric; (3) removal of paste through washing. The process is simple, saves the energy and reduces the consumption. The discharge additive has good stability, therefore, the effect can be achieved that the polyester fabric is subjected to printing after high-temperature dyeing by using the printing paste with the discharge additive, and the energy and the time are saved. The polyester fabric obtained by printing after high-temperature dyeing has excellent fastness in various aspects, uniform discharge printing and soft and full hand feeling.
Description
Technical field [0001] The invention belongs to the field of textile printing and dyeing, and particularly relates to a discharge aid, printing paste and a discharge printing method for polyester fabrics. Background technique [0002] Polyester fiber (POLYESTER FIBERS), commonly known as "polyester". It is a synthetic fiber obtained by spinning polyester formed by polycondensation of organic dibasic acid and diol, referred to as PET fiber, which belongs to polymer compound. Invented in 1941, it is currently the largest variety of synthetic fibers. The biggest advantage of polyester fiber is that it has good wrinkle resistance and shape retention, and has high strength and elastic recovery. It is durable, wrinkle-resistant, non-ironing, and non-sticky. The dyeing of polyester fibers generally requires the use of disperse dyes. [0003] Disperse dyes have the following characteristics: [0004] (1) Disperse dyes are the most important and main category in the dye industry. They do...
