Abstract

The invention relates to the technical field of textile processing, and particularly discloses a printing process of a polyester fabric. The printing process of the polyester fabric comprises the following steps: S1, conducting pre-processing; S2, padding in dye liquor; S3, conducting drying; S4, printing a dyeing-resistant paste; S5, post-processing to obtain a finished product polyester fabric, wherein the dyeing-resistant paste is prepared from the following raw materials in parts by weight: 2-4 parts of disperse dye; 1-2 parts of a penetrant; 4-6 parts of stannous chloride; 3-5 parts of tartaric acid; 40-60 parts of raw paste; 1-3 parts of a color fixing agent; 1-3 parts of a buffer agent; 4-6 parts of an ultraviolet light absorber; and 20-50 parts of water. Due to the adoption of the color fixing agent, the penetrant and the ultraviolet light absorber, the dyeing-resistant paste which is relatively uniformly mixed is obtained, the dyeing-resistant paste is promoted to be better dyed on a polyester fabric, the color fixation rate of the dyeing-resistant paste on the polyester fabric is improved to a certain extent, and the color fastness of the polyester fabric is improved.

Description

Technical field [0001] The present application relates to the technical field of textile processing, and more specifically, it involves a printing process of a polyester fabric. Background technique [0002] Polyester, also called polyester fibers, referred to as PET fibers, is a synthetic fiber obtained by polyester polyester polyester diolic acid and diol, which is excellent in comprehensive performance, and therefore applies more extensive in textiles. . [0003] In the relevant technique, the printed method of polyester fabric has direct printing, dyeing printing and transfer printing. Dry printing is a process of processing after printed, and the printing slurry contains chemicals (anti-dyeing agents) capable of destroying or preventing color dyes. The colored dyes in the printing place cannot be on the fabric, and the fabric is after washing. The printing is a white pattern, called anti-white printing; if it is in the same way, the printing slurry also contains a dye that d...
