Abstract

The invention provides a fabric printing and washing process which is simple and can improve printing quality and ensure beautiful colors. The process comprises the following steps: 1, selecting a fabric and performing dust removal treatment on the fabric; 2, performing primary printing treatment: performing printing treatment on the pre-treated fabric; 3, performing primary washing: adding sodium carbonate into a water tank to regulate the pH value to 10 to 11, adding 1 to 3 parts of a CD anti-staining agent, and performing washing with 30 to 45 DEG C water; 4, drying a semi-finished product fabric in a dryer at drying temperature of 120 to 130 DEG C; 5, performing secondary printing treatment: spraying a color fixing agent onto the surface of a pattern; 6, performing secondary washing: adding acetic acid into the water tank to regulate the pH value to 4 to 4.5, adding 5 to 7 parts of a KNR color fixing agent, and performing washing with 50 to 60 DEG C water; 7, performing washing with clear water and drying. According to the process, the printed pattern is delicate, beautiful in color, highly layered, fast in coloring and low in fading rate.

Description

technical field [0001] The invention relates to the field of fabric printing and dyeing, in particular to fabric printing and washing processes of fabrics. Background technique [0002] Fabric printing, also known as fabric printing, is the process of using dyes or paints to form patterns on fabrics. Printing is partial dyeing and requires a certain degree of color fastness. Currently commonly used printing technology mainly includes mechanical printing, which is completed by a printing machine at one time, and the printing machine is a single machine. The disadvantage of machine printing is that the printed graphics are rough, the colors are not bright enough, and the layering is poor. Contents of the invention [0003] Aiming at the above problems, the present invention provides a fabric printing and washing process with simple process, improved printing quality and bright colors. [0004] The technical solution of the present invention is: comprising the following ste...
