Abstract

The invention discloses a cotton fabric printing and dyeing process, which comprises the following steps: S1. providing a cotton fabric to be printed and dyed, and then pretreating the cotton fabric to be printed and dyed, and the pretreatment comprises singeing and neutralization of the cotton fabric to be printed and dyed, scouring and bleaching with a liquid mixture formed by sodium hydroxide and hydrogen peroxide, and tensioning of the cotton fabric to be printed and dyed for treatment with a concentrated alkali; S2. dyeing the pretreated cotton fabric to be printed and dyed, during the dyeing, dipping the cotton fabric into a first dye solution for dyeing, then sending the cotton fabric into a second dye solution for secondary dyeing, after the dyeing, washing the cotton fabric with water, soap-boiling the cotton fabric, and drying; S3. printing the dyed cotton fabric, preparing printing slurry, coating the cotton fabric with the printing slurry, baking and steaming; and S4. finishing the printed cotton fabric. The cotton fabric printing and dyeing process is simple, and the operation is convenient. The knitted fabric printed by the method has the advantages of being not easy to decolor and long in service life, and good economic benefit is obtained.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a cotton fabric printing and dyeing process. Background technique [0002] Cotton fabric is a fabric formed by the regular movement of yarns through knitting to form loops, and the loops and loops are intertwined with each other. Specifically, in weft-knitted fabrics, each yarn forms loops in one course, and the loops formed by one yarn are arranged along the weft direction of the fabric; in warp-knitted fabrics, each yarn forms loops in each course. Only one or two loops are formed in the process, and then transferred to the next row to form loops. The loops formed by one yarn are arranged along the warp direction of the fabric. Therefore, one yarn can form a course in a weft-knitted cotton fabric, while many yarns can form a course in a warp-knitted cotton fabric. [0003] After the weaving of the cotton fabric is completed, the cotton fabric needs to be printed a...
