Document Type and Number:
WIPO Patent Application WO/2021/003943
Kind Code:
A1
Abstract:
Disclosed is a dyeing and finishing process for a highly elastic polyester composite fabric, the dyeing and finishing process comprising a pre-treatment process, a dying process and a setting process, the pre-treatment process comprising an open-width desizing process, a cylinder scouring process, a pre-setting process and a slack alkali weight reduction process, which are performed successively. The dyeing agent used in the dyeing process is composed of a dyeing auxiliary agent and a dye, the dye being a disperse dye. The dyeing process uses a high temperature high pressure airflow dyeing machine, wherein when the temperature in the dyeing cylinder of the dyeing machine reaches 45°C, the dyeing auxiliary and the disperse dye are each injected, and the dye bath is at a pH of 5-6. The dyeing and finishing process can enhance the effectiveness of dyeing of a fabric, such that the dyeing evenness and the color fastness of the fabric meet customer requirements, and does not damage the elasticity of the fabric, such that the fabric has good shape memory, soft hand feel and good dimensional stability.
