Polyester-mixed cotton cloth mercerizing machine and mercerizing process

Abstract

The invention relates to a polyester-mixed cotton cloth mercerizing machine and a mercerizing process. The mercerizing machine comprises a rack, wherein a first removing mechanism is arranged on the rack, and the first removing mechanism comprises a spraying box, a spraying device and a driving device; and the spraying box is arranged on the rack and contains cleaning liquid, the spraying device is arranged on the spraying box and sprays cloth, the spraying device comprises a spraying pump and a spraying pipe, the spraying pump is arranged on the spraying box, the spraying pipe is arranged onthe spraying box, a pipe opening of the spraying pipe faces the cloth, the driving device is arranged on the spraying box, the driving device comprises a driving roller and a driving piece, the driving roller is rotatably arranged on the spraying box and abuts against the cloth, and the driving piece is arranged on the spraying box and connected with the driving roller. The spraying pump is started to enable the cleaning liquid to be sprayed onto the cloth, so that alkali liquor on the cloth is cleaned up, the content of the alkali liquor when the cloth enters the next procedure is reduced, the influence of the alkali liquor on the next procedure is reduced, and the quality of the cloth is improved.

Description

technical field [0001] The present application relates to the technical field of mercerizing machines, in particular to a polyester-cotton cloth mercerizing machine and a mercerizing process. Background technique [0002] In the textile printing and dyeing industry, cotton fabrics and cotton yarns are bleached and dyed in order to increase the lasting luster of cotton fibers and the affinity to dyes, as well as to improve the dimensional stability of fabrics. Cotton fibers are mercerized with caustic soda. The mercerizing process is the process of increasing the luster of cotton yarn or cotton fabric through chemical action. Specifically, cellulose such as cotton and hemp is impregnated with sodium hydroxide, so that the fibers undergo irreversible swelling and cause the natural distortion of the longitudinal direction of the fibers to disappear. Then apply appropriate tension to the fiber, so that the fiber becomes a very smooth cylinder in the longitudinal direction, and p...

Problems solved by technology

[0004] For the related technologies mentioned above, the inventor thinks that there is the following defect: the cloth generally uses lye when it is spray-washed, so the lye contained in the cloth is more when the cloth is output outside the main body of the cloth clip mercerizing machine, so the lye will It will affect the subsequent process and reduce the quality of the fabric
