Abstract

The present invention is dyeing caldron of supercritical CO2 dyeing apparatus and relates to fabric dyeing technology. The dyeing caldron has one upper fabric baffle to form one upper cavity, one upper dye box in the upper cavity, one lower fabric baffle to form one lower cavity, one CO2 flowing channel between the lower fabric baffle and the inner caldron wall, one lower dye box in the lower cavity, one porous tube coaxial with the caldron fixed to the upper fabric baffle and the lower fabric baffle, and one stainless steel filtering net to cover the outer surface of the porous tube. The present invention integrates the functions of both dye caldron and the dyeing caldron, and has simplified conveying pipeline, lowered flowing resistance and simultaneous dye dissolving and fabric adsorption in the same caldron.

Description

technical field [0001] The invention relates to a dyeing device for spinning fiber fabrics, in particular to a supercritical carbon dioxide dyeing device. Background technique [0002] The dyeing and finishing industry is an indispensable industry in people's life and the national economy, but the dyeing and finishing industry has always been a large water-consuming and polluting household. According to incomplete statistics, domestic printing and dyeing enterprises discharge 3 to 4 million tons of sewage every day. It is conceivable that although the dyeing and finishing industry has its necessity, the pollution it causes, which endangers people's health and life and destroys the ecological environment, is indeed astonishing. It cannot but arouse the attention of the society and the government. Advanced industrialization The countries have all had painful lessons, and for this reason they have also adopted mandatory policies and made huge investments to solve environmental ...
