Description

technical field

[0001] The invention relates to a kind of dyeing equipment used in textile, dyeing and finishing industries, in particular to a supercritical carbon dioxide fluid dyeing device with a purifier. Background technique

[0002] The traditional dyeing of textiles is a wet chemical process, which consumes a lot of water resources and chemicals, and produces a large amount of high-concentration, high-COD colored wastewater, which has caused serious pollution to the surrounding waters and ecological environment.

[0003] At present, as a new type of green dyeing and finishing technology, supercritical carbon dioxide dyeing technology has made staged progress, and the joint exploration and research on its process conditions, dyeing mechanism and dyeing equipment has been relatively mature. However, since dyeing needs to be realized through special dyeing equipment, the one-time input cost is relatively high. In addition, because the existing equipment is a single dev...
