Continuous dyeing supercritical fluid system and process

Abstract

The continuous dyeing supercritical fluid system for continuous industrial production includes one supercritical fluid supplying device, at least two dyeing circulation devices and one supercritical fluid recovering device communicated successively. Each of the dyeing circulation devices includes one dye kettle and one dyeing kettle communicated mutually. The continuous dyeing supercritical fluid system of the present invention performs alternate dyeing continuously and has high production efficiency.

Description

technical field [0001] The invention relates to a dyeing device and a production process thereof in the field of textile dyeing, more specifically, to a production system for continuous dyeing using a supercritical fluid and a production process thereof. Background technique [0002] Most of the traditional fabric dyeing adopts wet dyeing process. For a long time, a large amount of waste water produced by wet dyeing has seriously polluted the environment. Although various enterprises have adopted corresponding sewage treatment methods, the actual effect of printing and dyeing sewage treatment is still not ideal. Seriously pollute the water resource environment and endanger people's life and health. [0003] In order to reduce environmental pollution and save production costs, in recent years, people have devoted themselves to the research of applying supercritical fluid to waterless printing and dyeing technology. The supercritical fluid dyeing process uses the better mass ...

Problems solved by technology

[0004] However, the current supercritical fluid printing and dyeing technology is still in the experimental research stage due to various limitations in equipment and technology. It can only realize a small amount of fabric dyeing and cannot carry out large-
