Abstract

The supercritical printing and dyeing process and apparatus consists of carbon dioxide cylinder, valve, membrane press, heating kettle, dyeing kettle, filter, dyeing kettle, separating kettle and carbon dioxide recovering bottle.

Description

Supercritical printing and dyeing process and device
Technical Field
The field belongs to the field of printing and dyeing.
Background
CO at normal temperature and pressure2Is gaseous, and when the temperature is raised and pressurized to be higher than 31.1 ℃ and the pressure is higher than 7.4MPa, the supercritical state is converted. At this time, CO2A certain amount of dye may be dissolved. Supercritical CO2The printing and dyeing technology is based on the principle that CO is introduced2Replacing water as medium, dissolving dye, and dyeing fabricAnd (6) dyeing. The supercritical device is an environment-friendly water-saving dyeing technology, accords with the development direction of the printing and dyeing industry, and is approved and welcomed by various large printing and dyeing manufacturers.
Disclosure of Invention
The invention relates to a supercritical printing and dyeing process and a device, which consists of a carbon dioxide gas cylinder, a membrane press, a heating kettle, a fuel kettle, a separation kettle and a recovery device.
The system utilizes the membrane press to pressurize and heat the carbon dioxide until the carbon dioxide reaches a supercritical state, and a certain amount of fuel can be dissolved to dye the fabric. And finally separating and recycling the carbon dioxide from the fuel in order to improve the utilization rate of the carbon dioxide.
Drawings
FIG. 1 is a schematic structural diagram of the present invention. Wherein figure number 1 is carbon dioxide gas cylinder bottle, figure number 2 is the valve, figure number 3 is the membrane press, figure number 4 is the heating cauldron, figure number 5 is the dyestuff cauldron, figure number 6 is the filter, figure number 7 is the dyeing cauldron, figure number 8 is the separation cauldron, figure number 9 is the carbon dioxide recovery bottle.
