Supercritical CO² Fluid Dyeing
Waterless dyeing，Easy-drying
Not suitable for natural textile fibers such as cotton, wool and silk etc.- Super high pressure requirement leads to safety issue and difficulty for quality control.
- Much higher dyeing cost makes it not suitable for mainstream textile dyeing.
Low-pressure Waterless Dyeing Technology
A breakthrough low-pressure waterless dyeing technology has been developed by Green Universe Textile Technology which has a great safety profile and much better cost structure than CO2 Dyeing
- Easy recovery Non-aqueous medium with great safety and eco-friendly profile
- Dyeing fastness, uniformity, up-taking rate and fixing rate are all comparable to those of traditional dyeing
- Improved dye formulas and auxiliary chemicals
- Color brightness is even better than aqueous dyeing
- Dyeing under near atmospheric pressure
Low-pressure Waterless Dyeing Technology
——Dyeing Principle
Disperse dyes can be partly dissolved and dispersed by the specialty dyeing medium, and a dyeing accelerant can be used to control the solubility of the dye to promote the dye uptake.
Low-pressure Waterless Dyeing Technology
——Dyeing process
Waterless：Waterless process withmuch reduced amount ofdispersant, alkali andreducing powder.
Washing：After dyeing, the mediumwas used to clean the surface of the fiber to increase the color fastness.
Recycling：Recycling of medium after dyeing and washing.
