Title:
COTTON FIBER DYE FOR SUPERCRITICAL CO2 FLUID DYEING, AND METHOD FOR SYNTHESIZING SAME
Document Type and Number:
WIPO Patent Application WO/2017/028307
Kind Code:
A1
Abstract:
The present invention provides a cotton fiber dye for supercritical CO2 fluid dyeing, and a preparation method thereof. The cotton fiber dye has a sym-triazine reactive group enabling a bonding reaction with a cotton fiber, thereby fixing a dye onto the cotton fiber to achieve a dyeing effect. The cotton fiber dye contains a parent compound capable of dissolving in a supercritical CO2 fluid, thereby facilitating a use thereof in supercritical CO2 fluid dyeing applied to cotton. A sample undergoing the supercritical CO2 fluid dyeing using the cotton fiber dye of the present invention has high color fastness to dry or wet rubbing, and high fastness to staining in a washability test. Moreover, a method for synthesizing the cotton fiber dye of the present invention has a simple manufacturing process. Thus, the cotton fiber dye for supercritical CO2 fluid dyeing, and the method for synthesizing the same of the present invention have considerably broad application prospects.
