Research progress on clean dyeing and coloring technology for textiles in the context of dual-carbon
The"14th Five-Year Plan"of textile industry has pointed out the development direction of green and clean dyeing processes and technologies for dyeing and printing industry.Based on this perspec-tive,the dyeing of non-aqueous and less aqueous media such as supercritical CO2,ionic liquid and oil,new dyeing materials and technologies such as electrochemical dyeing,microbial pigment and biomimetic dyeing,as well as the application of microwave and ultrasonic technology in dyeing process were focused on.The principle,application status and advantages of various technologies were introduced.Clean dyeing processes and technologies,compared to traditional dyeing,had the characteristics of saving dye usage,shortening the process,saving energy and water,and reducing wastewater and exhaust emissions,which was an important aspect to promote the sustainable development of textile dyeing and printing industry.
