摘要：
The dyeing of cotton, modified previously by reaction with benzoyl chloride, has been carried out using disperse dyes in supercritical carbon dioxide at 100 degrees C and 300 bar and compared with the dyeing of polyester under the same conditions. The colour yields of fibres was assessed by K/S measurements before and after washing to investigate the quality of dyeing in this medium. Good colour intensity and wash fastness were obtained.
