| 摘 要： | This paper deals with the dyeing of cotton fabrics with microwave irradiation.The compara-tive experiments of the microwave dyeing to the conventional dyeing were carried out and themechanism was also discussed.Being subjected to microwave irradiation,the penetration of dyesand chemicals into the fabric can be achieved in a short time with a good color yield.The irradiatedmaterials generate heat via dielectric heating by high frequency electro-magnetic field and as a re-sult,energy saving can be realized.Based on the examination and analysis with X-ray diffraction,IR,SEM,and XPS,the reduction in crystallinity,the formation of active carbonyl groups of freeradicals containing oxygen and the morphological changes in the irradiated cottom fibers werefound.All of these may be believed in favour of the dyeing process.
