Application of Microwave Technology in Cotton Fabric Dyeing with Reactive Dyes

The influence of different factors on dyeing depth was explored when the cotton fabric was dyed with KN reactive dyes by microwave radiation,and the rubbing fastness and soaping fastness of the fabrics by conventional dyeing and microwave dyeing are determined.In addition,we also researched the effects of microwave heating on the dyeing properties of different dyes.The results show that: the dyeing time of cotton fabric by microwave heating can be greatly shortened,and the dyeing performance is similar to conventional dyeing process.
