DSC Studies on the Dyeing Properties of PLA Fiber

Abstract:

The dyeing properties of the polylactic acid (PLA) fiber with four different disperse dyes was studied. In the disperse dyeing process, differential scanning calorimeter (DSC) analysis was applied to test and analyze the changes of the glass-transition and melting temperature of the dyed and pure PLA fiber. The results indicated that not only the structure of the dispersed dyes and the dyeing conditions affected the dyeing performance of PLA fiber, but also the degree of the crystallinity of PLA fiber contributed to the final dyeing results. Moreover, the transformation of such crystallinity during the disperse dyeing process should be taken into account when the dyeing temperature was studied.
