The changes of the glass-transition and melting temperature of PLA fiber before and after dyeing have been investigated intensively by differential scanning calorimeter (DSC) analysis. Dyeing behavior of the knitted polylactic acid (PLA) fiber with four different disperse dyes has been studied, which indicates that the dyeing behavior of knitted PLA fiber has relation not only with the dye structure and processing performance, but also with its degree of the fiber crystallinity. During the dyeing of PLA fiber, its crystallinity was transformed, which should be taken into account in determining dyeing temperature.
