Conference paper


Unmodified polypropylene fiber is difficult to dye due to the absence of dye sites in the molecular chain. Further, the high crystallinity is a deterrent to the diffusion of dyes. Because of its hydrocarbon nature and high crystallinity, unmodified polypropylene fiber is likely to be penetrated only by oleophilic dye molecules. Since smaller amounts of oleophilic dyestuffs are available for the penetration of such a dye molecule, either the pure hydrocarbon nature of the polymer must be changed or some submicroscopic discontinuities with high interfacial energy should be created within the fiber for dye molecules.
