ABSTRACT

Dyeing and fastness properties of a dyeable PP fiber were examined with four different types of disperse dyes. It was found that the dyed PP fiber could be cleared by soaping without using sodium hydrosulphite, and that the heat setting above 140℃ resulted in the melting of the PP fiber. The rates of dyeing and the extents of exhaustion of three primary E type dyes were different with each other, the apparent color strength did not increase with increasing dye concentration, and color fastness to washing was not satisfactory. In the cases of both high wash fastness and high light fastness dyes, the rates of dyeing were slow and the extents of exhaustion were very low. On the other hand, the dyeing rates of three primary S type dyes were similar and the build-up properties were good with good color fastnesses. It might be concluded that the best disperse dyes for the dyeable PP fiber were S type dyes.
