Abstract:

Poly(ethylene terephthalate) (polyester) fibres were spun using a high-speed melt spinning method. By changing the spinning conditions, polyester fibres with differences in crystallinity, birefringence and melting point were obtained. The dyeing behaviour of these fibres was investigated using CI Disperse Red 1. The degree of crystallisation of polyester lowered the dyeability. The fibres with lower molecular orientation and larger crystallite size showed better dyeability.
