Polypropylene (PP) based polymer alloy fibres consisting of varying quantity (5-20%) of polytrimethylene terapthalate (PTT) were meltspun to modify PP structure. The compatibility of blends, crystallization behaviour and structural changes of fibres were analyzed using wide angle X-ray diffraction, differential scanning calorimetry, birefringence, tensile properties and thermal stability. The polyblend fibres exhibited increased dyeability with increase in PTT content along with excellent wash and light fastness properties. The structure of modified blend fibre is compared with that of the pure PP fibre and the enhanced dyeability is discussed in the light of changes in internal structure of the blend fibres.
