Abstract:

Polypropylene (PP) based polyblend fibres are made disperse and cationic dyeable by melt blending PP with cationic dyeable polyester (CDPET) and polystyrene (PS). The polyblend fibres were characterized for their thermal, mechanical and dyeability properties. Thermal analysis showed that the blend fibres are formed with reduced crystallinity favouring the dyeability of the fibres. The polyblend fibres were evaluated for disperse and cationic dyeing. The disperse dyeability increased in the range of 1050 to 1300%, while cationic dyeability in the range of 1300 to 1700% with excellent wash and light fastness. The increase in dyeability with respect to changes in the internal structure of the fibres is studied and optimal level of blending was predicted keeping in view of tenacity and thermal stability of melt blend fibres.
