Blends of polyethylene terephthalate (PET)/polypropylene (PP) and the ternary copolymer ethylene-acrylic ester-glycidyl methacrylate (EAG) as the compatibilizer were prepared using a twin-screw extruder. The thermal properties, densities and morphologies of the blends were determined using various techniques. Next, PET/PP blend fibres were prepared using a melt-spinning system, and their curl properties were investigated. Scanning electron microscopy (SEM) results showed that the number of PP

The melting temperature (T m ) and cooling crystallization (T cc ) values of PP in the PET/PP blends decreased significantly after the addition of 1% EAG. The density of the PET/PP blend fibres decreased significantly with increase in the EAG and PP contents. After curl formation, the curl length of PP in the fibres was shorter than that of PET.
