Notes:
The structure, morphology, and some physical properties of nylon 6/polyethylene terephthalate (PET) blends (PET varying from 10 to 50%) have been reported here. Various techniques such as SEM, X-ray diffraction, birefringence, density, DTA, and DSC have been used. SEM studies revealed that in the blend PET is dispersed as spheres in the nylon 6 matrix. On melt spinning these are elongated in the form of rods and a fibril matrix-type morphology is developed. PET reinforces the (202, 002) lattice planes of nylon 6 up to a certain composition, resulting in increased crystallinity. Both nylon 6 and PET aid each other in mutual nucleation. The highly oriented and extended PET chains hold the nylon 6 molecular chains along their length resulting in increased orientation of the blend fiber system. All these studies further revealed that the improvement in some of the observed properties is due to the fibril-reinforced morphology and the crystallization behavior of the two components, especially that of nylon 6 in the presence of PET.
