Objective: Our main objective is to do X-ray diffraction (XRD) analysis of polyethylene terephthalate (PET) fibres obtained from different manufacturers in India. It is to determine whether this physical characteristic could be used in differentiating these fibres of one type or not. Method: X-ray diffraction patterns of the fibres of 8 samples were obtained using a Phillips PW 1840 X-ray Diffractometer. Findings: The results indicate that X-ray diffraction method may not provide definite clue to the identification of fibres, which are chemically similar but originating from different sources. However, more detailed studies are required in order to confirm the inappropriateness / appropriateness of the X-ray method. On the other hand, we have differentiated these fibres based on their tensile behaviour.Applications: The method has applications in forensic science investigations for identification and comparison of PET fibres.
Keywords: Degree of Crystallinity, Polyethylene Terephthalate (PET) Fibres, X-ray Diffraction (XRD)
