	abstract = {The usage of polyester (PET) in fabrication is increasing day by day due to its properties, ease of physical and chemical
modification. The aim of this work is to understand the effect of temperature on Polyester (PET) during knitting. For
checking the rise of temperature Infrared (IR) camera is used. Microscopic images are used for studying the effect of
temperature  on  fibre/yarn  structure.  Morphological  analysis  is  also  done  by  X-ray  diffraction  (XRD)  which  shows
disturbance of polymeric chains, causing change in crystal size due to elevated temperature. The beads formation and
filament breakage are clearly seen in images. Due to this knitting fault, shade variation after dyeing occurred. It is
concluded that structural morphology of polyester yarn changes due to friction of yarn with knitting machine parts. Fabric
appearance and fabric quality also disturbed which leads to rejections and high losses.},
