Abstract

Novel $CO_{2}$ laser drawing has been investigated by using a newly designed and constructed laser drawing machine, which has feed roller and take-up roller as in conventional roll drawing process. The $CO_{2}$ laser drawing of poly(ethylene terephthalate) (PET) fiber was performed with change of drawing conditions to improve mechanical properties of the PET fiber. The PET fiber were drawn continuously by $CO_{2}$ laser radiation perpendicular to the fiber axis. The physical properties of the $CO_{2}$ laser drawn PET fiber are studied by wide-angle X-ray diffraction (WAXD), birefringence, differential scanning calorimetry (DSC) and tensile testing. The improvement of mechanical properties of the PET fiber by $CO_{2}$ laser drawing is attributed to the development of more ordered crystallites and the formation of more perfect crystalline structures in the PET fiber.
