Purpose: of this paper was to evaluate the influence of X-ray irradiation on mechanical properties of polyester yarn used in production of vascular system prosthesis. Patients with such prosthesis are subjected to multiple X-ray radioscopic exposures. This can negatively influence prosthesis strength and durability. Design/methodology/approach: Polyester yarn tensile strength properties were measured before sterilisation and X-ray irradiation. Next a part of yarn was subjected to irradiation sterilisation. Sterilised and non-sterilised yarn was next exposed to multiple X-ray irradiation and to continuous irradiation. After each irradiation dose tensile strength and elongation at break were measured. Findings: The influence of X-ray irradiation dose on mechanical properties was evaluated. It was established that dose equivalent to multiple X-ray radioscopic exposures did not substantially influenced strength properties of polyester yarn. Research limitations/implications: To fully evaluate the influence of X-ray irradiation on prosthesis strength and durability working in human body environment it is planned to continue described research. Simultaneous influence of X-ray irradiation and body fluids on mechanical properties of polyester yarn will be tested. Practical implications: Research results proved that patients with polyester vascular prosthesis may be subjected to X-ray radioscopy without any anxiety concerning prosthesis strength properties or durability. Originality/value: The main research value is its basic conclusion that multiple X-ray irradiation does not significantly influence strength and flexibility of polyester yarn applied to vascular system prosthesis manufacture.
