X-ray contrast composite yarn and X-ray contrast fiber structure

摘要

PPROBLEM TO BE SOLVED: To provide an X-ray detectable composite thread and an X-ray detectable fiber structure which are easily found when left in the body since they take on particular X-ray detectable shapes. PSOLUTION: The composite thread includes an X-ray detectable fiber A formed of a thermoplastic resin containing an X-ray impermeable agent and a non-detectable fiber B not containing the X-ray impermeable agent. A detectable shape of the X-ray detectable fiber A has a winding part along the longitudinal direction of the composite thread. The X-ray detectable fiber structure contains the composite thread.
