    Publication number: 20090302241
    Abstract: An X-ray opaque filament is provided, which is constituted of a filament formed of a thermoplastic resin containing an X-ray opaque agent and has a dry heat shrinkage of 3.5 to 0% at 130° C. An X-ray opaque covered filament is provided, which is formed by covering the periphery of the X-ray opaque filament with a covering fiber. Furthermore, an X-ray opaque filament is provided, which is constituted of a fiber formed of a thermoplastic resin containing an X-ray opaque agent and has an oil containing an ionic surfactant in a ratio of 0 to 10% by mass added thereto. An X-ray opaque covered filament is provided, which has a covering fiber formed of a thermoplastic resin having a lower melting point than the thermoplastic resin constituting the X-ray opaque filament.
