  • Radiopaque monofilament for contrast X-ray radiography
    Patent number: 7998576
    Abstract: Disclosed is a monofilament allowing contrast X-ray radiography. At least part of the monofilament is formed of a thermoplastic resin containing a radiopaque agent. The monofilament contains the radiopaque agent in the thermoplastic resin in a content of 30 to 80% by mass, and has a Young's modulus of 0.1 to 5.0 cN/dtex and a fineness of 500 to 20000 dtex.
    Type: Grant
    Filed: November 7, 2008
    Date of Patent: August 16, 2011
    Assignee: Unitika Ltd.

  • X-RAY OPAQUE FILAMENT, X-RAY OPAQUE COVERED FILAMENT AND FIBER STRUCTURE USING SAID X-RAY OPAQUE FILAMENT AND/OR X-RAY OPAQUE COVERED FILAMENT
    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. A fiber structure is provided which includes the X-ray opaque filament and/or the X-ray opaque covered filament.
