X-ray contrast yarn, X-ray contrast media covering yarn, wherein the X-ray contrast thread and, fibrous structure, or using X-ray contrast medium coated yarn

摘要

An X-ray contrast thread is constituted by fibers of a thermoplastic resin containing an X-ray opaque agent, dry heat shrinkage at 130 ℃ is 3.5 to 0%. An X-ray contrast covering yarn, around the X-ray contrast yarn described above is coated with a coated fiber. Also, an X-ray contrast thread and is constituted by fibers of a thermoplastic resin containing an X-ray opaque agent, oil is 0-10% by mass ratio of ionic surfactant component is given . An X-ray contrast covering yarn, and that is made up of a thermoplastic resin having a melting point lower than that of the thermoplastic resin is coated fiber constitutes the X-ray contrast thread. A fiber structure, the X-ray contrast yarns and, or include X-ray contrast media covering yarn.
