Zusammenfassung: | To provide a contrast thread having a contrast property and drawability and capable of maintaining uniform tensile strength in a wide elongation range.SOLUTION: There is provided a contrast thread 1 comprising: a core part 11 including a plurality of bundled strands (first strand 111, second strand 112, third strand 113) composed of a plurality of types having different characteristics of tensile stress with respect to elongation; and a sheath part 21 which is arranged so as to cover the outer periphery of the core part 11 and is made of a resin 211 containing a radiopaque material 212.SELECTED DRAWING: Figure 2
【課題】造影性、延伸性を有すると共に、広い伸度範囲で均等な引張強さを維持することが可能な造影糸の提供を目的とする。【解決手段】造影糸1は、伸度に対する引張応力の特性が互いに異なる複数種からなる複数本の素線(第1素線111、第2素線112、第3素線113)を束ねた芯部11と、芯部11の外周を被覆するように配置され、X線不透過性材料212を含む樹脂211で形成された鞘部21と、を備えている。【選択図】図2 |
