PROBLEM TO BE SOLVED: To provide a fishline having high strength and abrasion resistance.SOLUTION: The fishline is obtained by hot-drawing a fishline of an ultrahigh molecular weight polyolefin fiber yarn at a temperature lower than the melting point. The fishline is preferably subjected to a braiding, twisting or covering treatment, or subjected to a combination of two or more kinds of these treatments.COPYRIGHT: (C)2006,JPO&NCIPI【課題】 高強力で耐摩耗性に優れている釣糸を提供する。【解決手段】 超高分子量ポリオレフィン繊維糸の釣糸を融解点温度未満にて加熱延伸する。【選択図】なし
