Abstract
A leader for fly fishing which has a high knot strength and a high tensile tenacity, is free from the formation of a shape-unstable portion (constriction) having a smaller diameter than an average thread diameter of the tippet section and the occurrence of melt fracture at a connecting portion between the tapered section and the tippet section, and shows an excellent natural drift property, can be produced by using a vinylidene fluoride-based resin having an inherent viscosity of 1.0 to 1.7 dl/g.
Claims4
A leader for fly fishing comprising a vinylidene fluoride-based resin having an inherent viscosity of 1.0 to 1.7 dl/g, and comprising a butt section, a tapered section and a tippet section,
- the thread diameter of the butt section being 300 to 800 μm, the thread diameter of the tippet section being 50 to 600 μm, and the ratio value of the thread diameter of the tippet section to that of the butt section being 0.1 to 0.7.
