Abstract
[Object] In a fishing line for capturing large fishes made by a polyvinylidenefluoride resin filament, a polyvinylidenefluoride resin filament wherein even by enhancing the tensile strength at break by enlarging the filament diameter than that of usual fishing line, an appropriate tensile elongation at break can be obtained, so that the rapid and enormous impact generated when large fishes have taken the bait can be reduced, and that has a homogenous fiber structure which generates almost no inner cavity when forming a filament with a large diameter, is developed.
Claims6
A polyvinylidenefluoride resin monofilament, comprising:
- a polyvinylidenefluoride resin (a);
- and
- a copolymer of vinylidenefluoride and fluoroalkene (b),
- wherein the polyvinylidenefluoride resin monofilament is formed by a polyvinylidenefluoride resin composition (A) including (a) and (b) as composition ingredients,
- wherein the fluoroalkene content in the polyvinylidenefluoride resin monofilament is 1 mass % or more and less than 6 mass %, and the polyvinylidenefluoride resin monofilament has a monofilament diameter of 0.5 mm or more, and
- wherein the monofilament diameter is 0.5 to 3 mm, there is no spread of cavity with a rough diameter of 0.5 mm or more in the fiber axis direction of the oriented monofilament resulting from a cavity generated in unoriented monofilament, that the tensile strength at break is 600 MPa or more and the tensile elongation at break is 15 to 35%.
