Fishing line and method for production thereof

A method for producing a fishing line, the method comprising melt-spinning a resin composition (C) containing 90 to 99.3% by weight of a polyamide resin (A) having a relative viscosity, as measured in a concentrated sulfuric acid solution, of 3.3 to 5 and 0.7 to 10% by weight of a polydimethylsiloxane having a number average molecular weight of 300,000 to 2,000,000 represented by the following formula (1) and then drawing it to obtain a monofilament:

• wherein substantially all the Rs are methyl groups and n is a natural number,
• wherein the polyamide resin (A) is a copolymerized polyamide resin including a caproamide component,
• wherein a tensile strength of the fishing line is from 7 to 11 cN/dTex,
• wherein a knot strength of the fishing line is from 5 to 10 cN/dTex, and
• wherein the monofilament has an average diameter (Day) of 0.05 to 3.5 mm and a diameter variation (Vd), as defined by the following formula (2), of 6% or less;
• Vd=[(Dmax−Dmin)/Dav]×100(%) (2)
• wherein
• Dmax is the maximum diameter of one monofilament,
• Dmin is the minimum diameter of one monofilament, and
• Dav is the average diameter of one monofilament.
