Abstract

PURPOSE:To obtain a fishing line capable of slowly lowering the strength by change with the lapse of days, decomposed over a long period, excellent in wetting property and having good sinking property and capable of sharply reacting with fish's bite. CONSTITUTION:A polyester-based monofilament is formed into a string and the string is immersed in a solution containing an unsaturated compound having hydrophilic group, e.g. acrylic acid or methacrylic acid, a swelling agent such as monochlorobenzene, a polymerization inhibitor and a phosphoric acid ester- based nonionic surfactant and temperature of the solution is gradually raised from ordinary temperature and the string is subjected to heat treatment at 100 deg.C for 60min in order to carry out graft polymerization to provide the objective fishing line. This fishing line has 2X10<-4> to 6X10<-3>gmol/g line amount of hydrophilic group such as carboxyl group and has unsaturated compound having hydrophilic group which was subjected to graft polymerization and slowly causes lowering of strength by change with the lapse of days and is decomposed over a long period and excellent in wetting property to water and capable of sharply reacting with fish's bite, because fishing line has good sinking property also as the main line.
