ANTIFOULING PROCESS FOR FISHING NET

PURPOSE:To prevent the adhesion of marine life to a fishing net by producing a net with a blended yarn of copper and synthetic fiber and applying electric potential to the net. CONSTITUTION:A yarn is produced by blending a thin wire 2 of copper or a copper alloy with a nylon yarn 1 which is a kind of synthetic fiber. A fishing net 7 is produced by using said blended yarn. A battery 5 is connected to the net and an end of fishing net is used as an anode. A counter electrode 4 is placed in the fishing net. The applied electric potential is preferably 1-2V. Hydrogen ion is generated on the anode by the application of electric potential and the ion dissolves an insoluble oxide film of copper to expose the metal surface. Copper ion is dissolved in sea water to keep the antifouling effect over a long period.
