Abstract
A wire fishing line for deep water trolling comprises a length of stainless steel or Monel wire, with a first tough, substantially non-porous Formvar polyvinyl formal polymer coating layer adherently bonded to the peripheral surface of the wire, and a second, low-friction Nylon linear polyamide coating layer bonded to the peripheral surface of the first coating layer, whereby a polymer-coated wire is achieved which has high lubricity, is capable of smooth closely packed coiling in even helical layers on the spool of a fishing reel, and which is substantially impervious to salt water and fresh water immersion and capable of repeated immersions without significant loss of tensile strength.
