ABSTRACT:
A polymeric yarn to be coated with electroless nickel is pretreated with an acid and a surfactant to render the yarn surfaces water wettable and not substantially mechanically degraded. All surfaces of yarn formed of polymeric monofilament fibers are coated with a layer of electroless nickel which can also include an electrolytic metal such as copper on the nickel. The yarn is passed through an electroless Ni aqueous bath under little or no tension so that the electroless Ni can coat all of the monofilament surface substantially uniformly. The nickel coated yarn then can be coated with electrolytic metal such as copper in an electrolytic metal plating step.
