<p>A hydrophobic polymer (50) is adhesively coated on the surfaces of the wound string (10) within its interstitial voids (20), while the exterior surfaces (36) remain uncoated. The polymer is applied by soaking the string in a liquid polymeric solution to flow the solution into the interstitial voids. The string is removed from the bath and the residual solution is removed from the exterior surface of the string using a resilient scraper. The string is hung to dry for 8 hours in a clean room environment at ambient temperatures and, more preferably, maintained at a temperature of between 20° C and 25° C. Alternatively, the string is treated by a combination of heat and drying.</p> |
