ABSTRACT:
A portion of the exterior surface material of a knee-elbow protective guard is covered with a treatment mix comprising 4 parts of a polytetrafluorethylene/resin dispersion, one part of an acrylic polymer resin and 5% of a solution of ammonium sulfate. The treatment mix is then applied to the exterior surface material by a silk screening process, and cured by application of heat so that it bonds to the fibers of the exterior surface material of the guard. The treated portion of the resulting protective guard has a substantially lower coefficient of friction than the exterior surface material of an untreated protective guard.
