ABSTRACT:
Improved wear and load-carrying properties result for a resin-impregnated fabric bearing wherein the bearing surface includes, as the most significant fabric component, a yarn which is a compounded bundle of sized TFE filaments and sized filaments of high-temperature nylon, in the proportion of at least no more than 50 percent TFE by volume. The yarn is loosely twisted, to the extent that after construction of a fabric with said yarn, the yarn is fully washable, to remove the sizing, down to the innermost filaments. This enables full impregnation of the fabric with synthetic resin, and curing in substantially intimate and continuous and void-free relation of the resin to all filaments within the yarn of the fabric.
