Abstract
Abstract A novel open weave endless dryer belt is disclosed which comprises in a leno weave, warp yarns of synthetic organic fibers and crosswise yarns of synthetic organic fibers braided over a core of glass fibers and/or metal wire. The fabric weave is then finished with a coating of a temperature resistant resin. The fabric of the invention is useful for fabricating conveyor belts employed in conveying textiles through dryers and in like applications.
