Abstract
A long nip press belt for a papermaking machine has a textile substrate impregnated and coated on at least one side with a polymeric resin material. The polymeric resin material is ground and buffed after being cured to provide the belt with a smooth surface and a uniform thickness. The textile substrate includes textile components (monofilaments, continuous fine filaments or staple fibers) having non-circular cross sections with a plurality of lobes. Such cross sections provide the textile components with a greater surface area than would be provided by components of equal denier having circular cross sections. As a consequence, the mechanical interlock and chemical bond or adhesion of the polymeric resin coating to the textile substrate are strengthened. In addition, the textile components having non-circular cross-sections with a plurality of lobes reduce the permeability of the textile substrate, so that polymeric resin material applied to one side may be prevented from flowing through to the other side.
