    摘要： A resin-impregnated endless belt for a long nip press or calender of the shoe type, or for other papermaking and paper-processing applications, has a base support structure which includes coated elements, such as yarns, having a coating of a first polymeric resin material. The base support structure is in the form of an endless loop, at least one of the inner and outer surfaces of which is coated with a second polymeric resin material. The second polymeric resin material impregnates the structure of the base support structure, rendering it impermeable to oil and water. The first and second polymeric resin materials have an affinity for one another, so that the coating of second polymeric resin material on the base support structure as a whole establishes a chemical, as well as a mechanical, interlock with the coated yarns having the coating of first polymeric resin material.

    摘要： A needled press felt, i.e. a felt which is intended to be used in the press section of a papermaking machine. The batt part of the felt comprises at least two kinds of fiber one of which consists of fibers having a diameter size 0.010 mm or less. These fibers are removed either successively or intermittently during the service of the felt in the press section, whereas the rest of the fibers in the batt part of the felt, i.e. the fibers having a larger diameter than those of the first kind, remain in the batt part.

    摘要： 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.

    摘要翻译： 用于造纸机的长辊隙压榨带具有用聚合物树脂材料浸渍并涂覆在至少一侧的纺织品基材。 聚合物树脂材料在固化后研磨和抛光，为带提供光滑表面和均匀的厚度。 纺织基材包括具有多个叶片的非圆形横截面的纺织部件（单丝，连续细丝或短纤维）。 这种横截面为纺织部件提供比由具有圆形横截面的相等的部件提供的更大的表面积。 结果，增强了聚合物树脂涂层与织物基材的机械互锁和化学键合或粘附。 此外，具有多个叶片的具有非圆形横截面的织物部件降低了纺织品基材的渗透性，从而可以防止施加到一侧的聚合树脂材料流过另一侧。
