Abstract
The utility model relates to a wear-resistant and pressure-resistant high-speed papermaking felt which comprises a felt body, the felt body comprises a surface fiber layer, an inner fiber layer, a bottom fiber layer and a yarn weaving combination layer, and the yarn weaving combination layer is formed by weaving upper-layer warp yarn, upper-layer weft yarn, lower-layer warp yarn and lower-layer weft yarn. The lower-layer warp yarns and the lower-layer weft yarns are woven in a crossed manner and are connected with the bottom-layer fiber layer in a penetrating manner; and the upper-layer warp yarns and the upper-layer weft yarns are woven in a crossed manner and are connected with the lower-layer warp yarns and the lower-layer weft yarns in a woven manner. The warp yarns of the upper base cloth and the lower base cloth are alternately configured by the plied yarns and the monofilaments, and the upper yarns and the lower yarns are not parallel and form a certain included angle, so that the pressure resistance of the blanket is improved, the entanglement binding force between fibers and the base cloth is improved, the blanket is not prone to hair falling in the use process, the wear resistance of the blanket is improved, and the service life is prolonged.
