Abstract

The invention discloses a high-wear-resistance high-fiber three-layer papermaking forming net and papermaking equipment. The high-wear-resistance high-fiber three-layer papermaking forming net comprises a paper forming layer, a connecting layer and a machine layer. The paper forming layer is formed by weaving paper forming layer warp yarns and paper forming layer weft yarns in a staggered mode, and the machine layer is formed by weaving machine layer warp yarns and machine layer weft yarns in a staggered mode, wherein the number ratio of the paper forming layer warp yarns to the machine layerwarp yarns is greater than or equal to 1.6. By means of the mode, the retention rate of fibers and filler can be increased while the abrasion resistance of the machine layer in the high-abrasion-resistance high-fiber three-layer papermaking forming net is guaranteed.

Description

technical field [0001] The application relates to the technical field of papermaking, in particular to a high wear-resistant and high-fiber three-layer papermaking forming wire and papermaking equipment. Background technique [0002] The papermaking forming wire is an important forming and dewatering equipment in the wet end of the paper machine. The existing forming wire generally includes a three-layer structure consisting of a paper layer, a machine layer and a connecting layer from top to bottom. The three-layer forming wire of this structure can be Applied to general paper machines to complete the requirements of paper sheet forming and dehydration tasks. At present, the common SSB three-layer forming fabric cannot improve the retention rate of fibers and fillers while ensuring the wear resistance of the machine layer. Contents of the invention [0003] The main purpose of this application is to provide a high wear-resistant and high-fiber three-layer papermaking for...
