Method for manufacturing forming fabric for warp connection paper making

Abstract

The invention discloses a method for manufacturing forming fabric for warp connection paper making. The manufacturing process of the forming fabric comprises the following steps of filament detection, beaming, mesh weaving, mesh inspection, primary sizing, mesh cutting, insertion, secondary sizing, finished-product inspection, packaging and storage. When a mesh is weaved, three system warps and two system wefts are interwoven, wherein independent let-off of the three system warps is conducted through three let-off shaft systems. Tension of the three system warps is controlled by three corresponding let-off shaft systems, so that a surface layer mesh is firmly connected with a bottom layer mesh, combination compactness is good, a single filament in a mesh body has no inner friction, and the layering problem in the use process of the forming fabric is solved. A first system warp and a third system connection warp interweave with a first system weft to form the surface layer mesh for supporting paper sheet fibers, surface evenness is good, and a paper sheet has not filament marks. A second system warp and a third system connection warp interweave with a second system weft to form the bottom layer mesh for being resistant to abrasion of a paper machine. Abrasion-resistant performance is good, and a service life is long.

Description

technical field [0001] The invention relates to a forming wire for papermaking, in particular to a method for manufacturing a forming wire for papermaking connected by wires, which is applied in the wet part of a paper machine to remove moisture from the slurry and retain fibers and fillers on the forming wire to form a wet paper sheet , sent to the press section. Background technique [0002] The forming wire for papermaking is an essential and valuable dehydration equipment for papermaking enterprises. It is applied in the wet part of the paper machine and runs circularly at a certain speed. Board, wiper, low vacuum suction box, high vacuum suction box, couch roll and other dewatering components; remove the moisture in the slurry, keep the fiber and filler on the forming wire to form a wet sheet, and send it to the press section. The use of the forming wire must meet the requirements of paper quality and service life. Therefore, the fiber support index, air permeability, ...

Problems solved by technology

[0006] The manufacturing process of the forming fabric for papermaking is: wire inspection—warping—weaving—mesh inspection—primary shaping—cutting—inserting—secondary shaping—finished product inspection—packing and warehousing; , can solve the defects of polyester multi-layer nets for papermaking, but its disadvantages are that the warps of the three systems have different tensions during weaving, and the use of two warp beam systems leads to poor flatness of the forming net surface and wear resistance of the bottom net At the same time, the tightness of the combination of the upper and lower layers of the net is not enough, it is prone to delamination during use, and the vertical and horizontal stability is poor, especially on the high-speed paper machine. It will not only affect the paper surface Smoothness, affecting paper quality, and not suitable for high-speed paper machines
