Abstract

The invention discloses a three-layer paper making forming net with high lateral stiffness, which comprises a surface net and a bottom net that are formed by crosswise weaving warps and wefts, wherein the surface net and the bottom net are connected and compounded by connecting lines; the surface net adopts a two-dimensional plain weaving structure; the bottom net adopts a six-dimensional broken satin weaving structure; the warps comprise surface net warps and bottom net warps; the diameters of the surface net warps and the bottom net warps are respectively 0.18 mm and 0.22 mm; the weaving density of the surface net warps and the bottom net warps is 24 unit / cm; the wefts comprise surface net wefts and bottom net wefts, wherein the surface net wefts comprise surface net nylon wefts and surface net polyester wefts respectively with a diameter of 0.18 mm; and the surface net nylon wefts are used as the connecting lines and connected with the compound surface net and the bottom net in an asymmetric connecting mode. The invention enhances the lateral stiffness of the forming net, strengthens deformation resistant capability in use, and is more suitable for a high-speed paper maker to operate.

Description

technical field

[0001] The invention relates to the technical field of papermaking, in particular to a three-layer papermaking forming wire with high lateral stiffness. Background technique

[0002] At present, the 2B5616 series of wires for making cultural paper with a quantitative weight of 55 g / m2 or more are often used for the surface and bottom wires of cultural paper and stacked paper machines. The warp density of this series of wires is 56 wires / cm Wire diameter 0.17mm, surface weft is eight shed satin weave, one thick (0.18mm polyester) and one thin (0.13mm polyester) weft, bottom weft is equal diameter (0.35mm polyester), (0.35mm nylon) 16-shed satin weave, the weft density can reach up to 60 wires / cm, the mesh structure of this series is stable, the air permeability and fiber retention rate are medium, the forming dehydration is good, and the service life is also good, but because it is two and a half layers Weaving structure, the warp thread intersperses the surf...
