High-speed wide 16-heald mesh-mark-free three-layer paper making mesh

Abstract

The invention discloses a high-speed wide 16-heald mesh-mark-free three-layer paper making mesh. The high-speed wide 16-heald mesh-mark-free three-layer paper making mesh is integrated composite intertexture which is formed by interweaving polyester or nylon monofilaments through 16 heald frames, and the high-speed wide 16-heald mesh-mark-free three-layer paper making mesh comprises the three different woven structures of a finished paper layer, a middle connecting layer and a machine layer. A 1/1 plain weaving method is adopted by the finished paper layer, an eight-heald weaving method is adopted by the machine layer, the middle connecting layer comprises a pair of connecting weft yarns, and the finished paper layer and the machine layer are connected. Due to the fact that the 1/1 plain weaving method is adopted by the finished paper layer, the fiber supporting index is improved, meshes are even and smooth, the fiber and packing retention of paper is improved, paper forming is even, the paper can be separated from the mesh easily, and the finished paper is smoother. The connecting weft yarns are used for being connected with the two layers, and the upper layer and the lower layer are combined more firmly. The eight-heald weaving method is adopted by the machine layer, the span of the weft yarns of the machine layer is increased, the abrasion resistance of the forming mesh is improved, and the service life is longer.

Description

Technical field [0001] The wet part of the invention involves the papermaker. Specifically, it is a kind of line network equipment that is applied to the wet part of the papermaker. Background technique [0002] Paper forming net is an important forming and dehydration material for the wet part of the papermaker. Although the existing paper formation network can basically complete the forming and dehydration tasks of paper pages, its deficiencies are the existing paper forming net into the paper layer and unevenness.The fiber support index is not high, resulting in obvious surface marks on the surface of the paper, making the fiber and filler of paper not high, the paper pages are not uniform, the paper pages are not easy to peel from the Internet, and it is not suitable for the need to produce high -end paper.In addition, the existing paper formation network is weakly combined with the combination of the machine layer, which is easy to produce inter -layer separation and relativ...

[0002] Papermaking forming wire is an important forming and dewatering material in the wet end of a paper machine. Although the existing papermaking forming wire can basically complete the task of paper sheet forming and dewatering, its disadvantage is that the surface layer of the existing papermaking forming wire is uneven. , The fiber support index is not high, resulting in obvious net marks on the surface of the paper, the retention rate of paper fibers and fillers is not high, the paper sheet is unevenly formed, and the paper sheet is not easy to peel off from the net, which is not suitable for the production of high-grade paper.

Moreover, the binding force between the paper forming layer and the machine layer of the existing papermaking forming wire is weak, and separation and relative displacement between layers are easy to occur, and the wear resistance of the contact surface between the machine layer and the paper machine is not enough, resulting in a short service life of the papermaking forming wire

CN2923792Y discloses a three-layer forming net of strong fiber dual-function weft polyester. The forming net adopts 16 sheds weaving. The connection between the paper layer and the machine layer is still not stable enough, the diameter of the warp and weft used in the paper layer is relatively thick, paper marks will still be left on the paper, and the wear resistance of the machine layer is not enough
