Abstract
The utility model provides a U type three -layer net, because surface course net and bottom net are U type structure, the longitude and latitude of surface course net is than being 2: 1, the mesh of bottom net is greater than the mesh of surface course net, and the diameter of connection line is lighter than surface course warp and surface course weft's diameter, consequently, the utility model discloses a rate height is kept to U type three -layer net's wet end, and drainage is good, and the paper shaping of producing is effectual, and the wire mark is few to low in production cost.
Description
Technical field
This utility model belongs to pulp technology for making paper, is specifically related to the U-shaped three-layer network of a kind of paper grade (stock).
Background technology
Along with the development of papermaking technology, people are more and more higher to the prescription of paper, and wire-cloth is a big key element of quality and the production cost affecting high-grade special light basis weight thin paper, at present, it is common to use two and half polyester webs are manufactured paper with pulp high-grade special light basis weight thin paper.
But, adopt two and half polyester webs manufacture paper with pulp high-grade special light basis weight thin paper time occur the problem that 1, page wire mark obvious；2, retention is low.Therefore, the paper produced of low quality, and production cost is high.
Summary of the invention
The purpose of this utility model is in that to provide a kind of wet end to have retention height, and wire mark is few, the U-shaped three-layer network that production cost is low.
This utility model provides a kind of U-shaped three-layer network, for paper pulp is manufactured paper with pulp, including: surface layer net, U-shaped, surface layer warp and surface layer parallel weaving form；Underlying network, U-shaped, bottom layer warp yams and bottom parallel weaving form；Joint lines, staggered through between described surface layer net and described underlying network, wherein, the longitude and latitude rate of surface layer warp and surface layer parallel is 2:1, and the mesh of underlying network is more than the mesh of surface layer net.
U-shaped three-layer network of the present utility model can also be further improved restriction: the diameter of bottom layer warp yams and bottom parallel is more than the diameter of surface layer warp and surface layer parallel.
U-shaped three-layer network of the present utility model can also be further improved restriction: the diameter of joint lines is less than the diameter of surface layer warp and surface layer parallel.
U-shaped three-layer network involved by this utility model, because surface layer net and underlying network are U-shape structure, the longitude and latitude of surface layer net is than for 2:1, and the mesh of underlying network is more than the mesh of surface layer net, and the diameter of joint lines is less than the diameter of surface layer warp and surface layer parallel, therefore, the wet end retention of U-shaped three-layer network of the present utility model is high, and drainage is good, the paper good forming effect produced, wire mark is few, and production cost is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of U-shaped three-layer network in embodiment of the present utility model；
Fig. 2 is the close-up schematic view of U-shaped three-layer network in embodiment of the present utility model.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reaching purpose and effect and be easy to understand, U-shaped three-layer network of the present utility model is specifically addressed by following example in conjunction with accompanying drawing.
As it is shown in figure 1, U-shaped three-layer network is for manufacturing paper with pulp to paper pulp.U-shaped three-layer network comprises: surface layer net 110, underlying network 120 and joint lines 130.
Surface layer net 110 is formed by surface layer warp 111 and surface layer parallel 112 weaving, and the ratio of the longitude and latitude between surface layer warp 111 and surface layer parallel 112 is for 2:1, and surface layer net 110 is U-shape structure so that pulp drainage is more easy.
Underlying network 120 is U-shape structure, bottom layer warp yams 121 and bottom parallel 122 weaving form.The mesh of underlying network 120 is more than the mesh of surface layer net 110.In the present embodiment, the mesh of underlying network 120 is the twice of the mesh of surface layer net 110.The diameter of end warp and back weft line is more than the diameter of face warp Yu face picks line so that the wearability of underlying network 120 improves, and solid space volume increases, and longer than the upper wire life-span, drainage performance is good.
As in figure 2 it is shown, joint lines 130 is staggered through between surface layer net 110 and underlying network 120, thus being coupled with underlying network 120 by surface layer net 110, wherein, the diameter of joint lines 130 is less than the diameter of face warp dough-making powder parallel, and therefore, joint lines 130 is not easy to be worn.Joint lines 130 according to the purposes of U-shaped three-layer network with require that consumption is different.
Above-mentioned embodiment is preferred case of the present utility model, is not intended to limit protection domain of the present utility model.
