The shaping net for papermaking adopts the unique design of two-layer net to solve the contradictionbetween the paper formation and the abrasion, so that the surface of the formed paper has good planeness, the paper is free from wire mars, the structure stability is good, the stiffness is high, theabrasion resistance is good, the service life is long, the production cost of papermaking factory is reduced, and the economic benefit of the papermaking factory is improved.
Description
Technical field
The utility model belongs to the forming net for papermaking technical field, more particularly, relates to a kind of forming net for papermaking of novel tied double weave.
Background technology
At present, forming net for papermaking is the essential valuable dehydration equipment of papermaking enterprise, be to be applied in the paper machine wet end, with certain speed round and round, paper pulp evenly is ejected on the forming net by head box, operation by forming net is through dewatering elements such as breast roll, forming board, Wiper blade, low vacuum suction box, high vacuum suction box, couch rolls, the moisture removal in the slurry is retained in fiber and filler form the l Water Paper page or leaf on the forming net and be sent to press section.The use of forming net must be satisfied quality of finished paper and requirement in service life, therefore in the design of forming net institutional framework, must take all factors into consideration the fiber support index, air permeability, freeness of forming net, in length and breadth to factors such as stability, deflection and service lifes, make it reach optimization.
Development and technological progress along with China's paper industry, novel papermaking dehydration equipment polyester webs used and the replacement copper mesh from the eighties in 20th century, improved the service life of papermaking wire-cloth greatly, but along with the development and the paper quality of paper industry requires more and more higher, the individual layer forming net is if adopt thin graticule footpath, in length and breadth to poor stability, deflection is little, service life is short, if adopt thick graticule footpath, fiber support index is little, retention is low, wire mark is heavy, and individual layer forming net joint strength is low simultaneously, can't satisfy the instructions for use of high speed paper machine, therefore the individual layer forming net can not fundamentally solve the contradiction in quality of finished paper and service life, thereby its Application Areas is restricted greatly, and use amount reduces significantly, only is applied at present on the low and toilet paper machine of paper quality requirement.
In order to solve the contradiction in individual layer forming net quality of finished paper and service life, in the prior art, designed a kind of paper grade (stock) multi-ply forming fabric as Chinese patent 99241818.8 " paper grade (stock) polyester multilayer net ", it is made of top net, spacer screen, top net filling density is greater than the spacer screen filling density, net parallel line footpath, top is less than spacer screen parallel line footpath, and the top net adopts two kinds of parallel lines directly to weave, and the top net is worn knot with spacer screen by identical warp and is merged into integral net.Have characteristics such as long service life, quality of finished paper is good, cost is low, solved the individual layer forming net and can not be applied in defective on the high speed paper machine.This forming net is interwoven by system's warp and two system's parallels, is called filling-backed weave, but its institutional framework design does not fundamentally solve into the contradiction between paper and the wearing and tearing.In order fundamentally to solve into the contradiction between paper and the wearing and tearing, in the prior art, designed a kind of polyester multilayer composite web as Chinese patent 200520075541 " a kind of polyester multilayer composite web ", be made up of top net, spacer screen, compound from connecting between top net and the spacer screen, the graticule line footpath of top net is less than the graticule line footpath of spacer screen, the top net adopts the plain weave reticulate pattern, spacer screen adopts 5 to combine satin weave, and top net and spacer screen warp-wise are 1: 1 structure, and broadwise is 2: 1 structures.Net parallel in top is split into two parallels by texture connect top net and spacer screen, top net and spacer screen are composited through the texture braiding.Because adopt such structure, the paper quality of producing is good; Reduced environmental pollution; Reduce production cost, improved production efficiency.This patent adopts 20 heald frame looms to weave, and the top net adopts the plain weave reticulate pattern, and spacer screen adopts 5 to combine satin weave, it is more to interweave between the graticule, and flexibility is bigger, is unfavorable for weaving, the floating long line of back weft parallel is shorter, is unfavorable for improving the line footpath of parallel, and then the service life of improving forming net.
