Abstract
The utility model relates to a polyester multilayer net for papermaking, which is composed of a top net and a bottom net. The latitude and longitude density of the top net is larger than the latitude and longitude density of the bottom net. The line diameter of the latitude and longitude lines of the top net is smaller than the line diameter of the latitude and longitude lines of the bottom net. The top net adopts the weaving latitude lines of two ling diameters. The top net and the bottom net penetrate and combine to form a whole net by the same weaving longitude line. The utility model has the characteristics of long service life, favorable water filtering performance and low cost, and the utility model solves the defect that the past polyester multilayer net can not be applied on a paper making machine with high speed.
Description
The utility model relates to a kind of paper grade (stock) polyester multilayer net
Existing polyester papermaking wire-cloth is generally the warp that adopts same line footpath, the individual layer net that parallel is made.Because the warp of individual layer net gauge mesh of the same race, the line of parallel are directly fixing, if satisfy the water filtering performance requirement, select for use thin warp, parallel to weave, the papermaking wire-cloth defective that lack service life in high-speed paper machine then appears; In order to satisfy the requirement of papermaking wire-cloth long service life, select for use big line footpath wire rod to weave on the contrary, it is poor then can water filtering performance to occur again, and fiber fines runs off many, influences the problem of the surface quality of paper; In addition, single-layer polyester network interface intensity is on the low side, has also directly influenced the service life of papermaking wire-cloth.So the individual layer net can not fundamentally solve the contradiction of service life and water filtering performance, thereby its Application Areas is restricted widely.
The purpose of this utility model is to provide the paper grade (stock) polyester multilayer that a kind of life-span is long, intensity good, dewatering good, the loss of fiber fines is few net.
The purpose of this utility model is to realize by the technical scheme that is made of top net, spacer screen, the top net through filling density greater than spacer screen through filling density, the top net is weaved parallel and is adopted the line footpath less than the main parallel in spacer screen parallel line footpath and the line footpath additional parallel less than main parallel line footpath, top net weave the warp of weaving that warp also is a spacer screen, weave warp and top net and spacer screen are worn to tie be merged into integral net.
The top net is the major part of dewatering of pulp, and its designing requirement should reduce the loss of paper pulp fiber as best one can, makes whole wire side keep good water permeability again; And spacer screen mainly works the effect of setting off, and also will improve outer force bearing strength as far as possible in addition; Spacer screen causes bad influence with compound the avoiding again of top net as far as possible to the dehydration property of top net simultaneously.Comprehensive these factor the utility model are optimal design like this:
The line of the additional warp of top net directly is 0.10mm-0.15mm.
The line of top host's parallel directly is 0.17mm-0.20mm, and the line of spacer screen parallel is 0.30mm-0.35mm directly, and the line of weaving warp directly is 0.15-0.20mm.
Weave the warp intersection and wear knot top net and spacer screen, weave warp and on spacer screen, adopt the double jump line structure.
Above structure adopts top net and spacer screen stack to be composited with the polyester multilayer net, therefore good effect of the present utility model compared with the prior art is embodied in: first, big online through the top of filling density, additional fine filling line, both can reduce fiber fines and run off, increase of the set off effect of top net, not influence the dehydrating effect of top net again fiber fines, help improving the quality and the class of paper, reduce the environmental pollution of running off and causing because of paper pulp; The second, adopt for a short time through the woven spacer screen in filling density and thick line footpath, wear-resistant, not easy to wear, dehydrating effect is good, long service life; And joint strength is improved, and is useful on the high-speed paper machine and uses, and it is big to produce the paper amount.The 3rd, top net and spacer screen adopt the identical warp of weaving, and weave warp and play again simultaneously the wear tie lines effect of top net with the spacer screen merging, have both reduced material cost, can not make changing through filling density that top net and spacer screen design again.
The utility model is described in further detail in conjunction with the accompanying drawings by the following examples.
The broadwise structural representation that Fig. 1 analyses and observe with warp-wise for embodiment
Shown in Figure 1 is the woven repetitive of reticulate pattern, this polyester multilayer net is to be made of two layers of mesh, be respectively top net 1 and spacer screen 2, top net 1 adopts big footpath filling density to weave, spacer screen 2 is to adopt path filling density and heavy wire to weave, top net 1 and spacer screen 2 adopt the common radial line 3 of weaving, and weave radial line 3 and top net and spacer screen are worn to tie are merged into integral net as wearing tie lines.
The parallel of weaving of top net 1 has two kinds of line footpaths, and main parallel 4 lines directly are 0.18mm, and additional parallel 5 lines directly are 0.12mm; The line of spacer screen parallel 6 is 0.32mm directly, weaves the warp line and directly is 0.17mm.
Weave warp 3 intersections and wear knot top net 1 and spacer screen 2, weave warp 3 and on spacer screen 2, adopt the double jump line structure.
