Abstract
The present invention discloses a warp-self-binding forming net which belongs to the technical field of papermaking forming network, comprising a surface layer, a bottom layer and a connecting line, the surface layer is composed of a plain weave structure in which the surface layer is alternately interwoven with the weft, and a lattice structure which is intertwined with the latitude and the weft, said connecting lines being arranged in pairs, from the warp to the connecting layer and the bottom layer. The invention is that the connecting lines are regularly intertwined in the upper and lower layers of the network, so that the upper and lower layers of the network connected into one, does not produce relative rubbing, sliding, eliminating the internal wear; with dehydration performance, dehydration time is short and has a uniform size, to prevent the three-tier network wear. It also has a longer service life and is easy to flush.
Description
Technical field
The present invention relates to forming net for papermaking technical field, more particularly to a kind of warp bind forming net certainly.
Background technology
The paper making forming net for using at present is formed by polyester, two kinds of yarn woven of nylon, easily receives temperature, humidity, tension force
Impact have contraction, the phenomenon for extending, nylon also has adsorptivity, and polyester do not have adsorptivity.Finished net is using front having contraction
Phenomenon, length can shorten, can be by cutting out the control of net length.Extension phenomenon is had during use, exceeds paper when extending excessive
Machine range of accommodation can cause net cannot tensioning on paper machine, not reaching should be tensioned, it is impossible to use, more because extend reduce net
The performance and used life of itself.
And immediate with the technology of the present invention be that parallel is connected SSB three-layer network.Parallel connection SSB three-layer network is using laterally double
Parallel sewing system, referred to as from suturing, the nylon suture rotation that two are adjoined and is interweaved in surface layer and bottom.From surface layer
See and seem only one line, such surface layer braiding structure is just similar to optimal plain weave, makes surface layer planarization reach optimum
Change.This more effective associated methods, stitching thread not only acts as the effect of suture surface layer and bottom, also functions to support the work of fiber
With.It is advantageous in that and increased fiber support degree and make net tightr on the whole.Because limiting the phase of surface layer and bottom
To motion, inter deterioration is reduced, but is not thoroughly eliminated.As net is during high-speed cruising, be subject to is longitudinal direction
Tension force, such surface layer and bottom will produce relative motion, and along with raw material has extension phenomenon, structure becomes by closely
Loose, surface layer is become much larger with bottom relative motion, so as to produce inter deterioration.This relative motion, can destroy for a long time
Internal structure between stitching thread and surface layer and bottom, the relative geometry of net and warp, the accumulation situation of parallel are all sent out
Change is given birth to, have impact on the dewatering of net.Therefore, with the increase of net run time on paper machine, the later stage occurs
Net deformation, the problem of layering.
Warp connection SSB three-layer network is used as three-layer network of new generation, and the difference being connected with parallel between SSB three-layer network is connection
The connected mode of line is different, connecting material difference.Warp connection SSB three-layer network is using warp (polyester) as connecting line, parallel
Connection SSB three-layer network is using parallel as connecting line, although only distinct in connected mode and connecting material between the two,
But the superiority for having parallel connection SSB three-layer network incomparable.
Content of the invention
The invention provides a kind of warp is from forming net is bound, existing parallel connection SSB three-layer network is solved due to operation
The forming net that the increase later stage of time occurs deforms, the problem of layering.
For solving above-mentioned technical problem, the technical solution used in the present invention is：
A kind of warp is from forming net is bound, and including surface layer, bottom and connecting line, the surface layer is alternately handed over by face warp and face picks
The plain weave structure that knits, the satin construction that the bottom is alternately interweaved by bottom warp and back weft, the connecting line is arranged in pairs, from warp-wise
Connection surface layer and bottom.
Wherein it is preferred to, the quantity of the connecting line is face warp and bottom through sum 1/2.
Wherein it is preferred to, the connecting line is with face warp or the bottom through spaced.
Wherein it is preferred to, the connecting line is polyester warp.
Wherein it is preferred to, the face warp and bottom are through being polyester warp, and the face picks and back weft are polyester or nylon parallel.
Wherein it is preferred to, the face picks is 3 with the ratio of the back weft：2.
Beneficial effects of the present invention：
1. the warp of the present invention is that connecting line regularly interweaves in upper and lower two layers of mesh from forming net is bound, and makes up and down
Two layers of mesh links into an integrated entity, and does not produce relative rubbing, sliding, eliminates inter deterioration；Made using the stretching of tension force on paper machine whole
The structure of individual net is even closer, increased the intensity of net.
2. the warp connecting line of the present invention is changed into polyester from original nylon, and polyester does not have adsorptivity, easily rinses, and reduces
Internal paper pulp accumulation so that its drainability keeps stable, under paper machine longitudinal tension force so that whole warp connection SSB three-layer network
Structure is even closer, increases net intensity, so as to reduce inter deterioration, deformation, lamination.
3. the present invention adopts warp suturing skill, and net water filtering performance remains stable, client during production,
The aspiration of vacuum tank will not be increased as drainage reduces or run slowly and cause the net very fast and production efficiency of abrasion to decline
Deng.Warp connection SSB three-layer network preferably solves paper machine and extends in use and causes drainage decline, quick abrasion, layering
Etc. phenomenon.
4. from binding shaping net, the warp of the present invention has that dewatering is stable, dewatering time is short, mesh is uniform in size, anti-
Only three-layer network inter deterioration, life-span are more permanent and rinse easy advantage.
