Embodiment shall fall in the protection scope of this application.
In recent years due to Market competition, energy cost is improved, and domestic some large-scale paper plants are selecting new papermaking raw
Tend to high speed, efficient paper machine when producing line.Currently, the max. speed of paper machine is up to 2500m/min.And existing three layers
Forming net generally using laterally suture (i.e. articulamentum using pairs of weft connection paper forming layer and machine level), three-layer forming net at
Paper layer and machine level are easy to produce relative displacement on high-speed paper machine, to cause accelerated wear test inside forming net, and then reduce
The service life of forming net.
Referring to Fig. 1, Fig. 1 is the structural schematic diagram of one embodiment of the application speciality paper paper making forming net.The application
Provided paper making forming net 1 is three-layer network, including paper forming layer 10, articulamentum 12 and machine level 14, and articulamentum 12 includes first
Connection warp 120 and the second connection warp 122 are respectively used to connection paper forming layer 10 and machine level 14.In the present embodiment, it shapes
Net 1, which is interweaved monofilament polyester or nylon monofilament by 50 heald frames, to be formed, and forming net 1 includes multiple minimum organizational units, most group
Knit the warp of weft and 36 monofilament polyesters composition that unit includes 50 monofilament polyesters or nylon monofilament composition, above-mentioned articulamentum
12 the first connection warp 120 and the second connection warp 122 connection paper forming layer 10 and machine level 14, due to longitudinally being connected using warp
It is connected into paper layer 10 and machine level 14, so that the paper forming layer 10 and machine of high-speed paper machine provided herein speciality paper forming net 1
Device layer 14 is not likely to produce relative displacement on high-speed paper machine, and then slows down the abrasion inside forming net 1, extends making for forming net 1
Use the service life.
In an application scenarios, above-mentioned warp includes the warp 102 of paper forming layer 10 and the warp 142 of machine level 14, latitude
Line includes the weft 100 of paper forming layer 10 and the weft 140 of machine level 14.In another application scenarios, the weft of paper forming layer 10
100 are used alternatingly one using the weft 100 of the wefts being made of entirely monofilament polyester or paper forming layer 10 is made of monofilament polyester
Weft and a weft being made of nylon monofilament.In another application scenarios, the weft 140 of machine level 14 uses Quan Youju
The weft of ester monofilament composition or the weft 140 of machine level 14 be used alternatingly the weft that one is made of monofilament polyester and one by
The weft of nylon monofilament composition.
In one embodiment, please continue to refer to Fig. 1, paper forming layer 10 by warp (that is, warp 102 of paper forming layer 10) and
Weft (that is, weft 100 of paper forming layer 10) is knitted to form by 1/1 plain weave weave；Specifically, the warp of 1/1 plain weave braiding
Interweaved with weft with rule one on the other, i.e., latitude and longitude are just staggeredly primary every single line, and intertwined point is more, and latitude and longitude are bent
Song point at most so that 10 fiber support index of paper forming layer is higher, mesh uniformly, it is smooth, improve finished paper fiber and
The retention of filler, it is ensured that paper sheet formation is uniform, and it is convenient that page is removed from forming net, more smooth at paper surface.Certainly, at it
