Abstract

The utility model relates to a multilayer longitude and latitude interweaved strong basal cloth paper making blanket, which is characterized in that the basal cloth layer is a whole thickening and fortified strong textile is interweaved by at least three layers of longitude and latitude, prickling flockers on the upper and under surfaces are respectively embedded two layers of special paper making blanket Kapron coarse staple fiber layer with different fiber diameters, another special paper making blanket thin staple fiber layer is embedded into the upper surface as a paper holding working surface. The utility model has the advantages of high intensity, good recovery, strong vacuum dewatering ability and perfect surface performance. The blanket has the thickness of 4.17mm, a meridional breaking strength of 6925.6 N/5cm, a ventilation property of above 400mm/s, and the adapting paper locomotive has a speed of 700 to 1000 meters per minute, which can satisfy the requirements of high speed, high line pressure and strong breaking strength of papermaking industry.

Description

The multilayer longitude and latitude powerful base cloth felt that interweaves

Affiliated technical field

The utility model relates to that a kind of paper machine of making continuous webs of paper transmits and the woollen blanket of squeezing paper web, specifically is a kind of multilayer longitude and latitude powerful base cloth felt that interweaves.

Background technology

China's felt has general woolen blanket, spacer screen woollen blanket and combination felt three classes at present.General woolen blanket is made warp with cord fabric thread, and is cheap, but woollen blanket poor dimensional stability, easily constriction, pleating, powerful low.Single, double layer spacer screen woollen blanket intensity increases, but still can not satisfy the needs of 500 meters/minute high line pressures of above high speed paper machine high speed.Combination felt (1+X woollen blanket) flatness is better, separate base cloth is parallel is combined into but its base cloth layer is by two layers or multilayer, layer does not have parallel with interlayer and links, only depend on the cohesive force of aspect part staple fibre bonding, make between layer and the layer adhesion very weak, use the time very easily lamination occurs and influences service life of woollen blanket on high speed paper machine.So the high speed paper machine that present China produces high-grade paper is with the basic dependence on import of woollen blanket.

Summary of the invention

In order to overcome existing low, the easy layering of felt brute force, pleating etc. deficiency, the utility model provides a kind of multilayer longitude and latitude powerful base cloth felt that interweaves, make that its fracture strength height, recovery are good, phozy, good permeability, adapt at a high speed, the needs of high line pressure paper machine.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of multilayer longitude and latitude interweaves powerful base cloth felt from top to bottom successively by the band ply of paper, the crude fibre layer, compositions such as base cloth layer and crude fibre layer, it is characterized in that base cloth layer is woven into the thickening of an integral body by warp and parallel more than three layers or three layers, the powerful tissue layer of strengthening constitutes, descend the two sides on the needled flocking machine, to implant the special-purpose polyamide fibre coarse staple fibre of the felt layer of two-layer different fibre diameters respectively thereon, on its upper space one deck, replant into the thin short fiber layers of the special-purpose polyamide fibre of one deck felt as band paper working face.

The utility model is owing to adopted more than three layers warp and latitude to knit to be woven into that to thicken strengthened powerful base cloth layer be base cloth, and the woollen blanket recovery of making is good, intensity is high, the vacuum dehydration ability is strong, and surface property is outstanding.Detect through Jiangsu Province Bureau of Technical Supervision fiber and quality test of textile product station, the warp-wise fracture strength reaches 6925.6N/5cm, with warp be two-layer woollen blanket mutually specific strength improved 75%, the thick 4.17mm of woollen blanket, more than Air permenbility 400 mm/second, its good effect is the needs that can satisfy paper industry requirement high speed, high line pressure, high fracture strength fully, adapts to paper machine speed and reaches 700～1000 meters/minute, fully can import substitutes.

Description of drawings

Fig. 1 is each layer of the utility model structural representation.

Fig. 2 is the local enlarged diagram of the base cloth layer graticule institutional framework among Fig. 1.

Among the figure: 1. be with paper fine fiber layer, 2. crude fibre layer, 3. base cloth layer.

The specific embodiment

In Fig. 1, base cloth layer of the present utility model (3), descend thereon on the two sides respectively and implant the special-purpose polyamide fibre coarse staple fibre layer (2) of two-layer felt through the needled flocking machine, in the above one deck crude fibre layer (2) above replant into the special-purpose thin short fiber layers of polyamide fibre of one deck felt (1) as band paper working face.

In Fig. 2, Fig. 2 is the cross section graticule institutional framework partial enlarged drawing of base cloth layer of the present utility model (3).Circle is represented warp among the figure, and curve is represented parallel, and circle internal symbol ABCD......L is one group of three layers of warp organization unit numbering among the figure, and numbering UVWXYZ is one group of parallel element number on the curve.The general fabrics warp has only two-layer, and Fig. 2 is multilayer longitude and latitude that a kind of three layers of warp and parallel the interweave powerful base cloth that interweaves.When for example inweaving parallel U, the loom shedding mechanism will rise up through warp DGHJ, all the other warp ABCEFIKL are in the parallel below, when inweaving parallel VWXYZ equally by this rule.As can be known from Fig. 2, three layers warp is regular by parallel respectively, weave in becomes as a whole equably, has guaranteed this multilayer longitude and latitude the interweave uniformity and the stability of powerful base cloth.Analogize by this rule equally, also can realize with the upper warp and woof base cloth that interweaves if knit four layers, five layers.

Claims

1, a kind of multilayer longitude and latitude interweaves powerful base cloth felt by the band ply of paper, compositions such as crude fibre layer and base cloth layer, it is characterized in that each level is followed successively by the band ply of paper from top to bottom, the crude fibre layer, base cloth layer and crude fibre layer, base cloth layer is the powerful tissue layer that is woven into the thickening reinforcement of an integral body by warp and parallel more than three layers or three layers, descend the two sides on the needled flocking machine, to implant the special-purpose polyamide fibre coarse staple fibre of the felt layer of two-layer different fibre diameters respectively thereon, replant into the thin short fiber layers of the special-purpose polyamide fibre of one deck felt as band paper working face in its upper space.
