Description
Invention field
The present invention relates to papermaking fabric, just usually said forming net for making paper.
Background technology
At paper industry, by a series of equipment and operation paper pulp is become paper, wherein fourdrinier machine is the capital equipment of paper industry enterprise, in the fourdrinier machine paper-making process, paper pulp is transported to head box, and be ejected on the moulding wire side by head box, forming web is to weave the annular guipure for no reason that forms by macromolecular material, on paper machine, forming web is at breast roll, couch roll, drive the net roller, between a plurality of deflector rolls such as wite roll with certain speed round and round, various dewater units on the forming table are positioned at the downside of forming web contact bottom layer, such as suction box, Wiper blade, paper pulp is injected into the one-tenth paper layer of moulding guipure, in the guipure running, the moisture in the paper pulp and other liquid are filtered, and the raw fiber in the paper pulp is separated from aqueous medium, one-tenth paper layer at forming web forms wet web, and enters pressed zone by transfer device after suction couch roll.
Wet web enters pressed zone after leaving the district that is shaped, in pressed zone another kind of papermaking fabric is arranged, we are referred to as " press felt ", press felt is the endless fabric, press felt is between one or more groups pressure roller, with certain speed round and round, remove redundant moisture in the wet web from the pressure of pressure roller, and strengthen removal ability redundant moisture in the wet web by press felt.
Wet web is transported to dry section by after the pressed zone, further removes moisture in the paper web at dry section, with processing and the packing instructions that reach later process.
Produce paper grade (stock) annular fabric for no reason, two kinds of weaving method are generally arranged, a kind of is to weave the warp of usefulness and the yarn of the paper machine operation direction (MD) when using on paper machine is consistent, the yarn of the vertical paper machine operation direction (CMD) when weaving the parallel of usefulness and using on paper machine is consistent, just flat weaving method is weaved, the joint operation of all having known by industry those of ordinary skill becomes the sheet guipure into the endless guipure again.Another kind method is directly to be woven into continuous endless guipure by weaving method for no reason, the yarn of the vertical paper machine operation direction (CMD) when weaving the warp of usefulness and using on paper machine is consistent, and the yarn of the paper machine operation direction (MD) when weaving the parallel of usefulness and using on paper machine is consistent.Above-mentioned two kinds of methods industry again are known, and fabric involved in the present invention is meant the papermaking fabric that above-mentioned any method is produced.
In this patent is described, adopt textile industry and the general versatility term of paper industry, be explained as follows:
MD: the traffic direction of paper machine also is the traffic direction of fabric on the paper machine.
CMD: the traffic direction of paper machine vertical laterally, also be the vertical direction of the traffic direction of fabric on the paper machine.
Warp: on the paper machine traffic direction, promptly the MD direction constitutes the yarn of forming web vertical structure.
Parallel: on vertical paper machine traffic direction, promptly the CMD direction constitutes the yarn of forming web transversary.
Become the paper layer: the forming web on paper machine can be sandwich construction, contacts with paper pulp, and the paper fiber is played the surface layer of direct supporting role.
Contact bottom layer: the forming web on paper machine can be sandwich construction, the bottom that contacts with the dewatering elements of paper machine moulding wet end.
In this specification, become paper layer warp to be called for short the face warp; Become paper layer parallel to be called for short face picks; The contact bottom layer warp is called for short end warp; The contact bottom layer parallel is called for short back weft.
Riser: when warp intersected with parallel, warp was above parallel.
The latitude floating-point: when warp intersected with parallel, warp was below parallel.
Fly number: in the textile industry, the dislocation quantity of identical adjoining two yarns of the crooked rule of fabric, equidirectional successively dislocation.
In the paper process, generally use into the tiny and uniform forming web of paper layer mesh, improve into the enabling capabilities of paper layer to paper pulp fiber, to guarantee the dewatering of forming web simultaneously, to reduce the thickness of forming web simultaneously in the abrasive resistance that increases contact bottom layer, thin thickness not only can improve the dewatering of net, also the energy consumption that reduces paper machine is had positive effect.
The life-span that forming web moves on paper machine is an important indicator of weighing the forming web quality; long service life can reduce the efficient that improves paper downtime of paper machine; and the service life of forming web is decided by the abrasive resistance of the contact bottom layer of forming web; this and the diameter of back weft and the single bending length of back weft have direct relation again; contact bottom layer and the Wiper blade of paper machine and the service life that the lower coefficient of friction between the suction flat box panel can ensure the length of net of while forming web; but bigger back weft diameter and the long single bending length of back weft can cause contact bottom layer and the Wiper blade of paper machine and the bigger coefficient of friction between the suction flat box panel of forming web again, and the structure of forming web is in the past having problem to be solved aspect this contradiction.
Two layers of half-formed net have for example been designed, the disclosed two layers of half-formed net of ZL01804768.8 and US5421375, adopt on five/one on the other interleaving mode once at contact bottom layer warp and back weft, two adjacent latitude floating-points on the same foundation latitude by a foundation through separating, the unit bending length of every foundation latitude has the space of the shared CMD direction of 5 warps, such bending length is not enough, can produce adverse influence to the life-span of forming web; The disclosed two layers of half-formed net of ZL00817083.5, once interleaving mode on contact bottom layer warp and back weft adopt on nine/five once, the unit bending length of every foundation latitude has the space of the shared CMD direction of 13 warps, bending length is enough but increased the coefficient of friction of contact bottom layer, thereby also can produce adverse influence to the life-span of forming web, the contact bottom layer parallel of forming web is than long single bending length on the other hand, increased the bad thickness of forming web, this will increase the energy consumption of paper machine.
In order to address the above problem the performance that improves forming web, prior art such as ZL02141980.9, ZL97182245.2 disclose three formable layer nets, make the one-tenth paper layer of forming web have tiny mesh, thin thickness has for example been designed such forming web, and this forming web adopts one to form paper layer warp, one forms paper layer parallel, one set of contact bottom warp, a set of contact bottom parallel, and many at the stitching yarns that becomes paper layer and contact bottom layer to interweave.Becoming paper layer warp is different with the diameter of contact bottom layer warp, in a same warping, can be woven into the three-layer paper making fabric that paper layer warp separates with the contact bottom layer warp, but can not be woven into two-layer or two-layer half papermaking fabric that paper layer warp and contact bottom layer warp become one group of warp, on the production equipment of same quantity, can not provide a greater variety of products like this to satisfy the demand of how different paper mills; When the diameter that increases the contact bottom layer parallel if desired improves the service life of forming web, must increase the diameter of contact bottom layer warp simultaneously, so also increase the bad thickness of three formable layer nets.
Foregoing has illustrated the mesh of evenly arranging, the dewatering that guarantees forming web, improve service life, reduce the bad thickness of forming web, equipment with same quantity or same production capacity in the production process provides more kinds to satisfy the demand of how different paper mills, be the due important performance of forming web and produce in be necessary the factor considered.
