Description
Invention field
The present invention relates to filter and papermaker's fabric, in paper industry, claim forming net.
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 shaping wire side by head box, forming net is to weave the annular guipure for no reason that forms by macromolecular material, on paper machine, forming net 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 net contact bottom layer, such as suction box, Wiper blade, paper pulp is injected into the shaping surface layer of shaping guipure, in the guipure running, moisture in the paper pulp and other liquid are filtered, raw fiber in the paper pulp is separated from aqueous medium, shaping surface layer at forming net forms wet web, and after suction couch roll, enter pressed zone by transfer device, wet web is by after the pressed zone, be transported to dry section, further remove moisture in the paper web at dry section, with processing and the packing instructions that reach later process.
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 or filter also is the traffic direction of fabric on the paper machine.
CMD: the traffic direction of paper machine or filter vertical laterally, also be the vertical direction of the traffic direction of fabric on machine.
Warp: on paper machine or filter traffic direction, promptly the MD direction constitutes the yarn of fabric vertical structure.
Parallel: on vertical paper machine or filter traffic direction, promptly the CMD direction constitutes the yarn of fabric transversary.
The shaping surface layer: the fabric on paper machine or filter can be sandwich construction, contacts with filter medium, and fiber is played the surface layer of direct supporting role.
Contact bottom layer: the fabric on paper machine or filter can be sandwich construction, the bottom that contacts with the dewatering elements of the wet end of machine.
Interleaved path: in the braiding process of woven, warp and parallel interweave by specific braiding pattern, and every warp or parallel form independent paths separately, are referred to as interleaved path in the description of this patent.And in multiply cloth, an interleaved path can be formed by solid wire, also can be formed jointly by many equidirectional adjacent lines.
In this specification, comprise that shaping surface layer warp is called for short the face warp; Shaping surface layer parallel is called for short face picks; Warp at the bottom of the contact bottom layer warp abbreviation face; The contact bottom layer parallel is called for short back weft.
Riser: when warp intersects with parallel, the crosspoint that warp forms above parallel.
The latitude floating-point: when warp intersects with parallel, the crosspoint that warp forms 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, forming net has tiny mesh, thin thickness and to produce as far as possible little wire mark on the surface of paper be very important, especially for the paper that has high printing quality to require, eliminate the necessary especially requirement of wire mark, the general tiny and uniform forming web of shaping surface layer mesh that uses, improve into the enabling capabilities of paper layer to paper pulp fiber, the upper end of yarn that will guarantee the one-tenth paper layer of fabric simultaneously is in essentially identical surface and has strainability preferably, just fabric has high retention and water filtering performance is fast arranged filter medium, and the forming net with such performance can be used for the newsprint of manufacturing paper with pulp, electro-photographic paper, writing paper, printing paper, art paper or the like.
Fabric has thin thickness not only can improve dewatering, also the energy consumption that reduces paper machine is had positive effect.The fine mesh of fabric and thin thickness need the diameter of the warp of fabric and parallel less usually, and this just causes bad influence to the ABRASION RESISTANCE of contact bottom layer, simultaneously because of the tiny intensity of fabric on the MD direction that also reduced of warp.
In order to address the above problem the performance that improves fabric, designed multiply cloth, make the one-tenth paper layer of fabric have tiny mesh, thin thickness, be beneficial to the shaping and the drying of paper, the diameter that improves the contact bottom layer parallel has for example been designed multiply cloth to improve the ABRASION RESISTANCE of forming net, uses 2 groups of paper profiled surface CMD direction yarns, 2 groups of machine side surface yarns and 1 group of MD yarn to form and becomes paper layer and durable machine side surface layer than fine mesh; It is commonly called two-layer fabric, also has to use 1 group of paper profiled surface CMD direction yarn, 1 group of machine side surface yarn and 2 groups of MD yarns, 1 group of stitching yarns formation than the shaping surface layer of fine mesh and durable machine side surface layer; It is commonly called treble cloths, 97182244.2,97182245.X, 01804768.8,02141980.9,02800379.9,200510076510.8,200710100644.8 and the U.S. 5881764,5967195,6123116,6145550,6745797,7243687,2004082465,200701577987 disclosed multiply cloths, these fabrics provide the mesh of very tiny one-tenth paper layer, but produce the reduction of fabric water filtering performance under the situation of higher thread density and the increase of production cost from another aspect, under the situation of low thread density, produce the deficiency aspect the structural stability again; Perhaps becoming the paper layer that the structural stability that is less than the contact bottom layer warp and influences the CMD direction of surface layer is provided.
Therefore, do not wish simultaneously that the diameter of the yarn of fine mesh produces the deficiency of fabric construction stability aspect, fabric should have the dehydrating effect that good stable is become reconciled during high-speed cruising on paper machine in addition, and high retention, so that guarantee carrying out smoothly the service life long of papermaking with fabric, and the manufacturing cost of minimizing fabric, the manufacturing efficient of raising fabric.
Summary of the invention
