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 to paper, wherein fourdrinier machine is the capital equipment of paper industry enterprise, in fourdrinier machine paper-making process, paper pulp is transported to head box, and be ejected on shaping wire side by head box, forming net is to weave the annular that forms guipure for no reason by macromolecular material, on paper machine, forming net is at breast roll, couch roll, drive net roller, between multiple deflector rolls such as wite roll with certain speed round and round, various dewater units in 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 guipure running, moisture in paper pulp and other liquid are filtered, raw fiber in paper pulp is separated from aqueous medium, shaping surface layer at forming net forms wet web, and enter pressed zone by transfer device after suction couch roll, wet web is by behind pressed zone, be transported to dry section, further remove the moisture in paper web in dry section, to reach processing and the packing instructions of 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 is also the traffic direction of fabric on paper machine.
CMD: the traffic direction of paper machine or filter vertical laterally, be also the vertical direction of the traffic direction of fabric on machine.
Warp: on paper machine or filter traffic direction, MD direction forms the yarn of fabric vertical structure.
Parallel: on vertical paper machine or filter traffic direction, CMD direction forms the yarn of fabric transversary.
Shaping surface layer: the fabric on paper machine or filter can be sandwich construction, contacts with filter medium, and fiber is played to the surface layer of direct supporting role.
Contact bottom layer: the fabric on paper machine or filter can be sandwich construction, the bottom contacting 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, every warp or parallel form separately independently path, in the description of this patent, are referred to as interleaved path.And in multiply cloth, an interleaved path can be formed by solid wire, also can jointly be formed by many equidirectional adjacent lines.
In this description, comprise that shaping surface layer warp is called for short face warp; Shaping surface layer parallel is called for short face picks; Warp at the bottom of contact bottom layer warp abbreviation face; Contact bottom layer parallel is called for short back weft.
Riser: when warp intersects with parallel, the crosspoint that warp forms above parallel.
Latitude floating-point: when warp intersects with parallel, the crosspoint that warp forms below parallel.
Fly number: in textile industry, the dislocation quantity of identical two the adjoining yarns of the bending rule of fabric, equidirectional dislocation successively.
In 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 wire mark necessary requirement especially, the general tiny 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 simultaneously will ensure the one-tenth paper layer of fabric is in essentially identical surface and have a good strainability, namely fabric has high retention and has water filtering performance fast filter medium, 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 etc.
Fabric has thin thickness not only can improve dewatering, also the energy consumption that reduces paper machine is had to positive effect.The fine mesh of fabric and thin thickness conventionally need the warp of fabric and the diameter of parallel less, this just causes bad impact to the ABRASION RESISTANCE of contact bottom layer, simultaneously because the tiny intensity of fabric in MD direction that also reduced of warp.
In order to address the above problem the performance that improves fabric, design multiply cloth, make the one-tenth paper layer of fabric there is tiny mesh, thin thickness, be beneficial to the shaping of paper and be dried, improve the diameter of contact bottom layer parallel to improve the ABRASION RESISTANCE of forming net, for example, designed multiply cloth, uses 2 groups of paper profiled surface CMD direction yarns, 2 groups of machine side surface yarns and 1 group of MD yarn formation to become paper layer and durable machine side surface layer compared with fine mesh, it is commonly called two-layer fabric, also has 1 group of paper profiled surface CMD direction yarn of use, 1 group of machine side surface yarn and 2 groups of MD yarns, 1 group of stitching yarns to form compared with 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 fabric reduction of water filtering performance and increase of production cost of higher thread density from another aspect, the in the situation that of lower thread density, produce again the deficiency of structural stability aspect, or becoming paper layer that the structural stability that is less than contact bottom layer warp and affect the CMD direction of surface layer is provided.
Therefore, do not wish that the diameter of the yarn of fine mesh produces the deficiency of fabric construction stability aspect simultaneously, fabric should have the dehydrating effect that good stability is become reconciled when high-speed cruising on paper machine in addition, and high retention, to ensure carrying out smoothly the service life long with fabric of papermaking, and reduce the manufacturing cost of fabric, improve the manufacture efficiency of fabric.
Summary of the invention
