Description
Technical field
The present invention relates to paper technology.More specifically, the present invention relates to a kind of forming fabric that is used for the paper machine molded component.
Background technology
In paper-making process, be the aqueous dispersion of cellulose fibre by deposit fiber slip on the mobile forming fabric in the paper machine molded component, thereby form cellulosic fibrous web.A large amount of water passes forming fabric by slip and discharges, thereby stays cellulosic fibrous web on the forming fabric surface.
The new cellulosic fibrous web that forms advances to pressing part from this molded component, and described pressing part includes a series of press. nips.This cellulosic fibrous web is by press. nips, and described press. nips is supported by press fabric, or is supported under normal conditions between two press fabrics.In this press. nips, cellulosic fibrous web is under pressure, this pressure moisture of from grid, squeezing out, and make the cellulose fibre in this grid adhered to one another, thus make this cellulosic fibrous web become paper.Moisture is received by press fabric, does not return in the paper and it is desirable to moisture.
Paper advances to drying part at last, and these parts comprise at least one group of rotatable dryer drums or the cylinder that heat internally with steam.The paper of just having made by the dryer fabric guiding rouses around each group along the circuitous path order, and described dryer fabric is attached on the bulging surface paper tightly.Heating drum makes the moisture of paper drop to desired level by evaporation.
It should be understood that shaping, squeezing and dryer fabric all take the form of endless on paper machine, and move in the mode of conveyer belt.It should be understood that more papermaking is a kind of continuous manufacture process of carrying out with appreciable speed.That is to say that me fibrous slurry constantly is deposited on the forming fabric of molded component, and newly formed paper is after leaving dryer part, by continuous reeling on roller.
Press fabric also relates to the last processed of paper surface.Just, press fabric is designed to have smooth surface and uniform elastic construction, and therefore, paper is endowed smooth traceless surface in the process by press. nips.
Press fabric receives the large quantity of moisture of being squeezed out by the l Water Paper in the press. nips.In order to realize this function, must have the space in the press fabric, be commonly referred to as " void volume ", pass through for moisture; And in the whole service life of fabric, sufficient permeability must be arranged to water.At last, press fabric must be able to prevent to return this paper again by the moisture that l Water Paper receives, and at rewetting profit paper when press. nips is left.
Woven fabric can take a number of different forms.For example, they can be made into for no reason, or first plain weave forms endless form with seam again.
The present invention be more particularly directed to be used for the forming fabric of molded component.Forming fabric is being played the part of crucial role in paper-making process.As previously mentioned, one of its function is the shaping paper products and it is delivered to pressing part.
But forming fabric also needs to solve the problem that moisture is discharged and paper is shaped.That is to say that forming fabric is designed to allow that moisture passes through (promptly controlling discharge rate), stops fiber and other solid to pass with water simultaneously.If draining too soon or too slow, paper quality and machine efficiency all can be impaired so.In order to control draining, must design validly and be used in the forming fabric space of draining being commonly referred to void volume.
At present, made polytype forming fabric, it designs in order to satisfy the demand of various paper machines, and the forming fabric that is used to make required grade paper has been installed on these paper machines.Usually, they comprise the base fabric that is made into by monofilament, and it can be individual layer or multilayer.Usually, yarn is to be extruded by any one of several synthetic polymer resins to obtain, for example polyamide and mylar, and they are that paper machine is employed for this reason with the fabric those skilled in the art.
The design of forming fabric also relates between required fiber support and fabric stability makes compromise.Fine mesh fabric can provide required paper surface nature, causes short fabric life but such design may lack required stability.Relatively, coarse mesh fabrics is that cost provides stability and long service life with the fiber support.Support and optimal stabilityization for reduce design compromises and make as far as possible, developed the multiple field fabric, for example, in bilayer and treble cloths, the design forming face designs wear surface at stability and drainage simultaneously for support.
In addition, three layers of design can independently be made into the profiled surface of fabric with wear surface respectively.Because this independence, three layers of design can provide high-caliber fiber support and best internal void volume.Therefore, three layers of design can provide aspect draining than individual layer and the more significant improvement of double layer design.
Basically, treble cloths by two fabrics promptly be shaped the layer and wearing layer form, described two fabrics by the binding yarn link together.This binding is very important to the globality of fabric.A problem of treble cloths is the relative slippage between two layers, can make this fabric fracture as time passes.In addition, link that yarn can destroy the structure of the layer that is shaped and the marking that causes paper.
The present invention describes a kind of three layer forming fabric, and this fabric has paired inherent tie lines and wear side warp runners.The present invention provides a kind of solution to the wear problem on the fabric machine side, and the good fiber support with less aperture and suitable void volume is provided simultaneously.
Summary of the invention
Therefore, the present invention relates to a kind of forming fabric that is used for the molded component of paper machine, but also can be used in the squeezing and/or drying part of paper machine.
Fabric of the present invention is a three layer forming fabric, have by first system (W11 W12) interweaves with cross-machine direction (CD) weft yarn of first system and the ground floor that forms and interweaved and the second layer that forms by the CD weft yarn of the MD warp thread of second system and second system along machine direction (MD) warp thread in pairs.Described paired MD warp thread in ground floor, thereby and and the CD weft yarn of second system interweave the second layer combined with ground floor.The MD warp thread of second system forms long flotation line or warp-runners on the outer surface of the second layer.Ground floor is the forming face of this fabric, and the second layer is the wear surface of this fabric.In this way, can make the treble cloths that contains paired inherent tie lines and warp-runners, and have the wear side abrasion resistance of improvement.
Fabric of the present invention be that described paired MD warp thread is in the second layer on the other hand.The paired warp of the second layer helps to protect the node between the described layer.Because each wear weft is all passed through under at least two continuous wear warps, this wear warps can be tangled more powerfully, thereby produces the plane difference bigger than suitable existing fabric.
Others of the present invention comprise that fabric can have the different weft yarn ratios of first CD of the system weft yarn to second CD of the system weft yarn.Long flotation line can have different length.Fabric can or be endless form by plain weave.Some yarn can have different diameters and/or shape.
The present invention will come to illustrate in further detail with reference to the following drawings.
