Definitions
- the present invention relates to the papermaking arts. More specifically, the present invention relates to forming fabrics for the forming section of a paper machine.
- a cellulosic fibrous web is formed by depositing a fibrous slurry, that is, an aqueous dispersion of cellulose fibers, onto a moving forming fabric in the forming section of a paper machine. A large amount of water is drained from the slurry through the forming fabric, leaving the cellulosic fibrous web on the surface of the forming fabric.
- a fibrous slurry that is, an aqueous dispersion of cellulose fibers
- the newly formed cellulosic fibrous web proceeds from the forming section to a press section, which includes a series of press nips.
- the cellulosic fibrous web passes through the press nips supported by a press fabric, or, as is often the case, between two such press fabrics.
- the press nips the cellulosic fibrous web is subjected to compressive forces which squeeze water therefrom, and which adhere the cellulosic fibers in the web to one another to turn the cellulosic fibrous web into a paper sheet.
- the water is accepted by the press fabric or fabrics and, ideally, does not return to the paper sheet.
- the paper sheet finally proceeds to a dryer section, which includes at least one series of rotatable dryer drums or cylinders, which are internally heated by steam.
- the newly formed paper sheet is directed in a serpentine path sequentially around each in the series of drums by a dryer fabric, which holds the paper sheet closely against the surfaces of the drums.
- the heated drums reduce the water content of the paper sheet to a desirable level through evaporation.
- the forming, press and dryer fabrics all take the form of endless loops on the paper machine and function in the manner of conveyors. It should further be appreciated that paper manufacture is a continuous process which proceeds at considerable speeds. That is to say, the fibrous slurry is continuously deposited onto the forming fabric in the forming section, while a newly manufactured paper sheet is continuously wound onto rolls after it exits from the dryer section.
- An alternative process employs a through air drying (TAD) unit either replacing the press fabric above with another woven fabric which transfers the sheet from the forming fabric to the through air drying fabric. It is this fabric which transfers the sheet to a TAD cylinder where hot air is blown through the wet cellulosic sheet, simultaneously drying the sheet and enhancing sheet bulk and softness.
- TAD through air drying
- Woven fabrics take many different forms. For example, they may be woven endless, or flat woven and subsequently rendered into endless form with a seam.
- the present invention relates specifically to the forming fabrics used in the forming section.
- Forming fabrics play a critical role during the paper manufacturing process.
- One of its functions, as implied above, is to form and convey the paper product being manufactured to the press section.
- forming fabrics also need to address water removal and sheet formation issues. That is, forming fabrics are designed to allow water to pass through (i.e. control the rate of drainage) while at the same time prevent fiber and other solids from passing through with the water. If drainage occurs too rapidly or too slowly, the sheet quality and machine efficiency suffers. To control drainage, the space within the forming fabric for the water to drain, commonly referred to as void volume, must be properly designed.
- Contemporary forming fabrics are produced in a wide variety of styles designed to meet the requirements of the paper machines on which they are installed for the paper grades being manufactured. Generally, they comprise a base fabric woven from monofilament and may be single-layered or multi-layered. The yarns are typically extruded from any one of several synthetic polymeric resins, such as polyamide and polyester resins, used for this purpose by those of ordinary skill in the paper machine clothing arts.
- the design of forming fabrics additionally involves a compromise between the desired fiber support and fabric stability.
- a fine mesh fabric may provide the desired paper surface and fiber support properties, but such design may lack the desired stability resulting in a short fabric life.
- coarse mesh fabrics provide stability and long life at the expense of fiber support and the potential for marking.
- multi-layer fabrics were developed. For example, in double and triple layer fabrics, the forming side is designed for support while the wear side is designed for stability.
- TSS triple stacked shute
- multi-layer fabrics have more cross-directional stability and stiffness to prevent cross directional shrinkage, improve sheet formation and appearance, and potentially increase life.
- the present invention is a forming fabric with twinned top wefts and an extra layer of middle wefts.
- the present invention provides a solution to the problems of drainage, sheet fiber support, and fabric stability.
- the present invention is a forming fabric, although it may find application in the forming, pressing and drying sections of a paper machine.
- the present invention is a fabric having a desirable non-uniform surface.
- the top-layer or forming side wefts in the present invention are twinned together into pairs. This results in a small open space between the paired wefts and a larger space between adjacent pairs.
- the present invention has non-equal spacing between adjacent wefts, whereas prior art fabrics have equal spacing between every adjacent forming side weft.
- the invention utilizes a third set of wefts, in the middle layer of the fabric, to provide extra stability in the cross direction.
- the fabric is a forming fabric having a top layer, a middle layer, and a bottom layer of cross-machine direction (CD) wefts and a system of machine-direction (MD) warp yarns interwoven with the top, middle, and bottom layers of CD wefts.
- the CD wefts in the top layer are grouped into twinned pairs to produce a non-uniform spacing between wefts in the top layer.
- the CD wefts in the middle layer provide extra stability in the CD.
- the CD wefts in the middle layer and bottom layer are vertically stacked, while the CD wefts in the top layer are vertically offset from the stacked middle and bottom layer CD wefts.
- the top layer of CD yarns forms the forming side of the fabric and the bottom layer of CD yarns forms the wear side of the fabric.
- shute (weft) twinning in the top surface of this fabric provides for increased CD tensile strength in the sheet of formed tissue paper. This gain in CD tensile allows for other changes in the process to be implement, which result in improved sheet formation, softness, and water absorbency.
- the fabric is woven in an eight-shed 2.5 layer weave pattern, wherein each MD yarn weaves: a) upward between two top-layer CD wefts in a pair; b) under the following pair; c) downward between the two top-layer CD wefts in the next pair; d) over the next vertically stacked middle-layer/bottom-layer CD wefts; e) between the next vertically stacked middle-layer/bottom-layer CD wefts; f) under the next vertically stacked middle-layer/bottom-layer CD wefts; g) between the next vertically stacked middle-layer/bottom-layer CD wefts; h) under the next vertically stacked middle-layer/bottom-layer CD wefts; i) between the next vertically stacked middle-layer/bottom-layer CD wefts; and j) upward between the next two top-layer CD wefts in a twin, thereby completing one repeat of the weave pattern.
- non-uniform spacing between wefts in the top layer has a spacing ratio between 1:1.5 and 1:20.
- FIG. 1 is a schematic view showing the spacing between forming-side wefts in forming fabrics according to: a) the prior art and b) the present invention;
- FIG. 2 is a forming side (top) view of a fabric woven in accordance with the teachings of the present invention
- FIG. 3 is a schematic cross-sectional view in the CD of a fabric pattern in accordance with the teachings of the present invention.
- FIG. 4 shows cross-sectional views in the CD of a fabric woven in accordance with the teachings of: a) the present invention and b) the prior art.
- FIG. 1 is a schematic view providing a comparison between the weft/shute spacing in the top (or forming) layer of prior art fabrics and the present invention.
- Each vertical stripe in the figure represents a forming side weft.
- FIG. 1 a shows the weft spacing according to the prior art
- FIG. 1 b shows the weft spacing according to the present invention. Note that in FIG. 1 a , the spacing of Gap 1 ( 110 ) is approximately equal to the spacing of Gap 2 ( 100 ). Whereas, in FIG. 1 b , the wefts are unevenly spaced.
- wefts A and B are characterized as twinned, or paired, wefts 130 . This twinning/pairing is considered beneficial as the non-uniform spacing helps promote drainage and conceals the diagonal sheet mark.
- a sample forming fabric has been produced in accordance with the teachings of the present invention. Measurements taken from this sample fabric show that the forming side wefts 120 have a cross-sectional diameter of 0.165 mm, Gap 1 ( 140 ) between twinned wefts 130 is only 0.081 mm, and Gap 2 ( 150 ) between adjacent pairs is 0.307 mm. By contrast, measurements taken from a typical prior art forming fabric, show that the forming side wefts 120 typically have a cross-sectional diameter of 0.165 mm and the spacing between wefts is approximately 0.27 mm. Thus, as indicated by FIG.
- this sample fabric according to the present invention has a spacing ratio of 1:3. It is an object of the present invention to cover a range of spacing ratios between 1:1.5 and 1:20.
- FIG. 2 shows a topside view of the forming side of a fabric according to the teachings of the present invention.
- the MD yarns 200 appear horizontally across the figure.
- Pairs of top-layer/forming-side wefts 220 are spaced together to form twinned pairs of shutes. These pairs are spaced apart by a multiple of the distance between the wefts in each pair.
- Shute 210 is a middle layer weft. These middle wefts reside in a lower plane/layer than the forming side wefts and are vertically stacked over the wear-side wefts. These middle layer wefts provide cross directional stability and prevent fabric shrinkage in the CD.
- FIG. 3 is a schematic cross-sectional view of a fabric pattern in accordance with the teachings of the present invention.
- the middle wefts are stacked directly above the bottom layer (wear side) wefts, while the twinned top layer (forming side) wefts are horizontally offset from the stacked middle and wear side wefts.
- this type of fabric structure may be described as unstacked cloth.
- the specific position of the forming, middle, and wear wefts, in relation to each other, helps promote a thin caliper and lower void volume; both benefits for paper machine applications.
- the weave pattern shown in FIG. 3 is simply one embodiment of the present invention.
- the forming fabric is woven in an eight-shed 2.5 layer weave pattern, wherein each warp yarn weaves: a) upward between two top-layer weft yarns in a twin; b) under the following twin; c) downward between the two top-layer weft yarns in the next twin; d) over the next vertically stacked middle-layer/bottom-layer weft yarns; e) between the next vertically stacked middle-layer/bottom-layer weft yarns; f) under the next vertically stacked middle-layer/bottom-layer weft yarns; g) between the next vertically stacked middle-layer/bottom-layer weft yarns; h) under the next vertically stacked middle-layer/bottom-layer weft yarns; i) between the next vertically stacked middle-layer/bottom-layer weft yarns; and j) upward between the next two top-layer weft yarns in
- FIG. 4 shows cross-sectional views of a fabric woven in accordance with the teachings of: a) the present invention and b) the prior art.
- prior art fabrics have three layers of wefts stacked in the vertical direction.
- the forming side wefts are not twinned, there is equal spacing between each top-layer shute.
- the fabric according to the invention shown in FIG. 4 a , has twinned top-layer (forming side) wefts 400 .
- the spacing between the wefts in a pair is significantly less than the spacing between pairs.
- the white arrow 402 indicates a middle layer weft which is stacked over the bottom layer weft.
- the top layer pair 400 is offset from the stacked middle and bottom layer wefts.
- the fabric according to the present invention preferably comprises only monofilament yarns.
- the CD yarns may be polyester monofilament and/or some may be polyester or polyamide.
- the CD and MD yarns may have a circular cross-sectional shape with one or more different diameters. Further, in addition to a circular cross-sectional shape, one or more of the yarns may have other cross-sectional shapes such as a rectangular cross-sectional shape or a non-round cross-sectional shape.
