Definitions
- the present invention relates to a papermaking fabric, in particular intended for use as a forming fabric in a forming section of a papermaking machine
- the traditional fourdrinier papermaking process mainly provides three successive steps, carried out in the corresponding sections of the papermaking machine: forming section, pressing section, drying section.
- an aqueous pulp of cellulose fibers (and any possible other components) is arranged on a so-called forming fabric or canvas, which is tape-shaped closed in a loop and supported by rollers.
- the removal of water from the pulp through the forming fabric leads to the progressive formation of a wet paper material tape, with a relatively high water content still remaining.
- a further removal of water takes place in the pressing section, in which the paper material is pressed by passing through one or more pairs of rollers.
- the paper material is then sent to the drying section for final moisture removal.
- the paper thus formed is ready for the subsequent finishing and packaging steps.
- machine direction (abbreviated “MD") and “cross machine direction” (abbreviated “CMD”) are used to indicate respectively a direction aligned with the feed direction of the forming fabric in the papermaking machine, and a direction parallel to the fabric surface and crosswise (perpendicular) to the feed direction.
- direction or orientation of the warp and weft yarns of the forming fabric are indicated with reference to the machine direction and cross machine direction. It is also intended, again as customary in the industry, that the surface of the forming fabric in contact with the cellulose pulp (i.e. with the paper material being formed) is the top surface of the fabric; and that the opposite surface facing the machine is the bottom surface. This reference is also adopted to describe the vertical spatial arrangement of the yarns in the forming fabric.
- Some characteristics of the papermaking fabrics are of particular importance, such as the support capacity and filtration capacity, especially in the forming section.
- the papermaking fabrics should show excellent stability even when moved at high speeds, a high permeability to reduce the amount of water retained in the pulp when transferred to the pressing section, and a reduced energy consumption for the handling thereof.
- WO2014/091410 describes a papermaking fabric having a top layer formed by top CMD yarns interwoven only with top MD yarns; a bottom layer formed by bottom yarns CMD interwoven only with bottom MD yarns; binding yarns are interwoven with both the top and bottom MD yarns, therefore binding the top and bottom layer.
- the fabric structure has a direct impact on the quality of the paper sheet being formed on the fabric, intimately in contact with the same: but the way in which structural changes to the fabric may affect the quality of the paper is not predictable.
- the present invention therefore relates to a papermaking fabric as defined, in essential terms, in the appended claim 1 and, in its additional characters, in the dependent claims.
- the present invention also relates to the use of said fabric in a papermaking machine, and specifically in the forming section of the machine, as defined in the appended claim 18.
- the invention provides a papermaking fabric which, as some known fabrics, has a two layer structure, each of which is formed by independent weft and warp yarns, and a binding system formed by pairs of binding yarns; however, the invention is distinguished by the specific fabric structure which allows a fully effective fabric to be obtained, high drainage, resistant and stable in time, and capable of ensuring the formation of high quality paper.
- FIG. 1 is a schematic top plan view of a top fabric layer according to the invention, of which a fabric repeating unit is shown;
- FIG. 2 is a schematic top plan view of a bottom fabric layer of Figure 1 ;
- Figures 3a, 3b, 3c are sectional views according to the trace planes Illa-IIIa, Illb-IIIb, IIIc-IIIc of Figures 1 and 2, respectively;
- FIG. 4 is a schematic top plan view of an alternative of the top fabric layer according to the invention.
- FIG. 5 is a schematic top plan view of a bottom fabric layer of Figure 4.
- FIGS. 6a, 6b, 6c, 6d are sectional views according to the trace planes Vla-VIa, VIb-VIb, VIc-VIc, VId-VId of Figures 4 and 5, respectively;
- FIG. 7 is a view in machine direction (warp) of a detail of the fabric of the invention.
- the number 100 denotes as a whole a papermaking fabric, in particular a forming fabric for use in the forming section of a papermaking machine.
- the fabric 100 is a triple 16 harness fabric and comprises a top layer 101 and a bottom layer 102 formed, as usual, by respective repeat units which together form one fabric repeating unit 104; in Figures 1 and 2 a single fabric repeating unit 104 is shown; it is understood that in commercial and industrial applications the unit 104, as well as the repeat units of the individual layers 101, 102, may be repeated several times, both in machine direction and in cross machine direction, to form a fabric 100 having suitable sizes for use on a papermaking machine.
- the fabric 100 is formed by longitudinal warp yarns that extend in machine direction (MD) and cross weft yarns, substantially orthogonal to the preceding ones, which extend in cross machine direction (CMD) .
- MD yarns machine direction
- CMD yarns cross weft yarns which extend in cross machine direction
- a repeat unit 104 of the fabric 100 comprises eight top MD yarns 1-8, three top CMD yarns P6,P10,P14, eight bottom MD yarns 9-16, three bottom CMD yarns MC5,MC9,MC13, and four binding yarns L7 , L8 , LI 1 , L12 comprising respective support portions 115 and respective binding portions 116.

- the binding yarns L7,L8; L11,L12 of each pair are interwoven so that the support portions 115 of one are arranged over the binding portions 116 of the other.
- the pairs of binding yarns L7,L8; L11,L12, however, are offset with respect to adjacent top CMD yarns (between which the pair of binding yarns is arranged) , so as to pass over the top MD yarns that are left exposed by the adjacent top CMD yarns.
- Both binding yarns L7 , L8 , LI 1 , L12 of a pair pass under the transition yarns T.

- the binding yarns L7 , L8 , LI 1 , L12 of each pair follow an "over-3/under-l" sequence with respect to the top MD yarns 1-8, which is, specifically, the same sequence of the top CMD yarns P6,P10,P14 with respect to the top MD yarns 1-8.
- binding yarns L7 , L8 ; LI 1 , L12 of each pair together, follow an "under-l/over-5" sequence (pair of binding yarns L7,L8), or an "under-l/over-3" sequence (pair of binding yarns L11,L12), with respect to the bottom MD yarns 9-16.
- the two pairs of binding yarns L7,L8; L11,L12 can follow the same sequence (and in particular one of the two indicated) , preferably being offset by one position in cross machine direction with respect to one another.
- the interweave of the yarns L7 , L8 , LI 1 , L12 with the top MD yarns 1-8 and bottom MD yarns 9-16 can however assume other shapes.
- the fabric 100 has a ratio between weft and warp yarns of 4:1.
- ratio between the weft and warp yarns the ratio between the number of weft yarns that are repeated to form the fabric in machine direction and the number of the warp yarns that are repeated in cross machine direction to form the fabric.
- the fabric 100 there are four weft yarns for each warp; this corresponds to the manufacturing mode of the fabric: in the weaving on a loom, four weft yarns are inserted for each warp yarn.
- the fabric 100 In cross section (section perpendicular to the machine direction) , the fabric 100 thus has a sequence of four weft yarns that are repeated in machine direction for each warp yarn (that is alternately a top or bottom yarn depending on the weaving with the weft yarns) .
- the fabric repeating unit 104 is formed by a single warp yarn (MD yarn) every four weft yarns (CMD yarn) : for each warp yarn (which can be a top MD yarn 1-8 or a bottom MD yarn 9-16, depending on the weave with the weft CMD yarns), there is in fact one top CMD yarn (one of P6,P10,P14), one bottom CMD yarn (one of MC5,MC9,MC13) and a pair of binding yarns (L7,L8; L11,L12) .
- MD yarn every four weft yarns
- the ratio between weft and warp yarns of 4:1 reflects the weaving mode of the fabric 100; at each beat (or insertion) of the fabric forming frame, on each warp yarn four consecutive weft yarns are inserted.
- the fabric 100 has, therefore, a warp yarn every four weft insertions.
- Each top or bottom MD yarn is associated, in every frame insertion or beat, with a top CMD yarn, a bottom CMD yarn and a pair of binding yarns.
- the fabrics, according to the present invention can take various shapes.
- the number and/or the position of the binding yarn with respect to the number and/or the position of the top CMD yarns can be varied (for example there can be a binding yarn every two or three top CMD yarns, or there can be two or three or more binding yarns for each top CMD yarn) .
- top and bottom CMD yarns of the fabric repeating unit can vary with respect to what is described and illustrated purely by way of example.
- all the weaving patterns or structures described for the layers 101, 102 can be different from those illustrated and described; for example, the top surface of the fabric does not necessarily need to be formed by a four harness satin structure as shown, but can be like canvas, twill, broken twill, etc.; and the bottom surface of the fabric doesn't need to be a six harness broken twill structure, but can have another shape, such as a broken satin, plain structure (canvas), a broken twill, a twill, etcetera.
- further alternative structure patterns may be used in the fabric according to the present invention.
- Yarns of various shapes for example having a rounded or flattened section
- size for example, a rounded or flattened section
- the shape of the yarns used in the fabric of the invention can vary, also depending on the properties to impart to the final product.
- the yarns may be monofilament yarns, flat monofilament yarns, multifilament yarns, multifilament or monofilament interwoven yarns, yarns of any kind, or any combination thereof.
- the materials of which the yarns are made of can be those commonly used in the field.
- polyester, polyamide, polyamide/polyester yarns, or the like can be used.
- the technician skilled in the art will be able to select the materials of the yarns also as a function of the specific application for which the final fabric is intended to be used.
- the top MD yarns, the top CMD yarns and the binding yarns can have a diameter (equal or different from one another) comprised between about 0.10 and 0.25 mm; the bottom MD yarns can have a diameter between about 0.12 and 0.30 mm; the bottom CMD yarns can have a diameter between about 0.10 and 0.35 mm; these are purely exemplary dimensions, and yarns of other sizes can be used depending on specific needs.
- the knit also (i.e. the knit size) of the fabric may also vary.
- the knit size of the top surface can be between about 34x38 and 37x48 (warp yarns per cm x weft insertions per cm) and the total knit size may vary between about 66x74 and 78x96 (warp yarns per cm x weft insertion per cm) .
- a fabric with a ratio of 4:1 and with the bottom layer having an six harness interrupted twill structure, produced according to the invention, has, for example, the characteristics shown in Table 1.
- the top layer 101 still has a four satin structure: the top CMD yarns, of which only a pair of adjacent yarns P14,P2 are represented, are in fact interwoven with the top MD yarns 1-8 with a sequence "over- 3/under-l" (each top CMD yarn passes over three adjacent top MD yarns and under a following top MD yarn, and so on) .
- the bottom layer 102 has a structure: the bottom CMD yarns, of which only a pair of adjacent yarns MC13,MC1 are represented, are interwoven with the bottom MD yarns 9-16 with a sequence "over-3/under-l" (each bottom CMD yarn passes over one bottom MD yarn and under the following three adjacent bottom MD yarns, and so on) .
- FIGS 4, 5, 6c and 6d show a pair of binding yarns L15, L16, which together have the same interlacing as described above: each binding yarn L15, L16 binds (passes over) a tern of adjacent top MD yarns 1-8 and binds (passes under) a bottom MD yarn 9-16, in particular offset in the cross direction by an even number of machine positions (for example, four positions) with respect to the tern of bound top MD yarns.
- the binding yarn L15 ( Figure 6c) passes over (i.e. binds) the top MD yarns 1,2,3 and passes under (i.e. binds) the bottom MD yarn 15, which is offset by four positions in cross machine direction with respect to the top MD yarn 3;
- the binding yarn L16 ( Figure 6d) passes over the top MD yarns 5,6,7 and under the bottom MD yarn 11, which is also offset by four positions in cross machine direction with respect to the top MD yarn 7.
- the fabric repeating unit 104 at least a pair of overlapped MD yarns, i.e., one top MD yarn and one bottom MD yarn overlapping one another (belonging to the top layer 101 and to the bottom layer 102, respectively), as for example the top MD yarn 6 and the bottom MD yarn 14 located directly under the top MD yarn 14, cross each other in machine direction, i.e. in the warp direction, so as to define a pair of warp binding yarns MD6, MD14, while maintaining the weaving patterns of both the top layer 101 (example: four satin), and of the bottom layer 102 (example: interrupted six twill structure) .
- the warp binding yarns MD6, MD14 of each pair are arranged directly one over the other, and cross each other maintaining the same basic structure (four satin) .
- Each top MD yarn 1-8 and each bottom MD yarn 9-16 then maintains its weaving position even if acting as a warp binding yarn between the top layer 101 and the bottom layer 102.
- the warp binding yarns MD6, MD14 cross each other only once.
- each pair of overlapped MD yarn may cross each other, even all the pairs, to define respective pairs of warp binding yarns: preferably, adjacent pairs of warp binding yarns cross each other, in offset positions, in machine direction .
- the binding in machine direction applies to all the embodiments of the invention and to all the weaving patterns of the fabric 100 mentioned above and others, that furthermore, fall under the invention.
- the fabric 100 described above is used in a papermaking process, in particular in the forming section of a papermaking machine. The process comprises the steps of:
