     FIELD OF THE INVENTION 
     Our invention relates to paper products such as absorbent sheets. Our invention also relates to methods of making paper products such as absorbent sheets, as well as to structuring fabrics for making paper products such as absorbent sheets. 
     RELATED ART 
     The use of fabrics is well known in the papermaking industry for imparting structure to paper products. More specifically, it is well known that a shape can be provided to paper products by pressing a malleable web of cellulosic fibers against a fabric and then subsequently drying the web. The resulting paper products are thereby formed with a molded shape corresponding to the surface of the fabric. The resulting paper products also thereby have characteristics resulting from the molded shape, such as a particular caliper and absorbency. As such, a myriad of structuring fabrics has been developed for use in papermaking processes to provide products with different shapes and characteristics. And, fabrics can be woven into a near limitless number of patterns for potential use in papermaking processes. 
     One important characteristic of many absorbent paper products is softness—consumers want, for example, soft paper towels. Many techniques for increasing the softness of paper products, however, have the effect of reducing other desirable properties of the paper products. For example, calendering basesheets as part of a process for producing paper towels can increase the softness of the resulting paper towels, but calendering also has the effect of reducing the caliper and absorbency of the paper towels. On the other hand, many techniques for improving other important properties of paper products have the effect of reducing the softness of the paper products. For example, using wet and dry strength resins in a papermaking process can improve the underlying strength of paper products, but wet and dry strength resins also reduce the perceived softness of the products. 
     For these reasons, it is desirable to make softer paper products, such as absorbent sheets. And, it is desirable to be able to make such softer absorbent sheets through manipulation of a structuring fabric used in the process of making the absorbent sheets. 
     SUMMARY OF THE INVENTION 
     According to one aspect, our invention provides an absorbent sheet of cellulosic fibers. The absorbent cellulosic sheet includes a plurality of projected regions projecting from the absorbent sheet, wherein the projected regions include folds that are curved relative to the machine direction of the absorbent sheet. Ends of the curved folds are on opposite sides of the projected regions and such that one of the ends of each of the curved folds is positioned downstream from the other end of the curved folds in the machine direction of the absorbent sheet. Apexes of the curved folds are positioned downstream in the machine direction of the absorbent sheet. Further, connecting regions connecting the projected regions of the absorbent sheet. 
     According to another aspect, our invention provides an absorbent cellulosic sheet. A plurality of projected regions project from the absorbent sheet, wherein the projected regions include folds that are curved relative to the machine direction of the absorbent sheet. Ends of the curved folds are on opposite sides of the projected regions, and the curved folds have a radius of curvature of about 0.5 mm to about 2.0 mm. Further, connecting regions connecting the projected regions of the absorbent sheet. 
     According to a further aspect, our invention provides a papermaking web. The papermaking web comprises a plurality of projected regions projecting from the papermaking web, wherein the projected regions include folds that are curved relative to a machine direction of the absorbent sheet, with ends of the curved folds being on opposite sides of the projected regions and such that one of the ends of each of the curved folds is positioned downstream from the other end of the curved folds in the machine direction of the papermaking web. Apexes of the curved folds are positioned downstream in the machine direction of the papermaking web. Connecting regions form a network connecting the projected regions of the papermaking web. 
     According to yet another aspect, our invention provides a method of making a fabric-creped absorbent cellulosic sheet. The method includes compactively dewatering a papermaking furnish to form a web. The method also includes creping the web under pressure in a creping nip between a transfer surface and a structuring fabric. The structuring fabric includes knuckles formed on warp yarns of the structuring fabric, with the knuckles being positioned along lines that are angled relative to the machine direction of the fabric, wherein the angle of lines relative to the machine direction is between about 10° and about 30°. Further, the method includes a step of drying the web to form the absorbent cellulosic sheet. 
     According to yet another aspect, our invention provides an absorbent cellulosic sheet that includes a plurality of projected regions projecting from the absorbent sheet, with the projected regions including folds that are curved in the machine direction of the absorbent sheet, and with ends of the curved folds being on opposite sides of the projected regions. The absorbent sheet has a normalized fold curvature ratio that is less than about 4. The absorbent sheet also includes connecting regions forming a network connecting the projected regions of the absorbent sheet.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Our invention relates to paper products such as absorbent sheets and methods of making paper products such as absorbent sheets. Absorbent paper products according to our invention have outstanding combinations of properties that are superior to other absorbent paper products that are known in the art. In some specific embodiments, the absorbent paper products according to our invention have combinations of properties particularly well suited for absorbent hand towels, facial tissues, or toilet paper. 
     The term “paper product,” as used herein, encompasses any product incorporating papermaking fibers having cellulose as a major constituent. This would include, for example, products marketed as paper towels, toilet paper, facial tissue, etc. Papermaking fibers include virgin pulps or recycled (secondary) cellulosic fibers, or fiber mixes comprising cellulosic fibers. Wood fibers include, for example, those obtained from deciduous and coniferous trees, including softwood fibers, such as northern and southern softwood kraft fibers, and hardwood fibers, such as eucalyptus, maple, birch, aspen, or the like. Examples of fibers suitable for making the products of our invention include non-wood fibers, such as cotton fibers or cotton derivatives, abaca, kenaf, sabai grass, flax, esparto grass, straw, jute hemp, bagasse, milkweed floss fibers, and pineapple leaf fibers. 
     “Furnishes” and like terminology refers to aqueous compositions including papermaking fibers, and, optionally, wet strength resins, debonders, and the like, for making paper products. A variety of furnishes can be used in embodiments of our invention, and specific furnishes are disclosed in the examples discussed below. In some embodiments, furnishes are used according to the specifications described in commonly-assigned U.S. Pat. No. 8,080,130 (the disclosure of which is incorporated by reference in its entirety). The furnishes in this patent include, among other things, cellulosic long fibers having a coarseness of at least about 15.5 mg/100 mm. Examples of furnishes are also specified in the examples discussed below. 
     As used herein, the initial fiber and liquid mixture that is dried to a finished product in a papermaking process will be referred to as a “web” and/or a “nascent web.” The dried, single-ply product from a papermaking process will be referred to as a “basesheet.” Further, the product of a papermaking process may be referred to as an “absorbent sheet.” In this regard, an absorbent sheet may be the same as a single basesheet. Alternatively, an absorbent sheet may include a plurality of basesheets, as in a multi-ply structure. Further, an absorbent sheet may have undergone additional processing after being dried in the initial basesheet forming process in order to form a final paper product from a converted basesheet. An “absorbent sheet” includes commercial products marketed as, for example, hand towels. 
     When describing our invention herein, the terms “machine direction” (MD) and “cross machine direction” (CD) will be used in accordance with their well-understood meaning in the art. That is, the MD of a fabric or other structure refers to the direction that the structure moves on a papermaking machine in a papermaking process, while CD refers to a direction crossing the MD of the structure. Similarly, when referencing paper products, the MD of the paper product refers to the direction on the product that the product moved on the papermaking machine in the papermaking process, and the CD of the product refers to the direction crossing the MD of the product. In terms of the MD of the paper product, “downstream” refers to an area that is formed before an “upstream” area. 
       FIG. 1  shows an example of a papermaking machine  200  that can be used to make paper products according to our invention. A detailed description of the configuration and operation of papermaking machine  200  can be found in commonly-assigned U.S. Pat. No. 7,494,563 (“the &#39;563 patent”), the disclosure of which is incorporated by reference in its entirety. Notably, the &#39;563 patent describes a papermaking process that does not use through air drying (TAD). The following is a brief summary of a process for forming an absorbent sheet using papermaking machine  200 . 
     The papermaking machine  200  is a three-fabric loop machine that includes a press section  100  in which a creping operation is conducted. Upstream of the press section  100  is a forming section  202 . The forming section  202  includes headbox  204  that deposits an aqueous furnish on a forming wire  206  supported by rolls  208  and  210 , thereby forming an initial aqueous cellulosic web  116 . The forming section  202  also includes a forming roll  212  that supports a papermaking felt  102  such that web  116  is also formed directly on the felt  102 . A felt run  214  extends about a suction turning roll  104  and then to a shoe press section  216  wherein the web  116  is deposited on a backing roll  108 . The web  116  is wet-pressed concurrently with the transfer of the web  116  to the backing roll  108 , which carries the web  116  to a creping nip  120 . In other embodiments, however, instead of being transferred on the backing roll  108 , the web  116  by be transferred from the felt run  214  onto an endless belt in a dewatering nip, with the endless belt then carrying the web  116  to the creping nip  120 . An example of such a configuration can be seen in U.S. Pat. No. 8,871,060, which is incorporated by reference herein in its entirety. 
     The web  116  is transferred onto the structuring fabric  112  in the creping nip  120 , and then vacuum drawn by vacuum molding box  114 . After this creping operation, the web  116  is deposited on a Yankee dryer  218  in another press nip  217  using a creping adhesive that is applied to the surface of the Yankee dryer  218 . The web  116  is dried on Yankee dryer  218 , which is a heated cylinder, and the web  116  is also dried by high jet velocity impingement air in the hood around the Yankee dryer  218 . As the Yankee dryer  218  rotates, the web  116  is peeled from the dryer  218  at position  220 . The web  116  may then be subsequently wound on a take-up reel (not shown). The reel may be operated slower than the Yankee dryer  218  at steady-state in order to impart a further crepe to the web. Optionally, a creping doctor blade  222  may be used to conventionally dry-crepe the web  116  as it is removed from the Yankee dryer  218 . 
     In the creping nip  120 , the web  116  is transferred onto the top side of the structuring fabric  112 . The creping nip  120  is defined between the backing roll  108  and the structuring fabric  112 , with the structuring fabric  112  being pressed against the backing roll  108  by a creping roll  110 . Because the web  116  still has a high moisture content when it is transferred to the structuring fabric  112 , the web is deformable such that portions of the web can be drawn into pockets formed between the yarns that make up the structuring fabric  112 . (The pockets of structuring fabrics will be described in detail below.) In particular papermaking processes, the structuring fabric  112  moves more slowly than does the papermaking felt  102 . Thus, the web  116  is creped as it is transferred onto the structuring fabric  112 . 
     An applied suction from vacuum molding box  114  may also aid in drawing the web  116  into pockets in the surface of the structuring fabric  112 , as will be described below. When traveling along the structuring fabric  112 , the web  116  reaches a highly consistent state with most of the moisture having been removed. The web  116  is thereby more or less permanently imparted with a shape by the structuring fabric  112 , with the shape including domed regions where the web  116  is drawn into the pockets of the structuring fabric  112 . 
     Basesheets made with papermaking machine  200  may also be subjected to further processing, as is known in the art, in order to convert the basesheets into specific products. For example, the basesheets may be embossed, and two basesheets can be combined into multi-ply products. The specifics of such converting processes are well known in the art. 
     Using the process described in the aforementioned &#39;563 patent, the web  116  is dewatered to the point that it has a higher consistency when transferred onto the top side of the structuring fabric  112  as compared to an analogous operation in other papermaking processes, such as a TAD process. That is, the web  116  is compactively dewatered so as to have from about 30 percent to about 60 percent consistency (i.e., solids content) before entering the creping nip  120 . In the creping nip  120 , the web  116  is subjected to a load of about 30 pounds per linear inch (PLI) to about 200 PLI. Further, there is a speed differential between the backing roll  108  and the structuring fabric  112 . This speed differential is referred to as the fabric creping percentage, and may be calculated as: 
       Fabric Crepe %= S   1   /S   2 −1
 
     where S 1  is the speed of the backing roll  108  and S 2  is the speed of the structuring fabric  112 . In particular embodiments, the fabric crepe percentage, or “creping ratio,” can be anywhere from about 3% to about 100%. This combination of web consistency, speed differential occurring at the creping nip  120 , the pressure employed at the creping nip  120 , and the structuring fabric  112  and creping nip  120  geometry act to rearrange the cellulose fibers while the web  116  is still pliable enough to undergo structural change. In particular, without intending to be bound by theory, it is believed that the slower forming surface speed of the structuring fabric  112  causes the web  116  to be substantially molded into openings in the structuring fabric  116 , with the fibers being realigned in proportion to the creping ratio. 
     While a specific process has been described in conjunction with the papermaking machine  200 , those skilled in the art will appreciate that our invention disclosed herein is not limited to the above-described papermaking process. For example, as opposed to the non-TAD process described above, our invention could be related to a TAD papermaking process. An example of a TAD papermaking process can be seen in U.S. Pat. No. 8,080,130, the disclosure of which is incorporated by reference in its entirety. 
       FIG. 2  is a drawing showing details of a portion of the web contacting side of a structuring fabric  300  that has a configuration for forming paper products according to an embodiment of our invention. The structuring fabric  300  includes warp yarns  302  that run in the machine direction (MD) when the fabric is used in a papermaking process, and weft yarns  304  that run in the cross machine direction (CD). The warp and weft yarns  302  and  304  are woven together so as to form the body of the structuring fabric  300 . The web-contacting surface of the structuring fabric  300  is formed by knuckles (two of which are outlined in  FIG. 2  and labeled as  306  and  310 ), which are formed on the warp yarns  302 , but no knuckles are formed on the weft yarns  304 . It should be noted, however, that while the structuring fabric  300  shown in  FIG. 2  only has knuckles on the warp yarns  302 , our invention is not limited to structuring fabrics that only have warp knuckles, but rather, includes fabrics that have both warp and weft knuckles. Indeed, fabrics with only warp knuckles and fabrics with both warp and weft knuckles will be described in detail below. 
     The knuckles  306  and  310  in the structuring fabric  300  are in a plane that makes up the surface that the web  116  contacts during a papermaking operation. Pockets  308  (one of which is shown as the dotted outlined area in  FIG. 2 ) are defined in the areas between the knuckles  306  and  310 . Portions of the web  116  that do not contact the knuckles  306  and  310  are drawn into the pockets  308  as described above. It is the portions of the web  116  that are drawn into the pockets  308  that result in domed regions that are found in the resulting paper products. 
     Those skilled in the art will appreciate the significant length of warp yarn knuckles  306  and  310  in the MD of structuring fabric  300 , and will further appreciate that the fabric  300  is configured such that the long warp yarn knuckles  306  and  310  delineate long pockets in the MD. In particular embodiments of our invention, the warp yarn knuckles  306  and  310  have a length of about 2 mm to about 6 mm. Most structuring fabrics known in the art have shorter warp yarn knuckles (if the fabrics have any warp yarn knuckles at all). As will be described below, the longer warp yarn knuckles  306  and  310  provide for a larger contact area for the web  116  during the papermaking process, and, it is believed, might be at least partially responsible for the increased softness seen in absorbent sheets according to our invention, as compared to absorbent sheets with conventional, shorter warp yarn knuckles. 
     To quantify the parameters of the structuring fabrics described herein, the fabric characterization techniques described in the commonly-assigned U.S. Patent Application Publication Nos. 2014/0133734; 2014/0130996; 2014/0254885, and 2015/0129145 (hereafter referred to as the “fabric characterization publications”) can be used. The disclosures of the fabric characterization publications are incorporated by reference in their entirety. Such fabric characterization techniques allow for parameters of a structuring fabric to be easily quantified, including knuckle lengths and widths, knuckle densities, pocket areas, pocket densities, pocket depths, and pocket volumes. 
       FIGS. 3A-3E  indicate some of the characteristics of structuring fabrics made according to embodiments of our invention, which are labeled as Fabrics  1 - 15 .  FIG. 3F  also shows characteristics of conventional structuring fabrics, which are labeled as Fabrics  16  and  17 . Structuring fabrics of the type shown in  FIGS. 3A-3F  can be made by numerous manufacturers, including Albany International of Rochester, N.H., and Voith GmbH of Heidenheim, Germany. Fabrics  1 - 15  have long warp yarn knuckle fabrics such that the vast majority of the contact area in Fabrics  1 - 15  comes from the warp yarn knuckles, as opposed to weft yarn knuckles (if the fabrics have any weft yarn knuckles at all). Fabrics  16  and  17 , which have shorter warp yarn knuckles, are provided for comparison. All of the characteristics shown in  FIGS. 3A-3F  were determined using the techniques in the aforementioned fabric characterization publications, particularly, using the non-rectangular, parallelogram calculation methods that are set forth in the fabric characterization publications. Note that the indications of “N/C” in  FIGS. 3A-3F  mean that the particular characteristics were not determined. 
     The air permeability of a structuring fabric is another characteristic that can influence the properties of paper products made with the structuring fabric. The air permeability of a structuring fabric is measured according to well-known equipment and tests in the art, such as Frazier® Differential Pressure Air Permeability Measuring Instruments by Frazier Precision Instrument Company of Hagerstown, Md. Generally speaking, the long warp knuckle structuring fabrics used to produce paper products according to our invention have a high amount of air permeability. In a particular embodiment of our invention, the long warp knuckle structuring fabric has an air permeability of about 450 CFM to about 1000 CFM. 
       FIGS. 4A-4E  are photographs of absorbent sheets made with long warp knuckle structuring fabrics, such as those characterized in  FIGS. 3A-3E . More specifically,  FIGS. 4A-4E  show the air side of the absorbent sheets, that is, the side of the absorbent sheets that contacted the structuring fabric during the process of forming the absorbent sheets. Thus, the distinct shapes that are imparted to the absorbent sheets through contact with the structuring fabrics, including domed regions projecting from the shown side of the absorbent sheet, can be seen in  FIGS. 4A-4E . Note that the MD of the absorbent sheets is shown vertically in these figures. 
     Specific features of the absorbent sheet  1000  are annotated in  FIG. 5 , which is based on the photograph shown as  FIG. 4E . The absorbent sheet  1000  includes a plurality of substantially rectangular-shaped domed regions, some of which are outlined and labeled  1010 ,  1020 ,  1030 ,  1040 ,  1050 ,  1060 ,  1070 , and  1080  in  FIG. 5 . As explained above, the domed regions  1010 ,  1020 ,  1030 ,  1040 ,  1050 ,  1060 ,  1070 , and  1080  correspond to the portions of the web that were drawn into the pockets of the structuring fabric during the process of forming the absorbent sheet  1000 . Connecting regions, some of which are labeled  1015 ,  1025 , and  1035  in  FIG. 5 , form a network interconnecting the domed regions. The connecting regions generally correspond to portions of the web that were formed in the plane of the knuckles of the structuring fabric during the process of forming the absorbent sheet  1000 . 
     Those skilled in the art will immediately recognize several features of the absorbent sheets shown in  FIGS. 4A-4E and 5  that are different than conventional absorbent sheets. For instance, all of the domed regions include a plurality of indented bars formed into the tops of the domed regions, with the indented bars extending across the domed regions in the CD of the absorbent sheets. Some of these indented bars are outlined and labeled  1085  in  FIG. 5 . Notably, almost all of the domed regions have three such indented bars, with some of the domed regions having four, five, six, seven, or even eight indented bars. The number of indented bars can be confirmed using laser scan profiling (described below). Using such laser scan profiling, it was found that in a particular absorbent sheet according to an embodiment of our invention, there are, on average (mean), about six indented bars per domed region. 
     Without being limited by theory, we believe that the indented bars seen in the absorbent sheets shown in  FIGS. 4A-4E and 5  are formed when the web is transferred onto a structuring fabric with the configurations described herein during a papermaking process as described herein. Specifically, when a speed differential is used for creping the web as it is transferred onto the structuring fabric, the web “plows” onto the knuckles of the structuring fabric and into the pockets between the knuckles. As a result, folds are created in the structure of the web, particularly in the areas of the web that are moved into the pockets of the structuring fabric. An indented bar is thus formed between two of such folds in the web. Because of the long MD pockets in the long warp yarn knuckle structuring fabrics described herein, the plowing/folding effect takes place multiple times over a portion of a web that spans a pocket in the structuring fabric. Thus, multiple indented bars are formed in each of the domed regions of absorbent sheets made with the long warp knuckle structuring fabrics described herein. 
     Again, without being limited by theory, we believe that the indented bars in the domed regions may contribute to an increased softness that is perceived in the absorbent sheets according to our invention. Specifically, the indented bars provide a more smooth, flat plane being perceived when the absorbent sheet is touched, as compared to absorbent sheets having conventional domed regions. The difference in perceptional planes is illustrated in  FIGS. 6A and 6B , which are drawings showing cross sections of an absorbent sheet  2000  according to our invention and a comparison sheet  3000 , respectively. In absorbent sheet  2000 , the domed regions  2010  and  2020  include indented bars  2080 , with ridges being formed between the indented bars  2080  (the ridges/indents correspond to the folds in the web during the papermaking process as described above). As a result of the small indented bars  2080  and plurality of ridges around the indented bars  2080 , flat, smooth perceived planes P 1  (marked with dotted lines in  FIG. 6A ) are formed. These flat, smooth planes P 1  are sensed when the absorbent sheet  2000  is touched. We further believe that the users cannot detect the small discontinuities of the indented bars  2080  in the surfaces of the domed regions  2010  and  2020 , nor can users detect the short distance between the domed regions  2010  and  2020 . Thus, the absorbent sheet  2000  is perceived as having a smooth, soft surface. On the other hand, the perceived planes P 2  have a more rounded shape with the conventional domes  3010  and  3020  in comparison sheet  3000 , as shown in  FIG. 6B , and the conventional domes  3010  and  3020  are spaced apart. It is believed that because the perceived planes P 2  of the conventional domes  3010  and  3020  are spaced a significant distance from each other, the comparison sheet  3000  is perceived as less smooth and soft compared to the perceived planes P 1  found in the domed regions  2010  and  2020  with the indented bars  2080 . 
     Those skilled in the art will appreciate that, due to the nature of a papermaking process, not every domed region in an absorbent sheet will be identical. Indeed, as noted above, domed regions of an absorbent sheet according to our invention might have different numbers of indented bars. At the same time, a few of the domed regions observed in any particular absorbent sheet of our invention might not include any indented bars. This will not affect the overall properties of the absorbent sheet, however, as long as a majority of the domed regions includes the indented bars. Thus, when we refer to an absorbent sheet as having domed regions that include a plurality of indented bars, it will be understood that that absorbent sheet might have a few domed regions with no indented bars. 
     The lengths and depths of the indented bars in absorbent sheets, as well as the lengths of the domed regions, can be determined from a surface profile of a domed region that is made using laser scanning techniques, which are well known in the art.  FIGS. 7A and 7B  show laser scan profiles across domed regions in two absorbent sheets according to our invention. The peaks of the laser scan profiles are the areas of the domes that are adjacent to the indented bars, while the valleys of the profiles represent the bottoms of the indented bars. Using such laser scan profiles, we have found that the indented bars extend to a depth of about 45 microns to about 160 microns below the tops of the adjacent areas of the domed regions. In a particular embodiment, the indented bars extend an average (mean) of about 90 microns below the tops of the adjacent areas of the domed regions. In some embodiments, the domed regions extend a total of about 2.5 mm to about 3 mm in length in a substantially MD of the absorbent sheets. Those skilled in the art will appreciate that such lengths in the MD of the domed regions are greater than the lengths of domed regions in conventional fabrics, and that the long domed regions are at least partially the result of the long MD pockets in the structuring fabrics used to create the absorbent sheets, as discussed above. From the laser scan profiles, it can also be seen that the indented bars were spaced about 0.5 mm apart along the lengths of the domed regions in embodiments of our invention. 
     Further distinct features that can be seen in the absorbent sheets shown in  FIGS. 4A-4E and 5  include the dome regions being bilaterally staggered in the MD such that substantially continuous, stepped lines of domed regions extend in the MD of the sheets. For example, with reference again to  FIG. 5 , the domed region  1010  is positioned adjacent to the domed region  1020 , with the two domed regions overlapping in a region  1090 . Similarly, the domed region  1020  overlaps domed region  1030  in a region  1095 . The bilaterally staggered domed regions  1010 ,  1020 , and  1030  form a continuous, stepped line, substantially along the MD of the absorbent sheet  1000 . Other domed regions form similar continuous, stepped lines in the MD. 
     We believe that the configuration of the elongated, bilaterally staggered domed regions, in combination with the indented bars extending across the domed regions, results in the absorbent sheets having a more stable configuration. For example, the bilaterally staggered domed regions provide for a smooth planar surface on the Yankee side of the absorbent sheets, which thereby results in a better distribution of pressure points on the absorbent sheet. Note, the Yankee side of an absorbent sheet is the side of the absorbent sheets that is opposite to the air side of the absorbent sheets that is drawn into the structuring fabric during the papermaking process. In effect, the bilaterally staggered domed regions act like long boards in the MD direction that cause the absorbent sheet structure to lay flat. This effect, resulting from the combination of bilaterally staggered domed regions and indented bars will, for example, cause a web to better lay down on the surface of a Yankee dryer during a papermaking process, which results in better absorbent sheets. 
     Similar to the continuous lines of domed regions, substantially continuous lines of connecting regions extend in a stepped manner along the MD of the absorbent sheet  1000 . For example, connection region  1015 , which runs substantially in the CD, is contiguous with connecting region  1025 , which runs substantially in the CD. Connecting region  1025  is also contiguous with connecting region  1035 , which runs substantially in the MD. Similarly, connecting region  1015  is contiguous with connecting region  1025  and connecting region  1055 . In sum, the MD connecting regions are substantially longer than the CD connecting regions, such that lines of stepped, continuous connecting regions can be seen along the absorbent sheet. 
     As discussed above, the sizes of the domed regions and the connecting regions of an absorbent sheet generally correspond to the pocket and knuckle sizes in the structuring fabric used to produce the absorbent sheet. In this regard, we believe that the relative sizing of the domed and connecting regions contributes to the softness of absorbent sheets made with the fabric. We also believe that the softness is further improved as a result of the substantially continuous lines of domed regions and connecting regions. In a particular embodiment of our invention, a distance in the CD across the domed regions is about 1.0 mm, and a distance in the CD across the MD oriented connecting regions is about 0.5 mm. Further, the overlap/touching regions between adjacent domed regions in the substantially continuous lines are about 1.0 mm in length along the MD. Such dimensions can be determined from a visual inspection of the absorbent sheets, or from a laser scan profile as described above. An exceptionally soft absorbent sheet can be achieved when these dimensions are combined with the other features of our invention described herein. 
     In order to evaluate the properties of products according to our invention, absorbent sheets were made using Fabric  15  as shown  FIG. 3E  in a papermaking machine having the general configuration shown in  FIG. 1  with a process as described above. For comparison, products were made using the shorter warp length knuckle Fabric  17  (that is also shown in  FIG. 3F ) under the same process conditions. Parameters used to produce basesheets for these trials are shown in TABLE 1.

     Sheets formed in the trials with Fabric  15  (i.e., a long warp knuckle fabric) were found to be smoother and softer than the sheets formed in the trials with Fabric  17  (i.e., a shorter warp knuckle fabric). Other important properties of the sheets made with Fabric  15 , such as caliper and bulk, were found to be very comparable to those properties of the sheets made with Fabric  17 . Thus, it is clear that the basesheets made with the long warp knuckle Fabric  15  could potentially be used to make absorbent products that are softer than absorbent products with the shorter warp knuckle Fabric  17  without the reduction of other important properties of the absorbent products. 
     As described in the aforementioned fabric characterization publications, the planar volumetric index (PVI) is a useful parameter for characterizing a structuring fabric. The PVI for a structuring fabric is calculated as the contact area ratio (CAR) multiplied by the effective pocket volume (EPV) multiplied by one hundred, where the EPV is the product of the pocket area estimate (PA) and the measured pocket depth. The pocket depth is most accurately calculated by measuring the caliper of a handsheet formed on the structuring fabric in a laboratory, and then correlating the measured caliper to the pocket depth. And, unless otherwise noted, all of the PVI-related parameters described herein were determined using this handsheet caliper measuring method. Further, a non-rectangular, parallelogram PVI is calculated as the contact area ratio (CAR) multiplied by the effective pocket volume (EPV) multiplied by one hundred, where the CAR and EPV are calculated using a non-rectangular, parallelogram unit cell area calculation. In embodiments of our invention, the contact area of the structuring long warp knuckle fabric varies between about 25% to about 35% and the pocket depth varies between about 100 microns to about 600 microns, with the PVI thereby varying accordingly. 
     Another useful parameter for characterizing a structuring fabric related to the PVI is a planar volumetric density index (PVDI) of the structuring fabric. The PVDI of a structuring fabric is defined as the PVI multiplied by pocket density. Note that in embodiments of our invention, the pocket density varies between about 10 cm −2  to about 47 cm −2 . Yet another useful parameter of a structuring fabric can be developed by multiplying the PVDI by the ratio of the length and width of the knuckles of the fabric, thereby providing a PVDI-knuckle ratio (PVDI-KR). For example, a PVDI-KR for a long warp knuckle structuring fabric as described herein would be the PVDI of the structuring fabric multiplied by the ratio of warp knuckles length in the MD to the warp knuckles width in the CD. As is apparent from the variables used to calculate the PVDI and PVDI-KR, these parameters take into account important aspects of a structuring fabric (including percentage of contact area, pocket density, and pocket depth) that affect shapes of paper products made using the structuring fabric, and, hence, the PVDI and PVDI-KR may be indicative of the properties of the paper products such as softness and absorbency. 
     The PVI, PVDI, PVDI-KR, and other characteristics were determined for three long warp knuckle structuring fabrics according to embodiments of our invention, with the results being shown as Fabrics  18 - 20  in  FIG. 8 . For comparison, the PVI, PVDI, PVDI-KR, and other characteristics were also determined for a shorter warp knuckle structuring fabric, as is shown as Fabric  21  in  FIG. 8 . Notably, the PVDI-KRs for Fabrics  18 - 20  are about 43 to about 50, which are significantly greater than the PVDI-KR of 16.7 for Fabric  21 . 
     Fabrics  18 - 21  were used to produce absorbent sheets, and characteristics of the absorbent sheets were determined, as shown in  FIG. 9 . The characteristics shown in  FIG. 9  were determined using the same techniques that are described in the aforementioned fabric characterization publications. In this regard, the determinations of the interconnecting regions correspond to the warp knuckles on the structuring fabric, and the dome regions correspond to the pockets of the structuring fabric. Also, it could again be seen that the sheets made from the long warp knuckle Fabrics  18 - 20  have multiple indented bars in each dome region. On the other hand, the domed regions of the absorbent sheet formed from the shorter warp knuckle Fabric  21  had, at most, one indented bar, and many of the domed regions did not have any indented bars at all. 
     The sensory softness was determined for the absorbent sheets shown in  FIG. 9 . Sensory softness is a measure of the perceived softness of a paper product as determined by trained evaluators using standardized testing techniques. More specifically, sensory softness is measured by evaluators experienced with determining the softness, with the evaluators following specific techniques for grasping the paper and ascertaining a perceived softness of the paper. The higher the sensory softness number, the higher the perceived softness. In the case of the sheets made from Fabrics  18 - 20 , it was found that the absorbent sheets made with Fabrics  18 - 20  were 0.2 to 0.3 softness units higher than the absorbent sheets made with Fabric  21 . This difference is outstanding. Moreover, the sensory softness was found to correlate with the PVDI-KR of the fabrics. That is, the higher the PVDI-KR of the structuring fabric, the higher the sensory softness number that was achieved. Thus, we believe that PVDI-KR is a good indicator of the softness that can be achieved in a paper product made with a process using a structuring fabric, with a higher PVDI-KR structuring fabric producing a softer product. 
       FIGS. 10A-10D  show characteristics of further long-warp knuckle Fabrics  22 - 41  according to various embodiments of our invention, including the PVI, PVDI, and PVDI-KR for each of the fabrics. Notably, these structuring fabrics have a wider range of characteristics than the structuring fabrics described above. For example, contact lengths of the warp knuckles of Fabrics  22 - 41  ranged from about 2.2 mm to about 5.6 mm. In further embodiments of our invention, however, the contact lengths of the warp knuckles may range from about 2.2 mm to about 7.5 mm. Note that in the case of Fabrics  22 - 37  and  41 , the pocket depths were determined by forming a handsheet on the fabrics and then determining the size of domes on the handsheet (the size of the domes corresponding to the size of the pockets, as described above). The pocket depths for Fabrics  38 - 40  were determined using techniques set forth in the aforementioned fabric characterization patents. 
     Further trials were conducted to evaluate properties of absorbent sheets according to embodiments of our invention. In these trials, the Fabrics  27  and  38  were used. For these trials, a papermaking machine having the general configuration shown in  FIG. 1  was used with a process as described above. Parameters used to produce the basesheets for these trials are shown in TABLE 3. Note that an indication of a varying rate means that the process variable was varied in different trial runs. 
                             TABLE 3               Process Variable   Location   Rate                  Furnish   Lighthouse Recycled Fibers   Homogeneous       Refiner   Stock   No load (22 hp)       Temporary Wet   N/A   0       Strength Resin               Starch:   Static mixers   As needed       REDIBOND ™ 5330A               Crepe Roll Load   Crepe Roll   30-40 PLI       Fabric Crepe   Crepe Roll   varying 25%-35%       Reel Crepe   Reel   2-4%       Molding Box Vacuum   Molding Box   Maximum

     Pictures of the absorbent sheets made with Fabric  27  are shown in  FIGS. 11A-11E  and pictures of the absorbent sheets made with Fabric  38  are shown in  FIGS. 12A-12E . As is apparent from  FIGS. 11A-11E and 12A-12E , the domed regions of the absorbent sheets include a plurality of indented bars like the absorbent sheets described above. And, also like the absorbent sheets described above, the absorbent sheets made with Fabrics  27  and  38  include bilaterally staggered domed regions that result in substantially continuous, stepped lines in the MD of the absorbent sheets, and substantially continuous, stepped connecting regions between the domed regions. 
     The profiles of the domed regions in the basesheets made from Fabrics  27  and  38  were determined using laser scanning, in the same manner that the profiles were determined in the absorbent sheets described above. It was found that the domed regions in the basesheets made with Fabric  27  had 4 to 7 indented bars, with there being an average (mean) of 5.2 indented bars per domed region. The indented bars of domed regions extended from about 132 to about 274 microns below the tops of adjacent areas of the domed regions, with an average (mean) depth of about 190 microns. Further, the domed regions extended about 4.5 mm in the MD of the basesheets. 
     The domed regions in the basesheets made with Fabric  38  had 4 to 8 indented bars, with there being an average (mean) of 6.29 indented bars per domed region. The indented bars of domed regions in the basesheets made with Fabric  38  extended from about 46 to about 159 microns below the tops of adjacent areas of the domed regions, with an average (mean) depth of about 88 microns. Further, the domed regions extended about 3 mm in the MD of the basesheets. 
     Because the extended MD direction domed regions in the basesheets made with Fabrics  27  and  38  include a plurality of indented bars, it follows that the basesheets will have similar beneficial properties stemming from the configuration of the domed regions as the absorbent sheets described above. For example, the basesheets made with Fabrics  27  and  38  will be softer to the touch compared to basesheets made with fabrics not having long warp knuckles. 
     Other properties of the basesheets made with Fabrics  27  and  38  were compared to the properties of basesheets made with shorter knuckle fabrics. Specifically, the caliper and pocket depth were compared for uncalendered basesheets made with the different fabrics. The caliper was measured using standard techniques that are well known in the art. It was found that the caliper of the basesheets made with Fabric  27  varied from about 80 mils/8 sheets to about 110 mils/8 sheets, while the basesheets made with Fabric  38  varied from about 80 mils/8 sheets to about 90 mils/8 sheets. Both of these ranges of caliper are very comparable, if not better than, the about 60 to about 93 mils/8 sheets caliper that was found in the basesheets made with shorter warp yarn knuckle fabrics under similar process conditions. 
     The depths of the domed regions were measured using a topographical profile scan of the air side (i.e, the side of the basesheets that contacts the structuring fabric during the papermaking process) of the basesheets to determine the depths of the lowest points of domed regions below the Yankee side surface. The depths of the domed regions in the basesheets made using Fabric  27  ranged from about 500 microns to about 675 microns, while the depths of the domed regions in the basesheets made using Fabric  38  ranged from about 400 microns to about 475 microns. These domed regions were comparable to, if not greater than, the depths of the domed regions in basesheets made from the structuring fabrics having shorter warp yarn knuckles. This comparability of the depths of domed regions is consistent with the finding that the basesheets made with the long warp yarn structuring fabrics have comparable caliper to the basesheets made with the shorter warp yarn structuring fabrics inasmuch as the depth of domed regions is directly related to the caliper of an absorbent sheet. 
     The characteristics of further long warp yarn knuckle fabrics according to our invention are labeled as Fabrics  42 - 44  in  FIG. 13 . Also shown in  FIG. 13  is a conventional Fabric  45  that does not include long warp yarn knuckles. Further characteristics of Fabric  42  are given in  FIG. 14 , which shows the profile along one of the warp yarns of the fabric. As can be seen in these figures, Fabric  42  has several notable features in addition to including long warp yarn knuckles. One feature is that the pockets are long and deep, as reflected in the PVI related parameters indicated in  FIG. 13 . As can also be seen in the pressure imprint of Fabric  42  shown in  FIG. 13 , another notable feature of this fabric is that the CD yarns are entirely located below the plane of the knuckles in the MD yarns such that there are no CD knuckles at the top surface of the fabric. Because there are no CD knuckles, there is a gradual slope to the warp yarns in the z-direction, the details of which are shown in the profile scan in  FIG. 14 . As indicated in this figure, the warp yarns have a slope of about 200 μm/mm from the lowest point where the warp yarns pass under a CD yarn to the top of the adjacent warp knuckle. More generally speaking, the warp yarns are angled from about 11 degrees relative to a plane that Fabric  42  moves along during the creping operation. It is believed that this gradual slope of the warp yarns allows the fibers in a web being pressed to Fabric  42  to only slightly pile up on the sloped portion of the warp yarn before some of the fibers slip up over the top of the adjacent knuckle. The gradual slope of the warp yarns in Fabric  42  thereby creates less of an abrupt stop for the fibers of the web and less densification of the fibers as compared to other fabrics where the warp yarns have a steeper slope that is contacted by the web. 
     Fabrics  42  and  43  both have higher PVDI-KR values, and these values in conjunction with the PVDI-KR values of the other structuring fabrics described herein are generally indicative of the range of PVDI-KR values that can be found in embodiments of our invention. Further, structuring fabrics with even higher PVDI-KR values, for example, up to about 250, could also be used. 
     In order to evaluate the properties of Fabric  42 , a series of trials was conducted with this fabric and with Fabric  45  for comparison. In these trials, a papermaking machine having the general configuration shown in  FIG. 1  was used to form absorbent towel basesheets. The non-TAD process described generally above (and specifically set forth in the aforementioned &#39;563 patent) was used, wherein the web was dewatered to the point that it had a consistency of about 40 to about 43 percent when transferred onto the top side of the structuring fabric (i.e., Fabric  42  or  45 ) at the creping nip. Other particular parameters of these trails were as shown in TABLE 4.

     The results of the trials shown in TABLES 5-9 demonstrate that Fabric  42  can be used to produce basesheets having an outstanding combination of properties, particularly caliper and absorbency. Without being bound by theory, we believe that these results stem, in part, from the configuration of knuckles and pockets in Fabric  42 . Specifically, the configuration of Fabric  42  provides for a highly efficient creping operation due to the aspect ratio of the pockets (i.e., the length of the pockets in the MD versus the width of the pockets in the CD), the pockets being deep, and the pockets being formed in long, near continuous lines in the MD. These properties of the pockets allow for great fiber “mobility,” which is a condition where the wet compressed web is subjected to mechanical forces that create localized basis weight movement. Moreover, during the creping process, the cellulose fibers in the web are subjected to various localized forces (e.g., pushed, pulled, bent, delaminated), and subsequently become more separated from each other. In other words, the fibers become de-bonded and result in a lower modulus for the product. The web therefore has better vacuum “moldability,” which leads to greater caliper and a more open structure that provides for greater absorption. 
     The fiber mobility provided for with the pocket configuration of Fabric  42  can be seen in the results shown in  FIGS. 15 and 16 . These figures compare the caliper, SAT capacity, and void volume at the various crepe levels used in the trials.  FIGS. 15 and 16  show that, even in the trials with Fabric  42  where no vacuum molding was used, the caliper and SAT capacity increased with the increasing fabric crepe level. As there was no vacuum molding, it follows that these increases in caliper and SAT capacity are directly related to fiber mobility in Fabric  42 .  FIGS. 15 and 16  also demonstrate that a high amount of caliper and SAT capacity are achieved using Fabric  42 —in the trials where vacuum molding is used, at each creping level the caliper and SAT capacity of the basesheets made with Fabric  42  were much greater than the caliper and SAT capacity of the basesheets made with Fabric  45 . 
     The fiber moldability provided by Fabric  42  can also be seen in the results shown in  FIGS. 15 and 16 . Specifically, the differences between the caliper and SAT capacity in the trials with no vacuum molding and the trials with vacuum molding demonstrates that the fibers in the web are highly moldable on Fabric  42 . As will be discussed below, vacuum molding draws out the fibers in the regions of the web formed in the pockets of Fiber  42 . The large fiber moldability means that the fibers are highly drawn out in this molding operation, which leads to the increased caliper and SAT capacity in the resulting product. 
       FIG. 19  also evidences that greater fiber mobility is achieved with Fabric  42  by comparing the void volume of the basesheets from the trials at the fabric crepe levels. The absorbency of a sheet is directly related to void volume, which is essentially a measure of the space between the cellulose fibers. Void volume is measured by the procedure set forth in the aforementioned U.S. Pat. No. 7,399,378. As shown in  FIG. 19 , the void volume increased with the increasing fabric crepe in the trials using Fabric  42  where no vacuum molding was used. This indicates that the cellulose fibers were more separated from each other (i.e., de-bonded, with a lower resulting modulus) at each fabric crepe level in order to produce the additional void volume.  FIG. 19  further demonstrates that, when vacuum molding is used, Fabric  42  produces basesheets with more void volume than the conventional Fabric  45  at each fabric crepe level. 
     The fiber mobility when using Fabric  42  can also be seen in  FIGS. 20A, 20B, 21A, and 21B , which are soft x-ray images of basesheets made using Fabric  42 . As will be appreciated by those skilled in the art, soft x-ray imaging is a high-resolution technique that can be used for gauging mass uniformity in paper. The basesheets in  FIGS. 20A and 20B  where made with an 8 percent fabric crepe, whereas the basesheets in  FIGS. 21A and 21B  were made with a 25 percent fabric crepe.  FIGS. 20A and 21A  show fiber movement at a more “macro” level, with the images showing an area of 26.5 mm by 21.2 mm. Wave-like patterns of less mass (corresponding to the lighter regions in the images) can be seen with the higher fabric crepe ( FIG. 21A ), but regions of less mass are not readily seen with the lower fabric crepe ( FIG. 20A ).  FIGS. 20B and 21B  show the fiber movement at a more “micro” level, with the images showing an area of 13.2 mm by 10.6 mm. The cellulose fibers can clearly be seen as more distanced from each other and pulled apart with the higher fabric crepe ( FIG. 21B ) than with the lower fiber crepe ( FIG. 20B ). Collectively, the soft x-ray images further confirm that Fabric  42  provides for greater fiber mobility with the higher localized mass movement being seen at the higher fabric crepe level than at the lower fabric crepe level. 
       FIGS. 17 and 18 , and also  FIG. 19 , show the results of the trials in terms of the furnish. Specifically, these figures show that Fabric  42  can produce comparable amounts of caliper, SAT capacity, and void volume when using the non-premium furnish as well as with the premium furnish. This is a very beneficial result as it demonstrates that the Fabric  42  can achieve outstanding results with a lower cost, non-premium furnish. 
     Because Fabric  42  has extra-long warp yarn knuckles, as with the other extra-long warp yarn knuckle fabrics described above, the products made with Fabric  42  may have multiple indented bars extending in a CD direction. The indented bars are again the result of folds being created in the areas of the web that are moved into the pockets of the structuring fabric. In the case of Fabric  42 , it is believed that the aspect ratio of the length of the knuckles and the length across the pocket even further enhances the formation of the folds/indented bars. This is because the web is semi-restrained on the long warp knuckles while being more mobile within the pockets of Fabric  42 . The result is that the web can buckle or fold at multiple places along each pocket, which in turn leads to the CD indented bars seen in the products. 
     The indented bars formed in absorbent sheets made from Fabric  42  can be seen in  FIGS. 22A-22E . These figures are images of the air-side of products made with Fabric  42  at different fabric creping levels but with no vacuum molding. The MD is in the vertical direction in all of these figures. Notably, instead of having sharply defined dome regions like the products described above, the products in  FIGS. 22A-22E  are characterized by having parallel and near-continuous lines of projected regions substantially extending in the MD, with each of the extended projected regions including a plurality of indented bars extending across the projected regions in a substantially CD of the absorbent sheet. These projected regions correspond to lines of pockets extending in the MD of Fabric  42 . Between the projected regions are connecting regions that also extend substantially in the MD. The connecting regions correspond to the long warp yarn knuckles of Fabric  42 . 
     The product in  FIG. 22A  was made with a fabric crepe of 25%. In this product, the indented bars are very distinct. It is believed that this pattern of indented bars is the result of the fiber network on Fabric  42  experiencing a wide range of forces during the creping process, including in-plane compression, tension, bending, and buckling. All of these forces will contribute to the fiber mobility and fiber moldability, as discussed above. And, as a result of the near continuous nature of the projected regions extending in the MD, the enhanced fiber mobility and fiber moldability can take place in a near continuous manner along the MD. 
       FIGS. 22B-22E  show the configuration of products with less fabric creping as compared to the product shown in  FIG. 22A . In  FIG. 22B , the fabric crepe level used to form the depicted product was 15%, in  FIG. 22C  the fabric crepe level was 10%, in  FIG. 22D  the fabric crepe level was 8%, and in  FIG. 22E  the fabric crepe level was 3%. As would be expected, the amplitude of the folds/indented bars can be seen to decrease with the decreasing fabric crepe level. However, it is notable that the frequency of the indented bars remains about the same through the fabric crepe levels. This indicates that the web is buckling/folding in the same locations relative to the knuckles and pockets in Fabric  42  regardless of fabric crepe level being used. Thus, beneficial properties stemming from the formation of folds/indented bars can be found even at lower fabric crepe levels. 
     In sum,  FIGS. 22A-22E  show that the high pocket aspect ratio of Fabric  42  has the ability to uniformly exert decompacting energy to the web such that fiber mobility and fiber moldability are promoted over a wide fabric creping range. And, this fiber mobility and fiber moldability is a very significant factor in the outstanding properties, such as caliper and SAT capacity, found in the absorbent sheets made with Fabric  42 . 
       FIGS. 23A-24B  are scanning electron microscopy images of the air sides of a product made with Fabric  42  ( FIGS. 23A and 24A ) and a comparison product made with Fabric  45  ( FIGS. 23B and 24B ). In these cases, the products were made with 30% fabric crepe and maximum vacuum molding. The center regions of the images in  FIGS. 23A and 23B  show areas made in the pockets of the respective fabrics, with areas surrounding the center regions corresponding to regions formed on knuckles of the respective fabrics. The cross sections shown in  FIGS. 24A and 24B  extend substantially along the MD, with an extended projected region of the Fabric  42  product being seen in  FIG. 24A  and with multiple domes (as formed in multiple pockets) being seen in the Fabric  45  product shown in  FIG. 24B . It can very clearly be seen that the fibers in the product made with Fabric  42  are much less densely packed than the cellulose fibers in the product made with Fabric  45 . That is, the center dome regions in the Fabric  45  product are highly dense—as dense, if not more dense, than the connecting region surrounding the pocket region in the Fabric  42  product. Moreover,  FIGS. 24A and 24B  show the fibers to be much looser, i.e., less dense, in the Fabric  42  product than in the Fabric  45  product, with distinct fibers springing out from the Fabric  42  product structure in  FIG. 24A .  FIGS. 23A-24B  thereby further confirm that that Fabric  42  provides for a large amount of fiber mobility and fiber moldability creping process, which in turn results in regions of significantly reduced density in the absorbent sheet products made with the fabric. The reduced density regions provide for greater absorbency in the products. Further, the reduced density regions provide for more caliper as the sheet becomes more “puffed out” in the reduced density regions. Still further, the puffy, less dense regions will result in the product feeling softer to the touch. 
     Further trials were conducted using Fabric  42  to evaluate properties of converted towel products according to embodiments of our invention. For these trials, the same conditions were used as in the trials described in conjunction with TABLES 4 and 5. The basesheets were then converted to two-ply paper towel. TABLE 10 shows the converting specifications for these trials. Properties of products made in these trials are shown in TABLES 11-13.

     Note that Trial  22  only formed a one-ply product, but was otherwise converted in the same manner as the other trials. 
     The results shown in TABLES 11-13 demonstrate the excellent properties that can be achieved using a long warp warn knuckle fabric according to our invention. For example, the final products made with Fabric  42  had higher caliper and higher SAT capacity than the comparison products made with Fabric  45 . Further, the results in TABLES 11-13 demonstrate that very comparable products can be made with Fabric  42  regardless of whether a premium or a non-premium furnish is used. 
     Based on properties of the products made in the trials described herein, it is clear that the long warp yarn knuckle structuring fabrics described herein can be used in methods that provide products having outstanding combinations of properties. For example, the long warp yarn knuckle structuring fabrics described herein can be used in conjunction with the non-TAD process described generally above and specifically set forth in the aforementioned &#39;563 patent, (wherein the papermaking furnish is compactively dewatered before creping) to form an absorbent sheet that has SAT capacities of at least about 9.5 g/g and at least about 500 g/m 2 . Further, this absorbent sheet can be formed in the method while using a creping ratio of less than about 25%. Even further, the method and long warp yarn knuckle structuring fabrics can be used to produce an absorbent sheet that has SAT capacities of at least about at least about 10.0 g/g and at least about 500 g/m 2 , has a basis weight of less than about 30 lbs/ream, and a caliper 220 mils/8 sheets. We believe that this type of method has never created such an absorbent sheet before. 
     Further absorbent towel basesheets were made in trials with Fabrics  42  and  45 . These trials were conducted on a papermaking machine having a configuration as shown in  FIG. 1 , using the non-TAD process described generally above (and specifically set forth in the aforementioned &#39;563 patent), and the parameters for these trials were the same as those shown and described in TABLE 4 above. The results of these trials are shown in TABLES 14-16 below.

     As with the previously-described trials, the absorbent sheets made using Fabric  42  in the trials shown in TABLES 14-16 have an outstanding combination of properties, in particular, outstanding caliper and absorbency. 
       FIGS. 25A and 25B  indicate characteristics of further structuring fabrics according to embodiments of our invention. Like the fabrics discussed above, the Fabrics  46 - 52  shown in  FIGS. 25A and 25B  have long warp yarn knuckles, which range from about 2.4 mm to about 5.7 mm. Also like fabrics discussed above, Fabric  46 - 52  have high PVDI-KR values, ranging from about 41 to about 123. 
     The Fabrics  46 - 52  also demonstrate another aspect of our invention related to positioning of the knuckles on the web-contacting surface of structuring fabrics. As can be seen from the pressure imprint pictures, the knuckles in Fabrics  46 - 52  are positioned relative to each other such that straight lines can be drawn through the centers of a plurality of the knuckles. One such line L 1  is shown in  FIG. 26 , which is a detailed view of the pressure imprint of Fabric  50 . The angle α of line L 1  relative to a line MDL that runs along the MD of the fabric is about 15°. In other structuring fabrics according to embodiments of our invention, warp yarn knuckle lines can be between about 10° to about 30° relative to an MD line, and in more specific embodiments, the warp yarn knuckle lines can be between about 10° to about 20° relative to an MD line. The angles of the warp yarn knuckle lines for Fabrics  46 - 52  are given in  FIGS. 25A and 25B . It should also be noted that some of the other fabrics described herein include similar angled lines of warp yarn knuckles, including, for example, Fabric  42  shown in  FIG. 13 . 
     We have found that paper products made with structuring fabrics having angled warp yarn knuckle lines, such as those shown in Fabrics  42  and  46 - 52 , have exceptional properties. Without being bound by theory, we believe that these exceptional properties stem from a large amount of fiber mobility that is provided for by structuring fabrics having angled warp yarn knuckle lines. 
     This fiber mobility of a structuring fabric that has angled warp yarn knuckle lines is demonstrated in  FIG. 27A , and this fiber mobility can be compared to other structuring fabric configurations as shown in  FIGS. 27B and 27C . The fibers are moved to the fold formations  4002  and  5002  shown in these figures, for example, during a creping operation, such as when the web  116  is transferred from the backing roll  108  to the structuring fabric  112  in the creping nip  120 , as shown in  FIG. 1  and as described above.  FIG. 27B  illustrates the case of an MD knuckle  4000  in a structuring fabric. The cellulose fibers of the web are stacked in dense folds  4002  against an edge  4004  of the knuckle  4000  during the creping process, thereby creating a localized densification zone  4006  adjacent to the knuckle  4000 . Such localized densification of fibers would also occur at other MD knuckles in the structuring fabric.  FIG. 27C  shows how a CD knuckle  5000  of a structuring fabric also has a localized densification zone as a result of web folds  5002  piling up against an edge  5004  of the knuckle  5000 . 
     In contrast, the knuckles  6000  in the angled warp yarn lines shown in  FIG. 27A  result in a much different fold formations  6002  than the fold formations  4002  and  5002  illustrated in  FIGS. 27B and 27C , respectively. With the angled warp yarn knuckle lines, a strain field arises though the combination of the movement of the knuckles  6000  and the adhesion of the web  116  to the backing roll  108 . The strain field is localized to the pocket regions between the knuckles  6000 . The strain field arises because of the creping ratio speed differential in the web transfer from the transfer surface to the structuring fabric: in the creping nip, portions of the web are pulled in a downstream direction by the faster moving transfer surface, while other portions of the web are effectively held up by the slower moving knuckles  6000 . During the creping operation, the web is, for example, 40% to 45% solids, which means that the web will behave in a substantially viscous manner. Thus, fibers of the web in the strain field can be permanently repositioned relative to each other—after exiting the creping operation, the fibers do not recover to their relative positioning before they entered the strain field. This fiber mobilization in the strain field increases the fiber-fiber distance, and thereby weakens the bonds between the fibers so that the web can be molded more easily. The result is that the fibers are distributed in curved folds in the pockets between the knuckles  6000 . The curved folds are an indication that fiber mobilizing work has occurred in the pockets. And, as indicated by the results of the trials described above, there are significant improvements in absorbency and softness when fiber mobilization leading to the curved folds is achieved, as evidence, for example, by the SAT and void volumes of the absorbent sheets made by Fabric  42 . 
     The curved folds are shaped such that apexes  6003  of the curved folds are positioned downstream in the MD, and ends of the curved folds are offset in the MD, with ends  6007  of the curved folds being positioned upstream in the MD relative to the other ends  6009  of the curved folds. In comparison, the curved folds shown in  FIG. 27A  are significantly less dense than the piles of fibers formed at the edges of MD and CD knuckles in structuring fabrics not having angled warp yarn lines shown in  FIGS. 27B and 27C . And, we believe that absorbent sheets have greatly improved softness and absorbency because of the reduced densification of the curved folds, which in turn relates to the fiber mobilization discussed above. 
     The shapes of the curved folds are also related to the distances D 1  between the knuckles  6000 . As will be appreciated by those skilled in the art, if the knuckles  6000  are too close, there will not be enough room in the pocket between the knuckles  6000  for the fibers to move into the less dense, curved folds. On the other hand, if the knuckles are too far apart, many of the fibers will not be subjected to the strain field action of the faster moving transfer surface and the slower moving knuckles, and thus, fewer, less pronounced, curved folds may be formed in the web and the resultant absorbent sheet. With these considerations in mind, in embodiments of our invention the distances D 1  between the centers of two adjacent knuckles  6000  in different warp yarn knuckle lines can be about 1.5 mm to about 4.0 mm. In a specific embodiment, the distances D 1  are about 2.0 mm. With the 2.0 mm distance between the knuckles  6000 , there is about 1.5 mm of room in the pocket region between the two adjacent knuckles  6000 . 
       FIGS. 28A-28E  are photographs of absorbent basesheets made with a structuring fabric having angled warp yarn knuckle lines, with a papermaking machine having the general configuration shown in  FIG. 1 , using the non-TAD process described generally above (and specifically set forth in the aforementioned &#39;563 patent), and with the parameters shown in TABLE 4 above. Different creping ratios (i.e., fabric crepe %) and different molding box vacuums were used for each of the basesheets shown in  FIGS. 28A-28E . Specifically, the basesheet in  FIG. 28A  was made with a 25% crepe ratio and a molding box vacuum of 2 in. Hg, the basesheet in  FIG. 28B  was made with a 25% crepe ratio and a molding box vacuum of 8 in. Hg, the basesheet in  FIG. 28C  was made with a 30% crepe ratio and a molding box vacuum of 10 in. Hg, and the basesheet in  FIG. 28D  was made with a 25% crepe ratio and a molding box vacuum of 8 in. Hg. The basesheet shown in  FIG. 28E  was made with a 20% crepe ratio, but no molding box vacuum. Note, as there is no vacuum molding used in the production of the basesheet shown in  FIG. 28E , the basesheet is also indicative of the structure of web following the creping operation in the papermaking process. That is, the web in the papermaking process would have the same general curved fold formations as the basesheet product shown in  FIG. 28E . It should also be noted that different creping ratios may be used in conjunction with structuring fabrics having angled warp yarn knuckle lines in other embodiments of our invention. In some embodiments, the creping ratio used with an angled warp yarn knuckle line fabric is between about 3% and about 100%, in more specific embodiments, the creping ratio is between about 3% to about 50%, in even more specific embodiment, the creping ratio is between about 5% and 30%. 
     Curved folds can clearly be seen in the projected regions of the basesheets shown in  FIGS. 28A-28E . In these figures, the MD of the sheets is in the vertical (i.e, up and down) direction, with the upstream side of the sheets being at the top of the pictures and the downstream side of the sheets being at the bottom of the figures. In  FIG. 28A  some of the curved folds have been marked with dotted lines. As a result of the angled warp yarn knuckle lines, the ends of the curved shapes are unsymmetrical: one end of the curved folds is positioned more downstream than the other end of the curved folds. The curved folds extend between these two ends to an apex that is at a downstream most part of the curved folds. And, the ends of the curved folds are positioned adjacent to connecting regions, which correspond to the knuckles of the fabric. 
     Curved folds can also be seen in the absorbent sheets shown in  FIGS. 22A and 22E . As previously noted, the absorbent sheets in these figures were formed using Fabric  42 , which includes angled lines of warp yarn knuckles. Further, the curved folds can be seen in the soft x-ray images shown in  FIGS. 21A and 21B . 
       FIGS. 28A-28E  also show that multiple curved folds are formed in each of the projected regions. The multiple curved folds are a result of the extended length in the MD direction of the pockets in which the domed regions are formed, and, thus, the curved folds are also related to the length of the warp yarn knuckles. As the web is transferred to the structuring fabric in the process of making absorbent sheets using a creping operation (as discussed above), multiple folds are created in the structure of the web within the pockets. Thus, in the same manner that multiple intended bars are formed in each of the projected regions of the absorbent sheets in the embodiments discussed above, multiple indented bars are formed between the multiple curved folds in the projected regions of the absorbent sheets shown in  FIGS. 28A-28E . Such indented bars can be seen between the curved folds in the absorbent sheets shown in  FIGS. 28A-28E . 
     The connecting regions connect the projected regions having the curved folds can also be seen in the photographs of the basesheets shown in  FIGS. 28A-28E . These connecting regions largely correspond to the parts of the sheet that were formed on the knuckles of fabrics used to make these sheets, as well as parts of the sheet that were formed in regions adjacent to the knuckles and pockets. An aspect of the connecting regions of the basesheet according to our invention is highlighted in  FIG. 28A , wherein regions adjacent to upstream ends of the projected regions are circled. It can be seen that the sheet has folded in these circled regions. These folds are formed because of a z-direction slope in the warp yarns, and lack of CD knuckles, as discussed above. In particular, the web can slide into these parts of the connecting regions in the papermaking process, thereby creating the folds. The folds in the connecting regions act to further reduce the density of the fibers, thereby further improving properties of the absorbent sheets. 
     Based on photographs such as those shown in  FIGS. 28A-28E , a radius of curvature for the curve folds can be calculated. Specifically, circles can be drawn such that arcs of the circles align with the curved folds. As is evident from the photographs shown in  FIGS. 28A-28E , the leading (downstream) edges of the curved folds are most prominent, and, thus, it is easiest to draw the circles such that the arcs align with the leading edges.  FIG. 29  is the same photograph as  FIG. 28A , additionally showing circles with arcs aligned with the leading edges of some of the curved folds. From such circles, and using the scale of the photograph, an average radius of curvature for the curved folds may easily be calculated. In embodiments of our invention, we have found that the radius of curvature for the curved folds averages about 1.2 mm, with the radiuses ranging between about 0.5 mm and about 2.0 mm. 
     As discussed above, the curved folds are formed as a result of a localized strain field that arises when a creping operation is performed with an angled warp yarn knuckle fabric according to our invention. For a given absorbent sheet, a normalized fold curvature ratio can be calculated as the radius of curvature for a curved fold divided by a radius of a circle drawn within the projected regions. The lower the normalized fold curvature ratio, the more effective the strain field has been to curve the folds. And, we believe that with a more effectively formed fold curvature, the absorbency and softness of the absorbent sheet are improved. 
     An example of calculating the normalized fold curvature ratio for absorbent sheet will now be described with reference to  FIGS. 30A and 30B . An absorbent sheet according to our invention is shown in  FIG. 30A , and a commercially-available comparison absorbent sheet is shown in  FIG. 30B . In  FIG. 30A , an arc has been drawn to match one of the curved folds. From this and other similarly drawn arcs, the average radius of curvature for the curved folds may be calculated, as discussed above. Similarly, an arc has been drawn in  FIG. 30B  to match a slight curvature that can be seen in the fold formations, and an average radius for this absorbent sheet may thereby be calculated from this and similar arcs. The full circles in  FIGS. 30A and 30B  have been drawn within the projected regions, with opposite points of the circles aligning with points on opposite sides of the projected regions in which the curved fold formations appear. The circles are the maximum size that can be fit within the projected regions, and the radiuses of these circles are therefore half of the distance across the projected regions in the CD of the absorbent sheet. The normalized fold curvature ratio can then be calculated for the absorbent sheets shown in  FIGS. 30A and 30B  as the ratio of the calculated average radius of curvature and the radius of curvature for the maximum circle size within the projected regions. For the absorbent sheet according to our invention shown in  FIG. 30A , the calculated average radius of curvature is about 1.2 mm, and the normalized fold curvature ratio is about 1.9. On the other hand, for the comparison absorbent sheet shown in  FIG. 30B , the calculated average radius of curvature is about 4.55 and the normalized fold curvature ratio is about 4.5. Thus, it is evident that the absorbent sheet according to our invention has both more of curvature in its fold formation than the comparison sheet, and that the curvature is much closer to the maximum curvature that was possible in the formation of the absorbent sheet. 
     In embodiments of our invention, the normalized fold curvature ratio is less than about 4, and more particularly, from about 0.5 to about 4. In more specific embodiments, the normalized fold curvature ratio is from about 1 to about 3. As evidence by the absorbent sheet shown in  FIG. 30A , embodiments of our invention may have a specific normalized fold curvature ratio around about 2. When the normalized fold curvature ratio is in these ranges, we believe that a significant amount of fiber mobilization has occurred for the given fabric. Thus, as also discussed above, the fiber mobilization leads to better properties in the paper product, such as good absorbency.
