Single ply creped throughair dried non-wood tissue

Abstract

Tissue products that possess a balance of strength, durability, and softness are produced by blending hesperaloe and wood pulp fibers to create a wet tissue web, which is subsequently dried and creped. Despite being creped and having hesperaloe fibers on its outer surface, the tissue product maintains low lint levels, with a Slough of less than 4.00 mg. The creped tissue webs may be converted into single-ply tissue products, particularly rolled bath tissue products, that exhibit good strength characteristics, such as a geometric mean tensile strength of 700 g / 3" or greater, and durability, such as a geometric mean tear strength of 8.0 gf or greater. Despite having good strength and durability the tissue products are flexible, indicated by a Stiffness Index of less than 6.0.

Description

[0001]SINGLE PLY CREPED THROUGHAIR DRIED NON-WOOD TISSUE BACKGROUND OF THE DISCLOSURE Uncreped throughdried tissue sheet manufacturing methods are capable of extremely high production rates when producing tissue sheets. Softness is achieved by proper selection of fibers, layering, rush transfer, high-topography throughdrying fabrics and heavy calendaring to produce the resulting tissue sheet. Much of the bulk realized on the tissue machine is lost during calendaring. By comparison, conventional creped throughdried tissue sheets are generally soft but lack the bulk, acceptable lint levels and processing flexibility associated with uncreped throughdried processes. In the manufacture of rolled, creped tissue products such as bathroom tissue and paper towels, a wide variety of product characteristics must be given attention in order to provide a final tissue product with the appropriate blend of attributes suitable for the product's intended purposes. Improving the softness of tissues is a continuing objective in tissue manufacture, especially for premium products. Softness, however, is a perceived property of tissues comprising many factors including thickness and smoothness. Generally, higher softness is perceived with high basis weight webs due to the increased thickness of the tissue sheet. These properties however, often come at the expense of increased tensile strength and stiffness, particularly when using non-wood fibers. Thus, there remains a need for creped tissue products, particularly products containing non-wood fibers, have a high degree of surface softness while maintaining good sheet bulk and basis weight. It is also broadly known in the art that increases to surface feel and overall softness achieved by creping often comes at the expense of increased surface lint and slough. This particularly true when non-wood fibers are used in the manufacture of creped tissue products. For this reason, creped tissue products are often formed from layer tissue structures where the non-wood fibers are disposed in interiors layers, away from the outermost surface of the structure, to minimize lint and slough. Thus, there remains a need in the art for creped tissue products having reduced lint and slough, particularly when using non-wood fibers. SUMMARY OF THE DISCLOSURE The present inventors have successfully used non-wood pulps, particularly pulps produced from hesperaloe, to produce tissue products having softness, strength and bulk comparable or better than that achieved using conventional wood pulp. To produce the instant tissue products the inventors have successfully moderated the changes in strength and stiffness typically associated with substituting conventional wood papermaking fibers, such as NSWK, with non-wood fibers. These changes have generally been achieved by a variety of means, including the use of hesperaloe pulps produced by high yield pulping processes, particularly processes involving mechanical separation of individual fibers and the reduction of fiber length and subsequent cleaning of the pulp to remove epidermal debris. The removal of epidermal debris makes the hesperaloe pulps particularly well suited to the manufacture of creped tissue products. Accordingly, in certain instances, the present invention provides a creped tissue product having a Slough less than 4.00 mg, such as less than about 3.80 mg, such as less than about 3.60 mg, such as from about 2.00 to about 4.00 mg. Additionally, the use of high yield pulping processes, particularly processes involving mechanical separation of individual fibers without the addition of chemicals, yields non-wood pulps that develop only a modest degree of tensile strength in-use. Thus, the tissue products of the present invention generally have a moderate degree of tensile strength. For example, in certain instances, the tissue products of the present invention may comprise a single creped tissue ply and have a geometric mean tensile (GMT) greater than about 700 g / 3”, such as from about 700 to about 1,500 g / 3”, such as from about 800 to about 1,200 g / 3”. At the foregoing tensile strengths, the tissue products may have a high degree of softness (measured using a Tissue Softness Analyzer as described in the Test Methods below) such as a TS7 value less than about 10.0. such as less than about 9.75, such as less than about 9.50, such as less than about 9.25, such as from about 8.0 to about 10.0. In certain instances, the tissue products may comprise a single ply creped tissue ply having at least about 10 wt% high yield hersperaloe pulp, a GMT greater than about 700 g / 3”, such as from about 700 to about 1,500 g / 3”, such as from about 800 to about 1,200 g / 3”, and a TS7 from about 8.00 to about 10.00. Surprisingly, the improvement in strength and softness may be achieved by distributing the hesperaloe pulp fibers throughout the entire creped tissue ply. Thus, in certain instances, the present invention provides tissue products comprising at least one creped tissue ply comprising a blend of hesperaloe pulp fibers and wood pulp fibers. In this manner the tissue web or ply may be unstratified and the hesperaloe pulp fibers may be distributed throughout the ply and may be brought into contact with a user’s skin in-use. Despite having hesperaloe pulp fibers disposed in the outer surface, the inventive tissue products have a high degree of softness. For example, a creped single ply tissue product may comprise a blend of high yield hersperaloe pulp fibers and wood pulp fibers and have a TS7 value from about 8.0 to about 10.0 and a GMT from about 700 to about 1,500 g / 3”. Surprisingly, despite having hesperaloe pulp fibers disposed in the outer surface, the foregoing products may have a Slough less than 4.00 mg, such as less than about 3.80 mg, such as less than about 3.60 mg, such as from about 2.00 to about 4.00 mg. In other instances, the creped tissue products may have a Stiffness Index about 7.50 or less, such as less than about 7.00, such as less than about 6.50, such as from about 4.00 to about 10.0. In this manner the inventive tissue products have a relatively low degree of stiffness, which combined with a high degree of softness, provide the tissue products with a good handfeel. Surprisingly, the low levels of stiffness are achievable even when hesperaloe pulp fibers are present throughout the web, rather than being selectively disposed in a single layer. In this manner hesperaloe pulp fibers may be present on the product surface, where they are brought into contact with a user’s skin, without stiffening the product. Furthermore, because the hesperaloe pulps preferably have a low degree of epidermal debris, the pulp fibers may be present along the outer surface without causing the surface to be overly rough or abrasive. In still other instances, the present invention provides tissue products having relatively moderate amounts of long average fiber length kraft fibers, such as softwood kraft pulp fibers, or are substantially free from long average fiber length kraft fibers. For example, the tissue products may comprise less than about 10 wt%, based upon the total weight of the tissue product, softwood kraft pulp fibers. In other instances, the tissue products of the present invention may be substantially free from softwood kraft pulp fibers, particularly NSWK. In yet other instances, the present invention provides a single ply creped tissue product comprising at least about 5 weight percent hesperaloe fiber, the tissue product having a dry burst strength greater than about 500 gf, such as greater than about 525 gf, such as greater than about 550 gf, such as from about 500 gf to about 700 gf, such as from about 500 to about 600 gf and a GM Tear greater than about 8.0 gf. The foregoing tissue products not only have good durability, such as dry burst and GM Tear, but also have low stiffness, such as a Stiffness Index less about 7.50 or less, such as less than about 7.00, such as less than about 6.50, such as from about 4.00 to about 7.5. In other instances, the present invention provides a single ply creped tissue product comprising wood pulp fibers and from about 5 to about 50 weight percent hesperaloe pulp fibers wherein the hesperaloe pulp fibers are blended with wood pulp fibers, the tissue product having a GMT from about 700 to about 1,500 g / 3” a Stiffness Index less than about 6.00 and a TS7 less than about 10.0. In still other instances, the present invention provides a crped through-air dried tissue product comprising at least about 20 weight percent high yield hesperaloe pulp fibers, the tissue product having a basis weight from about 35 to about 45 gsm, a GMT from about 700 to about 1,500 g / 3” a Stiffness Index less than about 6.00 and a TS7 less than about 10.0.

The moisture content of the handsheet should be accurately known so that the actual amount of fiber in the sample is known. This weighed sample is then diluted to a known consistency (between about 2 and about 10 mg / l) and a known volume (usually 200 ml) of the diluted pulp is sampled. This 200 ml sample is further diluted to 600 ml and placed in the analyzer. The length-weighted average fiber length is defined as the sum of the product of the number of fibers measured and the length of each fiber squared divided by the sum of the product of the number of fibers measured and the length of the fiber. Fiber lengths are generally reported in millimeters. As used herein, the term “Coarseness” generally refers to the weight per unit length of fiber, commonly having units of mg / 100 meters.

As used herein, “free of” means 0 wt%. DETAILED DESCRIPTION The present inventors have now discovered that hesperaloe pulp fibers processed by high yield pulping means, such as mechanical pulping, may overcome the limitations of kraft hesperaloe pulp fibers when incorporated into tissue products such as bath tissues, facial tissues, paper towels, industrial wipers, foodservice wipers, napkins, medical pads, and the like. The inventors have discovered that mechanical pulping of hesperaloe yields a pulp having a moderate fiber length, such as a fiber length of about 1.50 mm or greater, such as from about 1.50 to about 2.50 mm, yet a low degree of coarseness, such as less than about 10.0 mg / 100m, such as from about 3.5 to about 10.0 mg / 100 m. At the same time the pulp may have a moderate degree of tensile strength, such as a pulp Tensile Index of about 55 or less, such as from about 30 to about 55. High yield hesperaloe pulps having the foregoing properties are well suited to replace conventional wood pulps commonly used in the manufacture of tissue products, particularly softwood kraft fibers, without negatively affecting important tissue product properties such as durability, stiffness or softness. In fact, in certain instances important tissue product properties may be improved by substituting conventional wood pulp fibers with hesperaloe pulp fibers. For example, tissue products produced with high yield hesperaloe pulps have a high degree of softness, measured as TS7, and moderate degree of tensile strength. Generally, the hesperaloe pulp fibers useful in the present invention have a relatively long fiber length, such as a fiber length of about 1.50 mm or greater, such as about 1.55 mm or greater, such as about 1.60 mm or greater, such as about 1.65 mm or greater, such as about 1.70 mm or greater, such as about 1.75 mm or greater, such as from about 1.50 to about 2.50 mm, such as from about 1 .55 to about 2.00 mm. The hesperaloe pulp fibers may also have a fiber coarseness less than about 10.0 mg / 100m, such as less than about 8.0 mg / 100m, such as less than about 6.0 mg / 100m, such as from about 4.0 to about 10.0 mg / 100 m, such as from about 4.0 mg / 100 m to about 8.0 mg / 100m. The hesperaloe pulps may also have a relatively modest degree of tensile strength, such as a Tensile Index of about 55 or less, such as about 50 or less, such as about 45 or less, such as about from about 30 to about 55, such as from about 35 to about 50, such as from about 35 to about 45. In other instances, the hesperaloe pulps may have a freeness, where a higher value is indicative of pulps that are more easily dewatered, of about 500 mL or greater, such as about 510 mL or greater, such as about 525 mL or greater, such as about 550 mL or greater, such as from about 500 mL to about 600 mL. In other instances, the hesperaloe pulps may have a moderate degree of tensile strength and a low degree of fibers having a fiber length greater than 6.0 mm, which can inhibit dispersion of the pulp in water and cause stringing or clumping when the pulp is used to manufacture wet-laid fibrous products. For example, the inventive pulps may have a Tensile Index of about 55 or less, such as about 50 or less and a Very Long Fiber fraction (VLF) of about 1.0% or less, such as about 0.75% or less, such as a about 0.50% or less, such as a VLF from about 0.05% to about 1.0%. a fiber length from about 1.50 to about 2.50. In addition to having reduced tensile strengths and relatively long fiber lengths. In still other instances the hesperaloe pulps may have a high degree of brightness and / or low content of epidermis debris. Brightness and reduced debris are particularly important for pulps used in the manufacture of tissue products because of the need for a white, bright appearance and a low degree of linting. Accordingly, hesperaloe pulps useful in the present invention may have a Brightness of at least about 75%, more preferably at least about 78% and still more preferably at least about 80%. In other instances, the hesperaloe pulp may have a debris content of about 1.0 wt% or less, such as about 0.90 wt% or less, such as about 0.80 wt% or less, such as about 0.60 wt% or less. In certain instances, it may be desirable to remove substantially all of the debris from the pulp such that the pulp is substantially free from, or free from, debris. In certain preferred instances, the tissue products of the present invention are produced by a high yield pulping process High yield pulping processes useful for the manufacture of high yield hesperaloe pulps include, for example, mechanical pulp (MP), refiner mechanical pulp (RMP), pressurized refiner mechanical pulp (PRMP), thermomechanical pulp (TMP), high temperature TMP (HT-TMP), RTS-TMP, thermopulp, groundwood pulp (GW), stone groundwood pulp (SGW), pressure groundwood pulp (PGW), super pressure groundwood pulp (PGW-S), thermo groundwood pulp (TGW), thermo stone groundwood pulp (TSGW) or any modifications and combinations thereof. Preferably the high yield pulping process has a yield greater than about 60 percent, such as from about 60 to about 90 percent and more preferably from about 65 to about 90 percent. The foregoing yields generally refer to the yield of unbleached hesperaloe pulp fiber. In certain instances, high yield hesperaloe pulps may be prepared as described in mechanical pulping process where the hesperaloe biomass or bagasse is treated with an alkaline phosphate prior to or during mechanical refining, such as described in PCT Application No. PCT / US2021 / 058196, the contents of which are incorporated herein in a manner consistent with the present invention. In other instances, high yield hesperaloe pulps may be produced using a two-stage mechanical puling process where fibrillation of the hesperaloe biomass or bagasse is carried out in first mechanical pulping stage without the addition of chemicals, such alkaline peroxide chemicals, and / or other chemicals known in the art to bleach or otherwise process lignocellulosic material into pulp or precursors of pulp. Once the hesperaloe biomass or bagasse has been refined to a freeness of about 400 mL or greater, chemicals may be introduced, such as after a first mechanical pulping stage and prior to a second stage of mechanical refining. The foregoing process not only simplifies the pulping process and reduces costs, but it also improves pulp yields and the physical properties of the resulting pulp. For example, the foregoing process may be used to produce hesperaloe pulps at yields of about 80% or greater, such as about 85% or greater, such as about 90% or greater, such as yields from about 80% to about 95%. In still other instances, high yield hesperaloe pulps may be produced without the addition of chemicals, such alkaline peroxide chemicals, and / or other chemicals known in the art to bleach or otherwise process lignocellulosic material into pulp or precursors of pulp during mechanical refining of the pulp. The hesperaloe pulp may be produced using a process comprising the steps of: (a) providing a hesperaloe biomass; (b) cutting the biomass to a nominal length; (c) extracting water soluble solids from the cut biomass to produce a bagasse; (d) mechanically refining the bagasse at a first consistency and at a pH ranging from 6.5 to 7.5 without the addition of chemicals to yield a refined bagasse; (e) mechanically refining the refined bagasse at a pH ranging from 6.5 to 7.5 without the addition of chemicals at a second consistency, wherein the second consistency is less than the first consistency, to yield a high yield hesperaloe pulp useful in the manufacture of tissue products of the present invention. While in certain instances caustic or an oxidizing agent may be introduced to the process to facilitate fiber separation by the mechanical forces, such addition may not be necessary and in certain instances may be undesirable. For example, in certain instances it be desirable to produce hesperaloe pulp without the addition of caustic to improve yield and moderate the tensile strength of the resulting pulp. Without being bound by any particular theory, it is believed that omitting the addition of caustic during mechanic treatment, particularly mechanical treatment carried out a low consistency, such as consistencies of about 10% or less, particularly from about 3% to about 5%. Although, in certain instances, a caustic or oxidizing agent may be added during processing, it is generally preferred that the hesperaloe pulp fiber is not pretreated with a sodium sulfite or the like prior to processing. For example, high yield hesperaloe pulps are generally prepared without pretreatment of the fiber with an aqueous solution of sodium sulfite, or the like, which is commonly employed in the manufacture of chemi-mechanical wood pulps. In addition to hesperaloe pulp fibers, the tissue products may include one or more papermaking fibers such fibers derived from recycling of wastepaper, cellulosic fibers such as cotton linters, rayon, lyocell and bagasse non-wood pulp fibers and wood pulp fibers. Applicable wood pulps include chemical pulps, such as Kraft, sulfite, and sulfate pulps, as well as mechanical pulps including, for example, groundwood, thermomechanical pulp and chemically modified thermomechanical pulp. Chemical pulps, however, may be preferred. Pulps derived from both deciduous trees (hereinafter, also referred to as “hardwood”) and coniferous trees (hereinafter, also referred to as “softwood”) may be utilized. Tissue webs useful in preparing spirally wound tissue products according to the present disclosure can vary depending upon the particular application. In general, the webs can be made from any suitable type of fiber. For instance, the base sheet can be made from pulp fibers, other natural fibers, synthetic fibers, and the like. Suitable cellulosic fibers for use in connection with this disclosure include secondary (recycled) papermaking fibers and virgin papermaking fibers in all proportions. Such fibers include, without limitation, hardwood and softwood fibers as well as nonwoody fibers. Noncellulosic synthetic fibers can also be included as a portion of the furnish. It has been found that a high quality product having a unique balance of properties may be made using predominantly secondary fibers or all secondary fibers. Tissue webs made in accordance with the present disclosure can be made with a homogeneous fiber furnish or can be formed from a stratified fiber furnish producing layers within the single- or multi-ply tissue product. Homogeneous webs, also referred to herein as blended, may be prepared such that the various fiber furnishes are distributed throughout the web, as illustrated in Figs. 1 and 2. As shown in FIG.1, the web 30 may comprise a first outer surface 31 and second outer surface 33, one or more of the outer surfaces 31, 33 may be brought into contact with the user’s skin during use depending upon how the web 30 is converted into a finished product. The web 30 further comprises a blend of hesperaloe pulp fibers 40 and wood pulp fibers 42. The homogenous nature of the fiber furnish is such that the hesperaloe pulp fibers 40 form a portion of both the first outer surface 31 and second outer surface 33. The inventive tissue products may also comprise a stratified web, which may be formed using equipment known in the art, such as a multi-layered headbox. Different fiber furnishes can be used in each layer in order to create a layer with the desired characteristics, however, it may be desirable to distribute the hesperaloe pulp fibers in two or more layers, particularly the layers forming the outer surfaces of the web. For example, as illustrated in FIG.2 the tissue web 30 may comprises a first outer surface 31 and second outer surface 33 where the first outer surface 31 is formed by a first fibrous layer 32 and the second outer surface 33 is formed by a second fibrous layer 34. A middle layer 36 is disposed between the first and second layers 32, 34. Both the first and second fibrous layers 32, 34 contain hesperaloe pulp fibers 40 and wood pulp fibers 42. The middle layer 36 may also contain hesperaloe pulp fibers 40 and wood pulp fibers 42. When constructing a web from a stratified fiber furnish, the relative weight of each layer may vary. For example, in one instance, when constructing a web containing three layers, each layer can be from about 15 to about 40 percent of the total weight of the web, such as from about 25 to about 35 percent of the weight of the web. Hesperaloe pulp fibers 40 may comprise from about 5 wt% to about 50 wt% of the total weight of the web and may be disposed in the first and second outer layers or may be disposed in the each of the layers in an equal amount. Although in certain instances the papermaking fibers may be deposited in layers to provide a stratified web, the inventors have now discovered that layer is not necessary to produce tissue products having desirable properties. Accordingly, in certain instances, it may be preferable to deposit hesperaloe pulp fibers throughout the web. In those instances, where a stratified headbox is used to form the web, hesperaloe pulp fibers may be deposited in two or more, or all of, the layers. In other instances, the web may not be stratified and may simply consist of hesperaloe and wood pulp fibers, such as hardwood kraft pulp fibers, blended together. Thus, in certain instances the hesperaloe pulp fibers may be distributed throughout the web, including the outer surface of the web. Wet strength resins may be added to the furnish as desired to increase the wet strength of the final product. Presently, the most commonly used wet strength resins belong to the class of polymers termed polyamide-polyamine epichlorohydrin resins. There are many commercial suppliers of these types of resins including Hercules, Inc. (Kymene™), Henkel Corp. (Fibrabond™), Borden Chemical (Cascamide™), Georgia-Pacific Corp. and others. These polymers are characterized by having a polyamide backbone containing reactive crosslinking groups distributed along the backbone. Other useful wet strength agents are marketed by American Cyanamid under the Parez™ trade name. In certain instances, particularly when the single ply tissue products of the present invention are intended for use as bath tissue, it may be desirable to omit permanent wet strength agents such that the products are readily dispersible water and may be flushed. Thus, in certain instances the products of the present invention are substantially free from permanent wet strength agents, particularly polyamide-polyamine epichlorohydrin resins. Although, it may be desirable to produce the products without the use of permanent wet strength agents, the product may include a temporary wet strength agent, such as polyacrylamide resins. Particularly useful temporary wet strength agents may include those sold under the tradename Baystrength (commercially available from Kemira, Atlanta, GA), which is a glyoxalated cationic polyacrylamide. In particular embodiments, when constructing a web containing two or more layers, only the layer contacting the Yankee dryer may have a strength chemical or resin added to the furnish of that layer. The selective incorporation of strength additives, such as a temporary wet strength agent, into the Yankee contacting layer is particularly beneficial when employing registered creping techniques. In addition to temporary wet strength agents, the products may include other dry strength resins such as carboxymethyl celluloses (CMC), any type of starch, starch derivatives and gums. Commercial suppliers of such resins are the same as those that supply the permanent wet strength resins discussed above. Tissue products of the present disclosure can generally be formed by any of a variety of creped papermaking processes known in the art. Preferably the tissue web is formed by creped through-air drying and more preferably through registered creped through-air drying. When forming multi-ply tissue products, the separate plies can be made from the same process or from different processes as desired. For example, in one embodiment, tissue webs may be creped, through-air dried webs formed using processes known in the art. To form such webs, an endless traveling forming fabric, suitably supported and driven by guide rolls, receives the layered papermaking stock issuing from the headbox. A vacuum box is disposed beneath the forming fabric and is adapted to remove water from the fiber furnish to assist in forming a web. From the forming fabric, a formed web is transferred to a second fabric. The fabric is supported for movement around a continuous path by a plurality of guide rolls. A pick-up roll designed to facilitate transfer of web from fabric to fabric may be included to transfer the web. Preferably the formed web is dried by transfer to the surface of a rotatable heated dryer drum, such as a Yankee dryer. The web may be transferred to an impression fabric which is then used to transfer the web to the Yankee dryer, or preferably, transferred to the Yankee dryer directly from the throughdrying fabric. In an embodiment, the throughdrying fabric is used to transfer the web to the surface of the Yankee dryer such that registration of the web with the throughdrying fabric pattern is maintained, and hence, high caliper and bulk of the web are maintained. In accordance with the present disclosure, the creping composition of the present disclosure may be applied topically to the tissue web while the web is traveling on the fabric or may be applied to the surface of the Yankee dryer for transfer onto one side of the tissue web. In this manner, the creping composition is used to adhere the tissue web to the Yankee dryer. In this embodiment, as the web is carried through a portion of the rotational path of the Yankee dryer surface, heat is imparted to the web causing most of the moisture contained within the web to be evaporated. The web is then removed from the Yankee dryer by a creping blade. Creping the web as it is formed further reduces internal bonding within the web and increases softness. Applying the creping composition to the web during creping, on the other hand, may increase the strength of the web. In another embodiment, the formed web is transferred to the surface of the rotatable heated dryer drum, which may be a Yankee dryer by a press roll. The press roll may, in one embodiment, comprise a suction pressure roll. In order to adhere the web to the surface of the dryer drum, a creping adhesive may be applied to the surface of the dryer drum by a spraying device. The spraying device may emit a creping composition as previously described in the present disclosure. The web is adhered to the surface of the dryer drum and then creped from the drum using the creping blade. If desired, the dryer drum may be associated with a hood. The hood may be used to force air against or through the web. In other embodiments, once creped from the dryer drum, the web may be adhered to a second dryer drum. The second dryer drum may comprise, for instance, a heated drum surrounded by a hood. The drum may be heated from about 25 to about 200°C, such as from about 100 to about 150°C. In order to adhere the web to the second dryer drum, a second spray device may emit an adhesive onto the surface of the dryer drum. For example, the second spray device may emit a creping composition as described above. The creping composition not only assists in adhering the tissue web to the dryer drum, but also is transferred to the surface of the web as the web is creped from the dryer drum by the creping blade. Once creped from the second dryer drum, the web may, optionally, be fed around a cooling reel drum and cooled prior to being wound on a reel. In addition to applying the creping composition during formation of the fibrous web, the creping composition may also be used in post-forming processes. For example, in one aspect, the creping composition may be used during a print-creping process. Specifically, once topically applied to a fibrous web, the creping composition has been found well-suited to adhering the fibrous web to a creping surface, such as in a print-creping operation. For example, once a fibrous web is formed and dried, in one aspect, the creping composition may be applied to at least one side of the web and the at least one side of the web may then be creped. In general, the creping composition may be applied to only one side of the web and only one side of the web may be creped, the creping composition may be applied to both sides of the web and only one side of the web is creped, or the creping composition may be applied to each side of the web and each side of the web may be creped. Once creped, the tissue web may be pulled through a drying station. The drying station can include any form of a heating unit, such as an oven energized by infra-red heat, microwave energy, hot air or the like. A drying station may be necessary in some applications to dry the web and / or cure the creping composition, depending upon the creping composition selected. However, in other applications a drying station may not be needed. FIG.3 illustrates a process for preparing tissue webs according to the present disclosure. A papermaking headbox 2 injects or deposits a furnish of an aqueous suspension of papermaking fibers onto a forming fabric 4 thereby forming a wet tissue web 6. The forming process of the present disclosure may be any conventional forming process known in the papermaking industry. Such formation processes include, but are not limited to, Fourdriniers, roof formers such as suction breast roll formers, and gap formers such as twin wire formers and crescent formers. The wet tissue web 6 forms on the forming fabric 4 as the forming fabric 4 revolves about guide rolls. The forming fabric 4 serves to support and carry the newly-formed wet tissue web 6 downstream in the process as the wet tissue web 6 is partially dewatered to a consistency of about 10 percent based on the dry weight of the fibers. Additional dewatering of the wet tissue web 6 may be carried out by known paper making techniques, such as vacuum suction boxes, while the forming fabric 4 supports the wet tissue web 6. The wet tissue web 6 may be additionally dewatered to a consistency of at least about 20 percent, more specifically between about 20 to about 40 percent, and more specifically about 20 to about 30 percent. The forming fabric 4 can generally be made from any suitable porous material, such as metal wires or polymeric filaments. For instance, some suitable fabrics can include, but are not limited to, Albany 84M and 94M available from Albany International (Albany, NY) Asten 856, 866, 867, 892, 934, 939, 959, or 937; Asten Synweve Design 274, all of which are available from Asten Forming Fabrics, Inc. (Appleton, WI); and Voith 2164 available from Voith Fabrics (Appleton, WI). Forming fabrics comprising nonwoven base layers may also be useful, including those of Scapa Corporation made with extruded polyurethane foam such as the Spectra Series. The wet tissue web 6 is then transferred from the forming fabric 4 to a transfer fabric 8 while at a solids consistency of between about 10 to about 35 percent, and particularly, between about 20 to about 30 percent. As used herein, a “transfer fabric” is a fabric that is positioned between the forming section and the drying section of the web manufacturing process. Transfer to the transfer fabric 8 may be carried out with the assistance of positive and / or negative pressure. For example, in one embodiment, a vacuum shoe 10 can apply negative pressure such that the forming fabric 4 and the transfer fabric 8 simultaneously converge and diverge at the leading edge of the vacuum slot. Typically, the vacuum shoe 10 supplies pressure at levels between about 10 to about 25 inches of mercury. As stated above, the vacuum transfer shoe 10 (negative pressure) can be supplemented or replaced by the use of positive pressure from the opposite side of the web to blow the web onto the next fabric. In some embodiments, other vacuum shoes can also be used to assist in drawing the fibrous web 6 onto the surface of the transfer fabric 8. Typically, the transfer fabric 8 travels at a slower speed than the forming fabric 4 to enhance the MD and CD stretch of the web, which generally refers to the stretch of a web in its cross (CD) or machine direction (MD) (expressed as percent elongation at sample failure). For example, the relative speed difference between the two fabrics can be from about 1 to about 30 percent, in some embodiments from about 5 to about 20 percent, and in some embodiments, from about 10 to about 15 percent. This is commonly referred to as “rush transfer”. During “rush transfer”, many of the bonds of the web are believed to be broken, thereby forcing the sheet to bend and fold into the depressions on the surface of the transfer fabric 8. Such molding to the contours of the surface of the transfer fabric 8 may increase the MD and CD stretch of the web. Rush transfer from one fabric to another can follow the principles taught in any one of the following patents, US Patent Nos. 5,667,636, 5,830,321, 4,440,597, 4,551,199, 4,849,054, all of which are hereby incorporated by reference herein in a manner consistent with the present disclosure. The wet tissue web 6 is then transferred from the transfer fabric 8 to a throughdrying fabric 12. Typically, the transfer fabric 8 travels at approximately the same speed as the throughdrying fabric 12. However, it has now been discovered that a second rush transfer may be performed as the web is transferred from the transfer fabric 8 to a throughdrying fabric 12. This rush transfer is referred to herein as occurring at the second position and is achieved by operating the throughdrying fabric 12 at a slower speed than the transfer fabric 8. By performing rush transfer at two distinct locations, i.e., the first and the second positions, a tissue product having increased CD stretch may be produced. In addition to rush transferring the wet tissue web 6 from the transfer fabric 8 to the throughdrying fabric 12, the wet tissue web 6 may be macroscopically rearranged to conform to the surface of the throughdrying fabric 12 with the aid of a vacuum transfer roll or a vacuum transfer shoe like vacuum shoe 10. If desired, the throughdrying fabric 12 can be run at a speed slower than the speed of the transfer fabric 8 to further enhance MD stretch of the resulting absorbent tissue product. The transfer may be carried out with vacuum assistance to ensure conformation of the wet tissue web 6 to the topography of the throughdrying fabric 12. While supported by the throughdrying fabric 12, the wet tissue web 6 is dried to a final consistency of about 94 percent or greater by a throughdryer 14. After the web is through-air dried, the web is creped. In order to adhere the web 6 to the Yankee dryer 20, a creping adhesive applicator 18 applies a creping adhesive to the Yankee dryer 20. The dried tissue web 16 is held in registration with the pattern of the throughdrying fabric 12 as the dried tissue web 16 is transferred to the Yankee dryer 20. The dried tissue web 16 is then creped from the Yankee dryer 20 with a creping blade 22. The dried tissue web 16 then passes through a winding nip and is wound into a roll of tissue 24 onto reel 26 for subsequent converting, such as slitting cutting, folding, and packaging. The web is transferred to the throughdrying fabric for final drying preferably with the assistance of vacuum to ensure macroscopic rearrangement of the web to give the desired bulk and appearance. The use of separate transfer and throughdrying fabrics can offer various advantages since it allows the two fabrics to be designed specifically to address key product requirements independently. For example, the transfer fabrics are generally optimized to allow efficient conversion of high rush transfer levels to high MD stretch while throughdrying fabrics are designed to deliver bulk and CD stretch. It is therefore useful to employ a transfer fabric having moderate degrees of coarseness and surface topography and throughdrying fabrics having high degrees of coarseness and surface topography. The result is that a relatively smooth sheet leaves the transfer section and then is macroscopically rearranged (with vacuum assist) by the high topography throughdrying fabric to yield a high bulk, high CD stretch web. Because of its commercial availability and practicality, throughdrying is well known and is one commonly used means for noncompressively drying the web for purposes of this invention. Suitable throughdrying fabrics include, without limitation, fabrics with substantially continuous machine direction ridges whereby the ridges are made up of multiple warp strands grouped together, such as those disclosed in US Patent No.6,998,024. Other suitable throughdrying fabrics include those disclosed in US Patent No. 7,611,607, which is incorporated herein in a manner consistent with the present disclosure, particularly the fabrics denoted as Fred (t1207-77), Jetson (t1207-6) and Jack (t1207-12). In certain embodiments, the t-807-1 transfer fabric available from Voith Fabrics (Appleton, WI) can be used as a throughdrying fabric. While coarse, high-topography throughdrying fabrics can increase CD stretch and bulk, they may also result in low web adhesion when the web is transferred to the Yankee dryer. Accordingly, in certain embodiments, it may be necessary to modify traditional creping compositions to accommodate the decreased adhesion. Particularly useful creping compositions, for example, may omit common release agents, such as mineral oils, vegetable oils, non-oil polymers and surfactants, such as those sold under the tradename Rezosol™ (Ashland, Inc., Covington, KY). The omission of a release agent from the creping composition has been found to result in high web adhesion, and hence, the web may be aggressively creped and “peeled” from the Yankee dryer with high web tension. The web tension may be roughly twice that is normally used for creped throughdried tissue produced on the same tissue machine. For example, in certain embodiments, web tensions may range from approximately 0.05 to 0.17 pounds per lineal inch (pli). In addition to modifying the creping composition, for example, in certain embodiments, an inverted creping blade may be used; that is, the blade may be turned 180 degrees from the normal configuration. In the wound product, it is often advantageous to wind the product with the softest side facing the consumer, and hence the shearing process to increase the softness of this side is preferred. However, it is also possible to treat the air side of the web rather than the fabric side, and in these embodiments, it would be possible to increase the air side softness to a level higher than that of the fabric side. In other embodiments, the web can be wound such that the crepe ratio, that is, the speed of the Yankee dryer divided by the speed of the reel drum can range from about 1.0 to about 1.2. Additionally, high web tension can be maintained between the Yankee and the reel to prevent sheet wrinkling. The target or desired basis weight of the tissue sheet may also affect the necessary processing conditions. In particular embodiments, as the basis weight increased, higher levels of rush transfer and lower crepe ratios were incorporated to produce tissue sheets and rolls of the present disclosure. In yet other embodiments, as the basis weight decreased, lower levels of rush transfer and higher crepe ratios were utilized to produce tissue sheets and rolls of the present disclosure. The process of the present disclosure is well suited to forming multi-ply tissue products. The multi-ply tissue products can contain two plies, three plies, or a greater number of plies. In one particular embodiment, a two ply rolled tissue product is formed according to the present disclosure in which both plies are manufactured using the same papermaking process, such as, for example, creped through-air dried. However, in other embodiments, the plies may be formed by two different processes. Generally, prior to being wound in a roll, the first ply and the second ply are attached together. Any suitable manner for laminating the webs together may be used. For example, the process may include a crimping device that causes the plies to mechanically attach together through fiber entanglement. In an alternative embodiment, however, an adhesive may be used in order to attach the plies together. In embodiments of the present disclosure, the sheet bulk of the creped tissue sheets can be greater than about 8.00 cubic centimeters per gram (cc / g). More specifically for embodiments of single ply tissue sheets, the sheet bulk sheet bulk greater than about 8.0 cc / g, more preferably greater than about 9.0 cc / g and still more preferably greater than about 10.0 cc / g, such as from about 8.0 to about 12.0 cc / g. The geometric mean tensile (GMT) strength will vary depending upon the fiber furnish used to produce the tissue sheet, the manner in which the tissue web is produced and the basis weight of the tissue web. The GMT of creped tissue sheets formed according to the present disclosure may be about 700 g / 3” or greater, such as about 800 g / 3” or greater, such as about 900 g / 3” or greater, such as about 1,000 g / 3” or greater, such as from about 700 to about 1,500 g / 3”, such as from about 800 to about 1,300 g / 3”, such as from about 900 to about 1,200 g / 3”, such as about 700 g / 3”, such as about 800 g / 3”, such as about 900 g / 3”, such as about 1,000 g / 3”, such as about 1,100 g / 3”, such as about 1,200 g / 3”. While the creped tissue webs of the present disclosure generally have lower geometric mean slopes compared to webs of the prior art, the webs maintain a sufficient amount of tensile strength to remain useful to the consumer. For example, in certain instances, the disclosure provides single ply tissue webs having a GMT from about 700 to about 1,200 g / 3” and a GM Slope from about GM slope of about 10.0 kg or less, such as from about 4.0 to about 10.0 kg, such as from about 4.0 to about 8.0 kg, such as from about 4.0 to about 6.0 kg, such as about 4.0 kg, such as about 4.5 kg, such as about 5.0 kg, such as about 5.5 kg, such as about 6.0 kg. Additionally, improved Stiffness Index is of particular significance to the consumer because tissue products, such as those prepared according to the present disclosure, should have a moderate degree of flexibility while in use. The amount of flexibility of the tissue sheet contributes to the consumer’s perception of softness. If a tissue product has a high Stiffness Index value, the tissue sheet may not easily conform to the user’s hand, face or body; while a low Stiffness Index value indicates a more flexible tissue sheet. Single ply tissue sheet embodiments of the present disclosure preferably have a Stiffness Index of about 7.50 or less, such as less than about 7.00, such as less than about 6.50, such as less than about 6.00, such as from about 4.00 to about 7.50, such as from about 4.00 to about 6.00. The reduction in sheet stiffness and improvements in softness, generally do not come at the expense of durability, such as dry burst and tear strength. Accordingly, in certain instances, the tissue products of the present invention have a dry burst strength greater than about 500 gf, such as greater than about 525 gf, such as greater than about 550 gf, such as from about 500 gf to about 700 gf, such as from about 500 to about 600 gf. In other instances, the products have a GM Tear greater than about 8.0 gf, such as greater than about 8.5 gf, such as greater than about 9.0 gf, such as greater than about 9.5 gf, such as from about 8.0 to about 10.0 gf. Rolled tissue products made according to the present disclosure can exhibit the above creped tissue sheet properties at various basis weights. For example, single ply tissue sheet embodiments of the present disclosure can have a basis weight from about 30 gsm to about 80 gsm, such as from about 35 gsm to about 60 gsm, such as from about 35 to about 45 gsm, including exemplary values of about 35 gsm, about 38 gsm, about 40 gsm, about 42gsm, about 45 gsm. The basis weight of the single ply creped tissue sheets of the present disclosure is of significance because the spirally wound tissue products have a unique combination of properties that represent various improvements over prior art products. For instance, rolled tissue products prepared according to the present disclosure may have improved softness and bulk while still maintaining strength with the use of less material than prior art tissue webs. TEST METHODS Fiber Properties Fiber properties such as length, coarseness, percentage of fines, and fraction of very long fiber, are generally determined using an OpTest Fiber Quality Analyzer-360 (OpTest Equipment, Inc., Hawkesbury, ON) in accordance with the manufacturer's instructions. Samples are generally prepared by first accurately weighing a pulp sample. The sample mass may range from about 10 to about 50 mg (bone dry) and may be taken from a handsheet or pulp sheet. The weighed sample is diluted to a known consistency (between about 2 and about 10 mg / l). An aliquot of the diluted sample (usually 200 ml) is further diluted to a final volume of 600 ml and placed in the analyzer. The sample is then analyzed according to the manufacturer’s instructions and the output of the analyzer, such as the length weighted average fiber length, coarseness, length weighted fines, and a histogram illustrating the distribution of various fiber properties for a given sample are recorded. Generally, each reported fiber property is the average of three replicates. The output of the fiber quality analyzer is used to calculate the Very Long Fiber (VFL) fraction, which is the sum of fiber count from 6 to 14.95 mm divided by the total fiber count. Generally, the bin data output by the instrument, which provides the number of individual fibers counted within a given fiber length range, is used to determine VLF. The total number of individual fibers counted (N) and the total number of individual fibers counted having a length of 6 mm or greater (n) are determined from the bin data. The %VLF = n / N*100. The output of the fiber quality analyzer is also used to calculate the ratio of the length weighted average fiber length (Lw) to the number average fiber length (Ln). Lw and Ln are calculated by the FQA software using the following equations: =∑ '(( )$*+,- #$%$&=∑ '(( )$*+,- #$%$! ∑ ' # ∑' Where n and L are a sample. The ratio of the length weighted average fiber length (Lw) to the number average fiber length (Ln) indicates the fiber length distribution of the sample. A higher ratio is indicative of a broader fiber length distribution. A value of 1 indicates that all of the fibers in the sample have the same length. Fiber coarseness is measured using the FQA instrument and is measured “as-is” without removal of fines. Consistency of the pulp sample is determined using TAPPI methods T-240 or the equivalent and the consistency (%) is recorded to the nearest 0.01%. Based upon the measured consistency, the amount of undried sample required to yield approximately 0.015 grams of oven dried pulp is calculated and weighed out and the weight recorded to the nearest 0.0001 g. The weighed undried pulp is transferred to a British pulp disintegrator or equivalent pulp disintegrator and the total volume of the sample is diluted to 2 liters with deionized water and disintegrated 15,000 revolutions according to the manufacturer’s instructions. The disintegrated sample is further diluted with deionized water to a total volume of 5 liters ± 50 mL and the volume is recorded to the nearest 10 mL. The diluted sample is agitated by stirring and approximately 600 grams are weighted out into a clean beaker. The mass of the sample weighed out to the beaker is recorded to the nearest 0.1 g. The oven dried weight of the pulp sample to be analyzed is then calculated as shown in the equation below and fiber analysis is carried out according to the manufacturer’s instructions... ^. ^0^^ ^^ 12^^ ^^^ =3#4567489:; ^<^= >?#@6@A7#BC ?D 9#45674 @EF;:7 ^%^ = HE@@ ?D IEF;:7 ^<^ Basis weight of sample is measured by selecting twelve (12) products (also referred to as sheets) of the sample and making two (2) stacks of six (6) sheets. In the event the sample consists of perforated sheets of bath or towel tissue, the perforations must be aligned on the same side when stacking the usable units. A precision cutter is used to cut each stack into exactly 10.16 × 10.16 cm (4.0 × 4.0 inch) squares. The two stacks of cut squares are combined to make a basis weight pad of twelve (12) squares thick. The basis weight pad is then placed in the uncovered container and the container with sample is placed in a 105 ±2 °C oven for an hour. After an hour, the lid is placed on the container and the container is removed from the oven and allowed to cool to approximately room temperature. The covered container with sample is then weighed on a top loading balance with a minimum resolution of 0.01 grams. The top loading balance must be protected from air drafts and other disturbances using a draft shield. Weights are recorded when the readings on the top loading balance become constant. The weight of the container and lid are subtracted to determine the sample weight in grams. The mass of the sample (grams) per unit area (square meters) is calculated and reported as the basis weight, having units of grams per square meter (gsm). Caliper Caliper is measured in accordance with TAPPI test methods Test Method T 580 pm-12 “Thickness (caliper) of towel, tissue, napkin and facial products.” The micrometer used for carrying out caliper measurements is an Emveco 200-A Tissue Caliper Tester (Emveco, Inc., Newberg, OR). The micrometer has a load of 2 kilo-Pascals, a pressure foot area of 2,500 square millimeters, a pressure foot diameter of 56.42 millimeters, a dwell time of 3 seconds and a lowering rate of 0.8 millimeters per second. Burst Strength (Wet or Dry) Burst Strength is measured using an EJA Burst Tester (series #50360, commercially available from Thwing-Albert Instrument Company, Philadelphia, PA). The test procedure is according to TAPPI T570 pm-00 except the test speed. The test specimen is clamped between two concentric rings whose inner diameter defines the circular area under test. A penetration assembly, the top of which is a smooth, spherical steel ball, is arranged perpendicular to and centered under the rings holding the test specimen. The penetration assembly is raised at 6 inches per minute such that the steel ball contacts and eventually penetrates the test specimen to the point of specimen rupture. The maximum force applied by the penetration assembly at the instant of specimen rupture is reported as the burst strength in grams force (gf) of the specimen. The penetration assembly consists of a spherical penetration member which is a stainless- steel ball with a diameter of 0.625 ± 0.002 inches (15.88 ± 0.05 mm) finished spherical to 0.00004 inches (0.001 mm). The spherical penetration member is permanently affixed to the end of a 0.375 ± 0.010 inch (9.525 ± 0.254 mm) solid steel rod. A 2000 gram load cell is used and 50 percent of the load range i.e., 0-1000 g is selected. The distance of travel of the probe is such that the upper most surface of the spherical ball reaches a distance of 1.375 inches (34.9 mm) above the plane of the sample clamped in the test. A means to secure the test specimen for testing consisting of upper and lower concentric rings of approximately 0.25 inches (6.4 mm) thick aluminum between which the sample is firmly held by pneumatic clamps operated under a filtered air source at 60 psi. The clamping rings are 3.50 ± 0.01 inches (88.9 ± 0.3 mm) in internal diameter and approximately 6.5 inches (165 mm) in outside diameter. The clamping surfaces of the clamping rings are coated with a commercial grade of neoprene approximately 0.0625 inches (1.6 mm) thick having a Shore hardness of 70-85 (A scale). The neoprene needs not cover the entire surface of the clamping ring but is coincident with the inner diameter, thus having an inner diameter of 3.50 ± 0.01 inches (88.9 ± 0.3 mm) and is 0.5 inches (12.7 mm) wide, thus having an external diameter of 4.5 ± 0.01 inches (114 ± 0.3 mm). For each test a total of 3 sheets of product are combined. The sheets are stacked on top of one another in a manner such that the machine direction of the sheets is aligned. Where samples comprise multiple plies, the plies are not separated for testing. In each instance the test sample comprises 3 sheets of product. For example, if the product is a 2-ply tissue product, 3 sheets of product, totaling 6 plies are tested. If the product is a single ply tissue product, then 3 sheets of product totaling 3 plies are tested. Samples are conditioned under TAPPI conditions for a minimum of four hours and cut into 127 × 127 ± 5 mm squares. For wet burst measurement, after conditioning the samples were wetted for testing with 0.5 mL of deionized water dispensed with an automated pipette. The wet sample is tested immediately after insulting. The peak load (gf) and energy to peak (g-cm) are recorded and the process repeated for all remaining specimens. A minimum of five specimens are tested per sample and the peak load average of five tests is reported. Tear Tear testing was carried out in accordance with TAPPI test method T-414 “Internal Tearing Resistance of Paper (Elmendorf-type method)” using a falling pendulum instrument such as Lorentzen & Wettre Model SE 009. Tear strength is directional, and MD and CD tear are measured independently. More particularly, a rectangular test specimen of the sample to be tested is cut out of the tissue product or tissue base sheet such that the test specimen measures 63 ± 0.15 mm (2.5 ± 0.006 inches) in the direction to be tested (such as the MD or CD direction) and between 73 and 114 mm (2.9 and 4.6 inches) in the other direction. The specimen edges must be cut parallel and perpendicular to the testing direction (not skewed). Any suitable cutting device, capable of the prescribed precision and accuracy, can be used. The test specimen should be taken from areas of the sample that are free of folds, wrinkles, crimp lines, perforations or any other distortions that would make the test specimen abnormal from the rest of the material. The number of plies or sheets to test is determined based on the number of plies or sheets required for the test results to fall between 20 to 80 percent on the linear range scale of the tear tester and more preferably between 20 to 60 percent of the linear range scale of the tear tester. The sample preferably should be cut no closer than 6 mm (0.25 inch) from the edge of the material from which the specimens will be cut. When testing requires more than one sheet or ply the sheets are placed facing in the same direction. The test specimen is then placed between the clamps of the falling pendulum apparatus with the edge of the specimen aligned with the front edge of the clamp. The clamps are closed, and a 20-millimeter slit is cut into the leading edge of the specimen usually by a cutting knife attached to the instrument. For example, on the Lorentzen & Wettre Model SE 009 the slit is created by pushing down on the cutting knife lever until it reaches its stop. The slit should be clean with no tears or nicks as this slit will serve to start the tear during the subsequent test. The pendulum is released and the tear value, which is the force required to completely tear the test specimen, is recorded. The test is repeated a total of ten times for each sample and the average of the ten readings reported as the tear strength. Tear strength is reported in units of grams of force (gf). The average tear value is the tear strength for the direction (MD or CD) tested. The “geometric mean tear strength” is the square root of the product of the average MD tear strength and the average CD tear strength. The Lorentzen & Wettre Model SE 009 has a setting for the number of plies tested. Some testers may need to have the reported tear strength multiplied by a factor to give a per ply tear strength. For base sheets intended to be multiple ply products, the tear results are reported as the tear of the multiple ply product and not the single ply base sheet. This is done by multiplying the single ply base sheet tear value by the number of plies in the finished product. Similarly, the tear strength of products comprising multiple plies is reported as the tear strength for the finished product sheet and not the individual plies. A variety of means can be used to calculate but in general will be done by inputting the number of sheets to be tested rather than the number of plies to be tested into the measuring device. For example, two sheets would be two 1-ply sheets for 1-ply product and two 2-ply sheets (4-plies) for 2-ply products. Wet and Dry Tensile Samples for tensile strength testing are prepared by cutting a 3 inches (76.2 mm) by 5 inches (127 mm) long strip in either the machine direction (MD) or cross-machine direction (CD) orientation using a JDC Precision Sample Cutter (Thwing-Albert Instrument Company, Philadelphia, PA, Model No. JDC 3-10, Ser. No. 37333). The instrument used for measuring tensile strengths is an MTS Systems Sintech 11S, Serial No.6233. The data acquisition software is MTS TestWorksTMfor Windows Ver.4 (MTS Systems Corp., Research Triangle Park, NC). The load cell is selected from either a 50 Newton or 100 Newton maximum, depending on the strength of the sample being tested, such that the majority of peak load values fall between 10 and 90 percent of the load cell’s full scale value. The gauge length between jaws is 4 ± 0.04 inches. The jaws are operated using pneumatic-action and are rubber coated. The minimum grip face width is 3 inches (76.2 mm), and the approximate height of a jaw is 0.5 inches (12.7 mm). The crosshead speed is 10 ± 0.4 inches / min (254 ± 1 mm / min), and the break sensitivity is set at 65 percent. The sample is placed in the jaws of the instrument, centered both vertically and horizontally. The test is then started and ends when the specimen breaks. The peak load is recorded as either the “MD tensile strength” or the “CD tensile strength” of the specimen depending on the sample being tested. At least six (6) representative specimens are tested for each product, taken “as is,” and the arithmetic average of all individual specimen tests is either the MD or CD tensile strength for the product. Wet tensile strength was measured in the same manner as dry strength except that the samples were wetted prior to testing. Specifically, in order to wet the sample, a 3″×5″ tray was filled with distilled or deionized water at a temperature of approximately 23° C. The water is added to the tray to an approximate one-centimeter depth. A 3M “Scotch-Brite” general purpose scrubbing pad is then cut to dimensions of 2.5″×4″. A piece of masking tape approximately 5″ long is placed along one of the 4″ edges of the pad. The masking tape is used to hold the scrubbing pad. The scrubbing pad is then placed into the water with the taped end facing up. The pad remains in the water at all times until testing is completed. The sample to be tested is placed on blotter paper that conforms to TAPPI T205. The scrubbing pad is removed from the water bath and tapped lightly three times on a screen associated with the wetting pan. The scrubbing pad is then gently placed on the sample parallel to the width of the sample in the approximate center. The scrubbing pad is held in place for approximately one second. The sample is then immediately put into the tensile tester and tested. To calculate the wet / dry tensile strength ratio, the wet tensile strength value was divided by the dry tensile strength value. Absorbency As used herein, “vertical absorbent capacity” is a measure of the amount of water absorbed by a paper product (single-ply or multi-ply) or a sheet, expressed as grams of water absorbed per gram of fiber (dry weight). In particular, the vertical absorbent capacity is determined by cutting a sheet of the product to be tested (which may contain one or more plies) into a square measuring 100 millimeters by 100 millimeters (± 1 mm.) The resulting test specimen is weighed to the nearest 0.01 gram and the value is recorded as the “dry weight.” The specimen is attached to a 3-point clamping device and hung from one corner in a 3-point clamping device such that the opposite corner is lower than the rest of the specimen, then the sample and the clamp are placed into a dish of water and soaked in the water for 3 minutes (± 5 seconds). The water should be distilled or de-ionized water at a temperature of 23 ± 3°C. At the end of the soaking time, the specimen and the clamp are removed from the water. The clamping device should be such that the clamp area and pressure have minimal effect on the test result. Specifically, the clamp area should be only large enough to hold the sample and the pressure should also just be sufficient for holding the sample, while minimizing the amount of water removed from the sample during clamping. The sample specimen is allowed to drain for 3 minutes (± 5 seconds). At the end of the draining time, the specimen is removed by holding a weighing dish under the specimen and releasing it from the clamping device. The wet specimen is then weighed to the nearest 0.01 gram and the value recorded as the “wet weight”. The vertical absorbent capacity in grams per gram = [(wet weight - dry weight) / dry weight]. At least five (5) replicate measurements are made on representative samples from the same roll or box of product to yield an average vertical absorbent capacity value. Tissue Softness Analyzer Softness was measured using an EMTEC Tissue Softness Analyzer (“TSA”) (Emtec Electronic GmbH, Leipzig, Germany), calibrated according to the manufacturer’s instructions. The TSA comprises a rotor with vertical blades which rotate on the tissue sample applying a defined contact pressure. The blades are pressed against the sample with a load of 100 mN and the rotational speed of the blades is two revolutions per second. Contact between the vertical blades and the tissue sample creates vibrations, which are sensed by a vibration sensor. The sensor then transmits a signal to a PC for processing and display. The signal is displayed as a frequency spectrum. The frequency analysis in the range of approximately 200 to 1000 Hz represents the surface smoothness or texture of the sample. A high amplitude peak occurring between 200 to 1000 Hz correlates to a rougher surface and is reported as the TS750 value, having units of dB V2 rms. A further peak in the frequency range between 6 and 7 kHZ represents the softness of the sample. The peak in the frequency range between 6 and 7 kHZ is herein referred to as the TS7 value and is expressed as dB V2 rms. A high amplitude peak correlates to less soft surface, while a low amplitude peak correlates a softer surface. Tissue product samples were prepared by cutting a circular sample having a diameter of 112.8 mm. All samples were allowed to equilibrate at TAPPI conditions for at least 24 hours prior to completing the TSA testing. After conditioning each sample was tested as-is, i.e., multi-ply products were tested without separating the sample into individual plies. Samples are mounted into the instrument and the test is carried out according to the manufacturer's instructions. When complete, the TSA software displays values for TS7 and TS750. These values are recorded to the nearest 0.01 dB V2 rms. Once testing is complete, the sample is removed from the instrument and discarded. The test is performed on the top surface (outer facing surface of a rolled product) of five of the replicate samples, using a new sample for each test. The five test results are averaged and the average value is reported. EXAMPLES Base sheets were produced using a through-air dried tissue making process and creped after final drying (hereinafter referred to as “CTAD”). The targeted bone-dry basis weight of base sheets used to manufacture single ply tissue products was about 26 gsm and the base sheets used to manufacture single ply tissue products was about 38 gsm. In all cases the base sheets were produced from various fiber furnishes including Eucalyptus hardwood kraft (EHWK) pulp, Northern softwood kraft (NSWK) pulp, and high yield hesperaloe pulp (HYH) using a layered headbox fed by three stock chests. Blended structures were produced by blending the fibers prior to dispersing from the layered headbox. In all instances the fiber furnish consisted of 60 wt% EHWK and either 40 wt% NSWK or 40% HYH. The HYH was produced by mechanical pulping without the addition of chemicals and subsequently bleached. The fiber properties of the HYH pulp are summarized in Table 1, below. The specific furnish composition of each sample is described in more detail in Table 2, below. TABLE 1 Fiber Length (mm) 1.83 Very Long Fiber (%) 006 Sample Target EHWK NSWK HYH (wt%) Debonder Temporary Basis Wt (wt%) (wt%) (kg / MT) Wet Base sheet was prepared using a fibrous structure making machine having a layered headbox having a top chamber, a center chamber, and a bottom chamber. Each of the fiber furnishes were blended together immediately prior to pumping to the layered headbox and being dispersed onto a forming fabric. Dewatering occurs through the forming fabric and is assisted by a deflector and vacuum boxes. The embryonic wet web was transferred from the forming fabric at a fiber consistency of about 25% at the point of transfer, to transfer fabric and then from the transfer fabric to a patterned drying fabric. The drying fabric is designed to yield a pattern of substantially machine direction oriented linear channels. The drying fabric is formed by weaving warp and shute filaments to yield a textured sheet contacting surface having substantially continuous machine-direction ripples separated by valleys. The drying fabric was previously described in US Patent No.7,611,607 and was referred to therein as Fred (t1207-11). While the embryonic web is supported by the transfer fabric de-watering is accomplished by vacuum assisted drainage until the web has a fiber consistency of about 30%. The web is transferred from the transfer fabric to the drying fabric where it is pre-dried by air blow-through pre-dryers to a fiber consistency of about 65% by weight. After the pre-dryers, the semi-dry web is transferred to the Yankee dryer and adhered to the surface of the Yankee dryer with a sprayed creping adhesive comprising polyvinyl alcohol and Kymene™. The ratio of polyvinyl alcohol solids to Kymene™ solids was 24:1. The adhesive composition and add on rates were typical for standard creped throughdried tissue. The sheet was dried to a very high level (less than about 2 percent moisture) on the Yankee dryer to maximize bulk in the creping process. Yankee steam pressure was held at an average of approximately 25 to 35 psi for all samples. Two ply rolled tissue products were prepared from baseheeet samples 1, 2 and 3 by plying two plies of base sheet together (i.e., Rolled Product 1-1 continued two plies of baseheet sample1) using an embossing and glue lamination process followed by spirally winding the multiply, embossed and laminated web onto a core. Sing ply rolled tissue product was prepared from basesheet sample 4 by calendaring and spirally winding onto a core. Table 3, below, summarizes physical properties, of the rolled tissue products described above. Note that rolled product samples 1-3 comprised two plies of base sheet. Rolled product sample 4 comprised a single ply of base sheet.
