Definitions
- a method for making such tissues includes the use of a throughdrying fabric having high and long machine direction knuckles which impart a high degree of texture to the resulting tissue sheet.
- a throughdrying fabric having high and long machine direction knuckles which impart a high degree of texture to the resulting tissue sheet.
- the invention resides in a method of making a throughdried tissue sheet comprising (a) depositing an aqueous suspension of papermaking fibers onto a forming fabric to form a wet web; (b) dewatering the wet web to a consistency from about 20 to about 30 percent; (c) transferring the dewatered web from the forming fabric to the sheet side of a transfer fabric traveling at a speed from about 10 to about 80 percent slower than the forming fabric; (d) transferring the web to a throughdrying fabric having from about 5 to about 300 impression knuckles per square inch which are raised at least about 0.005 inch above the plane of the fabric, wherein the web is macroscopically rearranged to conform to the surface of the throughdrying fabric; and (e) throughdrying the web, wherein the sheet side of the transfer fabric contains cross-machine direction (CD) dominant troughs which impart cross-machine direction dominant bar-like protrusions to the air side of the tissue sheet.
- CD cross-machine direction
- the "dryer side” of the tissue sheet is the side of the sheet facing the throughdrying fabric during throughdrying and the "air side” of the sheet is the side of the sheet facing away from the throughdrying fabric during throughdrying.
- the air side of the sheet be the side of the sheet facing the core of the roll and the dryer side of the sheet be the outwardly facing side of the sheet.
- cross-machine direction dominant means that the bar-like protrusions or troughs run at an angle of about 44° or less, more specifically about 20° or less, and still more specifically about 10° or less, relative to the cross- machine direction of the sheet or fabric.
- the bar-like protrusions can be parallel with the cross-machine direction of the sheet.
- machine direction dominant means that the feature in question runs at an angle of about 44° or less, more specifically about 20° or less, and still more specifically about 10° or less, relative to the machine direction of the sheet or fabric.
- the machine direction dominant feature in question can also be parallel or substantially parallel to the machine direction of the sheet or fabric.
- the bar-like protrusions can extend continuously across the width of the sheet but, due to some slippage of the woven fabric filaments, in practice the bar-like protrusions within a given sheet randomly vary in length. Accordingly, the length of the bar-like protrusions can be about 3 millimeters or greater, more specifically from about 3 millimeters to about 300 millimeters, more specifically from about 5 millimeters to about 50 millimeters, and still more specifically from about 5 millimeters to about 25 millimeters, including combinations of the foregoing ranges.
- the width of the bar-like protrusions corresponds to the spacing between the CD dominant filaments of the transfer fabric and can be about 0.3 millimeter or greater, more specifically from about 0.3 to about 3 millimeters, still more specifically from about 0.5 to about 1.5 millimeters.
- single CD dominant filaments within the transfer fabric can be replaced with multiple CD dominant filaments piled atop each other to form deeper CD dominant troughs within the fabric and therefore form higher bar-like protrusions in the air side of the sheet.
- the invention resides in a tissue sheet having an air side and a dryer side, the dryer side of the sheet having parallel discontinuous rows of machine direction dominant pillow-like elevated regions, which can be imparted to the sheet by the spaces between high and long machine direction dominant knuckles in the throughdryer fabric, wherein the discontinuities in the rows of pillow-like elevated regions are cross- machine direction dominant troughs that appear as cross-machine direction dominant bar-like protrusions on the air side of the sheet.
- the discontinuities in the rows of pillowlike elevated regions substantially suppress the tendency of the rows of pillow-like elevated regions in the sheet from nesting when the sheet is wound into a roll.
- the invention resides in a method of making a throughdried tissue sheet comprising (a) depositing an aqueous suspension of papermaking fibers having a consistency of about 1 percent or less onto a forming fabric to form a wet web; (b) dewatering the wet web to a consistency from about 20 to about 30 percent; (c) transferring the dewatered web from the forming fabric to a transfer fabric traveling at a speed from about 10 to about 80 percent slower than the forming fabric; (d) transferring the web to a throughdrying fabric having from about 5 to about 300 impression knuckles per square inch which are raised at least about 0.005 inch above the plane of the fabric, wherein the web is macroscopically rearranged to conform to the surface of the throughdrying fabric; and (e) throughdrying the web, wherein the throughdrying fabric has an offset seam which results in the machine direction yarns of the throughdrying fabric being disposed at an angle of about 2° or less, more specifically about 1° or less, still more specifically
- offset means that the seam is formed after the edges of the fabric have been displaced in the cross-machine direction beyond that which may occur inadvertently during normal seaming operations.
- the concept of an offset seam will be more fully described in the description of Figure 11.
- the invention resides in a tissue sheet comprising generally parallel rows of elevated pillow-like regions running at an acute angle relative to the machine direction of the sheet.
- the angle can be from about 0.05° to about 2°, more specifically from about 0.05° to about 1°, and still more specifically from about 0.1° to about 0.6°.
- the angle results from an offset seam in the throughdrying fabric and substantially suppresses the tendency of the sheet to nest when wound into rolls.
- a similar result can be achieved with a conventionally seamed fabric, but by oscillating the roll upon which the web is being wound at an amplitude and frequency which suppresses the tendency of the features of the web to line up and nest and increases the roll bulk/roll firmness ratio relative to a roll of the same sheet material wound without oscillating the roll.
- the invention resides in a roll of tissue having a roll bulk of 16 cubic centimeters or greater per gram and a roll firmness of 8 millimeters or less. In another aspect, the invention resides in a roll of tissue having a roll bulk/roll firmness ratio of 20 or more square centimeters per gram and a sheet caliper from about 0.02 to about 0.05 inch.
- the invention resides in a roll of tissue having a roll bulk/roll firmness ratio of 20 or more square centimeters per gram and a geometric mean stiffness of about 8 or less.
- the invention resides in a roll of tissue having a roll bulk/roll firmness/single sheet caliper ratio of about 350 or more centimeters per gram and a geometric mean stiffness of about 8 or less.
- the roll bulk for rolls of tissue made in accordance with this invention can be 16 cubic centimeters or greater per gram of fiber, more specifically about 17 cubic centimeters or greater per gram of fiber, and still more specifically from about 17 to about 20 cubic centimeters per gram.
- the roll firmness of rolls of tissue made in accordance with this invention can be about 11 millimeters or less, more specifically about 8 millimeters or less, more specifically about 7 millimeters or less, more specifically about 6 millimeters or less, and still more specifically from about 4 to about 7 millimeters.
- the roll bulk/roll firmness ratio of rolls of tissue made in accordance with this invention can be 20 or more square centimeters per gram, more specifically about 25 or more square centimeters per gram, and still more specifically from about 25 to about 55 square centimeters per gram.
- the single sheet caliper of the tissue sheets useful for purposes of this invention can be from about 0.02 to about 0.05 inch (0.51 to about 1.27 millimeters), more specifically from about 0.025 to about 0.045 inch (0.64 to about 1.14 millimeters).
- the geometric mean stiffness of the tissue sheets useful for purposes of this invention can be about 8 or less, more specifically about 5 or less, and still more specifically from about 2 to about 5.
- the roll bulk/roll firmness/single sheet caliper ratio of rolls of tissue in accordance with this invention can be about 350 or more centimeters per gram, more specifically about 390 or more centimeters per gram, more specifically about 430 or more centimeters per gram, and still more specifically from about 350 to about 550 centimeters per gram.
- the absorbent capacity of the sheets useful for purposes of this invention can be about 5 or more grams of water per gram of fiber, more specifically from about 5 to about 8 grams of water per gram of fiber, and still more specifically from about 5.5 to about 7 grams of water per gram of fiber.
- the absorbent rate of sheets useful for purposes of this invention can be about 4 seconds or less, more specifically from about 1 to about 4 seconds, and still more specifically from about 2 to about 3 seconds.
- roll bulk is the bulk of the wound product, excluding the core volume, and is most easily understood with reference to Figure 2.
- Figure 2 illustrates a typical roll product having a core, around which the paper product is wound.
- the radius of the roll product is designated as "R”
- the radius of the core is designated as “r”
- the width or length of the roll is designated as "L”. All measurements are expressed as “centimeters”.
- the product roll weight "W” is the weight of the roll minus the weight of the core, measured in grams (g).
- the roll weight "W” can be calculated by multiplying the basis weight of the sheet, expressed in grams per square meter, by the area of the sheet (length times width), expressed in square meters. Either way, the "roll bulk", expressed in cubic centimeters per gram (cc/g), is "RV" divided by "W".
- roll firmness is a measure of the extent a probe can penetrate the roll under controlled conditions and is readily understood with reference to Figure 3, which illustrates the apparatus used for determining roll firmness.
- the apparatus is available from Kershaw Instrumentation, Inc., Swedesboro, NJ and is known as a Model RDT-101 Roll Density Tester. Shown in Figure 3 is a towel roll 80 being measured, which is supported on a spindle 81.
- a traverse table 82 begins to move toward the roll.
- a sensing probe 83 mounted to the traverse table. The motion of the traverse table causes the sensing probe to make contact with the towel roll.
- the sensing probe contacts the roll
- the force exerted on the load cell exceeds the low set point of 6 grams and the displacement display is zeroed and begins indicating the penetration of the probe.
- the traverse table stops and the displacement display indicates the penetration in millimeters.
- the tester records this reading.
- the tester rotates the towel roll 90° on the spindle and repeats the test.
- the roll firmness value is the average of the two readings, expressed in millimeters.
- the test is performed in a controlled environment of 73.4 + 1.8°F and 50 + 2% relative humidity. The rolls are conditioned in this environment at least 4 hours before testing.
- geometric mean stiffness is the geometric mean slope divided by the geometric mean tensile strength; where the geometric mean tensile strength is the square root of the product of the machine direction tensile strength and the cross- machine direction tensile strength, expressed in grams per 3 inches (7.62 cm); and where the geometric mean slope is the square root of the product of the machine direction slope and the cross machine direction slope, expressed in grams per 3 inches (7.62 cm); and where machine direction slope and cross machine direction slope are as described in U.S. 5,746,887 issued May 5, 1998 to Wendt et al. entitled Method of Making Soft Tissue Products, which is hereby incorporated by reference.
- the "single sheet caliper" is measured in accordance with TAPPI test method T402 "Standard Conditioning and Testing Atmosphere For Paper, Board, Pulp Handsheets and Related Products” and is measured as one sheet using an EMVECO 200-A Microgage automated micrometer (EMVECO, Inc., Oregon).
- the micrometer has an anvil diameter of 2.22 inches (56.4 millimeters) and an anvil pressure of 132 grams per square inch (per 6.45 square centimeters) (2.0 kPa).
- the "absorbent capacity" of tissue sheets is determined by cutting the tissue sheets into 4 inches by 4 inches squares, placing twenty squares into a stack such that all squares are oriented the same relative to the machine direction of the tissue, and stapling the corners of the stack together to form a 20 sheet pad.
- the pad is placed into a wire mesh basket with the staple points down and lowered into a water bath held at a temperature of 23°C ⁇ 2°C. When the pad is completely wetted, it is removed and allowed to drain for 30 seconds while in the wire basket. The weight of the water remaining in the pad after 30 seconds is the amount absorbed. This value is divided by the weight of the pad to determine the absorbent capacity, which for purposes herein is expressed as grams of water absorbed per gram of fiber.
- the "absorbent rate" of tissue sheets is determined by same procedure as for the absorbent capacity, except the size of the pad is 2.5 inches by 2.5 inches.
- the time taken for the pad to completely wet out after being lowered into the water bath is the absorbent rate, expressed in seconds. Higher numbers mean that the rate at which water is absorbed is slower.
- tissue sheets useful for purposes of this invention can have one, two, three or more plies and can be wet-pressed, throughdried, uncreped throughdried or wet molded and dried. They can be used for facial tissues, bath tissues, paper towels, dinner napkins and the like, although the greatest utility can be found in roll product forms such as bath tissue and paper towels.

- a twin wire former having a layered papermaking headbox 10 which injects or deposits a stream 11 of an aqueous suspension of papermaking fibers between forming fabrics 12 and 13.
- the web is adhered to forming fabric 13, which serves to support and carry the newly-formed wet web downstream in the process as the web is partially dewatered to a consistency of about 10 dry weight percent. Additional dewatering of the wet web can be carried out, such as by vacuum suction, while the wet web is supported by the forming fabric.
- the wet web is then transferred from the forming fabric to a transfer fabric 17 traveling at a slower speed than the forming fabric in order to impart increased MD stretch into the web.
- a kiss transfer is carried out to avoid compression of the wet web, preferably with the assistance of a vacuum shoe 18.
- the transfer fabric can be a fabric having high and long impression knuckles, generally as described in U.S. 5,672,248 to Wendt et al., previously mentioned, or it can have a smoother surface such as Asten 934, 937, 939, 959, Albany 94M or Appleton Mills 2164-B33.
- the transfer fabric can be as described in Figures 5, 6 and 7 of U.S. Patent No. 5,219,004 entitled "Multi-ply Papermaking Fabric With Binder Warps" issued June 15, 1993 to Chiu, which is hereby incorporated by reference. More particularly, referring to a transfer fabric as illustrated in Figure 6 of Chiu, the sheet side of the transfer fabric is the side of the fabric having the long cross-machine direction dominant floats created by filaments 144, and the cross-machine dominant bars in the sheet imparted by the transfer fabric correspond to the troughs formed between cross-machine direction dominant filaments 144.
- the web is then transferred from the transfer fabric to the throughdrying fabric 19 with the aid of a vacuum transfer roll 20 or a vacuum transfer shoe.
- the throughdrying fabric can be traveling at about the same speed or a different speed relative to the transfer fabric. If desired, the throughdrying fabric can be run at a slower speed to further enhance MD stretch. Transfer is preferably carried out with vacuum assistance to ensure deformation of the sheet to conform to the throughdrying fabric, thus yielding desired bulk, flexibility,' CD stretch and appearance.
- the throughdrying fabric is preferably of the high and long impression knuckle type generally described in Wendt et al.
- the level of vacuum used for the web transfers can be from about 3 to about 15 inches of mercury (75 to about 380 millimeters of mercury), preferably about 10 inches (254 millimeters) of mercury.
- the vacuum shoe (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 addition to or as a replacement for sucking it onto the next fabric with vacuum.
- a vacuum roll or rolls can be used to replace the vacuum shoe(s).
- the web While supported by the throughdrying fabric, the web is final dried to a consistency of about 94 percent or greater by the throughdryer 21 and thereafter transferred to a carrier fabric 22.
- the dried basesheet 23 is transported to the reel 24 using carrier fabric 22 and an optional carrier fabric 25.
- An optional pressurized turning roll 26 can be used to facilitate transfer of the web from carrier fabric 22 to fabric 25.
- Suitable carrier fabrics for this purpose are Albany International 84M or 94M and Asten 959 or 937, all of which are relatively smooth fabrics having a fine pattern.
- reel calendering or subsequent off-line calendering can be used to improve the smoothness and softness of the basesheet.
- Figures 2 and 3 have been previously described in connection with the roll bulk and roll firmness measurements.
- Figures 4, 5, 6 and 7 are plots comparing certain properties of commercially available products with the products of this invention made in accordance with the Examples described below.
- Figures 8A and 8B are photographs of the dryer side of an uncreped throughdried tissue sheet made in accordance with this invention (8A) and a similar sheet made without using the methods of this invention (8B). Referring to Figure 8A, shown are the parallel rows of elevated pillow-like regions 85 running in the machine direction which are interrupted by the cross-machine direction dominant troughs 86 in the tissue sheet of this invention. In Figure 8B, structure corresponding to the cross-machine dominant troughs is absent.

- Figure 10 is a photograph of the sheet side of an Appleton Mills 2054-A33 transfer fabric used to impart the cross-machine direction dominant bar-like protrusions to the air side of the sheet illustrated in Figures 8A and 9A in accordance with an aspect of this invention.
- Figures 11 A, 11B and 11C are schematic diagrams illustrating the steps used to make a fabric with an offset seam for purposes of this invention. Initially, as shown in Figure 11A, the fabric 100 is laid flat and the degree of offset is determined. Parallel offset lines 102 and 103 are drawn near the edges of the fabric as shown. The angle of these lines relative to the edge of the fabric represents the degree of offset relative to the machine direction of the fabric.
- the fabric is then formed into a continuous loop with the offset lines aligned as shown in Figure 11B.
- the two adjacent edges of the fabric are then seamed together.
- the excess fabric material is then trimmed away using a hot knife or other suitable means, leaving an offset fabric as illustrated in Figure 11C.
- the seam 104 of the resulting fabric is not perpendicular to the machine direction of the fabric.
- An uncreped throughdried tissue sheet was made in accordance with this invention as described above in connection with Figure 1. More specifically, a non- layered single ply towel tissue was made using a furnish comprising 50 dry weight percent northern softwood kraft fiber (NSWK), 25 % northern softwood bleached chemi- thermomechanical fiber (BCTMP), and 25 % southern hardwood kraft fiber (SHWK).
