- 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 may be carried out with the assistance of positive and/or negative pressure.
- a vacuum shoe can apply negative pressure such that the forming fabric and the transfer fabric simultaneously converge and diverge at the leading edge of the vacuum slot.
- the vacuum shoe supplies pressure at levels between about 10 to about 25 inches of mercury.
- the vacuum transfer 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.
- other vacuum shoes can also be used to assist in drawing the fibrous web onto the surface of the transfer fabric.
- the transfer fabric travels at a slower speed than the forming fabric 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).
- the relative speed difference between the two fabrics can be from about 30 to about 70 percent and more preferably from about 40 to about 60 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. Such molding to the contours of the surface of the transfer fabric 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 is then transferred from the transfer fabric to a through-air drying fabric.
- the transfer fabric travels at approximately the same speed as the through-air drying fabric.
- a second rush transfer may be performed as the web is transferred from the transfer fabric to the through-air drying fabric. This rush transfer is referred to as occurring at the second position and is achieved by operating the through-air drying fabric at a slower speed than the transfer fabric.
- the wet tissue web may be macroscopically rearranged to conform to the surface of the through-air drying fabric with the aid of a vacuum transfer roll or a vacuum transfer shoe.
- the through-air drying fabric can be run at a speed slower than the speed of the transfer fabric 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 to the topography of the through-air drying fabric.
- the wet tissue web While supported by a through-air drying fabric, the wet tissue web is dried to a final consistency of about 94 percent or greater by a through-air dryer. The web then passes through the winding nip between the reel drum and the reel and is wound into a roll of tissue for subsequent converting.
- 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 TestWorksTM for 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.
- sample wetting is performed by first laying a single test strip onto a piece of blotter paper (Fiber Mark, Reliance Basis 120). A pad is then used to wet the sample strip prior to testing.
- the pad is a green, Scotch-Brite brand (3M) general purpose commercial scrubbing pad. To prepare the pad for testing, a full-size pad is cut approximately 2.5 inches long by 4 inches wide. A piece of masking tape is wrapped around one of the 4-inch long edges. The taped side then becomes the "top" edge of the wetting pad.
- the tester holds the top edge of the pad and dips the bottom edge in approximately 0.25 inches of distilled water located in a wetting pan. After the end of the pad has been saturated with water, the pad is then taken from the wetting pan and the excess water is removed from the pad by lightly tapping the wet edge three times across a wire mesh screen. The wet edge of the pad is then gently placed across the sample, parallel to the width of the sample, in the approximate center of the sample strip. The pad is held in place for approximately one second and then removed and placed back into the wetting pan. The wet sample is then immediately inserted into the tensile grips so the wetted area is approximately centered between the upper and lower grips.
- the test strip should be centered both horizontally and vertically between the grips. (It should be noted that if any of the wetted portion comes into contact with the grip faces, the specimen must be discarded and the jaws dried off before resuming testing.)
- the tensile test is then performed and the peak load recorded as the CD wet tensile strength of this specimen.
- the characterization of a product is determined by the average of at least six, but in the case of the examples disclosed, twenty representative sample measurements.
- 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).
- 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.
- 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).
- 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".
- Base sheets were made using a through-air dried papermaking process commonly referred to as “uncreped through-air dried” ("UCTAD”) and generally described in US Patent No. 5,607,551 , the contents of which are incorporated herein in a manner consistent with the present invention.
- Inventive base sheets were produced from a furnish comprising northern softwood kraft, eucalyptus kraft and fibrillated acrylic fibers using a layered headbox fed by three stock chests such that the webs having three layers (two outer layers and a middle layer) were formed.
- the outer layers comprised 100 percent eucalyptus kraft fiber for both the control and inventive samples.
- the center layer was 100 percent northern softwood kraft fiber for the control sample; for the inventive sample, the center layer was a 50/50 blend of northern softwood kraft and fibrillated acrylic fibers.
- the layer splits, by weight of the web, are detailed in Table 4, below.
- Fibrillated acrylic fibers were CFF® 106-3 (commercially available from Sterlingfibers Shelton, CT).
- the tissue web was formed on a Voith Fabrics TissueForm V forming fabric, vacuum dewatered to approximately 25 percent consistency and then subjected to rush transfer when transferred to the transfer fabric.
- the layer splits, by weight of the web, are detailed in Table 4, below.
- the transfer fabric was the fabric described as t1207-11 (commercially available from Voith Fabrics, Appleton, Wl).
- the web was then transferred to a through-air drying fabric. Transfer to the through-drying fabric was done using vacuum levels of greater than 10 inches of mercury at the transfer. The web was then dried to approximately 98 percent solids before winding.
- the base sheet webs were converted into rolled towel products by calendering using a conventional polyurethane/steel calender comprising a 4 P&J polyurethane roll on the air side of the sheet and a standard steel roll on the fabric side.
