Definitions
- Two well known processes include wet pressing, in which the newly formed wet web is partially dewatered by compressing the web between a papermaking felt and a pressure roll, and throughdrying, in which the web is at least partially dried by passing hot air through the web.
- the wet pressing process generally includes drying the wet pressed web on a Yankee dryer and creping.
- the throughdrying process may or may not be include creping the dried web.
- the fiber composition within the tissue web during its formation by using a layered headbox.
- a layered headbox By layering the fibers in the web, such as predominantly positioning the shorter hardwood fibers in the outer layer(s) and the longer softwood fibers in the center layer(s), certain advantages in tissue properties can be achieved.
- the short hardwood fibers such as eucalyptus fibers, are known to impart a softer feel to the tissue when placed in the outer layers, while the longer fibers provide the majority of the strength of the final tissue product.
- the MD/CD stretch ratio of tissue sheets can be lowered by transforming a layered web of long and short fibers in which long fibers are formed into a continuous frame-like network which provides a resilient strength having both tensile strength and stretch. Comparing the long fiber structure of the tissue sheets of this invention with the sheet structure of conventionally formed tissue sheets is similar to comparing a fish net material with a cloth material having similar material mass and strength. The fish net structure will have much higher resilient stretch while the cloth material may have slightly higher tensile strength.
- the invention resides in a layered tissue sheet containing long and short fibers, said sheet comprising at least one layer of predominantly long fibers arranged in a continuous frame-like network.
- a layer is preferably positioned such that it is not an outwardly facing layer in the finished tissue product.
- the relative amount of long fibers in the predominantly long fiber frame layer can be about 60 percent or greater, more specifically about 70 percent or greater, more specifically about 80 percent or greater, still more specifically about 90 percent or greater, and most specifically about 100 percent.
- the open area within the frame, or open cell area will have relatively fewer long fibers in relation to the amount of long fibers in the frame area.
- the relative amount of long fibers in the open cell area can be 60 percent or less, more specifically 50 percent or less, more specifically about 40 percent or less, and more specifically 30 percent or less.
- the short fibers within the sheet are also preferably layered, but in a substantially uniform manner, thereby overlaying the frame- like strength network of the long fiber layer.
- the relative amount of short fibers to the long fibers in the frame area can be about 50 percent or less, more specifically about 40 percent or less, and still more specifically about 30 percent or less.
- the amount of short fibers relative to the amount of long fibers in the open area can be about 50 percent or greater, more specifically about 60 percent or greater, more specifically 70 percent or greater, still more specially about 80 percent or greater.
- a specific open cell area can be about 1 mm or greater.
- the tissue sheets of this invention can have a total stretch (MD stretch + CD stretch) of about 20% or greater, more specifically 22% or greater, and an MD/CD stretch ratio of about 2 or less, more specifically 2.0 or less, more specifically from 1.0 to 2.0, and still more specifically from about 1.5 to about 1.9.
- the invention resides in a method of making a layered tissue sheet comprising: (a) depositing an aqueous suspension of papermaking fibers on a forming fabric to form a layered paper web; (b) rush transferring the layered web to a transfer fabric traveling at a speed which is less than the speed of the forming fabric; (c) transferring the layered web, while at a consistency of about 30 percent or less, to a throughdrying fabric having a web-contacting surface comprising a nonwoven membrane, preferably a bi-level or other multi-level membrane, said membrane having a pattern of high ridges and low ridges which surround openings through which water can be removed from the web; and (d) throughdrying the web.
- the web is throughdried to final dryness without any substantial compression of the web, thereby resulting in a tissue sheet having substantially uniform density.
- a relatively wet web (about 30 percent consistency or less) is transferred to a multilevel membrane through which additional water is removed from the web, either by throughdrying or non-compressive dewatering such as high vacuum suction.
- Each of the multiple levels is a plane defined by the tops of ridges which have the same height above the base of the membrane. Because the web is relatively wet, the fibers within the web are still relatively mobile. Consequently, when the web is transferred to the multi-level membrane having a pattern of high and low ridges, the long and short fibers rearrange themselves differently when contacting the tops of the various ridges.
- the long fibers tend to become draped over the tops of the ridges
- the short fibers pass through and become retained at the base of the membrane, such as by contact with a supporting woven fabric.
- the resulting sheet structure due to the multiple levels created by the different ridge heights and the reorientation of the long fibers, exhibits unique properties in the areas of stretch, strength and limpness.
- the particular multilevel ridge pattern presented by the multi-level membrane can vary greatly. When viewed from the top (plan view), a regular pattern of holes is presented, through which the water in the web is removed.
- the shape of the holes can round, triangular, square, pentagonal, hexagonal, heptagonal, hexagonal, etc. or irregular.
- FIG. 1 is a schematic process diagram illustrating a throughdrying method for making tissue sheets in accordance with this invention.
- Figure 2 is a schematic view of the transfer of the web to the throughdryer in the method illustrated in Figure 1.
- Figure 3 is a schematic illustration of the throughdrying fabric, illustrating a representative portion of the nonwoven membrane supported by the woven fabric.
- Figure 4 is a schematic view of the relatively selective or non-random deposition of long fibers in the presence of a nonwoven membrane in accordance with this invention.

- Figure 17 is a bar chart similar to that of Figure 14, but illustrating the effect on the geometric mean (GM) tensile strength slopes.
- GM geometric mean
- These fibers generally include hardwood fibers or fibers form deciduous trees or grasses.
- Basis weight is the weight of a tissue sheet per unit area, expressed as grams per square meter.
- Caliper is the thickness of a single tissue sheet measured under a minimal load, expressed in inches. Caliper is measured under laboratory conditions of 23.0 +/- 1.0 degrees Celcius and 50.0 +/- 2.0 percent relative humidity and only after the sheet has equilibrated to the testing conditions for a period of not less than four hours.
- the micrometer used for carrying out this measurement is an Emveco model 200-A with flat ground, circular pressure foot and anvil and with factory modifications to meet the following specifications: a round pressure foot diameter of 56.42 millimeters (equating to an area of 2500 square millimeters; pressure foot loading of 2.00 kiloPascals; 0 to 7.6 mm test capacity; readout resolution of 0.001 millimeters; repeatability of 0.001 millimeters; linearity of +/- 0.25 percent; dwell time of 3.0 +/- 1.0 seconds; lowering rate of 0.8 millimeters +/- 0.1 per second; and pressure foot and anvil to be parallel within 0.001mm.
- Dry burst strength is a measure of the tear resistance of a tissue sheet when subjected to a point source of applied force.
- the tissue sample is clamped and suspended horizontally. A foot descends onto the tissue until the tissue tears.
- the instrument records the peak load required to burst the tissue. More specifically, the dry burst strength is determined by using a Material Test Instrument (MTI) which consists of a foot (model 12), forming cup (model 41 , steel ring (model 31 ), and a 50 gram calibration weight.
- MMI Material Test Instrument
- the test sample is prepared as a single sheet with a size of 5" x 5" (127 x 127 mm) and is maintained at standard conditions (23°C and 50 percent relative humidity) for at least 4 hours. The test is run at the same conditions.
- MD tensile strength is the machine direction tensile strength of a 3-inches wide sample, expressed in grams. MD tensile strength is measured under laboratory conditions of 23.0 +/- 1.0 degrees Celcius and 50.0 +/- 2.0 percent relative humidity and only after the sheet has equilibrated to the testing conditions for a period of not less than four hours. Testing is done on a constant rate of elongation tensile testing machine. Specimen width is 3 inches. Jaw span (the distance between the jaws, sometimes referred to as gauge length) is 2.0 inches (50.8 mm.) Crosshead speed is 10 inches per minute (254 mm/min.) A load cell / full scale load is chosen so that the majority of peak load results fall between 20 and 80 percent of the full scale load.
- results described here were produced on an Instron 1 122 tensile frame connected to a Sintech data acquisition and control system utilizing I MAP software running on a '486 Class' personal computer. This data system records at least 20 load and elongation points per second.
- CD tensile strength is the cross-machine direction tensile strength of a 3-inches wide sample, expressed in grams, determined as described above for the MD tensile strength.
- GMT Garnier mean tensile strength
- MD stretch is the percent elongation in the machine direction at the point of failure when determining the MD tensile strength.
- CD stretch is the percent elongation in the cross-machine direction at the point of failure when determining the CD tensile strength.
- MD Slope is the two parameter least squares line regression coefficient (sometimes referred to as slope) obtained from the tensile load/elongation curve for all points falling between a load of 70 grams and 157 grams during the ascending part of the curve. The regression coefficient is multiplied by the jaw span and divided by the specimen width to normalize the result, resulting in the final MD Slope value.
- the MD Slope values may be obtained from the MD tensile curves utilized for the GMT calculation; MD Slope utilizes an identical 3 inch specimen width and two inch jaw span.
- the units for MD Slope are kilograms per 3 inches (7.62 centimeters), but for convenience, the MD Slope values are hereinafter referred to without units.
- CD Slope is determined as described above for the MD Slope.
- GM Slope is a mathematical calculation using the MD slope and the CD slope to express the overall sheet stiffness. It is determined by calculating the square root of ((MD slope) x (CD slope)).
- Figure 1 illustrates a method of making a tissue sheet in accordance with this invention. Shown is a tissue machine for making an uncreped throughdried tissue product. The manufacture of uncreped throughdried tissues is described in U.S. Patent No. 5,672,248 entitled “Method of Making Soft Tissue Products” issued September 30, 1997 to Wendt et al., which is hereby incorporated by reference.
- the tissue machine generally includes a layered headbox 1 , a forming fabric 2, a transfer fabric 3, a throughdrying (TAD) fabric 4, a throughdrying honey comb roll 5, a forced hot air hood 6, and a reel drum 7
- the newly formed web 8 can be formed in two or more layers
- a two layered web can have one layer of eucalyptus fibers (short fibers) and one layer of northern softwood kraft fibers (long fibers)
- the newly formed web is transferred from the forming fabric to the transfer fabric with assistance from a suitable vacuum box or transfer shoe 9
- the transfer fabric can be any suitable fabric that provides adequate support of the wet web Suitable transfer fabrics are disclosed in U S Patent No 5,667,636 entitled "Method For Making Smooth Uncreped Throughdried Sheets" issued September 16, 1997 to Engel et al, which is hereby incorporated by reference
- the transfer can be a rush transfer in which the forming fabric is traveling at a faster speed than the transfer fab
- the geometry of the high and low ridges can vary widely depending upon the desired properties of the resulting tissue sheet.
- the width 24 of the high ridges can be from about 2.0 mm to about 4.0 mm.
- the height 25 of the high ridges can be from about 1 mm to about 2 mm.
- the distance between the high ridges (which corresponds to the length of the low ridges) can be from about 1 mm to about 4mm.
- the width 26 of the low ridges can be from about 1 mm to about 4mm.
- the height 27 of the low ridges is less than the height of the high ridges and can be from about 0.5 to about 2 mm.
- the distance between the low ridges can be from about 0.5 to about 2mm.
- the ratio of the distances between the high ridges and the low ridges and their related width and heights will determine the long fiber mass distribution as illustrated below.
- the multilevel membrane can be attached to the support fabric with the high ridges oriented in the machine direction, or in the cross-machine direction, or at about 45° to the machine direction, or any other angle to the machine direction. Any means for attachment can be used depending upon the durability requirements of the fabric. Sewing the membrane to the support fabric works well.
- Figure 4 shows the sketch of long fibers 31 being deposited on a bilevel membrane, illustrating how the long fibers tend to drape over the top surfaces of the high ridges and the low ridges.
- the moisture content of the web prior to being transferred to the bilevel membrane must be high enough to allow fiber movement.
- the bilevel membrane acts as a screen for the long fibers which preferentially become trapped along the tops of the high ridges and the low ridges before reaching the support fabric. The result is a substantially higher concentration of long fibers along the tops of the membrane pattern.
- Figure 5 is a sketch similar to Figure 4, but further showing the random deposition of the short fibers on the membrane (and the supporting fabric).
- Figure 6 is a schematic representation of the long fiber mass distribution in a tissue sheet made in accordance with this invention. As shown, the long fibers 31 have been preferentially distributed along the membrane ridges to create a frame-like structure having relatively open areas 35.
- Figure 7 is similar to Figure 6, but further illustrates the random deposition of the short fibers 32 within the resulting sheet.
- Figures 8 and 9 are similar to Figures 6 and 7, respectively, but showing for comparison the formation of long and short fibers in a conventional tissue sheet. As shown, the conventional tissue sheet does not have the frame-like long fiber structure.
- Figure 10 is a photograph of a tissue sheet in accordance with this invention. The photograph was taken using transmitted, dark field light with a magnification of 5.8X. The frame-like structure within the sheet imparted by the long fibers is clearly evident.
- Figure 1 1 is a photograph similar to that of Figure 10, but taken at a magnification of 16X, further showing the frame-like structure.
- Figures 12 and 13 are photographs similar to Figures 10 and 11 , respectively, but for a conventionally formed tissue sheet. As shown, the deposition of both the long and short fibers is substantially random and lacks the frame-like structure illustrated in Figures 10 and 11.
- Figures 14-17 are bar charts setting forth selected physical properties for the tissues made in Examples 1-3 below. The first two bars represent control samples, while the third (dark) bar represents tissue sheets made in accordance with this invention. As shown, tissue sheets of this invention have increased CD stretch, a lower MD/CD stretch ratio, higher dry burst strength, and a lower GM slope. All of these changes are desirable for soft tissue products.
- Example 1 (Control 1 ).
- a throughdried tissue sheet was made generally as described in connection with Figure 1 , but without using a multi-level nonwoven membrane/fabric useful for creating the frame-like long fiber formation pattern in accordance with this invention. More specifically, a two-layered tissue web was formed on a forming wire using a two-layered headbox. The layer basis weight split was 50/50. The layer in contact with the forming fabric (and ultimately also contacting the throughdrying fabric) was 100 percent long fibers (northern softwood kraft). The opposite layer (the air side layer) was 100 percent short fibers (eucalyptus). The newly-formed web was transferred to a conventional transfer fabric at a consistency of about 18-22 percent with a rush transfer speed difference of 20-25 percent.
- the web was transferred to an Appleton Mills 1205 woven throughdrying fabric with the aid of a vacuum box.
- the vacuum level was about 10-20 inches of water.
- the sheet was throughdried to a consistency of 98 percent and wound up into a parent roll. Samples from the parent roll were collected and conditioned under standard TAPPI conditions for 24 hours. The conditioned samples were then submitted for physical property testing.
- Example 2 (Control 2).
- a tissue sheet was made as described in Example 1 , except the woven throughdrying fabric was an Aston 44GST fabric, which has a finer mesh than the fabric of Example 1.
- the process parameters and their ranges were equivalent to those of Example 1.
- the physical properties of the resulting tissue sheet are set forth in the table below, along with the data from Example 1.
- Example 3 (Invention). A tissue sheet was made as described in Example 1 , except that the throughdrying fabric consisted of a polyurethane bilevel nonwoven membrane sewn on top of an Aston 44GST fabric(4) as shown in Figure 3, such that the membrane contacted the
- tissue of this example exhibited the unique frame-like long fiber mass distribution as shown in Figures 10 and 11.
- the physical properties are set forth in the table below, which also includes the data from Examples 1 and 2 for ease of comparison.
- the unique long fiber mass distribution has generated a higher 1 sheet caliper of 0.0276 inch at similar fiber basis weight.
- the CD stretch values for the tissue sheets of this invention are a significantly higher than those made with conventional woven fabrics.
- a CD stretch comparison for the three examples is shown in Figure 14.
- the MD/CD stretch ratio for the tissue sheets of this invention were reduced to 1.86% from about 5.7% for conventional woven fabrics as shown in Figure 15.
- FIG. 16 illustrates the improvement in dry burst strength.
- a fish net long fiber distribution (35) provides lower slope as shown in above table.
- the tissue produced in accordance with this invention showed a drastic reduction in the geometric mean slope as illustrated in Figure 17.
- a fibrous tissue with lower geometric mean slope generally correlates with a more limp, softer feel.
