- Value of a Common Intensive Property means a measured value of an intensive property that is present in two or more articles of manufacture.
- Basis Weight as used herein is the weight per unit area of a sample reported in lbs/3000 ft 2 or g/m 2 .
- Basis weight is measured by preparing one or more samples of a certain area (m ) and weighing the sample(s) of a fibrous structure according to the present invention and/or a sanitary tissue product comprising such fibrous structure on a top loading balance with a minimum resolution of 0.01 g. The balance is protected from air drafts and other disturbances using a draft shield. Weights are recorded when the readings on the balance become constant. The average weight (g) is calculated and the average area of the samples (m 2 ).
- the basis weight (g/m 2 ) is calculated by dividing the average weight (g) by the average area of the samples (m 2 ).
- the fibrous structures and/or sanitary tissue products according to the present invention exhibit a basis weight of from about 10 g/m 2 to about 120 g/m 2 and/or from about 20 g/m 2 to about 60 g/m 2 .
- Machine Direction or “MD” as used herein means the direction parallel to the flow of the fibrous structure through the papermaking machine and/or product manufacturing equipment.
- Cross Machine Direction or “CD” as used herein means the direction perpendicular to the machine direction in the same plane of the fibrous structure and/or sanitary tissue product comprising the fibrous structure.
- “Dry Tensile Strength” (or simply “Tensile Strength” as used herein) of a fibrous structure and/or sanitary tissue product is measured as follows. One (1) inch by five (5) inch (2.5 cm X 12.7 cm) strips of fibrous structure and/or sanitary tissue product are provided. The strip is placed on an electronic tensile tester Model 1122 commercially available from Instron Corp., Canton, Massachusetts in a conditioned room at a temperature of 73 °F + 4°F (about 28°C ⁇ 2.2 0 C) and a relative humidity of 50% + 10%. The crosshead speed of the tensile tester is 2.0 inches per minute (about 5.1 cm/minute) and the gauge length is 4.0 inches (about 10.2 cm). The Dry Tensile Strength can be measured in any direction by this method. The “Total Dry Tensile Strength" or “TDT” is the special case determined by the arithmetic total of MD and CD tensile strengths of the strips.
- the fibrous structures and/or sanitary tissue products according to the present invention exhibits an HFS absorbency of greater than about 5 g/g and/or greater than about 8 g/g and/or greater than about 10 g/g up to about 100 g/g. In another nonlimiting embodiment, the fibrous structures and/or sanitary tissue products according to the present invention exhibit an HFS absorbency of from about 12 g/g to about 20 g/g.
- “Lint” as used herein means any material that originated from a finished fibrous structure and/or sanitary tissue product comprising such finished fibrous structure that remains on a surface after which the finished fibrous structure and/or sanitary tissue product comprising such finished fibrous structure has come into contact.
- the lint value of a finished fibrous structure and/or sanitary tissue product comprising such finished fibrous structure is determined according to the Lint Test Method described herein.
- “Texture” as used herein means any pattern present in the fibrous structure. For example, a pattern may be imparted to the fibrous structure during the papermaking process, such as during a through-air-drying step. A pattern may also be imparted to the fibrous structure by embossing the finished fibrous structure during the converting process.
- Softness of a fibrous structure according to the present invention and/or a paper product comprising such fibrous structure is determined as follows. Ideally, prior to softness testing, the samples to be tested should be conditioned according to Tappi Method #T4020M-88. Here, samples are preconditioned for 24 hours at a relative humidity level of 10 to 35% and within a temperature range of 22°C to 4O 0 C. After this preconditioning step, samples should be conditioned for 24 hours at a relative humidity of 48% to 52% and within a temperature range of 22°C to 24°C. Ideally, the softness panel testing should take place within the confines of a constant temperature and humidity room. If this is not feasible, all samples, including the controls, should experience identical environmental exposure conditions.
- Softness testing is performed as a paired comparison in a form similar to that described in "Manual on Sensory Testing Methods", ASTM Special Technical Publication 434, published by the American Society For Testing and Materials 1968 and is incorporated herein by reference. Softness is evaluated by subjective testing using what is referred to as a Paired Difference Test. The method employs a standard external to the test material itself. For tactile perceived softness two samples are presented such that the subject cannot see the samples, and the subject is required to choose one of them on the basis of tactile softness. The result of the test is reported in what is referred to as Panel Score Unit (PSU). With respect to softness testing to obtain the softness data reported herein in PSU, a number of softness panel tests are performed.
- PSU Panel Score Unit
- each test ten practiced softness judges are asked to rate the relative softness of three sets of paired samples.
- the pairs of samples are judged one pair at a time by each judge: one sample of each pair being designated X and the other Y.
- each X sample is graded against its paired Y sample as follows:
- a grade of plus one is given if X is judged to may be a little softer than Y, and a grade of minus one is given if Y is judged to may be a little softer than X;
- a grade of plus two is given if X is judged to surely be a little softer than Y, and a grade of minus two is given if Y is judged to surely be a little softer than X;
- a grade of plus four is given to X if it is judged to be a whole lot softer than Y, and a grade of minus 4 is given if Y is judged to be a whole lot softer than X.
- the grades are averaged and the resultant value is in units of PSU.
- the resulting data are considered the results of one panel test. If more than one sample pair is evaluated then all sample pairs are rank ordered according to their grades by paired statistical analysis. Then, the rank is shifted up or down in value as required to give a zero PSU value to which ever sample is chosen to be the zero-base standard. The other samples then have plus or minus values as determined by their relative grades with respect to the zero base standard.
- the number of panel tests performed and averaged is such that about 0.2 PSU represents a significant difference in subjectively perceived softness.

- the amount of lint generated from a finished fibrous structure is determined with a Sutherland Rub Tester. This tester uses a motor to rub a weighted felt 5 times over the finished fibrous structure, while the finished fibrous structure is restrained in a stationary position. This finished fibrous structure can be is referred to throughout this method as the "web”.
- the Hunter Color L value is measured before and after the rub test. The difference between these two Hunter Color L values is then used to calculate a lint value.
- This lint method is designed to be used with white or substantially white fibrous structures and/or sanitary tissue products.
- the samples to be tested Prior to the lint rub testing, the samples to be tested should be conditioned according to Tappi Method #T402OM-88. Here, samples are preconditioned for 24 hours at a relative humidity level of 10 to 35% and within a temperature range of 22 0 C to 4O 0 C. After this preconditioning step, samples should be conditioned for 24 hours at a relative humidity of 48 to 52% and within a temperature range of 22°C to 24°C. This rub testing should also take place within the confines of the constant temperature and humidity room.
- the Sutherland Rub Tester may be obtained from Testing Machines, Inc. (Amityville, N. Y., 1701). The web is first prepared by removing and discarding any product which might have been abraded in handling, e.g.
- this test can be used to make a lint measurement on the multi-ply product, or, if the plies can be separated without damaging the specimen, a measurement can be taken on the individual plies making up the product. If a given sample differs from surface to surface, it is necessary to test both surfaces and average the values in order to arrive at a composite lint value. In some cases, products are made from multiple-plies of webs such that the facing-out surfaces are identical, in which case it is only necessary to test one surface. If both surfaces are to be tested, it is necessary to obtain six specimens for testing (Single surface testing only requires three specimens).
- Each specimen should be folded in half such that the crease is running along the cross direction (CD) of the web sample.
- CD cross direction
- the four pound weight has four square inches of effective contact area providing a contact pressure of one pound per square inch. Since the contact pressure can be changed by alteration of the rubber pads mounted on the face of the weight, it is important to use only the rubber pads supplied by the manufacturer (Brown Inc., Mechanical Services Department, Kalamazoo, Mich.). These pads must be replaced if they become hard, abraded or chipped off. When not in use, the weight must be positioned such that the pads are not supporting the full weight of the weight. It is best to store the weight on its side, iv. RUB TESTER INSTRUMENT CALIBRATION The Sutherland Rub Tester must first be calibrated prior to use. First, turn on the Sutherland Rub Tester by moving the tester switch to the "cont" position.
- the first step in the measurement of lint is to measure the Hunter color values of the black felt/cardboard samples prior to being rubbed on the web sample.
- the first step in this measurement is to lower the standard white plate from under the instrument port of the Hunter color instrument. Center a felt covered cardboard, with the arrow pointing to the back of the color meter, on top of the standard plate. Release the sample stage, allowing the felt covered cardboard to be raised under the sample port.
- the felt width is only slightly larger than the viewing area diameter, make sure the felt completely covers the viewing area. After confirming complete coverage, depress the L push button and wait for the reading to stabilize. Read and record this L value to the nearest 0.1 unit.
- a D25D2A head If a D25D2A head is in use, lower the felt covered cardboard and plate, rotate the felt covered cardboard 90° so the arrow points to the right side of the meter. Next, release the sample stage and check once more to make sure the viewing area is completely covered with felt. Depress the L push button. Read and record this value to the nearest 0.1 unit. For the D25D2M unit, the recorded value is the Hunter Color L value. For the D25D2A head where a rotated sample reading is also recorded, the Hunter Color L value is the average of the two recorded values.
- the Horizontal Full Sheet (HFS) test method determines the amount of distilled water absorbed and retained by a sanitary tissue product of the present invention. This method is performed by first weighing a sample of the sanitary tissue product to be tested (referred to herein as the "Dry Weight of the paper"), then thoroughly wetting the sanitary tissue product, draining the wetted sanitary tissue product in a horizontal position and then reweighing (referred to herein as "Wet Weight of the paper"). The absorptive capacity of the sanitary tissue product is then computed as the amount of water retained in units of grams of water absorbed by the sanitary tissue product. When evaluating different sanitary tissue product samples, the same size of sanitary tissue product is used for all samples tested.
- the apparatus for determining the HFS capacity of sanitary tissue product comprises the following: an electronic balance with a sensitivity of at least ⁇ 0.01 grams and a minimum capacity of 1200 grams.
- the balance should be positioned on a balance table and slab to minimize the vibration effects of floor/benchtop weighing.
- the balance should also have a special balance pan to be able to handle the size of the sanitary tissue product tested (i.e.; a paper sample of about 11 in. (27.9 cm) by 11 in. (27.9 cm)).
- the balance pan can be made out of a variety of materials. Plexiglass is a common material used.
- a sample support rack and sample support cover is also required. Both the rack and cover are comprised of a lightweight metal frame, strung with 0.012 in. (0.305 cm) diameter monofilament so as to form a grid of 0.5 inch squares (1.27 cm 2 ). The size of the support rack and cover is such that the sample size can be conveniently placed between the two.
- the HFS test is performed in an environment maintained at 23 ⁇ 1° C and 50 ⁇ 2% relative humidity.
- a water reservoir or tub is filled with distilled water at 23 ⁇ 1° C to a depth of 3 inches (7.6 cm).
- the sanitary tissue product to be tested is carefully weighed on the balance to the nearest 0.01 grams. The dry weight of the sample is reported to the nearest 0.01 grams.
- the empty sample support rack is placed on the balance with the special balance pan described above. The balance is then zeroed (tared). The sample is carefully placed on the sample support rack. The support rack cover is placed on top of the support rack. The sample (now sandwiched between the rack and cover) is submerged in the water reservoir. After the sample has been submerged for 60 seconds, the sample support rack and cover are gently raised out of the reservoir.
- the sample, support rack and cover are allowed to drain horizontally for 120 ⁇ 5 seconds, taking care not to excessively shake or vibrate the sample.
- the rack cover is carefully removed and the wet sample and the support rack are weighed on the previously tared balance. The weight is recorded to the nearest 0.0 Ig. This is the wet weight of the sample.
- the gram per sanitary tissue product sample absorptive capacity of the sample is defined as (Wet Weight of the paper - Dry Weight of the paper).
