  • a third method of imparting gathers or puckers to the composite 10 involves stretching one of the layers and bonding it to the other layer with the other layer being made from a heat shrinkable material. Once the two layers are bonded, the tension in the stretched layer can be relaxed and heat can be applied to the composite thereby providing two means within the same composite for creating gathers or puckers. If desired, the direction of orientation of the heat shrinkable material can be parallel with or skewed from the direction of stretching in the other layer to provide gathering or puckering in one or more directions.
  • a fifth way to impart gathers or puckers to the material of the present invention would be to use elastic threads sandwiched between and bonded to the film layer 12 and substrate layer 14.
  • the elastic threads would be stretched or elongated prior to their adhesion or bonding between and to the two layers. Once the bonding had been completed, the elastic threads would retract thereby gathering and puckering the composite material 10 of the present invention.

  • Air permeability was measured using the Frazier porosity test. Air permeability is the rate of air flow through a material under a pressure differential between two fabric surfaces. Samples were tested on a Frazier Air Permeability Tester available from Frazier Precision Instrument Company of Gaithersburg, Maryland. The procedures used conformed to the specifications of Method 5450, Federal Test Methods Standard 191A except that the specimen size was 8 inches ⁇ 8 inches (20.3 ⁇ 20.3 cm) rather than 7 inches ⁇ 7 inches (17.8 ⁇ 17.8 cm). The larger size made it possible to ensure that all sides of the specimen extended well beyond the retaining ring and facilitated clamping of the specimen securely and evenly across the orifice. In the procedure, air was drawn through the specimen and a calibrated orifice using a suction fan.
  • the rate of air flow through the fabric was adjusted to obtain a pressure differential of 0.51 inches (13 mm) of water between the two surfaces.
  • the amount of air flowing through the specimen was determined from the drop in pressure across a calibrated orifice as indicated by a vertical oil manometer. This reading was converted to an air flow rate using a conversion table provided by the manufacturer of the instrument. The results were expressed in cubic feet of air per square foot of specimen per minute or in cubic centimeters per square centimeter per second. The higher the number, the more permeable or porous the material.
  • a trapezoid tear test was conducted. This test was a measure of the tearing strength of a material or materials when a constantly increasing load was applied parallel to the length of the specimen. The test can be conducted on a constant rate of extension tester such as an Instron, model TM available from Instron Corporation of Canton, Massachusetts or a Thwing-Albert, Model INTELLECT II tester available from Thwing-Albert Instrument Company of Philadelphia, Pennsylvania.

  • the surface smoothness of a material is another important feature of a material if the material is to be used as a body contacting layer as is the case with the present material when used as a liner for a sanitary napkin.
  • the surface smoothness of the materials described herein was tested by measuring the coefficient of friction of the surface when contacted with a sensor plate drawn across the surface of the material. Values between materials were then compared to establish a relative scale for purposes of evaluation. Higher coefficients of friction corresponded to rougher surfaces.
  • a fluid run-off test was performed to measure the ability of a material to absorb a liquid.
  • a 3 inch by 7 inch sample of the material was placed at a 30° incline and 5cc of synthetic menstrual fluid was then applied to the surface over a 3 second period.
  • the amount of fluid which was not absorbed and therefore ran off the end of the sample was measured in grams. The lower the gram reading and thus the run-off, the higher was the degree of absorption of the material.
  • the adhesion level between the film layer and the substrate layer is also important.
  • an adhesion test was performed. For each sample, the cohesion force of a 1 inch square sample was measured using a Chatillon Digital Force Gauge Model DFI 50 from John Chatillon and Sons, Inc., of Greensboro, North Carolina. The device has a pneumatically operated base plate measuring 2 inches by 4 inches and a one inch square top plate vnicn was connected to a digital force gauge. Double-faced adhesive tape was applied to both the base plate and the top plate and a 2 inch by 4 inch sample of material was positioned cn top of the 2 inch by 4 inch base plate.

  • the film had a slit density of 19 inches of slits per square inch (7.48 cm/cm 2 ) of film.
  • the substrate layer in Example I was a fibrous bicomponent spunbond web made in the manner described above. Fiber sizes ranged between 3 and 5 denier (21.9 and 28.2 microns) and the fibers due to the use of the spunbond process were essentially continuous in length. By “continuous” it is meant that the ratio of fiber length to width approached infinity.
  • the bicomponent fibers were a side-by-side construction using polyethylene and polypropylene.
  • the polyethylene was Grade 6811 from Dow Chemical, U.S.A. of Midland, Michigan and the polypropylene was Grade 3445 from Exxon Chemical Company of Darien, Connecticut. Basis weights ranged between 1 and 1.5 ounces per square yard (osy) (34-51 gsm) and the webs were through air bonded.
  • the nonwoven substrate layer was treated with Y12488 surfactant from Union Carbide of Tarrytown, New York. This is a non-ionic surfactant wetting packaging which references U.S. Patent No. 5,057,361.
  • the surfactant was added in spray form and the treated nonwoven web had an add on of 0.4 percent surfactant based upon the total dry weight of the nonwoven web.
  • the nonwoven layer Prior to bonding the two layers together, the nonwoven layer was stretched between 5 and 20 percent due to the speed differential of the rolls. See the process description above. As an example, a material that was originally 100 inches (254 cm) in length and which was then stretched to 120 incnes (305 cm) would be stretched 20 percent.
  • the film and substrate layers were point bonded to one another using conventional ultrasonic equipment from Branson Sonic Power Corp of Danbury, Connecticut using a model #501 series bonder.
  • the relative energy was 65 and the line speed at the point of bonding was 12 feet per minute (3.7 meters per minute).

While again depending upon the particular end use application, for personal care applications calipers of at least about 0.035 inches (0.15 mm) are desirable so as to prevent rewet of the film layer 12 by already absorbed exudate contained within the absorbent core of the personal care structure.
  • Example 2 four sample materials according to the present invention were prepared and compared against two controls.
  • the first control was a KOTEX ® Maxi Pad sanitary napkin manufactured by the assignee of record.
  • the napkin had a polypropylene spunbond nonwoven cover.
  • the second control was an ALWAYS ® sanitary napkin manufactured by the Procter and Gamble Company of Cincinnati, Ohio.
  • the ALWAYS ® sanitary napkin had an apertured film cover.
  • the film and substrate layers were bonded to one another using heat and pressure via a pair of patterned and anvil bond rolls.
  • the patterned roll was heated to 140°F (60°C) and the anvil roll was heated to 160°F (71oC).
  • the bond pressure at the nip was 20 pounds per square inch (6.8 kg/cm 2 ) and the two layers were bonded to one another at a rate of 10 feet per minute (3 m/min) using a point bond pattern with an overall bond area of 8%.
  • the exposed sides of the nonwoven and film layers were hand sprayed with a surfactant solution of Gemtex SM-33 surfactant from Finetex, Inc. of Elmwood Park, New Jersey at an add-on of 0.6% based on the weight of the composite.
  • Example 2 three samples according to the present invention were prepared all of which used the same substrate layer.
  • the substrate layer was made in the same fashion as Examples 1 and 2 using 5 denier polyethylene/polypropylene side-by-side bicomponent fibers.
  • the substrate layer had a basis weight of 1.5 ounces per square yard (51 gsm) and was treated with 0.4% of the same surfactant used in Example 1.
  • Example 4 the film and substrate layers used were the same as in Example 2. The difference between Example 4 and Example 2 was in the slit pattern used to slit the film layer.
  • Example 4 a herringbone design similar to that shown in Figure 2 was used. The herringbone design yielded an average slit length per square inch of 16.3 in/in 2 (6.4 cm/cm 2 ).
  • 10 grams per square meter of a 34-5541 hot-melt adhesive from the National Starch Company of Cincinnati, Ohio was applied in continuous spray pattern across the width of the nonwoven layer. Prior to bonding the two layers together, the film layer was stretched in the machine direction and the percent stretch was calculated to be 5%.
  • Example IV After forming the sample, it was hand-sprayed with 0.6%, based upon the dry weight of the composite, with Gemtex SM-33 surfactant on the exposed sides of the film and substrate layers. Fluid handling properties including bulk, intake and rewet rates were measured and are given below in Table VI below. Relative to the two controls, the sample in Example IV had a much better intake rate and far less rewet. In addition, there was no run-off of synthetic menses with the herringbone slit design. Lastly, it should be noted that the same good fluid handling properties were achieved using an adhesively laminated composite instead of a thermally laminated composite.
