Definitions

  • This invention is directed to laminates of extensible nonwoven material and elastomeric material that are bonded using both intermittent adhesive bonds and thermal point bonds wherein the adhesive bonds cover a greater percentage of an interfacial plane between the extensible nonwoven material and the elastomeric material than the thermal bonds.
  • the resulting extensible laminates exhibit increased elasticity in the cross direction compared to laminates in which the elastomeric material is fully bonded to the extensible nonwoven material. Additionally, the resulting laminates exhibit desirable surface aesthetics due to the pattern created by the thermal point bonds.
  • a process for making the extensible laminates that provides greater flexibility in the manufacturing process is also disclosed.
  • Composites of elastic and nonelastic material have been made by bonding the elastic material to the nonelastic material in a manner that allows the entire composite to stretch or elongate. Often these composites are used in garment materials, pads, diapers, adult incontinence products and feminine care products.
  • One such composite or laminate includes an extensible nonwoven material that has been bonded to an elastomeric sheet.
  • the layers of the laminate may be bonded together using a variety of techniques including thermal bonding, adhesive bonding and point bonding which may also be thermal.
  • Thermal bonding techniques include extruding a molten elastomeric material in the form of a film onto the extensible nonwoven web. The film and the nonwoven material are then smooth calendered to bond the two layers together.
  • Thermal bonding techniques also include passing a cast elastomeric film or a meltblown elastomeric web and an extensible nonwoven material web through heated smooth calender rolls to affect bonding. However, in both cases, the elastomeric material is substantially fully bonded to the nonwoven thereby increasing the extension force and set and decreasing the retraction force/extension force ratio.
  • Adhesive bonding techniques achieve similar results.
  • an adhesive typically a hot melt or molten type adhesive or a pressure sensitive adhesive
  • the layers are then calendered to achieve bonding.
  • the layers of the resulting laminate may be fully attached or selectively attached to each other.
  • Point bonding techniques which may be thermal, may also be used to join the layers of the laminate. Point bonding techniques generally involve the mechanical forcing of portions of one layer into areas of a second layer such that portions of the first layer become entrapped in the second layer thereby bonding the layers together.
  • the elastomeric material is in a molten or near-molten state in order to achieve effective bonding between the layers of material.
  • the elastomeric material may also be softened by heating the patterned and/or smooth calender roll.
  • An example of a process for point bonding a nonwoven material to an elastomeric sheet is disclosed in U.S. Pat. No. 6,001,460 to Morman et al., the disclosure of which is hereby incorporated by reference.
  • Adhesive bonding provides greater flexibility in the manufacturing process because a wide variety of adhesives, such as, for example, inelastic, elastomeric, pressure sensitive, melt blown or hot melt adhesives, may be utilized to bond a greater variety of materials. Additionally, adhesive bonding may be more cost effective and less process and material limiting than thermal bonding. Furthermore, adhesives can be applied in a wide variety of patterns capable of mimicking point bond patterns without the use of expensive calender or embossing rolls. This feature also makes it possible to change the adhesive bond pattern quickly during production such that different patterns and/or levels of adhesive bond coverage can be achieved during a single production run.
  • adhesives such as, for example, inelastic, elastomeric, pressure sensitive, melt blown or hot melt adhesives
  • the term “extensible” refers to a material that can be stretched without breaking by at least 50% (to at least 150% of its initial unstretched length) in at least one direction, suitably by at least 100% (to at least 200% of its initial unstretched length).
  • an extensible material having an initial unstretched length of 3 inches may be stretched without breaking to at stretched length of at least 4.5 inches in at least one direction.
  • the term includes elastic materials as well as materials that stretch but do not significantly retract such as, for example, necked nonwoven materials and inherently extensible nonwoven materials like bonded carded webs.
  • the terms “elastic” and “elastomeric” mean a material which upon application of a biasing force, is stretchable to a stretched, biased length that is a least about 150 percent of its relaxed, unstretched length, and which will recover at least 55 percent of its elongation upon release of the stretching, biasing force within about one minute.
  • the term “recover” refers to a contraction of a stretched material upon termination of a biasing force following stretching of the material by application of the biasing force. For example, if a material having relaxed, unbiased width of 1 inch is extended 50 percent in the cross direction by stretching to a width of 1.5 inches the material would be extended 50 percent (0.5 inch) and would have a stretched width that is 150 percent of its relaxed width. If this exemplary stretched material relaxed, and recovered to a width of 1.1 inches after release of the biasing and stretching force, the material would have recovered 80 percent (0.4 inch) of its 0.5 inch extension. Recovery may be expressed as [(maximum stretched dimension minus final sample dimension)/(maximum stretched dimension minus initial sample dimension)] ⁇ 100.
  • biaxially extensible refers to a material that may be stretched by at least about 50% in two directions perpendicular to each other (e.g. stretchable in a machine direction and cross direction, or in a longitudinal direction, front to back, and a lateral direction, side to side).
  • the term includes biaxially extensible laminates such as those disclosed in, for example, U.S. Pat. Nos. 5,114,781 and 5,116,662 to Mornan, which are incorporated by reference.
  • machine direction means the length of a material in the direction in which it is produced.
  • cross direction means the width of a material, (e.g., a direction generally perpendicular to the machine direction).
  • polymer generally includes, but is not limited to, homopolymers, copolymers, such as for example, block, graft, random and alternating copolymers, terpolymers, etc. and blends and modifications thereof.
  • polymer shall include all possible geometrical configurations of the material. These configurations include, but are not limited to, isotactic, syndiotactic and random symmetries.
  • elastomeric sheet and “elastomeric web” refer to elastomeric films formed by extrusion, casting or other methods known in the art, as well as, elastomeric nonwoven fabrics such as, for example, meltblown elastomeric webs as disclosed in U.S. Pat. No. 4,663,220 to Wisneski et al., which is incorporated by reference, and elastomeric foams.
  • metallocene refers to polyolefins produced by metallocene-catalyzed polymerization reactions. Such catalysts are reported in “Metallocene Catalysts Initiate New Era in Polymer Synthesis”, Ann M. Thayer, Chemical & Engineering News, Sep. 11, 1995, p. 15.

Most suitably, the elastomeric intermittent adhesive bonds 20 may cover from about 10 percent about 50 percent of the interfacial plane 22 . Desirably, at least about 30 percent to about 70 percent of the interfacial plane is free of elastomeric intermittent adhesive bonds.
  • the extensible nonwoven material sheet 12 is further selectively attached to the elastomeric sheet 14 by a plurality of thermal point bonds 24 .
  • the thermal point bonds 24 may be formed through the use of heat and pressure to force portions of then extensible nonwoven material sheet 12 into areas of the elastomeric sheet 14 such that the portions of extensible nonwoven material sheet 12 are encapsulated by areas of the elastomeric sheet 14 .
  • Such thermal point bonds are formed, generally, by passing the two sheets of material through a nip between a pair of heated laminating rolls. At least one of the laminating rolls is engraved such that it has a pattern of protrusions or pins that form the point bonds as the sheets are pressed between the rolls.
  • the other laminating roll may be smooth or it may also be patterned. If the second roll is patterned, the pattern may match the first roll pattern such that the thermal point bonds on each side of the laminate overlay one another. Alternatively, the patterns may be offset such that the two sides of the laminate display different bonding patterns.
  • the two rolls could also have spiral patterns with opposite pitch such that the bonding occurs only where the two spirals meet.
  • the thermal point bonds 24 may be formed using ultrasonic bonding or welding techniques.
  • this type of thermal point bond is formed by passing the two sheets of material through a nip between an ultrasonic bonding horn and an ultrasonic bonding anvil. At least one of the horn and the anvil is engraved or patterned such that it has protrusions that form the thermal point bonds as the sheets are exposed to ultrasonic sound waves.
  • the thermal point bond coverage may be calculated by multiplying the pin density, expressed as pins per area, by the area of the pins. For example, a patterned roll including a plurality of pins having an area of 0.01 square centimeters per pin and having a pin density of 30 pins per square centimeter would provide a thermal point bond coverage of 0.30 or 30 percent.
  • the thermal point bonds 24 can be positioned in the interfacial plane between the intermittent adhesive bonds 20 .
  • at least a portion of the thermal point bonds 24 can overlay at least a portion of the intermittent adhesive bonds 20 .
  • the thermal point bonds 24 may cover from about 5 percent to about 50 percent of the interfacial plane. More suitably, the thermal point bonds 24 may cover from about 10 percent to about 40 percent of the interfacial plane 22 .
  • at least about 50 percent of the interfacial plane 22 is free from thermal point bonds 24 .
  • the intermittent adhesive bonds 20 and the thermal point bonds 24 may be positioned in the interfacial plane 22 as alternating stripes or bands of thermal point bonds and intermittent adhesive bonds as shown in FIG. 4.
  • the stripes or bands may be oriented in the cross-direction, the machine direction, on a diagonal across the interfacial plane, or other suitable pattern.
  • the individual stripes or bands may have the same or different dimensions such as length and/or width. Additionally, the individual stripes or bands of bonds may be spaced apart from each other by a bond-free stripe or band in the interfacial plane 22 .
  • the stripes or bands may be configured in any suitable pattern to provide the desired bond coverage.
  • the intermittent adhesive bonds 20 cover a greater percentage of the interfacial plane 22 than the thermal point bonds 24 .
  • At least about 30, suitably, at least about 50 percent of the interfacial plane is free of both inelastic intermittent adhesive bonds and thermal point bonds (when the adhesive is inelastic). More suitably, at least about 60 percent of the interfacial plane is free of both inelastic intermittent adhesive bonds and thermal point bonds. Desirably, at least about 30 percent of the interfacial plane is free of both elastomeric intermittent adhesive bonds and thermal point bonds (when the adhesive is elastic). More desirably, at least about 35 percent of the interfacial plane is free of both elastomeric intermittent adhesive bonds and thermal point bonds.
  • At least about 50 percent of the interfacial plane is free of both elastomeric intermittent adhesive bonds and thermal point bonds.
  • at least about 30 percent of the interfacial plane 22 should be free of all adhesive and thermal bonds.
  • the thermal point bonds 24 impart surface patterning to the fabric side 18 of the extensible nonwoven material 12 that is aesthetically desirable.
  • the bond pattern can be applied either evenly or unevenly to the fabric side 18 of the extensible nonwoven material 12 .
  • An evenly applied bond pattern contributes to more consistent material properties across the surface of the resulting extensible laminate, while an unevenly applied bond pattern can affect material properties such as the level of retractive force.
  • H&P Hansen Pennings
  • the H&P pattern has square point or pin bonding areas wherein each pin may have a side dimension of 0.038 inches (0.965 millimeters), for example, resulting in a pattern having a bond coverage of about 30 percent.

  • Other common patterns include a “Ramisch” diamond pattern with repeating diamonds having a bond coverage of from about 8 percent to about 14 percent and 52 pins per square inch and a “S” weave pattern as described in commonly assigned U.S. Pat. No. 5,964,742 to McCormack et al., which is incorporated by reference.
