    Abstract: An elastomeric laminate that does not require mechanical activation comprises an elastomeric polymer film layer bonded to one or more other substrate layers. The elastomeric film composition, physical properties of the substrate, and bonding conditions are selected and controlled to form an elastomeric laminate that is stretchable and recoverable without the use of excess material or post-lamination mechanical activation. The resulting elastomeric laminate may be manufactured on relatively simple high-speed equipment at lower cost and with improved physical properties.

  • Patent number: 7674733
    Abstract: In one embodiment, a breathable, incrementally stretched elastic composite material comprises an inner elastomeric film extrusion-laminated to an outer nonwoven web at each film surface. The inner elastomeric film has a random pattern of incremental stretch-formed macroholes therein and is substantially free of pore-forming filler. In another embodiment, a breathable, incrementally stretched elastic composite material comprises an elastomeric film extrusion-laminated to a nonwoven web at one or both of the film surfaces. The elastomeric film has a random pattern of incremental stretch-formed macroholes therein and is substantially free of pore-forming filler. Methods of manufacturing the composite materials comprise extrusion laminating and incremental stretching. Garments and disposable articles are formed at least in part from the composite material.

  • Patent number: 7629278
    Abstract: The presently described technology provides a low cost multilayer elastomeric film containing at least one layer of styrene block copolymer and at least one elastomer layer substantially free of styrene block copolymer such that the resultant film has a low permanent set substantially equal to or less than a film comprised of styrene block copolymer only. The elastomeric film may be used in elasticized features of various articles, such as disposable absorbent articles. Methods for producing the low cost elastomeric film having a low permanent set are also described.

  • Patent number: 7629277
    Abstract: Fabric laminates having superior resistance to penetration of fragments, such as shrapnel. The fabrics are formed of high-strength fibers consolidated with from about 7% to about 15% by weight of an elastomeric matrix composition, and in combination with protective layers of a polymer film on each surface of the fabric. The fabrics achieve a significant improvement in fragment resistance compared to fabrics of the prior art, while also maintaining excellent ballistic resistant properties.

  • Patent number: 7625829
    Abstract: An elastomeric film is bonded between two or more layers of nonwoven webs formed of nonelastomeric thermoplastic fibers. The laminate has, in a predefined transverse direction, an elastic elongation value greater than the predefined elastic elongation value of the nonwoven webs, and an ultimate force to break in the predefined transverse direction of at least 3000 g/in. The laminate advantageously provides a tear resistant, multiple ply, fabric that is soft to the touch as a result of the outwardly disposed nonwoven webs, and has a high elastic modulus. The laminate is particularly useful in applications where closure portions of a product must be stretched to keep the product in place when worn.

  • Patent number: 7612001
    Abstract: An elastic laminate having improved elastomeric properties is prepared by forming an elastic layer from a thermoplastic styrene block copolymer elastomer, crosslinking the elastic layer, and bonding the elastic layer to at least one nonwoven web. The elastic layer may be crosslinked before or after it is bonded to the nonwoven web. The elastic laminate combines the advantages of relatively low cost starting materials with the performance advantages typically associated with more expensive elastomers.
