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.

Abstract: A three-dimensional film for use as an acquisition distribution layer in an absorbent article comprising a first surface with drains extending downward from the first surface, the drains being capable of transmitting fluid by gravity; and protrusions extending upward from the first surface to an upper surface with at least one capillary extending downward from the upper surface, the capillaries being capable of transmitting fluid in contact with the upper surface by capillary action. The drains rapidly transmit fluid through the film, particularly fluid that is dynamically-deposited. The capillaries transmit statically-retained fluid that is in contact with the upper surface of the protrusions.
Abstract: A method for manufacturing composite webs and composite webs made thereby in which the web includes a perforated thermoplastic film and one or more nonwoven webs. The method provides a perforated thermoplastic film, a creped nonwoven web, the webs are fed in a face to face relationship to be bonded. The perforated thermoplastic film and the creped nonwoven web are bonded in a face to face relationship at a plurality of points of contact such that the creped structure of the nonwoven web is maintained and the composite web has a nonwoven face and a film face. The composite webs are extensible at least in the direction of the creping.
