  • 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: 7378568
    Abstract: An absorbent article having a topsheet and an absorbent core material. The acquisition distribution layer is located between the topsheet and the absorbent core material. The acquisition distribution layer is made of a three dimensional apertured film that defines a large void volume space between the acquisition distribution layer and the absorbent core material. The acquisition distribution layer provides high void volume for lateral spillage during repeated insult moments because the topsheet, which is in contact with the user, is held away from dispersing fluid that is unabsorbed by saturated core material. The void volume space provides a pathway for unabsorbed fluid to flow over the top plane of saturated core regions to unsaturated regions of the core material for absorption. The void volume space allows this migration of fluid to occur without the fluid coming into contact with the topsheet, thereby avoiding a feeling of wetness for a wearer.
