ABSTRACT:
A method for making a breathable elastomeric laminar fabric, the material produced thereby and a disposable absorbent garment incorporating the material as either an outer cover or gathers at the leg and waist openings. The method comprises the steps of sandwiching a liquid impermeable elastomeric film or nonwoven carrier sheet between a pair of nonwoven facing sheets while the carrier sheet is in at least a partially stretched condition and bonding the facing sheets together through the carrier sheet at spaced apart sites, simultaneously forming breathable apertures while laminating the carrier and facing sheets together at the spaced apart sites. Creped facing sheets may also be used and bonded together while the film is in a partially stretched or unstretched condition.
