ABSTRACT:
An absorptive device for incontinent patients is disclosed as including a liquid permeable absorptive member having an outer facing layer of synthetic fabric and an inner backing layer of fabric having a blend of thermal plastic and cellulosic fibers, the synthetic outer facing layer being ultrasonically welded to the thermal plastic fibers of the blended material inner backing layer, and a liquid impervious barrier member underlying the liquid permeable absorptive member to restrict the flow of liquid therethrough. The ultrasonic welding is performed at intermittent locations in a predetermined configuration representing a quilt pattern. A liquid impervious side binding member overlaps and binds the free end and immediately adjacent surfaces of the absorptive and barrier members to inhibit side leakage. The liquid impervious barrier member includes a thermal plastic film of liquid impervious material sandwiched between two fabrics which are then bonded to one another.
