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.
An absorptive device for incontinent patients comprising a liquid permeable absorptive member having an outer facing layer of interconnected synthetic thermal plastic fibers and an inner backing layer with a material blend of interconnected synthetic thermal plastic and cellulosic fibers, the synthetic thermal plastic fibers of outer facing layer being ultrasonically welded to the synthetic thermal plastic fibers of the blended material inner backing layer to join the layers together while allowing liquid communication throughout the layers, the synthetic thermal plastic fibers of the outer facing layer being ultrasonically welded to the thermal plastic fibers of the blended material inner backing layer at intermittent locations in a predetermined configuration representing a quilt pattern throughout, a liquid impervious barrier member underlying the liquid permeable absorptive member to restrict the flow of liquid therethrough, and a liquid impervious side binding member which overlaps and binds the liquid permeable absorptive member and liquid impervious barrier member to one another along free end surfaces thereof and also including outwardly facing surface portions immediately adjacent to said free end surfaces to inhibit side leakage of liquid.
