Abstract
Absorbent laminates include an oriented, fluid-pervious plastic substrate bonded to a nonwoven absorbent member. The nonwoven absorbent member includes bi-component fibers having a heat-softenable outer skin, said heat-softenable outer skin being heat-softenable at a temperature lower than the melting point and shrinking point of the oriented plastic substrate to provide a binder component for the laminate. A fluid-pervious plastic substrate can be adhered to one or both surfaces of the nonwoven absorbent member through bi-component fibers of the nonwoven absorbent member. In absorbent laminates including opposed fluid-pervious outer plastic substrates marginal edges of the laminate can be compression sealed through the bi-component fibers in the intermediate nonwoven absorbent member to seal the edges against the escape of fibers from the laminate. Methods of forming absorbent laminates of this invention also form a part of the present invention.
