Abstract: The cloth-like, liquid impervious composite material is made by applying a nonwoven layer of loose, unadhered fibers to a liquid impervious film, and then point-bonding the nonwoven layer to the liquid impervious film to form discrete points of adhesion between the fibers and film. Because the fibers in the nonwoven layer are loose and unadhered when applied to the film, the resulting composite material has improved loft and softness. Also, when the composite material is elasticized by an elastic material, it gathers into a more pleasing appearance.

The wet substrate is preferably used in conjunction with a dispenser having a relatively tight closure, especially one in which the closure is formed by two resilient diaphragms with out-of-register apertures. The wet substrate delivery system may be used, for example, for hand hygiene in hospitals, washrooms or kitchens.

Abstract: A felting of synthetic fibers having an embossed pattern that forms depressions in at least one surface of the felting is disclosed. The surface of the felting with depressions contains, in at least the area of the depressions, a layer of small hollow spheres that are bonded to one another and to the felting by means of a binding agent.

Furthermore, the excessive penetration of adhesive into the felting, which can cause a spotty or uneven appearance of the reinforced upper, is prevented. Resistance to splitting and separating is likewise improved.
