  • Patent number: 9744755
    Abstract: A method of making absorbent foam composites and absorbent foam composites produced therefrom. The method comprises casting an absorbent foam layer having a first side and a second side opposite the first side onto a barrier layer having a first side and second side opposite the first side, where the second side of the absorbent foam layer is in contact with the first side of the barrier layer; joining a second absorbent layer to the second side of the barrier layer before, during, or after the casting step; and breaching the barrier layer after the casting step so that the foam layer and second absorbent layer are in fluid communication. The absorbent foam composites can be used in a variety of applications, including personal hygiene articles, medical bandages, pet pads and agricultural pads.

  • Patent number: 9572722
    Abstract: Provided are adhesive articles and assemblies that include a flat and at least partially elastic backing along with a patterned adhesive coating on each side of the backing. When viewed from directions perpendicular to the backing, the adhesive on one side of the backing does not substantially overlap the adhesive on the opposing side of the backing. As a result, it is possible to use a stretch removable adhesive article that uses, for example, an aggressive adhesive to provide a reliable bond but still remove cleanly and easily from delicate substrates that would otherwise be damaged or destroyed if bonded with conventional adhesive constructions.
