METHOD OF MAKING ABSORBENT FOAM COMPOSITES |
摘要 |
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. |
