ABSORBENT MATERIAL FOR WATER, AQUEOUS SOLUTIONS AND AQUEOUS BODY FLUIDS

摘要

An absorption material is produced by applying directly to a support in the presence of liquid an absorbent which is at least partially water-softened, and drying to remove the liquid so as to leave the absorbent directly on the support. The support may be fibrous or particulate like sawdust or it may be a textile sheet or paper. The absorbent may be an acrylic based polymer. Because the absorbent directly contacts the support the product has increased absorptive capacity and is stronger, making it especially useful as a diaper, tampon, sanitary napkin, surgical dressing, battery separator and/or filter for cigarette smoke or for liquids.
