COMPRESSED CATAMENIAL TAMPON WITH IMPROVED CAPABILITIES FOR ABSORBING MENSTRUAL FLUIDS |
摘要 |
This invention is directed to a compressed catamenial tampon made up of a mass of absorbent fibers having intermixed therein a quantity of carboxymethylcellulose fibers containing free-acid carboxyl radicals and characterized by a high capacity for absorbing and retaining menstrual fluids. These carboxymethylcellulose fibers are modified by heat treatment to shorten the time it takes for such fibers to absorb a specified amount of fluid and thereby more effectively utilize their high capacity. The particular high capacity fibers are defined as carboxymethylcellulose fibers having a degree of substitution in the normally soluble range of about 0.4 to about 2.0 in which a part of the carboxyl groups are in free-acid form with the remainder in salt form. |
