Method for increasing the absorbency of cellulosic fibers by a high temperature wet treatment comprising heating the fibers in a water bath at temperatures within the range of about 95°C. to 100°C. for periods ranging from about one to sixty minutes.

Method for increasing the absorbency of cellulosic fibers by a high temperature wet treatment comprising heating the fibers in a water bath at temperatures within the range of about 95°C. to 100°C. for periods ranging from about one to sixty minutes. Absorbency of the treated fibers is thus increased by more than 2% of the corresponding untreated fibers as measured by the Syngyna Test Method. By employing such materials in catamenial tampons, sanitary napkins or the like, the amount of absorbent material may be decreased by 10% or more relative to the corresponding, untreated absorbent material, without adversely affecting the absorbent characteristics thereof.

A method for increasing the absorbency of processed cotton or other processed non-regenerated cellulosic fibers, comprising: (a) heating, by a high temperature wet treatment, the cellulosic fibers in the presence of water at a temperature within a range of 95°C.-100°C. for a period in a range of one to sixty minutes; and (b) treating the fibers with water at a temperature from about 20°C. to about 25°C. for a period of from approximately 5 to 10 minutes, to increase the absorbency of the treated fibers by at least 2% of the absorbency of the corresponding untreated fibers as measured by the in vitro Syngyna Test Method.
