Abstract
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.degree. C. to 100.degree. 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.
