Abstract
Curled, twisted cellulosic fibers are reduced in size by mechanical means, i.e., by refining. The refined fibers are formed into sheets which are used as an absorbent layer in diapers, bandages and, especially, in sanitary napkins. In one mode, the refined fibers can be used to provide shaped sanitary devices. In an optional mode, fibers having intra-fiber capillary channels can be used to direct fluids into absorbent sheets comprising the refined, curled cellulosic fibers.
