ABSTRACT OF THE DISCLOSURE An absorbent web structure is disclosed which is composed of a mixture of 5 to 50% by weight of short fibers of a thermoplastic resin rendered hydrophilic with a surface-active agent and 95 to 50% by weight of cellulosic fibers. The thermoplastic short fibers are melt-bonded to impart self-supporting property to the web structure and are rendered hydrophilic by forming an aqueous slurry of the fibers containing a nonionic surface- active agent and then dehydrating the slurry. The nonionic surface-active agent has an HLB value of from 2 to 20 and a melting point equal to or higher than the temperature of the slurry at the time of dehydrating treatment. The resultant structure exhibits good mechanical strength and excellent absorbing properties when used as disposable diapers, sanitary napkins, medical sponges, wound-treating pads or towels.
