An improved disposable diaper of the type having a relatively high elongation to tensile force property, an absorbent pad, and tape-tab fasteners coated with a peelable adhesive. The backsheet is reinforced by coating the mother's bond region thereof with a material having high tensile strength and a low elongation to tensile force property relative to the backsheet material. The coating may be continuous or patterned and may be disposed on either the outwardly facing surface or the inwardly facing surface of the mother's bond region of the backsheet. When applied to the inwardly facing surface, the coating material may be adhesive material and may secure the backsheet to the pad assembly of the diaper. The reinforcement of the backsheet improves the resistance of the backsheet to stretching and tearing when subjected to tensile forces during fastening and wearing, and to peeling forces when the tape-tab fasteners are being peeled open. Thus, the fasteners are refastenable.

Soft, absorbent, bulky paper web useful in tissue, towel, sanitary, and like products. The web is formed by supplying an aqueous furnish which includes thermomechanically defibrated pulp in admixture with chemically defibrated pulp to a foraminous surface such as a Fourdrinier wire, transferring the moist web to an imprinting fabric, thermally drying the web without mechanical compression to a consistency of from about 30 percent to about 98 percent, imprinting the pattern of the fabric into the thermally predried web, and finally drying the web. The resulting web has relatively high tensile strength at relatively low density. Also, the strength properties of the web are significantly improved if the thermomechanically defibrated pulp is made from wood chips which have been soaked in chemical solutions prior to defibrating and then treated with ozone after defibrating.
