ABSTRACT:
A nonwoven absorbent structure usable by itself, as a wiper for example, or usable in combination with other elements, such as an internal absorbent member of a disposable diaper. The absorbent structure includes a dry-formed fibrous section in which the average fiber length is about 1.2 millimeters or longer, and a liquid-transmitting layer of particulate material associated with at least one surface of the fibrous section and having a density greater than that of the fibrous section. At least 50% of the particles, by weight, are of a size that will pass through a 48 mesh screen, and the particulate material is chemically bonded together to form the liquid-transmitting layer(s). Particles of the layer(s) are located between fibers at and adjacent the associated surface(s) of the fibrous section to form a zone in which particles and fibers are intermixed. A disposable diaper in accordance with this invention has an internal absorbent member including a dry-formed fibrous section with the above-described layer of particulate material associated with only one surface thereof. The absorbent member is positioned between a liquid-pervious facing sheet and a backing sheet, and the layer of particulate material is associated with the surface of the fibrous section closest the backing sheet.
