The inner surfaces of the first and second plies are adhered at their interface by a flexible, soft latex binder. The binder is adhered to substantially all fibers exposed on the inner surfaces of the first and second plies. The binder is present in the first ply from its inner surface to a depth of from about 20% to about 80% of its thickness, and is present in the second ply from its inner surface to a depth of from about 20% to about 80% of its thickness.

摘要： Individualized, crosslinked fiber, and process for making such fibers. The individualized, crosslinked fibers have between about 0.5 mole % and about 3.5 mole % crosslinking agent, calculated on a cellulose anhydroglucose molar basis, reacted with fibers in the form of intrafiber crosslink bonds, wherein the crosslinking agent is selected from the group consisting of C.sub.2 -C.sub.8 dialdehydes, C.sub.2 -C.sub.8 dialdehyde acid analogues having at least one aldehyde functionality, and oligomers of such C.sub.2 -C.sub.8 dialdehydes, and dialdehyde acid analogues. Preferably, the crosslinking agent is glutaraldehyde, and between about 0.75 mole % and about 2.5 mole % crosslinking agent react to form the intrafiber crosslink bonds. The individualized crosslinked fibers are useful in a variety of absorbent structure applications.

摘要： A nonwoven disposable towel, having particular utility as a surgical towel, comprising a five-ply structure and method of making it. The outermost plies of the towel are tissue. To each of these tissue plies there is adhered an intermediate ply constituting a medium density, thermoplastic, long fibered, nonwoven material. These tissue-intermediate ply assemblies comprise primary laminates accounting for four plies of the towel. Between these primary laminates there is located a fifth or center ply constituting a low density, melt blown, long fibered, nonwoven material. The entire structure is heat sealed about its periphery and additional spot heat bonds may be employed to minimize slippage between the center ply and the two primary laminates. The two primary laminates may be embossed prior to assembly of the towel.

摘要： An absorbent article having a dual-layer absorbent member, wherein the deposition region of its upper acquisition layer comprises a distribution zone and an acquisition zone having a lower average density and a lower average basis weight per unit area than the distribution zone. The acquisition zone is positioned toward the front of either the absorbent member or the absorbent article so that the acquisition zone may most effectively and efficiently rapidly acquire discharged liquids. The lower storage layer comprises a mixture of hydrophilic fibrous material and discrete particles of absorbent gelling material having a particular size distribution so as to enhance the absorbent capacity and acquisition rate of the dual-layer absorbent member. The upper acquisition layer comprises a homogeneous composition of stiffened, twisted, and curled cellulose fibers which provide enhanced wicking action in the densified distribution zone. The upper acquisition layer serves to rapidly and evenly distribute fluids to the lower storage layer for storage, while freeing the acquisition zone for the next discharge of fluid.
