    摘要： A method of forming thiolated poly(vinyl alcohol) hydrogels including reacting, in the presence of an acid, compounds containing a thiol functional group and a hydroxyl reactive group with one or more hydroxyl groups of poly(vinyl alcohol) via said hydroxyl reactive group, thereby forming thiolated poly(vinyl alcohol). The method further including reacting the thiol functional group of said compounds with a thiol reactive group of a crosslinker, thereby forming a hydrogel.

    摘要： Apparatus (100, 101, 102) and die cartridge assembly (18, 44, 45, 47) adapted for use with same for producing fibrous material (212). The apparatus (100) comprises a removably attachable die cartridge assembly (18) that adapts to conventional spunmelt equipment. The die cartridge assembly (18) is removably positionable beneath an extrusion body (10) for effecting formation of fibrous material by fibrillation of polymer films. The cartridge assembly (18) includes at least one polymer passage (19) communicating with a molten polymer source (10) for directing molten polymer onto at least one film forming surface (20, 28) defined by the cartridge assembly (18), and also defines at least one gas passage (222, 22, 30) communicating with a gas source (16) for directing pressurized gas (220) against the molten polymer (210) in the form of a film for effecting formation of the fibrous material (212).

    摘要： A liquid management layer constructed from large diameter uncrimped fibers in the form of a spunbond nonwoven web is described. Embodiments of the liquid management layer can include a plurality of thermoplastic fibers in the form of a spunbond nonwoven web where the plurality of thermoplastic fibers are randomly oriented and uncrimped, where the liquid management layer has a maximum void volume of 25 cc/g and a web density of at least 0.05 g/cc, where the liquid management layer has a maximum thickness of 1.5 mm, a basis weight of at least 30 g/m2 and a rewet value of less than 0.4 g according to test method WSP 70.8, and where the liquid management layer has an average fiber diameter of at least 40 microns based on the number of thermoplastic fibers in the liquid management layer and where less than 10% by count of the plurality of thermoplastic fibers in the liquid management layer have an absolute fiber diameter less than 30 microns. Additional embodiments of the invention include a personal care absorbent article incorporating the liquid management layer over an absorbent core.
