摘要： A method for hydroforming a spun bonded nonwoven web includes applying a plurality of pressurized liquid jets onto an original unexpanded spun bonded nonwoven web having an original loft while the web passes over a forming structure. A plurality of spun bonded fibers in the original unexpanded spun bonded nonwoven web are reoriented from a closely packed substantially horizontal orientation to a more loosely packed orientation with greater vertical spacing between the fibers to produce a hydroformed expanded spun bonded nonwoven web having a loft of at least about 1.3 times greater than the original loft of the original unexpanded spun bonded nonwoven web, and an air permeability of at least about 1.2 times greater than an original air permeability of the original unexpanded spun bonded nonwoven web. The hydroformed expanded spun bonded nonwoven web has a surface with a plurality of protuberances in a pattern corresponding to the pattern of apertures in the forming structure.

摘要： A fluid distribution material for use in an absorbent article includes a formed film layer having first and second sides and a basis weight of between about 10 gsm and about 25 gsm, and a nonwoven layer having a basis weight of between about 10 gsm and about 15 gsm and laminated to the formed film layer. The formed film layer includes a plurality of apertured protuberances arranged in a pattern having 10 to 40 protuberances per linear inch. Each of the protuberances includes a continuous sidewall extending from the first side, and the second side has a plurality of apertures aligned with the plurality of protuberances, and land areas in between the apertures. The nonwoven layer includes a plurality of fibers attached to the formed film layer at the land areas. The material has a rewet value of less than 0.075 grams in accordance with the Rewet Test Method.

摘要： An illustrative aspect of the invention provides a film comprising a release layer defining a first outer film surface and an adhesion layer defining a second outer film surface opposite the first outer film surface. The adhesion layer comprises a hydrogenated styrene block copolymer with a styrene content in a range of about 30% to 40% by weight. In some embodiments, the adhesion layer may further comprise low density polyethylene (LDPE). In some embodiments, the adhesion layer may further comprise LDPE and high density polyethylene (HDPE).
