    摘要： There is provided a new nonwoven material for personal care products made of fibers, binder in an amount between 1 and 6 weight percent and superabsorbent in an amount between 1 and 80 weight percent, where the superabsorbent is contained in micro-pockets in the nonwoven. These micro-pockets may be made by creping a nonwoven fabric, orienting fibers in the Z-direction, and by passing a relatively lofty nonwoven fabric between unheated thermal pattern bond and anvil rolls. These materials exhibit good permeability to liquid in the pre- and post-wetted conditions, thus avoiding gel blocking and other negative effects of superabsorbent swelling within a fabric. Such a fibrous material is useful in personal care products, like diapers, training pants, incontinence garments and feminine hygiene products.

    摘要： An absorbent article including a liquid-permeable top layer, an absorbent core layer, a breathable outer cover, and a creped inner nonwoven fibrous layer between the absorbent core and breathable outer cover. The creped inner nonwoven fibrous layer has a level of creping of about 5-75%, and is preferably permanently creped. The creped inner nonwoven fibrous layer serves as a dampness inhibitor which reduces or prevents perceived dampness on the external surface of the outer cover by lowering thermal conductivity between the absorbent core and the outer cover surface.

    摘要： Methods and apparatus for forming a nonwoven fiber web containing a pore size gradient resulting in enhanced wicking properties. A first method utilizes a conventionally formed web having an average pore size and comprises selectively contacting the web with a heat source to shrink the fibers in selected areas. The smaller pore sizes have greater wicking ability. A second method utilizes a novel apparatus and comprises forming a nonwoven fiber web having zones of fibers, each zone having generally an average set of fiber structure and/or composition, the zones preferably overlapping. The zones of fibers are exposed to a heat source, which shrinks the fibers according to their denier and composition. The apparatus uses a conventional meltblown or spunbond system and provides a plurality of resin sources which feed resin to a plurality of meltblowing dies. Each die produces fibers of a particular denier and/or composition which forms zones in a web collected on a collecting belt. The web moves underneath a manifold which blows heated air or sprays boiling water onto the fibers. The fibers shrink according to their structure and composition to form a web having a pore gradient.
