  • Publication number: 20030119394
    Abstract: A nonwoven composite web contains coated superabsorbent and binder, such as thermoplastic staple fibers. The nonwoven composite web is easily made, economical, and has good distribution of materials, high absorbent particle loading, saturation capacity and flexibility.

  • Publication number: 20030116890
    Abstract: A nonwoven web contains an even distribution of its composite materials by the separate application of particulate material such as superabsorbent particles into a forming head outside the air stream for deposition of thermoplastic fibers in the forming head. The thermoplastic fibers are distributed by air entertainment through tubular forming screens having rotary distribution members therein. The particulate absorbents are generally placed in the forming box by distribution units which may have metering devices and outlet chutes extending into the forming head.

  • Publication number: 20030118780
    Abstract: An in-line formed, non-laminated web is suitable for use as a composite fluid distribution and fluid retention layer in a disposable absorbent article. The web can be formed by selective deposition of airlaid materials including absorbents, such as pulp and superabsorbents, together with binder fibers. The web so constructed will have a plurality of intermingled lower basis weight areas and higher basis weight areas coexisting and distributed in at least a central region of the web, the alternations crossing the X axis or Y axis, or both, of the web, with the higher basis weight areas being a greater thickness in the Z-direction than the lower basis weight areas. The web so constructed will further have no discrete material boundaries between the lower basis weight stripes and the higher basis weight stripes. Further the necessity of later processing on the web to achieve a ridged structure is removed and the fibers will remain whole and undisturbed.

  • Publication number: 20030118764
    Abstract: An in-line formed web having major surfaces in the X-Y plane and a depth in the Z direction is suitable for use as a composite fluid distribution and fluid retention layer in a disposable absorbent article. The web contains multiple layers of composite material which may have both thermoplastic fibers and absorbent material. The multiple layers can have different compositions of thermoplastic fibers and absorbent material as applied in-line by various arrangements of thermoplastic melt dies and absorbent fiber dispensers. By arranging at least two of the multiple layers in an opposing relation overlaid in the Z-axis direction of the web, a gradient can be formed in the Z-direction of the web. By coordinating the timing and deposition of the material onto a forming wire, at least one of the multiple layers is arranged to have zones of intermittent material deposition in at least one of a machine direction or a cross direction of the web.
