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.

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.

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.

Abstract: A versatile sorbent material is provided comprising a fibrous sheet having applied thereto a wetting chemistry comprising (i) a poly glycoside; (ii) a fatty acid ester ethoxylate; and (iii) one or more surfactants selected from the group consisting of alkyl and aryl alcohol ethoxylates, alkyl sulfonates and sulfates, alcohol ether sulfates, alkyl phosphates and phosphonates, alkyl sulfosuccinates and sulfated fatty acid esters. A sorbent material is provided having excellent electrical resistivity and good absorption properties for a broad range of liquids including paraffin oil, water, sulfuric acid and sodium hydroxide.

Abstract: There is provided an abrasion resistant, oil absorbing fabric comprising at least one layer of fine microfibers having an average diameter of at least 10 samples of between about 1 and 7 microns bonded with at least one layer of coarse microfibers having an average diameter of at least 10 samples of between about 8 and 23 microns wherein said fabric has a basis weight between about 190 and 407 gsm and has not been secondarily bonded, except, if desired, the fabric may be pin bonded. Such a fabric has been found to be well suited to use as an oil absorbent floor mat. It has further been found that such a fabric has sufficient integrity to withstand wringing out in order to reclaim absorbed fluids.
