摘要： A composite absorbent structure and method are disclosed including providing a first wicking layer having preferred liquid transport properties in a preferred contact with a second absorbent retention layer. The composite absorbent structure of the present invention provides preferred liquid transport and liquid retention properties. The composite absorbent structure has a first wicking layer in a preferred contact with the second retention layer by a novel intimate contact means effective to achieve a Contact Intimacy Ratio providing the preferred liquid transport and liquid retention functions when the first wicking layer and the second absorbent retention layer are combined together in accordance with the present invention. In one aspect, a bonding agent is used in the present invention in combination with the first wicking layer of wettable fibers and a second retention layer of a hydrogel-forming polymeric material, preferably superabsorbent, to form a composite absorbent structure having the preferred Contact Intimacy Ratio and providing the preferred liquid transport function and the preferred liquid retention function.

摘要： A method of preparing a nonwoven web that has substantially continuous synthetic fine fiber includes preparing an aqueous amide crosslinked polymer solution. The solution is extruded through a die having a plurality of orifices to form a plurality of threadlines. The threadlines are then attenuated with a primary gaseous source under conditions sufficient to permit the viscosity of each threadline to increase incrementally with increasing distance from the die, at a rate sufficient to provide fibers having a desired attenuation and mean fiber diameter without significant fiber breakage.

摘要： A nonwoven web and method of preparing a novel nonwoven web of synthetic fiber are disclosed. An aqueous solution amide crosslinked synthetic precursor polymer is extruded under defined conditions through a plurality of die orifices to form a plurality of threadlines. The threadlines are attenuated with a defined primary gaseous source to form fiber under conditions of controlled macro scale turbulence and under conditions sufficient to permit the viscosity of each threadline, as it leaves a die orifice and for a distance of no more than about 8 cm, to increase incrementally with increasing distance from the die, while substantially maintaining uniformity of viscosity in the radial direction, at a rate sufficient to provide fiber having the desired attenuation and mean fiber diameter without significant fiber breakage. The attenuated threadlines are dried with a defined secondary gaseous source. The resulting fibers are deposited randomly on a moving foraminous surface to form a substantially uniform web. The moving foraminous surface is positioned about 10 to about 100 cm from the last gaseous source to contact the threadlines. The fibers have a mean fiber diameter in the range of about 0.1 to 30 &mgr;m and are substantially free of shot. The attenuating and drying steps are carried out under conditions of controlled macro scale turbulence.

摘要： An apparatus and process for forming an absorbent web (26) includes an airlaying of a first fibrous stratum (28), and an airlaying of an intermediate fibrous stratum (40) onto the first fibrous stratum. A liquid, wet-strength agent is distributed onto fibers of the intermediate fibrous stratum, and at least a second fibrous stratum (28) is airlaid onto the intermediate fibrous stratum (40). The method is desirably configured to operatively form or join the intermediate fibrous stratum (40) with the first and second fibrous strata, and render the intermediate fibrous stratum (40) substantially non-dispersible in an aqueous liquid. In a particular aspect, the strata of the web (26) can be operatively compressed prior to curing the wet-strength agent. In another aspect, the liquid wet-strength agent can be distributed onto the fibers of the intermediate fibrous stratum (40) during an airlaying of the intermediate fibrous stratum.

摘要： An apparatus and process for forming an absorbent web (26) includes an airlaying of a first fibrous stratum (28) which has a first quantity of absorbent fibers; an airlaying of a second fibrous stratum (34) which has a second quantity of absorbent fibers; and an airlaying of a third, intermediate fibrous stratum (40) which has a third quantity of absorbent fibers. The intermediate fibrous stratum has a location that is interposed between the first fibrous stratum and the second fibrous stratum. A liquid, wet-strength agent is distributed onto the fibers of the intermediate fibrous stratum (40) during the airlaying of the intermediate fibrous stratum to thereby render the intermediate fibrous stratum substantially non-dispersible. The process and apparatus are configured to operatively form or join the intermediate fibrous stratum (40) with at least the first fibrous stratum (28), and in desired aspects, the invention can integrally form or join the intermediate fibrous stratum (40) with both of the first and second fibrous strata (28) and (34), respectively. In a particular aspect, the invention can configure the first and second fibrous strata (28) and (34) to be substantially dispersible in an aqueous liquid, and in a further aspect, the composite strata of the web (26) can be operatively compressed prior to a curing of the wet-strength agent.
