Abstract:

A distinctive absorbent article includes an absorbent core having multiple absorbent layers, wherein the absorbent layers interact in such a manner which preferentially locates absorbed liquid in an appointed, high saturation wicking layer. The localization of the liquid within this wicking layer increases the potential of this layer to move liquid through capillary action due to the higher saturation level and increased amount of liquid available. The intake capability of the absorbent system is maintained or improved over current systems by keeping a second layer of the absorbent system at low saturation levels through as many insults of the product as possible, while providing optimum intake performance through appropriate control of the composite properties. The low saturation in this layer provides void volume for the incoming insult as well, as a high permeability, thus increasing the intake rate of the absorbent system as a whole, but the structure of the low saturation layer is also balanced to provide an appropriately high level of capillary tension to provide enough control of the liquid to stop leakage from occurring. This low saturation layer is used in addition to a surge material and provides intake functionality in addition to that provided by the surge material.

Abstract:

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.

International Classification:

B27N 304

US Classification:

264113, 425 811

Abstract:

An apparatus and process for forming an absorbent web ( ) includes an airlaying of a first fibrous stratum ( ) which has a first quantity of absorbent fibers; an airlaying of a second fibrous stratum ( ) which has a second quantity of absorbent fibers; and an airlaying of a third, intermediate fibrous stratum ( ) 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 ( ) 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 ( ) with at least the first fibrous stratum ( ), and in desired aspects, the invention can integrally form or join the intermediate fibrous stratum ( ) with both of the first and second fibrous strata ( ) and ( ), respectively. In a particular aspect, the invention can configure the first and second fibrous strata ( ) and ( ) to be substantially dispersible in an aqueous liquid, and in a further aspect, the composite strata of the web ( ) can be operatively compressed prior to a curing of the wet-strength agent.

Abstract:

Disclosed is a fibrous absorbent structure that is wet stable and has large void volume with a density below the critical density of the fiber employed. In one embodiment, the fibrous absorbent uses open-celled foam technologies to keep the fibrous structure expanded and bonded. In other embodiments, the resulting fibrous structure resembles an open-celled polymeric foam, with fibers serving as struts stabilized by binder material. In another embodiment, the resulting fibrous structure is filled with hydrophilic open-celled foams with the cell size substantially smaller than the fibrous pores. Such a wet-stable, high void volume fibrous absorbent can be used in a disposable product intended for the absorption of fluid such as body fluid, including extensible absorbent articles.
