Disclosed is a composite web including a base web, a first web of fastener material, a first sinusoidal line of separation and a second sinusoidal line of separation. In one aspect, the composite web can be used to form components for absorbent articles.

Composite web

Absorbent, elastomeric materials and methods of making absorbent, elastomeric materials. The absorbent, elastomeric materials include an elastomeric substrate and a superabsorbent polymer non-adhesively attached to the substrate. The elastomeric substrate includes at least one nonwoven, and may include, for example, elastic strands, elastic film, and/or elastic foam between layers of nonwoven. The superabsorbent polymer includes particles that either encase fibers of the nonwoven or bond themselves to fibers of the nonwoven.

Elastomeric nonwoven with attached superabsorbent polymer

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.

Process of making a nonwoven web

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.

Synthetic fiber nonwoven web and method

A dynamic-fitting absorbent article that includes a liquid impermeable outer cover ( ), a liquid permeable bodyside liner ( ) in superimposed relation to the outer cover ( ) and a continuous elastic absorbent core ( ) disposed between the outer cover ( ) and the bodyside liner ( ). The continuous elastic absorbent core ( ) can extend from about 80 to about 400 percent upon application of a force of from about 60 to about 325 grams. The continuous elastic absorbent core ( ) can have a tension reducing geometry in the crotch section of the article. Additionally, the continuous elastic absorbent core can have a dry tensile strength and a wet tensile strength that is at least 95% of the dry tensile strength.

Continuous biaxially stretchable absorbent with low tension

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 Am and are substantially free of shot. The attenuating and drying steps are carried out under conditions of controlled macro scale turbulence.

An absorbent article ( ) includes a backsheet layer ( ), a liquid permeable topsheet layer ( ), and an absorbent body ( ) sandwiched between the backsheet and topsheet layers. The absorbent body ( ) includes a first fibrous stratum ( ) having a first quantity of absorbent fibers, a second fibrous stratum ( ) having a second quantity of absorbent fibers, and at least a third fibrous stratum ( ) which is located between and integrally formed with the first and second fibrous strata ( ). In particular aspects, the third fibrous stratum ( ) includes an operative quantity of a substantially hydrophilic, wet-strength agent. In other aspects, the wet-strength agent is distributed in the third quantity of absorbent fibers to render the third fibrous stratum ( ) substantially non-dispersible.
