PROCESS FOR FORMING COMPOSITE ABSORBENT MATERIAL AND COMPOSITE ABSORBENT MATERIAL MADE BY THE PROCESS
A process for forming a composite absorbent structure by advancing a nonwoven web including from 20% to 100% by weight of superabsorbent fibers. Superabsorbent particles may be distributed to the nonwoven web and at least some of the superabsorbent particles may be drawn into void spaces of the nonwoven web to form the composite absorbent structure. The composite absorbent structure may include a nonwoven web comprising from 20% to 100% by weight of superabsorbent fibers, and the superabsorbent particles may be distributed heterogeneously into void spaces within the nonwoven web. The composite absorbent structure may be used in an absorbent article.
ABSORBENT ARTICLES HAVING APERTURED, THREE-DIMENSIONAL MATERIALS AND METHODS FOR MAKING SAME
A forming apparatus for forming a plurality of apertures in a nonwoven substrate is provided. The apparatus includes intermeshing members having a first and second member. The first member includes a body portion and a plurality of conical-shaped pins. The plurality of conical-shaped pins each have a first section having a first wall extending from a base portion to a distal portion, at least a portion of the first wall disposed at a first angle greater than 17.5 degrees relative to a central axis. The plurality of conical-shaped pins each have a second section having a second wall extending from a base portion, the base portion extending from the first member body portion, at least a portion of the second wall disposed at a second angle relative to the central axis of each conical-shaped pin, the second angle being different than the first angle and less than 20 degrees.
Absorbent Articles
Absorbent articles comprising material webs are disclosed herein. The material webs described herein can provide a bevy of benefits when utilized in the context of absorbent articles, and such material webs can facilitate the manufacturing of absorbent article.
MATERIALS AND METHODS OF MANUFACTURING RELATED TO APPARATUS FOR COLLECTING URINE
The present disclosure provides improvements related to the following: (1) various materials for use in the external permeable wicking cover (outer bandage covering); (2) the placement of a shape retention element within an edge seam of the core wherein the shape retention element has rolled ends to prevent any sharp ends; and (3) various production improvements related to heat blooming of core for shape retention, continuous processing of the external covering and core, automatic cutting to length during production, vacuum hold for insertion of the core into the outer impermeable housing, and heat mold gluing/forming of the outer covering to the inner core.
WOUND DRESSING AND METHOD OF TREATMENT
Embodiments disclosed herein are directed to negative pressure treatment systems and wound dressing systems, apparatuses, and methods that may be used for the treatment of wounds. In particular, some embodiments are directed to improved wound dressings comprising an obscuring layer that may hide fluid contained therein. Some embodiments may further comprise one or more viewing windows disposed therethrough so as to enable monitoring or examination of fluids contained therein.
Fluid distribution material for absorbent articles
A fluid distribution material for use in an absorbent article includes a formed film layer having a user-facing side and a garment-facing side opposite the user-facing side. The formed film layer includes a plurality of apertured protuberances arranged in a pattern having 10 to 40 protuberances per linear inch. Each of the protuberances includes a continuous sidewall extending from the user-facing side. The garment-facing side has a plurality of apertures aligned with the plurality of apertured protuberances and land areas in between the apertures. A nonwoven layer is laminated to the garment-facing side of the formed film layer. The nonwoven layer includes a plurality of continuous fibers extending across the land areas and the plurality of apertures of the formed film layer and attached to the land areas at bond sites. The fluid distribution material has a compressibility of less than 10% between pressures of 0.21 psi and 0.60 psi.
Absorbent article with leg cuffs
A disposable absorbent article may include a chassis that includes a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet; and a leg gasketing system. The leg gasketing system may include an inner cuff and an outer cuff; the inner cuff may include an inner cuff folded edge and an inner cuff material edge and the outer cuff may include an outer cuff folded edge and an outer cuff material edge such that the web of material is folded laterally inward to form the outer cuff folded edge and folded laterally outward to form the inner cuff folded edge. The leg gasketing system may also include a leg gasketing system pocket with an opening on an inboard longitudinal edge of the pocket.
ABSORBENT ARTICLES HAVING APERTURED, THREE-DIMENSIONAL MATERIALS AND METHODS FOR MAKING SAME
An absorbent article is provided. The absorbent article includes a nonwoven, liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core disposed at least partially intermediate the topsheet and the backsheet. The absorbent article includes an apertured substrate having a layer of fibers and has a plurality of apertures defined in the layer of fibers. At least some of the apertures have a side wall having a portion disposed an angle in the range of about 55 degrees to about 90 degrees, according to the 2D X-Ray CT Scan Test herein.
Absorbent articles having apertured, three-dimensional materials and methods for making same
An absorbent article is provided. The absorbent article includes a nonwoven, liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core disposed at least partially intermediate the topsheet and the backsheet. The topsheet includes a layer of fibers and has a plurality of apertures defined in the layer of fibers. At least some of the apertures have a side wall having a portion disposed an angle in the range of about 55 degrees to about 90 degrees, in the range of about 60 degrees to about 80 degrees, or in the range of about 63 degrees to about 75 degrees, according to the 2D X-Ray CT Scan Test herein.
TUNABLE ABSORBENT UNDERGARMENT
An absorbent undergarment with a tunable absorbent portion. The tunable portion being tunable to absorb and/or capture both fluid materials as well as more viscous, solid, and/or semi-solid materials. Thus, the undergarment affords the user improved wearability as well as comfort and avoids unwanted odors from exposed material.
