Absorbent layer for an absorbent article
A fluid management layer having an integrated, carded, nonwoven is described. The fluid management layer has a basis weight of between about 115 grams per square meter (gsm) and about 200 gsm; a plurality of absorbent fibers; a plurality of stiffening fibers; and a plurality of resilient fibers. The absorbent fibers make up from about 20 percent to about 60 percent by weight of the fluid management layer. The stiffening fibers have a dtex of between 4 and 10, and the resilient fibers have a dtex of between 3 and 12.
ABSORBENT BODY FOR BODY FLUID-ABSORBING ARTICLES
Provided is an absorbent body for body fluid-absorbing articles, that is both soft and strong. The absorbent body for body fluid-absorbing articles: includes 100 parts by mass cellulose-based water-absorbent fibers and 7.5-100 parts by mass thermoplastic resin fibers; and has an apparent density of 0.06-0.14 g/cm.sup.3. The thermoplastic resin fibers having a fiber length longer than the cellulose-based water-absorbent fibers are twisted together. The absorbent body has compressed sections arranged in a repeated pattern. The compressed sections are characterized by having a Gurley bending resistance of no more than 1 mN as a result of not being fused.
Absorbent article having acquisition layer
An absorbent article includes a liquid permeable top sheet, a liquid impermeable back sheet, an absorbent core being arranged between the top sheet and the back sheet, and an acquisition and distribution layer (ADL) of a nonwoven material being arranged between the top sheet and the absorbent core. The nonwoven material has a basis weight of 20-40 g/m.sup.2, 3-20 through holes per cm.sup.2, the holes having a diameter in CD and MD of 1-3 mm, and at least 70% by weight of the nonwoven ADL includes fibers having a fiber diameter of 12-22 m.
ABSORBENT STRUCTURE
An absorbent structure comprising a single stratum exhibiting a Capillarity Work Potential greater than the Capillarity Work Potential trade-off Boundary.
ABSORBENT ARTICLE CONTAINING NON-WOVEN FABRIC SHEET FOR ABSORBENT, AND METHOD FOR PRODUCING NON-WOVEN FABRIC SHEET FOR USE IN SAID ABSORBENT ARTICLE
An absorbent article contains a non-woven fabric sheet for an absorbent. The non-woven fabric sheet is produced without employing a strength-imparting means such as post-coating of an adhesive agent that can deteriorate a liquid diffusion property of the non-woven fabric sheet. The absorbent article includes a liquid-permeable surface sheet, a liquid-impermeable back sheet, an absorbent arranged therebetween, and the non-woven fabric sheet for the absorbent. The non-woven fabric sheet contains pulp, a pulp fiber layer, a first-surface-side fiber layer arranged on a first surface of the pulp fiber layer and mainly composed of hydrophilic fibers having an average fiber length of 25 to 64 mm, and a second-surface-side fiber layer arranged on a second surface of the pulp fiber layer and mainly composed of hydrophilic fibers having an average fiber length of 25 to 64 mm.
ABSORBENT ARTICLE HAVING IMPROVED COMFORT
An absorbent article includes a liquid pervious topsheet, a backsheet at least peripherally joined to the topsheet, and an absorbent core disposed between said topsheet and said backsheet. The absorbent article further includes an integrated nonwoven fluid management layer having a basis weight between about 40 gsm and about 65 gsm; and an Urine Standard Rewet Value of 10 mg or less.
ABSORBENT ARTICLE HAVING NONWOVEN LATERAL ZONES
An absorbent article for collecting bodily fluid having a topsheet, a backsheet and an absorbent structure. The article may include a central fluid acquisition zone, a first lateral zone situated on one side of the central zone and a second lateral zone situated on the opposite side of the central zone, wherein the first and second lateral zones are formed by a nonwoven material.
Absorbent article with conforming features
A disposable absorbent article is described herein. The disposable absorbent article includes a topsheet, a backsheet, and an absorbent system disposed between the topsheet and the backsheet. At least a portion of the has a plurality of conforming features such that the absorbent article has a blot residual value of less than 30 mg and a bending stiffness of less than 12.
FLUID MANAGEMENT LAYER FOR AN ABSORBENT ARTICLE
A fluid management layer that includes a nonwoven having a basis weight of from about 40 gsm to about 75 gsm, from about 15 to about 35 weight percent of cellulosic fibers, from about 65 to about 85 weight percent of bonding fibers, wherein the fluid management layer has a caliper factor of from about 0.26 to about 0.35, and wherein the cellulosic fibers and the bonding fibers have a decitex below about 2. The fluid management layer can be included in a disposable absorbent article.
Absorbent article with conforming features
A disposable absorbent article has a topsheet; a backsheet; an absorbent core disposed between the topsheet and the backsheet; and a first plurality of conforming features in at least the absorbent core or a combination of the absorbent core and the topsheet. At least a portion of the are depressions, wherein the depressions have a depression centerline bisecting a length and/or width of the depression. A first strut forms a first sidewall of the depression opposite a second sidewall of the depression formed by a second strut, wherein neither of the first strut nor the second strut extend longitudinally and/or laterally beyond the depression centerline by more than 0.75 mm.
