摘要:
The present disclosure is directed, in part, to an absorbent article comprising a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core positioned at least partially intermediate the liquid permeable topsheet and the liquid impermeable backsheet. The liquid permeable topsheet may comprise a flow control material. The flow control material may form an at least mostly enclosed perimeter over at least a portion of the absorbent core. The flow control material may extend outwardly from the liquid permeable topsheet and/or may penetrate a portion of the liquid permeable topsheet.

The present invention relates to a disposable absorbent article (1) comprising a liquid pervious top sheet (2), an absorbent core (4), and a back sheet (3). Said back sheet comprises a fluid permeable polymeric film having uni-directional fluid transfer towards the core, and said core comprising a fluid storage layer, wherein said absorbent article exhibits a fluid contact angle gradient across said storage layer and said back sheet.

A disposable sanitary towel (1) comprising an upper layer which is permeable to liquids (5), a lower impermeable layer (7) and an absorbent member (6) is provided with an intermediate layer (10) located between the upper layer (5) containing the absorbent member (6) and extending around the longitudinal side edges and end edges of the absorbent member (6) so as to distribute the liquid received and to prevent the loss of liquid from the edges of the absorbent member (6).
摘要:
The present invention relates to a simple, cost-effective, stretchable, superabsorbent material-containing absorbent structure that provides the superabsorbent material particles therein with improved liquid holding capacity. The stretchable absorbent structure can be used in absorbent articles such as diapers, sanitary napkins, panty liners, and incontinence pads. The stretchable absorbent structure comprises a stretchable liquid impervious barrier layer (40) and an absorbent nonwoven component (43) that is bonded to the barrier layer when the barrier layer is stretched at least partially toward its stretched condition, and superabsorbent, hydrogel-forming material (41) deposited on or distributed within the nonwoven component.
摘要:
A new controlled release vehicle which acts by breakdown of the entrapping material upon hydration has been developed. The preferred release vehicle is made of a carboxylated cellulose, e.g., carboxymethylcellulose, which is treated with a cross-linking agent such as aluminum ions and, preferably, a hydrophobicity agent such as acetic acid. The vehicle is broken down by a release agent, e.g., cellulase, which may be coated on the vehicle together with a coating agent, e.g., hydroxypropylcellulose. The vehicle is dried, entrapping the molecule to be entrapped, e.g., an enzyme, and hydration activates the cellulase which breaks down the carboxymethylcellulose, releasing the entrapped molecule.
摘要:
The present invention relates to a personal care absorbent article comprising at least two substrates each having an internal and external surface, wherein at least one substrate is a fluid permeable bodyside substrate selected from spunbond, meltblown, coform, airlaid, bonded-carded web, spunlace materials and combinations thereof; at least one substrate is an impermeable backsheet; and an absorbent core disposed in between said substrates; wherein at least the external surface of at least one substrate has applied to it a benefit agent selected from an additive composition wherein said additive composition is a polymer dispersion selected from polyolefin dispersions, polyisoprene dispersions, polybutadiene-styrene block copolymer dispersions, latex dispersions, polyvinyl pyrrolidone-styrene copolymer dispersions, polyvinyl alcohol-ethylene copolymer dispersions, and combinations thereof; an enhancement component selected from microparticles, expandable microspheres, fibers, additional polymer dispersions, scents, anti-bacterials, moisturizers, medicaments, soothers and combinations thereof; and combinations thereof.
摘要:
The present invention relates to absorbent articles such as sanitary napkins, panty liners, and incontinence pads. More particularly, the present invention relates to absorbent articles, such as sanitary napkins, that have longitudinal side edge components (52) that naturally wrap the sides (22) of a wearer's panties which provide an alternative to conventional side flaps. The side edge components are extensible, and may be attached inboard of the longitudinal edges of the main body of the article, or be decoupled from the main body, or comprise part of the impervious backsheet of the main body.
摘要:
Sanitary article of the type comprising an external backing sheet which is impervious to liquids, an absorbing pad (6), an internal cover sheet (5) pervious to liquids and two side flaps (15) with elastic elements. An additional sheet (25) is arranged under the cover sheet (5) overlapping one transverse edge (10) of the cushion or pad, and is connected on all its contour by gluing to the cover sheet which presents, over the additional sheet (25), a tranverse cutting (23) and an elastic element (24) passing along the edge of the cutting in order to form a waist sealing pocket open at the cutting (23). Application: particularly to pilches.
摘要:
A new gel-like composition of matter containing a complex carbohydrate with a high degree of carboxyl substitution cross-linked by an organic cross-linker has been developed. The cross-linkers have complex ring structures, e.g., polynuclear or heterocyclic compounds, which permit development of two distinct partial positive charges under conditions where a carbohydrate is negatively charged. Antibiotics are the preferred cross-linking agents and a method of sustained release of the antibodies is also disclosed.
