TAMPON WITH WICKING MEMBER ADAPTED FOR IMPROVED MANUFACTURABILITY AND WICKING PERFORMANCE
The disclosed tampon may include a pledget having a rearward end; a wicking member having a trailing portion trailing the rearward end and having a rearward edge; and a withdrawal cord with an attached portion attached to the pledget and a free portion trailing the rearward edge. In an opened condition the pledget has a pair of side edges and a pledget width, and includes fibrous absorbent material and an outer cover of a first section of nonwoven web at least partially covering the absorbent material, the trailing portion of the wicking member including at least four layers of nonwoven web, at least one of which is an extension of the first section of nonwoven web. The wicking member may have a width substantially equal to the pledget width; and the trailing portion may have a length of at least about 10 mm and no greater than about 60 mm.
ABSORBENT CORE WITH PROFILED DISTRIBUTION OF ABSORBENT MATERIAL
An absorbent core for absorbent articles such as diapers comprising a core wrap comprising a top side and a bottom side, an absorbent material between the top side and the bottom side of the core wrap, a first and second longitudinally-extending channel-forming areas disposed on opposite sides of the longitudinal axis and substantially free of absorbent material preferably through which the top side of the core wrap is preferably attached to the bottom side of the core wrap. The core has a central absorbent zone between the first and the second channel-forming areas and a first and second lateral absorbent zones disposed laterally outwardly. The basis weight of the absorbent material in the central absorbent zone is higher than the basis weight of the absorbent material in each of the lateral absorbent zones for at least a first transversal section (S1). This relation is inverted along a second transversal section (S2) of the core. The first and second sections have each a length in the longitudinal direction of at least 10 mm.
Fluid-Absorbent Article
A fluid-absorbent article having an upper liquid-pervious layer, a lower liquid-impervious layer, a fluid-absorbent core between the layer and the layer, containing from 0 to 20% by weight fibrous material and from 80 to 100% by weight of a water-absorbent polymer material, based on the sum of water-absorbent polymer material and fibrous material. The fluid absorbent article has a first intake time of 15 seconds or less by the hanging U-shape test (HUS).
DISPOSABLE ABSORBENT ARTICLE COMPRISING A CORE WITH MULTIPLE LAMINATES
Disposable absorbent articles suitable for providing leakage protection for users that experience relatively small to relatively large discharges of fluids are described. The article includes a primary topsheet, a backsheet, and an absorbent system disposed between the topsheet and the backsheet. The absorbent system includes a first absorbent core and a second absorbent core, and wherein the primary topsheet and at least the first absorbent core include a plurality of recessed areas.
Polymeric material
A polymeric material that includes a thermoplastic composition containing a continuous phase that includes a matrix polymer and a siloxane component is provided. The siloxane component contains an ultrahigh molecular weight siloxane polymer that is dispersed within the continuous phase in the form of discrete domains. A porous network is defined within the thermoplastic composition that includes a plurality of nanopores.
Fluid management layer for an absorbent article
A fluid management layer having a basis weight of between about 40 grams per square meter (gsm) and about 120 gsm is described. The fluid management layer has a plurality of absorbent fibers, a plurality of stiffening fibers and a plurality of resilient fibers, wherein the absorbent fibers are present at about 20 percent to about 75 percent by weight, and wherein the integrated, carded, staple fiber, nonwoven has a first side and a second side, and wherein there is a higher number of absorbent fibers on the first side or second side versus the other.
Layered product comprising superabsorbent polymer
A layered product including at least one natural fiber layer including a web of natural fibers and at least one SAP layer including a non-woven substrate including a thermoplastic polymer fibers and a superabsorbent polymer adhered to thermoplastic polymer fibers, wherein the non-woven substrate is a high loft fabric, for example an airlaid or spunlaid non-woven, and wherein the natural fiber layer and the SAP layer are connected to each other by needle punching, stitch bonding or using an adhesive. A process to prepare the layered product and the use of the layered product in for example horticulture.
Disposable absorbent article with unitary topsheet and unitary absorbent article
The present invention relates to disposable absorbent articles such as sanitary napkins, panty liners, baby diapers, adult incontinence articles and sweat pads. According to the present invention the absorbent article in the region designated for liquid deposition on its wearer facing surface has a single layer topsheet onto which liquid to be absorbed is provided during use of the article. The absorbent article includes a backsheet forming the liquid barrier surface and a unitary absorbent core between the topsheet and the backsheet. Importantly the unitary core provides improved liquid handling to the absorbent article and increases the masking, i.e. ability to hide stains due to absorbed liquid, of the article. This is particularly beneficial in the context of articles for absorption of liquids with high color intensity, such as menstrual liquid or urine of older adults.
Resilient absorbent products with enhanced resistance to tearing
The present disclosure provides a sanitary napkin that is thin, highly absorbent and has resiliency properties that are selected to provide good comfort potential and at the same time reduce the likelihood of deformation and breaking. In a specific example, the sanitary napkin comprises a cover layer, an absorbent system and a barrier layer. The absorbent system includes an absorbent core and a reinforcement layer.
FLUID MANAGEMENT LAYER FOR AN ABSORBENT ARTICLE
A fluid management layer having a basis weight of between about 40 grams per square meter (gsm) and about 120 gsm is described. The fluid management layer has a plurality of absorbent fibers, a plurality of stiffening fibers and a plurality of resilient fibers, wherein the absorbent fibers are present at about 20 percent to about 75 percent by weight, and wherein the integrated, carded, staple fiber, nonwoven has a first side and a second side, and wherein there is a higher number of absorbent fibers on the first side or second side versus the other.
