NONWOVEN FABRIC STRUCTURE FOR ABSORBENT ARTICLES AND ABSORBENT ARTICLE COMPRISING SUCH A NONWOVEN FABRIC STRUCTURE
A nonwoven fabric structure for absorbent articles comprising a first layer, a second layer and superabsorbent particles, said first layer comprising endless filaments, —which comprise at least a first polymeric material (A) and a second polymeric material (B) having its melting point lower than the first polymeric material (A), —wherein the second polymeric material (B) extends in the longitudinal direction of the filament and forms at least a part of the surface of the filament and—the first layer contains filament-to-filament bonds formed of the second polymeric material (B), —void volume between the filaments of the first layer forms at least 65% of the volume of the first layer, the second layer comprising endless filaments, wherein the superabsorbent particles are arranged at least between the first layer and the second layer and within some of the voids of the first layer and/or the second layer.
ABSORBENT NONWOVEN MATERIALS
The presently disclosed subject matter relates to multi-layer nonwoven materials and their use in absorbent articles, e.g., as absorbent cores and/or acquisition distribution layers (ADL). More particularly, the presently disclosed subject matter relates to layered structures that provide for improved liquid acquisition, distribution, storage and rewet properties while allowing for the use of less synthetic materials, such as superabsorbent polymers (SAP) than other commercially available materials.
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.
Folded disposable absorbent articles
Disposable absorbent articles are disclosed herein having a first and second fold line. The disposable absorbent articles have a topsheet, a backsheet, and an absorbent system disposed therebetween. The absorbent system has a first absorbent core and a second absorbent core which may be configured in an offset manner. And, the absorbent system and/or the first and second fold lines may be configured with respect to the absorbent article to effect a caliper change in the folded article.
AIRLAID NONWOVEN
Provided is a composite sheet material having a first layer and an airlaid nonwoven layer overlying the first layer wherein the airlaid nonwoven layer includes a blend of bamboo derived staple fibers and non-cellulose staple fibers, and in which the airlaid nonwoven layer includes a first surface disposed towards, and thermally bonded, to a surface of the first layer, and a second surface defining an outer surface of the composite sheet material.
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.
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.
MULTI-LAYERED ABSORBENT ARTICLE
An absorbent article for menstrual and/or incontinence purposes, having a unique two-layer acquisition and absorbent structure. The cover layer includes a nonwoven material. The absorbent core includes multiple strata including super absorbent, fiber material that is pulp and/or bicomponent fibers, and a binder material. The total thickness of the absorbent article is less than or equal to the thickness of absorbent articles of similar absorbent characteristics. The absorbent article includes various absorbent properties that are improved despite parity or reduction in overall thickness.
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.
ABSORBENT LAYERS SUITABLE FOR USE IN ABSORBENT ARTICLES AND METHODS FOR MAKING SAME
Provided are absorbent layers and articles, and methods for making absorbent layers and articles. The absorbent layer is suitable for use in an absorbent article and may include a nonwoven that includes bicomponent fibers and superabsorbent polymer material interconnected within the nonwoven. The absorbent layer according to different embodiment may include a three-dimensional random loop material with superabsorbent polymer material adhered to the three-dimensional random loop material. Absorbent articles may comprise the absorbent layer according to embodiments of the present disclosure. The method for making the absorbent layer includes providing a nonwoven and dosing the nonwoven with superabsorbent polymer material.
