ABSORBENT CORE COMPRISING A HIGH LOFT CENTRAL LAYER AND TWO DIFFERENT SUPERABSORBENT POLYMERS
An absorbent core for use in an absorbent article including a high loft central layer having deposited on two different surfaces thereon a first superabsorbent polymer SAP1 and a second superabsorbent polymer SAP2 in the form of particles that are at least partially distributed within the high loft layer. The SAP1 has a higher capacity than SAP2 and the permeability of SAP2 is more than 5×10-7 cm3.Math.s/g.
Method of making an absorbent composite and absorbent articles employing the same
Disclosed is an absorbent core composite for a disposable absorbent article. The absorbent composite has a first fabric, a body side second fabric, and a plurality of aggregates of superabsorbent particles (SAP) situated between the first fabric second fabric. About each of a plurality of the SAP aggregates, an arrangement of spaced apart bond sites secure the second fabric to the first fabric and form a pocket in which the SAP aggregate is secured between the first fabric and the second fabric. The body side second fabric is a bulky nonwoven including fibers that entangle at least some particles in the SAP aggregate.
Indirect printing of AGM
The present invention relates to a method of applying absorbent gelling material (AGM) granules by indirect printing onto an carrier layer for use in an absorbent article, particularly diaper for babies or adults, training pants, pull-up diapers (diaper pants), sanitary napkins, panty liners or the like. These articles typically comprise the carrier layer with the AGM particles together with further layers, making up the complete article.
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).
FLUID-ABSORBENT ARTICLE
Absorbent core and an absorbent article respectively with improved properties, especially rewet performance, are disclosed. The absorbent core contains at least two layers, wherein each layer has from 0 to 10% by weight fibrous material and from 90 to 100% by weight water-absorbent polymer particles, based on the sum of water-absorbent polymer particles and fibrous material. The surface crosslinked water absorbent polymer particles within the upper layer have a sphericity of at least 0.89 and the absorbent core shows a CRC.sub.AP/TAC.sub.AP ratio of at least 0.65.
ULTRATHIN FLUID-ABSORBENT ARTICLE
An absorbent core and an absorbent article respectively with improved properties, especially rewet performance, are disclosed. The absorbent core has at least two layers, wherein each layer comprising from 0 to 10% by weight fibrous material and from 90 to 100% by weight water-absorbent polymer particles, based on the sum of water-absorbent polymer particles and fibrous material. The surface-postcrosslinked water absorbent polymer particles within the upper layer have a sphericity of at least 0.89 and a CRC of at least 34 g/g. Preferably the water-absorbent polymer particles have a sphericity of at least 0.89 and the sum of the CRC and AUL (0.3 psi, 21 g cm.sup.−2) (EDANA 442.2-02) of the water absorbent polymer particles is at least 65 g/g.
UNDERPANTS-TYPE DISPOSABLE DIAPER
The present invention is intended to improve the dynamic fit of a crotch portion. The foregoing issue is solved in such a manner that a vertical stretchable part vertically extending and contracting in length is provided in a vertical intermediate portion of an absorber in a front body, an outer body of the front body has a portion overlapping at least the vertical stretchable part, width-direction both side sections of the portion, and a waist opening-side area of the portion and the sections, lifting elastic members having a contraction force of lifting a portion of the vertical stretchable part on a rear side of a front end toward width-direction both sides and an obliquely upward side at least when the diaper is worn are provided in the outer body of the front body on closer to lateral sides than to a width-direction intermediate portion of the absorber, and the vertical stretchable part vertically extends and contracts in length by elastic extension and contraction of the lifting elastic member.
ABSORBENT ARTICLE
An absorbent article includes a concave groove whose transverse plane shape satisfies (1) a relationship between a depth “h” of a bottom surface portion of the concave groove, and a distance “S” from a bottom end “G” of the concave groove to an upper end “K” from which a concavity of the concave groove starts is 1.5h<S, (2) a relationship between a width “b” of a bottom surface of the concave groove, and a width “B” between the upper ends “K” and “K” at both sides of the concave groove is B≧3b, and (3) a relationship between a dimension “a” of a square concave groove expressed by a product of the width “b” of the bottom surface of the concave groove and the depth “h” of the bottom surface portion, and a cross-sectional dimension “A” of the concave groove is A≧2a.
ABSORBENT ARTICLE WITH BODY CONFORMING STRUCTURE
An absorbent article has a top sheet, a back sheet, and an absorbent assembly positioned between the back sheet and the top sheet. The absorbent article includes a fluid intake layer positioned between the absorbent assembly and the top sheet. The fluid intake layer has a rearward-facing arch located in a back portion of the fluid intake layer. The fluid intake layer has an opening. The absorbent article includes a first lateral stiffener and a second lateral stiffener extending along a majority of the longitudinal side edges of the fluid intake layer. The absorbent article includes a first flexure, a second flexure, and a third flexure in a rear portion of the absorbent article.
ABSORBENT ARTICLE WITH PARTIALLY ENCLOSED WAIST CONTAINMENT MEMBER AND METHOD OF MANUFACTURING THEREOF
An absorbent article (10, 110) can include a waist containment member (54) with a first longitudinal side edge (72), a second longitudinal side edge (74), a proximal portion (76), an intermediate portion (77), and a distal portion (78). The proximal portion (76) can be coupled to the chassis (11) of the absorbent article (10, 110). The intermediate portion (77) can be free to move independent of the proximal portion (76) and the distal portion (78) and free to move independent of the body facing surface (19) of the chassis (11) to provide a containment pocket (82) for containing body exudates. The distal portion (78) can be disposed underneath the intermediate portion (77) when the absorbent article (10, 110) is in the stretched, laid-flat configuration. The waist containment member (54) can also include a first lateral tack-down region (83a) and a second lateral tack-down region (83b).
