TOPSHEET LAMINATES WITH TACKIFIER-FREE ADHESIVE
Absorbent articles comprising topsheet laminates bonded with substantially tackifier-free adhesives, wherein the topsheet laminates comprise morphological treatments.
Absorbent article
The present invention addresses the problem of providing an absorbent article in which a bonding part for bonding a liquid-permeable layer to an absorbent core has been formed in a low-basis-weight region of the absorbent core and which has all of sufficient flexural rigidity of the bonding part, sufficient bonding strength of the bonding part, and sufficient liquid-absorbing properties. This problem is solved with an absorbent core which comprises a first region that has a given absorbent-material basis weight and second regions (regions 411a, 411b) that have a lower absorbent-material basis weight than the first region, wherein the ratio of the basis weight of a highly absorbing polymer to the basis weight of the absorbent material in the second regions is regulated to 10/100 to 47/100, and compressed parts are formed inside the second regions.
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.
BODILY FLUID ABSORBENT MATRIX AND METHOD FOR MANUFACTURING THE SAME
A bodily fluid absorbent matrix adapted to restrict a wet feeling against the wearer's skin after the absorbent matrix in a bodily fluid absorbent wearing article having absorbed bodily fluids and a method for manufacturing the absorbent matrix. A bodily fluid absorbent wearing article has an absorbent matrix formed of aggregate of bodily fluid absorbent material between a liquid-permeable first sheet and a liquid-impermeable second sheet. The member includes hydrophilic fibers as the bodily fluid absorbent material. Density of the absorbent matrix changes so as to increase from the first sheet toward the second sheet in thickness direction of the absorbent matrix. A planar orientation index of the hydrophilic fibers also changes so as to increase in the thickness direction of the absorbent matrix.
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.
HYDROPHILIZED CELLULOSE ACETATE TOW BAND, AND ABSORBENT MATERIAL PRODUCED USING SAME
A hydrophilized cellulose acetate tow band according to the present invention includes a crimped cellulose acetate tow band, and a hydrophilizing component having an HLB value of 16 or more. The cellulose acetate tow band includes a cellulose acetate having a degree of substitution of 2.0 to 2.6. The cellulose acetate tow band has a total denier of 10000 to 40000 and is crimped in a number of crimps of 30 to 60 per inch. The hydrophilizing component is impregnated on the cellulose acetate tow band in an amount of 0.2 to 2 weight percent relative to the cellulose acetate tow band. The hydrophilized cellulose acetate tow band may further include a textile oil, where the textile oil is impregnated on the crimped cellulose acetate tow band in an amount of 0.2 to 2 weight percent relative to the cellulose acetate tow band, in addition to the hydrophilizing component having an HLB value of 16 or more.
Ultra-thin absorbent article
The present invention generally relates to sanitary absorbent articles and in particular to disposable feminine sanitary absorbent articles that are extremely thin, highly absorbent and have superior structural integrity properties.
REDUCED BASIS WEIGHT ACQUISITION DISTRIBUTION LAYER
Absorbent articles, such as channeled core diapers, including (i) a topsheet; (ii) an acquisition distribution layer (ADL) comprising a first spunbond nonwoven comprising a first plurality of hydrophilic polyolefin fibers, wherein the ADL has a basis weight from about 5 to about 20 grams-per-meter-squared (gsm), such as at least about any of the following: 5, 6, 7, 8, 9, 10, 11, and 12 gsm, and/or at most about any of the following: 20, 19, 18, 17, 16, 15, 14, 13, and 12 gsm; and (iii) an absorbent core including (a) a core warp layer and (b) one or more channels defining one or more troughs, wherein the ADL is located directly or indirectly between the topsheet and the core wrap layer of the absorbent core.
An Absorbent Article with Fluid Control Features
An absorbent article includes a bodyside liner, an absorbent core, and an acquisition layer positioned between the bodyside liner and the absorbent core. Properties of the bodyside liner, absorbent core, and acquisition layer may facilitate fluid flow within a target zone and provide the absorbent article with desired dryness.
GARMENT FOR TREATMENT OF INCONTINENCE
A protective undergarment having an absorbent portion that includes a central absorbent portion having opposing sides, a first gasket portion formed on the central absorbent portion, and a second gasket portion formed on the first gasket portion. In some variations, the protective undergarment may include a pair of briefs having an opening for a wearer's torso and leg openings for each of the wearer's legs. The leg openings may include leg cuffs that may include one or more of: light ruching on or inside the leg cuffs, stretch binding or a stretch seam formed on an outer edge of the light ruching, and/or absorbent binding on the leg cuffs.
