An objective is to provide an absorbent article that can prevent backflow and can reduce water retention in a front sheet as much as possible. In an incontinence padfor use with a medium or larger volume that absorbs 20 cc or a larger volume of urine, a front sheetis formed by coating a water repellent on a spunlace nonwoven fabric that is made of 100 wt. % of cotton fiber. On a skin facing surface side, in a plan view, recess part linesof a diamond-shaped lattice pattern are formed from many first recess part linesthat go along a predetermined inclination angle direction and are formed with a constant gap in the pad longitudinal direction and many second recess part linesthat go along the inclination angle direction obtained by reversing the first recess part linesin a width direction by the pad longitudinal direction and are formed with a constant gap in the pad longitudinal direction, partition areasof a diamond-shaped lattice shape partitioned by these recess part linesare arranged adjacently in the longitudinal direction and the width direction. Furthermore, many open holespenetrating through both sides are formed at least at an excretion hole corresponding part H.

Absorbent article

In an absorbent article for incontinence using cotton fiber for a front-surface sheet, a diffusing range of liquid in the front-surface sheet is made to be a predetermined range or less, thereby eliminating a sticky feeling of the surface, and reducing water retention of the front-surface sheet so as to cause urine to diffuse in the front-surface sheet rapidly.

Absorbent article for incontinence

A water repellent is applied to a spun lace nonwoven fabric in which a surface sheet comprises 100% by weight of cotton fibers, and a large number of openings that penetrate the obverse and reverse surfaces are formed in at least a portion that corresponds to an excretory opening. A heat-fusible fiber sheet is disposed adjacent to the absorber side surface of the surface sheet. A plurality of adhesive portions are formed between the surface sheet and the heat-fusible fiber sheet along the longitudinal direction and spaced apart in the widthwise direction of an incontinence pad. A compressed groove recessed from the outer surface of the surface sheet toward the absorber is formed close to the adhesive portions.

An absorbent article that prevents back flow and that uses cotton fibers in the surface sheet. The absorbent article is an incontinence pad having at least a medium volume for absorbing at least 20 cc of urine. A surface sheet is formed by coating, with a water-repellent, a spunlace non-woven fabric comprising 100 wt % of cotton fibers. The skin-facing surface side is provided with: a plurality of protrusions that extend along the longitudinal direction of the incontinence pad and are formed with gaps therebetween in the widthwise direction; and a plurality of recesses that extend along the longitudinal direction of the incontinence pad and are formed between adjacent protrusions. The recesses are formed thinner than the protrusions. A plurality of openings, which penetrate the incontinence pad from the front to the rear thereof, is formed along the recesses in at least a section (H) corresponding to an excretory opening.

To provide an absorbent article that uses a cotton fiber in a front-surface sheet, prevents rebounding, improves an absorption speed, and reduces a diffusion range of urine in the front-surface sheet. An incontinence padhaving a medium or larger volume that absorbs 20 cc or a larger volume of urine is provided. A front-surface sheetis a spunlace nonwoven fabric made of 100% cotton fiber by weight, is coated with a water repellent agent and has many front-face/back-face penetrating openingsin a region containing a part corresponding to an excreting hole. The absorber is made of a pulp fiber that does not contain synthetic fiber and a superabsorbent polymer, a basis weight of the pulp fiber being 75 to 300 g/m, a basis weight of the superabsorbent polymer being 85 to 185 g/m, and a ratio of the pulp fiber and the superabsorbent polymer being pulp fiber:superabsorbent polymer=70 to 30% by weight:30 to 70% by weight.

Incontinence absorbent article with cotton fiber front-surface sheet

There is provided an absorbent article with its front-surface sheet composed of cotton fibers by which liquid reversion is prevented and water retention on the front-surface sheet is minimized. An incontinence padis provided that is configured to absorb urine at medium or more volume that is 20 cc or more. A front-surface sheetis formed of a spunlace nonwoven fabric 100 wt % of which is composed of cotton fibers and which is coated with a water repellent agent, and has, at least at a portion corresponding to an excreting hole, numerous front-face/back-face penetrating openingsthat are longer shaped in the longitudinal direction of the incontinence pad. The cotton fibers form numerous longitudinal streaksand numerous lateral streaks, the longitudinal streaks extending along the longitudinal direction of the incontinence padand being formed with an interval in the width direction of the incontinence pad, and the lateral streaks extending along the width direction of the incontinence padand connecting together the longitudinal streaks formed with an interval in the longitudinal direction of the incontinence pad. The openingsare formed within portions surrounded by the longitudinal streaksand the lateral streaks. The longitudinal streakshave more fibers and are formed at a higher density than the lateral streaks
