Description

The present invention relates to absorbent articles.

Generally, an absorbent article is composed of a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorber arranged between the top sheet and the back sheet, whereby urine, etc. Body fluid is absorbed by the absorber through the top sheet. There are various types of absorbent articles such as tape-type disposable diapers, pants-type disposable diapers, urine absorbing pads, and light incontinence pads, regardless of whether they are for adults or infants. ..

It was common to use fluff pulp and super absorbent polymer (also referred to as Super Absorbent Polymer, also called SAP) together for the absorbent body constituting these absorbent articles, but the feeling of wearing, the appearance and the skin feel when worn. A so-called super absorbent sheet (also referred to as a SAP sheet) made of a non-woven fabric as a base and a super absorbent polymer may be used as an absorber for the purpose of improving the like and reducing the return of urine. There have been various studies.

For example, Patent Document 1 includes a first sheet and a second sheet to which an adhesive is applied, and a superabsorbent polymer arranged between the first sheet and the second sheet, and at least on the second sheet. The application of the adhesive is intermittent in the areas corresponding to the plurality of regions of the adhesive, and the adhesive is continuously applied in the longitudinal direction to the areas facing the first sheet on both sides in the width direction of the superabsorbent polymer. And a superabsorbent sheet characterized in that the superabsorbent polymer is arranged in stripes along the longitudinal direction is disclosed.

Further, Patent Document 2 discloses an absorbent body in which two superabsorbent sheets are folded along the longitudinal direction, and the two superabsorbent sheets are arranged so that their folds face each other. Further, Patent Document 3 discloses an auxiliary absorbent article including a polymer sheet having alternating regions where water absorbent resin exists and regions where water absorbent resin does not exist in the width direction.
