The present invention is intended to provide the advantages of forming the leg gathers with the liquid impervious film that allow reduction of the used amount of the non-woven fabric while suppressing the deterioration of the texture, and others. The foregoing issue is solved by providing leg gathers that have: an inside non-woven fabric layer constituting a width-direction inner surface; an outside non-woven fabric layer constituting a width-direction outer surface; elastically stretchable gather materials that are provided along the front-back direction between the inside non-woven fabric layer and the outside non-woven fabric layer of at least forward end portions in front-back direction intermediate portions; and a liquid impervious film that is sandwiched between the inside non-woven fabric layer and the outside non-woven fabric layer ranging from a base end to a position nearer a forward end side than the base end, and is configured such that parts of the leg gathers having the liquid impervious film nearer the base end side than the forward end portions constitute non-woven fabric absent parts where the inside non-woven fabric layer does not exist and the liquid impervious film is exposed.

Underpants-type disposable diaper

The present invention provides an underpants-type disposable diaper that has pleats formed in an outer body, which vertically and straightly extend, is excellent in appearance and air permeability, and is excellent in drawing preventing performance of a resilient and elastic member. The above-mentioned object is solved by a method for producing an underpants-type disposable diaper including, in forming stretchable regions, applying an adhesive to both an external surface of an inside layer and an internal surface of an outside layer in the same vertical striped pattern intermittent in an MD direction while transporting the inside layer and the outside layer, and then, fixing resilient and elastic members to the inside layer and the outside layer by bonding the inside layer and the outside layer to each other such that a position of the adhesive on the inside layer in the MD direction and a position of the adhesive on the outside layer in the MD direction are made to match with each other and sandwiching the resilient and elastic members between the inside layer and the outside layer continuously along the MD direction.

Stretchable structure with striped adhesive, method for producing, and absorbent article comprising the stretchable structure

To provide a body fluid absorbent article having a face sheet, a body fluid permeable memberincluding an assembly of fibers in tows, a body fluid retainable absorbent element AB in this order, and a face-side second sheet, which is interposed between the above face sheetand the above body fluid permeable memberwith such a positional relation that the above face-side second sheetis at least partly superposed on the above body fluid permeable member; and embossing is carried out integrally on the above face sheetand the above face-side second sheetwhile embossing is not carried out on the above body fluid permeable member

Sanitary napkin with a tow fiber assembly

[Subject] To obtain a body fluid absorbent article with the perfect protection against the body fluid leakage. [Means for Solving Problem] In the body fluid absorbent, the body fluid retainable absorbent memberA is disposed under the face sheet. Then, the body fluid permeable absorbent member, which include the assembly of fibers in tows, is disposed between the face sheetand the body fluid retainable absorbent memberA.

Body fluid absorbent article

An absorbing article which comprises a liquid permeable top sheet, an absorbing material, a moisture permeable waterproof sheet and a back sheet impermeable to a liquid, being integrated in the above order, wherein an aqueous component indicator comprising a hydrophilic resin coating layer and a notification mark provided on the inner surface of said hydrophilic resin coating layer is provided on the inner surface of the above moisture permeable waterproof sheet.

Absorbent article

An absorbent article including a fiber aggregate formed by opening the tow, a super absorbent polymer particle, and a sheet covering these components. The super absorbent polymer particle are bonded to the sheet with an adhesive that is applied in a continuous plane to the entire surface or the substantially entire surface at least at the portion to be provided with the super absorbent polymer particle in this sheet.

An Absorber and an absorbent article including a fiber aggregate wherein a tow composed of fibers is used as the fiber aggregate, and the compression resilience RC is 45 to 60%. Also, the fiber aggregate has a density of 0.0075 g/cmor less, weight of 0.0075 g/cmor less and a mass of 1 to 15 grams.

Absorber and absorbent article

A shuffling hand feeling and unwanted non-uniform absorption characteristics in the case of using a tow (fiber bundle) are prevented. An absorbent body includes a fiber aggregateformed by opening the tow, a super absorbent polymer, and a sheet covering these components; and includes the super absorbent polymerbonded to the sheetwith an adhesive that is applied in a continuous plane to the entire surface or the substantially entire surface of at least the portion to be provided with the super absorbent polymerin this sheet

Manufacturing facility of absorbent body, absorbent body and absorbent article

An absorbent article for body fluids aimed at utilizing an entire absorbent member efficiently and having a thinner form, a larger absorption capacity and longer wearability as a whole is provided. The absorbent memberhas a contraction materialwhich contracts itself on contacting urine passing through a liquid-permeable surface layer provided on the side facing to the body skin and an absorbent material for body fluidswhich is practically united with the contraction materialis arranged on the upper side of a leak proof layer provided on the side farther from the body skin.
