The object of the present invention is to provide a method of reducing the odor of urine; and an article functioning to reduce the odor of urine. The present invention relates to the method comprising using a compound(s) reactive with aldehydes to thereby reduce the urine odor. Moreover, the present invention relates to the article, especially one for body fluid absorption, which functions to reduce the odor of urine by having compounds reactive with aldehydes to be present in absorption articles. As the compounds reactive with aldehydes, organic amines, organic amine salts, compounds producing organic amines by the reaction with discharges, organic amines, amide compounds, and compounds having a mercapto group can be used.

Method of reducing urine odor and article functioning to reduce urine odor

Disclosed is an antibacterial sheet including an antibacterial composition and a sheet-like base member with the antibacterial composition attached thereto. In the antibacterial sheet, a composition including an antibacterial agent and a water-soluble thermoplastic polymer which is solid at a normal temperature and which dissolves in a body fluid is used as the antibacterial composition.

Antibacterial sheet and absorbent article

Provided is an absorbent article including a main body having a liquid-pervious top sheet, a back sheet and an absorbent core sandwiched between the top sheet an the back sheet; a layer containing a skin-protective ingredient; and a support layer for covering the ingredient-containing layer. The ingredient-containing layer and the support layer are provided on the surface of the main body to be in contact with the skin of a wearer. The solubility in water of the support layer is promoted at 25&#xb0; C. or higher, and/or the moisture absorbability or the solubility in water of the support layer is promoted at a relative humidity of at least 30%.

Absorbent article containing skin-protective ingredient

An absorbent article contains a hydrophilic fiber processed by a water-soluble deodorant containing a graft polymer having a deodorant functional group. This constitution ensures to have large deodorizing function per unit weight, compared to a particulate deodorant. Consequently, the constitution allows to decrease a weight of the deodorant and to excel in deodorizing function. Moreover, it is unnecessary to fix the deodorant and easy to compound with the absorbent article. Therefore, it allows to obtain an absorbent article having excellent aesthetics and cleanness.

Absorbent article for reducing urine odor

The present invention relates to an absorbent article such as a disposal diaper, sanitary napkin, or the like which can reduce odor and dermatitis (rash) generated when such an absorbent article is worn. The absorbent article comprises a compound assimilated only by microorganisms in the normal flora of the skin useful and/or harmless to the human body and preferably such a compound assimilated only by microorganisms in normal flora of the skin useful and/or harmless to the human body is glucooligosaccharide.

Absorbent article for controlling normal flora of the skin

A topsheet for a disposable absorbent article including a first plastic film layer, a second plastic film layer and a fibrous assembly layer disposed between these two layers. The first plastic film layer includes a plurality of first plane regions spaced one from another and extending in parallel one to another in one direction and the second plastic film layer includes a plurality of second plane regions spaced one from another and extending in parallel one to another in the one direction. Of the first and second plane regions, at least the first plane regions are formed with bridge-like regions and first rising regions.

A topsheet for a disposable absorbent article that includes a first plastic film layer, a second plastic film layer and a fibrous assembly layer disposed between these two layers. The first plastic film layer includes a plurality of first plane regions spaced apart from one another that extend parallel to one another in one direction and the second plastic film layer includes a plurality of second plane regions spaced apart from one another that extend parallel to one another in the one direction. Of the first and second plane regions, at least the first plane regions are formed with bridge-like regions and first rising regions.

A topsheet for a disposable absorbent article that includes a first hydrophobic plastic film layer, a second hydrophobic plastic film layer and hydrophobic thermoplastic synthetic fibrous layer disposed between the two layers. The first hydrophobic plastic film layer includes a plurality of first plane regions spaced apart from one another that extend parallel to one another in one direction and the second hydrophobic plastic first layer includes a plurality of second plane regions spaced apart from one another that extend parallel to one another in the one direction. Of the first and second plane regions, at least the first plane regions are formed with bridge regions and first rising regions.

A composite sheet adapted to be used as a stock material for disposable garments comprises a film-like upper layer and a lower layer formed by a fibrous assembly. The upper layer is formed with a first surface region having plane zones and aperture arrays and a second surface region in the form of a depression. The lower layer has its density higher in a region immediately underlying the second surface region than in a region immediately underlying the first surface region. The composite sheet including such constituent features is suitable as stock material for disposable garments which require a soft touch and a rapid permeation of body fluids discharged on the garments.

Flexible composite sheet for disposable garment

A flexible sheet for a disposable garment includes a plastic sheet and a fibrous assembly joined to a lower surface of the plastic sheet, the plastic sheet includes a plurality of flat zones, a plurality of slit zones, bridge zones across the slit zones and rising zones rising on the upper surface of the plastic sheet repeating rise and fall substantially in saw-tooth-shape, and component fibers of the fibrous assembly partially extend upward in the slit zones.
