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) 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

An absorbent body in absorbent articles that causes exudates to disperse in a planar direction and a method of producing the same. The absorbent body has an absorbent core material covered with a cover sheet. The core material has a mass per unit area of 650 g/mor less and includes a first liquid absorbent layer containing hydrophilic fibers and superabsorbent polymer particles in a mixed state and a second liquid absorbent layer containing the hydrophilic fibers but none of the superabsorbent polymer particles, wherein the first liquid absorbent layer and the second liquid absorbent layer are overlap with each other and the hydrophilic fibers are in contact with each other between the first liquid absorbent layer and the second liquid absorbent layer.

Absorbent body in absorbent article and method for producing the same

A disposable diaper is formed in one of front and rear waist regions with first wings which are elastically stretchable in a waist-surrounding direction and these first wings are provided on respective body facing surfaces with first fastener elements. The other waist region is provided on its undergarment facing surface with, in addition to second fastener elements, anti-slip zones exhibiting a desired average kinetic frictional force relative to the body facing surface of the first wings.

Disposable diaper

An absorbent panel for pet animals such as dogs and cats comprising a liquid-permeable topsheet, a liquid-impermeable backsheet and a liquid-absorbent core panel therebetween, the core panel comprises a relatively thin central region and a relatively thick side region.

Absorbent panel for pet animals

A material and a method for preparing the same for treating excretions of pet animals comprising: 100 parts by weight of substrate (A) selected from an inorganic powder, short organic fibers, crushed cellulose, or granulated forms thereof coated with from 5-300 parts by weight of a water-absorbent resin/fiber composite (B), the composite (B) being a mixture of a water-absorbent resin fine powder, a fibrous substance and optionally a hydrophilic thermoplastic substance.

Material for the treatment of pet excretion and method of producing the

A material for treating excretions of pet animals which is obtainable by combining pulp (A), inorganic substance (B), guar gum (C) and optionally water-absorbent resin (D) to form guranules. The weight ratios of (A) to (B) to (C) to (D) is 15-55:15-55:5-40: 5-45. The treating material is capable of absorbing liquids from excretions quickly, forming into clumps when absorbing liquid and maintaining the shape of the clump even when handled for removal.

Materials for the treatment of pet excretions

An absorbent composite panel comprising a liquid-absorbent panel and a liquid-impermeable backsheet, wherein the top surface of the absorbent panel is partially covered along its peripheral edges with a liquid-impermeable overflow barrier strips which are then bonded integrally to the backsheet along their outer side edges and each inner side edge of the overflow barrier strips is spaced by each spacer from the top surface of the absorbent panel by a desired distance.

Absorbent composite panel for pet animal

The present invention discloses an absorbent composite panel to be laid on a urination tray for pet animals such as cats and dogs, the composite panel comprising a liquid-permeable topsheet, a liquid-impermeable backsheet and a liquid-absorbent core disposed between these two sheets, the absorbent core comprising a plurality of core elements intermittently arranged independently of one another and the top- and backsheets being bonded together over zones defined between each pair of adjacent core elements so that a selected portion of the composite panel may be cut off from the remainder.

Granular absorbent material for a pet animal, each grain thereof comprising a core formed from absorbent material, a liquid-impermeable partition sheet parting the core into upper and lower halves and a liquid-permeable sheet covering the core.
