  • Publication number: 20120165774
    Abstract: In a disposable wearing article, a first waist region is elasticized and formed of an inner sheet and an outer sheet. The non-skin-facing side of the outer sheet is formed substantially over its entire area with a plurality of thermocompression-bonded spots regularly and intermittently arranged at predetermined intervals. The outer sheet has non-thermocompressed regions surrounded by a plurality of thermocompression-bonded spots. A fibrous layer lying at least on the outer surface of said outer sheet is formed of thermal adhesive crimped fibers which are bonded together by thermocompression-bonding treatment in the thermocompression-bonded spots. The outer sheet and the inner sheet are bonded to each other by adhesive applied on at least one of respective opposite surfaces thereof so that the crimped fibers in the non-thermocompressed regions may protrude outward in a thickness direction of the outer sheet as the inner sheet contracts in the direction of the transverse axis Q.

  • Patent number: 8183429
    Abstract: A composite sheet which has a low basis weight, can be prevented from breaking during the production of an absorbent article or in use, and is good to the touch. The composite sheet is a sheet formed by bonding a stretch nonwoven fabric to a nonstretch nonwoven fabric with an adhesive. The stretch nonwoven fabric is bonded in a stretched state to the nonstretch sheet. The stretch nonwoven fabric has, on each side, strip-form sparse regions and strip-form dense regions alternately formed. The sparse regions and dense regions on one side are alternately formed in a second direction so that the dense regions on this side do not overlie the dense regions on the other side. The composite sheet has a maximum breaking strength of 20 N/50 mm or higher.

  • Publication number: 20100228210
    Abstract: An absorbent article, preferably a disposable absorbent article such as a diaper, is disclosed having an absorbent core which imparts increased wearing comfort to the article and makes it thin and dry. The absorbent core useful for an absorbent article comprises a substrate layer, a discontinuous layer of absorbent material, and a layer of thermoplastic material. A second surface of the discontinuous layer of absorbent material is in at least partial contact with a first surface of the substrate layer. Portions of a second surface of the layer of thermoplastic material are in direct contact with the first surface of the substrate layer and portions of said second surface of the layer of thermoplastic material are in direct contact with a first surface of the discontinuous layer of absorbent material. A process for providing a storage layer for an absorbent core useful in an absorbent article is further disclosed.

  • Patent number: 7727212
    Abstract: An absorbent article worn in the groin area, in which, when a compressive force is received from a lateral direction, a main absorbent region can oppose an excretion area of a wearer's body without twists or wrinkles occurring, and when the compressive force is relaxed, the article easily recovers to its original shape. An absorbent body provided in the absorbent article has a main absorbent region, reinforcing regions, and buffer regions. The bending stiffness of the reinforcing regions and the main absorbent region is larger than that of the buffer regions. When compressive force is received from a wearer's thigh areas in the lateral direction, the reinforcing regions that are positioned to the left and right deform in a curved shape, and the buffer regions that are to the left and right are compressed. The main absorbent region does not easily deform, and maintains a tight fit.
