A crotch member of a disposable under garment is joined to central portions of a symmetrical ventral member and a symmetrical dorsal member. A crotch side edge of the ventral member includes a recessed line symmetrically recessed toward a waist side edge between a center line and left and right end portions of the ventral member. The recessed line includes bottom portions each closest to the waist side edge located at a position closer to the left and right end portions than the center line. A crotch side edge of the dorsal member include a protruding line symmetrically protruding away from a waist side edge between a centerline and left and right end portions of the dorsal member. The protruding line includes top portions farthest away from the waist side edge located at a position closer to the centerline than the left and right end portions.

A sheet conveyance device for conveying, along a conveyance path, a sheet in which a given region from an obverse surface toward a reverse side thereof is composed of a non-woven fabric, and a powder supply device for supplying a powder to at least a partial zone of the sheet, are provided. Further, a fiber-raising device for raising fibers in at least part of the powder supply zone of the sheet is provided on the conveyance path at a position upstream of the powder supply device in a conveyance direction of the sheet.

Disclosed is a diaper for sensing urine and feces including a waterproof cover, an absorbing layer located on the inner side of the waterproof cover, and a lining layer located on the inner side of the absorbing layer, wherein the lining layer includes multiple conductive sensing lines positioned on the inner surface of the lining layer that makes contact with the human body, wherein the conductive sensing lines are arranged spaced apart from each other, wherein at least one of the electrical resistance, capacitance, and inductance between the conductive sensing lines changes upon contact between the conductive sensing lines and urine or feces.

Garment-like absorbent articles are disclosed. The garment-like absorbent articles may include two nonwoven components that have coordinating and/or substantially similar repeat patterns of apertures and/or bonds. The two nonwoven components may also have certain repeat unit areas, repeat unit width, and repeat unit lengths to aid in softness and to provide improved aesthetic appearance to consumers.

A method for inspecting absorbent articles is provided. The inspection is performed using an inspection algorithm generated with a convolutional neural network having convolutional neural network parameters. The convolutional neural network parameters are generated by a training algorithm. Based on the inspection, characteristics of the absorbent articles, such as defects, can be identified. Absorbent articles having identified characteristics can be rejected, or other actions can be taken.

A diaper state change notification device has a power source, a micro controller capable of generating a notification, a wireless communications chip, and one or more sensors incorporated in the device or coupled thereto, characterized in that the notification device is attached to or otherwise embedded within a diaper and generates and sends a notification to a monitoring entity upon sensor detection of a diaper state change from a fresh diaper state to a soiled diaper state.

An underpants-type disposable diaper includes outer members 12F and 12B having stretchable regions A2 and A3 disposed adjacent to the inner edges of the side seal portions 12A in the width direction. The stretchable regions A2 and A3 include multiple elongated elastically stretchable members 19 disposed between two sheet layers 12S and 12H at predetermined intervals in the front-back direction and extending in the width direction. The elastically stretchable members 19 each include two fixed ends 19f fixed to the two sheet layers 12S and 12H, and the section between the fixed ends 19f is unfixed to the two sheet layers 12S and 12H. The two sheet layers 12S and 12H are welded into sheet bonding sections 20, at positions between the elastically stretchable members 19 in the stretchable regions A2 and A3 adjacent is the front-back direction. No sheet bonding section protrudes from the side seal portion in the stretchable regions A2 and A3.

The present disclosure relates to absorbent articles including elastic laminates, and more particularly, to methods and apparatuses for making absorbent articles having elastic laminates in front and/or back waist regions with frangible pathways.
