Abstract:

The present invention provides a nondisposable diaper which includes a top section and a bottom section. The top and bottom sections are attached by discontinuous perimeter stitching along perimeter ends of the top and bottom section. The perimeter stitching defines first and second openings which permit air to more freely flow between inside surfaces of the top and bottom sections and thereby permit the nondisposable diaper to dry faster. The top and bottom section further include respective outside and inside layers with an absorbency pad secured between the outside and inside layers. The absorbency pad is secured within the nondisposable diaper so that the stitching is not exposed to outside contact.
