Abstract
Abstract A re-useable diaper is provided having two fabric panels joined to each other by means of a non-wicking, waterproof web, said panels being superimposable by folding along said web to orient the same as an inner, body contacting panel and an outer or visible panel, and moistureproof film means disposed between said superimposed panels and extending to said web to prevent moisture accumulated in said inner panel from reaching said outer panel. This assemblage permits the diaper to be used without the need of an outer protective garment such as ''''rubber pants'''', since the non-wicking web and the moistureproof overlay prevent moisture from being transmitted from the fabric ply placed against an infant to the outermost fabric ply. In other embodiments, the diaper can be folded in various sizes to accommodate the increased size of an infant during growth, and can also be used in larger sizes for adults requiring such protection for medical purposes.
