<p>A reusable wetness indicating cloth diaper which uses a thermally sensitive indicator to indicate that the diaper has become soiled. The diaper of the present invention comprises material (10) which at least partially thermally insulates the outer surface (5) from said inner surface (47) and an indicator on the outer surface which provides a visual indication when the outer surface has a temperature above a given threshold. The present invention utilizes a thermochromic ink to provide the indication of a temperature change in the diaper. Conventional silk screening techniques are applied to the thermochromic ink forming a plurality of discrete indicators which provide a visual indication when the outer surface has a temperature above a given threshold.</p> |
