    • Water content sensing and informing system for the disposable diaper composed of a water permeable inner sheet, a water absorber and a water impermeable outer sheet, comprises a water content sensing means consisting of a water impermeable sheet, and a first and second metal layers, the first metal layer being formed on one side surface of the water impermeable sheet, and the second metal layer being formed on the other side surface of the sheet and an informing means, electrically connected to the above two metal layers, for informing that the water content in the diaper exceeds a specific level in response to the change of the electric conductivity between the first metal layer and the second metal layer. The water content sensing means is disposed in any suitable section in the diaper such as in the water absorber, between the water absorber and the water impermeable outer sheet, or between the water absorber and the water permeable inner sheet and is adapted to be assembled with the diaper by means of a pressure welding or an adhesive at the same manufacturing process.
    • 由透水内层,吸水体和不透水外层构成的一次性尿布的含水量检测和通知系统包括由不透水片组成的含水量检测装置和第一和第二金属层, 第一金属层形成在不透水性片材的一个侧面上,第二金属层形成在片材的另一个侧面上,以及与上述两个金属层电连接的通知装置,用于通知含水量 在第一金属层和第二金属层之间的电导率的变化中,尿布超过特定水平。 水分检测装置设置在尿布中的任何合适的部分中,例如在吸水器,吸水器和不透水的外部片之间,或在吸水体和水可渗透的内层之间,并且适于与 该尿布通过压力焊接或粘合剂在相同的制造过程中。
