Diapers with moisture detection and process and apparatus for making them
First Claim
1. A method of manufacturing a diaper, comprising:
- forming a liquid-impermeable backing sheet having an exterior surface and an interior surface so as to form an exterior of the diaper and an interior of the diaper;
bonding a liquid-absorbing arrangement to the interior surface of the backing sheet;
bonding an elastic pocket to the exterior surface of the backing sheet to contain a detector module;
placing sensing electrodes within the interior of the diaper and within the interior surface of the backing sheet in contact with the liquid absorbing arrangement that is bonded to the backing sheet, and in a direction to extend opposite the elastic pocket that is bonded to the exterior surface of the backing sheet so as to allow the sensing electrodes to couple only capacitively to the detector module.

Abstract
A method of manufacturing a diaper includes constructing a backing sheet having an exterior surface and an interior surface so a to form an exterior of the diaper and an interior of the diaper, bonding a tissue layer to the interior surface of the backing sheet, bonding an elastic pouch to the exterior surface of the backing sheet to contain a detector module, and placing sensing electrodes within the interior of the diaper along the interior surface of the backing sheet in contact with the tissue layer that is bonded to the backing sheet, and in a direction to extend opposite the elastic pouch that is bonded to the outside of the backing sheet so as to allow the sensing electrodes to couple capacitively to the sensor module.
