Abstract
In a tampon pledget, a quantity of moisture activated material is positioned in contact with, or adjacent to a layer of absorbent material used in forming the pledget. Upon contact with menses, the moisture activated material reacts in one of an endothermic and exothermic manner so that in use, the pledget, when forming part of a tampon can thermally alert a wearer when the pledget has reached its absorbent capacity.
