ABSTRACT:
A porous web having a permanent humidity detecting sensor is disclosed in which a metal salt is permanently bonded in the porous web matrix. The metal salt undergoes a color change from its hydrated to its dehydrated state to detect a change in humidity of a surrounding environment. Nonwoven fibrous webs having a permanent humidity detecting sensor are especially adapted for containing materials such as fabric softeners that may be released upon the conditions of a conventional clothes dryer for treatment of the clothes and visual detection of the release of softener by color change of the humidity sensor.
