  • Publication number: 20050244640
    Abstract: The present invention is directed to a coated elastomeric sheet or strands having a polymeric coating applied to both sides. The powder-free polymer coating provides good release and anti-blocking properties to elastic strands, as well as adding to the machinability and end-use properties of the strands. The polymer-coated elastic strands are useful in the manufacture of diapers and other disposable articles requiring flexible elastic-lined openings.

  • Publication number: 20040070510
    Abstract: A moisture monitoring device is provided having a resonant tag and a remote detector. The resonant tag comprises a plastic substrate having holes punched through it, a capacitor plate on one side that is connected to a second capacitor plate and inductor coils on the other side. The resonant tag comprises a live LC circuit having a natural resonant frequency that does not activate the detector. The resonant tag is affixed to absorbing materials in a diaper or other sanitary undergarment. Upon the introduction of moisture into the circuit, the resonant frequency is eliminated as the circuit is deactivated and an alarm in the detector is triggered. At this point it would be apparent to a parent or caretaker that the diaper is wet and in need of replacement.
