Abstract
Abstract THE FLUFF-TYPE PAD PORTION OF A DIAPER IS SO REINFORCED AS TO INCREASE PIN STRENGTH AND TO PRECLUDE TEARING EVEN IF EXTREMELY LIGHTWEIGHT PAPER OR FILMS OF SYNTHETIC RESIN ARE USED TO ENCLOSE THE FLUFF. THE REINFORCEMENT PREFERABLY COMPRISES A SCRIM MADE EITHER OF WOVEN OR NONWOVEN FABRIC AND INCORPORATED IN THE PAD EITHER AT THE TOP OR BOTTOM OR AT AN INTERMEDIATE LEVEL AND EXTENDING CLOSE ENOUGH THE SIDE OR END MARGINS OF THE DIAPER TO CONNECT WITH AND STRENGTHEN THE PORTIONS WHICH RECEIVE A DIAPER PIN. THE PREFERRED SCRIM COMPRISES MONOFILAMENTS WHICH ARE FLEXIBLE AND YIELD UNDER TENSION AND ARE ATTACHED TO EACH OTHER AT JUNCTION POINTS.
