Abstract
A diaper is provided having a facing layer comprising a fibrous nonwoven web having an exceptionally low weight per unit area for its loft and stength characteristics. The facing layer is made from an air laid web of mixed long and short fibers by impregnating the web with a volatile liquid composition containing a binder, rapidly vaporizing the volatile portions of the composition to cause puffing of the web while setting the web in puffed condition by solidification of the binder and thereafter splitting the puffed web into portions of lesser thickness and utilizing at least one of said portions as said facing layer.
