High Bulk Composite Sheets

September 15, 2009

Patented is a multi-layer composite sheet comprised of a shrinkable layer intermittently bonded to a gatherable layer with the bonds separated by a specified distance so that the shrinkable layer can shrink and at the same time gather the gatherable layer between the bonds. A process for preparing multi-layer composite sheets by intermittently bonding a shrinkable layer to a gatherable layer with the bonds separated by a specified distance causes the shrinkable layer to shrink while at the same time gathering the gatherable layer between the bonds. Preferably, the shrinkable layer comprises an array of fibers or nonwoven web comprising fibers having latent spiral crimp.
