Abstract
An extensible water impervious laminated material having an improved hydrostatic head at higher extension is described. A preferred embodiment comprises an inner creped hydrophobic microfine fiber structure sandwiched between and bonded to two reinforcing layers of nonwoven fibers, said microfine fiber structure comprising at least one ply of microfine fibers having a fiber diameter of up to 10 microns. This material is especially useful as an operating room gown.
