Abstract
A method is disclosed for modifying the physical characteristics of a web which involves passing the web between at least one pair of interengaged rolls to incrementally stretch the web, and then withdrawing the incrementally stretched web from between the rolls under tension. A web modified according to the disclosed method has desirable breathability and liquid impermeability, as well as extensibility and a soft, cloth-like textured surface. One embodiment of the present invention provides a breathable web comprising a microporous film exhibiting an MVTR of at least about 2000 g/m.sup.2 /24hr, a dynamic impact value of less than about 10 g/ m.sup.2, a bubble pressure at least about 45 psi, and an air flow of at least about 2 liters/m.sup.2 /s.
