METHOD OF MAKING A CLOTH-LIKE MICROPOROUS LAMINATE OF A NONWOVEN FIBROUS WEB AND THERMOPLASTIC FILM_HAVING AIR AND MOISTURE VAPOR PERMEABILITIES WITH LIQUID-BARRIER PROPERTIES

摘要

A cloth-like microporous laminate of a nonwoven fibrous web and thermoplasti c film is made by lamination of a microporous-formable film composition and a nonwoven fibrous web followed by incremental stretching to form the cloth-li ke microporous laminate. The cloth-like microporous laminate has air and moistu re vapor permeabilities, but acts as a barrier to the passage of liquids. The cloth-like laminates are especially useful in fabricating garments in order to provide the breathable qualities of air and moisture vapor transmission with liquid-barrier properties. Such garments include baby diapers, baby training pants, catamenial pads and garments, and the like where moisture vapor and a ir transmission properties, as well as fluid barrier properties, are needed.
