    摘要: A cloth-like microporous laminate of a nonwoven fibrous web and thermoplastic film is made by lamination of a microporous-formable film composition and a nonwoven fibrous web followed by incremental stretching to form the cloth-like microporous laminate. The cloth-like microporous laminate has air and moisture 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 air transmission properties, as well as fluid barrier properties, are needed.

    摘要: A totally biodegradable and/or compostable soft cloth-like composite of totally biodegradable and/or compostable film and totally biodegradable and/or compostable nonwoven and method of manufacture. A totally biodegradable and/or compostable nonwoven fibrous web and a totally biodegradable and/or compostable film are laminated. The laminate is incrementally stretched to produce a totally biodegradable and/or compostable laminate that is softer than that produced when the biodegradable and/or compostable nonwoven web is bonded to the biodegradable and/or compostable film. The soft cloth-like features of the invention are desired in a number of applications including diapers, pants, surgical gowns, sheets, dressings, hygienic products, and the like.
