NONWOVEN LAMINATE BARRIER MATERIAL

摘要

A nonwoven web laminate having improved particulate barrier properties, and particularly improved particulate barrier properties for particles in the size range of between .19 microns and .5 microns, is provided. The particulate barrier properties are improved by subjecting one or more of the layers forming the nonwoven web laminate to corona discharge. The improved particulate barrier properties are further achieved without substantially altering or increasing the amount of surface charge on the nonwoven web laminate. The laminate may be formed into protective garments including coveralls which may be disposed of after use.
