NONWOVEN WEBS HAVING IMPROVED BARRIER PROPERTIES.

摘要

Methods of manufacturing a nonwoven web having alcohol repellency properties are provided. A plurality of perfluoroalkyl(alkyl) (meth)acrylic monomers can first be deposited on a surface of the nonwoven web, and subsequently exposed to a RF plasma to polymerize the monomers on the surface of the nonwoven web to form a fluorinated polymeric coating. The perfluoroalkyl(alkyl) (meth)acrylic monomers include perfluoroalkyl(alkyl) (meth)acrylate esters having a perfluorinated carbon end group of 1 to 6 carbon atoms Nonwoven webs are also generally provided that have an alcohol repellency of greater than 80%.
