NONWOVEN WEBS HAVING IMPROVED BARRIER PROPERTIES

摘要

A laminate is generally provided having alcohol repellency properties. In one particular embodiment, the laminate includes a meltblown web bonded to a spunbond web (e.g., a SM laminate, a SMS laminate, a SMMS laminate, etc.). A fluorinated polymeric coating is attached to the surface of the spunbond web (e.g., grafted). The fluorinated polymeric coating comprises a perfluoroalkyl(alkyl) (meth)acrylate monomer polymerized on the surface of the spunbond web via exposure to a low frequency energy source. Tthe perfluoroalkyl(alkyl) (meth)acrylate monomer has a perfluoroalkyl side groups comprising -(CF2)Z-F, where z is an integer from 1 to 6. The laminate has an alcohol repellency of greater than 80%.
