Articles of barrier webs

摘要

A barrier web comprising a fabric that has been treated with a curable shear thinned thixotropic polymer composition, the fabric being adapted to be substantially impermeable to liquids, permeable to gases and impermeable to microorganisms. The barrier webs of the present invention are either impermeable to all microorganisms or are impermeable to microorganisms of certain sizes. The present invention also includes fabrics that are capable of either selectively binding certain microorganisms, particles or molecules depending upon what binding partners are incorporated into the polymer before application to the fabric.
