The present invention includes novel barrier webs that have certain desirable physical qualities such as water resistance, increased durability, improved barrier qualities and the like. The present invention further comprises a barrier web comprising a web 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 selective binding certain microorganisms, particles or molecules depending upon what binding partners are incorporated into the polymer before application to the fabric.
La présente invention concerne de nouveaux tissus de protection qui ont certaines qualités physiques souhaitables telles que la résistance à l'eau, une durabilité accrue, des propriétés de protection améliorée et similaire. La présente invention concerne en outre un tissu de protection constitué d'un tissu qui a été traité avec une composition polymère thixotrope, durcissable et fluidifiée. Le tissu est sensiblement imperméable aux liquides, perméable aux gaz et imperméable aux micro-organismes. Les tissus de protection de la présente invention sont soit imperméables à tous les micro-organismes, soit imperméables aux micro-organismes de certaines tailles. La présente invention concerne également des tissus qui sont capables de fixer sélectivement certains micro-organismes, particules ou molécules, et ce en fonction des agents liants qui sont incorporés au polymère avant l'application sur le tissu.
