Title
(EN) COATED BARRIER FABRIC FOR A REUSABLE MEDICAL PRODUCT
Abstract
(EN)

A coated barrier fabric for use in a reusable medical product (e.g., surgical gown, surgical drape, etc.) is provided and has two woven or knitted plies. Each of the two plies are coated on one side with a non-fluorine containing polymer and retain similar comfort and feel of uncoated woven or knitted fabrics. The coated sides of the plies face each other (i.e., inwardly) in the interior of the barrier fabric. Because of the orientation of the plies, the coated sides of the plies can come into direct contact with and move freely against each other within the interior of the barrier fabric. The coating on each of the plies is protected from exterior and environmental factors, including repeated institutional laundering/autoclave cycles, that could abrade and degrade the coating. Thus, the useful life of the reusable medical product including the barrier fabric is extended.
