A dressing for treating a tissue site with negativepressure may comprise a tissue interface comprising a three-dimensionaltextile of polyester fibers and a polymer coating on the polyesterfibers. In some examples, the three-dimensional textile maybe a three-dimensional weave of polyester fibers, and the polymercoating may be hydrophobic. In more particular embodiments, thepolymer coating may be silicone or polyethylene, for example. Thedressing may additionally include a drape disposed over the tissueinterface and a port fluidly coupled to the tissue interface throughthe drape. The tissue interface may be applied over a tissue site,and therapeutic levels of negative pressure may be applied to thetissue site through the tissue interface.
