Antimicrobial roll-up floor cover

Abstract

A temporary roll-up floor cover includes a rugged upper layer that is impervious to water and pervious water vapor, and a lower antimicrobial wicking layer that quickly spreads water while transmitting water vapor, to facilitate evaporation of moisture that gets under the cover. The cover may also include one or more of a central layer containing a microporous membrane, a coating or film layer which may be perforated, and a stiffener lattice that resists folding, gathering and puckering without preventing the cover from rolling up. The coating layer adds additional resistance to folding, gathering and puckering without preventing the cover from rolling up. The coating may be perforated to increase water vapor transmission through the cover. One or more antimicrobial agents may be incorporated into the floor cover, for example, into the wicking layer during extrusion of the airlaid mat forming the wicking layer.
