COVER FOR CONTAINING AND ABATING ODIFEROUS ORGANIC EMANATIONS, COMPRISING A NONWOVEN LAYER AND TWO POROUS POLYMERIC LAYERS, AS WELL AS ANATASE AS PHOTOCATALYST, AND CONTAINMENT SYSTEM USING SUCH COVER

摘要

An odiferous organic compounds cover having an inner surface and an outer surface. The cover contains a thermoplastic non-woven layer having a first side and a second side and comprising thermoplastic fibers. The first side of the non-woven layer forms the inner side of the cover, has a contact angle with water greater than about 70°, and is non-wicking. The cover contains a UV barrier layer on the second side of the non-woven layer. The UV barrier layer has a thickness of between one to three times the diameter of the thermoplastic fibers of the non-woven layer and the UV barrier layer comprises discontinuities forming microchannels though the layer thickness. The cover also contains an odor mitigation layer on the UV barrier layer on the side of the barrier layer opposite the non-woven layer. The odor mitigation layer comprises a UV translucent polymer and anatase titanium dioxide.
