  • Patent number: 4609580
    Abstract: A floor mat having costs of manufacture consistent with disposability and yet extended properties. The mat comprises a combination of a continuous filament nylon nonwoven wear surface, and absorbent inner layer comprising a mixture of polymeric microfibers and wood pulp, and a liquid impervious film backing layer. The combination is intermittently bonded such as by means of sonic energy and preferably has means for positioning and retaining the mat on a floor surface. Such means may include a holder device or tacky adhesive applied to the bottom film surface. In use the floor mat of the invention may be printed for decorative or promotional purposes and is sufficiently durable to last up to several weeks under high use conditions while yet being economical to produce. Applications for the floor mat include many consumer and industrial situations where protection from inclement weather is desired as well as in industrial clean rooms, laboratories and hospitals.
