Woven face polyvinyl chloride floor covering
View Patent ↗The floor covering includes multiple layers including a non-woven base layer, a VAE precoat applied to the non-woven woven base layer and overlaid by a first PVC layer. A fiberglass mat is applied over the first PVC layer and a second PVC layer is applied over the mat. A woven PVC layer is laminated by heat and pressure to the underlying second PVC layer. The woven PVC layer comprises monofilament or multifilament cores, preferably but not limited to, polyester filaments overlaid by a PVC coating.
1. A floor or wall covering comprising:
a non-woven polyester base layer;
a vinyl acetate emulsion pre-coat applied to the base layer;
a first polyvinyl chloride layer overlying and in contact with the vinyl acetate emulsion pre-coat layer;
a non-woven mat overlying and in contact with the first polyvinyl chloride layer;
a second polyvinyl chloride layer overlying and in contact with the mat; and
a prestabilized woven polyvinyl chloride layer overlying and in contact with the second polyvinyl chloride layer and forming a face layer for the covering.
2. A covering according to claim 1 wherein said mat is formed of fiberglass.
3. A covering according to claim 1 wherein the first and second polyvinyl chloride layers are bonded to one another.
4. A covering according to claim 1 wherein the first and second polyvinyl chloride layers are integrally bonded to one another.
5. A covering according to claim 1 wherein the woven polyvinyl chloride layer is bonded to said second polyvinyl chloride layer.
6. A covering according to claim 1 wherein the woven polyvinyl chloride layer includes yarns having at least one polyester filament precoated with polyvinyl chloride.
7. A covering according to claim 1 wherein the woven polyvinyl chloride layer includes a core formed of a multifilament polyester coated with polyvinyl chloride.
8. A covering according to claim 1 wherein the woven polyvinyl chloride layer includes at least one core yarn coated with polyvinyl chloride.
9. A covering according to claim 1 wherein the woven polyvinyl chloride layer includes yarns having a monofilament core.
10. A covering according to claim 1 wherein the woven polyvinyl chloride layer includes yarns having a multifilament core.
11. A covering according to claim 1 wherein the woven polyvinyl chloride layer includes yarns coated with polyvinyl chloride, the yarns being selected from the group consisting of a polyester, nylon, wool, acrylic, cotton, modacrylic, polylactic acid.
12. A covering according to claim 1 wherein the covering is moisture-impermeable.
13. A floor or wall covering comprising:
a non-woven polyester base layer;
a first polyvinyl chloride layer overlying the base layer;
a non woven mat overlying the first polyvinyl chloride layer;
a second polyvinyl chloride layer overlying the mat; and
a woven layer overlying the second polyvinyl chloride layer and forming a face layer for the covering, said woven layer including yarns having at least one polyester filament coated with polyvinyl chloride; and
a pre-coat overlying and in contact with the base layer, said base layer including a non-woven polyester, said non-woven base layer and the pre-coat each having a weight of 4–40 oz/yd 2 , said first and second polyvinyl chloride layers each having a weight of 10–80 oz/yd 2 , said mat being formed of fiberglass.
14. A covering according to claim 13 wherein said non-woven base layer and the pre-coat have weights of 8–12 oz/yd 2 and about 24 oz/yd 2 , respectively, said first and second polyvinyl chloride layers each having weights of about 45.5 oz/yd 2 , said mat being formed of fiberglass.
