Abstract
A secondary backing for surface coverings is disclosed which comprises at least one thermoplastic material optionally having polymeric microspheres dispersed therein. A textile substrate comprising a primary backing with textile fibers extending upwardly from the backing and forming a surface and the above-described secondary backing attached thereto is also described. Methods of making the textile substrate and the secondary backing which can be foam or hardback are also described. Also described is a resilient surface covering, such as vinyl flooring, using the secondary backing of the present invention in one or more layers.
Claims22
A textile substrate comprising a primary backing with textile fibers extending upwardly from the backing and forming a surface:
- and a secondary backing affixed to the bottom surface of the primary backing wherein said secondary backing comprises at least one thermoplastic material having polymeric microspheres dispersed therein, wherein said thermoplastic material comprises a polymer or copolymer of a vinyl compound, and at least one plasticizer.
A surface covering comprising a primary backing and overlying and adhered to said primary backing is a secondary backing comprising at least one thermoplastic material having polymeric microspheres dispersed therein and at least one activated blowing agent, wherein said secondary backing is casted on said primary backing, and wherein said thermoplastic material comprises a polymer or copolymer of a vinyl compound and at least one plasticizer.
A surface covering comprising a primary backing;
- at least one adhesive or polymeric precoat layer located and affixed to the primary backing;
- optionally at least one intermediate backing layer located beneath and affixed to the adhesive or polymeric pre-coat layer;
- optionally at least one reinforcement material layer or stabilizer layer located and affixed beneath the adhesive or polymeric pre-coat layer or intermediate backing layer;
- and a secondary backing comprising at least one thermoplastic material located and affixed to either the adhesive or polymeric pre-coat layer or one of the optional layers;
- and
- wherein polymeric microspheres are dispersed in at least one of the layers except the primary backing, wherein said thermoplastic material comprises a polymer or copolymer of a vinyl compound, and at least one plasticizer.
