Abstract:
The invention pertains cushioned vinyl floor coverings. For the production of cushioned vinyl floor coverings non-woven carriers made from glass fibers are currently used. However, handling of floor coverings with glass fiber carriers is quite difficult especially when the covering is laid on stairs or sharp edges. According to the present invention a solution to overcome the disadvantages of the prior art is a cushioned vinyl floor covering comprising a nonwoven carrier that is made from different polymers. The different polymers exist either in separate filaments or together in one filament.
