Abstract

A textile floor covering consisting of a textile layer, to the carrier layer of which the pile has been applied, and a bottom of thermoplastic foam, wherein the textile layer is directly connected with a thermoplastic foamed sheeting of polymerizates as a bottom, the polymerizates being selected from a group consisting of ethylene polymerizate, ethylene vinylacetate copolymerizate, and a mixture of ethylene polymerizate and ethylene vinylacetate copolymerizate, the foamed sheeting having a thickness of between 1.5 and 10 mm and a density of 0.10 to 0.40 g/cm.sup.3, preferably from 0.15 to 0.20 g/cm.sup.3. A method for producing a textile floor covering consisting of a textile layer, to the carrier layer of which the pile has been applied, and a bottom of thermoplastic foam, wherein the textile layer is applied directly to a foamed sheeting of polymerizates, as defined above, by means of thermolaminating, welding, sewing or stitch-bonding.
