Recyclable carpet floor covering

A recyclable carpet floor covering comprising a backing, a tied-in pile yarn and a back finish with or without a secondary backing adhered to the (primary) backing, wherein the pile yarn, the (primary) backing and a secondary backing comprise polyester fibers and the back finish for the (primary) backing and for adhering a secondary backing comprises a consolidating and adhering composition comprising a combination of

• 10-70% by weight of a water-soluble or -dispersible first polyester A, and
• 90-30% by weight of a water-insoluble second polyester B,
• wherein
• the water-soluble or -dispersible polyester A conforms to the formula I ##STR8## where R.sup.1 is on average 25-90 mol % o-, m- or p-phenylene, 10-25 mol % groups of the formulae II or III ##STR9## where R.sup.3 is o-, m- or p-phenylene or straight-chain or branched alkylene of 2-6, carbon atoms, and 0-50 mol % straight-chain or branched alkylene of 1-6, carbon atoms and/or cyclohexylene radicals,
• R.sup.2 is on average 50-100 mol % radicals of the formula IV ##STR10## where R.sup.4 is hydrogen or methyl and m is 1 or 2, 0-50 mol % alkylene radicals of 2-6 carbon atoms, and 0-20 mol % polyoxyalkylene radicals of the formula IV where R.sup.4 is hydrogen or methyl and m is a number corresponding to a number average molecular weight of the polyoxyalkylene radical of up to 2000,
• E is hydroxyl, alkoxy of 1-4 carbon atoms or the radical--O--R.sup.2 OH,
• M is hydrogen or a lithium, sodium or potassium atom or an ammonium group,
• n is such that the number average molecular weight, measured in a vapor pressure osmometer in dimethylformamide as the solvent, is from 1000 to 12,000, and
• the water-insoluble polyester B conforms to the formula V ##STR11## where R.sup.4 is on average 50-100 mol % o-, m- or p-phenylene, and 0-50 mol % straight-chain or branched alkylene of 1-6, carbon atoms and/or cyclohexylene radicals,
• R.sup.5 is on average 30-100 mol % radicals of the formula VI ##STR12## where R.sup.4 is hydrogen or methyl and m is 1 or 2, and 0-70 mol % alkylene radicals of 2-6 carbon atoms and/or radicals of the formula VII ##STR13## and 0-20 mol % of polyoxyalkylene radicals of the formula IV where R.sup.4 is hydrogen or methyl and m is a number corresponding to a number average molecular weight of the polyoxyalkylene radical of up to 2000,
• E is hydroxyl, alkoxy of 1-4 carbon atoms or the radical--O--R.sup.2 --OH, and
• p is such that the second polyester has a melt index of 110.degree.-130.degree. C.
