Abstract: 1327405 Floor covering BAYER AG 13 Oct 1970 [17 Oot 1969] 48558/70 Heading B2E A floor covering comprises a textile surface layer, e.g. needled felts, tuftings, pilefabrics, knitted fabrics or Raschel webbing and an underlay of non-foamed polyurethane formed from a polyhydroxy compound and a polyisocyanate used in an OH/NCO molar ratio of from 1:0.6 to 1:1.3. Suitable polyhydroxy compounds are polyethers of ethylene glycol, propylene glycol and/or butylene glycol having two or more terminal OH groups of average molecular weight of 300-5000 which may be reacted with tolylene-2,4 and -2,6-diisocyanate and mixtures thereof, the crude phosgenation product of the condensation product of aniline and formaldehyde, diphenyl methane-4,4'-diisocyanate and diphenylmethane diisocyanate modified with 5-10% wt. of carbodiimide. The textile may be of synthetic fibres (e.g. polyethylene glycol terephthalate, polyamide or polyacrylonitrile) or natural fibres such as cotton. The underlay may be applied directly to the textile or by transfer coating from a web.
