Abstract: A process is disclosed for preparing an absorbing mop material comprising a substratum of non-woven fibres and a flexible, porous, polymeric binder. The process comprises preparing a non-woven web of textile fibres, consisting essentially of a cellulosic material, preparing an aqueous dispersion containing a thermocoagulable polymer and a coagulating agent, adding to the aqueous dispersion a liquid expanding agent having a boiling point of 30.degree. C. to 80.degree. C., impregnating the web with the aqueous dispersion to which the expanding agent has been added, subjecting the impregnated web to a heat treatment at 40.degree. C. to 90.degree. C., washing the web with water, and subjecting the web to a further heat treatment at a temperature equal to or greater than 100.degree. C.
