Abstract

Process for forming a microporous polyurethane body backed with fibrous sheet material in which process a body of an emulsion is prepared of which the discontinuous phase is a volatile non-solvent liquid and the continuous phase is a liquid polymeric material which sets through reaction to solid condition, the liquid emulsion is formed as a layer and reacted under conditions preserving the uniformity of the emulsion to pressure flowable stage having a pre-gel structure which will prevent sinking in of a fibrous sheet material and fibrous sheet material is laid on the layer and pressed into engagement with it to cause the emulsion to adhere to the fibrous sheet and to conform to irregularities. The reaction is continued to solidify the emulsion in firmly adherent relation to the fibrous sheet and the volatile liquid is removed from the solidified emulsion.
