ABSTRACT OF THE DISCLOSURE A lubricant for organic fibers and process for preparing it are provided. The lubricant contains (a) an aqueous emulsion of a diorgano- polysiloxane having an average viscosity of at least 20,000 cSt at 25°C, and component (b) in which (b) is selected from the class consisting of (i) a paraffin wax, (ii) a perfluoropolymer in which some of the fluoro groups may be substituted with chlorine atoms and mixtures thereof. The aqueous emulsion is obtained from the aqueous emulsion polymerization of the diorganopolysiloxane in the presence of component (b). The composition is applied as a lubricant to organic fibres to improve their slip proper- ties. This composition, containing no organic liquids, does not involve the risk of fire, explosion, unpleasant smells and health hazards. The lubricant is easily prepared and is a stable dispersion. It imparts in- creased lubricity to the treated fibres so that they may be sewn and pro- cessed more easily.
