Patent GB-1121651-A (GB)
Title: Process for the coagulation of emulsions within a porous substrate
IPC: D04H1/4258
Filed: 1964-04-30
Abstract: An emulsion of an organic material of high molecular weight is coagulated within a porous substrate impregnated with the emulsion by subjecting the substrate to the action of steam containing, as a vapour, a material which reduces the stability of the emulsion. The substrate may be a web of fibres, a woven or non-woven fabric or paper.  The emulsion may be of natural rubber, natural or synthetic wax, a polymer of isoprene or chloroprene, a copolymer of butadiene with acrylonitrile, styrene or acrylic ester, a polymer or copolymer of an acrylate, vinyl chloride, vinyl acetate or vinylidene chloride, a silicone resin or a mixture of these.  It may also contain an additive such as a stabilizing or vulcanizing agent, an antioxidant, a pigment, a thermosetting resin or a catalyst.  The material that reduces the stability may be an acid, e.g. formic, an alkali, e.g. ammonia, or an alcohol, e.g. methyl or ethyl alcohol.  The emulsion may also contain a material that reduces its stability, but does not coagulate it at ambient temperatures, e.g. ammonium chloride or polyvinyl methyl ether.  Non-woven fabrics can be made by impregnating a web of fibres with an emulsion of natural or synthetic rubber or resin, coagulating as above, washing to remove auxiliary agents from the emulsion not wanted in the finished fabric and drying.  In the Example a web of flax is impregnated with an emulsion of butadiene-methacrylate copolymer, polyvinyl methyl ether, ammonium chloride and water.  The impregnated web is then passed over a boiling mixture of water, formic acid and ethyl alcohol, squeezed, rinsed in water containing sodium carbonate, squeezed again and dried.  Other applications are to the impregnation of yarns with rubber, the finishing of textile fabrics and dyeing by binding pigments to fabrics by acrylic emulsions.
