Abstract

177,778. Gibbons, W. A., and Ritter, H. W. March 31, 1921, [Convention date]. Fabrics with multiple superposed coatings; single coatings; compound fabrics and sheet materials.-Artificial leather &c. is made by mixing a plastic material such as a rubber mixing or nitro-cellulose composition with a filler holding a liquid' or gaseous pore-producing agent, sheeting the mix, expelling all or part of the poreproducing agent, and setting the sheet in a pliable, permeable condition. The. sheet is preferably made on or applied to a fabric backing. Several examples are given, of which the following is typical : 100 parts of pale crepe, 10 parts of zinc oxide, 4 parts of p-toluidine, 2 parts of sulphur, 4 parts of dibutyldixanthic-disulphide. are mixed with sufficient solvent naptha to produce a pasty mass. 100 parts of cotton fibre saturated with water are mixed with this composition. The mass is sheeted or calendered on to a fabric which has been thinly coated with rubber. The sheet may be embossed, varnished, &c., and is then heated to expel the water and so form minute pores, and to vulcanize the composition, a temperature of 200‹ F. for 10-30 minutes being sufficient. The accelerator may be added more safely at a later stage of the mixing. Other fibres may replace the cotton, and other non-solvent liquids the water. Dry fibres or substances such as magnesium carbonate may be employed in some instances, the air entrapped in their interstices being sufficient on heating to produce pores. In such cases, the amount of air may be increased by blowing it into the mixture. A suitable nitro-cellulose composition consists of pyroxylin 12 gm., castor oil 12 gm., cotton fabrics (wet) 10 gm., amyl acetate 200 cc., benzol 125 cc., and carbon black 1 gm. The mixture is spread on fabric, and dried at about 100‹ C. between coats. The invention also includes blended nitro-cellulose and india-rubber composition permeable sheets, and sheets of superposed layers of nitro-cellulose and india-rubber compositions.
