Abstract: 796,207. Coated fabrics. KIMBERLYCLARK CORPORATION. May 2, 1956 [May 3, 1955; April 24, 1956], No. 13599/56. Drawings to Specification. Class 140. A coated fabric comprises a sheet of selfsustaining material, a film of cohesive rubber on one side and a coating of silica interposd between the base sheet and the film. The base sheet may be glassine or regenerated cellulose foil, cellulose acetate, polyesters, polyamides and other non-porous or porous sheets. The silica may be applied as a dispersion containing a wetting agent-a monosodium salt of sulphated methyl oleate, alkyl aryl polyether alcohols and alkyl aryl sulphonate salts are specified. If desired, the silica dispersion may be thickened by, e.g. sodium alginate. After being coated with the silica, the base is dried and coated with a dispersion of cohesive rubber or latex. If desired, two complementary sheets may be used, one carrying the silica coating and the other the rubber coating, this latter sheet being silica-coated or not as desired. The complementary sheet principle may be applied to opposite sides of a single sheet, so that one side coated with silica may be cohesively attached to the other side coated with rubber. The coatings in this case may be in stripes or staggered or offset patterns to prevent sticking when piled or in the roll. In an example, a ,glassine sheet is coated with a dispersion of colloidal silica containing sodium alginate and an alkyl aryl polyether alcohol, dried and then coated with a dispersion of natural rubber containing an antioxidant, an alkyl aryl polyether alcohol and ammonia.
