Title: Manufacture of artificial materials
IPC: C08L1/22

Abstract: Cellulose xanthofatty acid, or a salt thereof, prepared by the process described in Specification 231,800, is used for the manufacture of articles or products such as coatings, finishes, sizes, artificial leather, cements, thickening-agents for pigments in textile printing, plastic compositions, films, and artificial threads.  The cellulose derivative is used in the form of a solution in water or an aqueous solution of a volatile inorganic or organic base such as ammonia, a primary, secondary, or testing amine of the aliphatic or aromatic series, a poly-amine, a quaternary base of acyclic or cyclic structure, or a member of the guanidine, pyridine and quinoline group; and with the solution may be mixed other colloids and also softening-agents such as albuminous substances, gelatine, amyloid, starch and the like, dextrin, gums, tragasol, glycerine, di-glycerine, poly-glycerine, glycols, sugars, syrups, soaps, fats, oils, and ammonium and alkali-metal compounds of fatty sulphonic acids, such as turkey-red oil.  The solution may be converted into the desired article or product by drying at atmospheric or reduced pressure, in the cold or with heating. According to the examples, films are manufactured by applying a solution of a cellulose xanthofatty acid in water in an aqueous solution of aniline, ammonia or pyridine to a suitable support and, after drying, stripping therefrom, followed, if necessary, by a steaming or heating in order to reduce the tendency to swell in presence of water; textile fabrics of vegetable or animal origin are finished by the application solutions similar to those used in the first example and to which are added a filling material such as zinc white, china clay or talc, or a softening-agent such as turkey-red oil or a drying or non-drying oil or a soap, or another colloid such as a solution of starch, the coated fabric being subsequently dried and optionally heated or steamed, or washed with an aqueous solution of aniline or toluidine, and, after finishing, satined, calendered, patterned or glazed; textile fabrics are printed with a solution of the cellulose xanthofatty acid such as is used for the manufacture of films and to which has been added a dyestuff lake, mica, zinc white, or lithopone, soot, or powdered aluminium, and the printed material is subsequently dried, and is optionally heated or steamed, or is tested with a solution of aniline or toluidine; book cloth is made by applying to a fabric such as calico, one or more coatings of the solutions of the cellulose xanthofatty acid as used in the previous examples and to which may be added zinc white, china clay, finely-divided cellulose fibre, soot, or a lake, mica or a dyestuff, the coated material being, if desired, dried and calendered after each coating, and finally heated, steamed or treated with an aqueous solution of aniline or toluidine; a size for paper is prepared by mixing the solutions used in the first example, with the half-stuff, and then precipitating in the solid form with aluminium sulphate; artificial threads are made by squirting the solutions, the issuing thread being dried in the air, heated or steamed or treated with an aqueous solution of aniline or toluidine, and finally dried.ALSO:Cellulose xantha-fatty acid, or a salt thereof, prepared by the process described in Specification 231,800, is used for the manufacture of finishes, sizes, and cements.  The cellulose derivative is used in the form of a solution in water or an aqueous solution of a volatile inorganic or organic base such as ammonia, a primary, secondary, or tertiary amine of the aliphatic or aromatic series, a polyamine, a quaternary base of acyclic or cyclic structure, or a member of the guanidine, pyridine and quinoline group; and with the solution may be mixed other colloids and also softening-agents such as albuminous substances, gelatine, amyloid, starch and the like, dextrin, gums, tragasol, glycerine, di-glycerine, poly-glycerine, glycols, sugars, syrups, soaps, fats, oils, and ammonium and alkali-metal compounds of fatty sulphonic acids, such as turkey-red oil.  The solution may be converted into the desired article or product by drying at atmospheric or reduced pressure, in the cold or with heating. According to the examples, textile fabrics of vegetable or animal origin are finished by the application of a solution of a cellulose xantho-fatty acid in water or in an aqueous soltuion of aniline, ammonia, or pyridine, and to which is added a filling material such as zinc white, china clay, or talc, or a softening-agent such as turkey-red oil or a drying or non-drying oil or a soap, or another colloid such as a solution of starch, the coated fabric being subsequently dried and potionally heated or steamed, or washed with an aqueous solution of aniline or toluidine, and, after finishing, satined, calendered, patterned, or glazed; textile fabrics are printed with a solution of the cellulose xantho-fatty acid such as is used for the manufacture of films and to which has been added a dyestuff lake, mica, zinc white or lithopone, soot, or powdered aluminium, and the printed material is subsequently dried, and is optionally heated or steamed, or is treated with a solution of aniline or toluidine; book cloth is made by applying to a fabric such as calico, one or more coatings of the solutions of the cellulose xanthofatty acid is used in the previous examples and to which may be added zinc white, china clay, finely divided cellulose fibre, soot, or lake, mica or a dyestuff, the coated material being, if desired, dried and calendered after each coating, and finally heated or steamed or treated with an aqueous solution of aniline or toluidine; a size for paper is prepared by mixing the solutions used in the first example, with the half-stuff, and then precipitating in the solid form with aluminium sulphate.
