| abstract | 136,568. Gillet et Fils, (Assignees of Schwartz, C.). Dec. 13, 1918, [Convention date]. Inkless printing by chemical reaction; resist printing; printing with special materials.-Fabrics composed of vegetable fibres are treated to impart to them the character of wool by impregnation with a solution of cellulose of any origin in nitric acid, preferably at a concentration of not less than 65 per cent, and by washing the treated fibres with water to precipitate upon them slightly nitrated cellulose. Parts only of the fabrics may be treated either by printing with the cellulose solution at the desired parts, or by printing with a resist, such as kaolin, at the parts not to be treated and subsequent impregnation with the cellulose solution, the precipitation being produced by washing in each case. Treated fibres may be denitrated to increase the wool-like effect. The treatment is preferably effected at a temperature of 12 to 30‹ C., but the reaction takes place at 0‹ C.. the solution being more viscous however. The cellulose used in making the solution may be wood pulp or cotton waste, mercerized or not. Three examples of solution for treating fabrics of American cotton and one example for fabrics of Egyptian cotton are given. |
