Abstract

8708. Lilienfeld, L. April 21. Finishes for fabrics &c.-Stable products are obtained by treating viscose or salts &c. thereof with an oxidizing-agent, such as potassium permanganate or manganate, and precipitating the product with a suitable precipitant, for example an acid, a salt, a mixture of acid and salt, alcohol, &c. The precipitate is freed from adherent manganese compounds by treatment with, say, sodium bisulphite, sulphurous acid, or sodium nitrite. The products are soluble in alkalis, ammonia, or water. The soluble products are applicable for sizing, finishing, sizing paper, &c. They may be used alone or mixed with albumen, glue, carbohydrates, &c.
