Process for working up molten cellulose derivatives into threads and other shaped articles

A cellulose derivative having a content of water between that which it would normally have after being exposed to the open air and that of the saturation point observed on melting is brought into the molten state and worked up into threads or other shaped structures. On exposure to the open air, cellulose triacetate takes up 0.1-0.3 per cent of water; a partially hydrolysed cellulose acetate may take up about 1.5 per cent. The saturation point observed on melting is that content of water above which evaporation of the water with foaming occurs when the cellulose derivative is melted. The presence of water in the cellulose derivative considerably reduces the melting-point and thus the temperature of the working-up process. The upper limit of the moisture content is usually not more than 10 per cent. For cellulose triacetate it is about 6 per cent and for a hydrolysed cellulose acetate it may be 8-9 per cent. The cellulose derivative may be dried to the desired moisture content during the ...

Improvements in the manufacture of films, sheets and the like containing cellulose derivatives

When coagulating cellulose ester and ether films, sheets, foils &c., transparent, smooth and easily detachable products are obtained by employing a coagulation bath with which a solvent or latent solvent of the film-forming solution has only a limited miscibility, and removing the film from the bath whilst it still contains a substantial proportion of such solvent or latent solvent. The liquid used for the preparation of the film forming solution may be a solvent, or a mixture of solvents, or a solvent mixture, although true solvents are preferred. If acetone or other water-miscible solvents are employed, the coagulation bath conveniently comprises a hydrocarbon; if a halogenated hydrocarbon or other hydrophobe solvent is used, an aqueous coagulation bath may be employed. The miscibility of the solvent with the coagulation bath may be still further reduced by dissolving in the latter salts, sugars &c., according to Specification 343,062, or by adding to the bath a proportion of the solvent ...
