Abstract

For the production of threads, films, tubes, hollow bodies, &c., from cellulose acetates and other cellulose esters of aliphatic acids, there are employed solutions of the cellulose esters in organic acids, and coagulation baths consisting of strong solutions of strong acids. In examples, filaments are obtained by extruding solutions in acetic acid of secondary or primary cellulose acetates or a solution in formic acid of a cellulose acetate prepared without loss of the fibrous structure of the original cellulose, into 45 per cent sulphuric acid, and 45 per cent sulphuric acid containing an addition of sodium acetate, and 60 per cent sulphuric acid containing formaldehyde. The strong acid produces swelling of the coagulated product, and it may also saponify the cellulose ester wholly or partly. The products particularly if subjected to strong tension during production, are resistant to water, strong, ductile, and exhibit a low loss of strength on moistening with water. To the coagulation baths may be added inorganic or organic salts, alcohols and aldehydes. Reference has been directed by the Comptroller to Specifications 323,790, 324,662, 334,838, and 334,853, [all in Class 2 (ii), Cellulose &c.].
