Abstract

A solution of starch and starchy materials in sulphuric acid, to be used in the preparation of or as an addition to the setting-bath employed in the manufacture of artificial filaments, films, &c. from viscose, is prepared by mixing starch, &c., with water or dilute sulphuric acid, and adding thereto, while stirring, a quantity of concentrated sulphuric acid.ALSO:A solution of starch and starchy materials in sulphuric acid is prepared by mixing starch, &c. in a finely divided condition with water or with sulphuric acid of such dilution, and in either case at such moderate temperature that no gelatinization of the starch takes place, and then adding, while stirring a quantity of concentrated sulphuric acid. The solution may be used for the preparation of or as an addition to the setting-bath employed in the manufacture of artificial filaments, films, &c. from viscose.
