    • Materials comprising cellulose esters are saponified by means of an alkaline agent in the presence of an organic base, or salt of such base, having pentavalent nitrogen, phosphorus, antimony, or arsenic, or tetravalent sulphur, and which contains a chain of at least four carbon atoms and is capable of being adsorbed by the materials. Examples of such bases or salts are dodecyltrimethylammonium bromide, octadecenyltrimethylammonium bromide, dodecylpyridinium sulphate, diethylbenzyl-dodecylammonium chloride, the addition product of dimethyl sulphate and naphthalene sulpho - N - b - oxyethyl - N - dimethyl - 1, 3-propylenediamine (obtained by reacting naphthalene-b -sulphochloride with N-b -oxyethyl-1-amino - 3 - dimethylaminopropane) p-methoxyphenylacetophenone - o - trimethylammonium bromide (obtained by brominating p-acetoxyphenylacetophenone in acetic acid and allowing a solution of the product in dioxane to stand with two molecular proportions of trimethylamine until the product is soluble in water), methylethylcetylsulphonium methosulphate, cetyltrimethylphosphonium iodide, trimethyldodecylarsonium hydroxide (obtained by the action of dodecyl bromide on trimethylarsine and reacting the product with moist silver oxide) and trimethylundecyl stibonium chloride (obtained by reaction of undecyl chloride and trimethyl stibine. The process is applicable in the superficial saponification of films; in the saponification of mixed fabrics from cellulose acetate artificial silk and regenerated artificial silk for the purpose of dyeing them in common by means of direct cotton dyestuffs for subsequent discharge printing; for grounding cellulose acetate fabrics with alkali naphthol or printing cellulose acetate fabrics with vat dyestuffs or mixtures of diazo-compounds and azo-compounds, wherein the printing paste must cause local saponification. The threads may be treated with resists, e.g. sodium cresol sulphonate, advantageously in the presence of a protective colloid. In examples: (1) a cellulose acetate fabric is saponified in the presence of dodecyltrimethylammonium bromide, and dyed with direct dyestuffs; (2) cellulose acetate fabric is saponified in the presence of para-ethoxyacetanilide-o -trimethylammonium bromide; (3) cellulose acetate fabric is saponified in presence of diethylbenzyl - dodecylammonium chloride; and (4) cellulose acetate filaments are treated during winding with a solution of trimethyldodecylammonium bromide and methyl glycol, spun with similar yarn prepared with olive oil, worked into a fabric, and dyed with direct dyestuffs.
