Title: Improvements in or relating to the production of cellulose derivatives and materials made thereof
IPC: C08B15/06
Filed: 1939-01-26
Abstract: 524,292. Cellulose derivatives ; dyeing processes. DREYFUS, H. Jan. 26, 1939, No. 2683. [Classes 2 (ii) and 15 (ii)] Cellulose derivatives containing nitrogen are obtained by subjecting cellulose derivatives which contain aryl-sulphonyl radicles to the action of compounds containing at least two basic nitrogen atoms which are separated by a chain of at least 3 atoms. Cellulose derivatives which contain aryl-sulphonyl radicles attached directly to carbon atoms of the cellulose nucleus may be treated, or compounds in which the aryl-sulphonyl radicles are attached to groups which themselves are attached to the cellulose nucleus, may be treated. The aryl sulphonyl derivatives may contain other organic radicles, e.g., acetyl, propionyl, lactyl, oxalyl, ethyl, propyl. hydroxyethyl, or carboxyethyl. The cellulose derivatives may be treated in fibrous, filamentary, or other solid form or in solution. Nitrogen containing reagents which may be used include trimethylene diamine, tetra-methylene diamine, ##<SP>1</SP>- diaminodiethyl ether, di-ethylene-triamine, xylylene diamines, #-oxy-trimethylene diamine, and #-chlortrimethylene diamine. Secondary amines may be used. Cellulose or a cellulose organic compound containing free hydroxyl groups may be treated with p-toluene salphonyl chloride in benzine and in presence of an alkali, e.g., pyridine. Halides of benzene sulphonic acid or of #-naphthyl sulphonic acid may be used. Cotton fibres, regenerated cellulose, or cellulose derivative filaments or fibres may be treated with the aryl sulphonating agents and then with the nitrogen-containing compounds with retention of the fibrous form. Fabrics, yarns, or films, may be treated. Arylsulphonyl derivatives may be treated with the nitrogen-containing compound while they are dissolved in dioxane, pyridine, benzyl alcohol, or the nitrogen-containing compound itself. The reaction may be effected at room temperature or with heating in open or closed vessels. Cellulose derivatives containing nitrogen and cellulose derivatives containing aryl sulphonyl groups as well as nitrogen may be obtained. They may be of but slight solubility in the usual organic solvents and may have good affinity for acid dyes. Filamentary materials after treatment mav have increased resistance to ironing and increased tenacity. In an example, cellulose acetate yarn containing dryspun and stretched filaments is immersed in a benzine solution of p-toluene sulphonyl chloride. It is then immersed in a benzine solution of trimethylene diamine. The yarn has a good affinity for acid dyes. In another example, a yarn having a basis of hydroxy-ethyl cellulose acetate is treated in a similar manner. In another example, cellulose p-toluene sulphonate is dissolved in a mixture of dioxane and ethyl alcohol and dry spun. The filaments obtained are immersed in a solution of trimethylene diamine in benzine.
