| titleOfInvention | Improvements in the production and treatment of artificial filaments, yarns, films and like materials containing cellulose derivatives |
| abstract | Artificial filaments, threads, yarns, ribbons, films, and like materials containing organic derivatives of cellulose are brought into a plastic condition by treating them uniformly along their length with a medium comprising an aliphatic compound containing halogen and oxygen, and they are subjected to a stretching or shrinking operation. The halogen-oxygen compound may be contained in the coagulating bath when the materials are produced by a wet spinning process. The materials may be treated continuously with their production by dry or wet spinning processes, or they may be treated in a separate operation. Stretching may be restricted to the portion of the travelling materials which has been brought to a plastic state. The filaments may be treated while arranged in warp formation. The halogen-oxygen compound may contain more than one halogen or oxygen atom, and the oxygen is preferably present in a polar group such as a hydroxyl, ketonic, or ester group. Chloral hydrate, chloral alcoholate, chloretone, dichloracetone, chlorine derivatives of ethyl acetate, ethylene chlorhydrin, glycerine mono- and di-chlorhydrins, are examples of halogen-oxygen compounds which are used. Other solvents or softeners may be present e.g. acetic acid, acetone, the ethers, esters and ether-esters of olefine glycols, dioxane, methylene ethylene ether, ethyl lactate, diethyl tartrate, diacetone alcohol. The solvent or softener may be employed in solution in water, alcohols, ethers, hydrocarbons, or chlorinated hydrocarbons. The spinning solutions may contain the same solvent or softener as is used in the coagulation bath or subsequent treatment bath. Cellulose acetate in a mixture of chloral hydrate and dioxane may be spun into an aqueous solution containing chloral hydrate and dioxane. Specifications 277,089, 323,790, [both in Class 2 (ii)], 340,324, 340,436, 340,437, 378,858, and 405,275 are referred to. |
