Abstract
Artificial filaments obtained by extruding a solution of a vegetable globulin or casein into an acidified saline coagulating bath are given an increase in strength by stretching the coagulated unhardened filaments in presence of a saline solution having no swelling effect on them and at a temperature not exceeding 40 DEG C., and then subjecting them in the stretched condition to the action of a hot saline solution at a temperature above 40 DEG C., which also has no swelling effect on the stretched filaments, until they have substantially lost their contractility. The freshly coagulated filaments may be stretched in presence of the acidified saline solution of the coagulating bath and, if desired, they may be stretched in air in presence of the liquid that adheres to them when they leave the coagulating or other suitable saline bath. The hot saline solution may, if desired, contain a salt the same as that in the solution in presence of which they were stretched or a salt that is present in a subsequent hardening solution, and it may include ingredients which assist the hardening of the filament. The process of stretching and liquid treatment may be repeated as many times as may be practicable. In an example, a matured alkaline solution of peanut globulin is spun into an aqueous coagulating bath at 28 DEG C. containing sulphuric acid and sodium sulphate. The filaments so produced are stretched as they emerge from the bath and are wound upon a swift, whereupon they are sprayed with a solution of sodium sulphate at 45 DEG C.
