Abstract
In the manufacture of artificial silk from ammoniacal copper oxide cellulose solutions, coagulation of the filaments is effected by water at a low temperature to such an extent that solidification of the filaments is incomplete, thereafter the filaments are led out of the spinning-apparatus, and treated, as for instance in a channel or bath, with water at a higher temperature in order to complete the solidification process. By operating in this manner, the formation of deposits on the walls of the spinning-apparatus likely to cause rupture of the filaments, is obviated. In an example, the first bath has a temperature of 20 DEG C., and the second bath of 50 DEG C. In the second bath, alkalies or salts may be added. The process is stated to be applicable to the spinning of solutions of cellulose esters or ethers, such as acetylcellulose or ethyl cellulose.
