Abstract

289,942. Carpmael, W., (I. G. Farbenindustrie Akt.-Ges.). Feb. 2, 1927. Ammoniacal-copper collulose solutions, processes for making filaments from.-The precipitating-bath consists of water to which free carbonic acid or a bicarbonate has been added. By the use of such a bath, the threads obtained have an increased strength and elasticity, while the deposition of copper salts on the walls of spinning funnel it the stretch-spinning method is adopted, are obviated. Specifications 8711/08, 15448/08, and 15449/08 are referred to.
