Abstract

Ammoniacal copper solutions of cellulose, processes for making filaments from.-In the manufacture of artificial silk by the cuprammonium process, in which the thread is passed from the spinning funnel to a hardening bath comprising acid and salt solutions, deleterious after-effects of the hardening bath are prevented by subjecting the thread to a washing process either directly on coming out or during its winding on spools or reels, or during its collection in spinning boxes. The nature of the washing liquid is varied with the nature of the hardening liquid, but in general consists of water, or salt solutions, or weak alkaline solutions. The washing treatment may be carried out at raised temperatures. The liquid flowing out of the spinning funnel and containing small quantities of ammonia may be employed as the washing liquid.
