Preparation of Cuprammonium Biodegradable Rayon Fibers
Consequently, the viscose process is a multivariate system. Dissolving cellulose (i.e. a pulp with low lignin and hemicelluloses content) is mainly used for production of viscose and spinning of viscose staple fibres.... A process for the production of rayon fibers. The viscose solution is spun into a spinbath which is acidic in character but has no zinc salt like conventional baths. The spin bath contains sulphuric acid, aluminum sulphate and sodium sulphate. The spinning is at temperatures of 35°-60° C. Usual stretching and post spinning operations are
