Abstract

Método de fabricar fibras artificiales a partir de viscosa, caracterizado pro la combinación de operaciones de expulsar a través de orificios viscosa que tiene una relación de celulosa a hidróxido sódico de, al menos, 1:1, dentro de un medio coagulante acuoso que no es un medio regenerante de al celulosa y que contiene desde 5 a 30% en peso de sulfato sódico y al menos 3% de ácido bórico, teniendo dicho baño en pH de desde 3 a 7, retirar del baño los filamentos contínuos de xantato de celulosa así obtenidos, y estirar los filamentos desde 50 a aproximadamente 200%.Method of manufacturing artificial fibers from viscose, characterized by the combination of operations of expelling through holes viscose having a cellulose to sodium hydroxide ratio of at least 1: 1, within an aqueous coagulant medium that is not a regenerating medium of cellulose and containing from 5 to 30% by weight of sodium sulfate and at least 3% of boric acid, said bath having a pH of from 3 to 7, remove the continuous filaments of cellulose xanthate from the bath as well obtained, and stretching the filaments from 50 to about 200%.
