Abstract
Improvement in the method for the manufacture of fibers, artificial films and similar viscose products in which the products formed are first subjected in continuous process after coagulation to a treatment to decompose the cellulose xanthogenate present in the products and then to the products. Common after-treatments including desulphurisation and bleaching performed in two-phase decomposition namely in which the molecular ratio of xanthogenate in the products has dropped to less than a value of about 0 02 and after these products have been liberated from the liquid bath for example by washing in the second phase with oxidizing agents until the ratio of xanthogenate in the products has dropped to less than 0 003, preferably below 0 002 as described in spanish patent no. 187,792, consisting of the improvement in which the products after removing them from the bath liquid of the first to phase they are impregnated first with acid and later in the second phase of the decomposition with an alkaline solution of a salt of the chlorous acid whose ph is always greater than 7 and less than 12.
