Abstract

Process for manufacturing yarns, fibers, films, sheets and similar products from viscose in which a viscose is spun in baths containing a preferably sulfuric acid; characterized in that it starts from a viscose that contains in solution more than 0 1% by weight of one or more compounds of the formula; R1 - N- R2 R1 -N- R3 (d) where R1 is a cycloaliphatic or heterocyclic aliphatic group and R2 R3 are alkylene oxide chains represented by (Cn H2n O)xH where x and n may be different for R2 and R3 but x is not less than 4 in the case of R2 nor less than 1 in the case of R3 and both R2 as R3 may consist of different alkylene oxides and because said viscose is spun in a spinning bath containing more than 3% by weight of a zinc salt and in the acid concentration has been adjusted so that the ratio between the acidity of the bath and the alkali contained in the viscose ranges between 1 3 and 0 8; after which the obtained threads are wound.
