Abstract
Process for obtaining regenerated cellulose products, characterized in that a compound of general formula is added to the viscous wing. Ro - (ch subscript 2 ch subscript 2 o) subscript n - r 1 (where r in an alkyl or aryl radical, n is equal to 1, 2,3 or 4 and r is hydrogen, or an alkyl or aryl radical ), soluble in an aqueous solution of 6% sodium hydroxide, in a proportion of at least 1% and soluble only in a proportion not greater than 0.5%, at room temperature, in the coagulation acid bath, which is used to spin the resulting viscose.
