摘要：The invention relates to a method of producing lyocell-type cellulose fibers byprocessing a spinnable solution of cellulose in an aqueous tertiary amine oxide accordingto the dry/wet-spinning process, which method is characterized in that a solution having acontent of between 0.05% and 0.70% by mass, based on the mass of the solution, ofcellulose with a molecular weight of at least 5×10is used for spinning. The method of theinvention allows the use of a spinnerette having more than 10,000 spinning holes for thespinning operation, which holes are arranged in such a manner that neighboring spinningholes are spaced maximally 3 mm apart and that the linear density of the spinning holesit at least 20.
