Fremgangsmåte for fremstilling av cellulosefibre |
摘要 |
<p>The invention relates to a method of producing lyocell-type cellulose fibers by processing a spinnable solution of cellulose in an aqueous tertiary amine oxide according to the dry/wet-spinning process, which method is characterized in that a solution having a content of between 0.05% and 0.70% by mass, based on the mass of the solution, of cellulose with a molecular weight of at least 5x105 is used for spinning. The method of the invention allows the use of a spinnerette having more than 10,000 spinning holes for the spinning operation, which holes are arranged in such a manner that neighboring spinning holes are spaced maximally 3 mm apart and that the linear density of the spinning holes it at least 20.</p> |
