Abstract

The invention relates to a spinning head (8) for spinning a spinning solutio n, having a tubular, thin walled spinning capillary (7) with an outlet (94). A mixture consisting of, for instance, cellulose, tertiary amine oxide and wat er is used as spinning solution. In order to reduce the tendency to fibrillatio n of the fibers spun by the spinning head and to enhance loop efficiency, the spinning capillary (7) is directly heated in the vicinity of the cross secti on of the outlet (94). By implementing this simple measure, tendency to fibrillation can be reduced and loop efficiency can be increased.
