摘要

Spinneret for the production of elastane fibres by the wet spinning process has holes (3a -3k) arranged closely together in distinct areas (12a, 12b). These are separated by strips (13), with no holes, which are at least 2mm. in width. An Independent claim is included for a method for producing elastane fibres by spinning an elastane solution of concentration at least 25% using at least four spinnerets designed as described above in which the fibres from each area are cut off and subjected to further processing.
