摘要

There is disclosed an apparatus for spinning of polyurethane elastic filaments, which includes an improved means for application of a finishing agent and/or an improved means for false twisting. Each of the improved means has a groove through which a polyurethane elastic filament is allowed to pass, at which time a finishing agent is applied to the passing filament before its contact with any solid face of the apparatus.
