Abstract

This invention relates to a new washing apparatus for the continuous production of elastane filaments which are produced by a wet-spinning process, which essentially consists of a stripping unit (10) and a washing unit (11) which are disposed in steps above the precipitation bath (1) of a wet-spinning device.
