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.

Apparatus and a process for washing continuously wet-spun elastane

The invention relates to a process for preparing multifilament, wet-spun elastane threads with increased spinning output, which is achieved by largely removing entrained water from the filaments after leaving the spinning bath and then fixing the threads on at least two rollers at a temperature of at least 200.degree. C. for at least 3 seconds.

Process for preparing multifilament, wet-spun elastane threads

The invention relates to a process for adjusting the viscosity of highly concentrated elastane solutions by reaction of the solution with secondary aromatic amines in order to produce spinning solutions for the dry or wet spinning of elastane fibres.
