Abstract

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.
