Abstract (en)

[origin: DE19829063A1] The invention relates to a method for producing elastane fibers having a titer of at least 2,500 dtex using a wet spinning method and to the coarse titer elastane fibers having a large cross section and low residual solvent content produced according to said method. The method comprises the following steps: spinning a viscosity stable elastane solution of up to 35 g/% in a spinning bath, washing and optionally stretching, drying by contact heating, fixing, preparing and winding the fibers, wherein after leaving the spinning bath the filaments are guided around a deflection roller located slightly above the spinning bath liquid and wherein individual spinning titer corresponds to no more than 1 % of the value of the final titer, drawing ranges between 0.5 and 50, contact heating temperature is at least 220 DEG C and length of contact of the elastane fibers is at least 2 seconds.
