Abstract (en)
The object of the present invention is a method for producing hydrophobic polymer fiber filaments, the method comprising the following steps forming a melt from a hydrophobic polymer, melt-spinning the polymer to form filaments, applying a spin finish to the filaments, and optionally crimping and cutting the filaments into staple fibers. According to the invention, the method includes a step of subjecting the filament to at least one surface treatment step, preferably using a corona discharge or plasma treatment to increase the surface free energy thereof. An object of the invention is also an apparatus or production line for carrying out the method. <IMAGE>
