Abstract: The invention pertains to the use of a multifilament yarn spinning process comprising individually washing each filament of a multifilament yarn and, if neutralized, individually neutralizing each filament of the multifilament yarn, for preventing yarn breakage during the spinning process, the spinning process comprising spinning of a polymer through a spinneret to obtain the multifilament yarn, washing the yarn, and optionally neutralizing and/or drying the yarn and winding the yarn onto a bobbin Preferably the yarn is washed with jet washers.
