With the idyllic spinning wheel from the Grimm fairy tales, the modern production of yarns and twists does not have much to do.
Fully automatic bobbins are changed and thread breaks are connected, because everything has to be right. This also applies to the spindle drive of twisting and spinning machines. Thus, the coefficient of friction on the one hand must be low in order to allow a defined slip on the drive, on the other hand, one needs a high coefficient of friction in order to ensure a good entrainment. Furthermore, the antistatic band coating should not attract the omnipresent fiber fly.
