Self-twist spinning - ScienceDirect
2010-1-1 · Due to the zero-twist zones at every twist changeover, ST yarns contain points of weakness along the length. In the case of an in-phase yarn (see Fig. 14.25(a)), if the length of zero-twist zones is equal to or greater than the length of bridging fibres, then the force required to break the yarn is low. This confirms the importance of fibre ...
