  • the spinning melt Due to the narrow range between the melting temperature and the decomposition temperature of nylon 66, and the presence of adipoyl structure in the nylon 66 polymer macromolecule, the spinning melt is prone to gelation in the molten state, which makes the melt pipe gradually smaller.

Therefore, before the winding, the fiber must be oiled to the wet, the oil is insufficient, the static electricity is easily generated during the stretching, and the filament is formed, so that the stretching cannot be smoothly performed; if the oil is too high, the fiber is too smooth, and the "collapse" is easily caused.
