Embodiment
[0032] Embodiment: A spinning and winding joint manufacturing process of 24 ends / position multi-differential mixed fiber composite fibers in one step is carried out according to the following process steps:
[0033] ①. Material preparation: Put the sliced raw materials into the vibrating screening equipment for screening, screen out the powder and particles with inconsistent particle sizes, and obtain the sliced raw materials that meet the requirements, and then transport the sliced raw materials to the silo for standby;
[0034] ②, crystallization and drying: the slices in the silo are sent to the pre-crystallization bed for crystallization, and then the crystallized slices are transported to the slice drying tower for drying to remove the moisture in the slices;
[0035] ③ Melting and filtering: Send the dried slices into the extruder to heat and melt into a melt, and then transport the melt to a melt filter for filtration to remove impurities in the melt;
[0036] ④ M...
