Fabrication method of nylon 6 fiber by ultrafast spinning

摘要

After cooling the discharged nylon 6 yarn, the yarn is hot-rolled at the first godet roller at 100 to 140C and then heated and fixed at a second godet roller having a temperature higher than the crystallization initiation temperature and lower than the melting temperature to 400 to 6500 m / Min. /RTI ;The nylon 6 fibers prepared according to the present invention can be produced with excellent crystallinity and excellent spinning workability due to crystallization.
