| titleOfInvention | A kind of caprolactam hydrolytic polymerization fibres and spinning process thereof |
| abstract | The present invention relates to a kind of caprolactam hydrolytic polymerization fibres and spinning process thereof, polyamide 6 performed polymer is prepared by first low temperature, control oligomer in melt in advance, it is aided with binary acid end-blocking, terminal amino group content in reduction system simultaneously, then carries out ethylene glycol end-blocking, chain growth is carried out afterwards by the way of de-glycol ester exchanges, in products therefrom, extractable≤2wt%, cyclic dimer content≤0.3wt%；Then, after polycondensation reaction terminates, directly melt spinning shapes.Present invention process is simple, while improving the utilization rate of caprolactam, also reduces energy consumption, and obtained melt can direct melt spinning, it is easy to accomplish Large Copacity large-scale production, can be applicable to take the fields such as fiber, industrial yarns, engineering plastics. |
