| Abstract: |
| In order to get high strength and high modulus PA6 fibers，by using CaCl2 as complexing agent，the ultra－high molecular weight PA6 fiber(UHMW PA6）was prepared by gel spinning techno－logy，and the effect of coagulation bath temperature on the structure and properties of UHMW PA6 fiber was studied.The experimental results showed that，when the coagulation bath temperature was low，the PA6 molecules were in better orientation，the birefringence of fiber was higher， the content ofα－crystal was higher，and the strength and modulus of fiber were better.It was found that the surface of the fiber was smooth when the coagulation bath temperature was in the temperature range of 4～8 ℃.In order to achieve high mechanical properties of fiber and minimize the influence of ambient room temperature on the process，the optimum coagulation bath temperature was 8 ℃. |
