In the process of producing PAN precursor used in carbon fiber, applying orthogonal experiment method and a dry-wet spinning technology, the main systematical study are the influence of coagulation bath, jet stretch, pre-draft and water-bath draft on degree of orientation. Results show that under applying dry-wet spinning technology, in smaller jet velocity, and to give fiber appropriate pre-draft ratio and high water-bath draft ratio, degree of orientation is higher, and high fiber strength also can be obtained.
