摘要：

Polyacrylonitrile (PAN) fibers have been gel spun from pregelled PAN spinning solution. The pregelled solution had network structure with elevated spinnability, the as-spun fiber from which had more circular cross-section and reduced skin-core difference. Drawing was more effective in inducing the segmental orientation and crystallization in gel-spun fiber than in dry-wet spun fiber. The mechanical properties of the gel-spun fiber were better than those of the dry-wet spun fiber after multi-stage drawing. POLYM. ENG. SCI., 50:12901294, 2010.
