effect of coagulation bath conditions on cross section and skin-core structure of pan nascent fibers during wet-spinning
凝固浴条件对湿纺PAN初生纤维截面形状和皮芯结构的影响
Compared with the fibers produced by dry-wet spinning, the fibers from the not-pre-gelled gel spinning had more compact structure and fewer pores inside the fiber. The skin-core difference between the two types of fibers was, however, not pronounced.
与传统的干湿法纺丝相比,由未预凝胶化凝胶纺丝制得的初生纤维结构比较致密,孔洞较少,但是两者的皮芯结构差异并无明显区别。
