Abstract

Abstract

Abstract: The influence of coagulation variables on diffusion during wet-spinning was investigated by measuring the remaining weight of the samples. The transverse structure of the coagulated samples was also studied. It is found that coagulation slows down with increasing dimethyl sulforide (DMSO) concentration while the transverse structure of the coagulated sample becomes finer. The coagulation speed is faster and the transverse structure is finer at 50℃ than at 30℃ and 80℃. The additive makes coagulation slower, however, some voids are generated across the coagulated samples.
