| Abstract: | Polyacrylonitrile fiber was treated with the mixture solution of acetic acid and hydrochloric acid in order to improve the extensibility.The effects of the reaction temperature and time and the mass fraction of acetic acid and hydrochloric acid on the tensile strength and elongation of polyacrylonitrile fiber were discussed by orthogonal experiments.The results showed that the elongation of polyacrylonitrile fiber could be 73.2% and the tensile strength up to 2.31 cN/dtex under the conditions as followed: 10% acetic acid and 0.08% hydrochloric acid by mas fraction,reaction temperature 150 ℃ and time 75 min. |
