Abstract―The preparation of responsive fibers from acrylic fibers is studied. Various responsive fibers, such
as fibers which change their color on exposure to light or with change in temperature, have been developed
and are used commercially. However, the responsive material in these fibers are not the fiber itself but
chemicals in microcapsules attached to the fibers by finishing, and few fibers exhibit responsive properties by
itself. The partial hydrolysis of polyacrylonitrile fibers to obtain pH responsive fibers is presented in this
paper. Partial hydrolysis was effected by control of the concentration of the sodium hydroxide used in the
hydrolysis, hydrolysis temperature and time. The degree of hydrolysis was evaluated by nitrogen content of the
hydrolyzed fibers and their response, change in length, to aqueous solutions of varying pH was studied by
continually changing the pH. Significant changes in lengths with pH were observed and the gel transition
behavior varied with the conditions of hydrolysis. The hysteresis of the length change was also studied to
evaluate the possibilities of using hydrolyzed acrylic fibers as pH sensors. |
