Abstract

Based on above best preparation condition for semi-finished polyacrylonitrile (PAN) fiber via dry spinning at alkaline conditions, for example, hydrolyzing temperature keeps at 95?, the mass fraction of NaOH is 15%, water treatment is 60 min, the effect of bath ratio and the recycling of the bath on fiber water absorptivity were further investigated. Furthermore, the max recovery rate of the alkali solution was discussed. The results show that bath ratio has little effect on the water absorptivity of superabsorbent fiber obtained by hydrolyzing PAN precursor. The bath can be recycled at most three times, and maxmium recovery rate of the alkali solution is about 70%.
