|Abstract:||Flexible adsorptive polymeric fiber was prepared from a mixture of activated carbon powder, paraffin wax and polypropylene. Activated carbon powder was first coated with paraffin wax. The optimum amount of wax was found to be about 23% by weight of activated carbon. The activated carbon-wax mixture was then mixed withpolypropylene with the ratio of PP:activated carbon of 87.13 by weight. The best method to produce adsorptive fiber is, first, to melt-spin the mixture into continuous fiber. Then this as-spun fiber is drawn to the highest possible draw ratio in order to give it adequate strength for further processing. Finally the paraffin wax is extracted with hexane. The performance of the fibers prepared in this way was evaluated from methylene blue adsorption capacity. After extraction the fiber could adsorb more methylene blue than before. Drawing also enhanced the adsorption capacity. The adsorption capacity of the activated carbon in the drawn and extracted fiber is approximately 97% that of the starting activated carbon powder. The adsorptive fiber displays mechanical strength that is high enough for further processing in general textile machineries.|
