In order to stuby the redeposition of ferric oxide and of carbon black, experiments were carried out with three kinds of synthetic fabric, nylon, polyester, polypropylene and with solution of surface-active agents, sodium dodecyle sulfate (S.D.S.), polyethylene nonyle-phenyl ether (E.P.O.). And in this cace four kinds of water which differed in hardness were used. The results were as follows : (1) The redeposition rate of Fe_2O_3 and of carbon black increased in proportion to the concentration of active agent, S.D.S. when nylon was used. In the case of polyester and polyplopylene, on the other hand, the lowest rate of the redeposition was recorded when the concentration of S.D.S. was at 0.2%. And the amounts of redeposition were remarkable in the case of each synthetic fablic in proportion as the concentration of active agent, E.P.O. was increased. (2) The redeposition rate of Fe_2O_3 and of carbon black was more influenced by th hardness of water in the solution of E.P.O. than in that of S.D.S.. And amounts of redeposition of carbon black were more susceptible to influences from the hardness of water than from those of redeposition of Fe_2O_3. (3) When the concentration of active agents, S.D.S., E.P.O., was strong the dispersion of carbon black was active. And when the hardness of water in the solution of S.D.S. and in that of E.P.O. was increased the dispersion of carbon blcak was inactive. In carbon black the disperting action was relative to the redeposition. |
