In order to examine the detergency and the redisposition of a polyester fiber, we made the tests using carbon-black as soil and examined its dispersion under the following testing conditions. Testing liquid (Ho…ion-exchange water, H_1…5°hard water) Detergents(Bo…100%E.P.O., B_1…25%E.P, O., 25%Na_5P_3O_<10>, 50%Na_2SO_4) Strength of a detergent liquid(Co…1%, C_1…0.01%, C_2…0.05%, C_3…0.1%, C_4…0.2%, C_5…0.4%) As for the estimation of the detergency and the redeposition, we measured surface reflectivity rate, and as for the degree of dispersion after leaving untouched carbonblack solution for a fixed space of time. we measured its absorbances and by comparing them evaluated the degree of dispersion. Following are the thief results of the detergency and redeposition tests. (1) As for the detergency, ion-exchange water showed higher rate of detergency than hard water. And both ton-exchange water and hard water showed marked detergency when they were mixed with Na_5P_3O_<10>. The B_1 detergent solution of more than 0.05% strength showed high degree of detergency. (2) As for the redeposition of a clean polyester fiber, hard water showed higher degree of detergency than ion-exchange water. As for the detergent agent the B_1 detergent showed high degree of detergency, in both cases of ion-exchange water and hard water. (3) As for the relation of the dispersion of carbon-black with the redeposition, the higher degree of dispersion it showed, the less the redeposition was. Therefore, we can suppose that the dispersion of carbon-black imposes effecfive check upon its redisposition.
