In the previous paper, it was found that the dyeability of polypropylene fiber was markedly increased by the treatment with a mixed solution of hydrochloric acid and sodium hypochlorite and it was anticipated that chlorine or chlorine water would be the main reactant of this solution. Therefore, we have tested the dyeability of fibers treated with pure chlorine and saturated chlorine water and discussed the origin of dyeability with elementary analysis or flame reaction of the reacted fiber. Results were as follows :　1 Fibers treated with saturated chlorine water, even within ten minutes at room temperature, were well dyed with basic dye (Chrysoidine). According to elementary analysis, chlorine atom was found in the reacted fiber (0.93%), but it was decreased to 0.32% by boiling for 30 minutes in 5% KOH solution, afterwhich the dyeability was lost. The colour of well dyed fiber was orange and that of hard dyed one was light-orange. It was supposed that a small amount of hydrochloric acid had penetrated into the fiber and made a salt with Chrysoidine.　2 A dyeability of fibers treated with chlorine gas was decreased to half the one which was treated with saturated chlorine water.　It was further decreased on the fiber treated with dried chlorine gas. The colour of the fiber was light yellow and Cl atom was found in it (0.18%). lts dyeability was lost after boiling for 20 minutes in 5% KOH solution, thereafter it was unable to confirm the existence of Chlorine in the fiber even by flame reaction.
