Antiseptic treatments of fishing cotton yarns with the Cu-naphthenate and other metallic salts of naphthenic acid were carried on by two bath method : firstly treated with 1, 5, 10, 20, or 50% soln. of naphthenic acid in 0.5-1% ammonia and then dipped in 5% soln. of metallic salts, such as Cu, Hg, Zn, Al salts. Effectivness of these treatments are shown in Fig. 1-4 and Table 1. and summarized as follows : Hg and Cu-naphthenates are most effective, and practically 10-20% solns. of naphthenic acid in the 1% ammonia were applied to the yarn, and nextly fixed in the 5% metallic salt soln. Application of Cu-naphthenate, accompanied by Cu2O, is more effective than the simple treatment with Cu-naphthenate.
