This paper describes the effects of varicts soils on the antibacterial activity of antibacterial agents in the commercial anticrobial treatment socks. In this paper, we deals with six types of soils (Japanese sake, sause, soy sause, milk, juice and miso soup) and make a wear test, and examines the change of the antibacterial activity of socks contaminated with various soils.The results obtained are as follows.(1) When the commercial anticrobial treatment socks were contaminated with soils artificially, the inhibition percenage decreased than the socks with no soils. But, inhibition percntage increased again after washing and removing the soils. It was recognized positive correlation between the reflectnace of socks contaminated with soils and the inhibition percentage. This tendency was similar when the socks were washed after three days. When the socks were washed after one month, however, the recovery of the inhibition percentage was not recognized, because the soils contaminated was not removed easily.(2) In the case of wear test, the width of clear zone of the socks weared was smaller than the no-wear socks, and the antibacterial activity of the socks weared decreased. This result shows that the growth of microorganisms becomes actively when the soils were adhered even if the antibacterial agents was not removed by washing operation. It was recognized the negative correlation between the number of bacteria and each component of soils, and the coefficient of correlation of untreated socks was higher than the commercial anticrobial treatment socks. Because, the bacteria adhated to the commercial anticrobial treatment socks were killed or inhibitioned by the antibacterial agents.When the textile product was contaminated with soils, there was a remarkable growth of microorganisms. Therefore, it was necessary to remove immediately the soils by washing even if the socks was treated by the anticrobial treatment.
