A Study on The Antimicrobial Effect of Organic Silicon Quaternary Ammonium Salt Using Cotton, Polyester, and Wool
이은영
ABSTRACT
This study has been carried out for the antimicrobial effects of organic silicon quaternary ammonium salt with which cotton, polyester, and wool were treated respectively, using Esherichia coli and Proteus bulgaris which are experimental bacteria for clothing materials. As a results, the best antimicrobial effects of organic silicon quaternary ammonium salt came out from cotton ; the next form wool ; and lower from polyester. With the changes of the temperature, the antimicrobial effect with soaking time, there was no changes with cotton after 10 minutes passed. It seemed to have reacted entirely in the early stage. The longer the soaking duration was, the higher the effect from polyester was. The effect from wool was increased until 20 minutes, but decreased after 30 minutes. The optimal processing condition of cotton was in the condition of liquor ratio 40:1, concentration 0.5%, soaking time 5 minutes, and temperature 30oC ; wool was 1.5%, 20 minutes, and 60oC ; polyester was 2.0%, 30 minutes, and 30oC respectively. The changes of the effect by washing was as followings : The processing effect on cotton and wool appeared to be everlasting, since they had no changes by washing 10 times ; while, it was remarkablely decreased with polyester by washing only once, and was almost disappeared after washing 10 times, which means that polyester has no durability to washing.
