이질풀 추출물로 염색한 면직물의 염색성과 항식중독균성

Abstract

This study was conducted to develop antibacterial hand towel and dishcloth against food poisoning bacteria, and to examine the dyeability and the antibacterial activity of cotton fabrics against food poisoning bacteria, which was dyed with 1% extracts of Geranium nepalense at 50 to 60℃ for 60 minutes. Surface colors of cotton fabrics treated nothing, alum [AlK(SO4)2 ·nH2O], and calcium hydroxide [Ca(OH)2] with mordants showed grayed-yellow group, that treated copper sulfate (CuSO4) with mordant was grey-brown group, and that treated sulfate of iron (FeSO4 · 7H2O) made grayed-green group. Hue value of cotton fabrics dyed with the extracts of Geranium nepalense and dried until twenty times was an order of descent Y, that dried thirty to forty an order of descent YR. Cotton fabrics dyed with the extracts of Geranium nepalense had the antibacterial activity against food poisoning bacteria such as Staphylococcus aureus, Escherichia coil and Salmonella typhimurium by over 99.99%. And that dried over thirty times showed the antibacterial activities against food poisoning bacteria by 52.91%.
