Investigation of the Disinfection Effect of Some Environmental Friendly Applications on Cotton Fabrics

ABSTRACT

Today, the importance of health is kept on top of many things. Because people understood that neither the money they earn nor the life they live without their health is of any importance. Textile materials are together in every field during the day with us and they can be exposed to the attacks of microorganisms quite easily. Hence, ways of getting rid of these attacks in easy and environmental approaches should be considered in most cases. In this context, disinfection processes of textile products were investigated in this study. For this aim cotton fabrics were contaminated separately with two different types of bacteria. These bacterial species are Staphylococcus aureus (ATCC 29,213) and Escherichia coli (ATCC 25,922). Then bacterial contaminated fabric samples were treated with ozone and UV-C for different periods of time by a set of ozone and UV-C application system. Additionally hydrogen peroxide based disinfection has been tested as well. After these processes, bacterial reduction tests were carried out. In addition, SEM images of some fabric samples were taken to observe the surface modification. As a result, it was found that necessary and sufficient disinfection effect was obtained on cotton fabric in very short application time by using especially ozone gas.

摘要

今天，健康的重要性被放在许多事情之上. 因为人们明白他们挣的钱和没有健康的生活都不重要. 纺织材料和我们在一天的每一个领域都在一起，它们很容易受到微生物的攻击. 因此，在大多数情况下，应考虑以简单和环保的方式消除这些攻击. 在此背景下，本研究探讨纺织品的消毒过程. 为此，棉织物分别受到两种不同类型细菌的污染. 这些细菌种类是金黄色葡萄球菌（ATCC 29213）和大肠杆菌（ATCC 25922）. 采用臭氧和UV-C处理系统，对细菌污染的织物样品进行不同时间的臭氧和UV-C处理. 此外，过氧化氢消毒也进行了测试. 在这些过程之后，进行了细菌还原试验. 另外，对部分织物样品进行了SEM观察. 结果表明，特别是使用臭氧气体，在很短的使用时间内对棉织物达到了必要而充分的消毒效果.
