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，健康的重要性被置于许多事情之上。因为人们明白，他们赚的钱和没有健康的生活都无关紧要。纺织材料在白天与我们一起出现在各个领域，它们很容易受到微生物的攻击。因此，在大多数情况下，应该考虑以简单和环保的方式摆脱这些攻击的方法。在此背景下，本研究调查了纺织产品的消毒过程。为此，棉织物分别被两种不同类型的细菌污染。这些细菌种类是金黄色葡萄球菌(ATCC 29,213) 和大肠杆菌(ATCC 25,922)。然后通过一套臭氧和UV-C应用系统用臭氧和UV-C处理不同时间的细菌污染的织物样品。此外，还测试了基于过氧化氢的消毒。在这些过程之后，进行了细菌减少测试。此外，还拍摄了一些织物样品的 SEM 图像以观察表面改性。结果发现，特别是使用臭氧气体，可以在很短的应用时间内对棉织物获得必要和充分的消毒效果。
