Abstract

In order to enhance the functionality of a cotton fabric actually used as the clothing material for patients, the fabrics are treated with chitosan/nanosilver mixed solution. The nanosilver has excellent biocompatibility, not causing an environmental pollution as a natural polymer, provides expectation of an additional performance, does not harm human beings, and shows a strong antibacterial activity even in a small amount, and supplements chitosan, which is disadvantaged if used alone for fabric treatment. This study evaluates functional improvement of the clothing material for patients and observes through hygienic characteristics which are the most important function. In antibacterial activity of the fabrics treated with chitosan/nanosilver mixed solution against Staphylococcus aureus, higher ratio of chitosan was observed to achieve better antibacterial activity. In antibacterial activity against Klebsiella pneumoniae, higher ratio of nanosilver was observed to achieve better activity. Regarding laundry durability of antibacterial activity after repeated laundering, activity against Staphylococcus aureus was little reduced, but was greatly lowered against Klebsiella pneumoniae. Deodorization activity was excellent as the mixed ratio of chitosan was increased, and air permeability, moisture permeability and moisture regain were reduced as the mixed ratio of nanosilver was increased.

환자복은 생리적 쾌적성이 저하되고, 위생 문제가 심각하게 대두되지만 기존의 소재로는 쾌적성, 위생성 등 환자복으로서의 요구 성능을 충족하기 어려우므로 실제 환자복 소재로 사용되는 면직물의 성능을 개선하고, 가공 효과와 경제적인 측면을 고려한 기능성 가공을 함으로써 위생적 특성의 변화를 도모하였다. 가공제로는 천연고분자이며 생체적합성이 우수한 키토산과 아울러 키토산의 단점을 보완하면서 부가적인 성능을 기대할 수 있는 은나노 용액을 혼합비율에 따라 처리하여 항균성, 소취성, 수분 특성 등의 위생적 특성의 변화를 검토하였다. 가공처리 직물의 항균성은 키토산/은나노 혼합용액의 처리농도가 200ppm 이상에서 아주 우수한 항균성을 보였으며, 황색포도상구균은 10회 세탁 후에도 항균성이 감소되지 않았으나 폐렴간균에 대한 세탁내구성은 크게 저하되었다. 또한 키토산의 비율이 높을수록 아주 우수한 소취성을 보였으며 공기투과도, 투습도, 수분율은 은나노의 혼합비가 커질수록 다소 감소하였는데 이는 은나노 입자의 부착 때문으로 생각되었다.
