Abstract

Hospital patient clothing material was treated with a mixture of chitosan in order to enhance functionality, such as the durability and dimensional stability of the cotton fabric used. Chitosan is a natural polymer with excellent biocompatibility, however there is a deteriorating adherence efficiency. The addition of a nanosilver colloidal solution in accordance with a prescribed ratio can further increase the performance of chitosan. Changes in the structural characteristics and physical properties of the chitosan/nanosilver treated fabric were observed in a comparison with fabric treated only with chitosan. The add-on ratio increased when the mixing ratio of nanosilver colloidal solution was higher; however, the crystalline structure of the treated fabric remains similar. In the case of CH3/NS1 treated fabric (where the mixing ratio of chitosan and nanosilver solution was 3:1) the K/S value, whiteness index, wet tensile strength, and wrinkle recovery angle were superior. The dimension stability, pilling resistance, and abrasion resistance of the fabric treated with a mixed solution increased in comparison to the fabric treated only with chitosan. The chitosan/nanosilver treated cotton fabric used for patient clothing material has excellent physical properties.

실제 환자복 소재로 사용되는 면직물의 내구성, 치수안정성, 구김회복성 등의 성능을 개선하고 경제적인 측면을 고려한 기능성 가공을 하기 위하여 가공제로 천연고분자이며 생체적합성이 우수한 키토산과 고착효율이 좋지 않은 키토산의 단점을 보완하면서 부가적인 성능을 기대할 수 있는 은나노 콜로이드용액을 혼합비에 따라 처리하고, 키토산 단독 처리직물과 비교함으로서 가공처리직물의 구조 및 물리적 특성의 변화를 살펴보았다. 은나노 콜로이드용액의 혼합비가 클수록 부착률이 증가하였으며, 키토산/은나노 콜로이드용액 가공에 따른 결정화도의 저하나 백도 저하도 일어나지 않았다. 건(乾)강도와 강연도는 키토산 단독 처리직물이 가장 좋았으나, 습(濕)강도와 건(乾), 습(濕)방추도는 은나노 콜로이드용액의 혼합비가 3:1일때 가장 우수하였다. 은나노의 혼합비가 커질수록 가공처리 직물의 치수변화율이 감소하여 형태안정성이 향상되었고, 필링성 및 마모강도도 저하되지 않아 면직물이 환자복 소재로서 내구성이 우수한 물리적 특성을 나타내었다.
