Sericin has been removed in textile industry to improve the luster and hand of silk textile. Therefore, the sericin was considered as useless material. However, recently sericin has attracted researcher's attention since unique properties of sericin including high water retention, UV protection, and...

실크 섬유란 무엇인가? | 누에로부터 생산되는 실크 섬유는 피브로인 두 가닥을 세리신이 둘러싸고 있는 천연 유래 복합섬유이다. 실크 섬유의 직경은 누에품종에 따라 많은 차이가 있으나, 백옥 잠을 비롯하여 우리나라에서 생산되고 있는 실크 섬유들의 직경은 약 30 µm 정도이다 (Chung et al. | |
정련 공정을 거친 실크 섬유의 구조는 어떠한가? | , 2015a). 여기에서 정련 공정을 통해 세리신을 제거하게 되면, 피브로인 두 가닥이 외부로 드러나면서 섬유의 직경은 15 µm 이하로 감소하게 되고, 외형은 좀 더 뚜렷하고 규칙적인 납작한 삼각형 구조를 띄게 된다. 정련에 따른 이러한 외형적인 구조 변화에 기인하여 실크 섬유는 광택이 향상되고, 촉감이 부드러워 정련된 실크 직물(degummed silk textile)은 생직물(raw silk textile)보다 의복 재료로써 상업적으로 우수한 가치를 갖게 된다. | |
세리신을 화장품과 의료용소재로 사용하려는 이유는 무엇인가? | 그러나, 최근 들어 세리신에 대한 많은 연구를 통해 세리신이 상처치유 능력을 가지고 있으며(Aramwit et al., 2009; Nagai et al., 2009; Teramoto et al., 2008), 우수한 자외선 저항성(Gulrajani et al., 2008), 산화 저항성(Suzuki et al., 2004), 주름 방지성(Padamwar et al., 2005), 보습성 (Jang and Um, 2017; Padamwar et al., 2005)을 가지고 있다는 연구결과가 보고되고 있다. 이에 따라 세리신을 화장품과 의료용소재로 응용하기 위한 연구들이 다수 진행 되고 있다. |
