Abstract

In order to make pure dyestuff extract from polygonum tinctoria, we tried to traditionally-using cockle shell which the extracted water should be filtered in indigo for 8 hours and at the $40^{\circ}C$, and 4.0 pH. The 1.631g of powder dye could be produced when the 10.0 ml of aqueous ammonia was added into the solution, which had been filtered for 8 hours with the 300 g of indigo plant and the 2.51 of water. The main components of two maded -dye which has traditionally made of this and has purely made of that compared by TLC, HPLC, LC/MC techniques. Finally, the antibacterial activities and deodorization ratio of silk fabrics with natural indigo were carried out, too.

쪽잎 300g를 2.5l물에 색소를 울어 내기 위하여 사용한 초산 및 황산은 제조량에는 차이는 없었으며, 공기 공급의 경우도 30분 이후에는 큰 차이가 없었다. 쪽잎 300g에 초산(5 ml/2.5l과 암모니아수(10ml/2.5l)을 넣는 경우, 염료생산량은 1.631 g으로 가장 높았다. 전통염료와 개선 (순수) 쪽 색소 제조 방법으로 제조한 쪽이 성분과 분자량이 같은 수준 이었다. 순수 색소의 제조 쪽은 전통 염색 보다 소취성이 높았고, 정균감소율은 황색포상구균과 폐렴균이 26.3%와 19.1%이었다.
