본 연구에서는 아교의 접착 특성 향상을 위해 가교제(Cross-linking Agent)를 첨가하는 방법으로 젤라틴 결합력을 증대하였다. 제니핀 첨가 아교는 물성 측정, 구조 분석, 색잔류도, 용출도, 파단강도를 측정하였으며, 수분과 자외선에 대한 내수성과 내광성을 비교하였다. 연구 결과 겔강도와 점도는 제니핀 첨가량에 따라 증가하였다. 구조분석 결과, 젤라틴에서는 구조적으로 안정된 콜라겐의 3중 구조의 흡수 피크가 관찰되었다. 색잔류도 결과, 명도가 낮아지기 때문에 피막이 관찰되는 것으로 판단된다. 용출량은 $50^{\circ}C$ 증류수에서 제니핀 첨가량이 증가할수록 용출된 아교 양이 증가하였고 파단강도는 제니핀 첨가량에 따라 증가하였다. 내수성과 내광성은 제니핀 첨가에 따른 열화 전 후 양상이 나타나지 않았다. 본 연구 결과를 바탕으로 제니핀 첨가 아교의 접착 특성을 확인할 수 있었으며 아교에 적용 가능한 실험 방법을 고찰하였다. 제니핀을 첨가한 후에도 아교 고유의 특성인 유연성, 재용해성, 접착력, 경화속도가 사라지지 않고 향상되기 때문에 균질한 아교가 확보된다면 문화재 보존 및 아교 제작에 적용이 가능할 것으로 기대한다.

This study focused on the properties natural dyeing and natural material and on the development of functional material for well-being in apparel industry. Comus officinalis Siebold et Zuccarini is used as natural dyeing material which had been reported that have curable effect for unbalanced immunity, geriatric diseases like urinary tract system, diabetes, hypertension, arthritis, tinnitus, hyperhidrosis and women's diseases like hypermenorrhea. And this material also has anti-cancer effect so that can restraint cancer cells. 3 kinds tester of cotton, wool and silk are dyed by boiled with each dye (flower, fruits, bark of tree) as first dyeing and dried in the shade. These testers are done by post-mordanting method. Aluminium Potassium(Alk(SO4)2), Cuprie Sulfate($CuSO4{\cdot}5H2O$), Stannous Chloride($SnCl2{\cdot}2H2O$), Ferrous Sulfate($FeCl2{\cdot}4H2O$), Titanium Sulfate 24% aqueous solution(Ti(SO4)2) are used as mordants. Dyeing results of Comus officinalis Siebold et Zuccarini flower and bark are shown as yellow color series. And dyeing result of fruits is pink color series. Silk shows the best dyeing property. As the point of view for dyeing property, Ti, Sn, Fe would be the properchoice for mordant. Following results are extracted in this study. Yellow color is resulted in dyeing with Cornus officinalis flower as non-mordanting condition. Yellowish red color is come from dyeing with Comus officinalis fruit as non-mordanting condition. Grayish yellow tone is resulted in dyeing with bark as non-mordanting condition. Orange tone color with Ti-mordanting, green tone color with Sn-mordanting and gray tone color with Fe-mordanting is resulted respectively. However light-fastness of Comus officinalis(flower, fruit, bark) is very low as 1 or 2 level in non-mordanting condition, Comus officinalis flower dyeing is turned out 3 or 4 level and fruit dyeing is 4 or 5 level, bark dyeing is 2 or 3 level with Ti-mordanting respectively. Eventually Comus officinalis fruit has the best light-colorfastness property among all of dyes. dry cleaning colorfastness of Cornus officinalis(flower, fruit, bark) is good as 4 or 5 level in Ti-mordanting condition, perspiration-colorfastness of Cornus officinalis(flower, fruit, bark) is good as 4 or 5 level in Ti-mordanting condition, With these results, this study could conclude that dye-ability, colorfastness problem is getting better after mordanting process and practical usage would be possible.
