본 연구는 출토직물의 세척을 위한 천연계면활성제 선정을 위하여 그 특성과 세척성을 알아보는데 목적이 있다. 이를 위해 대조군으로 합성계면활성제인 SDS (Sodium dodecyl sulfate)와 천연계면활성제 중 LES (Disodium laurethsulfosuccinate), apple wash (Sodium cocoyl apple amino acids), tea saponin (Saponin), cornacopa (Decyl glucoside), coco betain (Cocamidopropyl betaine) 등 5종을 선별하여 계면활성제의 FT-IR (Fourier transform infrared spectroscopy) 분석으로 구조를 확인하고, pH와 표면장력 측정으로 특성을 파악하였다. 인공오염포 4종과 출토직물편에 대한 세척성 실험을 수행하였다. 그 결과 인공오염포에 대해서는 apple wash, tea saponin, cornacopa가 세척성에 있어서 SDS만큼 좋은 것으로 나타났으며 출토직물편에 대해서는 tea ssponin과 coco betain의 세척성이 좋은 것으로 나타났다. 따라서 세제의 안전성과 세척성을 감안할 때 천연계면활성제 중 tea saponin이 출토복식 세척을 위한 천연계면활성제로써 적합한 것으로 사료되었다.

Nowadays, Korean consumers prefer drum-type washing machines to pulsator-type washers. Washing is a complex process involving the interaction of numerous physical and chemical influences. The main factors in the washing operations are the washing chemistry of the detergent along with the mechanical input, the wash temperature, and the time provided by the washing machine. Heavy-duty detergents that are used in drum-type washing machines contain different components from those used in vertical-axis washing machines. The bath ratio and the mechanical actions to which laundry is subjected are different between the drum-type and the vertical-axis washing machines. In this study we examined the effects of wash temperature, wash time, detergent concentration, and revolution speed on the removal of soils from artificially soiled cloths in a drum-type washing machine with heavy-duty commercial detergent. We used multiple regression analyses to find the relative importance of the factors and the optimum washing conditions. The results of these experiments showed that the washing temperature was the most important factor in the effective removal of most soils. This was followed by the washing time, the detergent concentration, and finally the revolution speed. In this study it was found that superfluous amounts of detergent did not sufficiently increase the soil removal rate. Koreans who are used to washing with cold water should increase the wash time to launder more efficiently.

Nowdays, costumer's washing behavior were often times for remove to light-duty dirt. The purpose of this study is to provide the most effective washing conditions of detergent concentration and temperature conditions for help save energy and water resources required to the washing process. Washing conditions were as follows: 2 kinds of detergents and 4 types of artificially soiled fabrics were used. Detergent concentration was 0%, -10%, and -20% below the recommended conc. of manufacturer's standard. Temperature of bath was $20^{\circ}C$ and $40^{\circ}C$. The results of this study were as follows: First, washing performances of all kind of artificially soiled fabric improved as the temperature of bath at $40^{\circ}C$. Second, the test was conducted under the condition of decreasing respectively -10% and -20% below of the recommended concentration of manufacturer's standard detergent. The average of washing efficiency was not considerably affected by the reduction of 10% below of manufacturer's standard. Third, in case of the water temperature were $20^{\circ}C$, polyester/cotton blended fiber were higher degree of washing efficiency than cotton fiber.

This study was undertaken to develop the artificially soiled cloth using clay and dyed oleic acid as model soil and to evaluating the detergency by determination of K/S value and chemical analysis. The results obtained were as follows : 1. Correlation were determined between the K/S value and chemical analysis data for the detergency of developed model soil at various conditions and it was found that model soil could be extensively used for the washing examination. 2. The surface reflectance of soiled cloth with clay-oleic acid mixture was measured two wave length band that was converted K/S values and the amount of two components was individually calculated. Positive correlation were found between detergency that obtained from chemical anlysis and K/S values. Therefore, proposed method of soiled cloth with clay-oleic acid mixed soiles could be extensively used for detergency experiment. 3. The attached state of soil of on the artificially soiled cloth which was observed under a scanning electronic microscope showed a different pattern by the sort of soil. And the difference of attached state of soil had great influence upon the detergency. 4. The composition of clay was changed and formated of noncrystalinity was vanished by calcined at $800^{\circ}C$. Because of a noncrystalline of clay, artificially soiled cloth could be prepared more uniformly but the detergency was decreased.

조선시대 양반가의 장례시 매장방식은 회곽묘제를 사용하였으며, 그 유물들이 현대에 형태를 유지한 채로 출토되는 경우가 종종 있다. 그러나 그 내부에서 발견되는 섬유유물들은 예전에는 염직물이었을 것으로 예상되나 오랫동안 시즙과 수분에 의해 오염되어 고유의 색상 및 물성에 변화를 일으킬 수 있다. 이러한 오염은 출토 후에도 계속적으로 유물의 변퇴색 및 열화에 영향을 미칠 것으로 예상되므로 적합한 세척이 요구된다. 따라서 본 연구는 습식세척 후 출토염직물의 색변화를 최소화할 적합한 세정조건을 조사하기 위하여 적색계 7종, 청색계 1종, 황색계 6종, 녹색계 4종, 자색계 4종의 천연염색 염색포(견과 면)을 만들어서 이를 돈육과 함께 6개월간 냉장보관한 후 꺼내어 물, 음이온계면활성제(SDS), 비이온계면활성제(TritonX-100), 천연계면활성제(Saponin) 등 4종의 세정액를 이용하여 $20^{\circ}C$와 $40^{\circ}C$의 온도에서 습식세척하여 염직품들의 색상변화에 대한 영향을 조사하였다. 그 결과 색상의 변화는 세정온도, 섬유소재, 세정제, 이용한 염료의 종류에 따라 차이를 나타내었다.
