The data for application of mordanting is shown in this experiment by researching dying properties of iron-dye process and concentration changes using persimmon. The strength of persimmon-dying fabrics was controlled by diluting persimmon dye with water and iron mordanting showed the possibility of textile design. The experiments were performed with various conditions processed with iron mordanting liquid by adding water to persimmon-dying liquid and drying well. The most dark color of fabric is observed with the pure persimmon dying without adding water. As the adding water is increased, the color of the fabric is getting lighter with the amount of adding water. After process of iron mordanting, dark color of the fabric turns into dark grey and light color turns into light grey. The possibility of persimmon dying with fabric can be applied in the design of textile with deepened color.

This study purposed to restructure representative traditional patterns formatively, manufacture actual cultural products with traditional dyeing technique using persimmon, and commercialize the results of the research. Traditionally in Korea, the dying of natural fiber such as cotton, flax and silk with persimmon was called Galmul dyeing, and clothes made through Galmul dyeing were called Galot. Galot was very useful because it is strong, does not pick up dirt easily, dries easily, and is cool in summer. In addition, cloth dyed with persimmon becomes stiff, so it does not need to be starched or ironed after washing. Moreover, it does not transmit heat under direct rays and is highly air-permeable, so it is cool and useful for standing the heat. In this study, we used traditional persimmon dyeing technique, printing traditional patterns fit for contemporary people's aesthetic sense not through dip-dying but through printing. When persimmon dyeing is used in expressing patterns, it produces not only visual effect but also embossing effect due to the characteristic of persimmon that makes printed patterns stiff, so we can obtain unique texture distinguished from other printing methods. We chose seven motive patterns, which were lotus pattern symbolizing eternal life, peony pattern symbolizing wealth and rank and prosperity, character Su(壽) pattern widely used as a symbol of health, bird and cloud pattern in the Goryeo Dynasty, Sahapyeoeuisohwa(四合如意小花) pattern printed on brocade in the Goryeo Dynasty, lattice pattern, cloth pattern on wall paintings from the Period of the Three Kingdoms. From each pattern chosen as a motive was extracted unit patterns and the original pattern was restored using Adobe Illustrator. Restored patterns were restructured to be applied to cultural products fit for contemporary formative sense. Fabrics used in dyeing were cotton, linen, ramie, silk, and polyester. Although the same persimmon dyeing was applied, we produced different feelings of patterns using various fabrics and in some cases gold and silver powder was added for the effect of gloss in addition to the embossing of patterns. Using printed fabrics we manufactured tea pads, place mats, cushions, wrapping cloth for gifts, wallet, lampshades.

The natural dyeing of fabrics with persimmon juice(astringent persimmon, sweet persimmon, astringent and sweet persimmon mix) was investigated. After dyeing of cotton and silk fabrics with persimmon juice, we evaluated the dyeability of persimmon juice, the observation of fabric surface with high magnification video microscope, physical properties and color fastness with the conditions of repeating times of dyeing and variables of mordants. The results obtained from this study were as follows: The fabrics dyed with astringent persimmon have shown the highest color difference, while the fabrics dyed with sweet persimmon and the fabrics dyed with astringent and sweet persimmon mix have shown similar color differences. With the increase of repeating times of dyeing, the brightness of fabric decreased. However, $a^*$ value increased gradually, so that it became dark brown color. The $a^*$ and $b^*$ values of dyed fabrics with Fe-mordant have dropped significantly, so that they have shown achromatic colors. But the fabrics treated with other mordants have shown yellowish brown colors. On the surface of the fabrics, threads were bonded together by the viscosity of persimmon juice. Regardless of the types of persimmon juice, stiffness was increased after dying, while crease resistance was decreased. The water repellency of silk fabrics were improved than cotton fabrics after dyeing with sweet persimmon juice, but in case of cotton, it hasn't changed. Washing fastness was improved with the EM(Effective Microorganism)-fermented liquid treatment, and rubbing fastness of two fabrics was better in dry condition than in wet condition.

This study analyzes the state and products of shopping malls that sell naturally dyed products in Japan. In this study, 37 natural dyeing shopping malls were selected. The results of this study are as follows. There are many natural dying internet shopping malls located in the areas of Tokyo, Kyoto, and Okayama. The most frequent dyes were indigo, followed by akane, persimmon, mud, vegetation, and tea. The highest ordered product categories were accessories, followed by adult clothes, and interior decoration products. The most frequent products were adult hats, followed by towels (handkerchiefs), scarves, T-shirts, and bags. For the price of products, 3,000-4,000${\yen}$ was the highest for T-shirts, with 2,000-3,000${\yen}$ and 4,000-S,000${\yen}$ for newborn baby and child clothing, 5,000-10,000${\yen}$ for hats and bags, 3,000-4,000${\yen}$ for scarves, and 1,000-2,000${\yen}$ for towels (handkerchief). Concerning product information, most of the shopping malls offer the product size and the product explanations, but over half of them did not show the properties or directions for handling the product.

단감의 수확 및 저장 중에 발생한 불량과실을 이용할 목적으로 분말화하기 위한 기초연구로서 본 실험을 행하였다. 일반성분 조성은 조단백질, 조지방, 조회분의 순으로 열풍건조 처리구는 0.9-1.1%, 15.0-39.0%, 2.3-3.3%이었으며, 동결건조 처리구는 1.3-2.2%, 27.0-49.0%, 2.5%로 나타났다. 무기성분 조성은 열풍과 동결건조 처리구 모두 potassium, magnesium, phosphorus; calcium, sodium이 주요 무기성분이었으며, 다른 미량원소는 약 3.00ppm 이하였다. 주요 지방산 조성은 열풍과 동결건조 처리구에서 capric acid, lauric acid tridecanoic acid, palmitic acid, palmitoleic acid, oleic acid, linoleic acid, linolenic acid 순으로 나타났다. 동결건조 처리구의 아미노산 조성은 aspartic acid, glutamic acid가 주요 아미노산이었다. 전체적으로 열풍건조 처리구보다는 동결 건조 처리구가 다소 높은 결과를 보였다. 열풍과 동결건조에 의한 분말 제조에서는 변색과 영양적인 측면을 고려할 때 열풍건조 보다는 동결건조가 우수한 결과를 보였으며, 열풍건조가 시간은 단축되었으나 얇게 펴서 건조해야 하는 단점이 있었으며, 단순한 열풍건조 만으로는 대량생산에 의한 분말 제조는 어렵고 좀더 보완적인 방법이 강구되어야할 것으로 생각된다. 이에 반해 동결건조에 의한 건조방법은 건조시간이 다소 걸리기는 했으나 딱딱해지거나 변색의 우려가 없으며 영양학적으로도 매우 안정적이었다. 이상의 결과를 평가해 볼 때 열풍건조에 의한 분말 제조는 구체적인 보완이 필요하며, 동결건조에 의한 분말 제조가 열풍건조에서보다 우수한 것으로 결과가 나타났다. 따라서, 파찌감의 분말건조 방법은 동결건조가 효율적일 것으로 생각된다.
