  • Allergic dermatitis is one of the most prevalent diseases in young/juvenile children worldwide. In this research, extracts with persimmon sap-stained fabrics (rayon and cotton) exhibited an elevation in $CD4^+$ cell numbers. MMP-2 and MMP-9 expressions by Hematoxylin-Eosin staining and immunohistochemistry revealed that the expressions were decreased by addition of the extracts. The present results collectively suggest that the active ingredients of persimmon sap-stained fabrics play an important role in inhibition of DNFB-induced-atopic symptoms in vivo.

  • This study analyzed differences between Jumchi-Hanji papers not dyed and dyed with persimmon juice (50% concentration) in five strength properties (tensile, wet tensile, tearing, bursting, and folding strengths). For the analysis, the undyed and the dyed Jumchi-Hanji papers were made by Jumchichigi during 40 minutes and made with the Dakji of different layer (a layer, two layers) and Choji method (Oebal-teugi, Ssangbal-teugi). Differences between Jumchi-Hanji papers dyed with the different concentration of persimmon juice (20% vs 70%) in the five strengths were also identified. For this examination, Jumchi-Hanji papers were made with two layer Dakji (Oebal-teugi Choji method) and by Jumchichigi during 60 minutes. Jumchi-Hanji papers made in this study were used as test samples. As a result, Jumchi-Hanji papers dyed with persimmon juice had higher tensile strength (CD), wet tensile strength (MD, CD), and bursting strength than those of undyed Jumchi-Hanji papers. However, tearing strengths (MD, CD) of dyed Jumchi-Hanji papers were lower than undyed Jumchi-Hanji papers. Folding strengths (CD) of dyed Jumchi-Hanji papers were low but the folding strengths (MD) of them were high compared to undyed Jumchi-Hanji papers. In addition, the concentration of persimmon juice influenced the five strength properties of Jumchi-Hanji. The tensile, wet tensile, and bursting strengths of Jumchi-Hanji papers dyed with a 70% concentration were higher than those one of Jumchi-Hanji papers dyed with a 30% concentration while the tearing and folding strengths of Jumchi-Hanji papers dyed with a 70% concentration were lower than Jumchi-Hanji papers dyed with a 30% concentration.

  • The pattern cases for Korean traditional socks are named "beoseonbongip" which means a pouch to keep patterns for making "beoseon". "Beoseon" is Korean traditional socks. This study is to identify characteristics of the pattern cases and to develop cultural products based on the unique characteristics of the pattern cases. One hundred fifty one photos of "beosonbongip" were collected and quantitatively and qualitatively analyzed. Seventy percent of them were made between Joseon Dynasty and 1960s. As a result, most of the collected pattern cases are rectangular and square shapes, red color, and silk fabrics, and sizes of them are from 9cm to 15cm. A few pattern cases with different sizes and colors were also observed. Most pattern cases were made by fixing two among four triangle pieces which made by folding four tips of a rectangular or square cloth and then puting a not or a loop on the remaining triangle pieces in order to open and close the pattern cases. In a small number of the pattern cases, three of the four pieces were fixed and a button, a bead, a broach, or two nots or two loops were put on the other piece for opening and closing. Products such as apparels, bags, pouches, frames, and key holders were made using "beoseonbongip" form and construction method. This shows that "beoseonbongip" is a useful motive for creative product development.

  • 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.

  • This study compares the strength properties of Jumchi-Hanjis dyed with 70% and 100% persimmon juice concentrations and undyed Jumchi-Hanjis. The Juumchi-Hanjis were made from Dakjis (mulberry papers), which were mixed with different ratios of fibers from paper mulberries originating in Korea and Thailand, including wood pulp from Canada. Research results showed that tensile, wet tensile, and bursting strengths of Jumchi-Hanjis dyed with 70% concentration were higher than those of undyed Jumchi-Hanjis. However, the tearing strengths of the dyed Jumchi-Hanjis were lower than those of undyed Jumchi-Hanjis. The wet tensile strengths of Jumchi-Hanjis dyed with 100% concentration were higher than those of dyed with 70% concentration. The increase and decrease of tensile, tearing, and bursting strengths depending on persimmon juice dyeing differed as per the mixing ratio of the raw materials of Jumchi-Hanjis. Dyeing with 100% persimmon juice concentration tends to be more useful than 70% to increase the tensile (MD) and wet tensile strengths of Jumchi-Hanjis containing only Korean mulberry fibers (90%) and wood pulp (10%) as raw materials. Dyeing with 100% concentration tends to be less useful than 70% to increase the tensile, tearing and bursting strengths of Jumchi-Hanjis with high proportions (90% or 60%) of mulberry fibers from Thailand.

  • The purpose of this research is to analyze the effects of persimmon juice and hibiscus flowers extract to perform combination dyeing of silk fabrics, with respect to color changes, fastness, and functionality. The optimal conditions as a result, were shown at 100% of dye concentration, $40^{\circ}C$ of dyeing temperature and 30 minutes of dyeing time while in terms of dye uptake depending on the kind of mordants and methods. The highest K/S value was recorded at pH 3, pre-mordants of $CuSO_4$, and $SnCl_2$, post-mordanting. After repeated dyeing and post-mordanting, various color change occurred with mordant treatments. Color fastness of dyed fabrics with hibiscus flowers extract was improve considerably by combination dyeing with persimmon juice extract. In aspects of functional properties, it showed excellent results of 99% deodorization rate, 99.9% Staphylococcus aureus rate and 99.9% Klebsiella pneumoniae.
