의복재료로서 한지를 더 효율적으로 사용하기 위해, 직접염료를 이용하여 한지를 염색하였다. 한지의 주성분은 면, 마와 같은 셀룰로오스이지만, 많은 불순물을 포함하고 있고, 섬유제품과 내부구조와 표면구조가 다르므로, 다른 염색거동을 보일 수 있다. 또, 물을 흡수하면 한지의 물성은 크게 저하하므로, 염색 과정에 의해 강도가 변화될 가능성이 있다. 따라서, 본 연구에서는 직접염료를 이용한 한지의 염색특성을 셀룰로오스 섬유인 면, 마와 비교하여 고찰하고, 염색에 따른 인장강도 변화를 살펴보았으며, 염료의 물에 의한 블리딩 및 일광 견뢰도를 평가하였다. 직접염료로 한지를 염색할 때, 한지는 $25^{\circ}C$에서 최대흡진율을 보인 반면, 면과 저마는 $60^{\circ}C$에서 최대흡진율을 보였으며, 염색 후, 한지의 인장강도는 감소하였다. 낮은 온도에서 염색하였을 때 블리딩이 컸고, 염색한 한지의 K/S 값이 크면 블리딩 이 커지는 경향을 보였다. 직접염료로 염색한 한지의 일광견뢰도는 면, 마에 비해 떨어지지 않았다.

The utilization of non-woody fibers with the fast growing annual plants has occurred in the paper industry to replace wood and preserve environment of the earth. The non-woody fibers generally used for papermaking are paper mulberry, gampi, manila hemp, rice straw, bamboo, and coton linter etc.. Recently Kenaf has been spot-lighted for the same application. Kenaf is an annual plant of Hibiscus species of Malvaceae family. Kenaf, a rapid growing and high harvesting non-woody fiber plant, was identified as one of the promising fiber sources for the production of paper pulp. This study was carried out to investigate the pulping characteristics of Kenaf bast fiber for Hanji (traditional Korean paper) manufacturing by different pulping methods, such as alkali, alkali-peroxide and sulfomethylated pulpings. It was possible to make superior grade of Hanji. Especially sulfomethylated pulping was resulted in superior pulp in terms of higher yields and qualities in comparison to those of the other pulping methods. Hanji from sulfomethylated pulp was shown the highest brightness of over 60% and higher sheet strength. In addition, the morphological features of pulp fibers (pulp compositions) affect to the sheet properties. Therefore the effect of fiber distribution index(FDI) which was calculated from the data of Confocal laser scanning microscopy(CLSM) on the sheet properties of Kenaf Hanji was also discussed.

Electromagnetic interference (EMI) shielding is an important issue in modern daily life due to the increasing prevalence of electronic devices and their compact design. This study estimated EMI-shielding effect (EMI-SE) of small ($8-14{\times}17mm$) Hanji (Korean traditional paper) doped with carbon nanotubes (CNTs) and compared to Hanji without CNT using $^2H$ (92.1 MHz) and $^{23}Na$ (158.7 MHz) nuclear magnetic resonance (NMR) peak area data obtained from 1 M NaCl in $D_2O$ samples in capillary tubes that were wrapped in the Hanji samples. The simpler method of using the variation of reflected power and tuning frequency by inserting the sample into an NMR coil was also tested at 242.9, 158.7, and 92.1 MHz. Overall, EMI shielding was relatively more effective at the higher frequencies. Our results validated that NMR methods to be useful to evaluate EMI-SE, particularly for small, flexible shielding materials, and demonstrated that EMI shielding by absorption is dominant in Hanji mixed with CNT.

Background: To investigate the possibility of using Asarum sieboldii as an environment-friendly fumigant for protecting organic cultural heritages, the inhibitory effect of A. sieboldii extract against wood rot fungi on Hanji was examined. Methods and Results: The physical, optical, and morphological properties of Hanji inoculated with Trametes versicolor and Tyromyces palustris, and exposed to the n-hexane fraction of A. sieboldii extract, were measured. The physical properties were expressed as weight loss, zero-span tensile strength and viscosity and the optical properties were depicted by luminance and chromaticity ($L^*$, $a^*$, and $b^*$). The results showed that, the n-hexane fraction of A. sieboldii extract inhibited the growth of fungi on Hanji, and preserved its condition. At a concentration of 25 mg, the n-hexane fraction of A. sieboldii extract maintained zero-span tensile strength, increased viscosity, and restricted discoloration of Hanji. It also was confirmed that the weight of fungi infested Hanji exposed to the extract did not decrease. Scanning electron microscopic images revealed that the spores and hyphae of T. versicolor and T. palustris were not present on Hanji during treatment with > 25 mg of the n-hexane fraction of A. sieboldii extract. Conclusions: These results indicate that the n-hexane fraction of A. sieboldii extract by virtue of its antifungal effectiveness may help in preserving Korean paper cultural heritages, including Hanji.

Hanji is a traditional Korean handmade paper, which has been known in ancient Far East as excellent quality calligraphic paper for more than 1,500 year. Hanji is mostly made of Korean paper mulberry bast fibers, and if properly processed, normally lasts for more than 1,000 years with significant strength and still recognizable calligraphic writings or drawings on it. Dochim is a special way of Hanji calendering process, but is turned out to be quite different from modern calendering (machine calendering) in several aspects. In Dochim process, mechanical impacts were applied vertically to the surface of papers. Compared to the modern calendering, Dochim increased paper gloss much more, but paper smoothness a little less. By the Dochim process, densification occurred and the degree of densification was more sensitive to the fiber type in the Dochim process than in the calendering method.

The aim of this study is to develop Casual Hanbok design made of Hanji yarn textiles for New Silver generation women. The New silver generation is a coined word which has meaning of a newly silver generation and it is distinguished from pre-silver generation. New silver generation is a generation that is independent and given active role by their age groups and generational characteristic. The concept of silver generation was introduced from maturity market in Japan. This study was based on analysis about their preference of forms, colors, and materials of Casual Hanbok. The survey target were 270 female over age 50 living in Daejeon City. The analysis methods used frequency and percentage. The results were summarized as following. Although almost of them haven't worn Casual Hanbok, they had the positive recognition on wearing one. They preferred longer length jacket to traditional Korean style, shorter length of skirt. They also preferred the traditional sleeve shape and knotted buttons. On the foundation of this fact, 2 styles consist of 5 Casual Hanbok design items made of functional material - Hanji yarn textiles that have antimicrobial, deodorant, quick drying, far infrared radiation which are not harmful to health - for New silver women were suggested. One style was 3 items - blouse, vest, skirt - which are the sense of Korean tradition with activity by patch. The other was 2 items - jacket and skirt - which are the sense of Korean tradition with modern way by quilting. Lastly, these garments were evaluated by 13 experts, they were satisfied with 2 styles and all items. As this study were based on the Elderly women living in Daejeon city, it had the limitation on applying of preference styles to all the New silver generation.
