The objective of this study was to evaluate the possibility for the coffee filter paper of Hanji. In this study, the samples for Hanji filter papers were prepared with three different mulberry fiber contents of 10, 30 and 50%(w/w). Surface brightness and apparent density of hand-made Hanji decreased with increasing mulberry fiber contents. However, values of thickness, tensile strength, wet tensile strength, burst strength, and folding endurance for hand-made Hanji increased by increasing the contents of mulberry fibers due to fiber-to-fiber bonding. The results of the coffee extraction test using the developed filter papers showed no significant differences between commercial filter paper and Hanji filter paper. Therefore, Hanji filter paper containing more than 30%(w/w) mulberry fiber may have potential uses for the dripped coffee filter application from a physical property point of view.

본 연구에서는 국산닥, 태국닥, 중국닥의 원료를 사용하여 펄핑, 표백, 고해, 초지, 건조의 방식을 변화시켜 총 3500 여장에 이르는 한지를 한지제조 전문가가 일정한 방법에 따라 제 조하였고 그 특정들을 조직적으로 검토하였다. 이러한 연구는 한지의 물성이 닥섬유의 처 리공정에 의해 어떻게 영향을 받는지 연구를 통계적으로 가능하게 하였다. 본 연구에서는 육재펄핑과 일광표백의 효과, 외발뜨기와 쌍발뜨기의 효과, 고해방식의 차이, 먹퍼집성에 대 해 결과들을 보이 고 있다. 육재 펄핑과 일광표백이 한지의 물성에 어떠한 영향을 미치는지 알아보기로 하였다. 현 재는 많은 한지 업자들이 육재펄핑보다는 가성소다 펄핑 (그림에서는 약품펄핑으로 표기), 일광표백보다는 차아염소산 나트륨 (그림에서는 약품표백으로 표기)을 사용하는 것이 보통 이다. 육재펄핑과 일광표백을 실시한 한지는 열단장, 인열강도, 내절도를 약품펄핑이나 약 품표백보다 높이는 효과가 있음을 알 수 있었다. 하지만 약품을 사용하는 경우 리그닌의 용출이 더 수윌하므로 백색도는 약품을 사용하는 경우가 더 유리하였다. 국산닥의 경우 육 재펄핑과 일광표백을 한 경우 먹퍼짐성이 약품사용 한지보다 크지 않음을 볼 수 있었다. 한국의 전통적인 외발뜨기 초지방식은 일본의 쌍발뜨기 방식에 비해 많은 물리적 우수성 을 보이고 있다. 외발뜨기가 쌍발뜨기에 비해 열단장, 신장율, 인열지수 및 내절도 모두가 우수함을 잘 보이고 있다. 섬유의 성질과 관련하여 전체적으로 조명해 보면, 열단장, 인열 지수는 국산닥이 가장 높으며, 내절도는 태국닥이 우수하였고, 중국닥의 경우 모두 매우 불 량함을 알 수 있다. 이것은 아마도 처리중에 과도한 표백을 실시하지 아니하였는가 하는 의구심을 들게한다. 열단장과 신장율 역시 국산닥이 우수하였다. 글씨를 쓸 때, 붓이 나가 는 정도를 마찰게수로 짐작해 보았다. 동 마찰계수와 정 마찰계수는 국산닥이 낮은 편이였 다. 마찰계수가 낮다는 사실은 한지의 표면이 더 매끄럽다고 표현될 수 있는데, 역시 국산닥 으로 제조한 한지가 붓이 나가는데 유리하지 않을까 하는 추측을 할 수 있다. 본 실험결과 는 한지 사용자들의 느낌과 상관관계를 얻어내어서 확인해야 할 것이다. 닥방망이로의 고해나 칼비터에 의한 고해나 큰 물성적으로 큰 차이를 보이지는 않고 있 었다. 단지 섬유의 차이가 고해방식의 차이보다 월등히 크다는 사실을 보이고 있다 이러한 점은 섬유장의 길이에서도 볼 수 있다. 칼비터가 섬유를 절단하기만 하고 닥방망이 고해가 섬유장의 변화를 일으키지 않는다면 틀림없이 평균 섬유장의 차이가 생길것이다.

The dyeing properties of mulberry fiber/cotton blended fabric with Inonotus obliquus are studied through the investigation of the effects of dyeing conditions, such as the concentration of Inonotus obliquus extract colorants, dyeing temperature, time, and pH values on dye uptakes (K/S). In addition, the effects of mordant on the dye uptakes and antibacterial activities are investigated. The results are summarized as follows. The dye uptakes of dyed fabric increased gradually with an increase concentration of Inonotus obliquus extract colorants, the K/S value was the highest when the dyeing temperature was $60^{\circ}C$ for a duration of 60 minutes. As the pH value of the dyeing solution changed to more acidic, the dyeability of the, fabric was improved. The K/S value recorded the highest at pH 3. The antibacterial activities of dyed and unmordanted mulberry fiber/cotton blended fabric showed a high Staphylococcus aureus reduction rate.

This study performed the evaluation of skin temperature, heart rate, humidity and temperature inside clothing, and subjective sensation to estimate the physiological responses of the human body and its feeling of comfort for developing value-added dox fabric. Experiments were performed on five healthy adult women whose average age was 21, at climate chamber in which temperature, relative humidity and air current were set up below $28{\pm}5^{\circ}C$, $50{\pm}10%$, 0.2m/s, respectively. Two kinds of clothes were used for the experiments: 100% cotton and dox clothes. The clothes were identical in size and form, and the attire consisted of long-sleeved shirts, long trousers, and socks. The experiment was performed for 30 minutes using ergometer. The results are as follows. 1) It showed low skin temperature of forearm, breast, back, forehead and lower leg in exercise, but high skin temperature of them in recovery. However skin temperature of thigh and foot increased from rest to recovery. 2) It showed significant difference (p<0.001, p<0.01) in average skin temperature between cotton and dox clothes. Cotton clothes had a higher average skin temperature compared to dox. Not only was there a significant difference in temperature inside clothing (p<0.001), this was also the case with humidity inside the clothing (p<0.001).

Culture industry is appearing as an important sector of economy. Many kinds of culture industry like movie, music, drama, animation and game are creating enormous wealth all over the world. Fashion is a kind of culture industry too and even sometimes treated as art. Korean fashion is not treated as real culture but still as a part of textile industry. Internationally Korean fashion has not yet much to show, and despite of it's potential it does not attract much interest from other countries. In this paper properties and effects of mulberry handmade paper clothes were investigated with five clothes made of it. In making handmade mulberry paper clothes various techniques could be applied and these techniques could bring new effects. Because mulberry handmade paper does not have little flexibility than ordinary texture, much efforts should be put to the detail works. Handmade mulberry paper clothes have enormous potential as art, because various approach could be applied.

To satisfy consumers' desire to enjoy their own individuality and cultural trends, the discovery of various materials and the expression of materials embodying their characteristics are increasingly important in the fashion jewelry industry. This study examines, paper mulberry fiber, a raw material of hanji that has been excavated as a new material for fashion jewelry, is durable as wall as, soft and easy to form, has a unique texture along with, excellent aesthetic quality, and expresses various colors, thereby differentiating itself from traditional fashion jewelry materials. The material itself also has symbolic significance as an approach to discovering new sustainable materials for fashion jewelry to ensure increased specificity of the product based on the premise of freedom of expression. The weight and optimal drying time of chicken fiber were derived for the study of fashion jewelry expression using the characteristics of paper mulberry fiber. The techniques of casting, deflection, packing and winding (winding beads with fibers and straps) were derived and four brooches were produced in total. This study is meaningful for the future of, the fashion jewelry industry as it presents the uses of new materials such as paper mulberry fiber to induce multidisciplinary consumption and to suggest a direction for the creation of new value-added products. Further, in order to expand the realm of fashion jewelry industry with our own competitive products that have secured our cultural identity and uniqueness in the global market, there must be continued follow-up research on mass production methods for industrialization.

The purpose of this study was to develop an effective marketing strategy for socks made of paper mulberry fiber, a new natural fiber, by understanding consumers' concerns and perception about the product and its quality in several dimensions. The first survey determined their perception of the products' image before using it. The second survey gauged consumer satisfaction with product quality after a two-week home-use test. Factor analysis using Cronbach's a and ANOVA analysis were performed for statistical analysis. In conclusion, consumer image perceptions of socks of mulberry fiber were classified into four categories -'practicality', 'wellbeing', 'high-quality' and 'traditionality'. The survey revealed differences between men's and women's perception of the 'practicality' and 'high-quality' factors. The women recognized a mulberry fiber sock as being more practical but of lower quality than did the men. And the quality satisfaction of the product was classified into four factor 'durability', 'suitability, 'wearability' and 'care-easiness'. In the case of 'suitability', men were more satisfied with the product than the women and in 'suitability' and 'wearability', a group of over 40' year-old consumers was more satisfied. The analysis of a relationship between image perception and satisfaction showed that a consumer group that perceived this product to have more 'practicality', 'high-quality' and 'well-being' was also more satisfied with the product. However, the 'traditionality' factor was unrelated to consumer satisfaction.
