  • This research was carried out to investigate the Hanji sludge(black color)-wood fiber and wood particle composited applied by waste sludges arising from the making process of Hanji (Korea paper). In experimental design, four levels of the mixed ratio of Hanji sludge to wood fiber or wood particle(10:90, 20:80, 30:70 and 40:60), three kinds of the resin(PMDI, urea and phenol resin)and three kinds of the specific gravity(0.6, 0.75 and 0.9) were designed to determine the tensile strength of Hanji sludge-wood fiber and wood particle composites. From the results and discussion, it may be concluded as follows: In Hanji sludge-wood fiber and wood particle composites, tensile strengths showed decreasing tendency absolutely by increasing Hanji sludge additive, but clearly increase with the increase of specific gravity. In Hanji sludge-wood fiber composites, there were no differences between PMDI and urea resin-bonded composites, but phenol resin-boned composites were made possibly until the addition of 30% Hanji sludge. On the other hand, Hnji sludge-wood particle composites(SpGr=0.6) have very low tensile strength values. But they were made favorably until the addition of 20% Hanji sludge in Hanji sludge-wood particle composites(SpGr=0.9).

  • This study analyzes and compares Hanji made with loess to Hanji made with kaolin, two yellow-based inorganic pigments, in terms of its physical properties, optical properties, and color fastness to light with the aim of using it as a fashion material. Hanji made by adding inorganic pigments showed an approximately 20% retention ratio on average. This figure was similar to those of loess and kaolin. Physical properties were analyzed, with the following results. A higher amount of additives lowered the apparent density and increased thickness and bulk. In general, inorganic pigment-added Hanji had lower tensile strength, bursting strength, and folding endurance compared to non-additive Hanji. The analysis of optical properties showed a lower brightness index for Hanji made with inorganic pigments compared to non-additive Hanji. When comparing the two inorganic pigments, the brightness of Hanji made with kaolin was higher. Regarding color fastness to light, loess showed level 4 and kaolin showed level 5 when 25% inorganic pigments on pulp were added to Hanji. Thus, Hanji made by adding inorganic pigments during the manufacturing process may perform well as materials for fashion because the additives enhanced both the color fastness to light and the bulk while maintaining the strength. In addition, Hanji dyed with inorganic pigments may have the potential to serve as materials for the fashion industry while still retaining the characteristics of Hanji.

  • 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.

  • Hanji woven fabrics are currently developed as a new multi-functional textile material due to their excellent properties of humidity control function, antibiotic, deodorant efficiency, and absorbency. In this study, Hanji union fabrics (silk $yarn{\times}Hanji$ tape yarn) were produced and their weavability, physical property, shrinkage, and color fastness were evaluated. Hanji paper and the tape yarns of $13g/m^2$ and 1.5-8.0mm were produced by a cylinder mould machine and a micro-slitter, respectively. From the weavability evaluation, a critical width of Hanji tape yarn as possible picking was found to be 2.0mm. As the width of tape yarn increased, the breaking stress and strain of the tape yam increased. Especially, after picking, the tensile property of Hanji tape yarn approached to the values of Hanji yarn. The shrinkage of dyed Hanji fabrics was 3.0% or less. On the evaluation of fastness to washing, the grade of Hanji union fabric showed good values and better value to the staining rather than color change. Also instead of washing, dry cleaning is desirable to the fabric. Hanji fabric was excellent in color fastness in grades 4-5 both to rubbing and perspiration, but was 3 grade to light resistance. To increase color fastness to light, plied yarn or union fabric with excellent light resistant yarn such as polyester may be applied.

  • Hanji costumes has four aspects that allow the creator or artist to create many variations. The pictorial effects of Hanji costumes are produced through variations in the dyes and brushes used for its application. The amount of water and texture of the Hanji mixture also influences the Hanji clothing. This effect was expressed using a dry brush technique, a dripping technique, India inks, and fragments from other Hanji works. A second aspect of Hanji clothing is the coloring effect in the Hanji costumes. The coloring is due to the fibers in the preparation mixture and the uniqueness of the dyes. The Hanji clothing was dyed various colors and patterns by dip dyeing, block dyeing, silk screens, digital printing. The third aspect of Hanji imagination in clothing is the decorative details. The details in Hanji clothing can be seen using frills, pleats, tucks and ribbons. The last variation of Hanji clothing can be expressed through crafting techniques. These techniques are the quality of paper string, cuts in the paper and paste ingredients. With Hanji cloth, it is possible to plait, roll, and crample into other flexible & useful materials.

  • To evaluate the anisotropic characteristics of Korean traditional paper-Hanji, the physical and mechanical characteristics of hand-made hanji, and machine-made hanji were investigated in this research. The densities of copying paper and newsprint paper appeared to be two times higher than the densities of hand-made hanji using Ssangbal sheet forming and hanji made of paper mulberry fiber. The breaking length, and tear index of both Hanji using Owangbal sheet forming, and hand-made Hanji using Ssangbal sheet forming appeared to be different according to the directions in paper. The breaking lengths of Hanji using Owangbal sheet forming showed little differences according to the directions. Breaking length of Hanji using Ssangbal sheet were slightly higher than those of Hanji using Owangbla sheet forming. The breaking lengths of machine-made hanji, copying paper, and newsprint paper were two to four times higher than those of hand-made Hanji. The breaking length showed higher differences according to the direction than the tear index. The tensile strength according to the directions in paper showed significant differences (${\alpha}$=0.05) in all papers used in this research.

  • Hanji(Korean traditional paper) is made from bark of paper mulberry(Broussonetia kazinoki). For a long time, Hanji has been used in various fields, such as paintings, printing paper, as specialty paper. The utilization of Hanji will become more and more diverse. One of the characteristic properties of Hanji is a long life time comparing to western paper. The mucilage which must be used in Hanji manufacturing should effect the conservation properties of Hanji. The effectiveness of the mucilage in aging of Hanji was evaluated in this paper. Strength properties of thermal aged Hanji made with synthetic mucilage decreased more slowly than those of Hanji made with natural mucilage. As prolonged aging time, all Hanji made mucilage increased oxidation index. But, Hanji made with PAM was most stable in oxidation of cellulose.

  • The new way of utilization of Hanji need to develop for adding high value added. An watermarked Hanji was prepared with non-mulberry mixed fibers and the properties were investigated. The mechanical properties of non-mulberry fiber mixed Hanji were very similar to mulberry fiber Hanji. The non-mulberry fiber mixed Hanji was a little brighter than original Hanji. The air permeability and pore size of the hot pepper fiber mixed Hanji were decreased depending on the content of hot pepper fiber. The printing ability of watermarked Hanji made of non-mulberry mixed fibers was higher than that of original paper mulberry Hanji. The preservation properties of non-mulberry fiber mixed watermarked Hanji were almost same as those of the original Hanji.

  • With environmental pollution becoming a serious problem, recently there has been increased interest in the environment and health. In addition, the development of materials for environmentally friendly and functional clothing has increased. Environmentally friendly products that use bark fibers of the mulberry(dak) tree are expressed in terms of dak fiber and Hanji yarn. This research analyzed consumer's perceived images of Hanji and Hanji yarn infant clothing. The research results are as follows. Based on analyzing images of Hanji and Hanji yarn, Hanji was categorized into four images that can be described as natural, pure, decorative, and functional, and Hanji yarn infant clothing was categorized into three images that can be described as natural, decorative, and functional. Based on the analysis of well-being elements in subjects' lifestyles, the following four inclinations were found: environmental friendliness, pursuit of novelty, life care, and environmental protection. On this basis, the subjects were categorized into three groups: the trend-pursuing group, the life-care group, and the social responsibility group. Subjects' perceived images of Hanji and Hanji yarn infant clothing were investigated, and these products were found to have a strong image of being Korean, traditional, and natural, while being weakly perceived as comfortable, functional, and practical. Analyzing the correlation between images of Hanji and Hanji yarn infant clothing and lifestyle groups revealed that these products were not perceived differently according to group. This study showed that Hanji and Hanji yarn are terms that are commonly associated with positive clothing material. However, both Hanji and Hanji yarn are perceived negatively in terms of functional image, which is an important factor in clothing material. In addition, even among consumers who pursue a lifestyle based on well-being, the functional image of Hanji yarn was not perceived highly. Hence, it is necessary to further examine the effect of terms such as Hanji and Hanji yarn on consumer choices. Therefore, caution is considered needed when using such terms in the marketing of related products.
