This study is to examine the weaving characteristics of Hansan Mosi through a comparison of the traditional ramie weaving processes among three countries in East Asia, Korea, Japan and China.Three National degree Intangible Cultural Heritage are examined, which is Korea’s Hansan Mosi, China’s Wanzai Xiabu 万载夏布, Japan’s Ojiya-Chijimi and Echigo-Jofu 小千谷縮ㆍ越後上布. Among them, Korea and Japan’s have also been designated by UNESCO as an Intangible Cultural Heritage.As they have taken important roles since ancient times, some ancient character or factors from old writing, such as ramie harvesting from wild in China, warping directly from the connected threads form in Korea, ramie stem and outer stems soaking plus loom and shuttle shape in Japan.The most unusual characteristic of the Ojiya-Chijimi and Echigo-Jofu different from Korea and China is pictorial expressions due to its thread making process that the twist is applied to ramie threads to increase its strength. China produces various widths of ramie textiles with the wide traditional loom, but overall to meet the needs for outside, it succeeds mass production but faces quality problems. Hansan Mosi’s thread-making process can be pointed to as being the most developed and subdivided process among the three countries, it is the most developed to overcome the limitation of the bast fiber length to create the most clean and neat woven surface.Japan has developed the delicate process from the harvest to the final stage and pre-starching process applied to single thread made ramie threads similar to silk threads to effect the rest process. Overall, three countries carry their own characters throughout the process and to the final visual textile surface. Preserving tradition and implying the modern factors to find the balance is the main key to succession of ramie weaving culture and techniques for all 3 countries.
