Japanese history
Raw silk is sold in bundles called skeins, but the sizes and specifications of the skeins varied from country to country and from region to region. In Europe and the United States, the skeins were hung in a frame called "fuwari" and wound around a bobbin before being processed, but the fuwari had to be replaced to match the various sizes of the skeins, which forced a complicated process. From the end of the 1870 s, Japanese raw silk skeins were standardized to a size (1 meter and 50 centimeters in 綛長) that is most suitable for rotating the fuwari at high speed (standardization of skeins), and at the same time, the fuwari had to be replaced, which made it easier to handle. Making the 綛長 1 meter and 50 centimeters has spread abroad and is adopted in today's silk reeling industry. The silk industry was the first industry in Japan to hold a global standard. This book describes the global history of Japanese raw silk, especially in the United States, being welcomed and successfully developing and expanding the market.
