Abstract
Melt electrospinning was able to achieve a thin fiber with nano-order diameter by controlling the amount of discharge. Biomaterial is one of the fields where nanofiber is actively studied. The challenge of Japan for application and mass production of nanofiber noticed at present is also explained in this paper. Hirose paper Co. Ltd. proposed the production technique for an electrospinning in bubbles which continuously arise in polymer solution by applying high voltage. In NEDO project of Japan, the productivity was improved by increasing number of nozzle and became 50 times as great as the previous one. In Shiga Prefecture, the manufacturing equipment was also developed.
