SEM image of polyester nanofiber prepared by laser irradiation.

Prof. Dr. Ohkoshi and his co-workers has developed developed the production technology of ultrafine fibers (less than 40 nm diameter) by drawing using the laser-heating system. By use of the laser heating, not only the increase of production rate, but also the cut down on the energy loss on fiber production, which save the earth, are obtained. By the production system, new high-performance fibers, for example the nano-fibers are developing in rapid succession.
