NANOFIBER MANUFACTURING DEVICE AND NANOFIBER MANUFACTURING METHOD

摘要

Disclosed is a nanofiber manufacturing device (100) for manufacturing nanofibers (301) by electrically stretching a starting material liquid (300) in a space, the nanofiber manufacturing device being provided with: a discharge body (115) which has a plurality of discharge holes (118) for discharging the starting material liquid (300) into the space, the discharge body (115) comprising a front end portion (116) at which openings (119) that are the front ends of the discharge holes (118) are one-dimensionally disposed side by side at predetermined intervals, and two side surface portions (117) which are disposed such that the interval therebetween increases with increasing distance from the front end portion (116) and extend from the front end portion (116) so as to sandwich the discharge holes (118) therebetween; a charged electrode (121) which is disposed at a predetermined interval from the discharge body (115); and a charged power source (122) which applies a predetermined voltage between the discharge body (115) and the charged electrode (121), thereby maintaining high production volumes of nanofibers per unit time and per unit area, and improving and uniforming the quality of nanofibers by suppressing the influence of ion wind.
