Process of preparing continuous filament composed of nanofibers
First Claim
1. A process of preparing a continuous filament composed of nanofibers, wherein a polymer spinning liquid is electrospun to a collector 7 through nozzles 5 to obtain a nanofiber web 17a of ribbon form, then the nanofiber web 17a is passed through an air twister 18 and twisted to obtain a nanofiber filament 17b of a continuous filament form, and then the nanofiber filament 17b is drawn.

Abstract
Conventional electrospinning was problematic in that it is incapable of making a continuous filament (yarn) by a simple and continuous process. To solve the above problem, there is provided a method for making a continuous filament consisting of nanofibers according to the present invention, wherein a polymer spinning liquid is electrostatically spun to a collector 7 through nozzles 5 to obtain a nanofiber web 17a of ribbon form, then the nanofiber web 17a is passed through an air twister 18 and twisted to obtain a nanofiber filament 17b of a continuous filament form, and then the nanofiber filament 17b is drawn.
