Abstract: Disclosed is a nozzle block for electrospinning which is able to simultaneously electrically spin two or more different types of polymer spinning dopes, wherein a single-layer distribution plate for dividing a planar space within the nozzle block into two or more segments is installed within the nozzle block. The apparatus is simple because a single-layer distribution plate is installed instead of a conventional multi layer distribution plate. A hybrid nano fiber laminate can be prepared without any additional laminating procedure because two or more different polymer spinning dopes can be simultaneously electrically spun through different nozzles arranged within the same nozzle block. It is possible to prepare a hybrid nano fiber nonwoven fabric or filaments or the like composed of two or more types of nano fibers different in thermal properties or physical properties because their fiber diameter or polymer type are different from each other.

Abstract: A method for producing a continuous filament made up of nanofibers is disclosed. A ribbon-shaped nanofiber web is prepared by electrospinning a polymer spinning solution onto a collector 7 applied with a high voltage, the collector 7 consisting of (I) an endless belt type nonconductive plate 7a with grooves having a predetermined width (u) and depth (h) formed at regular intervals along a lengthwise direction and a conductive plate 7b inserted into the grooves of the nonconductive plate, and then the nanofiber web is isolated (separated) from the collector 7, focused, drawn and wound. A continuous filament (yarn) made up of nanofibers can be produced by a simple and continuous process by providing a method for continuously producing a filament (yarn) by an electrospinning technique without a spinning process. The focusability and the drawability can be greatly improved by orienting nanofibers well in the fiber axis direction. Due to this, a continuous filament of nanofibers more excellent in mechanical properties can be produced.

Abstract: Disclosed are a nano fiber reinforced composite and a method of manufacturing the same. A spinning dope (nano fiber forming spinning dope) having a viscosity capable of fiber formation upon electrospinning and a spinning dope (spinning dope for matrix) having a viscosity incapable of fiber formation upon electrospinning are electrically spun onto the same collector with a high voltage applied thereto through different nozzles of the same nozzle block with a high voltage applied thereto. In the nano fiber reinforced composite, nano fibers are uniformly arranged between matrix components with no fibers formed therein, the nano fibers being arranged at an orientation angle of 90° or less relative to the longitudinal axis of the composite material. The nano fibers used as reinforcing material can be uniformly distributed within matrix components by a single procedure, and the contact area between the nano fibers and the matrix components are very large because the diameter of the nano fibers used as reinforcing material is small.
