TECHNICAL FIELD The present invention relates to a spinning device for producing a two-component composite nanofiber and a method for manufacturing a two-component composite nanofiber using the same, and more particularly, to a spinning device for producing a two- The present invention relates to a radiation tube, and more particularly, to a method for producing a high quality two-component composite nanofiber web using the radiation tube.

The term " two-component composite nanofiber "of the present invention is used to include both core-sheath type composite nanofiber and side-by-side type composite nanofiber, Is used to mean also an eccentric core-sheath type composite nanofiber.

As a conventional technique for producing core-sheath type composite nanofibers, a method of electrospinning a spray solution for forming a sheath and a spinning solution for forming a core through a nozzle of a sheath / core type (double pipe type) with electrostatic force has been widely used.

However, since the above-mentioned conventional method relies solely on the electrostatic force to perform electrospinning, the discharge amount per nozzle unit per unit time per unit time is extremely low to 0.01 g, which leads to a problem of productivity and difficulty in mass production.

In general, the production of nanofibers through electrospinning is 0.1 to 1 g per hour, and the solution discharge rate is very low, ranging from 1.0 to 5.0 mL per hour [D. H. H. Renecker et al., Nanotechnology 2006, Vo 17, 1123]

Specifically, Nano Letters, 2007, Vol. 7 (4) 1081 discloses another conventional art in which a single nozzle having an inner diameter of 0.4 mm among the composite nozzles in which two nozzles are arranged side by side is provided with SnO 2 The precursor solution was supplied, and the other nozzle having an inner diameter of 0.7 mm was charged with TiO 2 A method of producing TiO 2 / SnO 2 composite inorganic nanofibers in a side-by-side configuration is provided. However, since the conventional method depends on only the electrostatic force, the discharge amount per nozzle per unit time The productivity is deteriorated, and nozzle replacement and cleaning are difficult.

In Polymer, 2003, Vol. 44, 6353, a Teflon needle having an inner diameter of 0.7 mm and a thickness of 0.2 mm was used, and two kinds of solutions were simultaneously injected into a cylinder pump so that two kinds of solutions were combined at the needle part And a platinum electrode is placed in a solution to perform electrospinning to produce a side-by-side composite nanofiber. However, since the conventional method also depends only on the electrostatic force, the discharge amount per nozzle per unit time is very low, There is a problem that it is difficult to remove and replace the nozzle and clean it.

In addition, the above conventional methods have a problem that the phenomenon in which the spinning solution falls on the collector in a solution state not in the form of a fiber (hereinafter referred to as "droplet phenomenon") is severely generated, and the quality of the two-component composite nanofiber web deteriorates.

The object of the present invention is to minimize the risk of work due to the application of high voltage and to greatly improve the productivity of the two-component composite nanofiber and to prevent the droplet phenomenon in the production of the nanofiber, And to provide a spinning device for manufacturing a two-component complex nanofiber.

Another object of the present invention is to provide a method for producing high-quality two-component composite nanofibers with high productivity by using a radial tube for producing the two-component composite nanofibers.

In order to achieve the above object, the present invention provides a spinning device for producing a two-component composite nanofiber, comprising: (i) a spinning tube main body Ta having one shape selected from a cylindrical shape and a conical shape; And a polygonal tube-shaped hollow portion Tb formed along the longitudinal direction of the radiation tube main body Ta, and the corner portions of the hollow portion Tb on the polygonal tube are in contact with the outer peripheral surface of the radiation tube body Ta (Ii) a spinning liquid distribution tube body (1a) connected to the spinning tube (T) and having a shape selected from a cylindrical shape and a cone shape, A hollow portion 1b on the polygonal tube and a hollow portion 1b on the polygonal tube are formed in the tube body 1a along the longitudinal direction of the radiating liquid distribution tube main body 1a, And a nozzle 1c provided along the longitudinal direction of the liquid distribution tube main body 1a. The corner portions of the hollow portion 1b on the polygonal tube are in contact with the outer peripheral surface of the radiating liquid distribution tube main body 1a (1) having a structure as shown in Fig.

The present invention also relates to a method of controlling a radiation source of a radiation source, comprising the steps of: (i) applying a high voltage to the radiation tube (T) and the radiation liquid distribution tube (1) (Ii) supplying the first spinning solution into the nozzle 1c constituting the spinning solution distribution tube 1 and supplying the first spinning solution into the hollow portion 1b on the polygonal tube constituting the spinning solution distribution tube 1, (Iii) supplying the first spinning solution supplied into the nozzle 1c of the spinning solution distribution tube into the hollow portion 1b on the polygonal tube of the spinning solution distribution tube, after supplying the second spinning solution different from the first spinning solution The second spinning liquid is supplied to the collector 2 through the corner portion of the polygonal tube hollow portion Tb constituting the radiation tube T by centrifugal force and electric force by the voltage generator 6 To prepare a two-component composite nanofiber.

The present invention relates to a process for producing a two-component composite nanofiber with high productivity (discharge amount) because it uses electrostatic force and centrifugal force at the same time, facilitates solvent volatilization and recovery, (Drop phenomenon) is effectively prevented, thereby improving the quality of the two-component composite nanofiber web.

As shown in Fig. 1, the spinning apparatus for producing a bicomponent composite nanofiber according to the present invention comprises (i) a spinning tube main body Ta having one shape selected from a cylindrical shape and a conical shape, and And a polygonal tube-shaped hollow portion Tb formed along the longitudinal direction of the radiation tube main body Ta. The corner portions of the hollow portion Tb on the polygonal tube are connected to the outer peripheral surface of the radiation tube body Ta, A radiation tube T having an abutting structure; And (ii) a radiating liquid distribution tube main body (1a) connected to the radiating tube (T) and having a shape selected from a cylindrical shape and a conical shape, The longitudinal direction of the radiating liquid distribution tube main body 1a is set at each of the corner portions of the hollow portion 1b on the polygonal tube and the hollow portion 1b on the polygonal tube formed along the longitudinal direction of the distribution tube main body 1a A radial distribution tube 1 having a structure in which corners of the hollow portion 1b on the polygonal tube are in contact with an outer peripheral surface of the radiating liquid distribution tube main body 1a, .

One or two or more nozzles 1c are provided along the longitudinal direction of the main body 1a of the radiation tube in each of the corner portions of the hollow portion 1b on the polygonal tube constituting the spinning solution distribution tube 1. [

The radiation tube (T) and the radiation liquid distribution tube (1) may be integrally formed or formed from the beginning, or may be separately manufactured and then connected to each other by assembly.

Next, as shown in FIG. 1, the method for manufacturing the two-component composite nanofibers according to the present invention will be described. (I) While rotating the spinning tube (T) and the spinning solution distribution tube (1) A high voltage is applied to the spinning tube T and the spinning solution distribution tube 1 by the nozzle 6 and then the first spinning solution is supplied into the nozzle 1c constituting the spinning solution distribution tube 1 A second discharging liquid different from the first discharging liquid is supplied into the hollow portion 1b on the polygonal tube constituting the discharging liquid distributing tube 1 and then supplied into the nozzle 1c of the discharging liquid distributing tube 1 And the second spinning solution supplied into the hollow portion 1b on the polygonal tube of the spinning solution distribution tube is centrifugally separated from the edge of the hollow portion Tb on the polygonal tube constituting the radiation tube T by centrifugal force and electric force, (6) in the direction of the collector (2) where a high voltage is applied by the voltage generator (6) To prepare a two-component composite nanofiber.

At this time, the first spinning solution is supplied into the nozzle 1c using the first spinning solution supply pipe 3a, and the second spinning solution 2b is injected into the hollow portion 1b on the polygonal tube by using the second spinning solution supply pipe 3b. .

As shown in FIG. 2, the first spinning solution (A: spinning solution for forming a core) is injected through a nozzle 1c having a relatively small diameter constituting a spinning solution distribution tube into a corner of a hollow portion on a polygonal tube (Tb ') of the hollow portion on the polygonal tube constituting the radiation tube through the hollow portion 1b on the polygonal tube of the spinning liquid distribution tube having a relatively large diameter, A first spinning solution (A: core forming solution) which maintains a core shape throughout the entire length of the edge portion Tb 'because the solution flow is relatively faster than the spinning solution (B: spinning solution for forming a sheath) (B: spinning liquid for forming a sheath) is wrapped around the circumference of the polygonal tube-shaped hollow portion of the radiating tube so that the core-sheath shape is maintained over the whole length of the corner portion Tb ' , Prize In the corner portions (Tb ') the top end of the core-sheath type bicomponent composite nanofibers is formed.

The manufacturing mechanism of the core-sheath type two-component composite nanofibers according to the present invention described above is completely different from the mechanism of manufacturing the core-sheath type two-component composite nanofibers by arranging the two nozzles in a core-sheath form .

Since the two-component composite nanofibers are produced simultaneously at the plurality of corner portions Tb ', the productivity is greatly improved as compared with the conventional nozzle type method. When the shape of the spinning liquid distribution tube 1 is changed, Based composite nanofiber can be produced.

Wherein the two-component composite nanofiber is a core-sheath type composite nanofiber or a side by side type composite nanofiber, and the core-sheath type composite fiber is an eccentric core- It may be a composite nanofiber.

As a practical example, a spinning solution for core formation (first spinning solution) is supplied into a nozzle 1c constituting a spinning solution distribution tube 1, and a spinning solution for forming a sheath (Second spinning solution) is supplied to prepare the core-sheath type composite nanofiber.

At this time, when the radiation tube 1 provided with three nozzles 1c in each of the corner portions of the hollow portion 1b on the polygonal tube constituting the radiating liquid distribution tube 1 as shown in Fig. 4 is used, Three core-sheath type composite nanofibers can be produced.

As an example of implementation, one of the two different polymer solutions is used as the first spinning solution to be fed into the nozzle 1c constituting the spinning solution distribution tube 1, the other spinning solution is fed into the spinning solution distribution tube 1, Cis-shaped composite nanofiber or side-by-side composite nanofiber is prepared as a second spinning solution supplied into the polygonal tube-shaped hollow portion 1b constituting the core-sheath type composite nanofiber.

The core part of the core-sheath type composite nanofiber prepared as described above is dissolved in an organic solvent or the like to produce a hollow fiber.

As another embodiment, one of two kinds of precursor solutions containing different minerals is used as the first spinning solution supplied into the nozzle 1c constituting the spinning solution distribution tube 1, Is used as a second solution to be supplied into the hollow portion (1b) on the polygonal tube constituting the spinning liquid distribution tube (1) to prepare a bicomponent composite inorganic nano fiber.

The thus prepared two-component composite inorganic nanofiber is stabilized and carbonized to produce a single-component or two-component inorganic nanofiber.

As another embodiment, the polymer solution is used as the first spinning solution supplied into the nozzle 1c constituting the spinning solution distribution tube 1, and the precursor solution containing the mineral is supplied to the spinning solution distribution tube 1 Is used as a second spinning solution to be supplied into the polygonal tube-shaped hollow portion 1b constituting the core-sheath type composite nanofiber, wherein the core component is a polymer and the sheath component is an inorganic substance.

A water-soluble polyvinyl alcohol solution is used as a first spinning solution supplied into a nozzle 1c constituting a spinning solution distribution tube 1 , And a polyacrylonitrile solution is used as a second spinning solution to be fed into the polygonal tube-shaped hollow portion 1b constituting the spinning solution distribution tube 1 to form a core-sheath type composite nanofiber, Soluble polyvinyl alcohol is removed with water to prepare a hollow polyacrylonitrile fiber, and then the prepared hollow polyacrylonitrile fiber is stabilized and carbonized to produce a hollow carbon nanofiber.

At this time, if a radiation tube provided with two or more nozzles 1c in each of the corner portions of the hollow portion 1b on the polygonal tube constituting the spinning solution distribution tube 1 is used, the porous carbon nanofibers are produced.

The hollow carbon nanofibers or the porous carbon nanofibers prepared as described above are useful as a filter material, a secondary battery membrane material, an electrode material, a highly functional garment material, and a drug delivery material.
