Accordingly, the present invention has been developed to solve the problems of the prior art as described above, and by attaching a fine dust dust protection net with a built-in magnet to the window frame of a door that opens and closes a vehicle window, it protects it from pests or fine dust when the window of the door is opened. The purpose of this is to provide a fine dust dust protection net for vehicle doors that can safely protect occupants and allows fresh air from the outside to pass through, but rainwater or fine dust to not penetrate inside.

The fine dust dust net for a vehicle door according to the present invention for achieving the above object is a fine dust dust net for a vehicle door which is attached by a neodymium magnet on the inside of a door where a window is opened and closed, and the dust net is one surface of which is fine. It is provided with a fine dust net that blocks dust, the other side is provided with a ventilation net, and the fine dust net is provided with a magnet jolle for attaching and fixing the opening end of the fine dust net to the door, and the opening end of the ventilation net is provided in the ventilation net. An elastic band to adhere to the door is provided, and both ends of the elastic band may be provided with Velcro for attaching and fixing the opening end of the ventilation network to the bent panel of the door.

In addition, the fine dust net is provided on the back surface of the dust-proof layer of a network structure composed of synthetic fiber filament yarns, that is, polyester yarn, and has pores of 0.05 to 0.1 μm, antibacterially treated nano-fiber layer, and the back surface of the nano-fiber layer It may include a protective layer of a mesh structure that is provided to protect the fiber layer.

According to the insect and dust protection net for blocking fine dust for vehicles of the present invention, an invention made in the size of a vehicle door is attached to and installed on a steel door with a built-in magnet, and air passes through and circulates even when the window of the door is opened, It can protect vehicle occupants safely by blocking the inflow of pollutants, such as pests, rainwater, etc. Since it can be installed on a door with excellent product compatibility, it has the advantage of being able to use it universally.

In the production of the anti-vibration net to be provided in the present invention, a mosquito net composed of polyester yarn is prepared in one step (10), and a hot melt resin is applied to one side of the insect screen in a dot (DOT) form to prepare a mosquito net (fabric 1).

In the second step, the nylon resin is spun in the form of nanofibers with the spinning device 20 on the hot-melt-coated surface of Fabric 1.

At this time, the radiation amount of nanofibers per unit area (1 m2) is appropriate to be about 1 to 10 g, and optimally, about 1 to 3 g can be obtained.

In the third step, another insect screen (fabric 1) is overlaid on top of the radiated dust screen so that the nano-sized dust net that is radiated onto the screen (fabric 1) can be adhered to the surface of the fabric, and then open the entire fabric overlaid with these two sheets. When the adhesive heat bonding roller 30 is passed through, the hot melt resin applied to the upper and lower fabric 1 by the heat of the heat bonding roller is melted by heat to fuse the insect screen and the radiation layer, thereby forming a strong dust proof mesh. That is, the dustproof layer radiated between the two polyester insect screens is firmly attached to the final complete dustproof screen.

The completed anti-vibration net is wound by the winder 40 and packaged in a roll form, so that it can be processed to a required length and width. This embodiment presents an example of the material constituting the vibration-proof net. As the insect-proof net constituting the vibration-proof net, various types other than metal materials, that is, polyester, polyethylene, polypropylene, nylon, natural cotton yarn, artificial silk yarn, etc. Any material that can make up the material can be used, and the nano-radiated material is Polyvinylidene Fluoride (PVdF), Polyvinyl Alcohol (PVA), Polyethylene Oxide (PEO), Polyurethane (PU/TPU), Polyaniline, including nylon of this embodiment.
