BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insect control net, and more particularly, to an insect control net capable of blocking fine dust, which can prevent fine dust from entering the room together with insects.

In general, the screening net is a net installed on a window or a door to prevent insects such as flies, mosquitoes and moths from entering the room.

Such insect screens are made of various materials such as synthetic resin such as nylon, glass fiber (glass fiber), metal and the like.

A typical insect screening network is formed by a mesh network in which wires are arranged at regular intervals in the horizontal and vertical directions and a grid of a predetermined size is formed. The through holes formed in the mesh network have such a size that insects or insects do not pass through.

However, the insect screen according to the prior art is unsuitable for blocking yellow dust, pollen, fine dust, etc. smaller than the size of the through hole.

In order to solve such a problem, recently, an environmental screening network capable of blocking fine pollutants such as dust dust has been proposed.

For example, there is a form in which a photocatalyst and a water repellent agent are coated or impregnated in a metal netting, a glass netting or a cloth netting. However, such an environmental screening net can exert an effect to block the penetration of insects, but there is still a limit to removing ultrafine dusts of PM2.5 or less.
