Description

 TECHNICAL FIELD [0001] The present invention relates to a nano-damping network for blocking ultrafine dusts,

The present invention relates to an ultrafine dust-screening screening net and a method of manufacturing the same, which is fabricated in the form of a screen for insect protection and dustproofing for general windows, (Fabric 1), an ultrafine dust-proofing net having a pore size of 0.1 to 100 μm was formed on the fabric 1 (nylon 2) in order to shield ultrafine dust by spun nylon resin in the form of nanofiber, A nano-dust-proofing layer capable of blocking ultrafine dust produced by hot melt resin so that the nano dust-proof layer can be firmly fixed to the polyester fabric mesh by passing another fabric 1 over the nano-radiation surface of the fabric 2, .

The nano-dazzling network manufactured by the present invention can be used in a manner that it is sandwiched by a window frame instead of a conventional screen inspecting net attached to a window frame or a door frame, or may have a function of blocking fine dust in addition to the existing screen inspecting net. The present invention provides a nanodisperse network for blocking ultrafine dust that can block the inflow of ultrafine dust, which is perceived as a main cause of diseases of the engine and respiratory system, to the utmost.

Generally, a window of a residential building such as a house or an apartment is provided with a mesh screen insect net which can block insects such as mosquitoes and flies and is capable of ventilation. The material of this insect screen is widely used for various synthetic materials such as nylon and polyester, thin metal nets such as aluminum and stainless steel, and recently, various products using glass fiber. However, recently, the frequency of harmful fine dust that can flow into the room through the insect screen having a conventional insect-proofing function has become frequent, and the fear of respiratory system disease due to ultrafine dust has increased, It is a fact that it is reluctant to open windows to ventilate. Therefore, it is inevitable to develop a new insecticide / dustproof network that can block harmful ultrafine dust as well as insect blocking which is a function of the existing insect screening network.

The present invention relates to an existing screening net that functions to block harmful pests by attaching to window frames of residential buildings, and nano-sized dust-free chains are formed by spinning nanofibers so that ultrafine dusts, By firmly fixing it on the surface of the insecticide network, it is a filtering mesh for windows which has not only insecticidal function but also function to block fine dust, but has air permeability and liquid water, that is, And to provide usable nanoinduced waveguides.

In order to solve the above-mentioned problems, the present invention provides a method for manufacturing a woven fabric comprising the steps of: applying a hot-melt resin on one surface of a mesh-type insect-control fabric formed of a polyester yarn in the form of a dot; spinning the nylon resin in the form of a nanofiber; An ultrafine dust-free network with a pore size of 0.1 to 100 μm was formed to block the dust. Then, another hot melt resin coated with hot melt resin is dot-laid on the nano radiating surface, and the hot melt resin coated on the dot is melted and pressed by the hot adhesive roller by passing the hot melt resin through the hot rolling roller, The present invention provides a nanodisperse network for blocking ultrafine dusts, which is manufactured so that the nano network can be firmly fixed on a polyester screening net.

The nano-damping network of the present invention can replace an insect screen installed in existing residential facilities, education facilities, business facilities, and also can open windows at all times to enable natural ventilation, It effectively blocks the harmful particles such as fine dust and so on, thereby maintaining a pleasant indoor environment. In addition, it is not necessary to close the window even in case of rainy weather because the permeation gap of the nano-dust-proof net can be finely cut off and rainwater can be blocked. Even if the dust-proofing network is contaminated by the blocked dust, water is sprayed on the surface of the dust- . It is composed of flexible synthetic fiber yarn, so it can be easily cut to the required size and used for necessary applications, so it can be used in various fields such as windscreen wiper, air filter for air conditioner and dust mask filter.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

In order to manufacture the nano-damping network to be provided in the present invention, an insect net composed of a polyester yarn is manufactured in one step, and hot melt resin is applied on one side of the insect control net in dot form to prepare an insect control net (fabric 1) do. In step 2, nylon resin is spin-coated in the form of nanofiber with nano spinning device (20) on the face coated with hot melt of fabric 1. At this time, the radiation amount of the nanofiber per unit area (1 m 2) is suitably about 1 to 10 g, and the optimum result is about 1 to 3 g. In the third step, another insect control net (fabric 1) is laid on the radiated nano-damping network so that the nano-sized vibration-damping net applied to the screening cloth 1 (fabric 1) can be fixed to the surface of the fabric. The hot melt resin coated on the upper and lower fabrics 1 is melted by heat to melt the insect control net and the nano spinning layer by the heat of the heat adhesive roller, thereby forming a solid nano dust-free network. That is, the nano-radiated dustproof layer is firmly adhered between the two polyester screen screens to finally complete the complete nano-dust-screening network. The completed vibration damping net is wound by a winder 40 and packed in a roll form, and can be machined to a required length and width. The present embodiment shows an example of a material constituting the nano-dwindling network. As an insect-proofing network constituting the nano-dwelling network, various kinds of inspecting nets other than metal materials such as polyester, polyethylene, polypropylene, nylon, natural cotton yarn, (PVDF), Polyvinyl Alcohol (PVA), Polyethylene Oxide (PEO), Polyurethane (PU / TPU), and the like, as well as the nylon of this embodiment.
