Manufacturing method of air circulation type fine dust dustproof net using nanofiber

Abstract

According to the problem to be solved by the present invention, a method for manufacturing a fine dust proof mesh using a nano-fiber coats a mesh to which a nano-fiber is bonded, with a resin by using a special method so as to prevent detachment and damage of the nano-fiber and remarkably reduce a thickness and a weight of a mesh in comparison with an existing product, and enables manufacturing of a fine dust proof mesh having excellent visibility and air permeability.

Description

[0001] technology area [0002] The invention relates to a method for manufacturing a dust-proof net, and in more detail, relates to a method for manufacturing a dust-proof net that can block fine dust and prevent nanofibers from being damaged by external friction or impact. Background technique [0003] In general, for mesh-like fiber products, in order to block insects and other pests, mesh-like products made of various materials are fixed to door and window frames or used in the form of roller blinds, but such products cannot block fine particles that have recently become a serious environmental problem. dust. [0004] Although it is also possible to use non-woven fabrics such as melt-blown non-woven fabrics for dust-proof nets for blocking fine dust, it is difficult to block ultra-fine dust below PM (Particulate Meter) 2.5. In addition, since the visibility outside the window needs to be ensured in order to be installed on the window, the conventional nonwoven fabric for ...

Problems solved by technology

[0005] However, nanofibers are fibers with a diameter of tens to hundreds of nanometers, which are mainly produced by electrospinning. When nanofibers are coated on the net, they cannot be attached to the net due to their lack of adhesiveness, and the filtering function cannot be maintained. The problem

[0006] In addition, since the physical strength of nanofibers is low, they are easily damaged by external impact or friction, causing the performance of products to deteriorate.

That is, there is a problem that it is difficult to use the nanofiber coated net in a place where external force often acts due to poor durability

[0007] In order to solve the durability problem of nanofibers, some manufacturers combine thin mesh products on nanofibers. This manufacturing method not only leads to the increase of thickness and weight of the product, but also increases the cost of raw materials. High potential for damage to nanofibers

In addition, when the mesh-integrated product is used for a long time, there will be problems such as partial peeling of the protective mesh, damage to the appearance of the product, and a decrease in the protective function of the nanofiber, so it cannot be used freely.
