Window screen mesh, preparation method and application thereof

Abstract

The invention relates to a window screen, a preparation method and application thereof, in particular to a novel anti-fog and haze screen net with a three-dimensional structure. The screen window net includes an upper net, at least one middle net and a lower net, wherein the upper net and the lower net are plain weave or twill weave, and the middle net is honeycomb weaved; the middle net is respectively connected with the upper net The net and the lower net are braided and connected to each other, and intermediate interlayer structures are respectively formed between the upper net and the middle net and between the lower net and the middle net. The window screen net of the present invention has good barrier efficiency for fine particles such as PM2.5, and at the same time, due to the three-layer three-dimensional structure, the screen window net has a relatively high porosity and has good ventilation performance.

Description

technical field [0001] The invention relates to a window screen, a preparation method and an application thereof, in particular to a novel screen net with a three-dimensional structure, a preparation method of the screen net and an application of the screen net to products that need to block fine particles. Background technique [0002] Among the currently used screen nets, most of them use single-layer plain weave structure PVC-coated glass fiber nets, but their disadvantages are: due to the large mesh holes, they have no barrier efficiency for fine particles such as PM2.5. In order to increase (improve) the barrier efficiency of the screen net, some people adopt the method of electrostatically processing the screen net after electret or covering the microporous film on the basis of the existing screen net. However, the former is difficult to maintain the barrier effect for a long time due to the fast decay of the electrostatic electret; the latter seriously affects the ven...

[0002] Among the currently used screen nets, most of them use single-layer plain weave structure PVC-coated glass fiber nets, but their disadvantages are: due to the large mesh holes, they have no barrier efficiency for fine particles such as PM2.5

However, the former is difficult to maintain the barrier effect for a long time due to the rapid decay of the electrostatic electret; the latter seriously affects the ventilation performance because the microporous membrane is basically airtight.
