Abstract
The invention discloses a bubble-point type air filtering gauze for doors and windows. The bubble-point type air filtering gauze is formed by compounding of three layers, i.e., a planar framework material layer, a high-efficiency low-resistance air filtering material layer and a bubble-point framework material layer and has a sandwich structure, wherein the upper layer is the planar framework material layer, the middle layer is the high-efficiency low-resistance air filtering material layer and the lower layer is the bubble-point framework material layer. The bubble-point type air filtering gauze has high strength, high stiffness, small air resistance and high air filtering efficiency, is capable of highly efficiently intercepting fine particles like PM2.5 without influencing ventilation, has a plurality of functions like energy conservation, noise prevention, heat insulation, purification and mosquito prevention, can replace traditional screen windows and doors, etc., and introduces outdoor contaminated air into a room after filtering to maintain indoor ventilation.
Description
Technical field
The present invention relates to door and window yarn production technical field, more particularly to a kind of bubble point formula door and window air filtration yarn.
Background technology
With our quick Development of China's Urbanization, industry and expanding economies, atmospheric pollution is also on the rise（Particularly
The fine particles such as PM2.5 pollute）, especially into 2013 since, mainly by PM2.5 pollution caused by haze weather attack me
The important cities such as state most area of east, Beijing, Shanghai are deeply hurt, and people's health is severely impacted.It is outdoor tight
The haze weather of weight makes ordinary people open a window ventilation, and indoor stale air can make the person uncomfortable, meeting for a long time
The body of people is caused to have a strong impact on.
Existing screen window, screen door, yarn have cotton cloth, woven dacron etc. by material point, generally with fine and closely woven mesh, can stop
The entrance of the insecticides such as mosquito, fly.Conventional yarn does not affect air circulation, but as mesh is larger, which cannot be by PM2.5 etc.
Fine particle is isolated outside, in today that environment goes from bad to worse, and haze weather still can only rely on and close the doors and windows to protect, it is impossible to
Windowing ventilation, if yarn will can be done the similar mask material that the fine particles such as PM2.5 are isolated outside, air drag is excessive,
It is unable to reach ventilation effect.
The content of the invention
It is an object of the invention to provide a kind of bubble point formula door and window air filtration yarn, is nonwoven cloth material, for screen window,
The making of screen door, has high intensity, high stiffness, and air drag is little, and air filter efficiency is high, can be high to fine particles such as PM2.5
Effect is intercepted, and does not affect air circulation, with the several functions such as energy-conservation, its anti-noise, heat-insulated, purification, mosquito proof, alternative tradition
Screen window, screen door, will introduce indoor after the air filtration of outdoor pollution, keep room air circulation.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of bubble point formula door and window air filtration yarn, the air filtration yarn are by plane framework material layer, efficient low-resistance
Three layers of air filting material layer and bubble point framework material layer are composited, and with sandwich structure, upper strata is plane framework material
Layer, middle is efficient low-resistance air filting material layer, and lower floor is bubble point framework material layer.
The present invention is reformed to the window screening of traditional monolayer net checkerwork cell, door yarn, is developed first new compound
Air filtration yarn, in today that environment goes from bad to worse, brings airfiltering concept into traditional window screening, door yarn product, gives
The function of the new filter small particles pollutant of traditional window screening, door yarn.Two-layer is the Planar Bone of inventor's specific development up and down
Frame material layer, bubble point framework material layer, carry out coarse filtration, coordinate the efficient low-resistance air filting material layer essence in intermediate layer to filter,
So combine, air drag is little, air filter efficiency is high, and the fine particles such as PM2.5, dust, pollen efficiently can be intercepted, and not
Affect air circulation.With the several functions such as energy-conservation, its anti-noise, heat-insulated, purification, mosquito proof, alternative traditional screen window, yarn
Door, will introduce indoor, keeps room air circulation after the air filtration of outdoor pollution.Present configuration is simple, low production cost.
Plane framework material layer intensity is high, plays skeleton function.Bubble point framework material layer its bubble point and efficient low-resistance air mistake for projecting
Filter material bed of material point is contacted, and forms numerous tiny still air passages, can preferably be accommodated dust, be improved sound insulation, warming, energy-conservation
Effect.
