Anti-haze light-transmitting stealth gauze and preparation method

Abstract

The invention relates to the field of filter materials and provides an anti-haze light-transmitting stealth gauze. The anti-haze light-transmitting stealth gauze comprises a gauze and a nanofiber layer supported on the surface of the gauze, wherein the nanofiber layer is formed by supporting a nanofiber spinning solution on the surface of the gauze through electrostatic assisted jet spinning. Theanti-haze light-transmitting stealth gauze has high light transmittance, good ventilation and efficient filter performance simultaneously, PM2.5 and PM10 are filtered efficiently, light transmittanceand ventilation of the gauze are guaranteed, and the stealth gauze integrates air filtering, light transmittance and ventilation.

Description

technical field [0001] The invention relates to the field of filter materials, in particular to an anti-fog and haze light-transmitting invisible gauze and a preparation method thereof. Background technique [0002] With the development of the economy, the environment is becoming more and more polluted. According to the Global Disease Survey Index, in 2010 alone, the number of deaths caused by smog in the world was as high as 3.3 million. If it is not curbed, this number will double in 2050. times. Taking Beijing as an example, there were 193 days in 2014, when the concentration of outdoor smog exceeded my country’s national standard (75 μg / m 3 ), the residents are forced to close the doors and windows to reduce the hazards of smog, but the closed doors and windows cause the average indoor air change rate of the residents to increase from 2.34h -1 Drop to 0.27~0.35h -1 , far below the national standard of our country. At present, masks and air purifiers are commonly used...

AI Technical Summary

Problems solved by technology

At present, masks and air purifiers are commonly used to filter smog. Masks are often used for outdoor activities, and indoor smog protection mainly depends on air purifiers. However, they have the disadvantages of high price and high energy consumption, so the development of smog It is very necessary for the screen window with haze filtering function to be sufficient, which can meet the needs of filtering haze and indoor ventilation at the same time

[0003] The common materials with haze filtering function on the market mostly focus on reducing the yarn diameter, increasing the fabric density, or increasing the thickness of the material. The haze filtering effect is achieved at the expense of the light transmission performance of the material, which is far from being satisfactory as an air filter. Dual requirements for light transmittance and filtering effect when using filter gauze material
