Description

Anti-haze and anti-bacterial screen window cloth based on multilayer multi-scale plant fibers

Technical Field

The utility model relates to a field is spun at home, especially relates to an antibiotic screen window cloth of haze of preventing based on multilayer multiscale plant fiber

Background

With the economic development level and the urban industrialization level of the Chinese society becoming higher and higher, more and more cities are affected by haze. The emission of industrial waste gas and automobile exhaust causes a large amount of particles of dust, sulfuric acid, nitric acid, organic hydrocarbon and the like to be suspended in the air, so that the atmosphere is turbid, the visual field is blurred, the visibility is deteriorated, and if the horizontal visibility is less than 10000 meters, the visual range obstacle caused by the aerosol system consisting of the non-aqueous components is called haze. The haze contains hundreds of atmospheric chemical particulate matters, and if filtration and purification treatment are not carried out, the atmospheric chemical particulate matters invade respiratory tracts and lung leaves of human bodies along with air when people take no precautions, so that diseases such as respiratory system diseases and cardiovascular system diseases are caused, and the haze is in the environment for a long time, so that the haze can cause great harm to human health.

In view of the great harm of haze to the human body, the problem of haze treatment is not easy to solve. Urban people are in indoor environment for a long time, and indoor air quality is closely related to human health. The window is used as a main way for indoor and outdoor air exchange, and the screen window becomes a main method for isolating indoor and outdoor pollutants. At present, the screen window on the market obtains better ventilation performance due to larger aperture, but can not effectively isolate substances such as dust and other harmful particles in outdoor air, so that the indoor air quality can be worried about.

Meanwhile, some microorganisms and pathogens float in the air, and the air also can cause harm to human health when entering the room, so that the screen window is worthy of paying attention to how to kill various germs in the air besides chemical substances such as harmful particles in the air need to be filtered, but the attention to the antibacterial and bactericidal performance of the screen window on the market is very little at present.

SUMMERY OF THE UTILITY MODEL

The utility model discloses mainly filter to present prior art and prevent the not enough on haze and the antibacterial property, provide a novel screen window cloth, it can be when having higher air permeability, can effectively completely cut off various harmful particles in the outdoor air and exterminate the germ, is showing and is promoting the indoor air quality.

In order to solve the technical problem, the utility model discloses the scheme of taking is: the utility model provides an prevent antibiotic screen window cloth of haze based on multilayer multiscale plant fiber, includes air filter layer and textile fabric stratum basale. The air filtering layer comprises a nano cellulose layer, a silver nano fiber layer and a micron cellulose layer, and is adhered to the base layer of the textile fabric. Wherein the filter layer has splendid filtration and prevents the haze performance, possesses splendid antibacterial property simultaneously.

Preferably, the micro cellulose layer is composed of micro cellulose with the diameter of 1-10 μm, the pore diameter is less than 50 μm, the thickness is 1-5mm, and the micro cellulose layer can effectively block and adsorb particles with larger diameter in air and has better air permeability.

Preferably, the silver nanofiber layer is composed of crossed nano silver wires, the pore diameter is less than 10 μm, and the thickness is 100-500nm, so that silver ions can be released to kill bacteria and viruses in the air.

Preferably, the nanocellulose layer is composed of plant nanocellulose with the diameter of 4-100nm, and the pore diameter of a nanocellulose network formed by staggering the nanocellulose layer is less than 200nm, so that harmful particles in the air can be further isolated.

Preferably, the textile fabric substrate layer is made of organic fiber non-woven fabric, has excellent physical properties, and is suitable for being used as a screen cloth substrate material.

The utility model discloses following beneficial effect has:

the first nano cellulose layer, the second nano cellulose layer and the second micro cellulose layer can realize the maximum adsorption and filtration of dust and harmful particles in the air, and simultaneously ensure better air permeability. Meanwhile, the nano cellulose layer and the micron cellulose layer have better mechanical and physical properties.

And the silver nanofiber layer has excellent antibacterial performance and can effectively kill various microorganisms such as bacteria in the air. From the outer micron cellulose layer, the layer pore diameter gradually reduces to the inner nanometer cellulose layer, so that bacteria are trapped and stopped in the inner nanometer cellulose layer, the contact between the bacteria and the silver nanometer fiber layer is increased, and the antibacterial performance is improved.

Thirdly, the gauze has good mechanical strength, also has certain flexibility and toughness, is not easy to damage and can be used for a long time.

Detailed description of the preferred embodiments

The invention will be further described with reference to the accompanying drawings and specific embodiments:

as shown in fig. 1, the haze-preventing antibacterial gauze window cloth based on the multilayer multi-scale plant fibers comprises an air filter layer 2 and a textile fabric substrate layer 1, wherein the air filter layer 2 comprises a nano cellulose layer 3, a silver nano fiber layer 4 and a micro cellulose layer 5 which are sequentially stacked and arranged above the textile fabric substrate layer 1. The base layer of the textile fabric is made of non-woven fabric, the thickness of a nano cellulose layer formed by interlacing nano cellulose with the diameter of 4-100nm is about 1mm, the nano cellulose layer is adhered to the non-woven fabric, and the nano cellulose layer is tightly combined with the silver nano fiber layer and the micro cellulose layer with the diameter of 1-10 mu m in sequence.
