Technical Field

The utility model relates to an articles for use technical field spins at home, especially relates to a can adsorb PM 2.5's haze (window) curtain of preventing automatically.

Background

With the gradual realization of social and economic development and urban industrialization, a large number of toxic and harmful particles in automobile exhaust and industrial waste gas emission cause the air quality problem to become one of the main environmental and ecological problems facing people at present. PM2.5 refers to particles with the aerodynamic equivalent diameter less than or equal to 2.5 microns in the environmental air, can be suspended in the air for a long time, is easy to attach toxic and harmful substances, and can cause great influence on the quality of the atmospheric environment and the health of human bodies.

The curtain is a common household textile product, which plays a role in shading light and decorating and beautifying, and is an essential part in the home. However, with the social development, the living standard of people is continuously improved, the traditional decorative shading curtain has single function and low added value, cannot meet the requirement of increasing the living quality of people, has large contact area with air and long service life, and has potential and application prospect as indoor air purification textile fabric.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve present (window) curtain function singleness, the problem that the added value is low provides the haze (window) curtain of preventing that can adsorb PM2.5 automatically, and it has good air purification performance.

In order to solve the technical problem, the utility model provides a prevent haze (window) curtain with can adsorb PM2.5 automatically. The curtain with the function of automatically adsorbing PM2.5 comprises a cloth substrate layer, an adsorption layer positioned on the cloth substrate layer and a plant micron fiber layer positioned on the adsorption layer. The adsorption layer is a layer formed by compounding plant nano fibers and conductive fibers.

Preferably, the main component of the adsorption layer is a composite material formed by plant nano fibers and conductive fibers, and the thickness of the adsorption layer is 1-2 mm.

Preferably, the plant nano-fiber is nano-cellulose with a diameter of 4-100nm, and is staggered to form a network structure with a pore size distribution of 50-300 nm.

The safe voltage refers to a conventional voltage safe to a human body.

Preferably, the plant microfiber layer is made of 1-10 μm diameter microfiber cellulose, with a pore size of 0.5-20 μm and a thickness of 1-2 mm.

Preferably, the fabric base layer is an organic fiber nonwoven fabric, which has excellent physical properties and a certain air permeability and is suitable as a curtain base material.

The utility model has the advantages that: the utility model discloses in the carbon nanotube material of adoption, can closely combine with the network that plant nanofiber formed, the stratiform of formation is fine and close stable. The carbon nano tubes are uniformly distributed in a network formed by the plant nano fibers to form a conductive path, the conductive path covers the whole curtain, and after a certain safe low voltage is applied through an external power supply, the adsorption layer can generate static electricity, so that the function of automatically adsorbing PM2.5 is realized. As the outermost plant micron fibrous layer can prefilter particles in the air, and keep good air permeability, the prefilter effect is achieved, the subsequent filter layers are prevented from being polluted, and the service life of the haze-proof curtain is prolonged. The utility model discloses a plant nanofiber and plant microfiber green, nontoxic no harmful gas discharges, can be safe be used for the house life.
