Problems solved by technology

There are also many disadvantages, such as (1) a part of the warp and a part of the weft do not form intersections during weaving, and the structure is relatively loose; (2) the warp and weft are not bonded at the intersection, when filtering air When washing and cleaning, the warp or weft will shift, and the mesh size will be changed accordingly,

preparation example Construction

[0041] The method for preparing the air filter of the present invention includes:

[0042] (1) Knitting: Put the sheath-core composite hot-melt bonding wire on the braiding machine along the radial and weft directions. The angle between the radial wire and the weft wire is 30°~90°, and then the warp wire and the weft wire are Interlace in a staggered manner, so that the warp and weft yarns touch at the intersection and weave into a net;

[0043] (2) Heating bonding: heating the knitted net at a temperature of 20°C to 40°C higher than the melting temperature of the skin material and 20°C lower than the melting temperature of the core material to make the warp and weft skin materials Melt and bond at the point of contact.

[0044] In the method of the present invention, the weaving machine can be a conventional weaving machine in the industry, preferably a plain weaving machine or a twill weaving machine.

[0045] The outer layer (skin) of the bonding wire is a low melting point pla...

Abstract

The invention relates to an air filter screen, a preparation method and application thereof. The air filter screen is produced by knitting composite heat melting adhesive wire of sheath-core type along radial and latitudinal directions; the filter screen is flat; the angle formed by the radial wire and the latitudinal wire is 30-90 degrees; each radial wire and each latitudinal wire are contacted and adhered at the crossing points; the melting point of the core layer material of the sheath-core type composite heat melting adhesive wire is 40 DEG C or higher than the melting point of the sheath material. The preparation method of the filter screen comprises the following steps: net knitting and heating adhesion; the temperature of heating adhesion is 20-40 DEG C higher than the melting temperature of the sheath material, but 20 DEG C or more lower than the temperature of the core layer material. The air filter screen can be applied to a household air-conditioner, an air purifier device or an air refresher. The air filter screen has firm structure; when air filtering and cleaning are carried out, the radial and latitudinal wires can not displace, which enables the filtering efficiency of the filter screen to be stable and air resistance distribution to be even.

Description

Technical field [0001] The invention relates to an air filter screen, in particular to an air filter screen with a stable structure. Background technique [0002] Household air conditioners and air purifiers are equipped with air filters to filter out the dust in the air and provide people with clean air. Nowadays, the filters in household air conditioners and air purifiers are filters organized with a honeycomb structure. The advantages of the structured filter are: (1) Large dust holding capacity; (2) Low resistance. There are also many shortcomings. For example, (1) a part of the warp and a part of the weft do not form a cross when weaving, and the structure is relatively loose; (2) the warp and the weft are not bonded at the intersection point, when the air is filtered During cleaning and cleaning, the warp or weft will shift, and the mesh size will be changed accordingly, resulting in unstable filtration efficiency of the filter and uneven air resistance distribution; (3) Th...
