Example Embodiment

[0008] The filter element of the automobile air filter element adopts a non-woven fabric made of 65% polyester fiber and 35% polypropylene fiber. The ratio of polyester to polypropylene fiber can be adjusted according to the needs during application.

[0009] Then use the existing filter element manufacturing technology to make the filter element, that is, the non-woven filter material is folded into shape, and then rubber, plastic or metal is used to make the frame, and the filter material is hot-pressed onto the frame by a hot mold. Filter element. The ratio of the polyester fiber and polypropylene fiber is not limited to the above ratio. Non-woven fabrics made within the range of 55%-70% of polyester fiber and 30%-45% of polypropylene fiber can be used for the filter element.

Abstract

The invention provides the filter element of the air filter device of a car. The filter material adopted by the filter element of the car air filter device is a non-woven fabric which is made of 55%-70% polyester and 30%-45% polypropylene fiber. Compared with the traditional filter material made of wood and pulp, the texture of the filter element of the car air filter device and non-woven fabric filter material provided by the invention is finer and more uniform and can effectively assure the quality of the air entering the internal combustion engine. The breathable pressure difference of the non-woven fabric filter material is 11.5mm Hg, which is nearly 50% less than that of the 22mm Hg of traditional filter material made of wood and pulp, thereby, the efficiency of the internal combustion engine can reach to 30% and saves oil by 20%. The non-woven fabric filter material can be washed by aqueous alkaline and can be repeatedly used, which reduces the use cost of auto owners and effectively saves environmental resources.

Description

technical field [0001] The invention relates to an automobile air filter core. Background technique [0002] The filter materials used in traditional automotive air filters are made of wood and pulp. The filter elements of this filter material have insufficient oil resistance and water resistance, low dust holding rate, and uneven filtration of fine particles in the air. and other characteristics, so that when it is used as an automotive air filter element, a new filter element needs to be replaced every once in a while, which inevitably causes waste and increases the cost of the filter element. Contents of the invention [0003] The invention provides a filter element for an automobile air filter, which can evenly filter fine particles in the air, save fuel, prolong maintenance intervals, and can be used repeatedly to reduce costs. [0004] In order to solve the above-mentioned technical problems, the technical scheme of the present invention is as follows: the filter ma...
