Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Referring to the attached figure 1, the high-efficiency filtering meltblown fabric comprises a base layer 1 and a filtering layer 2, wherein the filtering layer 2 is arranged on the outer side of the base layer 1 and has a cellular structure with air holes, the base layer 1 is formed by polypropylene superfine fibers through thermal bonding, a chip blocking groove 11 is formed in the surface of the base layer 1, a channel 12 penetrating through the base layer 1 is arranged in the base layer 1, the channel 12 is communicated with the chip blocking groove 11, and the channel 12 is continuously bent in the base layer 1 and is in a lightning shape.

The base layer 1 formed by polypropylene superfine fiber through thermal bonding has good filtering property, shielding property, heat insulation property and oil absorption property, because the fineness of polypropylene fiber is lower, thereby the high-efficiency filtering melt-blown fabric has larger area and higher porosity, the filter layer 2 is of a honeycomb structure with air holes, impurities such as larger dust in the air are isolated outside, the chip blocking groove 11 can store the external impurities in the chip blocking groove 11, the channel 12 can ensure that the air permeability of the high-efficiency filtering melt-blown fabric is better, impurities and particles can be blocked outside, the channel 12 is continuously bent twice in the middle, the shape of the channel 12 is known from the attached drawing 1, the channel 12 is in a lightning shape, the smaller particle impurities which can pass through the channel 12 can be remained in the channel 12 through the lightning shape, and the filtering effect is further increased.
