<Related Art> As a dust collecting filter used in an electric vacuum cleaner, there is a dust collecting filter made of pulp, which collects dust in the dust collecting filter and discards the dust together with a paper bag. A disposable type using a paper bag dust filter does not require the trouble of cleaning the filter, and has no inconvenience such as dust scattering when throwing away trash, and is a preferred method as a filter method for a vacuum cleaner. However, the dust filter of the disposable paper bag is clogged before dust sufficiently accumulates, and the suction ability of the vacuum cleaner is reduced. Further, the air permeability of the dust filter is lower than the collection efficiency, and the suction ability of the vacuum cleaner is reduced. As the paper bag dust filter, there are air-permeable single-layer paper and multilayer paper generally called Japanese paper. Since this type of material causes clogging soon due to the attachment of dust,
There are drawbacks that the amount of dust collected is small and the air permeability is low. Therefore, a dust collecting filter which is hardly clogged and has a low pressure loss is desired.

<Means for Solving the Problems> The present invention relates to 1. A fibrous sheet having an air permeability of 50 to 100 cc / cm 2 / sec on one side in a melt-blown fiber assembly formed into an electret having a single fiber diameter of 1 to 5 μm. Is a dust collecting filter for an electric vacuum cleaner, which is closely adhered so as not to be peeled off, and is treated for insect repellency, bacteria repellency and water repellency.

A method of performing corona discharge using a ground electrode having a porous surface is also a preferable method.

For improving the performance of the electret, polyolefin, polysell, polycarbonate and the like are used for the fiber aggregate, and polyolefin is particularly preferable. Polyolefin resins include polypropylene, ethylene-propylene copolymer, high-density polyethylene, low-density polyethylene, linear low-density polyethylene, ethylene-vinyl acetate copolymer or mixtures thereof, and modified with unsaturated carboxylic acid derivatives And the like. Among the polyolefins, a polypropylene or an ethylene / propylene block copolymer having a high melting point is preferred because the electret has high stability. The form of the fiber aggregate is not particularly limited, and any form may be used, but a nonwoven fabric is preferable. As the production method, for example, a nonwoven fabric can be formed by using the above resin by a melt spinning method such as a melt blow method, a spun bond method, and a flash spinning method.

Polyamide-based, polyolefin-based, fibrous material made of glass or inorganic compound, the form of which is not particularly limited and may be in any form. Things are good. The air permeability of the fibrous sheet ranges from 50 to 100 cc / cm 2 / sec. When it is less than 50 cc / cm 2 / sec, when combined with the fiber aggregate, the air permeability of the vacuum cleaner pack filter becomes low. Although there is no particular upper limit for the air permeability, the upper limit is about 1000 cc / cm 2 / sec in consideration of the strength of the fibrous sheet.

As a method of combining the fiber aggregate and the fibrous sheet,
When a fiber aggregate is formed and wound, it may be wound together with the fibrous sheet, or may be formed while the fiber aggregate is directly laminated on the fibrous sheet. In addition, there is also a method of joining with a partial adhesive or fusion bonding. As the fusion bonding, for example, there is ultrasonic bonding or high frequency bonding. At the time of combining, it is preferable that the two layers are in close contact with each other so as not to be separated.
