The melt-blown fiber sheet is a melt-blown fiber sheet made of fine denier fibers produced by one-way melt blowing. The fibers constituting such a melt-blown fiber sheet need to have a single fiber diameter in the range of 0.1 to 5.0 μm. That is, if the diameter is less than 0.1 μm, the strength of the single fibers will be low and the subsequent handling properties will be poor. On the other hand, if the thickness exceeds 5.0μ, excellent filter performance cannot be obtained and this is not preferred. Furthermore, the average apparent density of melt-blown fibers is 0.05~
A range of 0.03 g/cd is preferable, that is, if it is less than 0.05 g/ca, it becomes difficult to uniformly form an electret. Also, 0.30g/
If it exceeds c++7, problems such as breakage may occur when molding into a mass mold, which is undesirable. The basis weight of melt-blown fiber sheets and non-woven sheets is not particularly limited, but in order to obtain excellent mask performance, it should be 10 to 100 g/
Preferably it is rrf.

方法である。A known method can be used to convert a nonwoven sheet into an electret. For example, heating a nonwoven sheet to around its softening temperature,
Thermal electrets obtained by cooling while applying a direct current high voltage, electroelectrets that apply corona discharge or pulsed high voltage to the surface of the nonwoven sheet, and radioelectrets that irradiate gamma rays or electron beams can be used. A method of performing corona discharge using a grounded electrode having a porous surface (Japanese Patent Application No. 61-296533) is also a preferred method.

There are also bulky non-woven sheets. Such a bulky nonwoven sheet preferably has an air permeability of 30 cc/cd/sec or more and a thickness of 0.1 mm or more. That is, the air permeability is less than 30cc/cJ/see,
A nonwoven sheet with a thickness of less than 0.1 mm is undesirable because it impairs the breathability of the mask. Furthermore, such a bulky nonwoven sheet preferably has an elongation at break of 100% or more at 150°C. . That is, if the elongation at break at 150° C. is less than 100%, moldability deteriorates and it becomes impossible to mold into a mask mold, which is not preferable.
