However, in the case of a HEPA class high efficiency filter material, It is possible to manufacture by variously applying various factors such as air permeability, distribution of pores and kind of polymer. Glass fibers with shape stability and price competitiveness are currently used as conventional high-efficiency filter media, but conventional glass fibers can obtain high-efficiency filter media. However, since there are environmental problems and material change problems due to aging changes, There is no situation. It is difficult to obtain a filtration efficiency of 95% or more in other nonwoven fabric manufacturing methods, and it has been difficult to obtain a high efficiency filter medium because it has various potential efficiency inhibiting factors such as fiber diameter, web homogenity, and uniformity of porosity.

The rubber-like disc-shaped medium 58 facilitates breathing when the user exhales, while preventing intake of contaminated air as intake air.

The sound of the flute 70 can be adjusted by using the principle that the length of the string (string length) becomes longer, and the frequency of the sound is lowered. For example, if the first sound is 'Do', the sound that reduces the length of the string by 2/3 can produce a 'brush' that is 5 degrees higher than 'Do'.

The height of the sound according to the length of the string can be controlled by making the length of the cylindrical shape of the flute constant and controlling the length of the hollow tube 71 included therein. In order to control the sound of such a flute 70, a flicky kit storing only the flute 70 may be produced.

5 is a perspective view showing the appearance of an exchangeable filter attached to a mask according to an embodiment of the present invention.

Referring to FIG. 5, in the case of the exchangeable filter 40, the mask 100 may be attached to the mask 100 through a velcro 30 inserted in the mask 100, or may be detached with a very small force. The process of attaching the exchangeable filter 40 through the Velcro 30 will be described in detail as follows.

The attachment of the so-called exchangeable filter 40 can use a velcro fusion method.

The dictionary definition of fusion is that two or more are melted and become one.

If 'A + B' is complex, the fusion is A + B = C. In other words, it is the convergence that two or more meet and create a completely new thing. It is like organizing biology in botany and zoology. Is the reorganization of the curriculum by extracting some common factors in terms of content and nature while maintaining the quality of the curriculum.

One example of fusion in real life is Velcro, which is called "Squeaky". Velcro was developed by Swiss electrician Georges de Meco, and the Velcro 30 is now being used in a variety of fields such as clothes, bags, shoes, and the like.

And there are clothes made of webs. Compared to steel of the same weight, twenty times as high as silk spun silk is not only very stretchy, but also because it is four times stronger than Kevlar fiber made by DuPont. Genetic engineering has been applied to mass production of webs. This fusion of knowledge and collaboration in various fields such as biology, chemistry, and design is what creates new things that have never existed in the world.

The Velcro 30 is placed on the front side of the velcro end forming portion 111a for attaching the replaceable filter 40 of the lower mold 100A of the mask 100 by the method of Velcro Fusion, 100B may be formed in the mask 100 by being inserting in a fixed manner through the velcro end insertion hole forming portions 111b of the first and second end portions 100A and 100B.

At this time, since the replaceable filter 40 provides a replaceable structure in the filter-exchange type general-purpose synthetic resin mask of the velcro inserting type comprising the slit guide portion 20a of the mask 100, it can be reused after long-term storage , And can have a sanitary effect for filter insertion or replacement.

6 is an exploded perspective view showing the structure of a replaceable filter in a mask including a moisture discharge valve according to an embodiment of the present invention.

6, an exchangeable filter 40 for use in a mask 100 including a moisture drain valve according to an embodiment of the present invention includes an exchangeable filter 40 that is attached to the Velcro 30 of the face of the mask 100, A lylex 42 made of a polyester material and a non-woven charging filter made of acrylic material adhering to the rear surface of the lylex, that is, the electrostatic filter 44 made of acrylic material, , And can block total suspended particles having a particle size of 10 mu m or more.

Dust is one of the particulate matter that floats or falls down in the atmosphere. It is usually called a descending dust, which has a particle size range of 0.1 to 500 탆 and is heavy and liable to sediment depending on the particle size. The electrostatic filter 44 described above can function to block total floating dust having a rather large particle size. Although the total floating dust does not adversely affect the human body due to difficulty in sucking through the nose through the nose, when the minute dust (2.5 mu m) smaller than the total floating dust is combined due to the electrostatic property to generate total suspended dust It can be said that a primary cut-off is necessary.

The fine dust that has passed through the electrostatic filter 44 may be blocked by a polypropylene ultra-static micro filter 46 that blocks dust and harmful substances having a particle size of 2.5 μm or less.

The ultra-electrostatic micro-filter 46 may be manufactured by a melt blown process.

The meltblown composite spinning method has a property of improving the filtration efficiency and improving the differential pressure by producing a nonwoven fabric by meltblown composite spinning with two-component polymers having different melting points, and then performing heat shrinkage treatment.

The meltblown composite spinning method is a method in which a first thermoplastic polymer (1A) having a fiber forming ability and a second thermoplastic polymer (1B) having a fiber forming ability and having a melting point lower than the melting point of the first thermoplastic polymer The meltblown composite melt can be melted through a spinning nozzle (s110). The reason why two polymers having different melting points are used is to express the vulcanization due to the contraction difference of the two-component polymer during the heat shrinking process after the formation of the web. It is a polymer which can be produced by fiber- Although not particularly limited, the first thermoplastic polymer and the second thermoplastic polymer should have a combination of melting points different from each other. For example, if the first thermoplastic polymer is polypropylene, the second thermoplastic polymer may be polyethylene, polyester, polyamide, polybutylene terephthalate (PBT) or thermoplastic polyurethane (TPU) having a lower melting point than the first thermoplastic polymer.

It goes without saying that inorganic and organic additives may be added to the polymer of the present invention in order to control the spinning viscosity and improve the filtration efficiency and durability of the exchangeable filter 40. Since the kinds of these additives are well known, they are not described here.

Fig. 7 is a view showing a meltblown composite spinning device.

Referring to FIG. 7, it is possible to manufacture nano-sized microfibers at a level of 1 micro (m) through fine nozzles such as 35 holes, 50 holes and 100 holes per inch according to the spinning conditions of the meltblown composite spinning .

The cross section of the composite spinning fiber by the melt blown composite spinning is not particularly limited, and both inner and outer side and side by side types are available.

The composite yarn 3 produced by the meltblown composite spinning is fed into the air by the cold air supply device 2 at a temperature lower than the glass transition temperature of the second thermoplastic polymer 1B before reaching the collector 4 And c120) curing the melt-blended composite spinning fiber (3). By this process, the composite spinning fiber 3 can be cooled and cured to improve its shape stability. Here, although the low-temperature air current is brought into contact with the spinning fiber, since the melt blown composite spinning fiber 3 drops down at a high speed, the curing here is not complete curing, and about 10 to 20% The composite fibers are collected in the lower collector 4 together with the fibers that are cured as they are, and the entire composite fibers are evolved into a fibrous web (s130). The temperature of the cooling air stream varies depending on the kind of the polymer to be used, the discharge speed, etc., but is about 5 to 25.

In the production of the mask 100 including the moisture discharge valve 50 according to an embodiment of the present invention, the meltblown method may be used, and the second thermoplastic polymer 1B may be applied to the formed web, (S140) at a temperature between the melting point of the glass transition temperature and the glass transition temperature. By this process, a shrinkage difference between the first thermoplastic polymer (1A) and the second thermoplastic polymer (1B) is generated, thereby increasing the bulky property in the web. The heat treatment temperature should be a temperature between the melting point of the second thermoplastic polymer having a low melting point and the glass transition temperature although it depends on the moving speed of the web or the type of the polymer used. For a commonly used polymer having a fiber-forming ability, the heat treatment temperature may be 90 to 130 ° C.

Further, in the case of the composite spinning fiber 3 subjected to the melt-blending treatment of the present invention, electro charging may be performed by a separate process (s150). In the electrostatic treatment, a web is formed by using an electrostatic device 8 that supplies charges of positive and negative charges. Charges are charged on the surface of the web before being wound on the winder 9, 40 can be made to perform the function of adsorbing fine dust in the air to be used. The voltage used is (+) 20-40kV, (-) 15-35kV. Most of the replaceable filters 40 except for the clean room of the semiconductor or electronic industry, in addition to this method, add an additive having a high dielectric constant to the polymer to improve the electrostatic property.

In addition, the filter including the moisture discharge valve according to an embodiment of the present invention may include a spunbonded nonwoven fabric 48 capable of minimizing a high air permeability, a liquid defense force, and an uncomfortable feeling when the user touches the body.

Also, although not described in detail, the moisture discharge valve according to an embodiment of the present invention may include a disc-shaped medium (not shown) made of rubber. The disk type medium is configured such that it can be mounted on the fixing mechanism 52 of the moisture discharge valve 50. In manufacturing the disk type medium, the fixing mechanism 52 is attached during the injection molding process, Can be performed. The fixing mechanism (52) may be provided with a flange at a portion thereof abutting the user's mouth in order to seat the disk-type medium on the fixing mechanism.

After the disk type medium is loaded through the flange, the disk type medium can be fixed by rotating the stopping mechanism. In the case of the mask 100 in which the moisture discharge valve 50 is coupled, it is possible to easily replace the disc type medium when it is inadvertently broken over time or in use, thereby securing the function as the moisture discharge valve 50 .
