Description

Health mask {Health mask}

The present invention relates to a health mask, and more particularly, to a high-quality health mask that is easier to breathe using a nonwoven fabric having strength, has a dust collection rate of 94% or more, and does not contain pigments and foreign substances.

In general, masks can be divided into household products (manufactured products) and quasi-drug masks. Among them, industrial dust masks and surgical masks classified as quasi-drugs, and health masks are dust-collecting efficiency, facial inhalation resistance, and leakage. It is included in the subject of certification or approval for which performance standards and test methods such as rate are established.

Health masks are used for the purpose of protecting the respiratory tract from harmful particulate matter or infectious agents as they have a particle blocking function. They have a fine dust blocking function and a filter function. Health masks are classified into KF80, KF94, and KF99 according to their fine particle blocking performance. Here, KF stands for Korea Filter, and'KF80' can filter out more than 80% of fine particles with an average size of 0.6㎛, and'KF94' and'KF99' refer to 94% and 99% of particles with an average size of 0.4㎛, respectively. It can filter out abnormalities.

In addition, health masks are divided into foldable and cup-type depending on their shape. In the folding-type, the side with the nose support (fixed core) attached to the top and close to the nose, and the head strap is attached to the ear, and the cup-type is the nose and chin. After matching it to the face to wrap it, use it by fixing it with a string.

Conventional health masks are mostly composed of microfibers or HEPA filters by laminating products woven using cotton or synthetic fibers in two or three layers.In order to impart antibacterial properties, inorganic antibacterial particles are coated or silver nanoparticles are applied to the fiber surface. Was prepared by depositing on.

The foldable mask disclosed in Korean Patent Application Publication No. 10-2011-0124937 includes a main body, an upper barrier layer in which a surface layer and an inner layer are overlapped, a lower barrier layer in which a surface layer and an inner layer are overlapped, an upper fold part, a lower fold part, and a fixed It consists of a string adjusting device, a fixed strap adjusting device cover, and a nose shape adjusting member.

In addition, the multi-layered non-woven fabric sheet disclosed in Publication No. 10-2015-0117113 and the non-woven fabric mask using the same include a cellulose sheet layer having a thickness of 0.01 to 1 mm, a polypropylene layer having a thickness of 0.01 to 2 mm, and , A cellulose sheet layer having a thickness of 0.01 to 1 mm is sequentially stacked and fixed by water flow bonding.

Non-woven fabrics are fabrics made by bonding or tangling fibers without going through a woven process, by mechanical operation, or by heat bonding or using chemicals, which imparts morphological stability only by the bonding force between the fibers. Non-woven fabric manufacturing methods are largely classified into dry method and wet method according to the method of manufacturing non-woven fabric, and are divided into mechanical bonding method, needle punching method, and spinning method, melt blown method, and spun bonding method, according to the means of imparting shape stability to the manufactured non-woven fabric. . Among them, the strength of the needle punched nonwoven fabric is influenced by the frictional resistance of the paralleled fibers and the entanglement of the fibers arranged in the vertical direction in the needling process, not the chemical adhesion between the fibers, and the density of the nonwoven fabric by needling during the manufacturing process. And the thickness will change.

Conventional health masks contain foreign substances such as pigments in the non-woven fabric, so that product defects are easy to occur, and the blocking efficiency of fine dust is low, and it is difficult to breathe, so it can be used for a long time due to discomfort caused by fog or moisture. There is a difficult problem.

The present invention was conceived to solve the above problems, and the object of the present invention is to use a nonwoven fabric with strength to facilitate breathing, to have a dust collection rate of 94% or more, and to provide high-quality health care without pigments and foreign substances. It is to provide a dragon mask.

This embodiment discloses a high-quality folding health mask.

The disclosed health mask includes a body part for protecting the respiratory tract by being worn on the mouth part, a nose cover part for blocking the suction of outside air to the nose part when worn by being sewn on the rear upper side of the body part, and the body part It includes a chin rest portion for blocking the suction of outside air to the chin portion when worn by one end of which is sewn on the lower rear side, and a pair of earring straps mounted on both ends of the body portion to hang the body portion on the ears.

The body portion includes an outer skin layer made of a fabric, a support layer made of a nonwoven fabric having a density of 55 to 65 g/m2, a filter layer made of a nonwoven fabric having a density of 25 to 35 g/m2, and an inner skin layer in contact with the skin It has a multi-layered structure.

The nose cover portion may include a nose support that maintains a shape so as to be in close contact with the wearer's nose.

The health mask according to the embodiment of the present invention is worn to block external air from flowing directly into the respiratory tract without passing through a filter through the nose or chin, and breathing is good while the quadruple filter unit collects more than 94% of fine dust. Therefore, it has a convenient effect to wear.

In addition, the health mask according to an embodiment of the present invention can guarantee high quality because no pigment is detected as in the certified test report.
