Description

mask {Mask}

The present invention relates to a mask.

Masks are generally sanitary household items that can cover the nose and mouth to block the cold or to prevent inhalation of dust (dust) and droplets in the air.

On the other hand, conventionally, a mask with an integrated filter has been developed to prevent inhalation of dust (dust) and droplets in the air. Even if the efficiency was expressed, there was a problem that it could not be reused after one-time use.

In addition to these dusts in the air, there are countless pathogens such as bacteria, fungi, and viruses that directly harm the human body. Patients who are undergoing treatment are highly likely to become ill due to the penetration of these pathogens. Moreover, pathogens that can be transmitted through influenza or air cannot be prevented with a normal general mask.

Accordingly, antibacterial treatment of the mask body or an antibacterial mask using an antibacterial fabric or the like is also used. However, a mask with a separate antibacterial treatment has a bad smell, and if worn for a long time, it may cause side effects on the skin or decrease antibacterial durability due to washing.

In addition, if the conventional general mask is worn for a long time, the mask is contaminated with the bacteria in the mouth, and the odor in the mouth is not deodorized. also have

On the other hand, in general, silver (Ag) is excellent in sterilization and deodorization action, and the effect of electromagnetic wave or pulse wave blocking is also very excellent. In addition, silver (Ag) is known to have excellent radiation effects of far-infrared rays including negative ions, and also to have excellent antibacterial and antifungal actions. In addition, silver (Ag) is known as one of the essential metals for enhancing immunity in the body. It is known that silver (Ag) ions are easily absorbed into the human body and block the function of enzymes when bacteria or fungi metabolize oxygen, and act as a strong catalyst to kill these pathogens.

Moreover, silver (Ag) has been widely used as an antidote due to its excellent detoxification action, and has been used as a silver spoon or silver tableware in the royal court since ancient times because of its discoloration by neutralizing or adsorbing heavy metals or various harmful components.

As for the efficacy of silver (Ag), it is written in the herbal medicine Gangmok, "When silver is in the body, the five organs are comfortable, the mind and body are stable, and the body is lightened and morale is expelled. It is recorded as "to make it longer." and in Donguibogam, "Silver is effective in the prevention and treatment of mental disorders such as epilepsy and competition, as well as gynecological diseases such as cold and hay fever." It is written that

Due to the efficacy of silver, there has been an attempt to apply silver (Ag) to a mask in the prior art in order to solve the above-mentioned problems.

In particular, as silver (Ag) nano has become an issue in recent years, many products using silver nano have been developed. However, in the case of the mask to which the silver nano is applied, the silver nano is detached from the mask body by the user's breathing or physical stimulation and is inhaled into the user's respiratory tract, and the antibacterial performance of the mask is deteriorated due to poor washing durability.

Accordingly, the mask has excellent filtration efficiency, can be reused only by replacing the functional media, and has a low moisture absorption rate, which can prevent moisture due to the user's breathing from remaining in the mask body, and It can fundamentally prevent the occurrence of bacteria and re-absorption of the proliferated bacteria, and it has excellent antibacterial performance, washing durability and elasticity, and exhibits the effect of maintaining antibacterial performance and washing durability even if single yarn of the silver wire included in the mask occurs. There is an urgent need to develop masks.

Meanwhile, the sheath may have an average thickness of 3 to 3200 nm, and preferably, an average thickness of 5 to 3000 nm. If the average thickness of the sheath is less than 3 nm, as the copper, which is the central metal, is easily exposed to the outside, the intrinsic functional properties of silver may be deteriorated, the silver may be detached from the silver wire and inhaled into the user's respiratory tract, and the average thickness If the value exceeds 3200 nm, the flexibility of the silver wire may be reduced.

In addition, the silver wire may include 0.1 to 15% by weight of copper, preferably 0.1 to 10% by weight of copper, and the balance of silver. If the copper content is less than 0.1% by weight, the flexibility of the silver wire may be reduced, and if it exceeds 15% by weight, the antibacterial performance may be relatively reduced.

Meanwhile, the first covering yarn 12a may be twisted in the opposite direction to the second covering yarn 13a. For example, when the first covering yarn 12a is a left edge (Z twist), the second covering yarn 13a may be a coincidence (S twist), and the first covering yarn 12a is a coincidence (S twist). In Gunwoo, the second covering yarn 13a may be a left edge (Z twist). Through this, there is an effect that the first covering yarn 12a and the second covering yarn 13a are more firmly provided while the flexibility of the first fiber 10 is excellent.

If the first covering yarn 12a and the second covering yarn 13a are twisted in the same direction, the first covering yarn 12a and the second covering yarn 13a are not relatively strong, so weaving the fabric After that, if any one of the first covering part 12 or the second covering part 13 is damaged, a problem in which the yarn is unwound in one direction may occur.

The first fiber 10 may have a total fineness of 100 to 400De, preferably 130 to 370De. If the total fineness of the first fiber is less than 100 De, antibacterial performance may be reduced, washing durability and elasticity may be reduced, and if the total fineness exceeds 400 De, flexibility may be reduced.

Meanwhile, the third fabric may be a fabric or knitted fabric manufactured by weaving or knitting.

According to an embodiment of the present invention, the third fabric may be a fabric including warp and weft yarns, the warp may include the first fiber 10 , and the weft yarn may include a second fiber. have. Alternatively, the weft yarn may include the first fiber 10 , and the warp yarn may include the second fiber.

In this case, the second fiber may be used without limitation as long as it is a fiber commonly used in the art, and preferably, any one or more selected from natural fibers and synthetic fibers may be used, and more preferably polyester-based fibers. Can be used.

The first fiber 10 provided in the third fabric may have a batch width of 0.01 to 12 mm in the fabric, preferably 1 to 7 mm, and more preferably a batch width of 3 to 12 mm. It may be 6 mm. If the batch width in the third fabric of the first fiber is less than 0.01 mm, the flexibility of the fabric may be reduced, and if the batch width exceeds 12 mm, the desired level of antibacterial performance may not be expressed.

Meanwhile, the third fabric may be a mesh formed of the first fibers 10 described above. In this case, the number of meshes of the third fabric may be 40 to 450 meshes, preferably 50 to 400 meshes. If the third fabric is less than 40 mesh, antibacterial performance and mechanical properties of the third fabric may be reduced, and if it exceeds 400 mesh, flexibility may be reduced.

Meanwhile, according to another embodiment of the present invention, the first fabrics 100 and 101, the second fabrics 300 and 301 and the functional media 200 and 201 each include a first fiber 10 including a silver wire. can be

In this case, the material and detailed specifications of the first fabric 100 and 101 , the second fabric 300 , 301 , and the functional filter media 200 and 201 , and the first fiber including the silver wire are the above-described third fabric and the third fabric. Since the material and detailed specifications of the first fiber including the silver wire included in the are the same, a description thereof will be omitted.

In addition, the mask 1000 according to the present invention includes ear bands 400 provided on both side ends of the first fabric 100, and the ear band 400 has the same material and shape as the known ear bands. As possible, the present invention is not particularly limited thereto.
