Fiber (fiber) is to have an antimicrobial function by impregnating (deposition) of nano silver particles having a strong antimicrobial force in the yaw (凹; 22, 32) that is a natural groove generated in the manufacturing process.

Description

Antibacterial face mask

According to various literatures, sterilization and antibacterial function by nano silver are certainly effective, but the mechanism of how silver (Ag), a natural antimicrobial agent, has antiseptic and antibacterial function against bacteria is not known yet. However, scientists estimate that with numerous experiments and research cases:

First, antibacterial and bactericidal action by silver (Ag) positive ion is strongly associated with -SH, -COOH, and -OH groups of bacteria, presuming to destroy bacterial cell membranes or disrupt cellular functions. Second, the antimicrobial and bactericidal function of oxygen (O2) is converted to active oxygen (O2 +, O2-, O) by the catalytic action of colloidal nanosilver. Third, antimicrobial and bactericidal function of nano silver as metal. In case of nano silver, the particle size of nano silver is less than about 2nm ~ 10nm, and microorganism of 100nm ~ 200nm size is ingested. It is assumed to be removed.

The present invention relates to an antibacterial mask that prevents diseases such as a cold caused by virus transmission and infection in the air by using nano silver having strong antimicrobial as described above. The present invention relates to an antibacterial mask that removes viruses or prevents cold viruses from infecting the respiratory tract.

In order to manufacture the antimicrobial mask as described above easily and inexpensively, the masks already woven with cotton yarn and cut and sewn with a general mask are adjusted to a concentration of 100 ppm to 300 ppm of nano silver of particles of about 2 nm to 10 nm or less in a washing machine drum. Put the aqueous solution together to prepare an antibacterial mask by washing, dehydrating the hot-air drying, ironing, packaging process.

Its function is maintained even after long-term use or washing. It is 2 to 10 nm due to the vortex action of the nano-silver aqueous solution generated in the washing machine drum in the recess, which is a natural minute groove on the surface of the mask yarn. The nano silver particles are deposited so that washing does not lose their function.

Conventional antimicrobial masks are coated with organic antimicrobial agents or natural antimicrobial agents extracted from plants, but in the case of organic antimicrobial agents and natural antimicrobial agents, polymer resin adhesives are diluted with resin binders to attach and coat antimicrobial agents on dish cloths. Silver laundry, when boiled, there is a disadvantage that the attached or contained antibacterial components are separated and its function is gradually lost.

The present invention is intended to prevent the infection of large particles in the general face masks (20, 61b) that have already been cut and sewn, as well as to prevent infection of airborne bacteria or viruses through the mouth when breathing. 100ppm to 300ppm colloidal nanosilver for fast and strong antimicrobial activity, and many nanosilver particles of 2nm to 10nm particle size are made of fine grooves on the surface of fibrous fiber that make up the outer, inner fabric and yarn of ordinary face mask.凹: 22, 32) relates to a female antibacterial face mask (50, 60) designed to have an antibacterial function by impregnation (deposition).

The composition of the present invention is a large number of 2nm to 10nm nanosilver particles in 100ppm to 300ppm colloidal nanosilver aqueous solution to have antimicrobial and bactericidal properties on the fine recesses (22:32) of the surface of the fiber fibers constituting the general face mask 20. (21) by impregnating (deposition: 23, 33) to have an antibacterial function and sterilization function to prevent the penetration of relatively large dust, bacteria, viruses into the human body as an antibacterial facial mask fiber cotton fiber (fiber: 30) Photograph of the surface of the yaw (22: 32) of the outer surface Fine nano silver on the part of the fiber surface (31) without the important and the yaw (22: 32) of the fiber surface of the SEM photograph (30) The fact that the particles are impregnated (deposition: 23, 33) shows that the fine yaw (22: 33) portion of the yarn fiber constituting the general face mask of Fig. 2 and the nanosilver particles are actually impregnated. SEM picture (Fig. 2) and a general face mask (20, 61b) and colloidal nanosilver aqueous solution (61a) were put in the washing machine drum, and the washing function was selected. After washing for 45 minutes, the aqueous solution in which the nanosilver particles were dispersed in the drum was rotated by the left and right repetitive rotation function of the washing rod in the washing machine drum. Vortex occurs and nanosilver particles dispersed in the aqueous solution by the force of the vortex action 62 are impregnated (deposition: 23, 63) on both sides of the general face mask (antideposition: 23, 63) antibacterial face mask (50 60) are made. The antibacterial face masks (22: 33) made of nano silver are impregnated with particles (deposition: 23.63). SEM photograph of FIG. 2 photographing the fine yaw portion of the constituent yarn fiber surface and the nano silver particles are actually impregnated, and the surface portion of the pure lining to which the nano silver particles are impregnated. 51), face mask contact (52), strap After impregnating the nanosilver particles in all the recesses such as the cut 53 and the nanosilver particles (55) after the TEM photographing 55 to check whether the nanosilver particles (23, 33, 54, 54a) are dispersed. It was confirmed that 54a) was well dispersed in each yaw portion of the mask.

The manufacturing method and product of the colloidal nanosilver 61a used in the present invention have already been applied for a patent (International Patent; Colloid solution of metal nanopaticles, metal-polymer nanocomposites and methods for preparation) (PCT / KRO2 / OO800, Korean Patent No. 2002- 20594) Colloidal Nanosilver products, or similar products, have a strong charge on each particle by adding a high voltage of 10,000V to 15,000V to make silver (Ag) particles as small as possible. The colloidal nanosilver produced and produced in this way has a particle size of 2 nm to 8 nm, and there are about 26.4 billion particles / ml (cc) particles in the colloidal nanosilver solution. Nanosilver particles using low voltage in silver manufacturing method have very small number of particles dispersed in 5nm ~ 400nm, about 1.4 million / ml (cc). Represented by the brown or pale yellow side is that there are limits to apply in various fields.
