Description

Sterilizing mask

This creation is a sterilizing mask, especially a sterilizing mask that uses silver-containing fibers to achieve sterilization, bacteriostatic and antibacterial effects.

Air is one of the basic elements of human life, and life must have air to survive. However, with the development of human industry and technology, modern air pollution is becoming more and more serious. Although it cannot be seen by the naked eye, the concentration of PM2.5 and bacteria in the air gradually rises.

According to the survey, in 2016, lung cancer has become the cancer with the highest morbidity and mortality, surpassing the public's understanding of intestinal cancer or liver cancer. And more and more patients do not have bad habits such as smoking or drinking. Many studies have pointed out that air pollution increases the incidence of lung cancer.

In the face of gradually serious air pollution, wearing a mask is a very direct means of prevention, but the masks are numerous and the functions are not the same. Although most masks have the ability to isolate PM2.5 to a certain extent, most of them are only isolated and do not have germicidal functions. Also, the masks are mostly woven products. It is easy to let bacteria grow on the mask for a long time, which is harmful to the wearer's health.

In summary, how to solve the above problems and overcome the problem of residual bacteria in the mask is a matter of general knowledge in the field.

The present invention provides a sterilizing mask having a multi-layer filter layer to block a bad substance, and sterilizing with a fiber containing silver ions, so that the mask has a bactericidal effect.

The present invention provides a sterilizing mask comprising a germicidal layer and a first filter layer, the germicidal layer being a silver-containing fiber. The first filter layer is a nanofiber cloth.

Figure 1 depicts the sterilizing mask of the present invention.

Figure 2 depicts the layered structure of the sterilizing mask.

Please refer to FIG. 1 , which illustrates the sterilizing mask of the present invention. The present invention proposes a sterilizing mask 100, which is designed to pass through a multi-layer design and incorporate a silver-containing cloth therein, so that the sterilizing mask 100 can also eliminate bacteria on the mask while the bad substance is isolated, so that the bacteria can not easily pass through the mask or remain in the mouth. On the mask.

Please refer to FIG. 2, which illustrates the layered structure of the sterilizing mask. The sterilizing mask 100 includes a germicidal layer 110, a first filter layer 120, a second filter layer 130 and an outer skin 140. The sterilizing layer 110 is the main structure of the sterilizing mask 100, and the sterilizing layer 110 is the inner material of the sterilizing mask 100, which is relatively close to wearing. The skin of the person. The germicidal layer 110 is a silver-containing fiber, preferably a nano-sized silver ion elastic fiber cloth. In the present embodiment, a plurality of silver ions are included in the germicidal layer 110.

Since silver ions are a positive charge, when silver ions come into contact with bacteria, they combine with the negative charge of the proteins in the bacteria, so the silver ions penetrate the bacterial cell membrane and enter the bacteria. The silver ions entering the bacteria cause the protein in the bacteria to change, allowing the bacteria to lose their metabolic, respiratory and reproductive functions until the bacteria die. After the death of the bacteria, the silver ions can still affect other bacteria, thereby achieving the function of sterilization. Silver ions are therefore a fairly effective bactericide.

The sterilizing layer 110 of the present embodiment is a nano-sized silver ion elastic fiber cloth. Tested in AATCC 100-2012 for S. aureus and K. pneumoniae. The test results showed that the sterilization rate of the nano-scale silver ion elastic fiber cloth to Staphylococcus aureus was 99.6%; the sterilization rate against the K. pneumoniae test was 98.9%. In addition, the nano-scale silver ion elastic fiber cloth has passed the CNS14774 T5017-2011 9.2 and CNS14775 T4037-2003 tests for the sterilization test of Staphylococcus aureus. After five tests, the test results show that the nano-scale silver ion elasticity The sterilization rate of the fiber cloth to Staphylococcus aureus was 99.8%, 99.9%, 99.9%, 99.8%, and 99.8%, respectively. It can be known that the sterilization rate of the nano-scale silver ion elastic fiber cloth is close to 100%, and has a good bactericidal effect.

The first filter layer 120 is disposed before the germicidal layer 110 to filter harmful substances and block harmful substances from passing through the sterilization mask 100. In this embodiment, the first filter layer 120 is a nanofiber cloth. Therefore, the first filter layer 120 includes a non-woven fabric, and the first filter layer 120 is based on a non-woven fabric. The first filter layer 120 further includes a nanofiber layer, and the nanofiber layer includes at least one hydrophilic polymer or a hydrophobic layer. Polymer. In one embodiment, the nanofiber layer can also include both a hydrophilic polymer and a hydrophobic polymer.

In the nanofiber layer, the hydrophilic polymer and the hydrophobic polymer are overlapped and interlaced with each other, and the nanofiber layer area is comprehensively covered, and is disposed on the non-woven fabric to complete the first filter layer 120. Hydrophilic The overlap and interlacing of the polymer with the hydrophobic polymer allows the first filter layer 120 to block most of the undesirable materials, such as bacteria, dust mites, PM2.5 particles, and the like.

The first filter layer 120 of the present invention is tested by FTTS-FP-157, with a rated gas flow rate of 85 LPM; a test area of 100 cm ² ; a temperature of 26 ± 2 ° C; a humidity of 43 ± 5%; and an aerosol type of potassium chloride (KCl). Test it down and test it three times. The test results show that the filtration efficiency of the first filter layer 120 for the particle diameter of 2.5 μm (ie, PM2.5) is 97.91%, 96.88%, and 96.67%, respectively, and the average filtration rate is 97.15%. It can be confirmed that the first filter layer 120 can block most of the PM2.5 particles and bacteria. The bacteria remaining on the first filter layer 120 by filtration are destroyed by the adjacent germicidal layer 110.

The second filter layer 130 is a filter cloth of the N95 grade. N95 grade refers to the filter fabric conforming to the NIOSH (National Occupational Health and Safety Research Institute) N95 specification, that is, under the test standard established by NIOSH, it can achieve 95% filtration efficiency for non-oily particles, which can be called N95 grade. Filter the fabric. Therefore, the second filter layer 130 can initially block part of the undesirable substances, particularly bacteria and viruses. The bacteria and viruses remaining on the second filter layer 130 by filtration are destroyed by the adjacent germicidal layer 110.

The outer skin 140 is disposed at the outermost layer of the sterilizing mask 100, covers the entire sterilizing mask 100, and is in contact with air. In the present embodiment, the outer surface layer 140 is an elastic fiber cloth, which enables the sterilization mask 100 to have elasticity. When the user wears the sterilization mask 100, the skin can be more closely adhered to the skin, thereby ensuring the effectiveness of the sterilization mask 100 to block and eliminate undesirable substances.

Different from the traditional mask, the sterilization mask 100 has the first filter layer 120 and the second filter layer 130 capable of filtering most harmful substances, and the fiber containing silver ions is used as the germicidal layer 110. The bacteria that want to pass through the sterilizing mask 100 and the bacteria that stay on the first filter layer 120 and the second filter layer 130 are effectively eliminated, and the bactericidal, antibacterial and antibacterial effects are achieved. Sterilizing mask 100 blocks UV rays, dust mites, PM2.5, sandstorms, car exhaust, allergens, pollen, various bacteria, molds and Bad substances such as viruses. Therefore, the sterilizing mask 100 of the present invention is particularly suitable for use in hospitals for use by doctors in performing medical business, and is free from bacterial infestation when the doctor is exposed to an environment with a large number of bacteria.
