Specifically, a study by an Australian team of scientists published last week in Thorax showed that a three-layer medical mask made from nonwoven material also had a significant effect on reducing the droplets splashed while say, cough or sneeze. 3-layer masks are proven to be more effective than double and single-layer masks. The team noted that the effectiveness of the mask also decreased with thinness. The Australian scientists' research is also significantly similar to the findings of the research published last month in the journal Physics of Fluids by researchers at Florida Atlantic University. Researchers hope that with more and more scientific evidence on the effectiveness of the COVID-19 prevention function of medical masks, people will be more conscious of wearing this item.An analysis of the study published on July 26 in the journal BMJ medical journal said that the current wearing of mandatory masks is done in 160 countries to reduce COVID-19 infection. In fact, researchers around the world find that even wearing basic cloth masks can help prevent infection more effectively than not wearing anything. In the context of scarcity of N95 respirators, which are rated as the most preventable, but often preferred for health care workers, there has been research proving that the risk of infection is still significantly reduced with These masks are simple and cheaper than the N95.
The outer layer has waterproof properties, effectively preventing the liquid particles from being splashed when the patient sneezes, coughs, breathes hard ... The outside surface is usually light blue to distinguish easily. The inner layer is always white, very easy to distinguish from the outer layer. The face of the cloth turns inwards, close to the skin of the face, so it must be pure and smooth, without fiber fibers causing discomfort. In addition, it must be waterproof to sweat to create comfort for the user. The middle layer prevents particles from splashing and must filter dust and bacteria. This is the layer that determines the quality of the mask. A "right" layer of filter must allow air to pass easily, creating a sense of ventilation for the user, but must have a structure sufficient to filter out extremely small particles of bacteria and dust. Conventional nonwoven fabric has 3 layers with different uses. The outer layer has waterproof properties, effectively preventing the liquid particles from being splashed when the patient sneezes, coughs, breathes hard ... The outside surface is usually light blue to distinguish easily.
