3-Layer Mask is a type of mask produced using a three-layer interlining material. It was therefore named after the 3-Layer Mask. In the parts of these masks that correspond to the nose, there is a wire that allows it to fit properly into the face and, most importantly, does not enter air from the outside and germs. This Wire is not hard or painful. It is available in interlining in a form that can take a bent shape.
The 3-Layer Mask has been prepared in the average face size, which can be suitable for each person, and generally fits everyone. Fabric weights vary decidedly between 68 gr – 90 gr. Also called 3-layer surgical masks can be produced in order to have certain requirements. These medical products, which must be manufactured in accordance with certain standards, are required to obtain certain certificates indicating that the manufacturing enterprises meet or meet all of these requirements. The certificates required for manufacturing medical textile product groups are ISO 13485 and QCS International Certificates. Another standardization of masks is that they must provide 98% bacterial filtration.
How Are Tested
It is tested by four different methods. 3-layer mask when viewed with an eye from the outside, it should appear and be noticed that there are 3 layers. It should not be woven on the outside. There should be a translucent layer on the outside. The innermost part of the 3-layer mask should be both a soft and nonwoven layer.
The remaining middle section should be a section made of polypropylene material. The second test method is whether it catches fire. Materials used in the production of 3-layer masks should not catch fire. For this reason, instead of burning like paper when exposed to fire, they should melt on the contrary. If it burns when you expose your mask to fire, it is not manufactured according to production standards. But if it melts, it means it meets one of the production standards that can be tested.
3-layer surgical masks should not be waterproof. His designs are made in this way, and his standards are in this direction. If you pour some water or any liquid from the outside of the mask, it should not leak it. This test is also a test that you can easily apply. If there is a leak, it is not produced in accordance with the standards, but if there is no leak, your mask will also pass this test. Finally, there is again an easy test.
The most important feature of 3-layer masks should prevent airborne particles, that is, living things such as viruses, bacteria, from being taken into the body during respiration. So he shouldn’t be breathing. In order to understand this, it is to try to extinguish any burning match, candle or lighter by blowing. If you can’t blow out the burning fire, your mask is blocking the entry of airborne particles into your body through the respiratory tract, but if you can, you need to change your mask immediately.

The latter fabric etc. these are types of masks made with materials. 3-Layer Mask also belongs to this category. These masks protect people from various diseases and types of germs. The third group of masks are masks with visors. These masks are made of protective quality. It protects the face and eyes from blows or any other dangers.
