Non woven mask is a kind of mask that is made of pure cotton absorbent gauze or surface with various non-woven fabrics in the middle layer or sewn from non-woven fabrics directly. Non woven mask requires the non woven machine such as non woven fabric slitting machine or spunmelt non woven machine to be produced to reach the high filtering effect and hygiene requirements. Due to the COVID-19 pandemic going worse since 2019, the requirements of non woven mask correspondingly become stricter than before.
Dust Blocking Ability
1. The standard to judge the ability of blocking dust outside the nose of a non woven mask is the ability to block fine dust, especially respiratory dust below 5 microns. Because these dust can be inhaled into humans lungs to have an impact on human health directly. Generally, the dust blocking principle of common masks is filtering air mechanically, that means to block some large particles of dust in the mask surface and filtering the air through its layers when the dust collides with the gauze. However, it is not work if some fine dust, especially the dust smaller than 5 microns because they are smaller enough to pass through mask layers and enter the human respiratory system. Some dust masks overseas are made by some filter material that is composed of fibers charged with permanent static electricity so that the dusts that smaller than 5 microns can be attracted by electrostatic attraction and adsorbed on the filter material to capture fine particles during the process of passing through the filter material.
2. Air can flows first to where there is less resistance like the water flow. So the possibility of inhaling dust and air into lungs will be higher if the shape of the non woven mask is not exactly suitable for the users’ face. Even if you choose a non woven mask with the best filter material, nor can your health be guaranteed at that time. The best solution is to choose the right size non woven mask and wear the mask according to the correct steps.
3. The strap-type non woven mask is more flexible than others because user can adjust the wearing tightness according personal habit. The newest non woven mask can achieve a high filtering & sterilization effect with using non woven fabric material as surface and add a filter layer as middle filter which generally be made by melt-blown fabric, has strong air permeability.
Who and When Is Not Suitable For Using It
1. People who has heart or respiratory difficulties (such as asthma, emphysema), dizziness after wearing, breathing difficulties and sensitive skin, pregnant women are all not suitable for using non woven masks.
2. There are always lots of dust, bacteria and other pollutants in air attached on the outer layer of the non woven mask while the exhaled bacteria and saliva attached on the inner layer of non woven mask so that two sides cannot be used alternately, otherwise the bacteria and dust that attached on the outer layer will be inhaled into the human body and becomes a source of infection. It should be folded and placed in a clean pocket with the inner side be folded inward when it is not worn. Do not stuff it into your pocket or hang it around your neck.
Components Of Non Woven Masks
Non woven masks are the most widely used in everyone’s daily life. The components of a non woven mask can be divided into two parts: the main body of the mask, which we can be understand as the frame of a mask simply; the filter material part, including filter cotton for blocking dust and anti-virus. chemical filter cartridges, etc.
