How to distinguish the melt blown cloth in the middle of the mask

To identify whether the middle of the mask is a flannel cloth, we can prepare a piece of white paper, cut it into small pieces with scissors, and then fold the small paper pieces in the middle of the mask for adsorption. If the paper pieces are sucked onto the mask, it means that there is a melt blown cloth in the mask. Almost all normal medical masks have melt blown cloth and electrostatic electret, otherwise the filtering effect will not meet the standard. How to distinguish melt blown cloth in order to prevent influenza or virus, many people will buy medical masks for protection. The common medical masks on the market are mainly composed of three layers of non-woven fabrics. The inner layer is ordinary non-woven fabrics, the outer layer is waterproof non-woven fabrics, and the middle is also the most important layer. It uses treated polypropylene spray blown non-woven fabrics, Mainly used to block germs.

Generally, in order to effectively block bacteria, in addition to melt blowing, the filter element material also needs to go through electrostatic electret, so we can use the method of testing static electricity to judge whether there is a flannelette. Prepare a piece of white paper, cut it into small pieces with scissors, and then adsorb the small piece of paper with a medical mask. You can see that the piece of paper is sucked onto the mask.

Melt blown cloth is almost used in regular medical surgical masks and N95 masks, and electrostatic electrets will be made, otherwise the filtering effect will not meet the standard and the effect of blocking bacteria will be lost. When purchasing masks, we must carefully select and buy masks with trademarks, so as not to buy fake goods and pose a threat to our own health.
