There is talk of what would be the best material for a face mask to protect you from the virus. Tests, experiments were performed and, more recently, it was concluded that a material would be the most effective.
The addition of a third layer to the cloth masks is now recommended to prevent the spread of COVID-19. Polypropylene fabric is the material chosen for this third layer, but many people may not know what this material is or where to get it.
Which is the most suitable mask
If you use a mask made at home or by clothing companies, here’s what you need to know about the new recommendations of the Public Health Agency of Canada.
Each study that examined layering found that using extra layers in face masks improves filtration, but some fabrics provide more filtration than others. Thus, the use of polypropylene as a middle layer in cloth masks is specifically recommended.
Polypropylene for the clothing industry has a non-woven structure. Nonwovens have a random arrangement of fibers, such as spaghetti on a plate. This random character allows high particle filtration and at the same time you can easily breathe through it.
Polypropylene can be cleaned according to Health Canada recommendations: a warm detergent wash. Also, do not use the iron: it is plastic and will melt.
Polypropylene is used as the middle layer of many certified medical masks and in the manufacture of N95 respirators, because it filters very well.
Obviously, many designers have made the pandemic an opportunity to create products that meet the needs of protection against coronavirus – and they have done so in the most bizarre ways possible. For the past two months, inventor Yezin Al-Qaysi has traveled by subway in Toronto, Canada, wearing a strangely huge helmet. It completely covers his head and upper body and has a visor that extends to the chest.
