Why Our Cloth Face Mask Uses Knit Fabric?
Knit fabrics are made by connecting loops of yarn, rather than straight laces. In fact, you can see these loops if you look closely enough at your mask. You’ll notice that the surface of the fabric looks almost 3-dimensional, with “peaks” and “valleys” between the rows of yarns. These loops can be easily stretched in different directions, making knit fabrics much more elastic than woven fabrics. These comfortable fabrics are commonly used in casual and active clothing of all kinds, including tees and socks.
The added elasticity of knit fabrics makes them ideal for a well-fitting face mask. It allows the mask to easily stretch when you put it on, forming a tighter but more comfortable seal against your skin. A closer fit eliminates gaps for air to flow between the mask and your skin.
Knit fabrics, especially cotton like we use in our Cloth Face Mask, are excellent for moisture wicking. The loops of the fabric form small openings between the yarns, serving as tiny pockets that hold small amounts of air or moisture. This is ideal for a face mask because it helps absorb more moisture and droplets from coughs, sneezes, and normal day-to-day activities.
Breathability is an extremely important factor in a face mask's performance. A mask that allows more air flow not only allows you to breathe more easily, it’s also crucial for any filtration effects. Knit fabrics are great for breathability because of their looped construction. Rather than forming a flat, compact wall like a woven fabric, the interlocked loops of our knit cotton create a complex and 3-dimensional pattern of yarns and pockets. This lets air flow through the mask while still helping provide coverage and absorb moisture.
