Non-woven fabrics do not have warp and weft threads, so it is very convenient to cut and sew, and it is lightweight and easy to set, which is loved by hand lovers.
Because it is a kind of fabric that does not require spinning and weaving, it is just oriented or randomly arranged short fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods.
It is not interwoven and braided by individual yarns, but the fibers are directly bonded together physically, so when you get the sticky name in your clothes, you will find It's impossible to pull out any thread. Non-woven fabric breaks through the traditional textile principle, and has the characteristics of short process flow, fast production rate, high output, low cost, wide use, and many raw material sources.
There are two types of non-woven masks. One is made of pure cotton absorbent gauze or knitted fabric with various non-woven fabrics in between; the other is directly sewn from non-woven fabrics. It has good filtering effect and slightly poor air permeability. The latest varieties are non-woven materials on the front and back, and filter paper in the middle, so that the filtering effect of non-woven masks can be further improved
