In daily life, the mask we often is made of non-woven fabric? What is the non-woven fabric?

Non-woven fabrics can be used to make masks, but not all masks are made of non-woven fabrics. Non-woven fabric is also called nonwoven, ie, no woven or textile fabric. It is not intended to be interleaved by the yarn in a conventional sense, but the fiber is bonded directly into a fabric formed by physical methods.

Under the same processing conditions, the non-woven soft product unevenness is usually similar to the cause of uneven thickness. The main reasons may be as follows:

(1) The low melting point fiber and conventional fiber blended cotton is uneven, and the low melting point content is relatively hard, and the low melting point content is more soft.

(2) The incomplete melt of low melting point fibers can cause the nonwoven fabric to be soft

(3) The high shrinkage of fibers may also cause weakness of nonwoven products and uneven stiffness.
