Because it is a kind of fabric formed without spinning and weaving, it is only formed by orienting or randomly arranging textile short fibers or filaments to form a network structure, and then strengthening it by mechanical, thermal bonding or chemical methods.
It is not woven by interweaving a yarn, but directly bonds the fibers together by physical methods, so when you get the sticky scales in your clothes, you will find that you can't even draw a thread. Nonwovens break through the traditional textile principle, and have the characteristics of short technological process, high production speed, high output, low cost, wide application and many sources of raw materials [1].
