    The fiber can be broken cloth, man-made fiber or synthetic fiber (glue, resin, etc.). The fiber raw material of non-woven fabric often contains polypropylene (Polypropylene), referred to as PP, which is continuously melted by high temperature, spinning, laying and hot pressing. It is produced by one-step method, or polyethylene, or PE for short.

    Non-woven fabrics are not woven by warp and weft like woven fabrics. The production of non-woven fabrics varies with different methods. For example, the needle rolling method uses thousands of needles to continuously hook cotton up and down to make the cotton Tangled with each other, each tangled will make the cotton body more and more solid.
