(1) Natural fibers: cotton, wool, hemp and silk;

(2) Conventional fibers: viscose fiber, polyester fiber, acetate fiber, polypropylene fiber and polyamide fiber;

(3) Differential fiber: superfine fiber, profiled fiber, low melting point fiber, high crimp fiber and antistatic fiber;

(4) High-functional fibers: aromatic polyamide fibers, carbon fibers and metal fibers.

2. Spunlaced nonwovens are spunlaced nonwovens by spraying high-pressure micro-water on one or more layers of fiber webs to interweave the fibers, so that the fiber webs are strengthened and have certain strength. Its fiber raw materials are widely available, such as polyester, nylon, polypropylene fiber, viscose fiber, chitin fiber, superfine fiber, Tencel, silk, bamboo fiber, wood pulp fiber, seaweed fiber and so on.
