The fibers used in the production of non-woven fabrics are mainly polypropylene (PP) and polyester (PET). In addition, there are nylon (PA), viscose, acrylic, ethylene (HDPE), and vinyl (PVC). According to application requirements, non-woven fabrics are divided into two categories: disposable application type and durable type.

1. Spunlace non-woven fabric: The spunlace process is to spray high-pressure fine water flow onto one or more layers of fiber webs, so that the fibers are entangled with each other, so that the fiber webs can be reinforced and have a certain strength.

2. Heat-bonded non-woven fabrics: Heat-bonded non-woven fabrics refer to adding fibrous or powdery hot-melt bonding reinforcement materials to the fiber web, and the fiber web is then heated, melted, cooled, and reinforced into cloth.

3. Pulp air-laid non-woven fabrics: Air-laid non-woven fabrics can also be called dust-free paper and dry-laid non-woven fabrics. It uses the air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses the air-laid method to condense the fibers on the web-forming curtain, and the fiber web is reinforced into a cloth.
