1. Spunlace: A high-pressure fine water stream is sprayed onto one or more layers of fiber webs to entangle the fibers with each other, so that the fiber web can be reinforced and has a certain strength.

2. Heat-bonded non-woven bag: refers to the addition of fibrous or powdered hot-melt bonding reinforcement material to the fiber web, and the fiber web is further fused and cooled to form a cloth.

3, pulp airlaid non-woven bag: can also be called dust-free paper, dry papermaking non-woven fabric. It uses the air-laid technology to open the wood pulp fiber board into a single fiber state, and then uses a gas flow method to agglomerate the fibers on the mesh curtain, and the fiber web is further reinforced into a cloth.

4. Wet-laid non-woven bag: the fiber raw material placed in the water medium is opened into a single fiber, and at the same time, different fiber raw materials are mixed to form a fiber suspension slurry, and the suspended pulp is transported to a web forming mechanism, and the fiber is in a wet state. Reinforce the cloth into a cloth.

5. Spunbond non-woven bag: After the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a net, and the web is then bonded, thermally bonded, chemically bonded or mechanically. The reinforcement method makes the web into a non-woven fabric.
