Water jet nonwoven: The water jet process is to spray high-pressure fine water onto one or more layers of fiber webs, causing the fibers to entangle with each other, thereby reinforcing the fiber webs and giving them a certain strength.


Thermal bonded non-woven fabric: Thermal bonded non-woven fabric refers to adding fibrous or powdery hot melt adhesive reinforcement materials to the fiber web, and then heating, melting, and cooling the fiber web to reinforce it into a fabric.


Airflow networking: Airflow networking non-woven fabric can also be called dust-free paper or dry papermaking non-woven fabric. It uses air flow web technology to loosen wood pulp fiberboard into a single fiber state, and then uses air flow method to aggregate the fibers on the web curtain, and the fiber web is reinforced into fabric.


Wet non-woven fabric: Wet non-woven fabric is made by loosening fiber raw materials placed in an aqueous medium into single fibers, and mixing different fiber raw materials to produce fiber suspension slurry. The suspension slurry is transported to the web forming mechanism, and the fibers are formed into a web in a wet state and then reinforced into fabric.


Spunbond nonwoven fabric: Spunbond nonwoven fabric is formed by extruding and stretching polymers into continuous filaments, which are then laid into a web. The web is then subjected to self bonding, thermal bonding, chemical bonding, or mechanical reinforcement methods to turn the web into nonwoven fabric.


Melt blown non-woven fabric: The process of melt blown non-woven fabric includes polymer feeding, melt extrusion, fiber formation, fiber cooling, web formation, and reinforcement into fabric.


Needle punched non-woven fabric: a type of dry non-woven fabric that uses the puncture effect of needles to reinforce fluffy fiber webs into fabric.


Stitching non-woven fabric: Stitching non-woven fabric is a type of dry non-woven fabric. Stitching method uses a warp knitted coil structure to reinforce fiber webs, yarn layers, non-woven materials (such as plastic sheets, plastic thin metal foils, etc.) or their combinations to make non-woven fabric.
