Spunlaced non-woven fabric

The spunlace process involves spraying high-pressure micro water onto one or more layers of fiber mesh, causing the fibers to intertwine and strengthen the mesh to a certain degree of strength.

Heat sealing non-woven

Hot bonded non-woven fabric refers to the addition of fibrous or powdered hot melt bonding reinforcement materials to the fiber mesh, which is then heated, melted, and cooled to form a fabric.

Airflow forming network

Airflow net forming non-woven fabric can also be called dust-free paper or dry paper making non-woven fabric. It uses airflow mesh forming technology to loosen the wood pulp fiberboard into a single fiber state, and then uses airflow method to aggregate the fibers onto the mesh curtain, and the fiber mesh is reinforced into a cloth.

Wet non-woven

Wet non-woven fabric is a process where fiber raw materials placed in a water medium are loosened into single fibers, and different fiber raw materials are mixed to form a fiber suspension slurry. The suspension slurry is transported to a mesh forming mechanism, and the fibers are formed into a mesh in the wet state and then reinforced into a fabric.

Spunbonded non-woven

Spunbonded non-woven fabric is a continuous filament formed by extrusion and stretching of a polymer, which is laid into a web. The web is then self bonded, thermally bonded, chemically bonded, or mechanically reinforced to form a non-woven fabric.

Melt blown non-woven

The process of melt blown non-woven fabric: polymer feeding - melt extrusion - fiber formation - fiber cooling - mesh formation - reinforcement into fabric.

Needled non-woven

Needled non-woven fabric is a type of dry process non-woven fabric that utilizes the puncture effect of a needle to reinforce a fluffy fiber mesh into a fabric.

Sewn non-woven

Stitching non-woven fabric is a type of dry process non-woven fabric, which uses warp knitted coil structure to reinforce fiber mesh, yarn layer, non-woven materials (such as plastic sheets, plastic thin metal foil, etc.) or their combination to make non-woven fabric.
