1.Hydroentangled nonwoven
The hydroentanglement process is to spray a high-pressure micro-fine water jet onto one or more layers of fiber webs,so that the fibers are entangled with each other and the webs are reinforced and have a certain strength.
2,thermally bonded nonwoven fabric
Thermally bonded nonwoven refers to the addition of fibrous or powdered hot melt bonding reinforcing material to the fiber web,which is then heated and melted and cooled to reinforce the cloth.
3,pulp air flow nonwoven fabric
Air flow into the network of nonwoven fabrics can also be called dust-free paper,dry paper nonwoven.It is the use of airflow into the network technology to open the wood pulp fiber board into a single fiber state,and then use the airflow method to make fiber agglomeration in the formation of network curtain,fiber network and then reinforced into cloth.
4,wet nonwoven fabric
Wet nonwoven fabric is placed in the aqueous medium to open the fiber raw materials into single fiber,while making different fiber raw materials mixed to make fiber suspension pulp,suspension pulp transported to the web-forming mechanism,fiber in the wet state into the web and then reinforced into cloth.
5,Spunbond Nonwoven Fabric
Spunbond nonwoven fabric is formed after the polymer has been extruded and stretched to form a continuous filament,the filament is laid into a network,and the fiber network then undergoes its own bonding,thermal bonding,chemical bonding or mechanical reinforcement methods to make the fiber network into a nonwoven fabric.
6,meltblown nonwoven
The process of meltblown nonwoven fabric:polymer feeding---melt extrusion---fiber formation---fiber cooling---web formation---reinforcement into cloth.
7,needle punching nonwoven
Needle punching nonwoven is a kind of dry nonwoven fabric.Needle punching nonwoven fabric uses the piercing effect of needles to reinforce the fluffy fiber network into cloth.
8,sewn nonwoven fabric
Sewn nonwoven fabric is a kind of dry nonwoven fabric.Sewn knitting method uses the warp knitting coil structure to reinforce the fiber web,yarn layer,non-textile materials(such as plastic sheet,plastic thin metal foil,etc.)or their combination to make nonwoven fabric.What kinds of nonwovens are there?
