What kinds of nonwovens are there?

According to the production process, it can be divided into the following five types:


1. Spunlace non-woven fabric: spunlace technology is to spray high-pressure micro water to one or more layers of fiber nets, so that the fibers are intertwined, so that the fiber nets can be strengthened and have a certain strength.


2. Thermal bonded non-woven fabric: thermal bonded non-woven fabric refers to the addition of fiber like or powder like hot-melt bonding reinforcement materials to the fiber mesh, which is then heated, melted and cooled to form a cloth.


3. Pulp air laid nonwovens: air laid nonwovens can also be called dust-free paper and dry paper-making nonwovens. It uses the air flow to form a net to loosen the wood pulp fiberboard into a single fiber state, and then uses the air flow method to make the fiber agglutinate on the net forming curtain, and then the fiber net is reinforced into a cloth.


4. Wet non-woven fabric: wet non-woven fabric is to loosen the fiber raw materials placed in the water medium into a single fiber, at the same time, mix different fiber raw materials to make fiber suspension slurry, which is transported to the network forming mechanism, and then the fiber is formed into a network in the wet state and then reinforced into a cloth.


5. Anti sticking non-woven fabric: after the polymer has been extruded and stretched to form a continuous filament, the filament is laid into a network, and then the network is made into a non-woven fabric through self adhesion, thermal adhesion, chemical adhesion or mechanical reinforcement.
