What should needle needle non - woven cloth barb pass fiber net to notice?Following jin haocheng needle punch nonwoven fabric manufacturers to understand:
When needle punched non woven barbs through the fiber mesh, the surface of the fiber mesh and the local inner layer of fiber are forced into the fiber mesh inside.Because of friction between the fibers, the formerly fluffy mesh is compressed.
When the needle is pushed out of the mesh, the inserted fiber bundle is left in the mesh off the barb surface, so that many of the fiber bundles become entangled in the mesh, preventing it from regaining its original fluffy state.
After many times of needling, a considerable number of fiber bundles are inserted into the fiber net to form a "three-dimensional structure", which makes the fibers in the fiber net become entangled with each other, thus forming a certain strength and thickness of needling non-woven materials.
