Meltblown material cloth is carried out according to the function of a mechanical equipment, that is, the acupuncture needle puncture function of the needling machine, the swelling of the fiber network structure to consolidate the strong.
Using triangular cross - section (or other cross - section) edge, the barbed needle with barb, continue to puncture the fiber network.When the barb goes over the fiber net, it will force the chemical fiber inside the fiber net into the fiber net.Because of the chemical fiber in the middle of the effect of friction, grain prick needle, ring type prick needle and tube type prick needle.
The basic concept is: the non-woven processing technology is divided into pre-prick, main prick, shrink the original bulk fiber network.When the needle is removed from the mesh, the inserted fiber bundle is left in the mesh. In this way, many fiber bundles become entangled in the mesh, making it no longer loose.
After several times of needling, a large number of fiber bundles are punctured into the fiber net, so that the chemical fibers in the fiber net become entangled with each other, and then become a certain strength and thickness, needling nonwoven raw materials.
