What is special about the fabric of needled non-woven fabric | JINHAOCHENG

Needling non-woven fabric is performed according to the function of a mechanical device, that is, the needle puncture function of the needling machine, which strengthens and holds together the expanded fiber mesh structure to obtain strength.

Needling non-woven fabric using triangular cross section (or other cross section) edges, will be barbed needles, continuous puncture of the fiber net.Barbs across the fiber mesh, the fiber mesh inside the surface layer of chemical fiber, forced into the fiber mesh inside.Because of the friction effect in the middle of the chemical fiber, the line of acupuncture needles, ring acupuncture needles and tube acupuncture needles and so on.

The basic concept of non-woven fabric manufacturing by prick method is as follows: preprick, main prick, shrink the original expanded fiber net.

When the needle is removed from the mesh, the fiber bundles it inserts are left in the mesh, so that many of them become entangled in the mesh, preventing it from swelling.

After several pricks, a large number of fiber bundles are pricked into the fiber net, which makes the chemical fibers in the fiber net become entangled with each other, thus forming the non-woven raw materials with certain strength and thickness.

Above information hopes to have certain help to you, we are a non-woven fabric manufacturer, welcome to consult to understand!
