What special place does the pricking method of needling non-woven fabric have | JINHAOCHENG

The basic principle of the structure reinforcement process of needling non-woven fabrics is to carry out continuous piercing for the fiber mesh by means of triangular cross section (or other cross section) edges with barbs.

When barbs cross the mesh, they force plant fibers on the surface and part of the inner layer into the mesh.Because of the friction in the middle of the plant fibers, the net that used to be loose has been reduced.

When a pin is used to release the mesh, the inserted bundle is released from the barb surface and left in the mesh. In this way, many of the bundles become entangled in the mesh so that it cannot respond to the original loose condition.

After many times of needling, a large number of fiber bundles are pierced into the fiber network to produce "three-dimensional structure", which makes the plant fibers intertwined with each other in the fiber network, certain strong and thin thick needling non-woven raw materials.

The surface also sticks to only a small amount of dust.Under the same load standard, the use life of the filter material will be 1-3 times higher than that of other materials.

With high cost performance.As demand expands, costs will be further reduced to acceptable prices.Characteristics and distinguishing characteristics of several types of organic chemical plant fibers.
