Spines are a process of fiber consolidation and winding by using fine high-pressure water jets. Nonwovens are produced in this way by first combing the fibers into a network structure and then passing the network through a series of high-pressure water curtains, which are used to tangle the fibers and create many fiber-to-fiber interweaving points. This technology can produce nonwovens with high fabric uniformity, high strength-to-weight ratio, lower average aperture and increased absorption properties. Specially customized filter material spina felt three-dimensional filter layer, filtrate flowing through the filter material, particles will be trapped on the inner surface of the filter material and deep because of the deep filtration mechanism, the special filter material production process, has high trapping efficiency for fine particles.
