With special singed treatment, the felt can avoid the pollution of falling fiber at the same time, it also avoid the excessive clogging and shortening the lifetime caused by traditional calendering. The needle punching method leads the three-dimensional filtration, adopts the indepth filtration. It has high ability of catching to the solid or the gluey particle. The material is even in thickness, the steady size of hole and
strengthening the tensility. The precision is among 1-200 microns, the material is mainly polypropylene or polyester.
