The hot-rolled bonded nonwovens process of the bonding machine uses one or two pairs of steel rollers or steel rollers covered with other materials to heat and pressurize the fiber web, which causes part of the fiber in the fiber web to melt and bond, the Mesh is reinforced to become a hot-rolled nonwovens. The hot-rolling bonding of the bonding machine is a very complicated process. During the process, a series of changes have taken place, including the pressing and heating of the web, the deformation of the web, and the melting of some fibers in the web, melt the flow of polymer and cooling forming, and so on.
