Net forming structure and process of melt-blown cloth

The invention discloses a net forming structure and process of melt-blown cloth. The net forming structure comprises a spinneret plate which is arranged above a net forming curtain and has a hot air drafting function, wherein electrostatic electrets are arranged on two sides of a spinneret hole in the lower portion of the spinneret plate, a magnet is arranged between the spinneret plate and the net forming curtain, and the direction of a lorentz force generated by a magnetic field of the magnet to a fiber is consistent with the movement direction of the spun fiber. According to the net formingstructure, the space magnetic field is constructed in a spinning area, when the fiber is sprayed out of the spinneret hole, hot air and the magnetic field are used for conducting drafting treatment on the fiber at the same time, the drafting effect can be greatly improved, and therefore the purpose of improving the product filtering effect is achieved. 本发明公开了一种熔喷布的成网结构及工艺，包括设置在成网帘上方的带有热风牵伸功能的喷丝板，喷丝板的下方喷丝孔两侧设置有静电驻极机，喷丝板与成
