摘要：
A process for producing a thermoplastic nonwoven fabric having a uniform thickness and optionally napped fibers according to a melt blowing method, which comprises blowing a fiber stream consisting of melt blown fibers and a gas at a high speed onto a plate within a valley-like fiber-collecting zone formed by two plates having a large number of pores, to form a uniform nonwoven fabric without scattering fibers.
