摘要：
A bulky nonwoven fabric comprises fine fibers forming thin intertwined layers extending between one surface of the fabric and the other surface, that is, the layered fibers run in the direction of thickness of the fabric. The nonwoven fabric of thermoplastic resin is prepared by a melt-blowing process utilizing a drum collector and cooperating nip-roll. If desired the fiber and gas stream may be contacted with fine liquid drops.
