PURPOSE: To obtain a nonwoven fabric especially capable of forming a wide width with a spinning machine of a small number of spinnerets and suitable for a filter base cloth, or the like, by piling fibers conveyed by a high speed fluid at the inside surface of a cylindrical supporting body as a web and substantially continuously drawing it up. CONSTITUTION: This method for producing a nonwoven fabric comprises piling (most preferably 5-50 piled layers) fibers (suitably a sponge type fibers, or the like) conveyed by a high speed fluid (suitably a gas consisting mainly of steam) as a web 10 at the inside surface of a cylindrical supporting body 7, and substantially continuously drawing up the web (optimally at approximately >=3,000 m/min drawing up speed) to obtain the objective nonwoven fabric. Further, the objective nonwoven fabric is suitable for a cleaner, wiper, or the like, excellent in uniformity of its unit weight and strength, also has a small loss in its ear part and is easy for changing its thickness and unit weight. |
