Disclosed are a process for producing a tubular nonwoven fabric and tubular nonwoven fabrics produced by the same. In the process, a web is formed on a first rotating cylinder by catching fibers carried to the surface of the first rotating cylinder by a fluid, the web is transferred to a second rotating cylinder, a tube of the transferred web is formed on and around the second rotating cylinder, and the tube is drawn in the axial direction of the second rotating cylinder to form a tubular nonwoven fabric. The tubular nonwoven fabric with a high unit weight can be produced without elongating or breaking the nonwoven fabric, and the diameter of the tubular nonwoven fabric can be freely changed. |
