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.

A fur-like synthetic sheet material is provided with numerous superfine synthetic pile fibers having fineness or thickness of about 0.0001 to 0.4 denier. The pile fibers, which are comparatively long, have crimps and are formed into bundle groups, while the crimps of the pile fibers are substantially in phase within each bundle.
