Abstract (en)
The present invention relates to a fiber structure including coil-shaped crimped fibers (a) and non-coil-shaped crimped fibers (b), the fiber structure having an entangled part (A) including the coil-shaped crimped fibers (a) and entangled parts (B) including the non-coil-shaped crimped fibers (b), at least one distance between the entangled parts (B) in a machine direction of the fiber structure being less than the apparent average fiber length of the coil-shaped crimped fibers (a).
