There is disclosed an improved non-woven fabric comprising a layer of staple length fibers and a binder material diffused substantially through the fabric adhering fiber ends together to provide fabric strength. The improvement is based on the binder being arranged in a pattern in segments. These segments running substantially perpendicular to the orientation of the fibers (or the machine direction), and the pattern within these segments have a plurality of repeats within each segment and a repeat of said total segment pattern in alternate segments. The components of this pattern are mutually laterally displaced from each other in sequential segments, at least 80% of the components of said pattern being at an angle of between at least 10 DEG to not more than 70 DEG relative to the orientation of the majority of the fibers (or the machine direction). |
