Abstract A stretchable textile-like fabric comprising at least one layer of nonwoven fibers hydroentangled into a diamond shaped structure so that a substantial number of fibers are oriented equally on all sides of the diamond. This fiber orientation results in a balanced fabric structure. Subsequent to entangling the fibers, they are compacted so as to arrange the fibers into a series of wave-like configurations. The combination of the diamond shape fabric structure and the wave-like configurations of the fibers permits multi-directional stretch in the fabric when tension is applied. Additionally, when the tension in the fabric is released, the inherent memory of the fibers causes the fabric to return to its original form without substantial permanent deformation.
A stretchable nonwoven fabric comprising at least one layer of fibers hydroentangled to form a diamond shaped structure, said diamond structure having a substantial number of fibers on all sides of the diamond to form a balanced structure, said fibers being subsequently compacted so as to have a series of wave-like configurations.
