ABSTRACT:
A multiaxial nonwoven fabric is disclosed which is comprised of a selected warp material and a multiplicity of selected continuous yarns assembled in a specified lay pattern and bonded on to the warp material. Each of the yarns is oriented in a scalene or right-angled triangle shape, and the resulting yarn assembly is built of intersections at least in warp, weft and oblique axes, whereby structural strength and dimensional stability are greatly improved. A method and an apparatus are also disclosed for producing the fabric.
