  • Multiaxial nonwoven fabric
    Patent number: 5338593
    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.
    Type: Grant
    Filed: November 29, 1993
    Date of Patent: August 16, 1994
    Assignee: Polymer Processing Research Institute Ltd.
    Inventors: Yasuo Sasaki, Haruhisa Tani, Yuuki Kuroiwa, Setsuya Tsuyama
