Noobing: A Nonwoven 3D Fabric-forming Process Explained

A unique nonwoven 3D fabric-forming process, designed to bind a set of linear yarns that is arrayed in either uniaxial or multiaxial orientation, was identified, characterised and termed noobing five years ago. The produced 3D fabric, usually intended for composite materials application, is layerless and comprises crimpless yarns. This process has been mistaken to be 3D-weaving and multiaxial/3D-knitting. It is thus necessary to explain its non-compliance with the well-established technicalities of both these processes. A dozen patents are therefore exemplified and discussed collectively according to a new classification of this noteworthy process, for the first time. The factors causing misrepresentation of this process, such as its incorrect technical description and patent classification, are also considered to complement the discussions.
