ABSTRACT
The three dimensional woven fabric is a single fabric structure in which the constituent yarns are theoretically inclined in a three mutually perpendicular directions. Orthogonal multilayer interlock structures are produced in a way that warp yarns of a layer are used to bind the other layers. Since warp yarns are used to connect the layers, no dedicated binding yarns are used. Fabrics consisting of two or more single-layer, connected to each other at some points whose distance from each other in the warp and weft directions is substantially greater than the basic weave repeat are called multilayer stitched fabrics. In orthogonal through thickness structures, some warp yarns from the first and last layers are used to bind all the layers present in the fabric. Multilayer angle interlock structures are produced in a way that binding yarns passed from the fabric layers at a certain angle to bind all the layers.
