The Triax I used to use was not woven at all, it was stitched together from layers of unidirectional roving. They called it knitted, but no knitting process was involved, it was all chain stitch (stitching could easily be unravelled) using parallel transverse lines of probably polyester thread about 10mm apart if I remember correctly. Stitching tended to stand up a little on hand layup. Fibres had some freedom to slide in the stitches, which allowed some ability to form over 3D curves. Edges were stepped back for the overlap, but tended to have a bit sudden thickness change at an end overlap.
Cheers,

They are both cloth. All cloth is woven. Just some more than others.
Triax is 3 layers of uni knitted together with fine polyesyer thread. Double bias and biax are 2 layers knitted together. Uni is one layer, knitted to keep the fibres aligned. Triax is hard to get around tight corners, but on flat surfaces it is little or no different to 3 layers of uni or one of biax/double bias with a layer of uni on top.
