Figure 7. Stitch-bonded type of warp knitting.

Schematic representation of face (A1) and reverse (A2) sides of composite. Stitch is blue (A). Composite made out of carbon fibers bonded with white yarn (B), face (B1) and reverse (B2) sides of composite. Examples for stitch-bonded fabrics made by using the warp offset device (C-F), two warp layers crossing (C), reinforcement for triangular perform (D), threads with reserve length (E) and segment of a circle (F). Reprinted with permission from³⁵. 3D printed PCL construct that could work as a stabilization “jacket” for knitted yarns (G). Prior to forming the final shape, the yarns can be combined with pillars of the “jacket” using stitch-bonded type of warp knitting.
