Tissue engineering requires the ability to design scaffolds with mechanical properties similar to those of the native tissue. Here, B. mori silk yarns are used as a model system to demonstrate the potential benefits and drawbacks of several textile methods used to fabricate tissue engineering scaffolds. Fibers are plied, twisted, cabled, braided, and/or textured to form several geometries with a wide range of mechanical outcomes. Predictable changes in ultimate tensile strength and stiffness are demonstrated following processing and as a function of test environment. The mechanical effects of increasing turns per inch and combining groups of fibers into higher-order yarn structures are demonstrated. Braids, one of the most commonly used textile structures, are shown to be limited by a change in stiffness following the locking-angle and therefore, potentially not the ideal structure for tissue engineering. Cabled yarns appear to allow the most flexibility in mechanical outcomes with a highly organized geometry. Twisted yarns, while more economical than cabled yarns, result in a higher stiffness and lower percent elongation at break than cabled yarns.
