| The tensile properties and fracture surfaces of N-methylmorpholine-N-oxide (NMMO) regenerated silk fibroin fibers produced with a range of draw ratios has been characterized and related to their microstructure with data obtained from Raman spectroscopy and birefringence measurements. The spinning process allows control of two different draw ratios, coagulation and post-spinning, and it has been found that the microstructure and the properties of the fibers can be modified by the proper combination of both draw ratios. NMMO regenerated silk fibroin fibers subjected to post-spinning drawing yield tensile properties comparable to other regenerated fibers and strain at breaking comparable to natural B. mori silk fibers. Tensile strength, however, is still significantly lower than that of natural fibers. | |
