Re-generated silk fibroin (RSF) with various concentrations including 8, 10, 12.5 and 13% (w/w), was dissolved in N-methyl morpholine N-oxide (NMMO) to prepare spinning solutions. The effect of several coagulants such as methanol, ethanol and 1-propanol, and temperatures of spinning including 95, 110 and 120 °C, on the wet spinnability of the silk fibroin solutions were investigated. Tenacity at break of undrawn fibers, which were produced by various concentrations and coagulants, were
