Comprehensive Study on the Formation of Higher-Order Structure of <i>Bombyx mori</i> Silkworm Fibers: Influence of Sericin Fractions, Modulation of Spinning Process, and Metal Ion Interactions

Low Spinnability of Sericin Dominates the Forcibly Spinning Speed

“…The sericin M fraction will work as a crystallization inhibitor against silk 2 crystal modification of fibroin, and the preferential silk 2 crystal modification of fibroin H-chains at room temperature is considered to be guided by sericin P fraction like a nucleation agent. The detail has been reported elsewhere[19].…”
