“…Since silk fibroin has the extraordinary characteristics mentioned above and is expensive due to a complex production process and high market demands, besides, using silk fabrics wastes may decrease breeding of silkworms, many scholars have carried out research related to the recycling and reuse of silk. To more effectively recycle and reuse waste silk, certain scientists treated waste silk by impregnation and melting without damaging the internal molecular composition to prepare composites [33,34,35,36]. Certain researchers found methods to destroy the molecular structure of waste silk by high temperature and high pressure or chemical reagent treatment, and successfully obtained silk sericin or fibroin protein [37,38].…”

With excellent biocompatibility and biodegradability, silk fibroin has been developed into many protein materials. For producing regenerated silk fibroin (RSF) fibers, the conformation transition of silk fibroin needs to be thoroughly studied during the spinning process. Since the many silk fabrics that are discarded comprise an increasing waste of resources and increase the pressure on the environment, in this paper, waste silk fiber was recycled in an attempt to prepare regenerated fibroin fiber by dry-wet spinning. Ethanol was the coagulation bath. The rheological properties of all the RSF solutions were investigated to acquire rheology curves and non-Newtonian indexes for spinnability analysis. Four stages of the spinning process were carried out to obtain RSF samples and study their conformation transitions, crystallization, and thermal properties by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction, and differential scanning calorimetry. Quantitative analysis of the FTIR results was performed to obtain specific data regarding the contents of the secondary structures. The results showed that higher concentration spinning solutions had better spinnability. As the spinning process progressed, random coils were gradually converted into β-sheets and crystallization increased. Among the different influencing factors, the ethanol coagulation bath played a leading role in the conformation transitions of silk fibroin.
