Progress of studies on regenerated protein fiber of silkworm silk and spider silk

The properties of silkworm silk and spider silk are excellent,and obtaining regenerated silkworm silk and spider silk with good performance through artificial methods has been a hot field of research to domestic and overseas scholars.However,currently the available regenerated silkworm silk and spider silk are not satisfactory.This paper summarizes the studies on regenerated silkworm silk and spider silk,including preparation of spinning solution,wet-spinning and electro-spinning,as well as the impact of spinning conditions on the properties of fibers etc.It also discusses the improvement of the properties of regenerated fibers through pH value adjusmet,alcoholic solution treatment,stretching,and heat treatment.Finally,the paper presents the bright future of regenerated silk fibers,and it is expected to provide useful information for the further studies on artificial silkworm silk and spider silk.
