The apparent variability of silkworm (Bombyx mori) silk and its relationship with degumming

As spun silkworm (*Bombyx mori*) silk fibers were compared in terms of their tensile behavior and microstructure with fibers subjected to different degumming treatments. Fibers were initially retrieved by forced silking directly from the worms and, …

Minor Ampullate Silks from Nephila and Argiope Spiders: Tensile Properties and Microstructural Characterization

The mechanical behavior and microstructure of minor ampullate gland silk (miS) of two orb-web spinning species, Argiope trifasciata and Nephila inaurata, were extensively characterized, enabling detailed comparison with other silks. The similarities …

Relationship between microstructure and mechanical properties in spider silk fibers: two regimes in the microstructural changes

The relationship between microstructure and mechanical properties has been investigated in *Argiope trifasciata* dragline silk fibers (major ampullate silk, MAS) by X-ray diffraction, Raman spectroscopy and tensile testing. We have analyzed three …

Bioinspired fibers follow the track of natural spider silk

The mechanical behavior and microstructure of bioinspired fibers spun from solutions of recombinant spidroin-like proteins were extensively characterized, and compared with those of natural spider silk fibers. It is confirmed that high performance …

Old silks endowed with new properties

High-performance regenerated silkworm Bombyx mori silk fibers with new properties that mimic those of spider silk can be produced through a wet spinning process modified with an immersion postspinning drawing (IPSD) step. IPSD fibers show the ability …
