Toward spinning artificial spider silk.
Spider silk is strong and extensible but still biodegradable and well tolerated when implanted, making it the ultimate biomaterial. Shortcomings that arise in replicating spider silk are due to the use of recombinant spider silk proteins (spidroins) that lack native domains, the use of denaturing conditions under purification and spinning and the fact that the understanding of how spiders contr...
متن کاملStretching of supercontracted fibers: a link between spinning and the variability of spider silk.
The spinning of spider silk requires a combination of aqueous environment and stretching, and the aim of this work was to explore the role of stretching silk fibers in an aqueous environment and its effect on the tensile properties of spider silk. In particular, the sensitivity of the spider silk tensile behaviour to wet-stretching could be relevant in the search for a relationship between proc...
متن کاملmatrix-fibril morphology and structure of polyblend fibers in melt spinning process: a review
the mechanism and the parameters affecting the matrix-fibril morphology in melt spun polyblend fibers are discussed. the properties of polymeric blends depend considerably on their final morphologies. blending of two miscible polymers, normally gives rise to formation of a single-phase morphology while blending of two immiscible polymers can create a two or three (in case of using compatibilize...
متن کاملStraining flow of a micellar surfactant solution
We present a mathematical model describing the distribution of monomer and micel-lar surfactant in a steady straining flow beneath a fixed free surface. The model includes adsorption of monomer surfactant at the surface and a single-step reaction whereby n monomer molecules combine to form each micelle. The equations are analysed asymptot-ically and numerically and the results are compared with...
متن کاملSilk Spinning in Silkworms and Spiders
Spiders and silkworms spin silks that outcompete the toughness of all natural and manmade fibers. Herein, we compare and contrast the spinning of silk in silkworms and spiders, with the aim of identifying features that are important for fiber formation. Although spiders and silkworms are very distantly related, some features of spinning silk seem to be universal. Both spiders and silkworms prod...
