Tougher than any man-made material, spider silk fiber is a combination of strength and elasticity, no other material can actually combine these two features. Either material is strong or it is elastic but spider silk is both. Five times stronger than steel, spider silk when combined up to a certain amount is actually much more stronger and flexible than steel.
If we take a thumb thick spider fiber, we can actually get a jumbo jet holding up without tearing it apart. It can withstand hundreds of tons of load in full speed without breaking.
Spider silk is a protein fiber spun by spiders. Most of the spider silks have their own exceptional properties but ‘dragline spider silk’ in particular have exceptional mechanical properties. It exhibit a unique combination of high tensile strength and ductility which enables it to absorb a large amount of energy before breaking.
Replicating the spider silk has been difficult but not anymore. A biomaterials lab at Bayreuth University in Germany claims with a DNA sequencing breakthrough manufacturing spider silk fibre is no longer a fantasy.
The best silk producers are orb-weaving spiders. They have different types of silk with different properties. These spiders have a very rare characteristic in their silk. Scientists find dramatic differences in these spider’s silk fibre concerning the mechanics and other properties.
Scientists at AMsilk (leading producer of biosteel fiber) are using a bacteria which only try to grow and Scientists are exploiting that, by feeding them, by providing them perfect conditions to live and when they multiply, their way of living is changed. Scientist trigger them so that they stop proliferating and produce protein that is needed. This protein is turned into a white powder after purification.
AMsilk turns that protein into fiber by spinning which later is turned into yarn and then into fabric out of the material.
Adidas used this fabric to create a concept shoe and Omega made a special edition watch strap with this fabric.
Dr. Lin Roemer, Cheif Technology Officer at AMsilk said
We are living in a time where materials made from proteins will become more important every day
