Spider silk is a protein fibre or silk spun by spiders. Spiders use silk to make webs or other structures that function as adhesive traps to catch prey, to entangle and restrain prey before biting, to transmit tactile information, or as nests or cocoons to protect their offspring.
Kraig Biocraft Laboratories, Inc. (www.KraigLabs.com), a reporting biotechnology company is the leading developer of genetically engineered spider silk-based fiber technologies. The Company has achieved a series of scientific breakthroughs in the area of spider silk technology with implications for the global textile industry.
Kim Kraig Thompson, a retired lawyer, invented the protein expression platform in 2002, which would become the basis for Kraig Lab's work with spider silk. [3] He founded Kraig Biocraft Laboratories in April 2006 to develop and commercialize spider silks and other high-performance polymers gene and sequences using platform technology in combination with genetic engineering concepts.
A classic circular form spider's web Infographic illustrating the process of constructing an orb web. A spider web, spiderweb, spider's web, or cobweb (from the archaic word coppe, meaning 'spider') [1] is a structure created by a spider out of proteinaceous spider silk extruded from its spinnerets, generally meant to catch its prey.
The silk is a complex form of protein fiber that starts off as a protein-rich liquid and then dries into solid filaments, thanks to spinnerets, an external portion of spider glands.

Dragon silk is far more flexible than Kevlar (the material used by US Army to develop body armor). Its flexibility is 38% higher than normal spider silk and is noticeably more flexible than the "Monster silk" from the same laboratory. In percentage, Kevlar's flexibility is 3% and dragon silk's flexibility is 30% to 40%.
