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.
The different types of silk (major ampullate silk, minor ampullate silk, flagelliform silk, aciniform silk, tubiliform silk, pyriform silk, and aggregate silk) [11] are composed of different types of proteins. Dragline silk is mainly formed by spidroin proteins. It is a type of major ampullate silk and is produced in the major ampullate gland.
The spider silk has a greater tensile strength than steel, and the material is even strong enough to stop a bullet. In terms of everyday usage, spider silk could be a huge game changer when it ...
The tensile strength for the three kinds of silk measured in the Blackledge study was about 1,000 MPa. The ultimate strength reported in a previous study for Trichonephila edulis was 1,290 ± 160 MPa. [22] The tensile strength of spider silk is comparable to that of steel wire of the same thickness.
BioSteel was a trademark name for a high-strength fiber-based material made of the recombinant spider silk-like protein extracted from the milk of transgenic goats, made by defunct Montreal-based company Nexia Biotechnologies, and later by the Randy Lewis lab of the University of Wyoming and Utah State University.

Since spider silk has a variety of potential uses, including in fabrics and biomedical technologies, the sequence motifs for genes coding for this silk in the species have been studied to examine the potential for artificial production. In the study by Lee et al., clones of the genes for this silk were produced and injected into insect cells to ...
Dragon silk combines the elasticity and strength of spider silk. It has the tensile strength as high as 1.79 gigapascals (as much as 37%) and the elasticity above 38% exceeding the maximum reported features of the spider silk. [citation needed] It is reported that dragon silk is more flexible than the "Monster Silk" and stronger than the "Big ...
Textile fibres or textile fibers (see spelling differences) can be created from many natural sources (animal hair or fur, cocoons as with silk worm cocoons), as well as semisynthetic methods that use naturally occurring polymers, and synthetic methods that use polymer-based materials, and even minerals such as metals to make foils and wires.
