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%.
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.
Spiders make spider silk for various purposes such as weaving their webs, protecting their eggs or as a safety line. The amphipod Peramphithoe femorata uses silk to make a nest out of kelp blades. Another amphipod, Crassicorophium bonellii, use silk to build shelter. Carp produce fibroin units, a component of silk, to attach their eggs to rocks ...
Spider silk structure: crystalline beta-sheets separated by amorphous linkages. Silks have a hierarchical structure. The primary structure is the amino acid sequence of its proteins (), mainly consisting of highly repetitive glycine and alanine blocks, [4] [5] which is why silks are often referred to as a block co-polymer.

Argiope flavipalpis adult female An Argiope juvenile female spiders both same genus on the stabilimentum at the center of the web. A stabilimentum (plural: stabilimenta), also known as a web decoration, is a conspicuous silk structure included in the webs of some species of orb-web spider.
Silk taken from various species has been used since ancient times, either in its natural state or after some form of preparation. Spider webs were used as a wound dressing in ancient Greece and Rome, [2] and as a base for painting from the 16th century. [3] Caterpillar nests were used to make containers and fabric in the Aztec Empire. [1] [4]
Silkhenge structures are a means of spider reproduction used by one or more currently-unknown species of spider. It typically consists of a central " spire " constructed of spider silk , containing one to two eggs, surrounded by a sort of fence of silk in a circle.
