Spider silk - Wikipedia
Spider silk is a protein fibre spun by spiders. Spiders use their silk to make webs or other structures, which function as sticky nets to catch other animals, or as nests or cocoons to protect their offspring, or to wrap up prey. They can also use their silk to suspend themselves, to float through the air, or to glide away from predators. Most spiders vary the thickness and stickiness of their silk for

How is spider silk made? - YnFx
The process by which spiders produce silk is called pultrusion wherein the spiders pull the silk thread from the silk-producing gland. The silk-making glands resemble the spinneret which consists of a number of tubes. These glands contain a watery solution that is nothing but silk protein.

Spider Silk - an overview | ScienceDirect Topics
Andersson et al. ( ) have produced spider silk by a much closer process to the one that spiders use. Spider silk proteins are made of an N-terminal domain and a C-terminal domain bracketing a region of repeated amino acids, which make the silk strong ( Hagn et al., ).
