11/20 · The highly concentrated spider silk protein solution is secreted and stored inside the spinning gland. Upon initiation of thread formation, the solution is directed through a narrow ion exchange channel, in which a phase separation process takes place.

Pyriform glands are responsible for producing silk fiber for attachments, while tubuliform glands provide spiders with spider silk for 

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 is considered one of the best silk fibers, with remarkable strength and extensibility (3). However, the large-scale production of 

Just like a tiny cable, each silk fiber is entirely composed of parallel nanostrands, which they measured to be at least 1 micron long. That may not sound very lengthy, but on a nanoscale, it's at least 50 times as long as these fibers are wide—and researchers believe they could stretch even further.

Spider's web made of silk is being used in this process to make textiles. Spiders have different glands to produce variety of silks with versatile properties making it suitable for various routine and differed uses. Routine Usage of Spider Silk:

Spiders make many kinds of silk. The best known is dragline silk which the spider uses in web construction and also for "hanging around". Dragline silk consists of proteins called spidroins. These are made in the spider's silk glands as a thick paste that is drawn into fibers during spinning. Once spun, the silk is strong and very tough.

Spiders produce amazingly strong and lightweight threads called draglines that are made from silk proteins. Although they can be used to 

Spiders make silk material from their fluids and combine it with proteins to create silk. A spider will usually start by collecting fluid from its abdominal glands. Then, they mix this up with protein fibers in the thorax. Here they release more than one kind of fiber at a time, thus producing silk.

Only the females of this species produce the silk, which they weave into webs. The webs glow in the sunlight and it has been suggested that this is meant either to attract prey, or to serve as a camouflage. A red-legged golden orb-web spider (Nephila inaurata).

Spider silk is composed of protein fibers secreted by glands in the abdominal (or rear) part of spiders. The raw material of silk is a liquid protein that passes through the spinnerets (silk
