Spiders produce silk from structures called spinnerets, which are glands at the base of their abdomens. Spiders produce a wide variety of silk and each type has its own particular use. For instance, the strong and elastic silk is used to build the foundation of a web; sticky threads are produced to trap prey; tough

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.

Here, we report on an artificial spider silk produced by the water-evaporation-induced self-assembly of hydrogel fibre made from polyacrylic 

What is Spider Silk? 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-spinning organs). It becomes dry as it comes out from the abdomen of the spider's body, and forms a thread.

Spiders produce amazingly strong and lightweight threads called draglines that are made from silk proteins. Although they can be used to manufacture a number of useful materials, getting enough of

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., ).

The silk starts as a liquid stored in internal silk glands before hardening into a solid form, according to the Smithsonian magazine(Opens in a 

Spider's silk is made up of chains of amino acids. In other words, it is simply a protein (see How Food Works for details on amino acids and proteins).

They found that each strand—which is 1000 times thinner than a human hair—is actually made up of thousands of nanostrands, only 20 millionths of a millimeter in 

The truth is, it depends on how you measure it and what condition the silk is in. Silk absorbs moisture, a property given it by the large amount of the amino acid Alanine it contains. The more water that spider silk contains, the less brittle and the more elastic it is. The range is from about 30% to 300% elasticity - depending on the amount

Spider silk is a fiber made up of proteins. Each spider typically spins several different forms of silk. Some spiders use one form of silk to spin the webs they use to catch their prey and then use a different silk to wrap the prey up in a tidy bundle.

Researchers are involved has developed a bioinspired method that for the first time will allow researchers to spin artificial silk fibers as 

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).

To solve that problem, they devised a hybrid made with two natural silk proteins from different spiders. Sure enough, the hybrid protein behaved 

A spider's silk-making proteins, called spidroins, form in its abdomen as a dense liquid. Spinnerets, body parts on the spider's rear end, spin 

The process of producing spider silk begins with special glands in the abdomen called “spinnerets.”. These are connected to spigots which produce the “spinning” fluid that will

Spiders have silk-producing glands in their bodies, specifically in their abdomen. In these glands they have the chemical components already put together to produce silk, but it's in a liquid form. When a spider wants to produce a strand of solid silk, they have to pull this strand of silk out of their bodies.

7/30 · Spider silk is composed of protein and is biodegradable. Spider silk is more resistant to high temperatures. It exhibits thermal stability below 200°C and starts to turn yellow at above 300°C. Spider silk is resistant to low temperatures, and it still remains at minus 40°C. Elasticity, it hardens only at lower temperatures.

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.
