We may soon see artificial silk products if its as simple as Scientists May Have Solved the Secret of Silk describes:
Scientists say they may have worked out how spiders and silkworms are able to produce such strong fibers to spin their webs and cocoons.

Kaplan and his team say the secret to silk production lies in how spiders and silkworms control silk protein solubility in their glands.“The entire process is controlled by the amount of water, which is so simple,” he told Reuters.
“The organism dumps protein into the gland but as it does that, it regulates how much water it leaves in there. That controls the entire process.”
