1 Million Spiders Make Golden Silk for Rare Cloth

A rare textile made from the silk of more than a million wild spiders goes on display today at the American Museum of Natural History in New York City.
To produce this unique golden cloth, 70 people spent four years collecting golden orb spiders from telephone poles in Madagascar, while another dozen workers carefully extracted about 80 feet of silk filament from each of the arachnids. The resulting 11-foot by 4-foot textile is the only large piece of cloth made from natural spider silk existing in the world today.
“Spider silk is very elastic, and it has a tensile strength that is incredibly strong compared to steel or Kevlar,” said textile expert Simon Peers, who co-led the project. “There’s scientific research going on all over the world right now trying to replicate the tensile properties of spider silk and apply it to all sorts of areas in medicine and industry, but no one up until now has succeeded in replicating 100 percent of the properties of natural spider silk.”
Peers came up with the idea of weaving spider silk after learning about the French missionary Jacob Paul Camboué, who worked with spiders in Madagascar during the 1880s and 1890s. Camboué built a small, hand-driven machine to extract silk from up to 24 spiders at once, without harming them.
“Simon managed to build a replica of this 24-spider-silking machine that was used at the turn of the century,” said Nicholas Godley, who co-led the project with Peers. As an experiment, the pair collected an initial batch of about 20 spiders. “When we stuck them in the machine and started turning it, lo and behold, this beautiful gold-colored silk started coming out,” Godley said.
