Spider silk spinning field, the spinneret apparatus of an adult "Araneus diadematus" (garden cross spider) consists of the glands shown below. Similar multiple gland architecture exists in the black widow spider. In order to artificially synthesise spider silk into fibres, there are two broad areas that must be covered. These are synthesis of the feedstock (the unspun silk dope in spiders), and synthesis of the spinning conditions (the funnel, valve, tapering duct, and spigot). There have been a number of different approaches. The molecular structure of unspun silk is both complex and extremely long. Though this endows the silk fibres with their
Winter garden Winter garden A winter garden is a kind of garden maintained in wintertime.
