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
