Silk throwing

Silk throwing is the industrial process where silk that has been reeled into skeins, is cleaned, receives a twist and is wound onto bobbins. The yarn is now twisted together with threads, in a process known as doubling. Colloquially silk throwing can be used to refer to the whole process: reeling, throwing and doubling. Silk had to be thrown to make it strong enough to be used as organizine for the warp in a loom, or tram for weft.
