Silk throwing

Silk industry (reeled silk throwing) Winding thread from skeins on to bobbins.

Silk throwing is the industrial process wherein 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.[1] Silk had to be thrown to make it strong enough to be used as organzine for the warp in a loom, or tram for weft.[2]
