Scouring machines of wool depend on the kind of wool to be scoured i.e. raw wool, hank form or woven fabrics. Scouring of wool can be carried out in batch or continuous process, aqueous or solvent media and rope or open width form. 

Woollen and worsted yams, unless dry spun contain significant amount of lubricating oil and are usually scoured in hank form in a continuous scouring machine.
