Where very large quantities of one color are to be used, raw stock dyeing is cheapest and best. This type of dyeing has been particularly developed by Bigelow which has the largest raw stock dye house in the country. Ten thousand pounds of scoured wool is an average batch (although batches run as high as sixty thousand pounds) and three separate dyeings of seven large kettles each are required to handle it. The wool is picked once before dyeing.
