(pronounced pees DYE-ing)

Primarily used for solid color fabrics, piece dying is the least expensive method of dyeing textiles. In this method, a continuous piece/bolt of dry cloth is passed full-width through a trough of hot dye solution. The textile then goes between padded rollers that squeeze in the color evenly and removes the excess liquid. In one variation of this basic method, the fabric, in a rope-like coil, is processed on a reel that passes in and out of a dye beck or vat. Because the dye is not a part of the yarn, piece dying can often result in crocking.
