Usually, the term refers to a combination of fibres of the same generic class in which some of the fibres have been modified to change their affinity for dye so that they dye more deeply or less deeply than standard fibres. However, differential dyeing can also occur when blends of different generic fibres types, such as cotton and polyester, are used.
