Crocking Cloth/Cotton Lawn

For Testing Colour Transfer

Crocking cloth, also known as cotton lawn or rubbing cloth, is used in a Crockmaster (Crockmeter) to check the amount of dye transfer, following a dry or wet rub fastness test. The dyed sample is rubbed, under controlled conditions, against the white crocking cloth. Subsequently, the degree of colour transfer is evaluated using a Grey Scale for assessing Staining.
