Crocking is tendency of a fabric or paint to give off color when the surface is rubbed. For fabrics, crocking may occur when it has excess dye or has been improperly dyed. For paintings, crocking may occur when the pigment to binder concentration is high. [1] Textiles and garments with fabric color or design that is lighter on the reverse side is likely to be fabric that have been subject to pigment print or surface dye. These methods of prints and dyes, when used on fabrics are susceptible to dye crocking. Dye crocking can be the result of color loss by friction, abrasion and mechanical action.[2]

Discussion[edit | edit source]

A crockmeter is used in physical testing of textiles to evaluate the degree of transfer. The test used is a standard textile test, either a Canadian General Standards Board test or the American Association of Textile Chemists and Colorists test. A manufacturer would use it to see if the textiles met standards for care labeling. A fabric that crocks will stain the muslin test piece and the stain is measured by the grey scale, the lightness or darkness on the muslin test piece. Ideally textiles shouldn't crock.
