In carpet terminology, what does 'crocking' specifically refer to?

Crocking specifically refers to the phenomenon of dye transfer from the surface of a carpet when it is wet. This occurs when moisture causes the dyes used in the carpet fibers to loosen and transfer to other surfaces, such as other fabrics or even the carpet itself. This is particularly important for cleaning technicians to understand because it can lead to unwanted staining or discoloration on adjacent fabrics or areas of the carpet when cleaning with water or cleaning solutions.

Understanding crocking is crucial for carpet care and preservation, as it highlights the importance of using appropriate cleaning methods that minimize moisture exposure to the carpet's dyes. Additionally, being aware of the risk of crocking allows professionals to take preventative measures, such as testing for colorfastness before cleaning, ensuring that the carpet does not experience dye bleed during the cleaning process.
