Color bleeding and crocking. Are they the same? No! KNOW YOUR FABRICS SERIES
CROCKING Crocking is the "color-transference" of a fabric. It is what happens when there is "rubbing". There are two types of crocking - dry & wet. In dry crocking, a piece of a dry white cloth is rubbed against the dyed fabric in a crock-meter. After a specific time (or number of rubs), the white fabric will have some stain from the dyed fabric. The stain is measured on a scale of 1 to 5, 1 being "very poor" & 5 being "excellent". The same method is used for wet crocking with a damp white cloth. Most fabrics (except white) crock - some less, some more. KNOW YOUR FABRICS SERIES
BLEEDING Bleeding means "What happens when the dyed fabric is washed?” Dark colors like black and red will bleed more in comparison to a tan or light grey. There are other factors like temperature of the water, washing time, type of detergent used, etc. that can affect the color bleeding in a fabric. There are different standards set by ISO & AATCC to determine the various levels of color bleeding. KNOW YOUR FABRICS SERIES
