Rubbing fastness shows how much dye transfers from the fabric to a white material by rubbing, dry or wet. It is tested with a crockmeter under ISO 105 X12 and graded from 1 to 5. Wet rubbing is usually weaker than dry, often by a full grade, because moisture releases unfixed dye.
The problem occurs most often on dark colours, neon and pigment dyeing, where clothes can stain skin, bags or seats. A grade of 4 dry and 3 wet is a commonly used starting point, but it depends on the customer and the product. Ask for both results separately.
