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.
Every metre of test cloth is rigorously inspected to ensure that you receive faultless material.
Supplied the metre or as crocking squares (cut pieces) - 5 x 5cm with straight or gimped edges.
We supply European (ISO) and American (AATCC) material. (The specifications are different and are not interchangeable.)
I visited James Heal's premises several years ago and was impressed by their in-house Test Materials centre, and the strict quality assurance procedures their team followed to produce the best quality products
Use a James Heal Grey Scale to give an accurate assessment of colour transfer to the crocking cloth.
