Used in a Crockmaster (Crockmeter) to check the amount of dye transfer, following a dry or wet rub fastness test

Enquire

Customers can use our crocking cloth’s and cotton lawns alongside our Crockmaster (Crockmeter) instrument as a way of assessing the amount of dye transfer following the completion of either a dry or wet rub fastness test. A range of materials can be assessed in this manner, including carpets, laminates and printing inks as well as coated and painted surfaces.

The fabric to be sampled is rubbed under controlled conditions against the white crocking cloth. The subsequent degree of colour transfer is then evaluated via the use of a grey scale, as a method for evaluating staining and is then graded.

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.
