Principle of color fastness to crocking

According to the crockmeter test method, strapping dry or wet cotton cloth on the surface of the friction head of the machine with a metal buckle, make the sample rub with the white crockmeter test cloth for friction, contrast the gray card, compare the color degree of the white cotton cloth for friction with the gray-colored grade gray sample card, judgement the grade of colorfastness to crocking.

Significance of crocking test

Fabric friction can exist in our real life in various ways, such as the friction between fabric and lining when people wear clothing, friction in various splicing parts, friction when sitting on objects, and so on. These conditions are likely to affect the appearance of the garment and even endanger our health because of the poor rubbing fastness of the fabric, resulting in color transfer. The fastness to rubbing is closely related to our life and should be paid enough attention to.

What is a crocking meter?

The product crockmeter is a kind of test instrument that uses the test simulation environment to test the solid degree of the sample color. From the beginning of the manual friction tester to the present motorized crockmeter, from the testing of textiles to the testing of leather, colour fastness to rubbing test method become more and more(for more information on crockmeter testing, please refer to the crockmeter Wikipedia).

Comparison of crockmeter

At present, different countries adopt different crocking test standards. For example, the moisture content of wet friction in AATCC8 test method should be 65%, while the other standards are 95%~100%, and so on. The specific parameters of the different criteria are shown in the following table:

Q: What’s the difference between rubbing and crocking?

A: There is no exact distinction between rubbing and crocking. You can refer to the ISO 105-X12:2016-Colour fastness to rubbing and AATCC test method 8-Colorfastness to Crocking.


Q: Is the weight on top of TF411 can be taken off and measured as we need to calibrate?

A: No. The weight above is just an aggravating weight. The total weight of the friction head is 9N. It contains the weight of the entire arm. We will check the weight before delivery and you cannot weigh it separately.


Q: Is the friction speed of TF411 adjustable?

A: No. Only one speed is specified in the standard: 60 rpm.
