No terms and definitions are listed in this document.
4 Principle
Specimens of the textile are rubbed with a dry rubbing cloth and with a wet rubbing cloth. The staining degree of the rubbing cloths is assessed using the grey scale for assessing staining. The crocking tester provides two combinations of testing conditions through two alternative sizes of rubbing finger: one for pile fabrics and one for solid colour or large print fabrics.
