3 PrInciple
Specimens of the textile are rubbed with a dry rubbing cloth and with a wet rubbing cloth. The machine provides two combinations attesting conditions through two alternative sizes of rubbing finger: one for pile fabrics; one for solid colour or large print fabrics.
4 Apparatus
4.1 Suitable testing device for determining the colour fastness to rubbing, using a reciprocating straight line rubbing motion and two alternative sizes of rubbing fingers.
