This machine is designed to carry out a rub fastness test on the surface of leather to determine the amount of marring of the leather surface or finish, and to assess the amount of color transfer from the sample to the rubbing pad.
The colorfastness is assessed by checking color change of the specimen and staining of the felt after rubbing. Both dry and wet tests can be made by this machine, which has a memory function. It is designed for resistance of shoe upper leather, with and without finishing, against abrasion.
