Colour Fastness of Leather to Rubbing

2019-07-26 10:27
This method is intended for determining the transfer of colour and the behaviour of the surface of a leather on rubbing with an undyed wool felt.
The felt may become coloured through transfer of any kind of coloured matter, e.g. finish, pigment, dyestuff and buffing dust.
The side of leather to be tested is rubbed with pieces of standard wool felt under a given pressure with a given number of forward and backward motions. The wool felts can be either dry, wetted out in water or wetted with a solution of artifical perspiration at pH 8.
The change in colour of the felt and of the leather are assessed with a standard Grey Scales. Any other visible change or damage of the surface of the leather should be also reported.
