Colour Fastness of Leather to Rubbing

Author: Released in:2019-07-26 Click:442

EN ISO 11640 / IUF 450:
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.

Method:
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.
