MORDANTING [2 records]

Record 1 2012-06-13

English

Subject field(s)
  • Leather Staining
CONT

In order to fix a basic dye onto chrome leather, a negative charge must be introduced on the leather. This is done by mordanting chrome tanned leather by adding a vegetable tanning material or an anionic syntan. The basic dye will then be very strongly attracted to the "mordanted" fiber, and stable fixation will take place.
