Definitions
- the invention relates to solid tannin / retanning preparations, a method for their production, their use for tanning and retanning as well as with them tanned and retanned leather and furs.
- Retanning means that Aftertreatment of pre-tanned (generally chrome-tanned) leather to Color, levelness, softness, fullness and behavior against water (hydrophobicity) to optimize and fix tannins.
- pre-tanned generally chrome-tanned
- Tanning, retanning and dyeing in particular are usually carried out in different ways so-called tanning drums using aqueous tanning / retanning solutions or dispersions or dye solutions carried out.
- Most of the tannins and tanning agents used are powdered Solid added to the tanning tanks (fleets), which makes handling easy and minimal storage space guaranteed.
- To rationalize these steps have been mixtures of various powdered tannins in the past and tanning aids are manufactured, with which the tanning process by saving of path and add operations to be simplified.
