Airbrush Aniline Dye On Veg Tan?

[DavidL]

First, is this bag dyed with aniline dye or oil dyes? If it is aniline dye where would this be sourced in larger sizes. Martin aniline dyes come in small containers less than 100ml that I believe can make something like 1:4 ratio, so 400ml (i could be wrong).

It doesnt show in the video any finish added, the finish step could have be taken out of the video or does aniline dye not require finishing since it adheres better, resulting in no dye bleed?

How would I go about making semi - aniline, is there something I need to add to regular aniline.

Oil dye vs aniline dyed vs this product below -

Is there an upside to using oil dyes, the most popular out of the bunch. Can this furniture stain work as a stand alone dye rather than the typical cover up.

- A sort of stain. Looks to be like oil dye without as much dye bleed. Edited July 18, 2014 by DavidL

Help in what way? I am somewhat curious about analine dying leather. I already have a resident cloth dying expert, as well as the facilities to do that type of thing, I have little info on analine dying of leather.

from my novice tanneries experience , the aniline dyeing is something you can't do at home or a workshop , the dye is put in a drum , the type of dye that colors the leather from flesh side to the grain side across

Aniline is just dyed, where as semi-aniline has a top finish on it. Aniline dyed leather with resolene on it would be semi-analine.

That is not much help at all. All of the commercial leather manufacturing processes have their roots in cottage industry, and by definition started in a home workshop........

I have found that analine dyes can indeed be used at home, and are commonly used in the book-binding and conservation world.

They can be airbrushed, however dye particles may be an issue with clogging.
