Wartime industrial manual for cloth printing and dying by IG-Farben

Lot of pre war and wartime cloth coloring and printing manuals by IG-Farben. Mainly focussed on the method of dying the cloth and the correct procedures. The manuals contain a vast number of set colour swatches with coherent dye formulas. These set colours are also widely used within the German army and as such set the basic standard for a lot of wartime printed and dyed uniforms. As there is a lot of pages, probably over 1000 with information, there is probably more then I have gotten to read. Although not directly military; this sheds an birds eye view on the background of printing camouflage colours and dying various fabrics ranging from wool to rayon with the appropriate techniques.
