Dye works concept

I have done some research for my dye works and formed a concept.  I do not have the resources available that I had for the tannery project, but it is adequate for my purposes.  Local dye works thrived in the late 1800s and early 1900s but by the mid 1900's they were mostly eliminated by large chemical companies.  Prior to the late 1800s dyes were mostly made from natural products such as wood, roots, berries, leaves and bark.  Then the discovery of synthetic dyes became prevalent and essentially eliminated the market for natural dyes.  Since I model the 1939 era my dyeworks uses synthetic dyes, and thus is essentially a small chemical plant.  The use of synthetic dyes created a vastly wider array of colors for dyes.  Below is a photo showing a moderately large early natural dye works that apparently used wood to create their dye products.

In the photo you can see stacks of logs used in the dyeworks.  Since I have not yet found any suitable prototype dyeworks photos for my era I have extrapolated how it might look based on the typical elements found in small chemical plants.  My dyeworks only develops and sells the dyes.  Many of the dyeworks both made the dyes and did the dyeing of cloth.

Different types of cloth require different dye material.  Some examples are silks, cotton, wool, etc.  each has their own properties. The dyes are essentially colors in a solution and require chemicals called mordants to enable them to adhere to the cloth.  Some examples of mordants are tannic acid (from bark for example), sodium chloride and a variety of metal salts.

I made a few rough sketches of structures for my dyeworks and am well along on the first building.  I plan to have a number of external tanks in my dyeworks to add visual interest though most dye tanks would likely be located within the structures.  There will of course also be lots of piping.  I hope to have this first building complete in a few days.  I am not aware of this industry having been previously modeled though it may well have been and I just never saw the models.
