Painting Cloth Seats - Dyeing Fabric
I've run across this a lot in my travels, a customer asks "Can you dye my cloth seats?" My answer to them is, "No, I can't really dye your seats. What I can do is paint your seats." Dyeing and painting cloth are two very different things. Dyeing cloth consists of immersing the entire fabric in a dye solution, soaking it through and through for a period of time, then rinsing the excess dye away. Rinsing removes any excess dye left so not to transfer onto something that you don't want dyed like your clothes. Dyeing cloth is a more permanent way to change a color. The dyes actually penetrate the fibers of the fabric. Painting cloth consists of spraying a solution of colored pigments and a binder of...

Wool Dyeing - Equipment Needed For Advanced Methods
This is the second in a series of articles on the subject of dyeing wool, using the three primaries, metric measurement, liquid dyestock, and percentage-based formulas.

The History Of Dye
Tie dye - the history of dye...People have practiced the art of tie dye for as long as they have been adding color to cloth. In ancient times, natural dyestuffs were used such as beetroot and lichen, but colors were variable and colors faded over many washes. Large quantities of natural material are needed to generate a small quantity of color. For example, it takes approximately 3kg of lichen to make enough dye to color a T-shirt. Considering it takes lichen years to grow just a few centimeters, the cost to the environment is fairly high, even though the by-products are bio-degradable. Modern reactive dyes were developed and refined in the 1950's. These took over from the natural dyes for a range...
