Anyone had luck dying polypropylene material?

I know that machine made oriental rug manufacturers use poly in almost all their rugs, which are all dyed. Might try a little research on how they are manufactured. You might find out about the dying process. I will do a little searching myself.

I did a test last night on some poly paint booties with dismal results.

I'm not an expert in this, but I can relate it to another field--I make my living in the theatre. Years ago I used to build a few prosthetics and wigs. I discovered I couldn't dye the synthetics very easily because, unlike human or animal hair or fur, it has no real texture...no pores, no interior, nothing to hold onto the dye.
It would slide right off.
I did not pursue this any further at the time. There were alternatives.
But it appears to me that synthetics are created with the color as an integral part of the chemistry. Take apart a plastic toy...it's the same color inside as outside.
Attempting to add color might be a useless pursuit.

I discovered the same thing today. I talked with someone who told me that polypropylene is dyed in its liquid form before being extruded. I have officially thrown in the towel in pursuit of another material.
