From time to time I get a call about something unique, Recreation Vehicles, Area Rugs, and Vintage Cars. I can only dye nylon and wool fibers, so if it’s anything other than that, it won’t take the dye.
I have been known to use Fiber Reactive dye for cellulose materials like cotton or viscose, it also works well on sisal, silk, wool, cotton, hemp, linen and some upholstery fabric.
