Which of the following will be the most difficult to dye: wool, cotton, orlon, dacro, and polypropylene? Which will absorb the dyes in a similar way?
Chromatography… -_- are you kidding me? If you don’t know the answer don’t pull crap out of your @ss.

Depends on the dyes you’re trying to use, and whether it’s a modified fiber or not. Of this bunch, I’d say polypropylene, which is usually mass dyed, but there’s now a version dyeable with disperse dyes.http://www.textileworld.com/Articles/2006/Septembe… — I just haven’t seen any.
For more clues on what will dye with what sorts of dyes, look at the chemical structures. Hint: nylon has a very similar bond to one of the natural fibers that dyes easily.

it would be better if you’ll do a chromatography test
