call the people at rit dye and see if they make a dye just for synthetic fabrics. i haven't seen any on the market but that doesn't mean it doesn't exsist. good luck
In my experience, natural fabrics like silk and cotton, can dye well. Nylon, Rayon, Polyester etc. do not. Is there a specific dye for NYLON? I don't know - but just letting you know from my experiences so far.
