I've not heard of a batik running that bad. Batiks should be dyed, boiled, washed, rinsed and the like quite a bit BEFORE they make to the public. Wax is used as a resist for the dye and that is how you get the wonderful patterns in the batik. Then the fabric should be washed in nearly boiling water to remove all the wax before they wind it on bolts and sell to the public.
You have a fabric that was not properly manufactured. You need to return that fabric to the store! Even if you don't get your money back, they should exchange it. They should then return their bolt to their supplier.
But, you can also use Epsom Salt to set dye in fabrics. It works great and much cheaper and readily available.
