How you colouring t-shirts, pants or enyone else? I heard about cooking ex. t-shirt with some pigment . maybye other kinds for colouring?
virtually all craft stores carry clothing dye. Make sure your item is natural fibers, those dye the best and most evenly. Just follow the instructions that come with these dyes, because it may vary from one product to the next.
the dye is the pigment. unless you are asking about plant dyes? I disagree with what C said, often the dye in the grocer's shop is for synthetic fibers. In North America, that would be RIT. the cooking you heard about is probably that same type of dye. It has to be used in hot water, and it's popular name is "hot water dye. (I'm thinking that Rit is a formulation of acide dyes. Cold water dyes are analine.)
most packs of dye of any kind will come with instructions on how to use. In case it doesn't, then the people who work in the craft stores often have experience and info they're willing to pass on, so give them a try. Wasn't thinking about RIT. I don't find that brand often where I am, so I really hadn't used it much. But I have found other clothing dyes at craft stores (different brands depending on what colours I wanted) and they always worked better on natural fibers vs synthetic. But I will stand corrected. Krzysiek, my best suggestion to you is to go out and check out dyes available where you are and look at instructions that come with it, and take it from there. Staff at these stores can recommend best name brands - I'm sure Poland has different brands available than what we have in N. America.
C, unless it is analine dye (cold water) , and I do see some off names in that, usually with soda ash fixer packets, the dyes that most posrters here find are the RIT company. I've long forgotten the "don't buy list, and I should change that.
I'm not disagreeing with you. I have used both warm/hot water dyes and cold water dyes, and on all sorts of different materials. In my experience (and I may be the only one) irrigardless of brand or whatnot, for me the dyes work best on natural fibers. If others manage to find dyes that work on anything, than kudos to you. Also, krzysiek I think is from Poland, so he may not have access to the same brands of dyes that we have here. I was just offering a suggestion or idea to what to look for, where and how.
good shop, thanks. I will think about it. These soda ashes are so productive and not too expensive. good value.
if what you are after is a solid color, you will get less streaking if you wet the garment thoroughly before immersing it in the dye.
