Message: Hello. I am doing a school project and need to research how dyes temperature affects how well it works on cotton poplin and i was wondering if you could help. Thank you if you can reply

I can't help you without knowing what kind of dye you are talking about. The mechanism of direct dye on cotton is very different than that of fiber reactive dye, which is why the latter is so much more satisfactory in general. The means by which heat affects the dyeing process is extremely different for these two types of cotton dye.

Also see my FAQ, "What is the effect of temperature on fiber reactive dyes?".
