My school science fair is coming up in a couple weeks, and i need to get going on my project.
I think this is my question: How does the concentration of dyes affect their colorfastness?
but i need to know what to do... I think I'm going to dye a fabric with a natural dye (maybe blueberries or something?) and then let it set, wash it a few times, and see how it fades.
I'll do that with different amounts of dye each time, so i can test the concentration and how it affects the fading. but is there any special way that i can measure the degree of fading on the fabric? any other ideas? thanks, your help is much appriciated!

use store-bought dye. easier and you will get consistent quality. this is not an experient to make your own dyes. that eliminates several variables. to evaluate fading have a control sample of each dye concentration that you used. compare washed sample to original swatch after each wash cycle. be sure to use the same kind of fabric for every test as fabric type is another variable. run multiple tests of each concentration (3). add another dimension and record not only how much the dye fades, but how many washes it takes to fade. you should also be able to determine the minimum amount of dye needed to achieve best results. in otherwords, show how this research relates to the real world. dye costs money, so the fabric makers would need to know the least amount that gives the best effect.
most of all - HAVE FUN!

dip it into soda ash first then dye it
