Thanks for your question Sheena. I can't answer your question about which materials absorbs dyes the best because there are different types of dyes that attach themselves the surfaces in different ways. The different types of dyes have been developed so you can pick the dye you need based on the material you need to dye. Before modern science, dyes were found through trial and error. Now we know that if we want to color a hydrophobic material (many synthetic polymers, for example) you need to use a hydrophobic dye. So, you really need to have a specific material in mind before you can choose a dye. I found several web sites that may help you with some more information. http://www.dyesonline.com/intro.htm http://www.csdl.tamu.edu/FLORA/328Fall98/fiberdye.html http://www.life.uiuc.edu/plantbio/263/DYES.html http://www.aatcc.org/magazine/may1997/p29-35/p29-35.html
