Mass coloration of nylon using a melting-reactive dye is described. 1,4-Dihydroxyanthraquinone diglycidyl ether was synthesized as a novel melting-reactive dye in which the epoxy groups in the dye would react with amino groups of nylon by a nucleophilic addition mechanism. The dye was confirmed by UV-vis, IR and 1 H NMR spectroscopic analyses. The effect of the proportion of the added dye...
Mass coloration of poly(ethyleneterephthalate) (PET) by using a melt-reacting dye is described, and affords an economical favorable and environmentally friendly method of coloration. Perylene-3,4,9,10-tetracarboxylic acid dianhydride (PTAD) was used as a melting-reactive dye in poly(ethyleneterephthalate) and showed high thermal stability. A chain-extending reaction was confirmed by UV-vis and IR...
