It is used to resist insects and mold and be mothproof with special odor. In other words, the odor is thought to be unpleasant enough to drive animals away in repellent products. It is possible to have creation of environmental pollution and endanger human health. This research reveals refined naphthalene made with various colors, better appearance and greater performance in order to satisfy the requirements for textile market and various applications. This research analyses refined naphthalene between C-company product and N-company product. The analysis results showed product with different components on the table.Let the refined naphthalene with dyed of eight dyes and flavored of three essences be used. The experiment of color fastness with light test is to determine how much the color will fade when exposed to a known ultraviolet light source. In this paper, the experiment data from GC/MS spectrum described kinds of structure on color mothballs after 80 hours phototherapy treatment as shown figure.Keywords:naphthalene, quinoline, color, fade, whiteness
