Abstract


Chapter1:This chapter is about a brief overview of quality,function and various types of application about Leuco dyes,especially molecular formula and status of ck-37;this chapter always introduces the research by using ultraviolet-visiblespectro-photometer;finally,introduces-the-composition,prop erties,classification and application of glass fiber and basalt fiber.Chapter2:Study the nature of spectrum of ck-37and Acid reaction by using Absorption Method of UV-visible molecular. Studied the absorbance of ck-37through the3kinds of color acid. Among them, every kind of acid has studied its concentration, temperature, time and molar ratio and concluded that color acid with good color effect for ck-37. Among them, Hydrochloric acid, oxalic acid and phthalic acid have good effects for ck-37. The color effect is enhanced with increasing acid concentration. Color effect is out of time control. The best color temperature is normal atmospheric temperature. Chapter3:This chapter studied the influence of the effect of metal ion for ck-37. Investigated the absorbance of ions’(Fe3+,Al3+,Sn2+and Sn4+) reaction with ck-37.And also knows that they can make ck-37effective color, and has bright color and better effects. Though the different metal ion concentration, temperature and time and different molar ratios of metal ions and ck-37,we can conclude that ck-37color effect is enhanced with the increasing concentration of metal ions,and color effect is substantially independent of time and temperature. The complex ratios of Fe3+,Al3+,Sn2+and Sn4+and ck-37are2:3,1:1,1:land1:3.Chapter4:This chapter mainly introduces the interference effect by surface active agent to the coloration of ck-37.Through the changes in different conditions we can learned that,non-ionic surface active agent had no effect to ck-37;cationic surface active agent had enhancement of coloration of ck-37;and with a small amount of anion surface active agent the coloration of ck-37were strengthened,but too much additions would make the coloration of ck-37weaken or even no color.Chapter5:This chapter mainly include the colorant formulations about glass fiber and basalt fiber,and the simple trust test about the coloring of the fibers.The experimental results obtained that the colorant formulations According to the mass fraction is:ck-370.2-0.4, ortho-hydroxybenzoic acid10.3-12.6, absolute ethyl alcohol and acetone83-89,surface active agent0.15-0.25, bisphenol A1.2-1.3, flavouring agent0.05-0.15.According to the reliability of the test results,the colored fibers has a strong water resistance and oxidation resistance,so does the acid resistance.The colored fibers has a little alkali resistance.And some reducing substances can make the colored fiber fade,these reducing substances can be used as the fade material.
