碩士 === 國立臺灣科技大學 === 纖維及高分子工程系 === 90 === Bis (triazinyl) aminostilbene derivatives of fluorescent whitening agents (FWAs) had been synthesized which was in order to research their anti-acid properties. The condensation was prepared by Cyanuric Chloride(CC) and the amino groups in pH=1~3. After that, condensing 4,4’-Diamino stilbene-2,2’-disulpHonic acid (DAS) and the other organic functions. These compounds were aimed at fluorescent absorption and luminescence. The products were used by cellulose padding between pH3 and pH6. As the result of ACS measurement, their CIE Lab data proved the fluorescent brightening agents were satisfactory at cotton fabrics and gave excellent results in acid spotting fastness and wash fastness.
