고 일광견뢰도 Solvent 염료의 폴리에스터 염색에 관한 연구

Abstract

This research aimed at scrutinizing the dyeability of some solvent dyes on polyester and their light fastness to be exploited as a breakthrough in light fastness where utmost fastness is required such as ultramicrofibers and industrial markets. Dyeability on polyester was mainly evaluated by HT exhaust dyeing according to the general procedure. Light fastness has been tested by a preliminary UV test followed by HT xenon test in compliance with standard SAE J1885, 224 KJ. Fading has been determined quantitatively by evaluating the shade deviation and the strength difference between unexposed and exposed samples by means of CIELab values.
