A Study on the Light Stability Increasement of Non-Cellulosic Fiber

비섬유소 인조 섬유의 일광 안정도 증진에 관한 연구

Possible methods of protection of non cellulosic fibers, particularly nylon filament yarn, from the damaging effects of light are discussed. Manganese acetate, cupricacetate, G1-06-196 and sodium phosphate are used as a light stabilizer for nylon filament yarn. The light stability of filament containing different weight of TiO$_2$ is increased as the following order: Bright>Semi-Dull>Full-Dull The protection effect against light according to the present of the light stabilizer in filament increased in the following order: Manganese acetate> Cupric acid> G1-06-196> Sodium phosphate Manganese acetate is shown to be the most effecting salt for protecting nylon against light. 15 ppm of the salt is shown to be effective enough for protecting nylon filament yarn against light.
