Synthesis and Application of New Benzotriazole Derivatives as UV Absorbers for Polyester Fabrics

Abstract:

Article Preview

2-(2′-Hydroxyphenyl)-5-amino-2H-benzotriazole was synthesized and subjected to acylamidation to yield three new ultraviolet (UV) absorbers. The largest absorption wavelength and the relationship between the concentration and the maximum absorbance of the UV absorbers were measured in dimethylsulfoxide. Then the four benzotriazole type UV absorbers were dispersed and applied onto polyester fabrics with the high temperature and pressure dyeing method. The stabilizing effect against UV light of the finished fabrics was studied by ultraviolet protection factor (UPF) and UV transmittance measurement.
