Abstract
A key element in reducing human UV exposure is making proper UV protective goods with good ultraviolet protection factor (UPF) protection. The current research is focused on the synthesis of UV-protective functional dyes containing benzophenone-based UV absorbers and its application on wool and silk fabrics. Novel mono azo acid dyes were synthesized by the coupling of diazonium salt solutions of different aromatic amines with 4-hydroxybenzophenone, and these were applied on wool and silk. The fabrics dyed with the synthesized dyes showed less than 5% UVA and UVB transmission, indicating good protection against UV radiation. Dyed fabric also gave good to excellent washing, rubbing, and light fastness, and UV protection properties, even after ten washing cycles.
