1,3,7-Trimetilksantin ile UV koruyucu fonksiyonel pamuklu kumaşların geliştirilmesi

This study was conducted to investigate the ability of 1,3,7-Trimethylxanthine as an ultraviolet (UV) absorber for the functionalization of cotton fabric. 1,3,7-Trimethylxanthine was applied at different concentrations via the pad-dry-cure method, and the structure of the functionalized cotton fabric was characterized by Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FT-IR), and UV–Visible (UV-Vis) Spectroscopy. The UV protection properties of the fabrics were measured in terms of UV blocking, and ultraviolet protection factor (UPF). The results were compared with those of fabrics coated using commonly used UV absorbers, TiO2, and ZnO. The fabric samples coated with 1,3,7-Trimethylxanthine at concentrations of 5% and 10% had low UV transmittance percentages in the UVB region. In particular, the protection rate of the sample treated with 1,3,7-Trimethylxanthine at a concentration of 10% was recorded as ultraviolet protection factor of 50+ (UPF 50+). The findings revealed that 1,3,7-Trimethylxanthine provided a non-toxic alternative to TiO2 and ZnO, and the fabrics functionalized with 1,3,7-Trimethylxanthine could have a potential application in the field of summer wear and outdoor activewear.
