Simultaneous Dyeing and Ultraviolet Protection of Wool Fabric with Pomegranate Rind Using TiO₂ Nanoparticles

ABSTRACT

The effect of TiO₂ nanoparticles on the dyeing of wool fabric with pomegranate rind was investigated. The TiO₂ nanoparticles were prepared by the solgel method. Various concentrations of the nanoparticles were added during the dyeing of wool with pomegranate. The dyed fabrics were analyzed for physico-mechanical properties, color values, and Ultraviolet Protection Factor (UPF). The presence of nanoparticles on the fiber surface was confirmed by SEM, EDX, and FTIR analysis. The phytochemical analysis of aqueous pomegranate rind showed the presence of saponins, phenols, tannins, glycoside, flavonoids, and terpenoids. The particle size analysis results inferred that the solgel synthesis produced TiO₂ nanoparticles of around 200 nm size. After dyeing, the color intensity and UPF of the dyed fabric increased along with the concentration of TiO₂ nanoparticles. The dyeing process did not cause any significant reduction in the strength properties of the wool fabric. The rubbing and washing fastness properties of the dyed fabric were found to be good.

摘要

研究了纳米TiO2对石榴皮羊毛织物染色的影响. 采用溶胶-凝胶法制备了TiO2纳米颗粒. 在用石榴染色羊毛的过程中‚添加了不同浓度的纳米颗粒. 对染色织物的物理机械性能、颜色值和紫外线保护系数(UPF)进行了分析. 通过SEM、EDX和FTIR分析证实了纤维表面存在纳米颗粒. 对水石榴皮进行的植物化学分析表明‚其中含有皂甙、酚类和单宁、糖苷、黄酮和萜类化合物. 粒径分析结果推断‚溶胶-凝胶合成产生了约200 nm大小的TiO2纳米颗粒. 染色后‚染色织物的颜色强度和UPF随着TiO2纳米颗粒浓度的增加而增加. 染色过程没有导致羊毛织物的强度性能显著降低. 染色织物的摩擦牢度和洗涤牢度良好.
