Abstract

This manuscript aimed to improve the ignition, mechanical properties and antibacterial activity of polyester fabric irradiated with UV/Ozone (for 30 minutes) after coated with sol-solution and pomegranate rind natural dye (PRND). Phenyltrimethoxysilane (PTMS) was used to form siloxane bonds as the main chain of the sol coating. The effect of (PRND) concentration was studied. The Fourier transform infrared (FTIR), illustrated the inter-chemical reaction between (-OH) groups in sol-solution with the free radical on the irradiated polyester fabric. Adding different amounts of PRND during solsolution synthesis, lead to increase reduction percent of gram-negative (E. coli) and gram-positive (S. aureus) bacteria and improve the thermal and mechanical properties with no flame retardancy effect. The flame chamber (UL/94), limiting oxygen index (LOI), and EN ISO 11925 tests were used to investigate the ignition properties of the treated and untreated specimens.

溶胶-凝胶涂层和石榴皮涂层聚酯织物的阻燃性，力学性能和抗菌活性

抽象的

该手稿旨在改善涂有溶胶溶液和石榴皮自然染料（PRND）的UV /臭氧（30分钟）辐照后的聚酯织物的着火性，机械性能和抗菌活性。苯基三甲氧基硅烷（PTMS）用于形成硅氧烷键，作为溶胶涂层的主链。研究了（PRND）浓度的影响。傅立叶变换红外光谱（FTIR）说明了溶胶溶液中（-OH）基团与被辐照的聚酯织物上的自由基之间的化学反应。在固溶体合成过程中添加不同量的PRND，导致革兰氏阴性菌（E. coli）和革兰氏阳性菌（金黄色葡萄球菌）的减少百分比增加）细菌并改善热和机械性能，而没有阻燃效果。火焰室（UL / 94），极限氧指数（LOI）和EN ISO 11925测试用于研究已处理和未处理样品的着火性能。
