One of the recommendations for future textile development is the modification of textiles to produce materials for human performance (sports, medical, and protective). In the current work, modifying a polyester surface with silver nanoparticles improved antioxidant and antibacterial protection. For this purpose, ethylenediamine aminolysis was utilized as ligands to fabricate polyester textiles, trapping silver ions to further reduce silver nanoparticles (AgNPs). Dopamine (PDA) was used to provide antibacterial and antioxidant properties to the polyester textile by converting silver ions into AgNPs through its phenolic hydroxyl groups. Pristine polyester, polyester treated with ethylenediamine, and PDA-coated AgNP-loaded polyester ethylenediamine were characterized using SEM, EDX, FTIR, TGA, and tensile strength. The antibacterial properties against and were examined through the broth test. PDA-AgNPs composite nanocoating exhibited improved tensile strength and antibacterial and antioxidant properties, demonstrating that polyester with a PDA-AgNPs overlay may be used for long-term biomedical textiles.
未来纺织品发展的建议之一是对纺织品进行改性，以生产用于人类性能（运动、医疗和防护）的材料。在当前工作中，用银纳米颗粒对聚酯表面进行改性可提高抗氧化和抗菌保护性能。为此，利用乙二胺氨解作为配体来制备聚酯纺织品，捕获银离子以进一步还原银纳米颗粒（AgNPs）。多巴胺（PDA）通过其酚羟基将银离子转化为AgNPs，从而为聚酯纺织品提供抗菌和抗氧化性能。使用扫描电子显微镜（SEM）、能量散射X射线光谱（EDX）、傅里叶变换红外光谱（FTIR）、热重分析（TGA）和拉伸强度对原始聚酯、经乙二胺处理的聚酯以及涂覆有PDA的负载AgNP的聚酯乙二胺进行了表征。通过肉汤试验检测了对[具体细菌名称1]和[具体细菌名称2]的抗菌性能。PDA-AgNPs复合纳米涂层表现出 improved tensile strength（此处原文有误，可能是“improved tensile strength”，意为提高的拉伸强度）以及抗菌和抗氧化性能，表明具有PDA-AgNPs覆盖层的聚酯可用于长期生物医学纺织品。
