This paper reports a novel route for the coloration of polyester fabric with green synthesized silver nanoparticles (G-AgNPs@PET) using chitosan as a natural eco-friendly reductant. The formation of AgNPs was confirmed by UV-visible spectroscopy. The morphologies and average particles size of G-AgNPs was investigated by transmission electron microscope (TEM) analysis. The uniform deposition of G-AgNPs on the PET fabric surface was confirmed with scanning electron microscopy (SEM) and Fourier transform infrared (FT-IR) spectroscopy. The thermal properties were investigated using a thermogravimetric analyzer (TGA). The coloration and fastness properties of fabric were found to be significantly improved, a result related to the surface plasmon resonance of G-AgNPs. The antibacterial properties of fabric were also found to be excellent as more than 80% bacterial reduction was noticed even after 10 washing cycles. Overall, the proposed coating process using green nanoparticles can contribute to low-cost production of sustainable textiles.

本文报道了一种使用壳聚糖作为天然环保还原剂，以绿色合成的银纳米颗粒（G-AgNPs@PET）对聚酯织物进行染色的新方法。通过紫外可见光谱确认了银纳米颗粒的形成。通过透射电子显微镜（TEM）分析研究了G-AgNPs的形态和平均粒径。用扫描电子显微镜（SEM）和傅里叶变换红外（FT-IR）光谱确认了G-AgNPs在PET织物表面的均匀沉积。使用热重分析仪（TGA）研究了热性能。发现织物的染色和色牢度性能得到显著改善，这一结果与G-AgNPs的表面等离子体共振有关。还发现织物的抗菌性能优异，即使经过10次洗涤循环后，细菌减少率仍超过80%。总体而言，所提出的使用绿色纳米颗粒的涂层工艺有助于低成本生产可持续纺织品。
