Abstract
The wastes of various untreated and uncolored textile materials resulting from research and service activities such as cotton, wool, and polyester fabrics in the Textile Research and Technology Institute were given added value by treating them with synthesis silver nanoparticles and chitosan in the present or absence of extracted natural oils from plants like basil, lemon (Citrus aurantifolia) and mint. Using the method of immersion, squeezing, and thermal stabilization in certain conditions selected from time and temperature to improve its antimicrobial activity. Transmission Electron Microscopes (TEM) were used for the determination of the size, shape, and size distribution of Synthesis of silver nanoparticles (AgNPs) using different oils. The treated fabrics morphological changes were characterized using (SEM) and energy-dispersive X-ray analysis. The color intensity and the ultraviolet protection (UPF) of the printing-treated fabrics in comparison to the untreated ones were investigated. Thermogravimetric Analysis (TGA) is performed to investigate the changes in the polymeric structure of fabrics. The changes in tensile strength and elongation at break have been studied. The results of this investigation displayed significant improvement of treated fabrics against the antimicrobial Staphylococcus aureus (G+) (S. aureus) and Escherichia coli (G+) compared to the untreated ones.
