Environmentally friendly Finishing of Cotton Fabric via Star-like Silver micro/nano Particles Synthesized with Neem/Salep

In this study, a novel silver solution was prepared by a simple green synthesis method using AgNO3, neem and salep extracts at room temperature. The results of UV-Visible spectrophotometer and Scanning Electron Microscopy (SEM) showed the formation of silver particles with a star-like morphology and sharp edges in the solution. In order to achieve an antibacterial cotton fabric, it was treated with the solution containing star-shaped silver particles by an impregnation method. Also, in order to change the surface charge of cotton fabric and more silver adsorption, a cationic surface modification was performed. Surface morphology and antibacterial properties of treated cotton fabric were characterized by SEM, inductively coupled plasma-optical emission spectrometer (ICP-OES), and antibacterial test based on the AATCC100 method, respectively. SEM images showed the presence of silver particles on the surface of treated fabric samples and ICP-OES determined the amount of silver content on the fabrics. In addition, the bacterial inhibition experiments demonstrated that the treated cotton fabrics with the star-like Ag particles synthesized by neem and salep have significant antibacterial properties against gram-positive and gram-negative bacteria. The utilized method was an easy, nontoxic, and environmentally friendly procedure for the preparation of antibacterial textiles with attractive feature in the medical and hygienic products

Antibacterial PET-Silk fabric containing Salvia officinalis extract

In this study, novel PET-Silk fabric is introduced via finishing PET fabric with silk hydrogel and Salvia officinalis extract. The silk hydrogel was prepared from waste silk; morphology and chemical structure were evaluated by scanning electron microscopy, X-ray diffraction, and Fourier transform infrared spectroscopy methods. The results indicated the 3D porous network and crystalline structure of hydrogel. The polyester fabric was finished with prepared hydrogel. Contact angle and water uptake of modified fabric were assessed. S. officinalis extract was used as an antibacterial agent. Results of antibacterial tests confirmed a remarkable antibacterial effect of finished fabrics with the extract
