Abstract

The improvement of the fabric properties considers the most important reasons for textile functionalization.The present study focuses onone finishing bath for imparting durable multifunctional properties such aswet crease recovery angle, antibacterial andultraviolet (UV) protection to wool fabrics. Polyurethane (PU) and zinc oxide (ZnO) mixture finishing bath were selected to treat wool fabric at the different concentrations of the finishing agents as well as the curing temperatures and curing times were studied.  The results revealed that the finished wool fabric have a high bacterial reduction percent against two tested bacteria Gram negative bacteria (Escherichia coli ) and Gram positive bacteria (Staphylococcus aureus) in addition to enhance the wet crease recovery even after twenty washing cycles.The surface of treated wool fabrics was characterized byScanning Electron Microscope (SEM) and Electron Dispersion Emission X-ray (EDX).Also the effectof the treatment on physico-mechanical propertieswas evaluated. The treated wool fabrics gave an excellent protection against the UV radiation. The stiffness, the resistance to tear, air permeability and wettabilityincreased after the treatment of wool fabrics with PU/ZnO and there isn’t a significant change in the tensile strength. Effect of PU,ZnO and their mixture on the dyeing properties of wool fabric was studied as well as the colorfastness of dyed fabrics.
