In this paper, treated Saudi cotton fabrics were prepared by dipping them in chitosan and chitosan/ZnO-NPs solutions offour different concentrations (10, 20, 30, and 40 wt% ZnO-NPs). The chemical compositions, optical properties, mechanicalcharacteristics, and air permeability of the prepared fabrics after immersion were investigated. The tristimulus valuesof the CIE, color parameters, extinction coefficient, and color strength were evaluated using reflectance spectra recorded inthe visible region. Untreated fabric and treated cotton fabrics (CF/Ch/ZnO-NPs) were assessed with regard to washability,acidic perspiration, and alkaline perspiration. Differences in the ratio of distinct bands can be seen in the FTIR spectroscopydata, indicating that the intensity of the O–H band is decreasing. Differences in the ratio of the distinct bands can be seen inthe FTIR spectroscopy data, indicating that the O–H band’s intensity is decreasing. The photon energy dependence of theabsorption coefficient revealed that optical transmission is allowed and direct. The ultraviolet protection factor (UPF) wasdetermined using color strength analysis, and the results showed that the treated cotton fabrics provide good-to-very goodUV protection. The fabrics were also very durable when it came to multiple washes. The mechanical characteristics and airpermeability data show a relationship between the presence of chitosan and the quantities of ZnO-NPs, as well as interactionsbetween them and the fabric network. This is the first study to try and improve the characteristics of Saudi cotton fabrics, sothat they can be used in a variety of industrial and medicinal applications.
