In this study, the production and characterization studies of clay-chitosan based composites were investigated. The composite products were characterized by Scanning Electron Microscopy, Thermo Gravimetric Analysis, and Fourier Transform Infrared Spectroscopy. Besides antibacterial effect of the composites against S. Aureus and K. Pneumonia and dye adsorption properties were investigated. The effects of contact time, ionic strength, pH, and temperature on removal of remazol blue were investigated for the adsorption studies. The comparison was performed based on the characterization results of treated and untreated cottons. It was revealed that the one-step process of clay-chitosanbased fabrics gave significantly good properties to fabrics. These improved properties expressed the dyeing free-salt, antibacterial activity, and enhanced dyeability (dye adsorption capacity) of cotton. Consequently dyeability of the cottons was increased with the treatments. These treatments can be used in textile industry for the free salt dyeing which is a desirable property for the cotton in addition to the gained antibacterial activity. As a result, clay-chitosan composites can be considered as a hopeful composite for the multifunctional finishing textiles.
