Abstract

　We have investigated the effects of surface treatment conditions and the fabric structure on the surface hydrophobicity of the different cotton fabrics. Hydrophobic surface of the cotton fabrics were prepared by treating the cyanuric chloride-immobilized cotton fabric with alkylamine in benzene. As a result, we obtained the following findings. 1) The changed processing conditions for each step in the process suggested that the water repellency can be adjusted by concentration of reagents and treatment time. 2) Water repellency were decreased with decrease in the number of carbon atoms of alkylamine. 3) The fabric structure of cotton fabric used in this study affected the surface hydrophobicity of the alkylamine treated cotton fabric. 4) Water repellency of the cotton fabrics obtained by treatments in this process was found to be almost same as that the fabric sample treated with the ready-made water repellent.
