Green chemicals and their applications to textiles became popular for imparting specific functional properties. Because of their complicated applications, the production of multifunctional textiles consumes high energy and produces high amount of wastewater. Therefore, in this study, an innovative one-step approach was used in order to obtain multifunctional cotton fabrics. Montmorillonite/Ionic Liquid (MMT-IL) nanocomposites were formed by using 3 different ionic liquids [IL1 (1-Methyl-3-butylimidazolium chloride, IL2 (1-Methyl-3- octylimidazolium tetrafluoroborate), and IL3 (1-Methyl-3-octylimidazolium bromide)], at 3 different concentrations determined which were based on the cation exchange capacity (CEC) of the montmorillonite clay mineral and MMT-IL nanocomposites. The synthesized MMT-IL nanocomposites were applied to the cotton fabrics by pad-dry-cure method. The pad-dry-cure process was carried out on fabrics also by using 2 different crosslinkers. Modified ethylene urea (MDEU) and (3-Chloropropyl)trimethoxylane (CPTES) were used as crosslinkers. Structural, thermal and surface properties of the MMT-IL nanocomposites and the treated fabrics were determined by FTIR, XRD, TGA, and SEM–EDS analyses. The performance properties of untreated and MMT-IL nanocomposite-modified fabrics were investigated. In order to determine multifunctional properties, antimicrobial, flame retardancy and conductivity values were examined according to the standards. In addition, whiteness index values were also measured to determine whether the MMT-IL nanocomposite modification affected the appearance properties of the fabrics. The performance properties of the fabrics were detailed by using the Box-Behnken experimental design. This paper describes the synthesis and application of Ionic Liquid-Clay Nanocomposites to cotton fabrics. The IL-MMT treated fabrics gained antimicrobial, flame retardant, and conductive properties.
