In this research, the simultaneous cross-linking and antibacterial finishing of bleached cotton and cationized cotton by 3-chloro2-hydroxy propyl tri methyl ammonium chloride (Quat -188) with butane tetra carboxylic acid (BTCA) and nano TiO2 was explored. Butane tetra carboxylic acid can be linked to the cellulosic chains by ionic and covalent bonds. To do this, different concentrations of nano TiO2 and BTCA were examined to obtain the highest cross-linking and antibacterial effects Various characteristics of samples such as antibacterial against different microorganisms like two gram-positive bacteria (Bacillus cereus, Staphylococcus aureus), one gram-negative bacteria (Escherichia coli), and one fungus (Candida albicans), crease recovery angle, bending length, yellowness index, weight changes, water drop absorption time were investigated. The results showed that both the bleached cotton, and cationized cotton can be finished by the optimum concentration of nano TiO2 and BTCA for producing a cotton fabric with anti-wrinkle and antibacterial properties.
