Self-cleaning and stiffness characteristics of TiO2-cellulose coated cotton fabric

Popis výsledku v původním jazyce

In this report, a new method to make cotton fabric self-cleaning and permanently stiff by coating cellulose-TiO2on its surface is demonstrated. Nano TiO2 was dispersed in cellulose solution (cellulose in 60% H2SO4 solution) in order to coat it on cotton fabric. The surface morphology of cellulose-TiO2nanoparticles coated sample was analyzed by SEM. Characteristic peak of TiO2 in X-ray diffraction pattern at 24.2° and appearance of white particles on the surface of the cotton fabric in SEM micrographs confirmed the successful coating process. The Orange II dye was used as stain and its degradation was observed under UV light. X-ray diffraction analysis showed that cellulose II content increases slightly (by 5.3%) after the solvent treatment. Washing fastness study showed that the fabric stiffness was permanent and self-cleaning properties were stable up to 10 multiple washings. Air and water vapor permeability was not decreased considerably, whereas tensile strength was increased significantly after coating
