Abstract

The effect of ALKALINE HYDROLYSIS with sodium hydroxide on NANO TITANIUM DIOXIDE (nano Ti02) adsorption was studied on POLYESTER fabric surface as well as the influence of nano Ti02 on the ALKALINE HYDROLYSIS of POLYESTER. To do this, the POLYESTER fabrics were treated with different concentrations of nano Ti02 and boiling sodium hydroxide solution for 1 h. The results revealed that ALKALINE HYDROLYSIS reduced the weight of the fabric, which was more prominent in presence of nano Ti02. Field emission scanning electronic microscope and energy dispersive X-ray confirmed the presence ofnano Ti02 on the POLYESTER fabric surface. Increasing sodium hydroxide and nano Tio2), concentrations led to higher loading ofnanoparticles on the POLYESTER fabric surface. Also, the PHOTOCATALYTIC ACTIVITY ofnano Ti01 particles on the POLYESTER fabric was confirmed by the degradation of methylene blue as a model stain under daylight irradiation. The results indicated that increasing sodium hydrox ide and nano Ti02 concentrations led to higher photocatalytic activities of the alkali-treated POLYESTER fabrics. Further, the bending rigidity of the treated POLYESTER fabrics decreased while the water absorption of the fabric improved. Unexpectedly, the TENSILE STRENGTH of the nano Ti01 treated POLYESTER fabrics improved even with the action of alkali and surface hydrolysis that usually produce fabric with lower TENSILE STRENGTH. The synergism influence of nano Ti02 particles in alkali hydrolysis of POLYESTER fabric indicated to lower weight fabrics. Overall, this treatment was considered as another useful property such as higher self-cleaning, hydrophilicity and TENSILE STRENGTH.
