Modification of the Cotton Textile Surfaces by the Depositing of Thin Coatings Using the Sol-gel Method

In the present research the commercial cotton textile was modified by the sol-gel method to evaluate sol-gel technology suitability for cotton textile modification. The nanosol was deposited on the cotton textile by dipping process. The evaluation of the dipping process for thin zinc oxide coating deposition was made. The sol-gel method for nanosol preparation used in this research to implement zinc oxide coating on the fabric surface is a simple process that can be easily transferred to the textile industry, nanosol can be also applied by conventional coatings techniques used in the textile industry – the application can be implemented by simple dipping process. The zinc oxide coatings were deposited on the textile surface by sol-gel method without deterioration of textile intrinsic properties, such as flexibility, softness and etc. The analysis of the coated textile surface was carried out by scanning electron microscope (SEM) and energy dispersive X-ray (EDX) spectroscopy. Data received by SEM and EDX analyses evince that the deposited coatings are evenly distributed, not only on surface of yarns but in the depth of textile material as well and resistant to the exploitation impact (laundry test).

Cotton Textile Surface Investigation Before and After Deposition of the ZnO Coating by Sol-gel Method

In the present research the commercial type of cotton textiles were modified by the sol-gel method to evaluate sol-gel technology suitability for cotton textiles. The nanosol was deposited on the cotton textile by dipping process; as well evaluation of the dipping process for thin zinc oxide coating deposition was made. The analysis of the coated textile surface was carried out by Scanning Electron Microscope (SEM), Atomic Force Microscope (AFM) and energy dispersive X-ray (EDX) spectroscopy. Data received by SEM and EDX analyses evince that the deposited coatings are evenly distributed, not only on surface of yarns but in the depth of textile material as well and are resistant to the exploitation impact (laundry test). AFM analyse evince that the deposited zinc oxide coating constituted by spherical or ellipsoidal particles with 30-nm average diameter, assembled in larger clusters.

Dipping Time Influence on the UV Properties of Natural Textiles Treated via Sol-gel Method

In this study lightweight 100 % cotton fabric was successfully modified by the sol-gel method to impart high ultraviolet radiation (UVR) blocking property to the fabric surface. The cotton fabric was dipped in the nanosol solution for 1, 5 and 10 minutes, dried at 90 ºC for 10 minutes with thermal post-treatment at 120 ºC for 2 minutes. Comparison of coatings of samples prepared using different dipping time was made. The durability of the treatment was investigated by performing repeated home laundering. Excellent du-rability of the treatment was obtained, which indicates about good adhesion between the coating and the fabric surface. Before and after laundering tests ultraviolet protective properties of the textile samples were determined according to the standard, results of samples with dipping time 10 minutes show that textiles after treatment with nanosol have excellent ultraviolet protection properties, as well after launder-ing tests (50 washing-drying cycles) still provide excellent ultraviolet protection.
