In this research pure cotton textile have been modified by the sol-gel method to implement zinc oxide coating on the fabric surface. Scanning electron microscopy (SEM) has been used to examine the nature of the surface modification after application of coating by sol-gel method. For preparation of thin-coatings by the sol-gel method the textile samples need subject to thermal after-treatment, thermal after-treatment temperature have very important influence on the received coating and textile, therefore in present research different curing temperatures was used for preparing samples, and was evaluated it influence on samples.
