**3. Results and Discussion**

A new method for developing high performance functional pile cotton fabric was designed. First, the functional performance of pile cotton fabrics was improved by incorporating a different percentage of lycra yarns with different densities according to the following parameters:


Second, SiO2 NPs were successfully synthesized and then applied on samples under study in a finishing bath containing an aqueous nano-SiO2 dispersion and EDTA.

Statistical Analysis

All the data of antibacterial activity and self-cleaning were analyzed using descriptive statistics based on mean and standard deviation.
