Abstract: 
The processing of textiles to achieve a particular handle is one of the most important aspects of finishing technology. Softeners are one of the main compounds in finishing process and can improve some properties of textiles, depending on the chemical nature, including soft handle, smoothness, elasticity, hydrophilic, antistatic and soil release properties. They are classified according to their ionic character and the main classes are: anionic, cationic, nonionic, amphoteric, reactive and silicone. Macro- and microemulsion silicone softeners are commercial classes of softeners but nanoemulsions are new class of softeners in textile industry. The purpose of this research was to study the effect of micro and nano silicone softeners on different properties of polyester fiber. Polyester fabrics were first scoured with nonionic detergent and were then treated with three concentrations (10, 20 and 30 g/L) of micro- and nanoemulsions of silicones. The drapeability of treated samples with 10 g/lit of solution was decreased and more decrease was observed with increase in silicone concentration. Colorimetric properties of softener treated fabrics were evaluated with a reflectance spectrophotometer. Nanoemulsion silicones changed a little the surface reflectance of fibers compared to micro silicone softener. Increase in weight of all samples was observed which shows the coating of silicones on fiber surface. Nanoemulsion silicones showed better results on samples treated compared to mirco emulsion silicones.
