Effect of Nano and Micro Emulsion Silicone Softeners on Properties of Polyester Fibers

Abstract The processing of textiles to achieve a particular handle is one of the most important aspects of finishing technology. Softeners improve soft handle, smoothness, elasticity, hydrophilic, antistatic and soil release properties on textiles. Macro and micro sized silicone softeners are commonly used for these purposes but nano silicone is a new class of softener. In this research, polyester fabrics were first scoured with nonionic detergent and then treated with three concentrations of nano and micro silicone softeners in water including 10, 20 and 30 g/L at 30°C for 60 seconds by padding method. The treated fabrics were then dried/cured at 130°C for 40 seconds. The pH was maintained at 5 using acetic acid. Some of the physical and chemical properties of the treated fabric samples were discussed. The drapeability of nano emulsion treated samples was decreased compared with micro emulsion treated ones. Colorimetric properties of softener treated fabrics were evaluated with reflectance spectrophotometer. Scanning electron microscope photographs showed nano silicone particles aggregated on fiber surface. Moisture regain of nano emulsion treated samples was decreased compared with micro emulsion treated due to coating of nano silicone particles.
