Abstract

The processing of textiles to achieve a particular handle is one of the most important aspects of finishing technology. Softeners and fatty acids improve soft handle, smoothness, elasticity, hydrophilic, antistatic and soil release properties on textiles. Fatty acid amide derivatives are commercial textile softeners used to improve softness of fibers surface.
In this research, cotton fabric was used as substrate and it was first scoured with nonionic detergent to remove any impurities. The fabric was then treated with anionic, nonionic and cationic fatty acid amide derivative softeners in water including 15 g/l at 30ºC for 30 minutes using ultrasonic energy during treatment. The treated fabrics were then dried/cured at 130ºC for 40 seconds. Some of the physical properties of the fabrics treated under ultrasound and those treated without ultrasonic energy, were compared and discussed.
As the results show, treatment of fabrics with softeners under ultrasound is more effective compared to conventional method.
