Influence of FFL-13 Oil on PSA Staple Fiber Properties

Abstract

With the aim of enabling the easy spinning of polysulfonamide (PSA) fibers, FFL-13 oil was successfully prepared. Specific resistance, the coefficient of friction, carding machine, electrostatic, cohesion, scanning tunneling microscopy (STM), and Fourier transform infrared (FTIR) spectroscopic analyses were conducted in this study. Results showed that increase in oil concentration, ambient temperature, and humidity induces decrease in PSA fiber-specific resistance and gradual increase in the antistatic property. Relatively high oil concentration and ambient humidity may cause fibers to become sticky and show increased roller winding. As oil concentration increased, fiber cohesion increased and fiber gliding properties showed an initial increase and subsequent decrease. The ideal oil concentration was determined to be 0.6%. This study proves that STM may effectively be used to determine the optimal oil concentration.
