Polypropylene due to its non-polar nature has some limitations in certain special applications which are vulnerable by the surface properties of the fibers. Nowadays, research on surface modification of polypropylene (PP) textile fibers has also focused on improvement of their main drawbacks such as low moisture absorption and anti-static properties. This paper deals with novel low water using methods to modify the surface of polypropylene fibers by “ultraviolet radiation-hydrogen peroxide” and “microwave radiation”. Therefore, the samples were treated in different conditions and the surface properties were studied by measurement of moisture absorption, anti-static properties, tensile tests and FTIR-ATR spectroscopy. The results showed an increase in moisture absorption combined with improvement in anti-static properties, while the applied methods did not show any significant adverse effects on the tensile strength of the fibers. In addition, the analysis of the ATR spectra revealed some chemical changes and formation of functional groups such as carbonyl and vinyl groups on the surface of modified fibers. Overall, the results showed that the above methods can be applied for surface modification of PP fibers with considerable time and energy savings and low oxidant concentration which are textile industries priorities to minimize environmental pollution.
