We developed a novel organic polymer using zwitterion from 1-(3-aminopropyl)imidazole and 1,3-propane sultone to fabricate NPs. Zwitterion was added to polyacrylic acid-grafted oleylamine (PAA-g-OA) by COOH activation and amidation to produce PAA-g-OA (zwitterion). Thereafter, the NPs were prepared using microemulsion methods and distributed in the polyurethane (PU) fibers via a wet-spinning process. The stretchable fiber structure of PU@PAA-g-OA (zwitterion) was demonstrated by the high elongation at break (600%). Also, the hydrophobic surface properties of fibers were modified to hydrophilic ones. These results suggest a novel approach that uses functional polymer nanoparticles to alter surface chemistry and enhance mechanical characteristics in textile applications.
