NOVELTY - Preparing graphene composite polyacrylic acid superabsorbent fiber involves weighing each raw material in proportion. The raw material comprises polyacrylic acid, polyacrylamide, polyvinyl alcohol, glutaraldehyde, potassium peroxodisulfate, modified graphene, acetone and polymethyl methacrylate. The spinning stock solution is prepared, poured spinning stock solution into spinning equipment, so that spinning stock solution is ejected from spinneret and enters coagulation bath to form filaments. One end of filament is taken out and wrapped on drum, and made spinning on drum by drawing for winding, and dried silk on drum. USE - Method for preparing graphene composite polyacrylic acid superabsorbent fiber. ADVANTAGE - The method enables to enhance tensile breaking strength, and improves processability under premise of maintaining water absorption and water retention of polyacrylic acid fiber.
