SYNTHESIS AND APPLICATION OF SILICA NANOPARTICLES ON POLYESTER BLENDED FABRIC TO IMPART SUPERHYDROPHOBICITY

摘要

In this study the P/C (67/33) and P/V (48/52) fabrics were treated with the silica nanoparticles and commercially available water repellent agent. The silica nanoparticles were synthesized by Stober method. The characterization of silica nanoparticles on the surface of both fabrics were done by using scanning electron microscope (SEM). The properties of P/C and P/V fabrics treated with the water repellent agent were compared with fabrics (P/C and P/V) finished with a combination of silica nanoparticles and water repellent agent. It was observed that the fabrics treated with water repellent agent showed the water repellency rating of 90 at 25gpl for P/C and for 15 gpl for P/V, while the rating of 90 was observed at 15 gpl of water repellent agent concentration when the P/C and P/V both fabrics were treated with the combination of silica nanoparticles and water repellent agent.
