- Abstract
- PET fabrics were photografted under continuous UV irradiation with 3-[(methacryloylamino)propyl]trimethylammonium chloride (MAPTA) and 4-benzoylbenzyltrimethyl ammonium chloride (BTC) as a cationic monomer and a photoiniotiator, respectively. It was found that the optimal grafting was obtained when PET fabrics were irradiated with a D-bulb in a UV energy of 35 J/cm2, on which were padded with an aqueous formulation of 3% photoinitiator concentration in advance. The surface of the grafted PET was characterized using FT-IR (ATR), ESCA, zeta potential measurement, water retention value (WRV). ATR and ESCA analysis, indicating significant alterations on chemical structure and atomic composition of increasing nitrogen content with increasing grafting yield. The zeta potentials changed from −4.9 mV for the untreated PET up to +16.7 mV for the grafted sample. The photografted fabrics showed an higher water absorbancy as indicated by the increased water retention value compared to the untreated PET. SEM images showed that PET surface was covered with the grafted cationic polymer.
