Abstract
To enhance the easy care finishing properties of cotton fabric along with maintaining its mechanical properties, a new route based on ionic crosslinking was employed. In this research work, pre-cationized cotton fabric was crosslinked using ammonium citrate in presence of sodium hypophosphite at 180°C for 90s. The effect of cationization level and ammonium citrate as well as silicon micro-emulsion softener concentrations on the performance properties of cotton fabric was determined. Results obtained show that the pre-cationization of cotton fabric having 0.09% nitrogen followed by crosslinking with 6% ammonium citrate brings about an enhancement in both dry and wet recovery angles along with a slight improvement in TS. Furthermore, the pre-cationized sample having the nitrogen content of 0.09% was characterized before and after ester crosslinking with 6% ammonium citrate (compared with an untreated sample) using thermo gravimetric analysis and Scanning Electron Microscope.
