Modification of cotton fabric via amine-terminated dendritic group to improve the ink-jet printing properties

The cotton fabrics were modified with amine-terminated dendritic hyperbranched polymer (ATDH) to enhance colorstrength in ink-jet printing method. The bonding between cotton fabric and amine-terminated dendritic polymer were characterized by FTIR. Different concentrations of amine-terminated dendritic polymers were applied on the cotton fabrics. It was found that the amine-terminated dendritic polymers improve the color strength of fabric. It was also found that cotton fabrics modified with the 2wt% ATDH have the best color strength value. The effect of the acid treatment on the color strength value of cotton fabrics modified with the 2wt% ADP was also investigated. The result showed that the presence of acid decreases the K/S value of fabric modified with 2wt% ADP whereas its value is higher than the unmodified fabric
