•The effect of CS-PPI on the dyeability of nylon fabrics was studied.•Two reactive dyes were applied to investigate the dyeability of nylon fabrics.•The dyeing property of CS-PPI grafted nylon fabrics was increased.•Fastness properties of the dyed nylon fabrics have also been discussed.•The antimicrobial property of CS-PPI grafted nylon fabrics was improved.
Nylon fabric surface modification using chitosan-poly(propylene imine) dendreimer hybrid (CS-PPI) as a novel eco-friendly finishing agent has been reported. Effects of some operational parameters such as pH, temperature, time and CS-PPI concentration on grafting yield were examined through dye up-take using two commercial reactive dyes in terms of color strength (K/S). FTIR, SEM, and DSC data confirmed the grafting of CS-PPI onto nylon substrate. Optimal grafting values obtained were pH 4, temperature 60 °C, time 6 h and 2.5 g/L CS-PPI concentration. The performance of CS-PPI grafted nylon was investigated in terms of its dyeability, color fastness, and antimicrobial properties.
