Grafting of prepared chitosan-poly(propylene) imines dendrimer hybrid as a biopolymer onto cotton and its antimicrobial property

- Application of CS-PPI hybrid as a novel antimicrobial agent on the cotton fabrics.
- Optimization of grafting process using RSM technique.
- CS-PPI at a concentration of 20% (owf) demonstrated 100% bacterial growth inhibition.
- Weight gain of treated fabrics increased compared to the untreated fabrics.
- CS-PPI is a high potential antimicrobial agent for cotton fabric.
