| Abstract | In this research, chitosan-poly(propylene)imine dendrimer hybrid (CS-PPI) was applied to wool fabrics; and weight gain and antibacterial properties of the grafted wool fabric by CS-PPI were investigated. A response surface methodology employed for optimization of the important factors such as pH, processing time, and CS-PPI and cross-linking agent (CA) concentrations. The physical properties showed sensible changes regardless of weight gain. The maximum weight gain was obtained when the wool fabrics were treated with pH 5, processing time 24 h, CS-PPI 20 %(owf) and CA 5 % over weight of fiber (owf). Scanning electron microscopy analysis showed the presence of foreign particles determinedly fixed to the surface of the wool fabric. Fourier transform infrared spectroscopy and differential scanning colorimetry revealed the grafting of CS-PPI onto wool fabric by forming novel chemical bonds between the wool and CS-PPI molecules. The treated wool fabrics showed broad-spectrum antimicrobial activity against gram-positive and gram-negative bacteria. Antimicrobial activities of the treated wool by CS-PPI at a concentration of 20 % over weight of fiber (owf) demonstrated 100 % bacterial growth inhibition, which was preserved more than 84 % even after being washed in 12 various conditions repeatedly. The grafted wool fabrics have antibacterial potential due to the antibacterial property of CS-PPI molecules. The mechanism of CS-PPI grafting onto wool fabric using CA was proposed. The findings of this study support the potential production of the new environmentally friendly textile fibers. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
