A Novel Method for Preparation of Antimicrobial Cellulose Textile by Surface Carbamatization and N-Chlorination

Abstract:

Surface carbamatization of cellulose fabric was accomplished through co-heating with urea. The carbamate group on textile surface was transformed to N-chlorocarbamate after exposure to sodium hypochlorite solution. Effect of carbamatization temperature, time on Nitrogen content of fabrics was investigated, and the effect of bleach technology on chlorine content on fabrics was also studied. Using shake flask method antimicrobial activities against E. coli and S. aureus were studied. The results showed that when carbamatization temperature was 138°C and the time was 3 hours, nitrogen content of cellulose fabric was the highest: 1.47%. Antibacterial ability of cellulose fabrics with 0.81mg/g chlorine against E. coli and S. aureus was 99.9999% and 100%, respectively.
