Chemical and morphological structures of modified novel cellulose with triazine derivatives containing cationic and anionic groups

Cellulose fabric was chemically modified with the compounds containing cationic and anionic groups. The molecular chains of modified cellulose had both cationic and anionic groups. The chemical and morphological structures of modified cellulose were investigated with X-ray diffraction, FTIR spectra, differential scanning calorimetry (DSC), scanning electron microscopy (SEM) and nitrogen content analysis. The crystallinity and preferred orientation of novel cellulose decreased. The thermal stability of the modified cellulose was slightly improved. Representative scanning electron micrographs indicated there appears to be appreciable difference in the appearance of the surfaces of the unmodified and the modified cellulose fibers.
