Dyeing and diffusion properties of modified novel cellulose with triazine derivatives containing cationic and anionic groups

Cellulose is chemically modified with the compounds containing cationic and anionic groups. Dyeing and diffusion properties of modified cellulose are discussed. The exhaustion and fixation of reactive dyes on modified cellulose are higher than those on unmodified cellulose. Compared with unmodified cellulose, the dyed modified cellulose also gets good washing fastness. The diffusion coefficients of dyes at different temperature are calculated. Compared with unmodified cellulose, the diffusion of dyes in the modified cellulose shows significant change.
