摘要

Reactive polyhedral oligomeric silsesquioxane containing multi-N-methylol (R-POSS) as crosslinking agent has potential application in improving physical properties of nano-cellulose materials. The effect of nano-crosslinking with R-POSS on color properties of dyed cellulose materials was investigated by K/S, CIE-LAB, and SEM. Physical properties and color fastness of nano-cellulose fabrics were discussed. The results show that the crease recovery angles of three color samples (yellow, red, and blue) cross-linked with R-POSS significantly increased. The elastic recovery property of crosslinked samples containing R-POSS got obvious improvement. K/S values of three color samples containing R-POSS decreased. Wet rubbing fastness, washing fastness, and perspiration fastness of three color samples containing POSS slightly increased. The cellulose fibers crosslinked with R-POSS imparted transparent and smooth surface.
