The morphological structures of net-modified cotton cellulose with triazine derivative containing multireactive groups

摘要

Cotton fabric was chemically modified with a 1,3,5-triazine derivative containing multireactive and multicationic groups, 2,4,6-tri[(2-hydroxy-3-trimethylammonium)propyll-1,3,5-triazine chloride (Tri-HTAC). The morphological structures of net-modified cotton cellulose were investigated with differential scanning calorimetry, X-ray diffraction, and scanning electron microscopy. The results showed that crystallinity and preferred orientation of net-modified cellulose decreased. The tensile strength of net-modified cotton decreased and crease recovery angle increased. The thermal stability of the net-modified cotton was slightly improved. Representative scanning electron micrographs indicated that there appears to be appreciable difference in the appearance of the surfaces of the unmodified and the net-modified cotton fibers.
