Synthesis and application of the cationic modifier on the ramie fiber

Song Xinrong, Liu Fang, Jin Yulin

A new cationic modifier was synthesized using trialkylamine and epoxy chloropropane, it was used to modify surfaceÂ’s morphologies of the ramie fiber. The modified ramie fiber was characterized by FT-IR spectroscopy and scanning electron microscope (SEM). Then modified ramie fiber was dyed with reactive dye and dye behaviour of the modified ramie fiber was measured. Results shown that the dye uptake of the modified ramie fiber can be controlled by changing the cationic modifier content. K/S value, the colour fastness and the dye uptake of the modified ramie fiber were greatly improved.
