【 摘 要 】

In order to solve the composite interface problem caused by the hydrophobic groups of the natural fiber and hydrophobic property of the polymer, an ionic solution reaction to in-situ deposit calcium carbonate (CaCO3) particles was applied onto ramie fibers. The influence of reaction temperature, concentration of ions in solution, reaction time and dosage of dispersants EDTA - 2Na were studied. The surface morphology and structure of modified ramie fiber were characterized by scanning electron microscopy, infrared spectroscopy and tensile test. The results show that the optimal reaction time is 30min, and the extension of the reaction time has no effect on the test results. The optimization process of orthogonal test for the other three factors is as follows: the temperature is 40 degrees, the concentration of ion solution is 0.5mol/L, and the amount of dispersant EDTA-2Na is 4g/L.
