<table>SEM images of INI-treated fibers. (a) 100°C (Na<sub>2</sub>CO<sub>3</sub> : CaCl<sub>2</sub> = 1 : 1, mol : mol), (b) 100°C (Na<sub>2</sub>CO<sub>3</sub> : CaCl<sub>2</sub> = 1 : 2, mol : mol), (c) 130°C (Na<sub>2</sub>CO<sub>3</sub> : CaCl<sub>2</sub> = 1 : 1, mol : mol), (d) 130°C (Na<sub>2</sub>CO<sub>3</sub> : CaCl<sub>2</sub> = 1 : 2, mol : mol) at 1 : 2, (e) 160°C (Na<sub>2</sub>CO<sub>3</sub> : CaCl<sub>2</sub> = 1 : 1, mol : mol), and (f) 160°C (Na<sub>2</sub>CO<sub>3</sub> : CaCl<sub>2</sub> = 1 : 2, mol : mol). The white arrows designated the CaCO<sub>3</sub> particles.</table>
