The morphology and structure of fiber precursors before and after acid leaching were characterized by scanning electron microscopy (SEM) and infrared spectroscopy (IR), and the Na+ leaching process was characterized by inductively coupled plasma spectrometry (ICP). The effects of hydrochloric acid concentration, leaching temperature and time on the leaching rate of Na+ and mechanical properties of the fiber precursor were investigated. The Na+ leaching rate reaches 85% after leaching in 3 mol/L hydrochloric acid solution for 12 h at 90℃. The maximum strength retention rate of the fiber after leaching can be obtained when the concentration of hydrochloric acid is 5 mol/L. In this case, Na+ ions in the fiber are replaced with H+ ions in hydrochloric acid during the acid leaching process, whereas hydroxyl group is further polymerized and dehydrated, thus strengthening the glass network during the heat treatment process and improving the fiber strength.
