[0003] That is, by adjusting the content of ZrO2 and TiO2 in the glass formula to achieve the purpose of improving the alkali resistance of the glass fiber, but this method is costly, and at the same time, the change of the glass formula will also affect the entire drawing process of the glass fiber, resulting in product performance. Fluctuation, and after adjusting the metal oxide composition in the glass fiber content, the mechanical properties and other physical properties of the glass fiber will be greatly affected, so a new preparation method for alkali-resistant glass fiber is found, while retaining the original E It is particularly important to improve the alkali resistance of E glass fiber on the basis of the excellent physical properties of glass fiber. In summary, the innovation and improvement of the preparation method for alkali resistant glass fiber with high infrared absorption is the general trend of the development of glass fiber industry.
